Mining Ethereum in 2020. It's a good time.

There are two main theories about how ETH will develop further. One suggests that ETH is completely dependent on Bitcoin, it rises and falls along with it at the same time. The second theory argues that Ethereum may soon lose its altcoin status and become an independent cryptocurrency - according to researchers at the San Francisco Open Exchange (SFOX), for example.
Since the beginning of the year, ETH has risen in price by more than 34%, and this trend continues. Some experts expect the coin to rise to $400- $500 by the end of 2020, the most positive optimists expect it to reach $2,000 in the next year. And all because of the DeFi’s boom and the massive tokenization process, which became possible thanks to the Ethereum technology.
Foolproof Mining
Today, to start mining Ether, you do not need to undergo special training or be super tech-savvy. Forums have useful information for beginners. Mining equipment manufacturers are investing more and more money in creating the most productive and easy-to-use and energy-efficient hardware possible.
According to Technavio's calculations, the volume of the world market for mining equipment in 2019-2023 will grow by $2.7 billion. Users usually benefit from such a race, because when the opportunity to “show off technologies” ends, vendors begin to reduce prices for their solutions and offer special conditions.
As for software, it is better to mine on a specialized one and avoid unnecessary problems. For example, ethOS or CoinFly's COS copes well with high loads, manages mining processes of any scale and on any equipment through a single interface, automates routine and controls income and expenses.
Profit in Mining Pool
Great thing about mining in 2020 is that you can choose a convenient profitable pool that will regularly fill your virtual pockets with Ether and sleep peacefully, read about what to look for when choosing a pool here. The main thing is to understand which one brings more money. Take a look at the CoinFly pool, which according to independent tests’ giving well profit…
Hedge risks
Whenever you’re afraid of losing income due to price fluctuations, buy Put Options (on Binance, for example) oand short ETH futures.
Thank You!

Hulk.Finance: A Combination of DeFi and High Frequency Trading

DeFi continues to push the limits of blockchain technology. Whether its staking a native token for a second token from the same ecosystem, locking liquidity for an eternity to promote liquidity providing and the benefits of locking tokens, or simply creating new tokenomics that can be tested and studied, DeFi is exploring all avenues to produce the next breakout token such as YFI. Hulk.finance has stepped in to do just that.

Hulk.finance (Contract Address: 0xE1f8CD01aB04b51d02C6fb2BCA61B03fB5e33B99**)** is an ERC20 token which plans to utilize a DAO (Decentralized Autonomous Organization) format that will be community governed in order to promote high frequency trading in a manner only DeFi can bring to the table. As stated on their website, “Our project connects a high-yield partner HFT (High Frequency Trading) fund that has successfully worked from the beginning of 2020 and has year-to-date yields of more than 40%. The fund size is more than 70 millions USD and they operate on several cryptocurrency exchanges like Binance and Bithumb with their API robots. What is good — automated trading does not require continuous uptrend of the Bitcoin price. We have seen good results during Bitcoin breakouts and breakdowns. We want to have the same yields from our investments. But there is a problem — they work with an entrance barrier of 1,000,000 USDT, like many private banking services or high-yield ETFs. Our basic idea is to make a kind of DeFi staking pool and put it under the management of the HFT fund. We will develop all infrastructure for connecting finance flows, deposits, and withdrawals.

The HULK total supply is 100,000 Tokens. Distribution breakdown is as follows:

The project is new but already has a road-map to help guide their lofty ambitions. The first step begins with the formation of the pre-sale and Liquidity pool on Uniswap which is currently ongoing. Secondly, they will distribute Hulk tokens via staking farms. As described in their website they “will run staking farms for farming 80,000 HULKs*. You will need to stake appropriate tokens on the selected farms to get your share of rewards in HULKs. Farm 1 will farm rewards of 60,000* HULKs within 15 days, staking token — ETH-HULK LP Uniswap V2. Farm 2 will farm rewards of 10,000 HULKs within 15 days, staking token — USDN. Farm 3 will farm rewards of 10,000 HULKs within 15 days, staking token — Token Y. Token Y will be announced prior to the farms’ launch. Genesis farming time will be 15 days, after that farming rate will be settled on the level of 15th day. We implement halving every three days, so early farmers will get more HULKs. View on Etherscan. In order to support the price of the token from dumping, we will take a 5% commission for the sale of tokens, when holders sell it on Uniswap, burn 4% and add 1% to the community grants account. The burnt amount will be added to farming pools after 15 days of initial farming. So, for example, if someone sold 20,000 HULKs, we will take 1,000 tokens, burn 800 of them and they will be re-minted on day 16. 200 tokens will be sent to the community grants address. The total supply is 100,000 tokens.”

