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:

Source Code

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

Scaling

How it works & scales

Architectural Scaling

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

Economic Scaling

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

Scaled Deployment

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

Flexibility in Scaling

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

Cost

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

Getting Started

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

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

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

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

Costs and resources

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

Requirements

Scaling

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

Decentralization

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

Usability Scaling solutions should have a simple end user experience.

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

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

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

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

Bonus Points

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

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

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

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

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

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

Bonus

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

TIME

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

Dragon Den

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

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

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

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

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

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

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

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

Other Considerations

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

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

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

Conclusion

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

Disney Releases Blockchain Platform as Open Source

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

Open Source

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

How To End The Cryptocurrency Exchange "Wild West" Without Crippling Innovation


In case you haven't noticed the consultation paper, staff notice, and report on Quadriga, regulators are now clamping down on Canadian cryptocurrency exchanges. The OSC and other regulatory bodies are still interested in industry feedback. They have not put forward any official regulation yet. Below are some ideas/insights and a proposed framework.



Many of you have limited time to read the full proposal, so here are the highlights:

Offline Multi-Signature

Effective standards to prevent both internal and external theft. Exchange operators are trained and certified, and have a legal responsibility to users.

Regular Transparent Audits

Provides visibility to Canadians that their funds are fully backed on the exchange, while protecting privacy and sensitive platform information.

Insurance Requirements

Establishment of basic insurance standards/strategy, to expand over time. Removing risk to exchange users of any hot wallet theft.


Background and Justifications


Cold Storage Custody/Management
After reviewing close to 100 cases, all thefts tend to break down into more or less the same set of problems:
• Funds stored online or in a smart contract,
• Access controlled by one person or one system,
• 51% attacks (rare),
• Funds sent to the wrong address (also rare), or
• Some combination of the above.
For the first two cases, practical solutions exist and are widely implemented on exchanges already. Offline multi-signature solutions are already industry standard. No cases studied found an external theft or exit scam involving an offline multi-signature wallet implementation. Security can be further improved through minimum numbers of signatories, background checks, providing autonomy and legal protections to each signatory, establishing best practices, and a training/certification program.
The last two transaction risks occur more rarely, and have never resulted in a loss affecting the actual users of the exchange. In all cases to date where operators made the mistake, they've been fully covered by the exchange platforms.
• 51% attacks generally only occur on blockchains with less security. The most prominent cases have been Bitcoin Gold and Ethereum Classic. The simple solution is to enforce deposit limits and block delays such that a 51% attack is not cost-effective.
• The risk of transactions to incorrect addresses can be eliminated by a simple test transaction policy on large transactions. By sending a small amount of funds prior to any large withdrawals/transfers as a standard practice, the accuracy of the wallet address can be validated.
The proposal covers all loss cases and goes beyond, while avoiding significant additional costs, risks, and limitations which may be associated with other frameworks like SOC II.

On The Subject of Third Party Custodians
Many Canadian platforms are currently experimenting with third party custody. From the standpoint of the exchange operator, they can liberate themselves from some responsibility of custody, passing that off to someone else. For regulators, it puts crypto in similar categorization to oil, gold, and other commodities, with some common standards. Platform users would likely feel greater confidence if the custodian was a brand they recognized. If the custodian was knowledgeable and had a decent team that employed multi-sig, they could keep assets safe from internal theft. With the right protections in place, this could be a great solution for many exchanges, particularly those that lack the relevant experience or human resources for their own custody systems.
However, this system is vulnerable to anyone able to impersonate the exchange operators. You may have a situation where different employees who don't know each other that well are interacting between different companies (both the custodian and all their customers which presumably isn't just one exchange). A case study of what can go wrong in this type of environment might be Bitpay, where the CEO was tricked out of 5000 bitcoins over 3 separate payments by a series of emails sent legitimately from a breached computer of another company CEO. It's also still vulnerable to the platform being compromised, as in the really large $70M Bitfinex hack, where the third party Bitgo held one key in a multi-sig wallet. The hacker simply authorized the withdrawal using the same credentials as Bitfinex (requesting Bitgo to sign multiple withdrawal transactions). This succeeded even with the use of multi-sig and two heavily security-focused companies, due to the lack of human oversight (basically, hot wallet). Of course, you can learn from these cases and improve the security, but so can hackers improve their deception and at the end of the day, both of these would have been stopped by the much simpler solution of a qualified team who knew each other and employed multi-sig with properly protected keys. It's pretty hard to beat a human being who knows the business and the typical customer behaviour (or even knows their customers personally) at spotting fraud, and the proposed multi-sig means any hacker has to get through the scrutiny of 3 (or more) separate people, all of whom would have proper training including historical case studies.
There are strong arguments both for and against using use of third party custodians. The proposal sets mandatory minimum custody standards would apply regardless if the cold wallet signatories are exchange operators, independent custodians, or a mix of both.

On The Subject Of Insurance
ShakePay has taken the first steps into this new realm (congratulations). There is no question that crypto users could be better protected by the right insurance policies, and it certainly feels better to transact with insured platforms. The steps required to obtain insurance generally place attention in valuable security areas, and in this case included a review from CipherTrace. One of the key solutions in traditional finance comes from insurance from entities such as the CDIC.
However, historically, there wasn't found any actual insurance payout to any cryptocurrency exchange, and there are notable cases where insurance has not paid. With Bitpay, for example, the insurance agent refused because the issue happened to the third party CEO's computer instead of anything to do with Bitpay itself. With the Youbit exchange in South Korea, their insurance claim was denied, and the exchange ultimately ended up instead going bankrupt with all user's funds lost. To quote Matt Johnson in the original Lloyd's article: “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.”
ShakePay's insurance was only reported to cover their cold storage, and “physical theft of the media where the private keys are held”. Physical theft has never, in the history of cryptocurrency exchange cases reviewed, been reported as the cause of loss. From the limited information of the article, ShakePay made it clear their funds are in the hands of a single US custodian, and at least part of their security strategy is to "decline[] to confirm the custodian’s name on the record". While this prevents scrutiny of the custodian, it's pretty silly to speculate that a reasonably competent hacking group couldn't determine who the custodian is. A far more common infiltration strategy historically would be social engineering, which has succeeded repeatedly. A hacker could trick their way into ShakePay's systems and request a fraudulent withdrawal, impersonate ShakePay and request the custodian to move funds, or socially engineer their way into the custodian to initiate the withdrawal of multiple accounts (a payout much larger than ShakePay) exploiting the standard procedures (for example, fraudulently initiating or override the wallet addresses of a real transfer). In each case, nothing was physically stolen and the loss is therefore not covered by insurance.
In order for any insurance to be effective, clear policies have to be established about what needs to be covered. Anything short of that gives Canadians false confidence that they are protected when they aren't in any meaningful way. At this time, the third party insurance market does not appear to provide adequate options or coverage, and effort is necessary to standardize custody standards, which is a likely first step in ultimately setting up an insurance framework.
A better solution compared to third party insurance providers might be for Canadian exchange operators to create their own collective insurance fund, or a specific federal organization similar to the CDIC. Such an organization would have a greater interest or obligation in paying out actual cases, and that would be it's purpose rather than maximizing it's own profit. This would be similar to the SAFU which Binance has launched, except it would cover multiple exchanges. There is little question whether the SAFU would pay out given a breach of Binance, and a similar argument could be made for a insurance fund managed by a collective of exchange operators or a government organization. While a third party insurance provider has the strong market incentive to provide the absolute minimum coverage and no market incentive to payout, an entity managed by exchange operators would have incentive to protect the reputation of exchange operators/the industry, and the government should have the interest of protecting Canadians.

