Bitcoin Code Review 2020, Scam App! Scam Crypto Robots

PSA: Tachyon VPN appears to be a scam

Hi all,
I've been looking around for VPNs on mobile since I'm travelling these days and have stumbled over the emerging decentralized VPN approaches I found interesting. Two of those would be Tachyon or Orchid. This post is about Tachyon.
Since VPNs can easily be an attack vector, I was doing a bit of research but only found a few conclusive reviews about Tachyon (besides prominent hype articles). Nothing too bad neither but usually just some doubt in the independent reviews I've seen. They seem to have a rapidly growing userbase though and quite a few downloads on Google Play Store (500k+). They do offer a GitHub repo which I sifted through but didn't find comprehensive at first glance. I'm not qualified to judge the code though.
But what really raised my suspicion was that their official subreddit seems to be very ingenuine. The posts are your standard advertising, which is fair. But the comments, so I'm convinced, are altogether posted by bots. All comments share the same one- or two-sentence structure, are all very positive, don't interact, and come from people who's post history only consists of hyping some bitcoin stuff.
If you compare it to other subreddits of apps that could potentially pose some security threat like YouTube Vanced (for being an out-of-Play-Store-App), the difference is striking. You'll find some genuine discussions there.
So why would a genuine app that's built on trust and is as security-sensitive as a VPN find themselves with such a subreddit? It certainly raised my suspicion - if you have got any (opposing?) information about Tachyon VPN I'd be happy to hear about it.

TL;DR: The official Tachyon VPN subreddit consists of bots. I wouldn't trust that app.
Edit: Rhea-Tachyon has come back with a reply. I've linked it here since the downvotes pushed it below the visibility threshold.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

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

Hello Reddit and Ethereum community!

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

Executive summary

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

Response and PoC

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

Live Demo

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

Source Code

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

Scaling

How it works & scales

Architectural Scaling

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

Economic Scaling

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

Scaled Deployment

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

Flexibility in Scaling

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

Cost

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

Getting Started

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

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

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

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

Costs and resources

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

Requirements

Scaling

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

Decentralization

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

Usability Scaling solutions should have a simple end user experience.

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

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

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

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

Bonus Points

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

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

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

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

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

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

Bonus

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

TIME

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

Dragon Den

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

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

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

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

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

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

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

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

Other Considerations

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

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

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

Conclusion

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

Disney Releases Blockchain Platform as Open Source

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

Open Source

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

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Evidence that the mods of /r/Bitcoin may have been involved with the hacking and vote manipulation "attack" on /r/Bitcoin.

While running the Censorship Notifier Bot, we generally try to stay out of any specific situations regarding any subreddits we monitor. But the very nature of the CNBot requires it to collect and store large amounts of data, and requires us to be aware of normal trends within a subreddit to ensure the bot is running correctly. Specifically, the bot needs to know exactly what was on the site at a specific time, and when things disappear from the site. This data positions us to diligently analyze events and check real data as we go. When we first began looking at the massive downvoting attack as shown in BashCo's previously stickied thread last week, the first thing we noticed was that both of the bot-voted comments ( Image of #1, link to #2 ) would normally trigger our censorship notifier detection. Both "censoring" and "censorship" are trigger words we have found triggering automatic removal, something we later confirmed again. This would imply that either the comments were explicitly approved by the moderators at that time, or our understanding of the subreddit's policies needed updating. We began to dig into the data available, and those findings lead us to the conclusion that we must publish what we had found. Note: All times are in UTC; Some references are moved to the end of the document, tagged as [REF-1], [REF-2], etc.

Overview

We'll start out by giving a rough picture of the events that transpired. The bots which were downvoting comments and posts on /Bitcoin and upvoting posts on /btc began their attack on 11/14/2017 at around 18:00 utc. A similar unusual pattern of voting appeared on /btc around the same time the day before, though less dramatically. The bots seemed to be pushing people to buy Bitcoin Cash in such a blatant way that it even left a bad taste in the mouths of Bitcoin Cash supporters. Both the attack the day before and the /Bitcoin bot voting attack on 11/14/2017 ended before or around 22:00 utc [REF-3]. The bots attacking /Bitcoin upvoted posts complaining about high fees and downvoted about 30 other /Bitcoin posts. At the same time they upvoted posts on /btc. We identified 65 comments downvoted by bots in /Bitcoin and 2 upvoted. The conclusions appeared to indicate that the bots were promoting Bitcoin Cash and /btc and harming /Bitcoin.