The third step includes the staking pool. The staking pool will be open for everyone on the following terms and conditions.


Funds from the staking pool will be transferred to the HFT fund for trading operations.

Lastly, the Vault concept is descriptive. “We want to share revenue from HFT fund among HULK holders that stake their tokens in HULK Vault. HFT fund will send revenue from its operation once a month, on the first day of the following month. Current concept: Monthly revenue from HFT operations will be shared between HULK tokens staked in the vault according to the time of staking divided on 720 hours. Example: You stake your 500 HULK tokens in Vault for 20 days (480 hours). Your HULK/hours equal to 500*480=240,000. Total HULK/hours in Vault in this month — 60,000,000. Your share in this month = 0,4%. HFT fund has earned 4% on staking pool funds this month. After payout of their 1,25% (15%/12) per month to USDT stakers, the remaining part is 10,000,000 USDT x 2,75% = 275,000 USD. Your profit share 0.4% of 275,000 = 1100 USDT will be sent as USDT to your address, connected with a Vault.”

All of the above described by the tokens creators seems very complicated, but many tokens are already trying to accomplish this without access to an already built fund which can execute trades on a daily basis. Also due in part is the projects commitment to becoming a DAO by allowing holders to vote on key project decisions and development to make the ecosystem more effective and manageable. Decentralization is the most trustworthy base of contract/cryptocurrency ownership. It creates a unique and secure environment free from direct outside influence due to the filter of the entire community being involved. The developers have said that the voting system for the project will be done within the first 30 days of project launch.

With lofty ambition and high expectations, the project looks to capitalize on the DeFi boom by hedging their fund against the market and giving holders a share of the pie. It will be interesting to see how successful and sustainable the project can be, but we will find out soon enough.

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.

Why is it still not too late to start and continue mining Ethereum in 2020

There are two main theories about how ETH will develop further. One suggests that ETH is completely dependent on Bitcoin, it rises and falls along with it at the same time. The second theory argues that Ethereum may soon lose its altcoin status and become an independent cryptocurrency - according to researchers at the San Francisco Open Exchange (SFOX), for example.
Since the beginning of the year, ETH has risen in price by more than 34%, and this trend continues. Some experts expect the coin to rise to $400- $500 by the end of 2020, the most positive optimists expect it to reach $2,000 in the next year. And all because of the DeFi’s boom and the massive tokenization process, which became possible thanks to the Ethereum technology.
Foolproof Mining
Today, to start mining Ether, you do not need to undergo special training or be super tech-savvy. Forums have useful information for beginners. Mining equipment manufacturers are investing more and more money in creating the most productive and easy-to-use and energy-efficient hardware possible.
According to Technavio's calculations, the volume of the world market for mining equipment in 2019-2023 will grow by $2.7 billion. Users usually benefit from such a race, because when the opportunity to “show off technologies” ends, vendors begin to reduce prices for their solutions and offer special conditions.
As for software, it is better to mine on a specialized one and avoid unnecessary problems. For example, ethOS or CoinFly's COS copes well with high loads, manages mining processes of any scale and on any equipment through a single interface, automates routine and controls income and expenses.
Profit in Mining Pool
Great thing about mining in 2020 is that you can choose a convenient profitable pool that will regularly fill your virtual pockets with Ether and sleep peacefully, read about what to look for when choosing a pool here. The main thing is to understand which one brings more money. Take a look at the CoinFly pool, which according to independent tests’ giving well profit…
Hedge risks
Whenever you’re afraid of losing income due to price fluctuations, buy Put Options (on Binance, for example) oand short ETH futures.

My college essay on Bitcoin and computers. First Draft. Thought you all might like this.