On The Subject of Fractional Reserve
There is a long history of fractional reserve failures, from the first banks in ancient times, through the great depression (where hundreds of fractional reserve banks failed), right through to the 2008 banking collapse referenced in the first bitcoin block. The fractional reserve system allows banks to multiply the money supply far beyond the actual cash (or other assets) in existence, backed only by a system of debt obligations of others. Safely supporting a fractional reserve system is a topic of far greater complexity than can be addressed by a simple policy, and when it comes to cryptocurrency, there is presently no entity reasonably able to bail anyone out in the event of failure. Therefore, this framework is addressed around entities that aim to maintain 100% backing of funds.
There may be some firms that desire but have failed to maintain 100% backing. In this case, there are multiple solutions, including outside investment, merging with other exchanges, or enforcing a gradual restoration plan. All of these solutions are typically far better than shutting down the exchange, and there are multiple cases where they've been used successfully in the past.

Proof of Reserves/Transparency/Accountability
Canadians need to have visibility into the backing on an ongoing basis.
The best solution for crypto-assets is a Proof of Reserve. Such ideas go back all the way to 2013, before even Mt. Gox. However, no Canadian exchange has yet implemented such a system, and only a few international exchanges (CoinFloor in the UK being an example) have. Many firms like Kraken, BitBuy, and now ShakePay use the Proof of Reserve term to refer to lesser proofs which do not actually cryptographically prove the full backing of all user assets on the blockchain. In order for a Proof of Reserve to be effective, it must actually be a complete proof, and it needs to be understood by the public that is expected to use it. Many firms have expressed reservations about the level of transparency required in a complete Proof of Reserve (for example Kraken here). While a complete Proof of Reserves should be encouraged, and there are some solutions in the works (ie TxQuick), this is unlikely to be suitable universally for all exchange operators and users.
Given the limitations, and that firms also manage fiat assets, a more traditional audit process makes more sense. Some Canadian exchanges (CoinSquare, CoinBerry) have already subjected themselves to annual audits. However, these results are not presently shared publicly, and there is no guarantee over the process including all user assets or the integrity and independence of the auditor. The auditor has been typically not known, and in some cases, the identity of the auditor is protected by a NDA. Only in one case (BitBuy) was an actual report generated and publicly shared. There has been no attempt made to validate that user accounts provided during these audits have been complete or accurate. A fraudulent fractional exchange, or one which had suffered a breach they were unwilling to publicly accept (see CoinBene), could easily maintain a second set of books for auditors or simply exclude key accounts to pass an individual audit.
The proposed solution would see a reporting standard which includes at a minimum - percentage of backing for each asset relative to account balances and the nature of how those assets are stored, with ownership proven by the auditor. The auditor would also publicly provide a "hash list", which they independently generate from the accounts provided by the exchange. Every exchange user can then check their information against this public "hash list". A hash is a one-way form of encryption, which fully protects the private information, yet allows anyone who knows that information already to validate that it was included. Less experienced users can take advantage of public tools to calculate the hash from their information (provided by the exchange), and thus have certainty that the auditor received their full balance information. Easy instructions can be provided.
Auditors should be impartial, their identities and process public, and they should be rotated so that the same auditor is never used twice in a row. Balancing the cost of auditing against the needs for regular updates, a 6 month cycle likely makes the most sense.

Hot Wallet Management
The best solution for hot wallets is not to use them. CoinBerry reportedly uses multi-sig on all withdrawals, and Bitmex is an international example known for their structure devoid of hot wallets.
However, many platforms and customers desire fast withdrawal processes, and human validation has a cost of time and delay in this process.
A model of self-insurance or separate funds for hot wallets may be used in these cases. Under this model, a platform still has 100% of their client balance in cold storage and holds additional funds in hot wallets for quick withdrawal. Thus, the risk of those hot wallets is 100% on exchange operators and not affecting the exchange users. Since most platforms typically only have 1%-5% in hot wallets at any given time, it shouldn't be unreasonable to build/maintain these additional reserves over time using exchange fees or additional investment. Larger withdrawals would still be handled at regular intervals from the cold storage.
Hot wallet risks have historically posed a large risk and there is no established standard to guarantee secure hot wallets. When the government of South Korea dispatched security inspections to multiple exchanges, the results were still that 3 of them got hacked after the inspections. If standards develop such that an organization in the market is willing to insure the hot wallets, this could provide an acceptable alternative. Another option may be for multiple exchange operators to pool funds aside for a hot wallet insurance fund. Comprehensive coverage standards must be established and maintained for all hot wallet balances to make sure Canadians are adequately protected.

Current Draft Proposal

(1) Proper multi-signature cold wallet storage.
(a) Each private key is the personal and legal responsibility of one person - the “signatory”. Signatories have special rights and responsibilities to protect user assets. Signatories are trained and certified through a course covering (1) past hacking and fraud cases, (2) proper and secure key generation, and (3) proper safekeeping of private keys. All private keys must be generated and stored 100% offline by the signatory. If even one private keys is ever breached or suspected to be breached, the wallet must be regenerated and all funds relocated to a new wallet.
(b) All signatories must be separate background-checked individuals free of past criminal conviction. Canadians should have a right to know who holds their funds. All signing of transactions must take place with all signatories on Canadian soil or on the soil of a country with a solid legal system which agrees to uphold and support these rules (from an established white-list of countries which expands over time).
(c) 3-5 independent signatures are required for any withdrawal. There must be 1-3 spare signatories, and a maximum of 7 total signatories. The following are all valid combinations: 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.
(d) A security audit should be conducted to validate the cold wallet is set up correctly and provide any additional pertinent information. The primary purpose is to ensure that all signatories are acting independently and using best practices for private key storage. A report summarizing all steps taken and who did the audit will be made public. Canadians must be able to validate the right measures are in place to protect their funds.
(e) There is a simple approval process if signatories wish to visit any country outside Canada, with a potential whitelist of exempt countries. At most 2 signatories can be outside of aligned jurisdiction at any given time. All exchanges would be required to keep a compliant cold wallet for Canadian funds and have a Canadian office if they wish to serve Canadian customers.
(2) Regular and transparent solvency audits.
(a) An audit must be conducted at founding, after 3 months of operation, and at least once every 6 months to compare customer balances against all stored cryptocurrency and fiat balances. The auditor must be known, independent, and never the same twice in a row.
(b) An audit report will be published featuring the steps conducted in a readable format. This should be made available to all Canadians on the exchange website and on a government website. The report must include what percentage of each customer asset is backed on the exchange, and how those funds are stored.
(c) The auditor will independently produce a hash of each customer's identifying information and balance as they perform the audit. This will be made publicly available on the exchange and government website, along with simplified instructions that each customer can use to verify that their balance was included in the audit process.
(d) The audit needs to include a proof of ownership for any cryptocurrency wallets included. A satoshi test (spending a small amount) or partially signed transaction both qualify.
(e) Any platform without 100% reserves should be assessed on a regular basis by a government or industry watchdog. This entity should work to prevent any further drop, support any private investor to come in, or facilitate a merger so that 100% backing can be obtained as soon as possible.
(3) Protections for hot wallets and transactions.
(a) A standardized list of approved coins and procedures will be established to constitute valid cold storage wallets. Where a multi-sig process is not natively available, efforts will be undertaken to establish a suitable and stable smart contract standard. This list will be expanded and improved over time. Coins and procedures not on the list are considered hot wallets.
(b) Hot wallets can be backed by additional funds in cold storage or an acceptable third-party insurance provider with a comprehensive coverage policy.
(c) Exchanges are required to cover the full balance of all user funds as denominated in the same currency, or double the balance as denominated in bitcoin or CAD using an established trading rate. If the balance is ever insufficient due to market movements, the firm must rectify this within 24 hours by moving assets to cold storage or increasing insurance coverage.
(d) Any large transactions (above a set threshold) from cold storage to any new wallet addresses (not previously transacted with) must be tested with a smaller transaction first. Deposits of cryptocurrency must be limited to prevent economic 51% attacks. Any issues are to be covered by the exchange.
(e) Exchange platforms must provide suitable authentication for users, including making available approved forms of two-factor authentication. SMS-based authentication is not to be supported. Withdrawals must be blocked for 48 hours in the event of any account password change. Disputes on the negligence of exchanges should be governed by case law.

