PSA: You're currently accustomed to a bear market and you WILL try to sell too early

Imagine you're an astronaut going into space for the first time. You've studied for many years and know to expect zero-gravity. Perhaps you've even trained on simulators and gotten an estimation of how it might feel.
First-time astronauts invariably have the same feedback:
"Nothing could've prepared me for space. There's absolutely nothing like it."
Embarking on your first bull run is much like going into space.
You may have read about it, done some paper trading, maybe even simulated going through 2016-2017, but nothing can prepare you for the gut-wrenching, schizophrenic ride of ecstasy of having real money on the line.
Your intuition will fail you. You've grown all your life in regular gravity and have developed visual-spatial senses that work well on Earth.
When you throw an orange, you expect it to fall. When you see Bitcoin go up 15%, you expect it to flag then come back down to support.
What's most insidious is that your instincts you've developed run subconsciously directing you to make mistakes. Much like an astronaut spends a day getting acclimated to space, give yourself time and patience to get used to the new normal.
You will sell too early, thinking that on Earth, oranges don't normally travel that far. I'm here to tell you when you're going to the moon, oranges keep on going, much further than you'd expect.
The reason why veterans tell you to hodl is because it's the most effective advice helping you learn that you are weightless in space. Once Bitcoin goes on a run, the fatal mistake is pulling the ripcord too quickly. This causes you to get stuck in fiat watching day after day of losing value denominated in BTC. This is the primary cause for people fomo'ing back in higher only to get rekt when Bitcoin comes down from its local top.
If you're hodling Bitcoin, no one can tell you to get off the rocket ship. Ride it all the way to the moon with us. 10M by 2030 is my best estimation.

I'm kinda ok with MCO -> CRO Swap; a indepth personal view

EDIT: this post https://www.reddit.com/Crypto_com/comments/i2yhuz/open_letter_to_kris_from_one_of_cdcs_biggest/ from u/CryptoMines expresses my sentiments and concerns better than I could ever put into words myself. I'd say read his/her post instead.
Very long post ahead, but TL;DR, I actually see this swap as a positive change, despite fearing for what it may do to my portofolio, and having mixed feelings about its consequences on CDC reputation.Before I start, for the sake of context and bias, here's my personal situation as a CDC user:
  1. I'm just a average Joe, with a 500 MCO Jade card. I bough 50 MCO at 5,22€ in September 2019 and staked for Ruby, then bough 440 MCO at 2.47€ in March 2020 and upgraded to Jade. The total amount of MCO I own is currently 515, and everything above the 500 stake is cashback rewards.
  2. I bought MCO exclusively for the card and bonus Earn interest benefits, and had no plans to unstake my MCO. Now with the swap, definetly won't unstake.
  3. The MCO -> CRO conversion rates increased the fiat value of my MCO in about 1000€.
  4. I own a decent amount of CRO, wich I bought at ~0,031€ in March 2020.
  5. The country where I live is crypto friendly and completely crypto-tax free; I only have to pay income tax if I deposit a certain threshold of fiat in my bank.
Take all these factors into account as possible (if not major) influencers or bias on my opinions; both the emotional and economical ones. Call me a fool or a devil's advocate if you want, but keep your torches and pitchforks down. As we say here on Reddit: "Remember the human".-----------------------------------------------------------------------------------------------------------------------------------------------------
Like all of you, I woke up to find this anouncement, wich came right the #[email protected] out of nowere, and gives you little to no options. Good or bad, this announcement arrived as basicly a "comply or die" choice. Emotionally, this came as both terrifying and disgusting; but rationally, I cannot blame CDC for it.
Because wether we like it or not, CDC is a centralized company, and the MCO tokens were never a stock or legally binding contract; something wich pretty much every crypto company or ICO warns in their T&C and risk warnings. Not to mention the mostly unregulated status of the cryptocurrency and. I'll call this "dishonest" any day, but I cannot see it as a "scammy" since I can't see how they broke any rules or terms.
A scammer would take your money/assets away, but CDC is offering you to swap it for another asset wich you can sell right away if you want. And at current price, it is still worth more or less as much fiat as MCO cost at the 5 $/€ wich was more or less the comunity standard used for calculating the card prices. And by that, I mean that the fiat value of 50/500/5000 MCO (as CRO) is actually not far from the 250/2500/25'000 $/€ that the comunity commonly used as standard when calculating the ROI and (under)valuation of MCO.
So CDC is at least trying to give us the option to get (some) our money back, and not at a unfair rate. If you happened to buy MCO at a price higher than this, I can't see how that's CDC's fault, just as I don't see anyone blaming Bitcoin or Altcoins for getting them stuck at the top of the 2017 bubble burst.
I read many posts in this reddit calling this a "backstab" and "betrayal" of early investors and for the people who "believed in MCO". Emotionally, I share your sentiment.But after thinking it for a while, I'd say this was actually very rewarding for early investors and long term MCO supporters. As CDC clearly sates in the swap rules; nobody is going to lose their card tier or MCO stake benefits (at least not yet), and your stake DOES NOT unstake automatically after 180 days. Actually, so far they never did unstake automatically, you had to manually unstake yourself.
With this in mind, everyone who already got their cards, or at least staked MCO to reserve one, basicly got them 3-5 times cheaper than future users; and IMHO, now the $/€ price of cards feels more fair and sustainable compared to their benefits.So in a sense, everyone who supported and believed on the MCO for its utility (i.e. the card and app benefits) has been greatly rewarded with perks that they get to keep, but are now out of reach for a lot of people.Likewise, the people who believed and invested in CRO (for whatever reason), have also been rewarded, as their CRO tokens now have more utility.
So either the price of CRO crashes down to around 0.05 $/€, or the people who bought MCO/CRO early or cheap are now massively benefited. But then again, so is everyone who bought or mined Bitcoin in its early days, or invested in Bitcoin at crucial points of its history... how is that unfair? Some people bought Ethereum at 1'400 $ on a mix of hopes/promises that it would continue to rise; it didn't. And even today with DeFi and ETH 2.0 ever closer, it is still far from that price.
And I know what some of you are thinking: "The cards aren't avaiable in my country yet, that's why I didn't buy/stake."Well, they weren't avaiable in my country either when I staked 50 MCO. Heck, the cards weren't avaiable in anyones country when MCO started, but many people still bought it and staked it. That's exacly what "early adopter", "long supporter" and "believing in MCO" means.
On the other hand, the people who invested on MCO as a speculative asset and decided to HODL and hoard MCO, hoping for its price to moon and then sell MCO at big profit, had their dreams mercilessly crushed by this swap... and good lord, I feel their pain.But this is also where I'll commit the sin of being judgemental, because IMHO, speculating on MCO never made any sense to me; MCO was a utility token, not a value token, so it should not (and could not) ever be worth more than the value of its utility. That's basicly how stablecoins and PAXG are able to stay stable; because nobody will pay more/less than the value of the asset/service they represent.
Tough now that I'm looking at the new card stake tiers in CRO, I have to give credit to the MCO hodlers I just now criticised; maybe you were right all along. Unless the price of CRO crashes or corrects, I wich case, I un-rest my case.
One thing I'll agree with everyone tough, is that I fell that CDC just suckerpunched it's comunity. Because even if we have no vote on its decisions (wich again, we aren't necessarily entitled to, since they are a privante and centralized business) they should/could have warned that this was in their plans well in advance; if anything to allow those who wouldn't like it to exit this train calmly.
Also the CRO stake duration reset. The mandatory reset of your CRO stake for taking advantage of the early swap bonus feels like another gut-punch.
-----------------------------------------------------------------------------------------------------------------------------------------------------
Now that we got emotional feelings out of the way, here's my sentiment about how this will affect the overall CDC ecossystem.
One common criticism of the sustainability of MCO was that its supply cap could never allow a large number of cards to be issued, and how could CDC keep paying the cashbacks and rebates. On the oposite corner, one of the major criticisms of the sustainability of CRO, was it's ridiculously huge supply cap and inflation caused by the gradual un-freezing and release of more CRO into the system.
But now that MCO and CRO became one, it might just have made both issues more sustainable. Now the huge supply cap of CRO makes more sense, as it allows a much larger number of future users to stake for cards (at higher costs, but still). And because most card cashback is small parcels, this large supply also ensures that CDC can keep paying said cashbacks for a long time; especially since it can be semi-renewable trough the trading fees we pay in CRO.
Before this, the MCO you got as cashback had no use, other than selling it for fiat or speculate on its price. But CRO can be used, at the very least, to receive a discount on trading fees. And everytime you pay trading fees in CRO or spend CRO on a Syndicate event, some of that CRO goes back to CDC, wich they can use to keep paying the cahsback/rebates.
And keep in mind, the technicalities of CRO can be changed, as well as the perks and utilities it can be used for. So even if this current model doesn't fix everything (wich it probably doesn't) it can still be changed to patch problems or expand its use.
Another obvious potentially positive outcome of this, is that now CDC only has to focus on 1 token, so it makes it easier to manage and drive its value. People complained that CDC was neglecting MCO over promoting CRO, but now they can focus on both services (cards/exchange) at the same time. Sure, this might not bring much advantage to the common customer, but its probably a major resource saver and optimizer at corporate levels; wich in the long term ultimately benefits its customers.
Much like Ethereum is undergoing major changes to ensure its scalability, the crypto companies themselves also have to change to acommodate the growing number of users, especially as the cryptomarket and DeFi are growing and becoming more competitive. Business strategies that were once successfull became obsolete, and exchanges that once held near-monopolies had to adjust to rising competitors. There is no reason why CDC shouldn't keep up with this, or at least try to.
Point is, the financial markets, crypto or otherwise, are not a status quo haven. And when something is wrong, something has to be changed, even if it costs. The very rise of cryptocurrencies and blockchain, wich is why we are here in the first place, is a perfect example of this, as it experiments and provides alternatives to legacy/traditional products and technologies.
Was this the best solution to its current problems? Is this what will protect us as customers from a potentially unsustainable business model? I have no idea.
This change ripped me too from my previous more or less relaxed status quo (the safety of the value of the CRO I bough for cheap), along with CRO late investors wich now probably fear for the devaluation of their CRO. To say nothing of the blow this represents for my trust (and I believe everyone elses trust) on CDC and its public relations. It's not what CDC did, it's how they did it.
------------------------------------------------------------------------------------------------------------------------------------------------
Wether you actually bothered to read all I wrote or just skip everything (can't blame you), I'm eager to hear your opinions and whatever criticisms on my opinions you may have.
If you just want to vent at me, you are welcome too; now you can raise your pitchforks and torches.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

