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.

Major Exchanges
In finance, an exchange is a forum or platform for trading commodities, derivatives, securities or other financial instruments. The principle concern of an exchange is to allow trading between parties to take place in a fair and legally compliant manner, as well as to ensure that pricing information for any instrument traded on the exchange is reliable and coherently delivered to exchange participants. In the cryptocurrency space exchanges are online platforms that allow users to trade cryptocurrencies or digital currencies for fiat money or other cryptocurrencies. They can be centralized exchanges such a Binance, or decentralized exchanges such as IDEX. Most cryptocurrency exchanges allow users to trade different crypto assets with BTC or ETH after having already exchanged fiat currency for one of those cryptocurrencies. Coinbase and Kraken are the main avenue for fiat money to enter into the cryptocurrency ecosystem.
Function and History
Crypto exchanges can be market-makers that take bid/ask spreads as a commission on the transaction for facilitating the trade, or more often charge a small percentage fee for operating the forum in which the trade was made. Most crypto exchanges operate outside of Western countries, enabling them to avoid stringent financial regulations and the potential for costly and lengthy legal proceedings. These entities will often maintain bank accounts in multiple jurisdictions, allowing the exchange to accept fiat currency and process transactions from customers all over the globe.
The concept of a digital asset exchange has been around since the late 2000s and the following initial attempts at running digital asset exchanges foreshadows the trouble involved in attempting to disrupt the operation of the fiat currency baking system. The trading of digital or electronic assets predate Bitcoin’s creation by several years, with the first electronic trading entities running afoul of the Australian Securities and Investments Commission (ASIC) in late 2004. Companies such as Goldex, SydneyGoldSales, and Ozzigold, shut down voluntarily after ASIC found that they were operating without an Australian Financial Services License. E-Gold, which exchanged fiat USD for grams of precious metals in digital form, was possibly the first digital currency exchange as we know it, allowing users to make instant transfers to the accounts of other E-Gold members. At its peak in 2006 E-Gold processed $2 billion worth of transactions and boasted a user base of over 5 million people.
Popular Exchanges
Here we will give a brief overview of the features and operational history of the more popular and higher volume exchanges because these are the platforms to which newer traders will be exposed. These exchanges are recommended to use because they are the industry standard and they inspire the most confidence.
Bitfinex
Owned and operated by iFinex Inc, the cryptocurrency trading platform Bitfinex was the largest Bitcoin exchange on the planet until late 2017. Headquartered in Hong Kong and based in the US Virgin Island, Bitfinex was one of the first exchanges to offer leveraged trading (“Margin trading allows a trader to open a position with leverage. For example — we opened a margin position with 2X leverage. Our base assets had increased by 10%. Our position yielded 20% because of the 2X leverage. Standard trades are traded with leverage of 1:1”) and also pioneered the use of the somewhat controversial, so-called “stable coin” Tether (USDT).
Binance
Binance is an international multi-language cryptocurrency exchange that rose from the mid-rank of cryptocurrency exchanges to become the market dominating behemoth we see today. At the height of the late 2017/early 2018 bull run, Binance was adding around 2 million new users per week! The exchange had to temporarily disallow new registrations because its servers simply could not keep up with that volume of business. After the temporary ban on new users was lifted the exchange added 240,000 new accounts within two hours.
Have you ever thought whats the role of the cypto exchanges? The answer is simple! There are several different types of exchanges that cater to different needs within the ecosystem, but their functions can be described by one or more of the following: To allow users to convert fiat currency into cryptocurrency. To trade BTC or ETH for alt coins. To facilitate the setting of prices for all crypto assets through an auction market mechanism. Simply put, you can either mine cryptocurrencies or purchase them, and seeing as the mining process requires the purchase of expensive mining equipment, Cryptocurrency exchanges can be loosely grouped into one of the 3 following exchange types, each with a slightly different role or combination of roles.
Have you ever thought about what are the types of Crypto exchanges?
  1. Traditional Cryptocurrency Exchange: These are the type that most closely mimic traditional stock exchanges where buyers and sellers trade at the current market price of whichever asset they want, with the exchange acting as the intermediary and charging a small fee for facilitating the trade. Kraken and GDAX are examples of this kind of cryptocurrency exchange. Fully peer-to-peer exchanges that operate without a middleman include EtherDelta, and IDEX, which are also examples of decentralized exchanges.