I always thought computers were simple. At their fundamental level, they are just 1s and 0s. An invisible dance of yes’s and no’s running through a sheet of silicon at billions of times per second. Computers are amazing and unique machines that will forever be apart of our lives. Our sheer dependence on computers motivated me to research the topic? As my understanding of this concept grew, so did my curiosity. I started researching computers as much as I could. I would spend hours a day browsing Youtube and reading articles just to satisfy my interest. That’s why when my dad first brought up the topic of bitcoin during my freshman year, I wasn’t surprised to hear his enthusiasm. I had learned much about this currency over my couple years of research, but I knew very little about how to actually make money off it. He had been tracking the price for a few months and was considering buying a few, just to see what would happen. Little did either of us know; the price of this virtual coin would multiply nearly 30 times in just a few short months.
A few weeks passed and eventually he brought up the topic of buying bitcoin again. His initial interest inspired me to look more into currency and how it worked. I told my dad there was another way to make money off of bitcoins: Bitcoin miners. These impressive and powerful computers are precisely optimized to earn these coins, and I knew I could make one. I explained how this was my once in a lifetime opportunity, like how he explained to me that he missed out on investing in Apple in the 80s. “It could be a money-printing machine,” I joked. With our excitement peaked, we decided to split the $2,000 investment 50/50, and I started the buying process.
I started the process by buying the parts of the machine. I had learned that like Legos, a computer consists of simple components to make the whole. However, unlike an ordinary everyday computer, ours would have a concentrated task. Mining bitcoin is not a complicated process for a computer to do. In essence, by completing simple math problems as quickly as possible, a computer process’ bitcoin transactions from around the world and is rewarded in a tiny fraction of a coin. As more and more transactions take place, the higher the demand for processing, and the higher the reward.
I was lucky enough to know how to build the computer. However, what I was not prepared for was the constant troubleshooting and maintenance I would have to give to this project. Sometimes the computer would simply turn off randomly, sometimes a part was not detected, and other times it merely just ran at half its optimized rate. I learned how to fix issues where there was no logical reason for the problem. Like a calculator, I always thought a computer could never mess up. My hundreds of hours of troubleshooting and blind hope quickly changed my view. I put a vast amount of free time into the project, knowing that potential it had. After lots of hard work, long nights, and determination, I had finally completed my dream project.
I was proud of what I had created. The computer was placed in my room and was like a pet. The loud but rhythmic fans helped me fall asleep, and the heat kept me warm during the winter. From school, I would monitor the machine, and if it had run into an error, I would simply restart it from my phone. My plan was working, and in a little over half a year, our investment should turn into profit. In only a few months, we were already halfway to making our money back. We were lucky because the price of bitcoin itself had doubled since we started, going from nearly $10,000 to $20,000 in a few short months, but as I looked at my account, I had no bitcoin. A few days earlier, hackers had stolen $64 million dollars from the company I mined with.
I felt like a victim. I had done everything right. I built the computer perfectly, I managed everything, I put the time in, and I put the effort in. I was robbed, and I was discouraged. Forced with no other option, we restarted our operation. Bitcoin was still increasing in price, we thought, so there was no reason to stop now. Our operation had restarted and was going well, but for the first time since we started, the price of bitcoin was not doing so well. The bubble was about to burst. It began with my hack, which made national news and hurt the price. Although the price recovered in a few weeks, it was going down again, fast. Believing it would improve, my dad and I decided to hold and not sell. A month later, Bitcoin was back to $8,000 per coin. The fad was over, and we couldn’t even make a profit over our cost of electricity. Again, I was robbed. I did nothing wrong and still lost almost everything. I decided to put the computer in a box and wait a few months; however, the wait was worthless. The coin plateaued at about $10,000, and it simply was not sustainable to continue mining. A year later, we sold the computers for parts and managed to make back about half our initial investment. It was over.
I had lost over $1,000 and months of time and effort. However, as I moved on and started to reflect on the experience, I was the winner. I learned so much about computers and how they operate. In the end, I had learned many skills, from patience and compassion to planning and researching. I had learned not only to build a computer but to manage systems and multitask. I learned countless lessons and gained essential and unique skills that I hope will carry me throughout life. This unique experience has taught me to always keep trying at what I believe in. There’s always an award for doing whatever I think is right. I hope to bring these beliefs and lessons with me throughout life, as I learn and grow from what I was taught. Whenever people ask me what computers are, I always laugh and explain how a computer is just a bunch of simple lego bricks working together to do complicated tasks. However, inside I still have trouble answering this simple question. It is merely just parts working together, but a computer is so much more complicated and beautiful than that. Honestly, I still don’t understand them.