How I plan to identify and sell the top of the next market cycle.

In this post I will share with you some of the strategies I will use to identify the next market cycle top so I can sell for maximum profits (and of course buy back in later in the subsequent bear market!) In the first part of this post I will discuss the resources I will use and in the second part I will discuss tactics in selling and risk management.

Indicators

As the bull run begins to drag on and the price of ETH starts getting closer and closer to $10k I will begin to start watching many of the data science charts over at Look into Bitcoin. This will not be the only source I will use since there are great custom tools on TradingView too as well as more subjective indicators such as friends and family talking crypto and hearing about crypto again in the mainstream media. I’d also like to note that many of the indicators I will be looking at will be Bitcoin focused despite my ETH centred portfolio. Like it or not, this market is still Bitcoin dominated and despite the many proponents of an ETH flippening (myself included), it is quite likely that we will not see it this cycle due to the macro investing environment favouring assets which are good stores of value to weather the uncertainty. Ultimately, Bitcoin has the best store of value meme in crypto and that will be very powerful in the coming years.
I think it is likely that the time for Ethereum or a network like Ethereum with a yielding asset (ETH under ETH 2.0) and a native economy of DeFi, DApps, NFTs and much more will be once all of the stock market uncertainty is over and investors are ready to take on more risk again. I am of course still expecting Ethereum and altcoins to outperform Bitcoin this cycle. However, I think that Bitcoin losing the number 1 spot will be more likely to happen between 2023 and 2030 rather than in the next 2-3 years. I hope I am wrong though.
While most of the indicators on Looking into Bitcoin are useful, I will list the ones I’ll be focusing on the most here:
And finally my favourite, the Golden Ratio Multiplier. This indicator has been remarkably accurate at predicting tops using the golden ratio (1.6) and the fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, 21) multiplied by the 350 day moving average. With each market cycle, the 350 day moving average is multiplied by the next number down in the fibonacci sequence. For example, the 2013 peak only just passed above the 350 day moving average multiplied by 8 and the 2017 bull market just touched the 350 day moving average multiplied by 5. So if this indicator is to work in the next cycle, we can expect the price to slightly exceed 3 times the value of the 350 day moving average. This indicator also worked for Ethereum in the 2017 bull run. While there is no graph for it, on the 13th of January, when ETH hit a peak of $1,419, the 350 day moving average was at $270. $270 multiplied by 5 is $1,350. If you sold at $1,350 you sold incredibly close to the top and I don’t think that any macro traders/long term traders would complain about that timing.
I’d like to note that while indicators like the Golden Ratio Multiplier factors in for less explosive growth each cycle, not all of the above indicators do. So be cautious of this when you think the peak is near as it may be closer than you think. In saying that, there is a lot of luck involved so I should also point out that it also might not be closer than you think. However, it would be better to sell before the peak at say $10,000/BTC as of 2017 than to be left holding all of your crypto when the bear market begins since Bitcoin didn’t spend much time above $10,000/BTC after the $20K peak. Ultimately it is up to you to decide your risk appetite and how well you want to try and time the market. For me, I will definitely be on the conservative side so that I don’t miss the boat completely and hopefully I will be able to sell most of my crypto just before we peak rather than afterwards.