  2. Cryptocurrency Brokers: These are website or app based exchanges that act like a Travelex or other bureau-de-change. They allow customers to buy or sell crypto assets at a price set by the broker (usually market price plus a small premium). Coinbase is an example of this kind of exchange.
  3. Direct Trading Platform: These platforms offer direct peer-to-peer trading between buyers and sellers, but don’t use an exchange platform in doing so. These types of exchanges do not use a set market rate; rather, sellers set their own rates. This is a highly risky form of trading, from which new users should shy away.
To understand how an exchange functions we need only look as far as a traditional stock exchange. Most all the features of a cryptocurrency exchange are analogous to features of trading on a traditional stock exchange. In the simplest terms, the exchanges fulfil their role as the main marketplace for crypto assets of all kinds by catering to buyers or sellers. These are some definitions for the basic functions and features to know: Market Orders: Orders that are executed instantly at the current market price. Limit Order: This is an order that will only be executed if and when the price has risen to or dropped to that price specified by the trader and is also within the specified period of time. Transaction fees: Exchanges will charge transactions fees, usually levied on both the buyer and the seller, but sometimes only the seller is charged a fee. Fees vary on different exchanges though the norm is usually below 0.75%. Transfer charges: The exchange is in effect acting as a sort of escrow agent, to ensure there is no foul play, so it might also charge a small fee when you want to withdraw cryptocurrency to your own wallet.
Regulatory Environment and Evolution
Cryptocurrency has come a long way since the closing down of the Silk Road darknet market. The idea of crypto currency being primarily for criminals, has largely been seen as totally inaccurate and outdated. In this section we focus on the developing regulations surrounding the cryptocurrency asset class by region, and we also look at what the future may hold.
The United States of America
A coherent uniform approach at Federal or State level has yet to be implemented in the United States. The Financial Crimes Enforcement Network published guidelines as early as 2013 suggesting that BTC and other cryptos may fall under the label of “money transmitters” and thus would be required to take part in the same Anti-money Laundering (AML) and Know your Client (KYC) procedures as other money service businesses. At the state level, Texas applies its existing finance laws. And New York has instituted an entirely new licensing system.
The European Union
The EU’s approach to cryptocurrency has generally been far more accommodating overall than the United States, partly due to the adaptable nature of pre-existing laws governing electronic money that predated the creation of Bitcoin. As with the USA, the EU’s main fear is money laundering and criminality. The European Central Bank (ECB) categorized BTC as a “convertible decentralized currency” and advised all central banks in the EU to refrain from trading any cryptocurrencies until the proper regulatory framework was put in place. A task force was then set up by the European Parliament in order to prevent and investigate any potential money laundering that was making use of the new technology.
Likely future regulations for cryptocurrency traders within the European Union and North America will probably consist of the following proposals: The initiation of full KYC procedures so that users cannot remain fully anonymous, in order to prevent tax evasion and curtail money laundering. Caps on payments that can be made in cryptocurrency, similar to caps on traditional cash transactions. A set of rules governing tax obligations regarding cryptocurrencies Regulation by the ECB of any companies that offer exchanges between cryptocurrencies and fiat currencies It is less likely for other countries to follow the Chinese approach and completely ban certain aspects of cryptocurrency trading. It is widely considered more progressive and wiser to allow the technology to grow within a balanced accommodative regulatory framework that takes all interests and factors into consideration. It is probable that the most severe form of regulation will be the formation of new governmental bodies specifically to form laws and exercise regulatory control over the cryptocurrency space. But perhaps that is easier said than done. It may, in certain cases, be incredibly difficult to implement particular regulations due to the anonymous and decentralized nature of crypto.
Behavior of Cryptocurrency Investors by Demographic
Due to the fact that cryptocurrency has its roots firmly planted in the cryptography community, the vast majority of early adopters are representative of that group. In this section we cover the basic structure of the cryptocurrency market cycle and the makeup of the community at large, as well as the reasons behind different trading decisions.
