Let's discuss some of the issues with Nano

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.

Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly. Similar to TCP/IP, email servers, and http servers. Just like Bitcoin full nodes.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.
Obviously there is still a lot of work to be done in some areas, but overall I think Nano is a good place. For people that aren't Nano fans, what are your biggest concerns?

Idea: A Bitcoin mining pool that donates percentage of revenue to developing Bitcoin infrastructure

There are a lot of initiatives in the Bitcoin space which I feel need more funding, and if I am going to support them, I would rather do so by contributing a certain amount on a regular basis as part of a larger group of people, and have a dedicated team decide on worthy projects to fund, rather than trying to find individual projects myself and put up a bounty when I find one, and hope others will join me.
I see mining pools as the ideal place to pool resources for this type of collective effort. I was wondering if anything like a charitable pool existed, and if not, what others thought about the idea of creating one?
What I would like to see is a pool that takes 3 percent profit for themselves, donates 5 percent to Bitcoin-related projects, and leaves 93 percent for the miner.
Some initiatives I would like to see funded:
This one in particular pissed me off as I upvoted the original submission made in /bitcoin by the scammer, thinking it was a legitimate business:
http://www.reddit.com/Bitcoin/comments/1rre79/fucking_fuck_im_going_to_be_so_pissed_off_if_a/
Here's the scammer's submission:
http://www.reddit.com/Bitcoin/comments/1rpbpn/i_have_convinced_my_uncle_to_move_online_with_his/
I would pay to have a dedicated Bitcoin investigative team that goes after scammers.
Perhaps Darkwallet. Perhaps a version of Bitcoin-QT that uses CoinJoin by default.
There's only one full-time paid developer. It'd be nice if there was more funding of the core devs given so much rests on their work
__
That's all I can think of right now, but I'm certain there are many more areas where there are opportunities to fund projects that would really boost Bitcoin.
Thoughts?

What's going to happen in next Epoch i.e. 210 ?

Many stakers are rushing thinking its going out of their hands. For next epoch the decentralized parameter will be changed from d=1 (means IOHK forming all the blocks) to d=0.9 (means only 10% blocks will be produced by stake pools, 90% still by IOHK), and likewise it keeps reducing until d=0 epoch per epoch.
Now, those you're thinking if rewards earning are sure shot if staked now. These 10% blocks whichever pool will form is all random. Your pool can earn or can't earn , both the scenarios are realistic possibility. Better to not rush through, and be supportive the whole protocol transition. Till now we weren't even earning any rewards and still we were supporting Cardano's mission.
For those who are able to stake, and If you feel your pool don't earn rewards during transition, it doesn't mean you have chosen bad pool. There are tons of variable that works for pool to be chosen for block formation, and majorly its random. Give it a thought on those pools. They are in the game, by paying for their Infra, and spending time keeping it running. You are just not earning rewards, but a stake pool is loosing time, efforts and money waiting to earn any rewards.

So, humble requests. Choose pools wisely. Support community. Decentralization is just starting. Once decentralization started, you will earn rewards forever, its not going to go back. Take things easy, and most important support Individual pool owners. Its only we small operators who can give hope to someone that cardano stake pool operation is in individual hands and not big organisations.

Comparing Nano's Nakamoto Coefficient

Inspired by the discussion on the cc subreddit (which I won't link to), I have some questions.
These Nakamoto coefficients aren't very comparable. Miners can reassign their hashrate at any time. Hashrate also has an ongoing, real expense. Nano votes can't be reassigned if the network is controlled, and there's no out of band "real" cost to acquire or maintain control. Thus, it's extremely misleading to try and compare these.
I would say that indeed hashrate has an ongoing, real expense so indeed, performing a 51% attack on Bitcoin will cost you on a per hour basis. On the other hand, get a 51% majority of Nano and you essentially block the network for eternity from what I understand. Bitcoin would most likely also collapse in value if a 51% attack was successfully performed, because even if it were to go offline for an hour and just a few doublespends were performed, it would undermine the store of value mantra quite strongly.
Some sides notes here are, of course, that getting a 51% majority delegates for Nano is extremely difficult or expensive, as you need to buy up a large percentage of the supply yourself or you need to convince a lot of people to delegate to you, which hopefully only works if you build services that use Nano and therefore, in both cases, you have a vested interest in ensuring the Nano network remains valuable.
On the other hand, Bitcoin miners have made large investments in ASICs which means they are strongly incentivized in the same sense, they want the Bitcoin network to remain valuable. Convincing either enough large Nano holders, or large swathes of Bitcoin hash power, would therefore be difficult.
However, wouldn't it, generally, not be easier to find hash power outside the large miners currently mining than it would be to find Nano to give yourself a majority? I'm thinking that to get a 51% majority in Nano as said earlier you need to buy up enough of the outstanding Nano, or convince holders with a vested interest in the value of the Nano network. For Bitcoin however, I could rent out a chunk of Amazon's computing power and set up my own temporary mining operation to compete with the mining pools currently available. It would still be expensive, but, I am assuming, less so than taking the Nano option (even with current market caps).
Is this a fair comparison? Or am I misrepresenting how easy it would be to get a Nano majority, or misrepresenting how difficult it would be to find alternative hash power to mine Bitcoin?
Edit: Comparing to Bitcoin because it has the most hash power, this goes for all PoW crypto.