Risk Management

Since timing the top requires a lot of luck, a good method of mitigating the risk is to spread out when you sell. I’m going to share with you my personal strategy but I recommend that you create your own strategy or use this as a basis from which you can use to adjust and tweak it to optimally suit your situation. If you have a large stack, you will probably want to sell early since you might not need such spectacular gains to lock in some life changing money. On the other hand, if you have a smaller stack or if you are younger, you can afford to take more risk and might want to try and time the absolute peak a bit better to get that much closer to making some life changing money. Personally, while my stack isn’t very big in dollar terms, it is a significant % of my net worth and so I don’t have a high risk tolerance with it (at least relative to other people in crypto!) For this reason I will be selling a little bit on the early side.
My plan has three pots of crypto. 20% of my crypto I will hold indefinitely since I very strongly believe in the long term prospect of ETH and BTC as investments. This way if I time the markets terribly, I will always have some skin in the crypto game. The second pot of crypto is 40% which I will sell on the way up to take some profits and I don’t intend on putting this money back into crypto. Initially I will be selling very small amounts of this 40% and as the indicators listed above get closer and closer to calling a top, I will sell larger proportions of this crypto. I haven’t set specific target numbers since things change fast in this space and I feel like the best decisions in this case are made in the moment. For example, estimating a market top is hard when it is 2-3 years away, but it is much easier when it is just months or weeks away. Once again, this is just personal preference. Many of you will find that setting targets now makes it easier for you to pull the trigger and take some profits when everyone else is calling $1M BTC while it is at $100K or calling for $100K ETH when the current price might be $10K.
Finally, the last 40% I will sell all at once when I feel like we are at the top and I am confident that the price will be lower a year on from that point in time. With this 40% I will try and buy back during the bear market with the help of many of the same indicators I listed above from Look into Bitcoin. I will also use some indicators which I didn’t mention above since some are better designed at identifying market bottoms. My goal is to be able to buy back the number of BTC and ETH I held before I sold anything with this 40% (plus the 20% I didn’t sell). This is a big ask but it is better in life to set hard goals that seem unattainable or unrealistic than it is to set easy goals.
To summarise my portfolio strategy, 20% of my portfolio is an indefinite hold, 40% I will sell on the way up and I do not intend on buying back into crypto with this money so I can avoid being over-exposed to crypto. The last 40% I will use to try and sell the top and buy the bottom.

Closing Notes

As a closing note I would like to say that it will be important to be aware of the power of greed and FOMO. Do not under-estimate these emotions and try to remain a grounded and rational investor. Don’t be scared to take profits. I know from experience trading altcoins that it is better to exit a position early and miss out on another 100% price increase than it is to hold through a bear market and take >90% losses. If you go into this bullrun telling yourself you will take profits on the way up, you will have no reason to regret any early sales since you will know that you made a rational trade and not an emotional trade.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

6 Reasons Why Serum Won't Succeed

6 Reasons Why Serum Won't Succeed

The world of DeFi is exploding but is it all it’s made out to be?

DeFi (decentralised finance) is most certainly the buzz in the crypto world this minute. It’s bringing similar feelings which was the 2017/18 ICO phase, where a mammoth of new projects begun to explode onto the scene, each with their own promise of new innovation and use case.
Hindsight has shown us that most of those projects have ultimately failed, or worse, were outright scams that took advantage of not so wise investors looking to make a buck. Obviously, not all projects fit that description, with many teams still around today working on and delivering their individual visions. Crypto is, after all, still a big experiment of new technology.

Enter DeFi: Serum

DeFi has exploded into the limelight over the last few months, with some tokens appreciating hundreds of percent in price. It appears to be the catalyst that has driven a huge market shift in the crypto world, and for those who’ve been around a number of years, this is a welcome change.
In this piece, I’m going to examine a particular project called Serum.
Serum is the world’s first completely decentralized derivatives exchange with trustless cross-chain trading brought to you by Project Serum.
The Serum Project is aiming to create both a decentralised exchange and a cross-chain swapping mechanism. In this article, I’m going to focus solely on the cross-chain swapping aspect of Serum.
Although the Serum whitepaper is quite short and lacking in detail, it is useful to derive some understanding of how the cross-chain swapping protocol should work. Throughout this review, I will use it to describe how the imagined protocol works.

Overview

Let's assume Alice wants to trade some BTC for ETH and Bob wants to trade some ETH for BTC using Serum. These two users are matched and agree on a price using an on-chain order book on the Solana blockchain (whitepaper provides no practical details on how to do this).
Once these users are matched, Bob must send the ETH he wants to trade to an Ethereum smart contract, plus some amount of ETH ~200 USD worth (see section 4 below) to the smart contract as collateral. Alice will also need to send some collateral to the smart contract. Once this initial setup process is complete Alice then has to send her BTC to Bob’s BTC address and if Bob receives the BTC from Alice he can then release his ETH from the smart contract sending it to Alice’s ETH address. Upon completion of this both Alice and Bob are refunded their ETH collateral.
So what happens if something goes wrong? For example, say Alice never sends BTC to Bob, after some period of time Bob can initiate a dispute. When the dispute begins both Alice and Bob present a portion of the Bitcoin blockchain information to the smart contract (see section 3). The smart contract then decides whether or not Alice did send BTC to Bob. If she hasn’t then the smart contract returns Bob's ETH and collateral to Bob and also takes Alice’s ETH collateral and gives that to Bob. The same occurs in reverse if Alice sends BTC but Bob never approves the transfer of ETH from the smart contract.
This scheme seems pretty simple, there’s no oracles and no centralised parties, however, it has a number of disadvantages.

1. User-Provided Collateral Is Bad for User Experience

Each time a user conducts a swap they must reserve some percentage or fixed amount to cover the collateral for the swap. This collateral amount needs to be present to prevent griefing attacks where users initiate swaps with no intention of ever following through and sending funds to the alternate participant.
However, this creates a poor user experience as both Alice and Bob need to have at least the value of the dispute fee committed to the contract in collateral before they conduct a swap. This is totally foreign from the normal exchange experience in which you only require a single coin and a single transaction to begin trading. For example, if using Serum to trade Bitcoin you would need to hold Bitcoin and ~200$ of Ethereum and also interact with the Ethereum chain before any swap occurs. This adds unnecessary complexity and confusion, especially for newcomers to the crypto space.

