Companies like Microsoft, IDEO and IBM are working together to make a decentralized identity network. Some applications could be to inhibit voter suppression and vote manipulation/hacking for elections. I heard Bitcoin was going to be used as the blockchain to do this.

What are your thoughts on Bitcoin vs Ethereum vs altcoins?

The crypto markets are hot again.
The investor chat still tends to revolve around Bitcoin, but if you hang around in cryptocurrency forums, the chat is more focused on Ethereum and DeFi (which is mainly built on top of Ethereum). Altcoins are still around but they don't get much attention.
What does /investing thing of Bitcoin vs Ethereum?
I'm not asking what your opinion of the crypto markets is in general, but your opinion on one crypto asset relative to the other.
Do you have strong opinions on any altcoins (cryptocurrencies other then Bitcoin and Ethereum)?

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low

Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.

Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.

XMR Atomic Swaps Now Support PART | Anonymous Decentralized Marketplace Integration Coming Soon

XMR Atomic Swaps Now Support PART | Anonymous Decentralized Marketplace Integration Coming Soon
Hey guys,
Cryptoguard from Particl here. We're happy to announce that we've recently added PART atomic swap support to the xmr-btc-atomic-swap protocol on mainnet and have pushed the protocol on Particl's Github.
The ability to atomically swap XMR <> PART opens up a lot of doors for the advancement of anonymous eCommerce solutions and solidifies the sustainability and resiliency of decentralized marketplaces, a strong win for all proponents of free market, personal freedom, and self-determination.
For those not aware of Particl, it is Bitcoin-based blockchain (currently 0.19.1.1, about to release 0.20) with a native currency (PART) that has a variable level of privacy (public, blind (CT), and anon (RingCT)).
We've built a completely decentralized, trustless, and unstoppable marketplace where you can buy and sell anything online without using any third-party, without paying any fee (other than regular crypto transactions), and without leaving any sort of digital footprint behind. The entire marketplace experience, just like its transactions/sales, is private by default thanks to a combination of CT, RingCT, stealth addresses, Tor, SecureMessaging/BitMessage, and etc. The marketplace has been on mainnet for a year now, as an open Beta, and we're about to push our biggest update since launch—a brand new desktop application as well as a completely refactored marketplace. This will dramatically improve the user experience and the performance, making the private decentralized marketplace as user-friendly as it's ever been.
We now plan on adding native XMR <> PART swap support into the desktop client and marketplace application, allowing anyone holding XMR to easily buy and sell anything on a decentralized marketplace that respects your privacy. It also ensures that you can now get in and out of Particl's ecosystem without having to go through any third-party such as an exchange or payment processor.
XMR <> PART support will add a tremendous level of privacy to the marketplace and expand on what's possible to do now with Monero.
Here's a mockup of what an XMR <> PART swap engine may look like in Particl Desktop's Swap module (independent module from the marketplace).
WIP, not a screenshot but a mock up, final look may differ
Additionally, we're equally happy to announce that we will be adding XMR <> PART support to the marketplace and Particl Desktop application as soon as Particl V3, the upcoming massive release, is out on mainnet. The integration will use both StealthEX and SimpleSwap exchanges to provide you with an easy way to swap coins before atomic swaps are pushed to the client, once ready.
---
We'd like to thank everyone involved in the development of the XMR <> BTC swap protocol that made this possible, especially h4sh3d for cracking the code on how to execute an XMR <> BTC atomic swap and the Monero community for funding the research.
The ability to swap XMR and BTC together is probably one of the biggest wins in crypto since the last few years, and we're super excited to see all that's going to be possible from now on. Let's keep pushing crypto forward and make it as private as it should!