Symbol Platform by NEM - Tokenomics

First of all, remember that, you can get 1 XYM for 1 NEM you have.
Tokenomics
The Symbol public chain is a self-sustaining economic ecosystem involving node operators, harvesters, investors, users, and the XYM token. In this way, it’s similar to many decentralized blockchains, but there are important differences that make it easier for anyone to earn rewards. Here are the basics of the system.
XYM Supply and Inflation
XYM has a fixed maximum supply of approximately 9 billion tokens. At public chain release, the supply will consist of about 7.3 billion XYM, allocated to users based on their holdings of XEM on the NEM blockchain. Another 1.7 billion XYM will be created as inflationary rewards over time. The inflation rate is closely mapped to that of bitcoin, extending out over the next 100 years. Similar to mining rewards, Symbol’s rewards will be released to each block creator, but based on a POS+ (Proof of Stake+) system.
Proof of Stake
POS+ lets nodes create blocks based on their XYM stakes, which are holdings. Symbol uses the term harvesting instead of mining. The more tokens held by a node operator, the higher the chances of creating the next block and earning harvesting rewards. POS is a well-known system in the blockchain industry, but Symbol adds some improvements. POS+ calculates a score for each node operator based on the size of their stake AND other factors, such as recent network activity and the stakes that other users may delegate to them (see Delegated Harvesting below.) In this way, POS+ attempts to incentivize usage, competition for low fees, and other desirable behavior. You can read details on how POS+ is calculated in the Symbol whitepaper.
Nodes
Node operators all over the world keep the Symbol protocol robust and decentralized. For keeping the system running, node owners earn rewards from four sources.
Node operators can set up their nodes locally or on cloud services. For details on how to set up a node, refer to the developer documentation.
Block Rewards
Since Symbol’s blocks are confirmed several times per minute, rewards are frequent. Block rewards consist of inflation rewards and transaction fees. The chances of earning a block reward are based mainly on the operator’s XYM stake, as well as other factors like network activity. Both node operators and anyone else with a XYM wallet can earn block rewards.
The higher an account’s XYM balance, the higher the chance of it earning a block reward. Even those who don’t run a node can earn block rewards by delegating their stake to a node.
Delegated Harvesting
XYM owners who don’t operate nodes can also earn block rewards by delegating their stake to a node. Holders who delegate their stake retain full ownership of their coins and never expose their private keys. No funds have ever been lost from delegated harvesting. When delegated harvesters earn a block reward, the node operator who processed it earns 25% and the delegated harvester earns 75%. In this way, a node operator can greatly increase their earned rewards, and all holders can participate in rewards whether or not they run a node.
Transaction Fees
Node operators can set their own minimum fees for which they wish to process transactions. The lower the fees accepted, the more transactions they will be able to process. Generous node operators may even choose to process transactions for free if they wish. This creates competition among node operators.
Node Bonus Program
In order to incentivize stability in the number of nodes and circulating supply after launch, bonus rewards will be paid to node operators who maintain nodes with minimum balances of 1 million, 2 million, or 3 million XYM, with higher bonus rates for each tier. These rewards will draw from a fixed pool of reserves and gradually ramp down over six years.
Total Node Income
To summarize, node operators will earn income from block rewards (inflation + transaction fees) based on their own stakes and a 25% share of delegated stake block rewards. Estimates place these combined node rewards at approximately 5% or 6% for the first year, though this is not guaranteed. Operators can also earn bonuses for maintaining minimum stakes of over 1 million XYM.
Inflation Rate
Symbol’s inflation is mapped to bitcoin’s inflation with one difference. Bitcoin halves its rewards every four years. Symbol also drops its reward rate by half every four years, but instead of a single big drop, these reductions are spaced out to occur every quarter. This gives the same overall inflation as bitcoin, but with a more gradual decline.
Team Reserves
The Symbol Core Team will hold approximately 22% of XYM supply for funding future development, marketing, and partner projects. Historically, Core Team funds have not been used for harvesting and there are no plans to begin, meaning more block rewards available for other harvesters.

Generous node operators may even choose to process transactions for free if they wish. This creates competition among node operators.
Node Bonus Program
In order to incentivize stability in the number of nodes and circulating supply after launch, bonus rewards will be paid to node operators who maintain nodes with minimum balances of 1 million, 2 million, or 3 million XYM, with higher bonus rates for each tier. These rewards will draw from a fixed pool of reserves and gradually ramp down over six years.
Total Node Income
To summarize, node operators will earn income from block rewards (inflation + transaction fees) based on their own stakes and a 25% share of delegated stake block rewards. Estimates place these combined node rewards at approximately 5% or 6% for the first year, though this is not guaranteed. Operators can also earn bonuses for maintaining minimum stakes of over 1 million XYM.
Inflation Rate
Symbol’s inflation is mapped to bitcoin’s inflation with one difference. Bitcoin halves its rewards every four years. Symbol also drops its reward rate by half every four years, but instead of a single big drop, these reductions are spaced out to occur every quarter. This gives the same overall inflation as bitcoin, but with a more gradual decline.
Team Reserves
The Symbol Core Team will hold approximately 22% of XYM supply for funding future development, marketing, and partner projects. Historically, Core Team funds have not been used for harvesting and there are no plans to begin, meaning more block rewards available for other harvesters.

Symbol Platform by NEM - Tokenomics

First of all, remember that, you can get 1 XYM for 1 NEM you have.
Tokenomics
The Symbol public chain is a self-sustaining economic ecosystem involving node operators, harvesters, investors, users, and the XYM token. In this way, it’s similar to many decentralized blockchains, but there are important differences that make it easier for anyone to earn rewards. Here are the basics of the system.
XYM Supply and Inflation
XYM has a fixed maximum supply of approximately 9 billion tokens. At public chain release, the supply will consist of about 7.3 billion XYM, allocated to users based on their holdings of XEM on the NEM blockchain. Another 1.7 billion XYM will be created as inflationary rewards over time. The inflation rate is closely mapped to that of bitcoin, extending out over the next 100 years. Similar to mining rewards, Symbol’s rewards will be released to each block creator, but based on a POS+ (Proof of Stake+) system.
Proof of Stake
POS+ lets nodes create blocks based on their XYM stakes, which are holdings. Symbol uses the term harvesting instead of mining. The more tokens held by a node operator, the higher the chances of creating the next block and earning harvesting rewards. POS is a well-known system in the blockchain industry, but Symbol adds some improvements. POS+ calculates a score for each node operator based on the size of their stake AND other factors, such as recent network activity and the stakes that other users may delegate to them (see Delegated Harvesting below.) In this way, POS+ attempts to incentivize usage, competition for low fees, and other desirable behavior. You can read details on how POS+ is calculated in the Symbol whitepaper.
Nodes
Node operators all over the world keep the Symbol protocol robust and decentralized. For keeping the system running, node owners earn rewards from four sources.
Node operators can set up their nodes locally or on cloud services. For details on how to set up a node, refer to the developer documentation.
Block Rewards
Since Symbol’s blocks are confirmed several times per minute, rewards are frequent. Block rewards consist of inflation rewards and transaction fees. The chances of earning a block reward are based mainly on the operator’s XYM stake, as well as other factors like network activity. Both node operators and anyone else with a XYM wallet can earn block rewards.
The higher an account’s XYM balance, the higher the chance of it earning a block reward. Even those who don’t run a node can earn block rewards by delegating their stake to a node.
Delegated Harvesting
XYM owners who don’t operate nodes can also earn block rewards by delegating their stake to a node. Holders who delegate their stake retain full ownership of their coins and never expose their private keys. No funds have ever been lost from delegated harvesting. When delegated harvesters earn a block reward, the node operator who processed it earns 25% and the delegated harvester earns 75%. In this way, a node operator can greatly increase their earned rewards, and all holders can participate in rewards whether or not they run a node.
Transaction Fees
Node operators can set their own minimum fees for which they wish to process transactions. The lower the fees accepted, the more transactions they will be able to process. Generous node operators may even choose to process transactions for free if they wish. This creates competition among node operators.