Steps Forward

Continued review of existing OSC feedback is still underway. More feedback and opinions on the framework and ideas as presented here are extremely valuable. The above is a draft and not finalized.
The process of further developing and bringing a suitable framework to protect Canadians will require the support of exchange operators, legal experts, and many others in the community. The costs of not doing such are tremendous. A large and convoluted framework, one based on flawed ideas or implementation, or one which fails to properly safeguard Canadians is not just extremely expensive and risky for all Canadians, severely limiting to the credibility and reputation of the industry, but an existential risk to many exchanges.
The responsibility falls to all of us to provide our insight and make our opinions heard on this critical matter. Please take the time to give your thoughts.

Dieter Fishbein, Ecosystem Development Lead, Web3 Foundation

Dan: Hey everyone, thanks for joining us for the Polkadot Launch AMA. We have Dieter Fishbein (Head of Ecosystem Development, our business development team), Logan Saether (Technical Education), and Will Pankiewicz (Master of Validators) joining us today.
We had some great questions submitted in advance, and we’ll start by answering those and learning a bit about each of our guests. After we go through the pre-submitted questions, then we’ll open up the chat to live Q&A and the hosts will answer as many questions as they can.
We’ll start off with Dieter and ask him a set of some business-related questions.

Dieter could you introduce yourself, your background, and your role within the Polkadot ecosystem?

Dieter: I got my start in the space as a cryptography researcher at the University of Waterloo. This is where I first learned about Bitcoin and started following the space. I spent the next four years or so on the investment team for a large asset manager where I primarily focused on emerging markets. In 2017 I decided to take the plunge and join the space full-time. I worked at a small blockchain-focused VC fund and then joined the Polkadot team just over a year ago. My role at Polkadot is mainly focused on ensuring there is a vibrant community of projects building on our technology.

Q: Adoption of Polkadot of the important factors that all projects need to focus on to become more attractive to the industry. So, what is Polkadot's plan to gain more Adoption? [sic]

A (Dieter): Polkadot is fundamentally a developer-focused product so much of our adoption strategy is focused around making Polkadot an attractive product for developers. This has many elements. Right now the path for most developers to build on Polkadot is by creating a blockchain using the Substrate framework which they will later connect to Polkadot when parachains are enabled. This means that much of our adoption strategy comes down to making Substrate an attractive tool and framework. However, it’s not just enough to make building on Substrate attractive, we must also provide an incentive to these developers to actually connect their Substrate-based chain to Polkadot. Part of this incentive is the security that the Polkadot relay chain provides but another key incentive is becoming interoperable with a rich ecosystem of other projects that connect to Polkadot. This means that a key part of our adoption strategy is outreach focused. We go out there and try to convince the best projects in the space that building on our technology will provide them with significant value-add. This is not a purely technical argument. We provide significant support to projects building in our ecosystem through grants, technical support, incubatoaccelerator programs and other structured support programs such as the Substrate Builders Program (https://www.substrate.io/builders-program). I do think we really stand out in the significant, continued support that we provide to builders in our ecosystem. You can also take a look at the over 100 Grants that we’ve given from the Web3 Foundation: https://medium.com/web3foundation/web3-foundation-grants-program-reaches-100-projects-milestone-8fd2a775fd6b

Q: On moving forward through your roadmap, what are your most important next priorities? Does the Polkadot team have enough fundamentals (Funds, Community, etc.) to achieve those milestones?

A (Dieter): I would say the top priority by far is to ensure a smooth roll-out of key Polkadot features such as parachains, XCMP and other key parts of the protocol. Our recent Proof of Authority network launch was only just the beginning, it’s crucial that we carefully and successfully deploy features that allow builders to build meaningful technology. Second to that, we want to promote adoption by making more teams aware of Polkadot and how they can leverage it to build their product. Part of this comes down to the outreach that I discussed before but a major part of it is much more community-driven and many members of the team focus on this.
We are also blessed to have an awesome community to make this process easier 🙂

Q: Where can a list of Polkadot's application-specific chains can be found?

A (Dieter): The best list right now is http://www.polkaproject.com/. This is a community-led effort and the team behind it has done a terrific job. We’re also working on providing our own resource for this and we’ll share that with the community when it’s ready.

Q: Could you explain the differences and similarities between Kusama and Polkadot?

A (Dieter): Kusama is fundamentally a less robust, faster-moving version of Polkadot with less economic backing by validators. It is less robust since we will be deploying new technology to Kusama before Polkadot so it may break more frequently. It has less economic backing than Polkadot, so a network takeover is easier on Kusama than on Polkadot, lending itself more to use cases without the need for bank-like security.
In exchange for lower security and robustness, we expect the cost of a parachain lease to be lower on Kusama than Polkadot. Polkadot will always be 100% focused on security and robustness and I expect that applications that deal with high-value transactions such as those in the DeFi space will always want a Polkadot deployment, I think there will be a market for applications that are willing to trade cheap, high throughput for lower security and robustness such as those in the gaming, content distribution or social networking sectors. Check out - https://polkadot.network/kusama-polkadot-comparing-the-cousins/ for more detailed info!

Q: and for what reasons would a developer choose one over the other?

A (Dieter): Firstly, I see some earlier stage teams who are still iterating on their technology choosing to deploy to Kusama exclusively because of its lower-stakes, faster moving environment where it will be easier for them to iterate on their technology and build their user base. These will likely encompass the above sectors I identified earlier. To these teams, Polkadot becomes an eventual upgrade path for them if, and when, they are able to perfect their product, build a larger community of users and start to need the increased stability and security that Polkadot will provide.
Secondly, I suspect many teams who have their main deployment on Polkadot will also have an additional deployment on Kusama to allow them to test new features, either their tech or changes to the network, before these are deployed to Polkadot mainnet.

Logan Saether, Technical Education, Web3 Foundation

Q: Sweet, let's move over to Logan. Logan - could you introduce yourself, your background, and your role within the Polkadot ecosystem?

A (Logan): My initial involvement in the industry was as a smart contract engineer. During this time I worked on a few projects, including a reboot of the Ethereum Alarm Clock project originally by Piper Merriam. However, I had some frustrations at the time with the limitations of the EVM environment and began to look at other tools which could help me build the projects that I envisioned. This led to me looking at Substrate and completing a bounty for Web3 Foundation, after which I applied and joined the Technical Education team. My responsibilities at the Technical Education team include maintaining the Polkadot Wiki as a source of truth on the Polkadot ecosystem, creating example applications, writing technical documentation, giving talks and workshops, as well as helping initiatives such as the Thousand Validator Programme.