2. ETH Must Always Be on One Side of the Swap

Although the Serum method of cross-chain swapping could occur on any blockchain with smart contracts, the Serum whitepaper makes it clear the Serum arbitration contract is going to be deployed on the Ethereum blockchain. This means one party must always be locking the full value of the trade in ETH using an Ethereum smart contract.
This makes it impossible, for example, to do a single step trade between Bitcoin and Monero since the swap would need to be from Bitcoin to ETH first and then from ETH to Monero. This is comparable to other proposed cross-chain swap systems like Thorchain and Blockswap, however since those networks use AMM’s (automated market makers)and decentralized vaults to take custody of funds, the user needs not to interact with the intermediary chain at all.
Instead in Serum, the user wanting to swap Bitcoin to Monero will need to do the following steps:
  1. Send Ethereum collateral to the Serum arbitration contract
  2. Send Bitcoin to the user they are swapping with.
  3. Receive Ethereum
  4. Send Ethereum back to Serum arbitration contract
  5. Receive Monero
  6. Send Ethereum out of Serum arbitration contract
  7. Receive back Ethereum collateral
It might be possible to remove or simplify step 4, depending on how the smart contract is built, however, this means a swap from BTC to Monero would require 2 Ethereum and 1 Bitcoin transaction in the best-case scenario. Compared with the experience of other cross-chain swapping mechanisms, which only require the user to send a single transaction to swap between two assets, this is very poor user experience.

3. Proving Transactions on Arbitrary Chains to a Smart Contract Is Not Trivial

Perhaps the most central part of the Serum cross-chain swapping mechanism is left completely unexplored in the Serum whitepaper with only a brief explanation given.
“[The] Smart Contract is programmed to parse whether a proposed BTC blockchain is valid; it can then check which of Alice and Bob send the longer valid blockchain, and settle in their favor”
This is not a trivial problem, and it is unclear how this actually works from the explanation given in the Serum whitepaper. What actually needs to be presented to the smart contract to prove a Bitcoin transaction? Typically when talking about SPV the smart contract would need the block headers of all previous blocks and a merkle inclusion proof. This is far too heavy to submit in a dispute. Instead, Serum could use NIPoPoW, however, these proofs only work on chains with fixed difficulty and are still probably prohibitively too large (~100KB) to be submitted as a proof to a contract. Other solutions like Flyclient are more versatile, but proof sizes are much larger and have failed to see much real-world adoption.
Without explaining how they actually plan to do this validation of Bitcoin transactions, users are left in the dark about how secure their solution actually is.

4. High Dispute Fees Force Large Collateral on Small Trades

Although disputes should almost never happen because of the incentives and punishments designed into the Serum protocol, the way they are designed has negative impacts on the use of the network.
Although the Serum whitepaper does not say how the dispute mechanism works, they do say that it will cost about ~100 USD in GAS to dispute a swap.
Note: keep in mind that the Serum paper was published in July 2020 when the gas price was about 50 Gwei, as Ethereum use has picked up over the past month we have seen average GAS prices as high as 250 Gwei, with the average price right now about 120 Gwei.
This means that at the height of GAS prices it could have cost a user ~500 USD to dispute a swap.
This means for the network to ensure losing cross-chain swaps aren’t made each user must deploy at least $200 in collateral on each side. It may be possible to lower this to collateral if we assume the attacker is not financially motivated, however, there is a lower bound in which ransom attacks become possible on low-value trades.
Further and perhaps more damagingly, this means in a trade of any size the user needs to have at least 300 USD in ETH laying around. 100 USD in ETH for the required collateral and 200 USD if they need to challenge the transaction.
This further adds to the poor user experience when using Serum for cross-chain swapping.

5. Swaps Are Not Set and Forget

Instead of being able to send a transaction and receive funds on the blockchain you are swapping to, the process is highly interactive. In the case where I am swapping ETH for Bitcoin, the following occurs:
If the Bitcoin transaction is never received then I need to wait for a timeout to occur before I can participate in the dispute process.
And on the Bitcoin side (assuming the seller is ready), the following must take place:
If the Seller never accepts the Bitcoin I sent to him then I need to wait on line for the dispute process.
This presents a strange user experience where the seller or seller’s wallet must be left online during this whole process and be ready to sign a new transaction if they need to dispute transactions or unlock funds from a smart contract.
This is different from the typical exchange or swapping scenario in which, once your funds are sent you can be assured you will receive the amount you expected in your swap back to you, without any of your wallets needing to remain online.

6. The Serum Token Seems to Lack a Use Case

The cross-chain swapping protocol Serum describes in its whitepaper could easily be forked and launched on the Ethereum blockchain without having any need for the Serum token. It seems that the Serum token will be used in some capacity when placing orders on the Solana based blockchain, however, the order book could just as easily be placed off with traditional rate-limiting schemes.
There is some brief mention of future governance abilities for token holders, however, as a common theme in their whitepaper, details are scarce:
Serum is anticipated to include a limited governance model based on the SRM token. While most of the Serum ecosystem will be immutable, some parameters without large security risks (e.g. future fees) may be modified via a governance vote of SRM tokens.

Conclusion

Until satisfactory answers are given to these questions I would be looking at other projects who are attempting to build platforms for cross-chain swaps. As previously mentioned, Thorchain & Blockswap show some promise in design, whilst there are some others competing in this space too, such as Incognito and RenVM. However, this area is still extremely immature so plenty of testing and time is required before we can call any of these projects a success.
If you’ve got any feedback or thoughts about Serum, cross-chain swapping or DeFi in general, please don’t be shy in leaving a comment.

Flatten the Curve. #18. The current cold war between China and America explained. And how China was behind the 2008 Wall Street financial Crash. World War 3 is coming.