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.

Don't blindly follow a narrative, its bad for you and its bad for crypto in general

I mostly lurk around here but I see a pattern repeating over and over again here and in multiple communities so I have to post. I'm just posting this here because I appreciate the fact that this sub is a place of free speech and maybe something productive can come out from this post, while bitcoin is just fucking censorship, memes and moon/lambo posts. If you don't agree, write in the comments why, instead of downvoting. You don't have to upvote either, but when you downvote you are killing the opportunity to have discussion. If you downvote or comment that I'm wrong without providing any counterpoints you are no better than the BTC maxis you despise.
In various communities I see a narrative being used to bring people in and making them follow something without thinking for themselves. In crypto I see this mostly in BTC vs BCH tribalistic arguments:
- BTC community: "Everything that is not BTC is shitcoin." or more recently as stated by adam on twitter, "Everything that is not BTC is a ponzi scheme, even ETH.", "what is ETH supply?", and even that they are doing this for "altruistic" reasons, to "protect" the newcomers. Very convenient for them that they are protecting the newcomers by having them buy their bags
- BCH community: "BTC maxis are dumb", "just increase block size and you will have truly p2p electronic cash", "It is just that simple, there are no trade offs", "if you don't agree with me you are a BTC maxi", "BCH is satoshi's vision for p2p electronic cash"
It is not exclusive to crypto but also politics, and you see this over and over again on twitter and on reddit.
My point is, that narratives are created so people don't have to think, they just choose a narrative that is easy to follow and makes sense for them, and stick with it. And people keep repeating these narratives to bring other people in, maybe by ignorance, because they truly believe it without questioning, or maybe by self interest, because they want to shill you their bags.
Because this is BCH community, and because bitcoin is censored, so I can't post there about the problems in the BTC narrative (some of which are IMO correctly identified by BCH community), I will stick with the narrative I see in the BCH community.
The culprit of this post was firstly this post by user u/scotty321 "The BTC Paradox: “A 1 MB blocksize enables poor people to run their own node!” “Okay, then what?” “Poor people won’t be able to use the network!”". You will see many posts of this kind being made by u/Egon_1 also. Then you have also this comment in that thread by u/fuck_____________1 saying that people that want to run their own nodes are retarded and that there is no reason to want to do that. "Just trust block explorer websites". And the post and comment were highly upvoted. Really? You really think that there is no problem in having just a few nodes on the network? And that the only thing that secures the network are miners?
As stated by user u/co1nsurf3r in that thread:
While I don't think that everybody needs to run a node, a full node does publish blocks it considers valid to other nodes. This does not amount to much if you only consider a single node in the network, but many "honest" full nodes in the network will reduce the probability of a valid block being withheld from the network by a collusion of "hostile" node operators.
But surely this will not get attention here, and will be downvoted by those people that promote the narrative that there is no trade off in increasing the blocksize and the people that don't see it are retarded or are btc maxis.
The only narrative I stick to and have been for many years now is that cryptocurrency takes power from the government and gives power to the individual, so you are not restricted to your economy as you can participate in the global economy. There is also the narrative of banking the bankless, which I hope will come true, but it is not a use case we are seeing right now.
Some people would argue that removing power from gov's is a bad thing, but you can't deny the fact that gov's can't control crypto (at least we would want them not to).
But, if you really want the individuals to remain in control of their money and transact with anyone in the world, the network needs to be very resistant to any kind of attacks. How can you have p2p electronic cash if your network just has a handful couple of nodes and the chinese gov can locate them and just block communication to them? I'm not saying that this is BCH case, I'm just refuting the fact that there is no value in running your own node. If you are relying on block explorers, the gov can just block the communication to the block explorer websites. Then what? Who will you trust to get chain information? The nodes needs to be decentralized so if you take one node down, many more can appear so it is hard to censor and you don't have few points of failure.
Right now BTC is focusing on that use case of being difficult to censor. But with that comes the problem that is very expensive to transact on the network, which breaks the purpose of anyone being able to participate. Obviously I do think that is also a major problem, and lightning network is awful right now and probably still years away of being usable, if it ever will. The best solution is up for debate, but thinking that you just have to increase the blocksize and there is no trade off is just naive or misleading. BCH is doing a good thing in trying to come with a solution that is inclusive and promotes cheap and fast transactions, but also don't forget centralization is a major concern and nothing to just shrug off.
Saying that "a 1 MB blocksize enables poor people to run their own" and that because of that "Poor people won’t be able to use the network" is a misrepresentation designed to promote a narrative. Because 1MB is not to allow "poor" people to run their node, it is to facilitate as many people to run a node to promote decentralization and avoid censorship.
Also an elephant in the room that you will not see being discussed in either BTC or BCH communities is that mining pools are heavily centralized. And I'm not talking about miners being mostly in china, but also that big pools control a lot of hashing power both in BTC and BCH, and that is terrible for the purpose of crypto.
Other projects are trying to solve that. Will they be successful? I don't know, I hope so, because I don't buy into any narrative. There are many challenges and I want to see crypto succeed as a whole. As always guys, DYOR and always question if you are not blindly following a narrative. I'm sure I will be called BTC maxi but maybe some people will find value in this. Don't trust guys that are always posting silly "gocha's" against the other "tribe".
EDIT: User u/ShadowOfHarbringer has pointed me to some threads that this has been discussed in the past and I will just put my take on them here for visibility, as I will be using this thread as a reference in future discussions I engage:
When there was only 2 nodes in the network, adding a third node increased redundancy and resiliency of the network as a whole in a significant way. When there is thousands of nodes in the network, adding yet another node only marginally increase the redundancy and resiliency of the network. So the question then becomes a matter of personal judgement of how much that added redundancy and resiliency is worth. For the absolutist, it is absolutely worth it and everyone on this planet should do their part.