The Cryptocurrency Market Cycle
Bitcoin leads the bull rally. FOMO (Fear of missing out) occurs, the price surge is a constant topic of mainstream news, business programs cover the story, and social media is abuzz with cryptocurrency chatter. Bitcoin reaches new All Timehigh (ATH) Market euphoria is fueled with even more hype and the cycle is in full force. There is a constant stream of news articles and commentary on the meteoric, seemingly unstoppable rise of Bitcoin. Bitcoin’s price “stabilizes”, In the 2017 bull run this was at or around $14,000. A number of solid, large market cap altcoins rise along with Bitcoin; ETH & LTC leading the altcoins at this time. FOMO comes into play, as the new ATH in market cap is reached by pumping of a huge number of alt coins.
Top altcoins “somewhat” stabilize, after reaching new all-time highs. The frenzy continues with crypto success stories, notable figures and famous people in the news. A majority of lesser known cryptocurrencies follow along on the upward momentum. Newcomers are drawn deeper into crypto and sign up for exchanges other than the main entry points like Coinbase and Kraken. In 2017 this saw Binance inundated with new registrations. Some of the cheapest coins are subject to massive pumping, such as Tron TRX which saw a rise in market cap from $150 million at the start of December 2017 to a peak of $16 billion! At this stage, even dead coins or known scams will get pumped. The price of the majority of cryptocurrencies stabilize, and some begin to retract. When the hype is subsiding after a huge crypto bull run, it is a massive sell signal. Traditional investors will begin to give interviews about how people need to be careful putting money into such a highly volatile asset class. Massive violent correction begins and the market starts to collapse. BTC begins to fall consistently on a daily basis, wiping out the insane gains of many medium to small cap cryptos with it. Panic selling sweeps through the market. Depression sets in, both in the markets, and in the minds of individual investors who failed to take profits, or heed the signs of imminent collapse. The price stagnation can last for months, or even years.
The Influence of Age upon Trading
Did you know? Cryptocurrencies have been called “stocks for millennials” According to a survey conducted by the Global Blockchain Business Council, only 5% of the American public own any bitcoin, but of those that do, an overwhelming majority of 71% are men, 58% of them are between the ages of 18 and 35, and over half of them are minorities. The same survey gauged public attitude toward the high risk/high return nature of cryptocurrency, in comparison to more secure guaranteed small percentage gains offered by government bonds or stocks, and found that 30% would rather invest $1,000 in crypto. Over 42% of millennials were aware of cryptocurrencies as opposed to only 15% of those ages 65 and over. In George M. Korniotis and Alok Kumar’s study into the effects of aging on portfolio management and the quality of decisions made by older investors, they found “that older and experienced investors are more likely to follow “rules of thumb” that reflect greater investment knowledge. However, older investors are less effective in applying their investment knowledge and exhibit worse investment skill, especially if they are less educated and earn lower income.”
Geographic Influence upon Trading
One of the main drivers of the apparent seasonal ebb and flow of cryptocurrency prices is the tax situation in the various territories that have the highest concentrations of cryptocurrency holders. Every year we see an overall market pull back beginning in mid to late January, with a recovery beginning usually after April. This is because “Tax Season” is roughly the same across Europe and the United States, with the deadline for Income tax returns being April 15th in the United States, and the tax year officially ending the UK on the 6th of April. All capital gains must be declared before the window closes or an American trader will face the powerful and long arm of the IRS with the consequent legal proceedings and possible jail time. Capital gains taxes around the world vary from jurisdiction to jurisdiction but there are often incentives for cryptocurrency holders to refrain from trading for over a year to qualify their profits as long term gain when they finally sell. In the US and Australia, for example, capital gains are reduced if you bought cryptocurrency for investment purposes and held it for over a year. In Germany if crypto assets are held for over a year then the gains derived from their sale are not taxed. Advantages like this apply to individual tax returns, on a case by case basis, and it is up to the investor to keep up to date with the tax codes of the territory in which they reside.