Q: The first technical question submitted for you was: "When will an official Polkadot mobile wallet appear?"

A (Logan): There is already an “official” wallet from Parity Technologies called the Parity Signer. Parity Signer allows you to keep your private keys on an air-gapped mobile device and to interactively sign messages using web interfaces such as Polkadot JS Apps. If you’re looking for something that is more of an interface to the blockchain as well as a wallet, you might be interested in PolkaWallet which is a community team that is building a full mobile interface for Polkadot.
For more information on Parity Signer check out the website: https://www.parity.io/signe

Q: Great thanks...our next question is: If someone already developed an application to run on Ethereum, but wants the interoperability that Polkadot will offer, are there any advantages to rebuilding with Substrate to run as a parachain on the Polkadot network instead of just keeping it on Ethereum and using the Ethereum bridge for use with Polkadot?

A (Logan): Yes, the advantage you would get from building on Substrate is more control over how your application will interact with the greater Polkadot ecosystem, as well as a larger design canvas for future iterations of your application.
Using an Ethereum bridge will probably have more cross chain latency than using a Polkadot parachain directly. The reason for this is due to the nature of Ethereum’s separate consensus protocol from Polkadot. For parachains, messages can be sent to be included in the next block with guarantees that they will be delivered. On bridged chains, your application will need to go through more routes in order to execute on the desired destination. It must first route from your application on Ethereum to the Ethereum bridge parachain, and afterward dispatch the XCMP message from the Polkadot side of the parachain. In other words, an application on Ethereum would first need to cross the bridge then send a message, while an application as a parachain would only need to send the message without needing to route across an external bridge.

Q: DOT transfers won't go live until Web3 removes the Sudo module and token holders approve the proposal to unlock them. But when will staking rewards start to be distributed? Will it have to after token transfers unlock? Or will accounts be able to accumulate rewards (still locked) once the network transitions to NPoS?

A (Logan): Staking rewards will be distributed starting with the transition to NPoS. Transfers will still be locked during the beginning of this phase, but reward payments are technically different from the normal transfer mechanism. You can read more about the launch process and steps at http://polkadot.network/launch-roadmap

Q: Next question is: I'm interested in how Cumulus/parachain development is going. ETA for when we will see the first parachain registered working on Kusama or some other public testnet like Westend maybe?

A (Logan): Parachains and Cumulus is a current high priority development objective of the Parity team. There have already been PoC parachains running with Cumulus on local testnets for months. The current work now is making the availability and validity subprotocols production ready in the Polkadot client. The best way to stay up to date would be to follow the project boards on GitHub that have delineated all of the tasks that should be done. Ideally, we can start seeing parachains on Westend soon with the first real parachains being deployed on Kusama thereafter.
The projects board can be viewed here: https://github.com/paritytech/polkadot/projects
Dan: Also...check out Basti's tweet from yesterday on the Cumulus topic: https://twitter.com/bkchstatus/1270479898696695808?s=20

Q: In what ways does Polkadot support smart contracts?

A (Logan): The philosophy behind the Polkadot Relay Chain is to be as minimal as possible, but allow arbitrary logic at the edges in the parachains. For this reason, Polkadot does not support smart contracts natively on the Relay Chain. However, it will support smart contracts on parachains. There are already a couple major initiatives out there. One initiative is to allow EVM contracts to be deployed on parachains, this includes the Substrate EVM module, Parity’s Frontier, and projects such as Moonbeam. Another initiative is to create a completely new smart contract stack that is native to Substrate. This includes the Substrate Contracts pallet, and the ink! DSL for writing smart contracts.

Will Pankiewicz, Master of Validators, Parity Technologies


Q: (Dan) Thanks for all the answers. Now we’ll start going through some staking questions with Will related to validating and nominating on Polkadot. Will - could you introduce yourself, your background, and your role within the Polkadot ecosystem?

A (Will): Sure thing. Like many others, Bitcoin drew me in back in 2013, but it wasn't until Ethereum came that I took the deep dive into working in the space full time. It was the financial infrastructure aspects of cryptocurrencies I was initially interested in, and first worked on dexes, algorithmic trading, and crypto funds. I really liked the idea of "Generalized Mining" that CoinFund came up with, and started to explore the whacky ways the crypto funds and others can both support ecosystems and be self-sustaining at the same time. This drew me to a lot of interesting experiments in what later became DeFi, as well as running validators on Proof of Stake networks. My role in the Polkadot ecosystem as “Master of Validators” is ensuring the needs of our validator community get met.

Q: Cool thanks. Our first community question was "Is it still more profitable to nominate the validators with lesser stake?"

A (Will): It depends on their commission, but generally yes it is more profitable to nominate validators with lesser stake. When validators have lesser stake, when you nominate them this makes your nomination stake a higher percentage of total stake. This means when rewards get distributed, it will be split more favorably toward you, as rewards are split by total stake percentage. Our entire rewards scheme is that every era (6 hours in Kusama, 24 hours in Polkadot), a certain amount of rewards get distributed, where that amount of rewards is dependent on the total amount of tokens staked for the entire network (50% of all tokens staked is currently optimal). These rewards from the end of an era get distributed roughly equally to all validators active in the validator set. The reward given to each validator is then split between the validators and all their nominators, determined by the total stake that each entity contributes. So if you contribute to a higher percentage of the total stake, you will earn more rewards.

Q: What does priority ranking under nominator addresses mean? For example, what does it mean that nominator A has priority 1 and nominator B has priority 6?

A (Will): Priority ranking is just the index of the nomination that gets stored on chain. It has no effect on how stake gets distributed in Phragmen or how rewards get calculated. This is only the order that the nominator chose their validators. The way that stake from a nominator gets distributed from a nominator to validators is via Phragmen, which is an algorithm that will optimally put stake behind validators so that distribution is roughly equal to those that will get in the validator set. It will try to maximize the total amount at stake in the network and maximize the stake behind minimally staked validators.

Q: On Polkadot.js, what does it mean when there are nodes waiting on Polkadot?

**A (Will):**In Polkadot there is a fixed validator set size that is determined by governance. The way validators get in the active set is by having the highest amount of total stake relative to other validators. So if the validator set size is 100, the top 100 validators by total stake will be in the validator set. Those not active in the validator set will be considered “waiting”.

Q: Another question...Is it necessary to become a waiting validator node right now?

A (Will): It's not necessary, but highly encouraged if you actively want to validate on Polkadot. The longer you are in the waiting tab, the longer you get exposure to nominators that may nominate you.

Q: Will current validators for Kusama also validate for Polkadot? How strongly should I consider their history (with Kusama) when looking to nominate a good validator for DOTs?

A (Will): A lot of Kusama validators will also be validators for Polkadot, as KSM was initially distributed to DOT holders. The early Kusama Validators will also likely be the first Polkadot validators. Being a Kusama validator should be a strong indicator for who to nominate on Polkadot, as the chaos that has ensued with Kusama has allowed validators to battle test their infrastructure. Kusama validators by now are very familiar with tooling, block explorers, terminology, common errors, log formats, upgrades, backups, and other aspects of node operation. This gives them an edge against Polkadot validators that may be new to the ecosystem. You should strongly consider well known Kusama validators when making your choices as a nominator on Polkadot.