China, the USA, and the Afghanistan war are linked. And in order to get here, we will start there.
9-11 happened. Most of the planet mistakenly understood terrorists had struck a blow against Freedom and Capitalism and Democracy. It was time to invade Afghanistan. Yet all of the terrorists were linked to Saudi Arabia and not Afghanistan, that didn't make sense either. Yet they invaded to find Bin Laden, an ex CIA asset against the Soviet Union and it's subjugation of Afghanistan. The land in the middle of nowhere in relation to North America and the West. It was barren. A backwater without any strategic importance or natural resources.
Or was there?
The survey for rare earth elements was only made possible by the 2001 U.S. invasion, with work beginning in 2004. Mirzad says the Russians had already done significant surveying work during their military occupation of the country in the 1980s. Mirzad also toes the line for U.S. corporations, arguing, “The Afghan government should not touch the mining business. We have to give enough information to potential investors.”
Rare Earth Elements. The elements that make the information age possible. People could understand the First Gulf War and the Geopolitical importance of oil. That was easy, but it still didn't sound morally just to have a war for oil. It was too imperialist and so they fell in line and supported a war for Kuwaiti freedom instead, despite the obvious and public manipulation at the UN by Nayirah.
This is some of her testimony to the Human Rights Council.
While I was there, I saw the Iraqi soldiers come into the hospital with guns. They took the babies out of the incubators, took the incubators and left the children to die on the cold floor. It was horrifying. I could not help but think of my nephew who was born premature and might have died that day as well. After I left the hospital, some of my friends and I distributed flyers condemning the Iraqi invasion until we were warned we might be killed if the Iraqis saw us.
The Iraqis have destroyed everything in Kuwait. They stripped the supermarkets of food, the pharmacies of medicine, the factories of medical supplies, ransacked their houses and tortured neighbors and friends.
There was only one problem. She was the daughter of Saud Al-Sabah, the Kuwaiti ambassador to the United States. Furthermore, it was revealed that her testimony was organized as part of the Citizens for a Free Kuwait public relations campaign, which was run by the American public relations firm Hill & Knowlton for the Kuwaiti government (fun fact, Hill & Knowlton also have extensive ties with Bill Gates).
So the public was aghast at her testimony and supported the war against the mainly Soviet backed, but also American supported and Soviet backed Saddam Hussein, in his war against Iran, after the Iranians refused to Ally with American interests after the Islamic Revolution.
But that was oil, this was Rare Earth Elements. There was a reason the war was called, Operation Enduring Freedom. This natural resource was far more important in the long run. You couldn't have a security surveillance apparatus without it. And what was supposed to be a war on terror was in actuality a territorial occupation for resources.
Sleeping Dragon China is next, and where there's smoke, there's fire.
Let's go point form for clarity.
• China entered the rare earth market in the mid-1980s, at a time when the US was the major producer. But China soon caught up and became the production leader for rare earths. Its heavily state-supported strategy was aimed at dominating the global rare earth industry.
• 1989 Beijing’s Tiananmen Square spring. The U.S. government suspends military sales to Beijing and freezes relations.
• 1997. Clinton secures the release of Wei and Tiananmen Square protester Wang Dan. Beijing deports both dissidents to the United States. (If you don't understand these two were CIA assets working in China, you need to accept that not everything will be published. America wouldn't care about two political activists, but why would care about two intelligence operatives).
• March 1996. Taiwan’s First Free Presidential Vote.
• May 1999. America "accidently" bombs the Belgrade Chinese Embassy.
• 2002 Price competitiveness was hard for the USA to achieve due to low to non-existent Chinese environmental standards; as a result, the US finally stopped its rare earth production.
• October 2000. U.S. President Bill Clinton signs the U.S.-China Relations Act. China's take over of the market share in rare earth elements starts to increase.
• October 2001. Afghanistan war Enduring Freedom started to secure rare earth elements (Haven't you ever wondered how they could mobilize and invade so quickly? The military was already prepared).
• 2005. China establishes a monopoly on global production by keeping mineral prices low and then panics markets by introducing export quotas to raise prices by limiting supply.
• Rare Earth Elements. Prices go into the stratosphere (for example, dysprosium prices do a bitcoin, rocketing from $118/kg to $2,262/kg between 2008 and 2011).
• In a September 2005. Deputy Secretary of State Robert B. Zoellick initiates a strategic dialogue with China. This was presented as dialog to acknowledge China's emergence as a Superpower (which China probably insisted on), but it was about rare earth elements market price.
• October 2006. China allows North Korea to conduct its first nuclear test, China serves as a mediator to bring Pyongyang back to the negotiating table with the USA.
• September 2006. American housing prices start to fall.
(At some point after this, secret negotiations must have become increasingly hostile).
• March 2007. China Increases Military Spending. U.S. Vice President Dick Cheney says China’s military buildup is “not consistent” with the country’s stated goal of a “peaceful rise.”
• Mid-2005 and mid-2006. China bought between $100b and $250 billion of US housing debt between mid-2005 and mid-2006. This debt was bought using the same financial instruments that caused the financial collapse.
• 2006. Housing prices started to fall for the first time in decades.
• Mid-2006 and mid-2007. China likely added another $390b to its reserves. "At the same time, if China stopped buying -- especially now, when the private market is clogged up -- US financial markets would really seize up." Council on Foreign Relations-2007 August
• February 27, 2007. Stock markets in China and the U.S. fell by the most since 2003. Investors leave the money market and flock to Government backed Treasury Bills.
I've never seen it like this before,'' said Jim Galluzzo, who began trading short-maturity Treasuries 20 years ago and now trades bills at RBS Greenwich Capital in Greenwich, Connecticut.Bills right now are trading like dot-coms.''
We had clients asking to be pulled out of money market funds and wanting to get into Treasuries,'' said Henley Smith, fixed-income manager in New York at Castleton Partners, which oversees about $150 million in bonds.People are buying T-bills because you know exactly what's in it.''
• February 13, 2008. The Economic Stimulus Act of 2008 was enacted, which included a tax rebate. The total cost of this bill was projected at $152 billion for 2008. A December 2009 study found that only about one-third of the tax rebate was spent, providing only a modest amount of stimulus.
• September 2008. China Becomes Largest U.S. Foreign Creditor at 600 billion dollars.
• 2010. China’s market power peaked in when it reached a market share of around 97% of all rare earth mineral production. Outside of China, there were almost no other producers left.
Outside of China, the US is the second largest consumer of rare earths in the world behind Japan.
About 60% of US rare earth imports are used as catalysts for petroleum refining, making it the country’s major consumer of rare earths.
The US military also depends on rare earths.

Beijing also demands that those outlets, as well as TIME and Voice of America, share information with the government about their operations in China. The Chinese Foreign Ministry says the moves are in response to the U.S. government’s decision earlier in the year to limit the number of Chinese journalists from five state-run media outlets in the United States to 100, down from 160, and designate those outlets as foreign missions.
And here we are. You may have noticed the Rare Earth Elements and the inclusion of Environmental Standards. Yes these are key to understanding the Geopolitical reality and importance of these events. There's a reason the one child policy stopped. Troop additions.
I believe our current political reality started at Tiananmen square. The protests were an American sponsored attempt at regime change after the failure to convince them to leave totalitarian communism and join a greater political framework.
Do I have proof? Yes.
China, as far as I'm concerned, was responsible for the 2008 economic crisis. The Rare Earth Elements were an attempt to weaken the States and strengthen themselves simultaneously. This stranglehold either forced America to trade with China, or the trade was an American Trojan horse to eventually collapse their economy and cause a revolution after Tiananmen Square failed. Does my second proposal sound far fetched? Didn't the economy just shut down in response to the epidemic? Aren't both sides blaming the other? At this POINT, the epidemic seems to be overstated doesn’t it? Don't the casualties tend to the elder demographic and those already weakened by a primary disease?
Exactly the kinds who wouldn't fight in a war.
Does this change some of my views on the possibility of upcoming catastrophes and reasons for certain events? No. This is Chess, and there are obvious moves in chess, hidden moves in chess, but the best moves involve peices which can be utilized in different ways if the board calls for it.
Is all what it seems? No.
I definitely changed a few previously held beliefs prior to today, and I would caution you in advance that you will find some previously held convictions challenged.
After uncovering what I did today, I would also strongly suggest reading information cautiously. This is all merely a culmination of ending the cold war, and once I have events laid out, you will see it as well.
At this moment, the end analysis is a war will start in the near future. This will be mainly for a few reasons, preemptive resource control for water and crops, population reduction can be achieved since we have too many people, not enough jobs, and upcoming resource scarcity.
Did you notice my omission of rare earth elements? This is because of Afghanistan. I would wager China or Russia is somehow supporting the continued resistance through Iran. But events are now accelerating with China because the western collation has already begun to build up their mines and start production.
Do you remember when Trump made a "joke" about buying Greenland? Yeah. It turns out that Greenland has one of the largest rare earth mineral deposits on the planet.
Take care. Be safe. Stay aware and be prepared.