Suspicious comment #1

We began investigating into the comments that caught our eye at first, referred to as [CU-1] and [CU-2] for short. [CU-1]'s content can be seen here as it originally looked. Immediately we noticed the next oddity - How were people able to see votes in /Bitcoin to discuss voting in the first place? /Bitcoin has blocked votes from being visible on comments during discussion for years. When did that change? We found that it changed right before [CU-1] was posted. BashCo stickied a comment stating they would "pull back the curtains" at 20:49, and archive.org confirmed that scores became visible between 20:32 utc and 20:50 utc. That, oddly enough, was just 13 minutes before [CU-1] was posted at 21:02:25.
We have determined that [CU-1] was indeed blocked by /Bitcoin's automoderator rules as we expected. The screenshot taken by /Bitcoin moderator StopAndDecrypt clearly shows this, as the "moderator approved" checkmark is present. We also tested automoderator rules with an aged account with karma and confirmed that "censors" and "censoring" were both blocked [REF-1]. Note that the poster, darwin2500 (under control of hacker, please don't ping them; they aren't a Bitcoiner) could not have been an "approved submitter" - they seem to have only had one comment in /Bitcoin before the hacking. So why was the comment manually approved? We are not aware of any other approved or allowed comments that blatantly reference censorship like that in the last several months. The obvious answer is that after "pulling back the curtain" and making votes visible, the /Bitcoin mods wanted to give people an opportunity to see this voting manipulation in action.
Except this idea did not hold up. We found 10 similar comments from the same time period which were not approved or were explicitly removed unlike [CU-1]. Some of these were uncannily similar to the original comment. For example this one was submitted 8 minutes after [CU-1] and never approved. Another here supported neither subreddit and was blocked at 21:48 and never approved. This one accused /Bitcoin mods of being paid by Blockstream and was manually removed at ~22:35. A fourth was identical to [CU-2] and blocked at 00:12 and never approved. The same account of [CU-1] submitted a second comment 5 minutes after [CU-1] and was blocked and not approved. The other 5 things blocked or removed around the same time were: [1] [2] [3] [4] [5]. The existence or absence of most of these comments around the claimed time can be verified independently of the censorship_notifier, see [REF-2]
But the why wasn't the only oddity. [CU-1] was submitted, approved, upvoted, and screenshotted all in less than 180 seconds, as shown by its screenshot ("2 minutes" rounds down on Reddit). That is an extremely short time for an automoderated comment to be approved based on what we have observed and in checking other subreddits open modlogs on approvals. Perhaps the moderators were very snappy about approving comments within this particular thread? Once again, this idea did not hold up. This comment appears to have been manually approved as it wasn't seen until the third scan after its supposed creation, ~11 minutes of delay. Perhaps only when the comment was a direct reply to BashCo? Still no - Here's a comment that was a direct reply to BashCo, but didn't show up in scans for 45 minutes. Here specifically the our data can be independently checked - This snapshot does not show the comment, but this one does.
Despite all the comments being blocked or removed as normal that we found, what we did not find was any other examples of anti-Bitcoin comments approved or allowed except the comments the bots upvoted. Three snapshots([1] [2] [3]) of the thread in question show no other strongly anti-Bitcoin comments present except [CU-1] and [CU-2]; Why did the moderators specifically allow [CU-1] and [CU-2] and nothing else? Perhaps they wanted to reveal the voting patterns, but then why only those comments? Further, by the time of [CU-1], the bot had not upvoted any comments at all. Why would the moderators assume that particular comment and no others would be upvoted, a mere 13 minutes after they "pulled back the curtain?"
In addition to the data we're referenced, our claims about the moderation of [CU-1] can be verified by either the admins or any current moderators of /Bitcoin, as moderator log events cannot be deleted. If anyone sends us an image of the moderator who approved this comment(preferably with full HH:MM:SS timestamp!) we will add the image to this post and keep their identity anonymous.