What is the magical number of nodes that makes it counterproductive to add new nodes? Did he do any math? Does BCH achieve this holy grail safe number of nodes? Guess what, nobody knows at what number of nodes is starts to be marginally irrelevant to add new nodes. Even BTC today could still not have enough nodes to be safe. If you can't know for sure that you are safe, it is better to try to be safer than sorry. Thousands of nodes is still not enough, as I said, it is much cheaper to run a full node as it is to mine. If it costs millions in hash power to do a 51% attack on the block generation it means nothing if it costs less than $10k to run more nodes than there are in total in the network and cause havoc and slowing people from using the network. Or using bot farms to DDoS the 1000s of nodes in the network. Not all attacks are monetarily motivated. When you have governments with billions of dollars at their disposal and something that could threat their power they could do anything they could to stop people from using it, and the cheapest it is to do so the better
You should run a full node if you're a big business with e.g. >$100k/month in volume, or if you run a service that requires high fraud resistance and validation certainty for payments sent your way (e.g. an exchange). For most other users of Bitcoin, there's no good reason to run a full node unless you reel like it.
Shouldn't individuals benefit from fraud resistance too? Why just businesses?
Personally, I think it's a good idea to make sure that people can easily run a full node because they feel like it, and that it's desirable to keep full node resource requirements reasonable for an enthusiast/hobbyist whenever possible. This might seem to be at odds with the concept of making a worldwide digital cash system in which all transactions are validated by everybody, but after having done the math and some of the code myself, I believe that we should be able to have our cake and eat it too.
This is recurrent argument, but also no math provided, "just trust me I did the math"
The biggest reason individuals may want to run their own node is to increase their privacy. SPV wallets rely on others (nodes or ElectronX servers) who may learn their addresses.
It is a reason and valid one but not the biggest reason
If you do it for fun and experimental it good. If you do it for extra privacy it's ok. If you do it to help the network don't. You are just slowing down miners and exchanges.
Yes it will slow down the network, but that shows how people just don't get the the trade off they are doing
I will just copy/paste what Satoshi Nakamoto said in his own words. "The current system where every user is a network node is not the intended configuration for large scale. That would be like every Usenet user runs their own NNTP server."
Another "it is all or nothing argument" and quoting satoshi to try and prove their point. Just because every user doesn't need to be also a full node doesn't mean that there aren't serious risks for having few nodes
For this to have any importance in practice, all of the miners, all of the exchanges, all of the explorers and all of the economic nodes should go rogue all at once. Collude to change consensus. If you have a node you can detect this. It doesn't do much, because such a scenario is impossible in practice.
Not true because as I said, you can DDoS the current nodes or run more malicious nodes than that there currently are, because is cheap to do so
Non-mining nodes don't contribute to adding data to the blockchain ledger, but they do play a part in propagating transactions that aren't yet in blocks (the mempool). Bitcoin client implementations can have different validations for transactions they see outside of blocks and transactions they see inside of blocks; this allows for "soft forks" to add new types of transactions without completely breaking older clients (while a transaction is in the mempool, a node receiving a transaction that's a new/unknown type could drop it as not a valid transaction (not propagate it to its peers), but if that same transaction ends up in a block and that node receives the block, they accept the block (and the transaction in it) as valid (and therefore don't get left behind on the blockchain and become a fork). The participation in the mempool is a sort of "herd immunity" protection for the network, and it was a key talking point for the "User Activated Soft Fork" (UASF) around the time the Segregated Witness feature was trying to be added in. If a certain percentage of nodes updated their software to not propagate certain types of transactions (or not communicate with certain types of nodes), then they can control what gets into a block (someone wanting to get that sort of transaction into a block would need to communicate directly to a mining node, or communicate only through nodes that weren't blocking that sort of transaction) if a certain threshold of nodes adheres to those same validation rules. It's less specific than the influence on the blockchain data that mining nodes have, but it's definitely not nothing.
The first reasonable comment in that thread but is deep down there with only 1 upvote
The addition of non-mining nodes does not add to the efficiency of the network, but actually takes away from it because of the latency issue.
That is true and is actually a trade off you are making, sacrificing security to have scalability
The addition of non-mining nodes has little to no effect on security, since you only need to destroy mining ones to take down the network
It is true that if you destroy mining nodes you take down the network from producing new blocks (temporarily), even if you have a lot of non mining nodes. But, it still better than if you take down the mining nodes who are also the only full nodes. If the miners are not the only full nodes, at least you still have full nodes with the blockchain data so new miners can download it and join. If all the miners are also the full nodes and you take them down, where will you get all the past blockchain data to start mining again? Just pray that the miners that were taken down come back online at some point in the future?
The real limiting factor is ISP's: Imagine a situation where one service provider defrauds 4000 different nodes. Did the excessive amount of nodes help at all, when they have all been defrauded by the same service provider? If there are only 30 ISP's in the world, how many nodes do we REALLY need?
You cant defraud if the connection is encrypted. Use TOR for example, it is hard for ISP's to know what you are doing.
Satoshi specifically said in the white paper that after a certain point, number of nodes needed plateaus, meaning after a certain point, adding more nodes is actually counterintuitive, which we also demonstrated. (the latency issue). So, we have adequately demonstrated why running non-mining nodes does not add additional value or security to the network.
Again, what is the number of nodes that makes it counterproductive? Did he do any math?
There's also the matter of economically significant nodes and the role they play in consensus. Sure, nobody cares about your average joe's "full node" where he is "keeping his own ledger to keep the miners honest", as it has no significance to the economy and the miners couldn't give a damn about it. However, if say some major exchanges got together to protest a miner activated fork, they would have some protest power against that fork because many people use their service. Of course, there still needs to be miners running on said "protest fork" to keep the chain running, but miners do follow the money and if they got caught mining a fork that none of the major exchanges were trading, they could be coaxed over to said "protest fork".
In consensus, what matters about nodes is only the number, economical power of the node doesn't mean nothing, the protocol doesn't see the net worth of the individual or organization running that node.
Running a full node that is not mining and not involved is spending or receiving payments is of very little use. It helps to make sure network traffic is broadcast, and is another copy of the blockchain, but that is all (and is probably not needed in a healthy coin with many other nodes)
He gets it right (broadcasting transaction and keeping a copy of the blockchain) but he dismisses the importance of it