Q: Can you go into more details about the process for becoming a DOT validator? Is it similar as the KSM 1000 validators program?

A (Will): The Process for becoming a DOT validators is first to have DOTs. You cannot be a validator without DOTs, as DOTs are used to pay transaction fees, and the minimum amount of DOTs you need is enough to create a validate transaction. After obtaining enough DOTs, you will need to set up your validator infrastructure. Ideally you should have a validator node with specs that match what we call standard hardware, as well as one or more sentry nodes to help isolate the validator node from attacks. After the infrastructure is up and running, you should have your Polkadot accounts set up right with a stash bonded to a controller account, and then submit a validate transaction, which will tell the network your nodes are ready to be a part of the network. You should then try and build a community around your validator to let others know you are trustworthy so that they will nominate you. The 1000 validators programme for Kusama is a programme that gives a certain amount of nominations from the Web3 Foundation and Parity to help bootstrap a community and reputation for validators. There may eventually be a similar type of programme for Polkadot as well.
Dan: Thanks a lot for all the answers, Will. That’s the end of the pre-submitted questions and now we’ll open the chat up to live Q&A, and our three team members will get through as many of your questions as possible.
We will take questions related to business development, technology, validating, and staking. For those wondering about DOT:
DOT tokens do not exist yet. Allocations of Polkadot's native DOT token are technically and legally non-transferable. Hence any publicized sale of DOTs is unsanctioned by Web3 Foundation and possibly fraudulent. Any official public sale of DOTs will be announced on the Web3 Foundation website. Polkadot’s launch process started in May and full network decentralization later this year, holders of DOT allocations will determine issuance and transferability. For those who participated in previous DOT sales, you can learn how to claim your DOTs here (https://wiki.polkadot.network/docs/en/claims).


Telegram Community Follow-up Questions Addressed Below


Q: Polkadot looks good but it confuses me that there are so many other Blockchain projects. What should I pay attention in Polkadot to give it the importance it deserves? What are your planning to achieve with your project?

A (Will): Personally, what I think differentiates it is the governance process. Coordinating forkless upgrades and social coordination helps stand it apart.
A (Dieter): The wiki is awesome - https://wiki.polkadot.network/

Q: Over 10,000 ETH paid as a transaction fee , what if this happens on Polkadot? Is it possible we can go through governance to return it to the owner?

A: Anything is possible with governance including transaction reversals, if a network quorum is reached on a topic.
A (Logan): Polkadot transaction fees work differently than the fees on Ethereum so it's a bit more difficult to shoot yourself in the foot as the whale who sent this unfortunate transaction. See here for details on fees: https://w3f-research.readthedocs.io/en/latest/polkadot/Token%20Economics.html?highlight=transaction%20fees#relay-chain-transaction-fees-and-per-block-transaction-limits
However, there is a tip that the user can input themselves which they could accidentally set to a large amount. In this cases, yes, they could proposition governance to reduce the amount that was paid in the tip.

Q: What is the minimum ideal amount of DOT and KSM to have if you want to become a validator and how much technical knowledge do you need aside from following the docs?

A (Will): It depends on what the other validators in the ecosystem are staking as well as the validator set size. You just need to be in the top staking amount of the validator set size. So if its 100 validators, you need to be in the top 100 validators by stake.

Q: Will Web3 nominate validators? If yes, which criteria to be elected?

A (Will): Web 3 Foundation is running programs like the 1000 validators programme for Kusama. There's a possibility this will continue on for Polkadot as well after transfers are enabled. https://thousand-validators.kusama.network/#/
You will need to be an active validator to earn rewards. Only those active in the validator set earn rewards. I would recommend checking out parts of the wiki: https://wiki.polkadot.network/docs/en/maintain-guides-validator-payout

Q: Is it possible to implement hastables or dag with substrate?

A (Logan): Yes.

Q: Polkadot project looks very futuristic! But, could you tell us the main role of DOT Tokens in the Polkadot Ecosystem?

A (Dan): That's a good question. The short answer is Staking, Governance, Bonding. More here: http://polkadot.network/dot-token

Q: How did you manage to prove that the consensus protocol is safe and unbreakable mathematically?

A (Dieter): We have a research teams of over a dozen scientists with PhDs and post-docs in cryptography and distributed computing who do thorough theoretical analyses on all the protocols used in Polkadot

Q: What are the prospects for NFT?

A: Already being built 🙂

Q: What will be Polkadot next roadmap for 2020 ?

A (Dieter): Building. But seriously - we will continue to add many more features and upgrades to Polkadot as well as continue to strongly focus on adoption from other builders in the ecosystem 🙂
A (Will): https://polkadot.network/launch-roadmap/
This is the launch roadmap. Ideally adding parachains and xcmp towards the end of the year

Q: How Do you stay active in terms of marketing developments during this PANDEMIC? Because I'm sure you're very excited to promote more after this settles down.

A (Dan): The main impact of covid was the impact on in-person events. We have been very active on Crowdcast for webinars since 2019, so it was quite the smooth transition to all-online events. You can see our 40+ past event recordings and follow us on Crowdcast here: https://www.crowdcast.io/polkadot. If you're interested in following our emails for updates (including online events), subscribe here: https://info.polkadot.network/subscribe

Q: Hi, who do you think is your biggest competitor in the space?

A (Dan): Polkadot is a metaprotocol that hasn't been seen in the industry up until this point. We hope to elevate the industry by providing interoperability between all major public networks as well as private blockchains.

Q: Is Polkadot a friend or competitor of Ethereum?

A: Polkadot aims to elevate the whole blockchain space with serious advancements in interoperability, governance and beyond :)

Q: When will there be hardware wallet support?

A (Will): Parity Signer works well for now. Other hardware wallets will be added pretty soon

Q: What are the attractive feature of DOT project that can attract any new users ?

A: https://polkadot.network/what-is-polkadot-a-brief-introduction/
A (Will): Buidling parachains with cross chain messaging + bridges to other chains I think will be a very appealing feature for developers

Q: According to you how much time will it take for Polkadot to get into mainstream adoption and execute all the plans set for this project?

A: We are solving many problems that have held back the blockchain industry up until now. Here is a summary in basic terms:
https://preview.redd.it/ls7i0bpm8p951.png?width=752&format=png&auto=webp&s=a8eb7bf26eac964f6b9056aa91924685ff359536

Q: When will bitpie or imtoken support DOT?

A: We are working on integrations on all the biggest and best wallet providers. ;)

Q: What event/call can we track to catch a switch to nPOS? Is it only force_new_era call? Thanks.

A (Will): If you're on riot, useful channels to follow for updates like this are #polkabot:matrix.org and #polkadot-announcements:matrix.parity.io
A (Logan): Yes this is the trigger for initiating the switch to NPoS. You can also poll the ForceEra storage for when it changes to ForceNew.

Q: What strategy will the Polkadot Team use to make new users trust its platform and be part of it?

A (Will): Pushing bleeding edge cryptography from web 3 foundation research
A (Dan): https://t.me/PolkadotOfficial/43378

Q: What technology stands behind and What are its advantages?

A (Dieter): Check out https://polkadot.network/technology/ for more info on our tech stack!

Q: What problems do you see occurring in the blockchain industry nowadays and how does your project aims to solve these problems?