IamA Founder of HOPR a pioneering data privacy project. My name is Dr. Sebastian Bürgel - AMA

HOPR Team Foreword: Dr. Sebastian Bürgel received his PhD from ETH Zurich, one of the world's top 10 universities for Science and Technology, before becoming an entrepreneur and architect of decentralized blockchain applications. His technical know-how helped shape the Distributed Ledger Technology (DLT) Law of Switzerland. Previously, Dr. Bürgel co-founded Validity Labs, the first Swiss blockchain education and service company, and taught the former Swiss President, Johann Schneider-Ammann, his first blockchain lesson.
Dr. Bürgel also co-founded SONECT, a fintech startup that developed a widely-used virtual ATM network.
In His Own Words: I have dedicated my career to building technical solutions that empower the individual.
I am contributing to a privacy-first web3 with HOPRnet.org, a blockchain-based data privacy project I founded, where we are taking a positive and empowering approach to providing network-level data privacy for all. We are also incentivizing everyone – not just those with technical experience – to relay data (which masks sender and recipient) by running a HOPR node and earning HOPR tokens.
Privacy is a major topic for the web3, powering the next generation of web applications, platforms and services. I am also interested in the future of work towards a post-corporate era. Do humans need companies to create value? Digital organizations such as DAOs (decentralized autonomous organizations) are a major shift away from traditional employment, organizations and the way we work.
Before joining the blockchain and crypto ecosystem, I worked as a postdoctoral fellow and PhD student at ETH Zurich in the domain of microtechnology and microfabrication for biomedical applications such as drug discovery, cancer research and neglected tropical diseases.
I am happy to engage in discussions and support people who #buidl:

CEO KardiaChain Tri Pham - Aspiration for every Vietnamese person to own tokens.

At the beginning of last year, a Vietnamese Startup announced the successful construction of a multi-connected blockchain system called KardiaChain.In particular, recently KardiaChain officially launched a cooperation deal with Mai Linh Group to promote the use of KAI tokens into life.
To better understand the mission of bringing Blockchain technology closer to the Vietnamese people, Beincrypto had the opportunity to interview Mr. Tri Pham - CEO of KardiaChain about the views and spirit that KardiaChain wants in the present and in the future. With the wish that every citizen owns tokens and realizes the huge potential of the Vietnamese market when the government and businesses still do not have a decentralized technology platform, Mr. Tri Pham and his colleagues have decided to quit his job in the UK to return to Vietnam to settle down.
Reporter: As an entrepreneur with a dream career in the UK, why did you decide to return to Vietnam to build a blockchain startup. Do you feel that Vietnamese people are embracing Blockchain technology?
Honestly, when my family knew I was doing blockchain or crypto, it was very frustrating. Because in Vietnam, hearing about Blockchain or Bitcoin thinks it is virtual money, so it is very shy. Businesses take a long time to learn about this technology. In the West, they already have solid information networks, technology systems, and digitalization available so when applying Blockchain will not add much value. In Vietnam, digital information system has not been widely applied, so it will be easier to apply a new technology. The next potential lies in the large Vietnamese population, a large number of young people, the high rate of mobile phone usage, and the rapid ability to access new information. I used to work and start a business in the technology field, so I want to build a blockchain infrastructure for Vietnam. I am a Vietnamese, so I always look to my homeland and want to bring products of genuine value to Vietnam.
Reporter: Recently, KardiaChain has created an echo when cooperating with Mai Linh. How do you feel when you combine with Mai Linh group?
Director of Mai Linh used to be a soldier, so he has a national spirit and wants to help Vietnamese people extremely. I see in Mai Linh that they are very humane, working I feel consistent with my values. The two sides have similarities in their goals and visions for a better Vietnamese society, so it's easy to work and they get a lot of support.
Reporter: In the past, Kardiachain focused a lot on serving Government objects, businesses but not C2C, but what about now?
What I want is that every Vietnamese person has KAI tokens in their possession. But to do this is really difficult because Blockchain technology itself is very complex, to ordinary people it is invisible, because they cannot see. One just needs to know "Ah! I have the token, how do I spend ". The goal of KardiaChain (KAI) is to bring a lot of value to the user, one does not need to know the underlying technology, one only needs to know the applications so they get used to owning and using tokens. I choose to approach businesses and organizations that own existing Customer files, with large data, the token will reach more users. Cooperation with businesses like Mai Linh or carriers like Viettel to bring tokens to many benefits for use in real life and that everyone can accept and easily use.
Reporter: Coming up is the highly anticipated Mainnet event of KAI. What steps have you taken to prepare for a successful Mainnet launch?
KardiaChain launched quite a few products starting at the end of 2018. While building infrastructure for Mainnet, KardiaChain contacted business parties in many other fields to know what they need to do to solve their business problems. industry has no answer. Through many times I have tested and run many products, I have recently selected only a few as key products. For example, a product that allows users to use tokens to vote, especially in the sports and game fields. Blockchain is decentralized, so it must be community-based, votes and votes must be trusted.
Recently, KardiaChain also launched KAIstarter as a DeFi platform for KAI holders to invest in traditional businesses and earn stable profits and businesses also take advantage of a source to call a transparent investment fund. benefits for both parties.
Reporter: When going into the mainnet, from the perspective of investors holding KAI, what benefits will it bring?
The mainnet will make applications running on Kardia faster and more cost effective. Currently, some applications on KardiaChain running in conjunction with the Ethereum platform incur high fees. And the second advantage, when I have a mainnet, there are many better upgraded products.
Reporter: Recently, KardiaChain has been continuously named on the potential token rankings of major overseas communities. So why do you think KardiaChain is so loved by the international community?
Since its listing, the price of the KAI token has risen to a peak of 2000% and is well received by the international community. I think KAI has some values ​​that Westerners like. There are people who first learned about KAI were quite surprised because KAI has been quietly developing products since 2018 and they understand Kardiachain is a serious project. The second point is that the Kardiachain team has a culture that says it can be done. The announced plans and roadmaps have all been implemented on schedule. And finally, the KardiaChain team did direct marketing, unlike projects that were set up to blow up the price of tokens, they regulate and release news many rounds to push the token price, but doing so is not sustainable, so then the price plummeted again. KardiaChain is not so roundabout that the announcement of the product launch is immediately out. Therefore, this creates confidence in KAI's sustainable development foundation.
Reporter: Thank you Mr. Tri for yourtime. The fourth quarter of 2020 is sure to have many more milestones to look forward to for Kardiachain's supporters. Stay tuned and support Kardiachain!