2013 Bull run vs 2017 Bull run price Analysis
In late 2016 cryptocurrency traders were faced with the task of distinguishing between the beginnings of a genuine bull run and what might colorfully be called a “dead cat bounce” (in traditional market terminology). Stagnation had gripped the market since the pull-back of early 2014. The meteoric rise of Bitcoin’s price in 2013 peaked with a price of $1,100 in November 2013, after a year of fantastic news on the adoption front with both Microsoft and PayPal offering BTC payment options. It is easy to look at a line going up on a chart and speak after the fact, but at the time, it is exceeding difficult to say whether the cat is actually climbing up the wall, or just bouncing off the ground. Here, we will discuss the factors that gave savvy investors clues as to why the 2017 bull run was going to outstrip the 2013 rally. Hopefully this will help give insight into how to differentiate between the signs of a small price increase and the start of a full scale bull run. Most importantly, Volume was far higher in 2017. As we can see in the graphic below, the 2017 volume far exceeds the volume of BTC trading during the 2013 price increase. The stranglehold MtGox held on trading made a huge bull run very difficult and unlikely.
Fraud & Immoral Activity in the Private Market
Ponzi Schemes Cryptocurrency Ponzi schemes will be covered in greater detail in Lesson 7, but we need to get a quick overview of the main features of Ponzi schemes and how to spot them at this point in our discussion. Here are some key indicators of a Ponzi scheme, both in cryptocurrencies and traditional investments: A guaranteed promise of high returns with little risk. Consistentflow of returns regardless of market conditions. Investments that have not been registered with the Securities and Exchange Commission (SEC). Investment strategies that are a secret, or described as too complex. Clients not allowed to view official paperwork for their investment. Clients have difficulties trying to get their money back. The initial members of the scheme, most likely unbeknownst to the later investors, are paid their “dividends” or “profits” with new investor cash. The most famous modern-day example of a Ponzi scheme in the traditional world, is Bernie Madoff’s $100 billion fraudulent enterprise, officially titled Bernard L. Madoff Investment Securities LLC. And in the crypto world, BitConnect is the most infamous case of an entirely fraudulent project which boasted a market cap of $2 billion at its peak.
What are the Exchange Hacks?
The history of cryptocurrency is littered with examples of hacked exchanges, some of them so severe that the operation had to be wound up forever. As we have already discussed, incredibly tech savvy and intelligent computer hackers led by Alexander Vinnik stole 850000 BTC from the MtGox exchange over a period from 2012–2014 resulting in the collapse of the exchange and a near-crippling hammer blow to the emerging asset class that is still being felt to this day. The BitGrail exchange suffered a similar style of attack in late 2017 and early 2018, in which Nano (XRB) was stolen that was at one point was worth almost $195 million. Even Bitfinex, one of the most famous and prestigious exchanges, has suffered a hack in 2016 where $72 million worth of BTC was stolen directly from customer accounts.
Hardware Wallet Scam Case Study
In late 2017, an unfortunate character on Reddit, going by the name of “moody rocket” relayed his story of an intricate scam in which his newly acquired hardware wallet was compromised, and his $34,000 life savings were stolen. He bought a second hand Nano ledger into which the scammers own recover seed had already been inserted. He began using the ledger without knowing that the default seed being used was not a randomly assigned seed. After a few weeks the scammer struck, and withdrew all the poor HODLer’s XRP, Dash and Litecoin into their own wallet (likely through a few intermediary wallets to lessen the very slim chances of being identified).
Hardware Wallet Scam Case Study Social Media Fraud
Many gullible and hapless twitter users have fallen victim to the recent phenomenon of scammers using a combination of convincing fake celebrity twitter profiles and numerous amounts of bots to swindle them of ETH or BTC. The scammers would set up a profile with a near identical handle to a famous figure in the tech sphere, such as Vitalik Buterin or Elon Musk. And then in the tweet, immediately following a genuine message, follow up with a variation of “Bonus give away for the next 100 lucky people, send me 0.1 ETH and I will send you 1 ETH back”, followed by the scammers ether wallet address. The next 20 or so responses will be so-called sockpuppet bots, thanking the fake account for their generosity. Thus, the pot is baited and the scammers can expect to receive potentially hundreds of donations of 0.1 Ether into their wallet. Many twitter users with a large follower base such as Vitalik Buterin have taken to adding “Not giving away ETH” to their username to save careless users from being scammed.
Market Manipulation
It also must be recognized that market manipulation is taking place in cryptocurrency. For those with the financial means i.e. whales, there are many ways in which to control the market in a totally immoral and underhanded way for your own profit. It is especially easy to manipulate cryptos that have a very low trading volume. The manipulator places large buy orders or sell walls to discourage price action in one way or the other. Insider trading is also a significant problem in cryptocurrency, as we saw with the example of blatant insider trading when Bitcoin Cash was listed on Coinbase.