BTC - Mining Pools and Future Vulnerabilities

- I've seen charts online breaking down the mining pool ownership percentage of BTC. I also know some pools have committed to cap their hash power and operations so as not to gain 51%. However, is it possible that a 51% attack could already be occurring and we have no idea? How do we know the mining operations aren't in collusion already and have not already been double spending, etc? If fraudulent activity occurs would we actually ever know?
- In order for changes to the Bitcoin protocol to be made, 95% consensus must be achieved, otherwise a hard fork would need to occur? Is this the primary reason why changes to the core protocol are so difficult to make?
- With regards to consensus mechanism, moving aside whether PoW/PoS/Other is the proper solution, since the vast majority of voting belongs to large mining pools why would they ever vote for PoS or another non-mining solution? It seems even if a superior consensus mechanism exists it is highly doubtful BTC would ever deviate without a hard fork?
Thanks!

AMM + Limit Order, Will OneSwap Replace Traditional Exchange?

When a thing is denied, something new starts at a higher level.
The update and iteration of the currency circle takes only a few days.
On August 13, Yam, the token of a popular DeFi project, plummeted by 98%, while YFI, another DeFi cryptocurrency, outran the digital currency Bitcoin Gold by value under capital operation.
According to their familiarity with DeFi, blockchain investors in 2020 can be divided into two categories. The "New" investors are active in DEXs such as UniSwap and Balancer, striving for hundredfold returns on investment amid fake projects, while the "old" investors stick to mainstream cryptocurrencies and advocate value investment in the three major CEXs.
Despite its long history, DEX did not prosper until recently. It has processed transactions of over US$520 million in the past 24 hours, and the trading volume for the past week has exceeded the figure across 2019.
But still, many people are stranger to DEX.
I. Will DEX shuffle the existing trading market?
Upon discovering something new, you can describe it, but never evaluate it superficially.
UniSwap occupies 55% of the entire DEX market. Celebrities in the circle enjoy discussing the changes brought by UniSwap on social media and how it will change the existing trading landscape.
On August 5, Jay, CEO of OKEX Exchange, publicly stated that "UniSwap can hardly replace the current mainstream exchanges." on Weibo.
He also listed two reasons:
  1. With insufficient transaction depth, UniSwap cannot support large transactions;
  2. UniSwap cannot set prices independently, but has to follow the prices set by other exchanges.
He also recognized UniSwap’s AMM model in the post.
Soon this post was criticized by Dovy, the founding partner of Primitive Ventures, to the effect that Jay had quite limited knowledge about DeFi and the reasons he proposed did not hold good.
She also mentioned the advantages of a new generation of DEX represented by UniSwap:
Traditional exchanges determine the price and market value according to a small number of chips in the market. By comparison, AMM relies on the entire LP pool to contribute liquidity, and a small number of chips will not lead to severe fluctuations in the price. The price follows the curve of the static liquidity pool within a time range, rather than the manually controlled order book.
2. Is UniSwap good enough to replace centralized exchanges?
Neither OK or Binance had expected that one day their arch rival was not each other, but the newly emerging decentralized exchanges.
With totally different operating methods and business models, DEX and CEX have their own merits.
CEX comes with evident problems. Ordinary users do not trust its security due to the rampant data cheating. For project developers, CEX requires high fees for token listing and maintenance.
The advantage of CEX lies in its low threshold and mature business model.
Just as Jay said, DEXs represented by UniSwap are still faced with great challenges posed by user habits. For example, UniSwap does not support limit orders or the candlestick chart, and users need to rely on a third-party Ethereum wallet for operation.
The innovative AMM model allows ordinary users and small market makers to get involved and earn market-making fees, reducing costs and improving liquidity.
According to the trading volume at this time, UniSwap may not be able to replace mainstream exchanges, but it is good enough to replace second and third-tier exchanges.
3. Is OneSwap an upgraded version or a copy of UniSwap?
"The success of UniSwap proves the necessity of the DEX that does not require permission and supports AMM in the market. However, UniSwap comes with two shortcomings. One is the lack of support for limit orders, which greatly restricts trading methods and liquidity; The other is the excessive transaction cost and poor transaction efficiency due to the limited processing capacity of Ethereum." - Yang Haipo
Recently, OneSwap, known as the upgraded version of UniSwap, announced that it will hit the market in early September, and has received an investment of US$10 million from CoinEX.
To develop an open-source centralized trading platform like OneSwap, it is easy to replicate the technique. But among so many Swap applications in the market, what advantages does OneSwap have over UniSwap?
1. Limit orders
Neither buyers or sellers of UniSwap can set prices independently; instead, they need to follow the prices set by other exchanges. If they want to buy tokens at a specific price, they have no choice but to wait till tokens at such a price appear in UniSwap, a waste of time.
Continuing the good practices of centralized exchanges, OneSwap supports the traditional order book based on rapid exchange, offering more flexible trading methods and further enhancing the liquidity of digital assets.
2. The candlestick chart and depth map
Without an order book, UniSwap has been criticized for its simple transaction interface which does not even contain the basic candlestick chart. As a result, it cannot satisfy numerous traders’ demand for data analysis.
To benchmark against the centralized exchange in terms of user experience, OneSwap has introduced functions such as the candlestick chart, order ticket, and depth map. Just like centralized exchanges with professional charts, OneSwap provided the price trend, trading volume, depth, and other information of different cryptocurrencies for users to set out informed trading plans.
3. Liquidity mining + transaction mining
UniSwap’s AMM model is believed to be a vital catalyst for its explosive growth. With an additional incentive mechanism of transaction mining besides liquidity mining, OneSwap leaves more core benefits to its users.
OneSwap will charge the Taker a fixed percentage of transaction fees based on the transaction amount, while the Maker does not need to pay. The transaction fees are divided into two parts: 60% for liquidity and 40% for the repurchase and burning of ONES. In transaction mining, both liquidity providers and traders will receive ONES as an economic incentive.
The market is looking forward to a new product that is as user-friendly as CEX and as safe as DEX. Is OneSwap qualified to meet such demands?