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.

Dragonchain Foundation

Eth at $500 by the end of the year?

source: ETH price prediction (medium paywall)
Ethereum price prediction 2020 Update 24.10.2020:
Eth at $500 by the end of the year?
Hello everyone, welcome to another update of my Ethereum price prediction 2020, the price of Ethereum (ETH) has recently passed the mark of 400 US dollars in the slipstream of Bitcoin (BTC). The start of Ethereum 2.0 Phase 0 is getting closer.
Although Bitcoin (BTC) recently made the jump above the $ 13,000 mark, Ethereum (ETH) has performed significantly better than Bitcoin this year. While Bitcoin has grown by more than 80% since the beginning of the year, Ethereum investors can look forward to a price increase of around 220%.
Although the daily transactions on the Ethereum Blockchain remain almost at a record level (1.2 million transactions per day), the average transaction costs have recently fallen slightly below the mark of $2.
This is still relatively high compared to the beginning of the year (transaction fees approx. 5 cents), but way better than in September. About 1 month ago, Ethereum users had to pay an average of over $10 for a transaction due to the Defi boom.
Many crypto experts pointed out the hype surrounding decentralized financial services (Defi) as the cause of the drastic increase in transaction fees.
Decentralized applications such as Uniswap (UNI), Compound (COMP), YearnFinance (YFI), CurveFinance (CRV), and Balancer (BAL) faced tough competition to accommodate transactions in blocks so that these transactions are processed relatively quickly — the result is that the network fees are exploding.
The utilization of the Ethereum Blockchain is still over 97%, with Uniswap still using the largest capacities. Nevertheless, the trading volume on Uniswap (UNI) has temporarily fallen below $200 million a day in the last few weeks, after almost $1 billion a day at the beginning of September. This should have contributed to at least a partial relief of the network.
The scaling problems are not yet solved. The Ethereum developers hope, however, with Ethereum 2.0 phase 0 and with the help of 2-layer solutions such as rollups, to get the problems under control in the next few months.
Investors reward this with rising prices.
Ethereum price prediction 2020 Summary At the moment, the chances are still good that Eth 2.0 Phase 0 can start in late November or December.
The start of Eth 2.0 does not solve all of Ethereum’s (ETH) scaling problems, but it lays the foundation for further scaling in 2021. From a market-technical point of view, things are now looking very good for Ethereum.
After a brief consolidation above the 50-day line in mid-October, Ethereum (ETH) continued its upward trend. The trend-following indicator MACD indicates further rising prices in the next few days, while the Relative Strength Index (RSI) is slowly but surely moving into the overbought area.
In the short term, Ether can run to $450 in the next few days, then the risk of a correction increases. However, In my opinion, the price of Ethereum could be by the end of the year, at $500 and more may well be possible if the start of Ethereum 2.0 succeeds on time and smoothly.