A (Will): Governance I see as a huge problem. For example upgrading Bitcoin and making decisions for changing things is a very challenging process. We have robust systems of on-chain governance to help solve these coordination problems

Q: How involved are the Polkadot partners? Are they helping with the development?

A (Dieter): There are a variety of groups building in the Polkadot ecosystem. Check out http://www.polkaproject.com/ for a great list.

Q: Can you explain the role of the treasury in Polkadot?

A (Will): The treasury is for projects or people that want to build things, but don't want to go through the formal legal process of raising funds from VCs or grants or what have you. You can get paid by the community to build projects for the community.
A: There’s a whole section on the wiki about the treasury and how it functions here https://wiki.polkadot.network/docs/en/mirror-learn-treasury#docsNav

Q: Any plan to introduce Polkadot on Asia, or rising market on Asia?

**A (Will):**We're globally focused

Q: What kind of impact do you expect from the Council? Although it would be elected by token holders, what kind of people you wish to see there?

A (Will): Community focused individuals like u/jam10o that want to see cool things get built and cool communities form

If you have further questions, please ask in the official Polkadot Telegram channel.

Technical details of the Earthcoin network 2019

Technical details of the Earthcoin network 2019
Blockchain parameters
crypt hashing algorithm
Proof of Work (POW) mining
60 seconds block target
Difficulty retarget after each block (+167%, -91%)
Total coins will be 13.5 billion coins (infinite by a theory, because the minimal block reward is 1 EAC, but in the practice 13.5*109 will not be exceeded within the next 2000 years)
50 confirmations per minted block
5 confirmations per transaction
Supports transaction messages
Initial block reward on average 10,000 EAC, varies seasonly ( currently 625 EAC) Block payout is halved every year, minimum payout of 1 EAC per block Superblocks every 14 and 31 day The default ports are 35677 (P2P-network) and 15678 (RPC-calls, optional)
Transaction speed
The mechanism behind Earthcoin which is based on peer-to-peer, allows transactions to happen very quickly. This means that once you pay or get payed with Earthcoin, the time taken to see the money transferred is equal or sometimes faster than the avarege debit card. Earthcoin promotes transaction times of approximatly 30 seconds where it is actually closer to 10-15 seconds which is nowadays regarded as being instant. The true strength behind this speed is the abillity to use it in any store in the near future with the same feel of speed as the currency you hold today.
Security
The Earthcoin network had been attacked by a 51% attack and controlled by a group of hackers for several months in the middle of 2017. Thanks to the unwavering efforts of the community, the attack was thrown back and EarthCoin was returned to all users. The source code was then fixed, secured against similar attacks in the future and a unique protection against time travel attack was implemented. The EarthCoin code is now much more secure than most of other cryptocurrencies. In the first half of 2019, a major upgrade of the Earthcoin network was done and security features according to the current blockchain protocol of Bitcoin and Litecoin networks were implemented.

Doing the Math on the S4E10 eCoin Transaction...

In this week's Mr Robot episode, Darlene sits on a park bench with Dom, and distributes the money she stole from the Deus Group to everybody, evenly. I timed the transaction as it happened in the show. It was 24 seconds, between her hitting return and seeing the following message on her screen: "*Transfers Complete. All Wallets Updated*" This processing time includes a message that says, "cleaning coins through crypto tumbler". It took 1 minute and 16 seconds for the transaction to tumble, process, and for the recipients to begin to get notices that they received money in their accounts.
If you have worked with bitcoin, you know that cryptocurrency does not work like this. Transferring money is a slow and sometimes expensive process, as transaction fees eat into every transaction. I know that eCoin isn't necissarily bitcoin, because it's controlled by eCorp, but it's fun to think about what happens if eCoin works like bitcoin does today...
How much money was transferred?
According to Forbes, the most wealthy people in the world are worth a combined $8.7 trillion, or $2.7 trillion. It depends on which Forbes list you are looking at. On the actual Forbes web site, they say the richest people in the world are worth $8.7 trillion, but they do not state how many of the richest people in the world are worth that much. If you look at sites like Victor Media, they publish a table of the 100 most wealthy people, and say they got the list from Forbes. They probably did purchase the list from Forbes. If I put the Victor Media list into excel, and add all the values in the net worth column, that number comes out to $2.7 trillion. So Forbes might be talking about a list that is more than the top 100 people, and sell the top 100 people list to sites like Victor Media? I don't know.
Either way, we are talking about somewhere between $2.7 and $8.7 trillion.
How many people did the money go to?
That's complicated. There was no global montage showing people celebrating all over the world (which I found a little surprising, even though I still love how this episode was shot). The only indication of a truly global transfer, to every individual in the world, is a TV screen in the airport saying that, "Global eCoin Payout... Deus group collapses as wealth spreads around the world." So Darlene could have sent the money to every individual with an eCoin wallet in the world, or she could be sending them to every American, or to everybody in the developed world. I doubt the average rice farmer in Indonesia is really using eCoin, but it's possible. If she only sent it to every American, our wealth tends to spread around the globe pretty fast, so that's possible, too.
Lets work with World Bank population numbers for all three of these possibilities...
World Population: 7.6 billion people
Global North (AKA the developed world): 1.24 billion people
United States: 327 million people
So we have 6 possibilities for how much money was sent to each person...
People Total Money Money Per Capita Satoshis
7.6 billion $2.7 trillion $355.53 4,739,471
1.21 billion $2.7 trillion $2230.82 29,741,808
327 million $2.7 trillion $8252.65 110,079,512
7.6 billion $8.7 trillion $1145.60 15,279,332
1.21 billion $8.7 trillion $7188.22 95,883,716
327 million $8.7 trillion $26591.89 355,275,242
How much would this transaction cost with bitcoin?
Aside from the fact that eCoin probably functions differently than bitcoin, this is a very complex question. I'm definitely not as sure about these numbers as the other numbers I have, but I'll do my best to come up with useful, realistic numbers. If you are more familiar with the block chain than me, please correct me.
The coins were taken from 100 different Deus Group accounts. Lets say each transaction launders through a bitcoin tumbler 1,000 times. I'm going to ignore transaction fees for the tumbling process, because I don't fully understand the details of tumbling, but 1,000 times seems reasonable to me.
That means that there are 100 x 1,000 = 10,000 inputs in any transaction that spends all the money from the Deus group.
For outputs... for simplicity's sake, I will make the conservative assumption that everybody has one eCoin wallet. That means somewhere between 327 million and 7.6 billion outputs. Accounting for everybody having multiple wallets would make the transaction even bigger, but this is a good starting point to get a feel for what this transaction would look like, in the real world.
How long will this transaction take to process?
There is a bidding process and a bit of politics involved in processing a cryptocurrency transaction. For simplicity, I'll assume we bid enough that this transaction gets priority treatment from the bitcoin miners.
According to blockchain.com, transactions happen on the block chain at a rate of roughly 3.5 transactions per second. At that rate, the tumbling would take roughly 48 minutes, rather than the few seconds it took for Darlene to tumble this money.
According to buybitcoinworldwide.com's fee calculator, here are the transaction sizes, the transaction fees involved (in US Dollars), and the time it would take at 3.5 transactions per second...
Inputs Outputs Size Cost Time
10,000 7.6 billion 240.4737 Gb $38,884,280.55 68.85 years
10,000 1.21 billion 38.32587 Gb $6,192,571.09 10.96 years
10,000 327 million 10.35582 Gb $1,673,260.46 2.96 years
So this transaction would take years to go through, and it pays Evil Corp somewhere between $1.6 and $38 million. In the real world, most of that money would go to Chinese bitcoin miners.
What would the impact be?
A one time windfall of $327 per capita would probably not trigger hyperinflation in America. The largest payout we calculated was $26.5k, and I doubt that would cause hyperinflation, either. Regular inflation? Yes. Hyperinflation? Probably not.
It might lead to hyperinflation in other countries, though, because of differences in purchasing power.
Purchasing power parity is a number that describes the differences in the cost of goods and services around the world. $5 in America will buy you a big mac, but if you go to, say, Indonesia, you can buy a lot more with that $5, because Indonesia is full of people who make something like 25 cents a week.
OECD.org publishes PPP (purchasing power parity) numbers for countries all around the world. If you want to know how far your dollar will stretch, on average, in a foreign country, consult this list. If you have $100 in America, you can expect it to be worth $100 worth of American goods and services, so on the OECD table, it has a PPP of 1.0. If you take that $100 to, say, the UK, where the PPP is 0.7, you can expect that $100 to be worth $70 worth of goods and services. If you take that $100 to Australia, where the PPP is 1.48, you can expect that $100 to buy roughly $148 worth of goods and services.
If Elliot and Darlene were genius economists, I might expect them to account for PPP in their payout. They would have to be geniuses, to predict what PPP is doing after events like the 5/9 hack, because their best data would be out of date, so they would have to use all kinds of fancy regressions and tricks to figure out how that would work in such a volatile world economy. They definitely aren't economists, though, so I'll assume they sent the same nominal amount to everybody.
So what's the range on how much purchasing power this transaction gives people around the world? In 2018, the highest PPP number on the OECD list is Indonesia, with a PPP of 4,245.613140. The lowest PPP on the list is Lithuania, with a PPP of 0.457582. Lets see how this shakes out in each of these countries...
$ Per Capita Lithuania (0.46) Indonesia (4,245.61)
$355.53 $162.68 $1,509,442.84
$2,230.82 $1,020.78 $9,471,198.70
$8,252.65 $3,776.26 $35,037,559.28
$1,145.60 $524.20 $4,863,774.41
$7,188.22 $3,289.20 $30,518,401.29
$26,591.89 $12,167.97 $112,898,877.60
What would this cause? People might predict a lot of different things. The Yang gang people probably strong opinions on this. I have a bachelor's degree in economics, so I believe I can predict that most mainstream economists would predict the following...
In Lithuania, when they get a few hundred to a few thousand dollars, they probably raise a pint to F Society, then put the rest towards a house or car payment, or buy themselves something nice. Minor inflation would happen, probably starting at the pubs, and that would worry financial types, but it would not cause any kind of major economic catastrophe.
In Indonesia, where everybody becomes an asset millionaire overnight, they will probably have hyperinflation, mass social upheaval, and violence.
In conclusion...
TL;DR: What Darlene did last night with eCoin isn't actually possible with bitcoin, and the impact in America might not be as great as you think, but the impact would be much bigger in poorer parts of the world.