How did the bots pick targets?

The next thing we investigated was the behavior of the bots during the "attack". How many posts and comments did they downvote? How many did they upvote? What did they pick and were there any obvious correlations? We initially identified only two posts inside /Bitcoin that were upvoted by the bots - Both being posts about long delays on the OP's transaction confirmations. The first post was removed by moderators but otherwise no one seemed to notice the sudden upvotes. The second post upvoted on the other hand had users commenting on the upvotes within 8 minutes of it being posted and had several comments downvoted within it by the bots. Generally (but not always) the targets of the bots got 200-250 votes, either up or down [REF-3]. Even before the moderators of /Bitcoin revealed comment scores, users were commenting on the obviousness of the downvotes (edits). We found images from hacked users which showed what posts the bots chose to upvote and downvote, which further helped us identify as many of the posts as possible [REF-4] [REF-5].
The comments upvoted, too, were specifically chosen. Both comments upvoted were ones attacking /Bitcoin over censorship, and without any subtlety. Both comments were in the primary stickied thread with most of the comment downvotes. We quickly determined that the account that posted [CU-1] was under the control of the hacker, something other users also concluded. [CU-2] was posted by a clear /Bitcoin supporter based on history. Both comments used words that /Bitcoin's automod rules normally silently block [REF-1]. Other comments that subtly denigrated the subreddit's policies were noticed by the bot - but were downvoted instead of upvoted. Why?
The comments and posts chosen for downvoting were all over the place. Many of the comments chosen for downvoting seems to have been simply "because they were there in the thread" - For example every single comment visible in before 20:50 was downvoted. BashCo was targeted more than any other user(8 comments), but the bot generally didn't seem to focus on specific users. The vast majority of comments downvoted(54/65) happened in the stickied post, with 6 more happening in the second upvoted post. The remaining 5 comments downvoted were scattered across 4 different posts [REF-3]. The bot specifically went after comments and posts talking about downvotes, the accounts hack, or the attack itself [REF-5] but they also downvoted neutral posts. The voting seemed to come almost exclusively in waves targeting one thing at a time, which made the bot votes obvious to anyone who was looking for them - which people were, since many posts targeted were about the downvotes.
We also noticed that an extremely high number of /Bitcoin and /btc users were reporting that they themselves were hacked and part of the bot attack. We identified 35 such users, but the highest number of votes seen on a single thing indicate between 250-300 accounts involved with the attack. Over 10% of the hacked users were Bitcoiners, what are the chances of that? Well, Reddit has (very) roughly 50 million accounts, and the CN database indicates that about ~50k are regular or semi-regular /Bitcoin and /btc users, which is 1/1000th. 35 / 300 of hacked users being regular Bitcoin users and feeling the need to post about it is > 1/10th. Whoever was running this bot seems to have intentionally chosen Bitcoin users - It seems like they wanted the hacked users to see the results of the hack.
The result of all of this was that many many people commented on the blatantness of the voting, with many of them suspicious as to why anyone would do such a blatant attack. More examples: [1] [2] [3] [4] [5] [6] [7] [8] [9]. Amidst all of this there was one exception so subtle that we almost missed it - There were two posts voted on that ran completely contrary to the rest of the behavior of the bot. The first image showed upvotes on a pro-/Bitcoin post "PSA: Attack on Bitcoin" thread and a downvote for the anti-/Bitcoin "awkward meme orgy" /btc thread. At first we thought maybe this was a legitimate vote by this user mixed in with bot votes, but archive.org showed us that indeed that /btc thread got a sudden wave of downvotes in less than 23 minutes. Perhaps the bot forgot which side it was pushing for? But both changes were subtle and not noticed by any users as far as we can tell.
The final thing the bot did as far as we have identified was to upvote [CU-2], and then the attack seems to have stopped suddenly. That comment wasn't upvoted until 21:55 - 22:05. So what about that comment? Why was that the only comment not under its own control upvoted, and why did the attack stop suddenly afterwards?