How I plan to identify and sell the top of the next market cycle.

In this post I will share with you some of the strategies I will use to identify the next market cycle top so I can sell for maximum profits (and of course buy back in later in the subsequent bear market!) In the first part of this post I will discuss the resources I will use and in the second part I will discuss tactics in selling and risk management.

Indicators

As the bull run begins to drag on and the price of ETH starts getting closer and closer to $10k I will begin to start watching many of the data science charts over at Look into Bitcoin. This will not be the only source I will use since there are great custom tools on TradingView too as well as more subjective indicators such as friends and family talking crypto and hearing about crypto again in the mainstream media. I’d also like to note that many of the indicators I will be looking at will be Bitcoin focused despite my ETH centred portfolio. Like it or not, this market is still Bitcoin dominated and despite the many proponents of an ETH flippening (myself included), it is quite likely that we will not see it this cycle due to the macro investing environment favouring assets which are good stores of value to weather the uncertainty. Ultimately, Bitcoin has the best store of value meme in crypto and that will be very powerful in the coming years.
I think it is likely that the time for Ethereum or a network like Ethereum with a yielding asset (ETH under ETH 2.0) and a native economy of DeFi, DApps, NFTs and much more will be once all of the stock market uncertainty is over and investors are ready to take on more risk again. I am of course still expecting Ethereum and altcoins to outperform Bitcoin this cycle. However, I think that Bitcoin losing the number 1 spot will be more likely to happen between 2023 and 2030 rather than in the next 2-3 years. I hope I am wrong though.
While most of the indicators on Looking into Bitcoin are useful, I will list the ones I’ll be focusing on the most here:
And finally my favourite, the Golden Ratio Multiplier. This indicator has been remarkably accurate at predicting tops using the golden ratio (1.6) and the fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, 21) multiplied by the 350 day moving average. With each market cycle, the 350 day moving average is multiplied by the next number down in the fibonacci sequence. For example, the 2013 peak only just passed above the 350 day moving average multiplied by 8 and the 2017 bull market just touched the 350 day moving average multiplied by 5. So if this indicator is to work in the next cycle, we can expect the price to slightly exceed 3 times the value of the 350 day moving average. This indicator also worked for Ethereum in the 2017 bull run. While there is no graph for it, on the 13th of January, when ETH hit a peak of $1,419, the 350 day moving average was at $270. $270 multiplied by 5 is $1,350. If you sold at $1,350 you sold incredibly close to the top and I don’t think that any macro traders/long term traders would complain about that timing.
I’d like to note that while indicators like the Golden Ratio Multiplier factors in for less explosive growth each cycle, not all of the above indicators do. So be cautious of this when you think the peak is near as it may be closer than you think. In saying that, there is a lot of luck involved so I should also point out that it also might not be closer than you think. However, it would be better to sell before the peak at say $10,000/BTC as of 2017 than to be left holding all of your crypto when the bear market begins since Bitcoin didn’t spend much time above $10,000/BTC after the $20K peak. Ultimately it is up to you to decide your risk appetite and how well you want to try and time the market. For me, I will definitely be on the conservative side so that I don’t miss the boat completely and hopefully I will be able to sell most of my crypto just before we peak rather than afterwards.

Risk Management

Since timing the top requires a lot of luck, a good method of mitigating the risk is to spread out when you sell. I’m going to share with you my personal strategy but I recommend that you create your own strategy or use this as a basis from which you can use to adjust and tweak it to optimally suit your situation. If you have a large stack, you will probably want to sell early since you might not need such spectacular gains to lock in some life changing money. On the other hand, if you have a smaller stack or if you are younger, you can afford to take more risk and might want to try and time the absolute peak a bit better to get that much closer to making some life changing money. Personally, while my stack isn’t very big in dollar terms, it is a significant % of my net worth and so I don’t have a high risk tolerance with it (at least relative to other people in crypto!) For this reason I will be selling a little bit on the early side.
My plan has three pots of crypto. 20% of my crypto I will hold indefinitely since I very strongly believe in the long term prospect of ETH and BTC as investments. This way if I time the markets terribly, I will always have some skin in the crypto game. The second pot of crypto is 40% which I will sell on the way up to take some profits and I don’t intend on putting this money back into crypto. Initially I will be selling very small amounts of this 40% and as the indicators listed above get closer and closer to calling a top, I will sell larger proportions of this crypto. I haven’t set specific target numbers since things change fast in this space and I feel like the best decisions in this case are made in the moment. For example, estimating a market top is hard when it is 2-3 years away, but it is much easier when it is just months or weeks away. Once again, this is just personal preference. Many of you will find that setting targets now makes it easier for you to pull the trigger and take some profits when everyone else is calling $1M BTC while it is at $100K or calling for $100K ETH when the current price might be $10K.
Finally, the last 40% I will sell all at once when I feel like we are at the top and I am confident that the price will be lower a year on from that point in time. With this 40% I will try and buy back during the bear market with the help of many of the same indicators I listed above from Look into Bitcoin. I will also use some indicators which I didn’t mention above since some are better designed at identifying market bottoms. My goal is to be able to buy back the number of BTC and ETH I held before I sold anything with this 40% (plus the 20% I didn’t sell). This is a big ask but it is better in life to set hard goals that seem unattainable or unrealistic than it is to set easy goals.
To summarise my portfolio strategy, 20% of my portfolio is an indefinite hold, 40% I will sell on the way up and I do not intend on buying back into crypto with this money so I can avoid being over-exposed to crypto. The last 40% I will use to try and sell the top and buy the bottom.

Closing Notes

As a closing note I would like to say that it will be important to be aware of the power of greed and FOMO. Do not under-estimate these emotions and try to remain a grounded and rational investor. Don’t be scared to take profits. I know from experience trading altcoins that it is better to exit a position early and miss out on another 100% price increase than it is to hold through a bear market and take >90% losses. If you go into this bullrun telling yourself you will take profits on the way up, you will have no reason to regret any early sales since you will know that you made a rational trade and not an emotional trade.