My traiding work space

My traiding work space
In this article I will just show you my workspace, how I work, and how it all looks. As I wrote earlier, there is manual and automated trading. For robots, of course, everything is simple: create it, launch it and the robot is ready to trade. Of course, from time to time I make sure that there are no surprises, bugs and problems. Initially, people think that after creating a robot, you can start it up and forget about it. But in fact, in trading, it is important to have everything in the field of attention: experience shows that otherwise you can get unpleasant losses (although there are sometimes pleasant random profits, but still losses are more often). A few examples below:

Okex spot BTCUSDT
Here is an example of a work area on the Okex spot BTCUSDT, where the purple histograms are for a cluster (volumetric) market analysis, on the basis of which I consider trading points within a day (for example, at the time of writing this article, it is assumed that a buy trade will be opened, with an exit at a price closer to 10750). The next example: the MOEX exchange, RTSI futures. The robot is working.

Rim0 on Micex
At the moment, the robot is out of position. There was a very effective short position, after which the algorithm is looking for new entry points. The same algorithm works with Bitcoin, as well as with the S&P500 futures.

BTC on Binance futures
Everything is simple and clear, the red arrow is a short position, the green one is a long one. At the moment, a short position on the Bitcoin market at a price close to 12000 is opened. The robot has no targets, and it does not assume where to close, and despite the profitability of the current transaction, it can also close at a loss (who knows, but I hope not!))). The same pattern works on the esm0 market

Esm0
Unfortunately, the profit is calculated only in absolute terms (entry price - exit price = profit). In fact, 1 step of the price for esm0 costs $12.5, and therefore the actual profit is not $37, but $1850. These are just initial examples so that you can have an idea of what I am doing. In future articles, I will talk about the analysis methods that I have already used. If you have any questions, write me, I'm always glad to talk!!