Complete Guide to OverdriveNTool

We present the complete guide to overclocking GPUs with OverdriveNTool for your Ethereum Mining Rig! In this special we will write a complete guide to OverdriveNTool, in our opinion the most efficient, fast and immediate software for overclocking GPUs dedicated to mining.
The interface is presented in a very simple and no-frills way, as if to suggest how much the program was created to go directly to the purpose.
We remind you that after installing the drivers (see our guide to build a 6 GPU Ethereum Mining Rig) you will need to go through the Radeon Settings (Radeon Settings), select Game, Global Settings and for each GPU in your mining rig (or mining rig) you will need to make sure that HBCC memory is disabled. Do the same with the Crossfire option, checking that it is also disabled. Reboot the system and verify that all video cards have indeed not enabled HBCC and Crossfire before proceeding.
At the following link the software download and technical specifications: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/
Recall that the GPUs in Atiflash will numerically correspond to the GPUs in ONT and Claymore, without misalignment.
First we open our BIOS previously modified with Bios Polaris or, possibly, a stable Bios Mod downloaded from specialized sites such as Anorak via ONT. However, we can also overclock the original Bios of the GPU. Follow the OverdriveNTool guide carefully when operating at these levels!
Click on New to create a new profile for the selected GPU. At first you will find yourself on the 0 which will correspond to the 0 in Atiflash and Claymore. I repeat once again: identical GPUs can behave differently; for this reason, the most stable final overclocking may vary from card to card. It will be sufficient to load the first profile on each subsequent tab, select New, make the necessary changes and save it with a different name (possibly recognizable, such as GPU1-OC Memory or GPU2-Temp, etc ...).
The stages of the GPU and Ram. On the left we find the stages or clocks of the GPU with relative voltage for each sector. Some users disable the first 6 stages (from P1 to P6) to ensure that once the command for the minion is executed, the GPU immediately goes to the last stage. For those who, like us, restart the RIG once every 2 or 3 days, or even more, it is an unnecessary procedure.
We recommend, at least for the first tests, to leave them activated. Once you have reached the limit of the video card, you can check whether disabling them will bring some improvement in terms of hashing on the screen without the pool being affected. Because in effect our goal is to have a high hash-rate and with a minimum percentage of errors on the pool even at the expense of a lower hash-rate in our RIG.
In the central part we find the speed of the memory divided into 3 sectors. We will operate directly on the latter.
On the right you can see the speed of the fans, the temperature that the fans must maintain (in our bios-mode it is set at 75 ° to which we obviously never arrived), the acoustic limit (in a RIG it is a parameter to always keep consideration).
The last section at the bottom right, the Power, is divided into the maximum reachable temperature (with our Pulse set at 84 ° while with the XFX at 75 °) and the Power Target, strictly linked to the modified Bios that we are overclocking . You can try at the end of all tests, in the event of instability of one or more GPUs, to give less power starting from -25%.
In this guide we will refer to the XFX RX 580 8GB GDDR5, with GPU clock at 1200Mhz and Memory at 2150Mhz. 8 video cards theoretically identical in total.
Let's put into practice what has been written up to now ...
We immediately opted for blocking the stages by operating directly on the latter for both the GPU Clock and the RAM. From these levels it starts to drop with the voltage of both the GPU and the RAM, alternatively always checking hashing, consumption and the stability of the system (usually 5-10 minutes are enough). When the voltage is too low, the GPU will not start undermining.

The goal is to obtain the best performance / consumption ratio, always parameterizing the results obtained on the pool. A very high hashrate or very low consumption can often create numerous errors in the mining phase.


With 8 RX580 8GB video cards we reached a total consumption (thus including all the components of the RIG) of 770 Watts for an average of less than 100 Watts per GPU.

The result was achieved by bringing the GPU clock voltage to 1000 and the RAM to 900. Lower values ​​are theoretically possible but could cause system instability. As mentioned previously, each video card is different from the others and on one of the eight GPUs we were forced to lower the power by 25%.

After these tweaks, we got results on the pool with a hashrate often higher than 240mhs.


We would like to emphasize that GPU overclocking is the absolute operation that will take you the longest time. It can take hours to reach the so-called "sweet spot" of each video card. Our OverdriveNTool guide will surely help you!