my moon hypothesis

I think monero's gonna goto the moon. Here's the reason why.

First, the general market seems to be in an upswing... this will naturally increase the price of monero (along with other alts). This rise in price will once again cause an increase in interest from outside of the crypto space.
For a lot of people new to the space, the idea of mining is attractive and fascinating. You can print money with your computer. What? Full stop. I remember reading a while ago that this component of nakamoto consensus has an allure because it is akin to alchemy, and apparently human culture has always had a fascination with alchemy.
So, these newcomers will think (as many do) "I should get into mining". They may do some research and discover that bitcoin mining is dead. Eventually they'll come across the fact that Monero is still CPU mineable. And at these bubble run prices, it could probably even turn a profit! So they'll set their PC to mine. Or maybe buy another PC.
And they'll mine.
And they'll read more about monero. They'll become fascinated with why (and how) monero is a privacy coin. They'll become fascinated with why (and how) monero has chosen to have a CPU-bound PoW. They'll probably also come across the tail emission, and why Monero has one, which will then get them reading about base layer scaling.
And they'll mine some more.
And they'll read some more about monero. They'll come across this notion of fungibility. They'll perhaps start to understand how blockchains work, and how consensus protocols work, and how base-layer protocol is the most important protocol for a cryptocurrency.
Probably after mining for a month, watching the price of monero increase and their pooled mining payout threshold *never* coming close to hitting, and all the while reading this or that about monero, they'll say "well, the only way I'm gonna get a good lot of this Monero is to buy some". And hopefully they'll be able to navigate the morass of AML/KYC(M - o - U - s - E) and get their hands on some.
And thats demand. On the buy side.
And where's the pressure from the sell side? Monero's emission just went under 2 xmr a block. And this new emission isn't going to mining farms with bottom lines to cover, so they always need to sell to keep the lights on.
No, its going to people like this, 500 khs bunch of workers with 1.7 to 7 kh/s per worker. Probably a sysadmin somewhere that has idle CPUs that they've decided to mine with.
or this glorious bastard, with 2.2 Mh/s. Their overall activity has a wave pattern, and the worker distribution seems like contemporary intel / amd PCs.
And then you get the ones like this, 11 Mh/s peak with a glorious wave pattern. This one is so cyclical you can't see the online workers because they seem to turn off every day at the same time. Or they have an agreement with nanopool to hide their worker details. But the waves are still visible.
And its also going to solo miners, like this guy. Roughly 13% of the found blocks aren't accounted for via the major pool aggregation website. I don't wanna make up numbers here, but what if that 13% is all just lucky solo miners?
There's ~1440 monero printed every day at this point. How much of that is going straight to market? Based on the fundamental differences in the monero mining ecosystem, I'd bet that more of the newly minted coin is going straight into cold, deep storage.
Of course, the markets are all just manipulated nonsense, so it really just depends on when some whale decides to market buy a bajillion xmr for the lulz.

Actual cost of a 51% attach, $10.2 million

So I was discussing this last week and honestly it all felt too simple, so I'm trying to get some stronger counterpoints to this argument. Goes something like this.
You have some pool miner that wants to do a 51% attack. Lets assume the attack has three phases, the first phase is to try to accumulate 51% of the hashing power, next is the accumulation of more hashing power by ejecting other pools from through reorg. Finally when they aquired enough mining power they could blacklist exchange hotwallets or all manner of nefariousness. Lets further assume that everyone will act purely in their own self interest. For simplicity lets call the attacker "Spectre Pool".

Accumulation Phase

Assuming Spectre Pool can hit something like 41% of the hashing power, the first goal is to accumulate more resources to hit 51%. Since pool mining is a commodity market, all Spectre has to do in this imaginary world is offer more than the market rate. Since they are already at 41% hashrate, they need to entice another 10% of the market to come to their pool. The obvious way to do this would be to offer a "new customer bonus" or something like that. Some promotion where they pay 1% above market price for the hashing power of pool members. So, given a network hashrate of 116.73 EH and a market rate of 0.101 USD/TH per day, the cost they would have to bear to offer a 1% promotion to entice 10% of the network would be:
116.73_EH / 0.101_USD/TH * 10% * 1% = 1,155,742 USD per day for each 1% "bonus"
So, assuming they were willing to spend that much on "marketing", and that all miners worked in their own self interest, eventually they could lure enough miners over to achive 51%. Once they hit this threshold they could scale back on the "marketing" and thus reduce their daily burn.