EOS, and COMP have been doing really well, so they might be worth keeping. This is just a really good promotion, probably one of the better i’ve see. Its easy AF, quick, and the reward is really good. If you don’t know anything about crypto, i highly suggest you learn. It’s still very early and its growing super quick. cryptocurrency has gained a ton of attention in the past couple years and is actually starting to become a real actual currencies (already is, but according to our governments) many different types of crypto is starting to become accepted in a bunch of stores, realtors are taking as payment for a house, and colleges are even accepting as tuition. I started researching bitcoin a short amount of time after Satoshi Nakamoto released it (2009) and bought my first few in 2013 at 15$!! From early 2013 the price was about $11 USD and at the end of 2017, $20,000. But they fell and recovered as the stock market does. But the 24-hour trading Volume today, in 2020 is is INSANE ($20,690,383,231) with an even crazier market cap of $209,783,036,693, which by the middle-end of next month should reach $210 billion, possibly sooner. Its just a really smart investment, buy a little over time. Some analysts are predicting that BTC could reach anywhere from $100k to $1,000,000 for BTC in the next few years. Im not sure exactly where i would name the price in 5 years, but know there is only a limited supply of BTC. They are mined (basically just means that the transactions and blocks on the ledger or blockchain are verified) by sophisticated pieces of hardware called ASIIC miners, or some even use GPU, and CPU in expensive computers. Although CPU mining can be very inefficient anymore as the mathematical calculations and problems the miners need to solve get more and more complicated over time. This, the limited supply, the increasing interest, usability, and need for blockchain technology all add the the idea of BTC reaching such incredibly high futures. Their is a total of 20,999,976 bitcoin and that is it. With a total of 18,517,418.75 in circulation. The last BTC is estimated to be 2140. Big difference from the 18.5M mined in 10 years, right? Thats because of the halving. Anyway, I’m sure you have heard some things about BTC, probably from the media, and if it was, it probably wasn’t good. You probably heard that people buy illegal dangerous stuff off of the “Darknet” and that its completely untraceable. Or that money can be laundered through BTC. But that is hardly partly true for BTC and other cryptocurrencies, and completely true for the USD. While the blockchain doesn’t include any personal information connected to wallets (unless you want it there, or you have the wallet through a service that makes you use personal information, which many services are doing), all transactions can still be tracked and seen by anyone who has an internet connection at https://www.blockchain.com. So if the identity of one of the wallet addresses is known, it would be easier to figure the other out. But for paper, money that cannot be said... completely untraceable, has been prone to money laundering since it’s inception, can be used to purchase various drugs—hookers, guns, dynamite, and even politicians... since its inception, without a trace. The reason not just bitcoin, but i think even more exciting, is just blockchain technology and a host of things that are coming with it. It can be used for tons of things, software and can be built directly into blockchains, they can hold and process data at enormous speeds, while being extremely, extremely secure. More secure in a lot ways than banks. There are tons of new cryptocurrency projects being started everyday. For the most part, all of these projects have some sort of token integrated, because its what powers, and processes the data. If people find the project interesting or a great idea you like you’ll be able to invest in it buy buying/selling, or holding the token/coin. When these projects gain enough traction by like-minded individuals, the coin gains a value. This value can then be exchanged for other crypto, or traded directly for Fiat currencies ($,€,₽,¥,£,₩). For some examples of how wonderful the community is, and reveal what the true nature of blockchain and crypto was founded on, ill list 3 of my favorite crypto projects of 2020 so far along with a little excerpt from the white paper or other:
  1. AIDCOIN: “allows websites to embed a widget into their website and accept donations in any cryptocurrency. Any donated crypto is transferred into AID token, which is also a stable coin. At first, this might seem like not such a good thing but the more I looked into it, the more I realized accepting a stable coin might actually make more sense for a charity as it reduces their risk exposure to volatility.”
  2. BRAVE BROWSER—Privacy Internet Browser: “As far as I’m concerned, keeping people safe and protecting their privacy and security is a noble endeavor. For far too long, giants like Google and Facebook have gotten away with unethical data practices with nothing more than a slap on the wrist. They have been able to spy on their users, abuse their data and use it for whatever purpose they deem fit. Brave Browser is looking to put an end to that through the most secure browser that exists on the market today.” Basically Brave takes on the responsibility of completely protecting privacy and from ads. As an added available option, brave allows you, to watch and look at sponsored ads while you browse. So basically just a stand-in for other browsers ads, but instead you make money WITH brave. You are awarded BAT (Basic Attention Token) for your service. BAT’s are currently at .21¢.
  3. Power Ledger: Last but not least. Power Ledger is probably one of my favorite projects that is actually making a real use-case out of crypto and blockchain. They are aiming to disrupt the energy sector with a heightened focus on renewable energy. Their software allows for three core things: 1. Energy Trading (if you have excess energy from your solar panels, for example, you can trade that to your neighbor through Power Ledger). 2. Environmental commodities trading (to help for the reliable tracking of renewable energy credits). 3. Renewable asset ownership (This will allow people who cannot afford their own renewable energy set-up to invest in fractional ownership). I honestly think Power Ledger is doing God’s work and wish them all the best.
As those projects above outlined, the basic principles behind pretty much every currency and upcoming project i have ever seen is, Trust, Sharing profit with the users who help make it into what it becomes, actual transparency, no central authority (due to decentralization), and lastly i believe it gives opportunity to those who are out if opportunity’s way. This is because it reaches so far, like into oppressive governments and 3rd work countries. Anyways, i hope to have given you a little insight during this read. Crypto has so much potential to fill and has already done so much. Looking forward to seeing where else all of this goes.

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.

Hulk.Finance: A Combination of DeFi and High Frequency Trading

Hulk.Finance: A Combination of DeFi and High Frequency Trading
DeFi continues to push the limits of blockchain technology. Whether its staking a native token for a second token from the same ecosystem, locking liquidity for an eternity to promote liquidity providing and the benefits of locking tokens, or simply creating new tokenomics that can be tested and studied, DeFi is exploring all avenues to produce the next breakout token such as YFI. Hulk.finance has stepped in to do just that.

https://preview.redd.it/f4mrjlxu5ct51.png?width=675&format=png&auto=webp&s=2c2d11429ae554d541bed3a19955fed71e6f9b6d
Hulk.finance (Contract Address: 0xE1f8CD01aB04b51d02C6fb2BCA61B03fB5e33B99) is an ERC20 token which plans to utilize a DAO (Decentralized Autonomous Organization) format that will be community governed in order to promote high frequency trading in a manner only DeFi can bring to the table. As stated on their website, “Our project connects a high-yield partner HFT (High Frequency Trading) fund that has successfully worked from the beginning of 2020 and has year-to-date yields of more than 40%. The fund size is more than 70 millions USD and they operate on several cryptocurrency exchanges like Binance and Bithumb with their API robots. What is good — automated trading does not require continuous uptrend of the Bitcoin price. We have seen good results during Bitcoin breakouts and breakdowns. We want to have the same yields from our investments. But there is a problem — they work with an entrance barrier of 1,000,000 USDT, like many private banking services or high-yield ETFs. Our basic idea is to make a kind of DeFi staking pool and put it under the management of the HFT fund. We will develop all infrastructure for connecting finance flows, deposits, and withdrawals.