Examples of ICO Fraudulent Company Behavior
In the past 2 years an astronomical amount of money has been lost in fraudulent Initial Coin Offerings. The utmost care and attention must be employed before you invest. We will cover this area in greater detail with a whole lesson devoted to the topic. However, at this point, it is useful to look at the main instances of ICO fraud. Among recent instances of fraudulent ICOs resulting in exit scams, 2 of the most infamous are the Benebit and PlexCoin ICOs which raised $4 million for the former and $15 million for the latter. Perhaps the most brazen and damaging ICO scam of all time was the Vietnamese Pincoin ICO operation, where $660million was raised from 32,000 investors before the scammer disappeared with the funds. In case of smaller ICO “exit scamming” there is usually zero chance of the scammers being found. Investors must just take the hit. We will cover these as well as others in Lesson 7 “Scam Projects”.
Signposts of Fraudulent Actors
The following factors are considered red flags when investigating a certain project or ICO, and all of them should be considered when deciding whether or not you want to invest. Whitepaper is a buzzword Salad: If the whitepaper is nothing more than a collection of buzzwords with little clarity of purpose and not much discussion of the tech involved, it is overwhelmingly likely you are reading a scam whitepaper.
Signposts of Fraudulent Actors §2
No Code Repository: With the vast majority of cryptocurrency projects employing open source code, your due diligence investigation should start at GitHub or Sourceforge. If the project has no entries, or nothing but cloned code, you should avoid it at all costs. Anonymous Team: If the team members are hard to find, or if you see they are exaggerating or lying about their experience, you should steer clear. And do not forget, in addition to taking proper precautions when investing in ICOs, you must always make sure that you are visiting authentic web pages, especially for web wallets. If, for example, you are on a spoof MyEtherWallet web page you could divulge your private key without realizing it and have your entire portfolio of Ether and ERC-20 tokens cleaned out.
Methods to Avoid falling Victim
Avoiding scammers and the traps they set for you is all about asking yourself the right questions, starting with: Is there a need for a Blockchain solution for the particular problem that a particular ICO is attempting to solve? The existing solution may be less costly, less time consuming, and more effective than the proposals of a team attempting to fill up their soft cap in an ICO. The following quote from Mihai Ivascu, the CEO of Modex, should be kept in mind every time you are grading an ICO’s chances of success: “I’m pretty sure that 95% of ICOswill not last, and many will go bankrupt. ….. not everything needs to be decentralized and put on an open source ledger.”
Methods to Avoid falling Victim §2 Do I Trust These People with My Money, or Not?
If you continue to feel uneasy about investing in the project, more due diligence is needed. The developers must be qualified and competent enough to complete the objectives that they have set out in the whitepaper.
Is this too good to be true?
All victims of the well-known social media scams using fake profiles of Vitalik Buterin, or Bitconnect investors for that matter, should have asked themselves this simple question, and their investment would have been saved. In the case of Bitconnect, huge guaranteed gains proportional to the amount of people you can get to sign up was a blatant pyramid scheme, obviously too good to be true. The same goes for Fake Vitalik’s offer of 1 ether in exchange for 0.1 ETH.
Selling Cryptocurrencies, Several reasons for selling with the appropriate actions to take:
If you are selling to buy into an ICO, or maybe believe Ether is a safer currency to hold for a certain period of time, it is likely you will want to make use of the Ether pair and receive Ether in return. Obviously if the ICO is on the NEO or WANchain blockchain for example, you will use the appropriate pair. -Trading to buy into another promising project that is listing on the exchange on which you are selling (or you think the exchange will experience a large amount of volume and become a larger exchange), you may want to trade your cryptocurrency for that exchange token. -If you believe that BTC stands a good chance of experiencing a bull run then using the BTC trading pair is the suitable choice. -If you believe that the market is about to experience a correction but you do not want to take your gains out of the market yet, selling for Tether or “tethering up” is the best play. This allows you to keep your locked-in profits on the exchange, unaffected by the price movements in the cryptocurrency markets,so that you can buy back in at the most profitable moment. -If you wish to “cash out” i.e. sell your cryptocurrency for fiat currency and have those funds in your bank account, the best pair to use is ETH or BTC because you will likely have to transfer to an exchange like Kraken or Coinbase to convert them into fiat. If the exchange offers Litecoin or Bitcoin Cash pairs it could be a good idea to use these for their fast transaction time and low fees.