But this achievement will give you great satisfaction, we guarantee it.
Below the stable settings for the RX Vega 64 video cards of our 13 GPU Mining Rig of which you can see some videos on our YouTube channel: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

STATERA

STATERA
…a smart contract deflationary token within a portfolio of selective coins/token built on the Ethereum blockchain.
INTRODUCTION
BLOCKCHAIN TECHNOLOGY IS CHANGING, DEFI IS EVOLVING! Blockchain technology is changing the World forever, over the past decade, the introduction of blockchain technology to the world and especially the world finance system has proven how convenient and secured the World's finance system can be. Blockchain has proven its' worth to be an essential tool in the world finance system. Varying from a different mode of transaction to the flexible usage of it.
The Ethereum blockchain has played and still playing a significant role in Blockchain finance evolution. With over a hundred projects out there, each aiming and claiming to solve the problem of financing system in the world, Decentralized Finance DeFi has proven to play an essential role in this regard.
Deflationary Projects arise amidst the flow of developers developing ways of making a project unique and scarce through constant reduction of total supply during a transaction. Over the past few years, many projects attempted this approach, however, they failed to achieve this goal as a result of the unsustainability of the project, or the utter intent of some of the developers to scam people of their money. Nevertheless, previous deflationary cryptocurrency attempts have proven the fact that this method alone will not make a project unique or scarce. Hence, a few projects attempted to apply other interesting features to their deflationary projects, some of which are discussed briefly below.
DEFALTIONARY PROJECTS
Through a constant reduction of total supply as a result of a certain percentage of each token transaction sent to 0x address, a deflationary project aims to reduce its total supply to make it scarce, thus increasing the demand and value of the project.

BOMB
The first project to start this on-chain action was BOMB token. With every transaction on BOMB, 1% of the supply is sent to 0xaddress and lost forever, this is known as BURN. Unfortunately, this didn't work for a long time as anticipated, turns out it takes a project more than just that to make it demanding. In light of this, a few other deflationary projects decided to add extra features to its deflationary attribute.

SHUF
A good example of this is another deflationary project called Shuffle Token (SHUF) burn 1% on every transaction, and randomly send another 1% to any of the top 512 holding addresses, this second feature is known as Heap.

BSOV
The third example of a deflationary project with an extra feature is BitcoinSov (BSoV). This deflationary project also has a 1% burn, but its extra feature is mining. This is the only mineable deflationary project in existence as of today.

RTK
The last example is Ruletka (RTK). Ruletka is an experimental ERC20 token, it was developed in the small town of Alatyr in Russia. When a transaction is made using RTK a number is chosen between 1 and 6. If 6 is chosen, the coins in the transaction will be sent to the 0x address and burned. It was developed based on the legend Russian Roulette life gambling game.
Regardless, deflationary projects are yet to receive the world's attention as most of them struggles to be sustainable.
INDEX FUND
For the past two years, Decentralized Finance or DeFi has been undergoing a series of changes and development. DeFi is aimed at providing solutions to the challenges being faced by traditional financial systems using Etherium blockchain as its primary station.
What is Index Fund?
Investopedia.com described index funds as a type of mutual fund with a portfolio constructed to match or track the components of a financial market index, providing broad market exposure with low operating expenses and low portfolio turnover.
Market Index
A hypothetical portfolio of investment holdings representing a segment of the financial market. The calculation of the index value comes from the prices of the underlying holdings. Investopedia. 2017 was a significant year for crypto, however, was succeeded by the extended bear market. The long bear market made it difficult for investors to select which market they are to invest in. since the rise of the crypto market, it has been experiencing a series of ups and downs, making it difficult, especially for retail investors to select the market they are to invest in. the idea of index market in the blockchain industry is something not usually mentioned, while most investors preferred to long or short on BTC or other Alts.
CRYPTOCURRENCY INDEX FUND
Late 2019 and early 2020, cryptocurrency index funds are becoming an item of discussion and interest in the cryptocurrency investment world. A cryptocurrency index fund prevents an investor from the stress of constant or active management of their crypto fund portfolio.
They help spread risks by diversifying an investment across a broad selection of coins, protected from the crypto market volatility. This means your fund is being handled for you, which of course necessitates a form fee. While fees vary from one index fund manager to the other, the differences in fees don't guarantee the performance of one manager over the other. Among the popular cryptocurrency index funds that are currently available on the market as of 2020 includes:

  1. Coinbase Index Fund
  2. BB Index
  3. Iconomi
  4. CBI Index 7 (CBIX7).
Note: this article does not prescribe an index fund or tokens for readers to invest in, rather make your research before investing.
INDEXED-DEFLATIONARY TOKEN
The idea behind an indexed deflationary token is to keep cutting the circulating supply on a transaction basis, coupled with an investment in diverse selective coins on the Ethereum blockchain market.
Using balancer, the idea is to have a deflationary token inside a pool with other assets for example; USDC, ENJ, LINK, KNC, etc. along with the deflationary token itself, all of which are in one pool. When the token is bought, it will automatically re-balance into other sets in the pool, increasing the trade volume and at the same time burning. A mix of index/portfolio token with a deflationary token.

STA
STATERA [STA]
Statera, in Latin, means Balance. STA is a smart contract deflationary token within a portfolio of selective coins/token built on the Ethereum blockchain. The index portfolio includes four Volatile markets and three Stable markets; ETH, MKR, SNX, LINK, DAI, SUSD, DZAR. Leaving STA with 70% volatility and 30% stability. STA is built on a smart contract, holding all the funds including STA itself.
When STA is purchased with ETH, ETH is spread into the weight in the portfolio and STA purchased gets removed from the index amount. The index suit is not fixed, i.e. the coins in the portfolio can be easily replaced should in case the market demand for a change.
The index also charges a fee. Every time a trade is executed through it (not a purchase of STA this time around, but swapping DAI for ETH for example), 1% stays behind and is shared between the portfolio. With the deflationary attribute of STA, the more trades that occur, the more valuable it becomes. The idea is that a price difference will lead to auto-balancing, which means burning. There you have it, An Index-Deflationary Token.