https://preview.redd.it/fugnjuoz5ct51.png?width=717&format=png&auto=webp&s=2aa5bd3828b4803191de330f024edab277f47906

The HULK total supply is 100,000 Tokens. Distribution breakdown is as follows:
  • Farms Distribution: 80,000 (6% or 4,800 — Team Part)
  • Pre-sale: 10,000
  • Initial Liquidity Pool: 8,000
  • Development: 1,000
  • Marketing: 1,000

https://preview.redd.it/js0zqx136ct51.png?width=717&format=png&auto=webp&s=0469468caa8d47be95baf392b2a26a9303d7f773
The project is new but already has a road-map to help guide their lofty ambitions. The first step begins with the formation of the pre-sale and Liquidity pool on Uniswap which is currently ongoing. Secondly, they will distribute Hulk tokens via staking farms. As described in their website they “will run staking farms for farming 80,000 HULKs. You will need to stake appropriate tokens on the selected farms to get your share of rewards in HULKs. Farm 1 will farm rewards of 60,000 HULKs within 15 days, staking token — ETH-HULK LP Uniswap V2. Farm 2 will farm rewards of 10,000 HULKs within 15 days, staking token — USDN. Farm 3 will farm rewards of 10,000 HULKs within 15 days, staking token — Token Y. Token Y will be announced prior to the farms’ launch. Genesis farming time will be 15 days, after that farming rate will be settled on the level of 15th day. We implement halving every three days, so early farmers will get more HULKs. View on Etherscan. In order to support the price of the token from dumping, we will take a 5% commission for the sale of tokens, when holders sell it on Uniswap, burn 4% and add 1% to the community grants account. The burnt amount will be added to farming pools after 15 days of initial farming. So, for example, if someone sold 20,000 HULKs, we will take 1,000 tokens, burn 800 of them and they will be re-minted on day 16. 200 tokens will be sent to the community grants address. The total supply is 100,000 tokens.

The third step includes the staking pool. The staking pool will be open for everyone on the following terms and conditions.

  • Staking Pool 1 Target: 10 million USDT.
  • Guaranteed APY: 15%.
  • Minimum Staking Amount: 100 USDT.
  • Type Of Staking: Locked
  • Minimum Staking Term: 24 hours
  • Withdraw Period: 24 hours after withdrawal order.
  • Reward Calculation: daily.
Funds from the staking pool will be transferred to the HFT fund for trading operations.

Lastly, the Vault concept is descriptive. “We want to share revenue from HFT fund among HULK holders that stake their tokens in HULK Vault. HFT fund will send revenue from its operation once a month, on the first day of the following month. Current concept: Monthly revenue from HFT operations will be shared between HULK tokens staked in the vault according to the time of staking divided on 720 hours. Example: You stake your 500 HULK tokens in Vault for 20 days (480 hours). Your HULK/hours equal to 500\480=240,000. Total* HULK/hours in Vault in this month — 60,000,000. Your share in this month = 0,4%. HFT fund has earned 4% on staking pool funds this month. After payout of their 1,25% (15%/12) per month to USDT stakers, the remaining part is 10,000,000 USDT x 2,75% = 275,000 USD. Your profit share 0.4% of 275,000 = 1100 USDT will be sent as USDT to your address, connected with a Vault.”

All of the above described by the tokens creators seems very complicated, but many tokens are already trying to accomplish this without access to an already built fund which can execute trades on a daily basis. Also due in part is the projects commitment to becoming a DAO by allowing holders to vote on key project decisions and development to make the ecosystem more effective and manageable. Decentralization is the most trustworthy base of contract/cryptocurrency ownership. It creates a unique and secure environment free from direct outside influence due to the filter of the entire community being involved. The developers have said that the voting system for the project will be done within the first 30 days of project launch.