Selling Cryptocurrencies
Knowing when and how to sell, as well as strategies to inflate the value of your trade before sale, are important skills as a trader of any product or financial instrument. If you are satisfied that the sale itself of the particular amount of a token or coin you are trading away is the right one, then you must decide at what price you are going to sell. Exchanges exercise their own discretion as to which trading “pairs” they will offer, but the most common ones are BTC, ETH, BNB for Binance, BIX for Bibox etc., and sometimes Tether (USDT) or NEO. As a trader, you decide which particular cryptocurrency to exchange depending on your reason for making that specific trade at that time.
Methods of Sale
Market sell/Limit sell on exchange: A limit sell is an order placed on an exchange to sell as soon as (also specifically only if and when) the price you specified has been hit within the time limit you select. A market order executes the sale immediately at the best possible price offered by the market at that exact time. OTC (or Over the Counter) selling refers to sale of securities or cryptocurrencies in any method without using an exchange to intermediate the trade and set the price. The most common way of conducting sales in this manner is through LocalBitcoins.com. This method of cryptocurrency selling is far riskier than using an exchange, for obvious reasons.
The influence and value of your Trade
There are a number of strategies you can use to appreciate the value of your trade and thus increase the Bitcoin or Ether value of your portfolio. It is important to disassociate yourself from the dollar value of your portfolio early on in your cryptocurrency trading career simply because the crypto market is so volatile you will end up pulling your hair out in frustration following the real dollar money value of your holdings. Once your funds have been converted into BTC and ETH they are completely in the crypto sphere. (Some crypto investors find it more appropriate to monitor the value of their portfolio in satoshi or gwei.) Certainly not limited to, but especially good for beginners, the most reliable way to increase your trading profits, and thus the overall value and health of your portfolio, is to buy into promising projects, hold them for 6 months to a year, and then reevaluate. This is called Long term holding and is the tactic that served Bitcoin HODLers quite well, from 2013 to the present day. Obviously, if something comes to light about the project that indicates a lengthy set back is likely, it is often better to cut your losses and sell. You are better off starting over and researching other projects. Also, you should set initial Price Points at which you first take out your original investment, and then later, at which you take out all your profits and exit the project. That should be after you believe the potential for growth has been exhausted for that particular project.
Another method of increasing the value of your trades is ICO flipping. This is the exact opposite of long term holding. This is a technique in which you aim for fast profits taking advantage of initial enthusiasm in the market that may double or triple the value of ICO projects when they first come to market. This method requires some experience using smaller exchanges like IDEX, on which project tokens can be bought and sold before listing on mainstream exchanges. “Tethering up” means to exchange tokens or coins for the USDT stable coin, the value of which is tethered to the US Dollar. If you learn, or know how to use, technical analysis, it is possible to predict when a market retreatment is likely by looking at the price movements of BTC. If you decide a market pull back is likely, you can tether up and maintain the dollar value of your portfolio in tether while other tokens and coins decrease in value. The you wait for an opportune moment to reenter the market.
Market Behavior in Different Time Periods
The main descriptors used for overall market sentiment are “Bull Market” and “Bear Market”. The former describes a market where people are buying on optimism. The latter describes a market where people are selling on pessimism. Fun (or maybe not) fact: The California grizzly bear was brought to extinction by the love of bear baiting as a sport in the mid 1800s. Bears were highly sought after for their intrinsic fighting qualities, and were forced into fighting bulls as Sunday morning entertainment for Californians. What has this got to do with trading and financial markets? The downward swipe of the bear’s paws gives a “Bear market” its name and the upward thrust of a Bull’s horns give the “Bull Market” its name. Most unfortunately for traders, the bear won over 80% of the bouts. During a Bull market, optimism can sometimes grow to be seemingly boundless, volume is rising, and prices are ascending. It can be a good idea to sell or rebalance your portfolio at such a time, especially if you have a particularly large position in one holding or another. This is especially applicable if you need to sell a large amount of a relatively low-volume holding, because you can then do so without dragging the price down by the large size of your own sell order.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.