Round up of Cryptocurrency News #3 Week 20/07 - 26/07

Pssst! Hey you. Scroll down for commentary!
Important/Notable/Highlights:
Special Mentions:
You haven't had enough news? Here is some more:
Speculation:
You made it! :)
First up, SORRY! This has been a late post, I have my reasons don't question them (if you must know I'll be posting in the discord - one time only haha). Secondly, I am sure you can agree with me when I say "Wow!" What an incredible week it has been. Last week I thought it was going to take a couple more weeks for more moving price action when it had only taken a few days which has seen Bitcoin reach and pass the $10,000 region. We have also seen the total Market cap for cryptocurrencies increase from about 280B to over 300B (308B at time of writing) within just a few days. A huge injection of liquidity, about 40B, into the market and just to name a few of the best rises in the top 20 (on Coinmarketcap.com), the price of ETH BTC ADA have given good performances/positive responses (With this I will start adding screenshots at the end of each week for timestamp purposes).
This may be a combination from Binance, Mastercard, Paypal, Grayscale investments, VISA AND the DEFI sector. Let me explain... Last week we read about Binance integrating with the company Swipe (SXP) to issue there own debit card expanding the use and reach of cryptocurrency to 31 countries within Europe. Binance's Q2 scheduled token burn of $60.5 Million, this figure correlates with its exchange, margin and futures trading platforms where approximately 20% of profits get burned to increase the price of BNB token (careful as the price has been steady after the burn).
This week we find out Mastercard's expansion into the Cryptosphere as they expand and integrate with the Wirex team to issue a Mastercard-backed Bitcoin debit card, thus further extending the reach of cryptocurrency availability internationally.
"The cryptocurrency market continues to mature and Mastercard is driving it forward, creating safe and secure experiences for consumers and businesses in today’s digital economy " "...Our work with Wirex and the wider crypto ecosystem is accelerating innovation and empowering consumers with more choice in the way they pay"
Mastercard is also reaching out to other emerging cryptocurrency firms to apply to become principal members [Partners] with Mastercard as they have relaxed their digital assets program and look to expand into the Digital Assets and Blockchain environment.
Paypals expression of interest in cryptocurrency facilitiation may bear fruits as it is said Paypal has partnered up with stablecoin operator Paxos (who is already in partnership with Revolut in the US) to facilitate trading through a cryptocurrency brokerage which will enable other firms to integrate cryptocurrency trading functionalities with them. In my opinion this looks much more promising than the Libra association they pulled out from last October as regulations.
Grayscale Investments clears regulatory hurdle as they have been given the green light for its Bitcoin Cash Trust (BCHG) and Litecoin Trust (LTCN) to be quoted in over-the-counter (OTC) markets by US Financial Industry Regulatory Authority (FINRA).
“The Trusts are open-ended trusts sponsored by Grayscale and are intended to enable exposure to the price movement of the Trusts’ underlying assets through a traditional investment vehicle, avoiding the challenges of buying, storing, and safekeeping digital Bitcoin Cash or Litecoin directly.”
More green lights for Cryptocurrency in the US as regulators allow banks to provide cryptocurrency custody services (which may go further than just custody services). A little bit strange as it seems unnecessary and undermines one of the key factors and uses of cryptocurrency which is to be in complete control of your own finances... On another outlook this may be bullish as it allows US banks to provide banking services directly to lawful cryptocurrency businesses and show support for Bitcoin.
Visa shows support stating they have a roadmap for their further expansion into the Crypto sphere. Already working with Crypto platform Coinbase and Fold they have stated they recognise the role of digital assets in the future of money. To be frank, it appears to be focused on stable coins, cost effectiveness and transaction speeds. However they are expanding their support for crypto assets.
AND MOST IMPORTANTLY, DeFI! Our very own growing section in crypto. Just like the 2017 ICO boom we are seeing exorbitant growth and FOMO into the Decentralised Finance sector (WBTC, Stablecoins, Yield farming, DEXs etc). The amount of active addresses on Ethereum has doubled but with the FOMO on their network have sky rocketed their fees! Large use-cases of stable coins such as USDT ($6B in circulation using ERC-20 standard), DAI, TUSD, and PAX. $114M Wrapped Bitcoin (WBTC) on their network acts as a fluid side chain for Bitcoin and DEX trade volume has touched $1.6B this month. With all this action happening on Ethereum I saw the 24HR volume surpass BTC briefly on Worldcoinindex.com
In other news, Bitcoin has been set as a new precedent in a US federal court in a case against Larry Dean Harmon, the operator of an underground trading platform Helix. Bitcoin has now legally been ruled as a form of money.
“After examination of the relevant statutes, case law, and other sources, the Court concludes that bitcoin is money under the MTA and that Helix, as described in the indictment, was an `unlicensed money transmitting business´ under applicable federal law.”
Quick news in China/Asia as floods threaten miners and the most dominant ASIC Bitcoin mining rig manufacturer Bitmain loses 10,000 Antminers worth millions alledgedly goes missing or "illegally transfered" with ongoing leadership dispute between cofounders.
Last but not least, Cardano (ADA) upgrade Shelley is ready to launch! Hardfork is initiated as final countdown clock is switched on. At time of writing the point of no return has been reached, stress tests done and confirmation Hardfork is coming 29/07 The Shelley Mainnet upgrade is a step toward fast, capable and decentralised crypto that can serve billions of people. With the Shelley Mainnet is ADA staking rewards and pools! Here is a chance for us Gravychainers to set up a small pool of our own. Small percentage of profits going into the development of the community, and you keep the rest!
If you read all of my ramblings thanks heaps! I appreciate it! I have added an extra piece of reading called speculation. Most you can speculate on by just reading the headline some others have more depth to them.
Another post next week for a weekly round up! Where do you think the market is going? What is in your portfolio? Let us know in the Gravychain Discord Channel
See you soon!

P.S.
Dr Seuss collectables on the blockchain HECK YEAH! and Bitcoin enters NASCAR, remember when Doge did this? it was like when Doge was trending on TikTok.
... Oh yeah did I also mention Steve Wozniak is suing Youtube, Google over rampant Bitcoin scams. Wait, what? Sydney based law firm JPB Liberty is suing Google, Facebook and Twitter for up to $300B. Just another day in the Cryptosphere.