With lofty ambition and high expectations, the project looks to capitalize on the DeFi boom by hedging their fund against the market and giving holders a share of the pie. It will be interesting to see how successful and sustainable the project can be, but we will find out soon enough.

EOS, and COMP have been doing really well, so they might be worth keeping. This is just a really good promotion, probably one of the better i’ve see. Its easy AF, quick, and the reward is really good. If you don’t know anything about crypto, i highly suggest you learn. It’s still very early and its growing super quick. cryptocurrency has gained a ton of attention in the past couple years and is actually starting to become a real actual currencies (already is, but according to our governments) many different types of crypto is starting to become accepted in a bunch of stores, realtors are taking as payment for a house, and colleges are even accepting as tuition. I started researching bitcoin a short amount of time after Satoshi Nakamoto released it (2009) and bought my first few in 2013 at 15$!! From early 2013 the price was about $11 USD and at the end of 2017, $20,000. But they fell and recovered as the stock market does. But the 24-hour trading Volume today, in 2020 is is INSANE ($20,690,383,231) with an even crazier market cap of $209,783,036,693, which by the middle-end of next month should reach $210 billion, possibly sooner. Its just a really smart investment, buy a little over time. Some analysts are predicting that BTC could reach anywhere from $100k to $1,000,000 for BTC in the next few years. Im not sure exactly where i would name the price in 5 years, but know there is only a limited supply of BTC. They are mined (basically just means that the transactions and blocks on the ledger or blockchain are verified) by sophisticated pieces of hardware called ASIIC miners, or some even use GPU, and CPU in expensive computers. Although CPU mining can be very inefficient anymore as the mathematical calculations and problems the miners need to solve get more and more complicated over time. This, the limited supply, the increasing interest, usability, and need for blockchain technology all add the the idea of BTC reaching such incredibly high futures. Their is a total of 20,999,976 bitcoin and that is it. With a total of 18,517,418.75 in circulation. The last BTC is estimated to be 2140. Big difference from the 18.5M mined in 10 years, right? Thats because of the halving. Anyway, I’m sure you have heard some things about BTC, probably from the media, and if it was, it probably wasn’t good. You probably heard that people buy illegal dangerous stuff off of the “Darknet” and that its completely untraceable. Or that money can be laundered through BTC. But that is hardly partly true for BTC and other cryptocurrencies, and completely true for the USD. While the blockchain doesn’t include any personal information connected to wallets (unless you want it there, or you have the wallet through a service that makes you use personal information, which many services are doing), all transactions can still be tracked and seen by anyone who has an internet connection at https://www.blockchain.com. So if the identity of one of the wallet addresses is known, it would be easier to figure the other out. But for paper, money that cannot be said... completely untraceable, has been prone to money laundering since it’s inception, can be used to purchase various drugs—hookers, guns, dynamite, and even politicians... since its inception, without a trace. The reason not just bitcoin, but i think even more exciting, is just blockchain technology and a host of things that are coming with it. It can be used for tons of things, software and can be built directly into blockchains, they can hold and process data at enormous speeds, while being extremely, extremely secure. More secure in a lot ways than banks. There are tons of new cryptocurrency projects being started everyday. For the most part, all of these projects have some sort of token integrated, because its what powers, and processes the data. If people find the project interesting or a great idea you like you’ll be able to invest in it buy buying/selling, or holding the token/coin. When these projects gain enough traction by like-minded individuals, the coin gains a value. This value can then be exchanged for other crypto, or traded directly for Fiat currencies ($,€,₽,¥,£,₩). For some examples of how wonderful the community is, and reveal what the true nature of blockchain and crypto was founded on, ill list 3 of my favorite crypto projects of 2020 so far along with a little excerpt from the white paper or other:
  1. AIDCOIN: “allows websites to embed a widget into their website and accept donations in any cryptocurrency. Any donated crypto is transferred into AID token, which is also a stable coin. At first, this might seem like not such a good thing but the more I looked into it, the more I realized accepting a stable coin might actually make more sense for a charity as it reduces their risk exposure to volatility.”
  2. BRAVE BROWSER—Privacy Internet Browser: “As far as I’m concerned, keeping people safe and protecting their privacy and security is a noble endeavor. For far too long, giants like Google and Facebook have gotten away with unethical data practices with nothing more than a slap on the wrist. They have been able to spy on their users, abuse their data and use it for whatever purpose they deem fit. Brave Browser is looking to put an end to that through the most secure browser that exists on the market today.” Basically Brave takes on the responsibility of completely protecting privacy and from ads. As an added available option, brave allows you, to watch and look at sponsored ads while you browse. So basically just a stand-in for other browsers ads, but instead you make money WITH brave. You are awarded BAT (Basic Attention Token) for your service. BAT’s are currently at .21¢.
  3. Power Ledger: Last but not least. Power Ledger is probably one of my favorite projects that is actually making a real use-case out of crypto and blockchain. They are aiming to disrupt the energy sector with a heightened focus on renewable energy. Their software allows for three core things: 1. Energy Trading (if you have excess energy from your solar panels, for example, you can trade that to your neighbor through Power Ledger). 2. Environmental commodities trading (to help for the reliable tracking of renewable energy credits). 3. Renewable asset ownership (This will allow people who cannot afford their own renewable energy set-up to invest in fractional ownership). I honestly think Power Ledger is doing God’s work and wish them all the best.
As those projects above outlined, the basic principles behind pretty much every currency and upcoming project i have ever seen is, Trust, Sharing profit with the users who help make it into what it becomes, actual transparency, no central authority (due to decentralization), and lastly i believe it gives opportunity to those who are out if opportunity’s way. This is because it reaches so far, like into oppressive governments and 3rd work countries. Anyways, i hope to have given you a little insight during this read. Crypto has so much potential to fill and has already done so much. Looking forward to seeing where else all of this goes.