ETHE & GBTC (Grayscale) Frequently Asked Questions

It is no doubt Grayscale’s booming popularity as a mainstream investment has caused a lot of community hullabaloo lately. As such, I felt it was worth making a FAQ regarding the topic. I’m looking to update this as needed and of course am open to suggestions / adding any questions.
The goal is simply to have a thread we can link to anyone with questions on Grayscale and its products. Instead of explaining the same thing 3 times a day, shoot those posters over to this thread. My hope is that these questions are answered in a fairly simple and easy to understand manner. I think as the sub grows it will be a nice reference point for newcomers.
Disclaimer: I do NOT work for Grayscale and as such am basing all these answers on information that can be found on their website / reports. (Grayscale’s official FAQ can be found here). I also do NOT have a finance degree, I do NOT have a Series 6 / 7 / 140-whatever, and I do NOT work with investment products for my day job. I have an accounting background and work within the finance world so I have the general ‘business’ knowledge to put it all together, but this is all info determined in my best faith effort as a layman. The point being is this --- it is possible I may explain something wrong or missed the technical terms, and if that occurs I am more than happy to update anything that can be proven incorrect
Everything below will be in reference to ETHE but will apply to GBTC as well. If those two segregate in any way, I will note that accordingly.
What is Grayscale? 
Grayscale is the company that created the ETHE product. Their website is https://grayscale.co/
What is ETHE? 
ETHE is essentially a stock that intends to loosely track the price of ETH. It does so by having each ETHE be backed by a specific amount of ETH that is held on chain. Initially, the newly minted ETHE can only be purchased by institutions and accredited investors directly from Grayscale. Once a year has passed (6 months for GBTC) it can then be listed on the OTCQX Best Market exchange for secondary trading. Once listed on OTCQX, anyone investor can purchase at this point. Additional information on ETHE can be found here.
So ETHE is an ETF? 
No. For technical reasons beyond my personal understandings it is not labeled an ETF. I know it all flows back to the “Securities Act Rule 144”, but due to my limited knowledge on SEC regulations I don’t want to misspeak past that. If anyone is more knowledgeable on the subject I am happy to input their answer here.
How long has ETHE existed? 
ETHE was formed 12/14/2017. GBTC was formed 9/25/2013.
How is ETHE created? 
The trust will issue shares to “Authorized Participants” in groups of 100 shares (called baskets). Authorized Participants are the only persons that may place orders to create these baskets and they do it on behalf of the investor.

Note – The way their reports word this makes it sound like there is an army of authorizers doing the dirty work, but in reality there is only one Authorized Participant. At this moment the “Genesis” company is the sole Authorized Participant. Genesis is owned by the “Digital Currency Group, Inc.” which is the parent company of Grayscale as well. (And to really go down the rabbit hole it looks like DCG is the parent company of CoinDesk and is “backing 150+ companies across 30 countries, including Coinbase, Ripple, and Chainalysis.”)

How does Grayscale acquire the ETH to collateralize the ETHE product? 
An Investor may acquire ETHE by paying in cash or exchanging ETH already owned.
Source: Creation and Redemption of Shares section on page 40 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
Where does Grayscale store their ETH? Does it have a specific wallet address we can follow? 
ETH is stored with Coinbase Custody Trust Company, LLC. I am unaware of any specific address or set of addresses that can be used to verify the ETH is actually there.
As an aside - I would actually love to see if anyone knows more about this as it’s something that’s sort of peaked my interest after being asked about it… I find it doubtful we can find that however.

Can ETHE be redeemed for ETH? 
No, currently there is no way to give your shares of ETHE back to Grayscale to receive ETH back. The only method of getting back into ETH would be to sell your ETHE to someone else and then use those proceeds to buy ETH yourself.
Source: Redemption Procedures on page 41 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
Why are they not redeeming shares? 
I think the report summarizes it best:
Redemptions of Shares are currently not permitted and the Trust is unable to redeem Shares. Subject to receipt of regulatory approval from the SEC and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. Because the Trust does not believe that the SEC would, at this time, entertain an application for the waiver of rules needed in order to operate an ongoing redemption program, the Trust currently has no intention of seeking regulatory approval from the SEC to operate an ongoing redemption program.
Source: Redemption Procedures on page 41 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
What is the fee structure? 
ETHE has an annual fee of 2.5%. GBTC has an annual fee of 2.0%. Fees are paid by selling the underlying ETH / BTC collateralizing the asset.
Source: ETHE’s informational page on Grayscale’s website - Located Here
Source: Description of Trust on page 31 & 32 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
What is the ratio of ETH to ETHE? 
At the time of posting (6/19/2020) each ETHE share is backed by .09391605 ETH. Each share of GBTC is backed by .00096038 BTC.
ETHE & GBTC’s specific information page on Grayscale’s website updates the ratio daily – Located Here
For a full historical look at this ratio, it can be found on the Grayscale home page on the upper right side if you go to Tax Documents > 2019 Tax Documents > Grayscale Ethereum Trust 2019 Tax Letter.
Why is the ratio not 1:1? Why is it always decreasing? 
While I cannot say for certain why the initial distribution was not a 1:1 backing, it is more than likely to keep the price down and allow more investors a chance to purchase ETHE / GBTC.
As noted above, fees are paid by selling off the ETH collateralizing ETHE. So this number will always be trending downward as time goes on.
Source: Description of Trust on page 32 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
I keep hearing about how this is locked supply… explain? 
As noted above, there is currently no redemption program for converting your ETHE back into ETH. This means that once an ETHE is issued, it will remain in circulation until a redemption program is formed --- something that doesn’t seem to be too urgent for the SEC or Grayscale at the moment. Tiny amounts will naturally be removed due to fees, but the bulk of the asset is in there for good.
Knowing that ETHE cannot be taken back and destroyed at this time, the ETH collateralizing it will not be removed from the wallet for the foreseeable future. While it is not fully locked in the sense of say a totally lost key, it is not coming out any time soon.
Per their annual statement:
The Trust’s ETH will be transferred out of the ETH Account only in the following circumstances: (i) transferred to pay the Sponsor’s Fee or any Additional Trust Expenses, (ii) distributed in connection with the redemption of Baskets (subject to the Trust’s obtaining regulatory approval from the SEC to operate an ongoing redemption program and the consent of the Sponsor), (iii) sold on an as-needed basis to pay Additional Trust Expenses or (iv) sold on behalf of the Trust in the event the Trust terminates and liquidates its assets or as otherwise required by law or regulation.