I think ETH could reach even more by the end of the year, what do you guys think new ATH incoming?

Why Ethereum Mining?

1. High market capitalization, second to bitcoin only
Ethereum is the most dynamic blockchain platform in the world, and Ether is the second largest cryptocurrency in the world by market capitalization. There are around 1,200,000 transactions processed per day on this platform. Numbers explain everything.

2. Dapps on Ethereum outnumbers any other blockchain platform
Not only just a digital currency or commodity, ethereum also keeps its original motivation to be a global computing platform that allows users to deploy smart contract on it. As a kind of smart contract programmed for a specific use, there are about 2 ,000 decentralized applications, or dapps, deployed on ethereum by this June, which is more than the total numbers of dapps deployed on any other general purpose blockchain platform in the world combined.

3. Considerable payback
ETH mining profit basically consists of two parts: the value of the coins and the transaction commission. Once you mined a block, you will not only get the coins, but also the commission to prove the transactions that will be processed in the network. Because of the network congestion brought up by DeFi application ‘s popularity, transaction commission contributes much to the mining profit recently.
(Averages on 17th September,2020:
Ether Price: $389.49
Gas Price: 538 Gwei
Gas Limit:12,472,107
*Commission=538*12472107=6,709,993,566Gwei≈6.71ETH)

Below is a profitability ranking of ASIC miners for some mainstream crypto coins when Gas price is around 60~70Gwei and coin price is about $360. I couldn’t find a ranking that could include all AISIC miners and GPU miners, but it’s enough to show that ETH mining is much more profitable than others. Even though when Gas price and coin price is not very high, the revenue of ETH mining still beats other mainstream cryptocurrencies.

4. Lower Network Difficulty
Compare to bitcoin network hash rate, Ethereum network hash rate is only 244.14TH/s; Less network hash rate means less difficulty, furtherly means that there will be more chance to mine a block and get coins. Nowadays, for bitcoin mining, the possibility to mine a block solo is almost zero, but for ETH mining it is still possible. In my opinion it is the golden time for ETH mining.

Whether you are a new bird or an experienced senior in this field, ETH mining is the best choice in 2020.

Bitcoin book review episode 2 - Decentralized Applications by Siraj Raval What are DApps or Decentralized Applications? An Introduction to Blockchain & Decentralized Apps Decentralized Applications vs Cryptocurrency - Dan Held on the Best Use Case for Blockchain Blockchain Applications  Top 5 Decentralized Applications ...

Decentralized applications don‘t necessarily need to run on top of a blockchain network. Tor, BitTorrent, Popcorn Time, BitMessage, are examples for decentralized applications that run on a P2P network, but not on a blockchain – which is a special kind of P2P network (read more: Origins of Bitcoin and Web3). Basically, decentralized applications allow us to use smart contracts and the blockchain in a user-friendly way. In the example we used earlier about selling a house using a smart contract, the dApp would be what you download onto your phone or use on your PC to actually set a price for your house, input the details and upload photos, etc. Decentralised applications, or DApps, are the foundation upon which currencies like Bitcoin and Ethereum are built. They are open-source, they are decentralised, they have an inbuilt consensus mechanism and they offer some form of incentive to self-sustain. In essence, they dictate the decentralised nature of cryptocurrencies like Bitcoin and are contributing to exciting changes in the digital ... Types of Decentralized Applications (dApps) The decentralized applications use various Blockchain models, depending on the model that is leveraged, these dApps are classified into three categories: Type I: The dApps which have their own blockchain are categorized as Type I dApps. Bitcoin comes under this category along with various other ... Blockchain & Bitcoin. Class intro & fundamentals lecture slides. HW #0 (landscape research) out handout: April 4.