Suspicious comment #2

The CN database gave us some hints. Both the [CU-2] and this comment were deleted by the user, likely when they took back control over their hacked account. [CU-1] was deleted at 21:23 +/- 1 minute, ~21 minutes after creation [REF-6], and not present in that snapshot. The votebot operator probably didn't expect this to happen so quickly. After that deletion there was no obvious comment showing their upvotes on the thread, and there were no obvious choices to choose from. It seems that they wanted a comment that wouldn't vanish, so not a hacked account, and also that they preferred a comment that could ultimately be used to make /btc look guilty.
4n4n4's comment [CU-2] provided exactly this, and it was posted to the thread ~5 minutes after [CU-1] was deleted - at 21:28. [CU-2] was never blocked by automoderator, it was picked up in the next CN scan ~1 minute later... Seemingly because 4n4n4 is an approved submitter. They have a long history of pro-/Bitcoin comments; we archived 5 pages of comments. The moderators left the comment in place and the bot didn't touch it for at least 27 minutes. With the similarities listed above, [CU-2] made the ideal next target for the bot's upvoting. Almost immediately after it did so, 4n4n4 screenshotted, archived, and edited the comment. And then the bot's voting attack instantly ceased as far as we can tell [REF-3] [REF-5].
But 4n4n4 was not a hacked account. So who is 4n4n4?

So who posted that?

We have a surprisingly large amount of evidence indicating that 4n4n4 is nullc, the CTO of Blockstream.
The biggest indicator we found is that nullc has the very frequent pattern-- of writing--his sentences with two dashes separating words. This by itself is somewhat rare, though we confirmed that he uses it more times than anyone else in the CN database, the much more unusual habit is using two dashes with no spaces on either side. The CN database stored 860,000 comments for us to compare with, and very quickly confirmed the similarities between the two. His history is littered with examples, but we also used the bitcoin-dev email list to confirm the unusual habit. Like 4n4n4, nullc also has examples of using this--specific pattern twice in one sentence, which was extremely rare in our searches.
But there were many more things we noticed. We found several examples of 4n4n4 picking up nullc's conversations and continuing them. One such case was 4n4n4's third comment ever. 4n4n4 also referenced many of nullc's writings and posts. 4n4n4 referenced this code change that originated from nullc multiple times. 4n4n4's [CU-2] comment edit used the words "rbtc playbook," something our database confirmed was extremely rare but is a saying nullc likes.
And that was just the beginning:
  1. Very knowledgable about Bitcoin Core development & the history of the scaling conflict.
  2. 4n4n4 picked up a thread after many replies by nullc arguing that low fees and empty mempools are actually a problem.
  3. Just like nullc, 4n4n4 liked BIP148 but did not "support" or "endorse" it.
  4. Seems to know an awful lot about nullc's life.
  5. Used the phrase "Bitcoin's creator", a major nullc trait previously documented
  6. Talks about nullc. A lot.
  7. Somehow knows who is working on what within Blockstream.
  8. And even responded directly to nullc in support of a claim nullc had made multiple times within that thread

Conclusions

After the massive amount of research we put into this, we believe that at least one moderator of /Bitcoin must have been either aware of the bot's plans (and allowed it to place blame on others), or have executed the attack themselves. This is most likely the moderator who immediately approved the [CU-1] comment. Other moderators may or may not have been involved. Meaning, yes, we believe that a moderator of /Bitcoin either directed or was complicit in the hacking of many of their own Bitcoin Reddit user accounts.
We believe that it is likely that 4n4n4 aka nullc was also aware of or involved in this attack based upon the suspicious timing and similarities of [CU-2]. A Core Developer of nullc's experience would certainly have the technical abilities to pull off such an attack, but that is true of many others on both sides of the debate as well. Some users reported that the IP addresses the bots logged in from were vultr instances and that vultr 1) requires tracable payment methods like credit cards, and 2) takes an aggressive stance against abuse of their systems, so perhaps more information can come to light about this yet.
We encourage the Reddit admins to carefully review our claims and to validate them. If our claims here are true, surely some type of strong action is warranted. Please note that we have tried to make sure all of our links are archived, but they were archived under the www.reddit.com domain and not the np.reddit.com domain.
For any people who found this post helpful and want to tip us, please donate your tips to archive.is and archive.org (not us). Without those two amazing services none of this research would be possible.