Grayscale now owns a huge chunk of both ETH and BTC’s supply… should we be worried about manipulation, a sell off to crash the market crash, a staking cartel? 
First, it’s important to remember Grayscale is a lot more akin to an exchange then say an investment firm. Grayscale is working on behalf of its investors to create this product for investor control. Grayscale doesn’t ‘control’ the ETH it holds any more then Coinbase ‘controls’ the ETH in its hot wallet. (Note: There are likely some varying levels of control, but specific to this topic Grayscale cannot simply sell [legally, at least] the ETH by their own decision in the same manner Coinbase wouldn't be able to either.)
That said, there shouldn’t be any worry in the short to medium time-frame. As noted above, Grayscale can’t really remove ETH other than for fees or termination of the product. At 2.5% a year, fees are noise in terms of volume. Grayscale seems to be the fastest growing product in the crypto space at the moment and termination of the product seems unlikely.
IF redemptions were to happen tomorrow, it’s extremely unlikely we would see a mass exodus out of the product to redeem for ETH. And even if there was incentive to get back to ETH, the premium makes it so that it would be much more cost effective to just sell your ETHE on the secondary market and buy ETH yourself. Remember, any redemption is up to the investors and NOT something Grayscale has direct control over.
Yes, but what about [insert criminal act here]… 
Alright, yes. Technically nothing is stopping Grayscale from selling all the ETH / BTC and running off to the Bahamas (Hawaii?). BUT there is no real reason for them to do so. Barry is an extremely public figure and it won’t be easy for him to get away with that. Grayscale’s Bitcoin Trust creates SEC reports weekly / bi-weekly and I’m sure given the sentiment towards crypto is being watched carefully. Plus, Grayscale is making tons of consistent revenue and thus has little to no incentive to give that up for a quick buck.
That’s a lot of ‘happy little feels’ Bob, is there even an independent audit or is this Tether 2.0? 
Actually yes, an independent auditor report can be found in their annual reports. It is clearly aimed more towards the financial side and I doubt the auditors are crypto savants, but it is at least one extra set of eyes. Auditors are Friedman LLP – Auditor since 2015.
Source: Independent Auditor Report starting on page 116 (of the PDF itself) of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
As mentioned by user TheCrpytosAndBloods (In Comments Below), a fun fact:
The company’s auditors Friedman LLP were also coincidentally TetheBitfinex’s auditors until They controversially parted ways in 2018 when the Tether controversy was at its height. I am not suggesting for one moment that there is anything shady about DCG - I just find it interesting it’s the same auditor.
“Grayscale sounds kind of lame” / “Not your keys not your crypto!” / “Why is anyone buying this, it sounds like a scam?” 
Welp, for starters this honestly is not really a product aimed at the people likely to be reading this post. To each their own, but do remember just because something provides no value to you doesn’t mean it can’t provide value to someone else. That said some of the advertised benefits are as follows:
So for example, I can set up an IRA at a brokerage account that has $0 trading fees. Then I can trade GBTC and ETHE all day without having to worry about tracking my taxes. All with the relative safety something like E-Trade provides over Binance.
As for how it benefits the everyday ETH holder? I think the supply lock is a positive. I also think this product exposes the Ethereum ecosystem to people who otherwise wouldn’t know about it.
Why is there a premium? Why is ETHE’s premium so insanely high compared to GBTC’s premium? 
There are a handful of theories of why a premium exists at all, some even mentioned in the annual report. The short list is as follows:
Why is ETHE’s so much higher the GBTC’s? Again, a few thoughts:

Are there any other differences between ETHE and GBTC? 
I touched on a few of the smaller differences, but one of the more interesting changes is GBTC is now a “SEC reporting company” as of January 2020. Which again goes beyond my scope of knowledge so I won’t comment on it too much… but the net result is GBTC is now putting out weekly / bi-weekly 8-K’s and annual 10-K’s. This means you can track GBTC that much easier at the moment as well as there is an extra layer of validity to the product IMO.
I’m looking for some statistics on ETHE… such as who is buying, how much is bought, etc? 
There is a great Q1 2020 report I recommend you give a read that has a lot of cool graphs and data on the product. It’s a little GBTC centric, but there is some ETHE data as well. It can be found here hidden within the 8-K filings.Q1 2020 is the 4/16/2020 8-K filing.
For those more into a GAAP style report see the 2019 annual 10-K of the same location.
Is Grayscale only just for BTC and ETH? 
No, there are other products as well. In terms of a secondary market product, ETCG is the Ethereum Classic version of ETHE. Fun Fact – ETCG was actually put out to the secondary market first. It also has a 3% fee tied to it where 1% of it goes to some type of ETC development fund.
In terms of institutional and accredited investors, there are a few ‘fan favorites’ such as Bitcoin Cash, Litcoin, Stellar, XRP, and Zcash. Something called Horizion (Backed by ZEN I guess? Idk to be honest what that is…). And a diversified Mutual Fund type fund that has a little bit of all of those. None of these products are available on the secondary market.
Are there alternatives to Grayscale? 
I know they exist, but I don’t follow them. I’ll leave this as a “to be edited” section and will add as others comment on what they know.
Per user Over-analyser (in comments below):
Coinshares (Formerly XBT provider) are the only similar product I know of. BTC, ETH, XRP and LTC as Exchange Traded Notes (ETN).
It looks like they are fully backed with the underlying crypto (no premium).
https://coinshares.com/etps/xbt-provideinvestor-resources/daily-hedging-position
Denominated in SEK and EUR. Certainly available in some UK pensions (SIPP).
As asked by pegcity - Okay so I was under the impression you can just give them your own ETH and get ETHE, but do you get 11 ETHE per ETH or do you get the market value of ETH in USD worth of ETHE? 
I have always understood that the ETHE issued directly through Grayscale is issued without the premium. As in, if I were to trade 1 ETH for ETHE I would get 11, not say only 2 or 3 because the secondary market premium is so high. And if I were paying cash only I would be paying the price to buy 1 ETH to get my 11 ETHE. Per page 39 of their annual statement, it reads as follows:
The Trust will issue Shares to Authorized Participants from time to time, but only in one or more Baskets (with a Basket being a block of 100 Shares). The Trust will not issue fractions of a Basket. The creation (and, should the Trust commence a redemption program, redemption) of Baskets will be made only in exchange for the delivery to the Trust, or the distribution by the Trust, of the number of whole and fractional ETH represented by each Basket being created (or, should the Trust commence a redemption program, redeemed), which is determined by dividing (x) the number of ETH owned by the Trust at 4:00 p.m., New York time, on the trade date of a creation or redemption order, after deducting the number of ETH representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust (converted using the ETH Index Price at such time, and carried to the eighth decimal place), by (y) the number of Shares outstanding at such time (with the quotient so obtained calculated to one one-hundred-millionth of one ETH (i.e., carried to the eighth decimal place)), and multiplying such quotient by 100 (the “Basket ETH Amount”). All questions as to the calculation of the Basket ETH Amount will be conclusively determined by the Sponsor and will be final and binding on all persons interested in the Trust. The Basket ETH Amount multiplied by the number of Baskets being created or redeemed is the “Total Basket ETH Amount.” The number of ETH represented by a Share will gradually decrease over time as the Trust’s ETH are used to pay the Trust’s expenses.