Acceleration phase

Once at 51%, the next attack of Spectre will be to put their smallest competitor out of buisness. Lets call that the "Bond Pool", and pretend that Bond has 1.5% of the network hashing power. To put Bond out of buisness, with 51%, Spectere will need to reorg whenever Bond wins a block. By reorging to a chain without Bond, this will put Spectre one block behind and they will need to catch up. Once the reorg begins, Spectre will need to produce the longest chain on its own while starting one block behind. So we need to determine how long (statisticly) it will take Specter to produce n+1 blocks and compare that to how long (statisticly) it will take Bond to win one block.
Although this can be hammered out in an iterive calculation, a better approach will be an algebraic solution. Lets walk through the equations:
You can put the following into a GeoGebra CAS calculator to substitute and simplify the equations
solve(n*m = s*(n+1), n) M = 1/2-d S = 1/2+d m = t/M s = t/S solve(n*m = s*(n+1), d) n = s/(m-s) b = m*M/p solve(b = s*(n+1),p)
This will produce the following equations for the values we are interested in.
m(t,d): t/(1/2-d) # from `m` define s(t,d): t/(1/2-d) # from `s` define n(s,m): s/(m-s) # from `n` solve d(n): 1/(4*n+2) # from `d` solve p(d): 2*d # from `p` solve b(t,p): t/p # from `b` define
Plugging the equations into excel produces the following (assuming t=10)
n d p m s b
25 0.98% 1.96% 20.40 19.62 510
20 1.22% 2.44% 20.50 19.52 410
15 1.61% 3.23% 20.67 19.38 310
10 2.38% 4.76% 21 19.09 210
5 4.55% 9.09% 22 18.33 110
4 5.56% 11.11% 22.50 18 90
3 7.14% 14.29% 23.33 17.50 70
2 10% 20% 25 16.67 50
1 16.67% 33.33% 30 15 30
So once d=0.98%, Specture will have 50.98% of the hashing power, allowing him to eject 1.96% of all blocks mined at will. Of course this is all statistical, so Spectre will want some margin for randomness. So it would make sense to attach 1.5% of the blocks when Spectre reaches 51%
So once Spectre reaches 51% he has enough hashing power to prevent any of Bonds blocks (1.5%) from being included. Spectre can win a reorg (statistically) every 8.5 hrs and Bond can only produce a block (statisticly) every 11.1 hours. So once this attack starts, Spectre simply flashes his promotion to lure the miners in the Bond pool (who are receiving no reward) over to the Spectre pool. If he only gets one third of them, then he can increase his influence to 52%
Doing the same math again, with 52% Spectre can ice out any pool who has up to 4% of the hashing. Then running the promotion, Spectre will try to get 40% of the "homeless miners". Now Spectre's power grows to 55% giving him the power to ice out 10% of his competitors. This can cascade on and on until Spectre is the only public pool left.
Now, at 51% the attack and reorgs take many hours, but as more and more pools get targeted, more and more miners will jump ship and end up at Spectre so long as they can hold the promotion. Bond's only choice would be to either close up, or leverage everything and mine at a loss for weeks hoping that Spectre eventually drops below the threshold for his attack.
Of course Spectre has even more tremendous expenses. To offer the 1% promo to 10% of the network would cost Spectre $1.16 million / day, or 3.52 million per month for each percent of miners it lures over. So going from 41% to 61% would cost Spectre $70.3 million / month, but at that point he can attack 20% of the network giving him a reach of about 80% which is pretty much the entire pooled mining capacity today. Seems like $70 million is a small price to pay to buy the entire bitcoin network.
Other expenses Spectre would accrue would be related to the attacks and reorgs. The early attacks will take hours and throughout Spectre needs to continue payouts to the pool even though he is generating no BTC durring the attack. So long as his chain is orphaned, his blocks have no value. Only after the attack and reorg when his chain becomes longest will he be able to claim the block reward for all the blocks he minded. This (in my opinion) will the the hardest challenge. The first attack and 25 block reorg will require Spectre to put his entire 51% hashing power on an orphaned chain for 8 hours requireing $208.6 million in payouts. Once he wins the attack and the chain reorgs he can cover his expeses with the block reward, but borrowing $208 million for 8 hours is still a very difficult thing to pull off. The interest alone on the attack is over $40,000 (20% interest compounded continually). Below is a table of the calculations
Specte Bond Promo Cost Hrs Blks Levrg / Block Reorg Leverage Rate Int Cost
51.00% 1.50% $1,155,743 8.497 25 $8,025,990 $208,675,743 20% $40,485
51.50% 2.50% $1,232,745 5.825 17 $8,025,990 $144,467,822 20% $19,215
52.50% 4.50% $1,336,143 3.492 10 $8,025,990 $88,285,891 20% $7,039
54.50% 7.50% $1,562,998 2.141 6 $8,025,990 $56,181,931 20% $2,746
58.50% 14.50% $2,023,385 1.140 3 $8,025,990 $32,103,960 20% $835
66.70% 33.30% $2,970,442 0.500 1 $8,025,990 $16,051,980 20% $183
Of course, once Spectre gets 2/3 of the hashing power he controls the entire chain since he can include or exclude any block he wants. So this "Total Self Interest" simulation of a 6 day attack puts Spectre's expenses at $10.3 million in promotions and $71,000 in interest, or about $10.4 million total.
1 - All "hashes" are hashes per second
2 - TH = 1012 or 10004 hashes per second
3 - EH = 1018 or 10006 hashes per second
4 - Assume a market rate of 0.101 USD / TH / day
5 - Assume an average daily network hashrate of 116.73 EH

Mining and Dogecoin - Some FAQs

Hey shibes,
I see a lot of posts about mining lately and questions about the core wallet and how to mine with it, so here are some facts!
Feel free to add information to that thread or correct me if I did any mistake.

You downloaded the core wallet

Great! After a decade it probably synced and now you are wondering how to get coins? Bad news: You don't get coins by running your wallet, even running it as a full node. Check what a full node is here.
Maybe you thought so, because you saw a very old screenshot of a wallet, like this (Version 1.2). This version had a "Dig" tab where you can enter your mining configuration. The current version doesn't have this anymore, probably because it doesn't make sense anymore.

You downloaded a GPU/CPU miner

Nice! You did it, even your antivirus system probably went postal and you started covering all your webcams... But here is the bad news again: Since people are using ASIC miners, you just can't compete with your CPU hardware anymore. Even with your more advanced GPU you will have a hard time. The hashrate is too high for a desktop PC to compete with them. The blocks should be mined every 1 minute (or so) and that's causing the difficulty to go up - and we are out... So definitly check what is your hashrate while you are mining, you would need about 1.5 MH/s to make 1 Doge in 24 hours!

Mining Doge

Let us start with a quote:
"Dogecoin Core 1.8 introduces AuxPoW from block 371,337. AuxPoW is a technology which enables miners to submit work done while mining other coins, as work on the Dogecoin block chain."
- langerhans
What does this mean? You could waste your hashrate only on the Dogecoin chain, probably find never a block, but when, you only receive about 10.000 Dogecoins, currently worth about $25. Or you could apply your hashrate to LTC and Doge (and probably even more) at the same time. Your change of solving the block (finding the nonce) is your hashrate divided by the hashrat in sum - and this is about the same for Doge and LTC. This means you will always want to submit your work to all chains available!

Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or $2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

Buying an ASIC

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per $ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you $54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.
Thanks for reading