Spot or Margin Trading?

Spot or Margin Trading?

Spot Trading

This type of trading occurs in the spot market at the current price. When you are engaged in spot trading, you make a deal at an affordable bid and ask price, which is requested by other market participants. To complete a trade, you need to have available assets to pay for the trade by the settlement date.
For example, if you are going to make a purchase of BTC in the amount of $1,500, then you must make a deposit by the date of settlement of at least the specified amount. Usually the date is calculated according to the T + 2 trading day scheme. Otherwise, the exchange will refuse to enter the Bitcoin position.

https://preview.redd.it/tvytmqrptnp51.png?width=700&format=png&auto=webp&s=b0527f8994f4aff3477c5e9484c6c0254e97f2c2

Margin Trading

With margin trading, you borrow funds from a third party to increase your position. Margin and spot trading are different. With margin trading, you do not need the full amount of the transaction to open a position, you just need to have assets that will be on the margin of the position you are going to open.
For example, you are going to buy BTC for $1000. Some platforms are ready to provide you with up to 100x leverage. That is, you only need $10 on your account to trade Bitcoin for $1,000 BTC.
To keep a position open, you only need to hold 1% (with 100x leverage) of the contract amount. Depending on the course of the trade, you can open even more positions or withdraw profits.

What to choose?

Spot Trading: benefits

  1. Management of risks: trading occurs only with your own balance, which you actually own, that is, the impossibility of going into a negative.
  2. Guarantee: spot trading takes place only on own assets. In this way, the exchange ensures that you avoid over-leveraging.

Spot Trading: limitations

  1. Missed trading opportunities: even with confidence in the deal, you will not be able to earn 100% or more, you will only be able to earn the amount that your capital allows.

Margin Trading: benefits

  1. Possibility of increasing profits: the presence of leverage allows you to increase your trade up to 100 times in comparison with your capital.
  2. Low-frequency trading: an increased likelihood of trades identified in this type of trading.

Margin Trading: limitations

  1. Risks: Opportunity to lose more money than the initial investment.
  2. Liquidation: complete liquidation of a position with insufficient funds to cover losses.

What strategy should you follow?

It all depends on your usual trading style and your character: are you tolerant of risks, what knowledge about investing you have.
Choose the strategies that are right for you.

Also due in part is the projects commitment to becoming a DAO by allowing holders to vote on key project decisions and development to make the ecosystem more effective and manageable. Decentralization is the most trustworthy base of contract/cryptocurrency ownership. It creates a unique and secure environment free from direct outside influence due to the filter of the entire community being involved. The developers have said that the voting system for the project will be done within the first 30 days of project launch.

With lofty ambition and high expectations, the project looks to capitalize on the DeFi boom by hedging their fund against the market and giving holders a share of the pie. It will be interesting to see how successful and sustainable the project can be, but we will find out soon enough.

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.
