How does execution of scripts occur in Ethereum? Is it possible to build concurrent 'contracts'?

I find Ethereum quite intriguing, and I'm looking to explore what's possible.
Specifically, I'm curious if a script can be run in multiple 'threads', or if they can only get one thread per script. For example, could one 'contract' spin off multiple 'contracts', and wait for their outputs to be gathered?

Dev help reqd

Hi all is this the place to come if a community is in need of devs to help out on a decentralised blockchain project with a lot of promise but which is lacking in devs to move it onwards? I'm sure it has potential in the defi space too 😁
It's already fully working albeit some bugs which are hampering things like server keeps going down for some reason. It already has many working apps etc, just dev effort has waned and disappeared in the current covid, defi climate. But I'm sure it has potential for use in defi space anyway.
The blockchain is a fork of eth, and allows big data to be sent v cheap over the blockchain, and various use cases open up due to this factor too as well as AI.
We would welcome anyone to look into the github and give their unbiased opinions.
Thanks

Solana: Reddit's 5-Day Scaling Challenge in 5 minutes, 40 seconds. Play break.solana.com to experience it for yourself!

Reddit's 5-day Challenge in 5 minutes on the Solana mainnet. No sharding, no Layer-2!
Hey everyone, I’m Raj Gokal from the Solana Foundation. Solana tackled the Scaling Bake-Off this week and completed the entire 5-day challenge in around 5 minutes for less than $5 USD.
Here are the benchmarks of our challenge:
  • Solana completed token minting in under 2 seconds across 64 threads;
  • Solana completed 204,800 token transfers and point claims in 3 minutes, 20 seconds;
  • Solana burned 75,520 tokens in 46 seconds;
  • All while running on Solana’s mainnet across 130 geographically-distributed validators.
If you’re a geek, you can run this demo for yourself on our mainnet. You can even parallelize it on as many machines as you want and run it on mainnet. But if you just want to see it in action, I put together this video to show the entire challenge start to finish and to share a bit more about Solana.
📺 Watch Solana complete the 5-day challenge in 5 minutes, 42 seconds.

Play the “Break” Game

I invite you to experience the raw speed of Solana for yourself. In addition to the demo, we also built an interactive demo called "Break" to illustrate Solana’s speed real time. It’s simple to play. Just smash keys on your keyboard. Each key sends a real transaction to the Solana mainnet. Every time a block changes color from black to green you know the transaction has been:
  1. Sent from the client to the server
  2. Forwarded from the server to the the block producer
  3. Added to a block and propagated to the network
  4. Voted on by everyone in the network
  5. Approved by 2/3+ of votes, which is detected by the server
  6. Sent back to the client, which gets the notification to turn the box green
Every blockchain claims to be fast, so it’s really hard to tell what’s real. A real-time game is the best demo we could come up with to prove to you how fast Solana really is. We’re also running a competition right now to encourage concurrent usage on the network.
Please make sure to post pictures of your broken keys/keyboards or high scores on solana. We’ll give out 1,000 SOLs to the 5 best pictures.
Hit me up! If you’re short on the SOL required to play, just reply in this thread with your Solana wallet address or with an imgur link to a screenshot with a QR code. Your first game is on us. (Not that it’s expensive to play anyways. See how long it takes you to burn 1 SOL on break).

About the Network

It’s Live on Mainnet: Check out this dashboard built by one of our awesome validators for network stats. So far, the network has grown larger and faster than any other network we’re aware of:
  • 100 days since mainnet
  • 25 million blocks
  • 1.75 BILLION transactions
It’s Cheap, and Fast as Hell: This network was built for speed by people who used to optimize embedded systems and operating systems for a living. Smart contract transactions are so fast and cheap that we use them for consensus votes!
  • $10 for 1 million transactions
  • 400ms block times
  • ~1.5s confirmation times
It Only Gets Faster: We are obsessively focused on horizontally scaling every part of a layer-1 blockchain without sharding. We will never be in a situation where the demand for the network grows so much that we can’t scale to meet it. Validators can always add more cores, more memory, more SSDs, more network bandwidth, on-demand, when the users need it.
It’s Decentralized: The network has seen a 300% growth of its validators since launch: In March, we launched mainnet with an elite group of 40 validators. To date, we’ve increased that group to over 130 validators actively securing the network. An additional 250 validators on testnet will soon be onboarded to mainnet.
It’s Growing: Since launch, we’ve also announced partnerships with Kin (who are moving 3.5m users over from Stellar as we speak), Serum (a non-custodial CLOB derivatives exchange that recently made headlines), Arweave, Terra, Chainlink, Civic, Akash, Fortmatic, Dfuse, Hummingbot, and more.

Scaling Ethereum

As part of helping projects use Solana interoperably with Ethereum, a bunch of people that helped build Solana are also already building super cool wraps and warps to make native Ethereum assets lightning fast using Solana. Two recent examples of this are our friends at Terra and FTX.
Solana is a Layer-1 blockchain and not positioned as a native Ethereum scaling solution per se. However, I believe we’re headed for a fully connected, multi-chain world where assets can and should easily bridge from one chain to another. Ethereum’s ecosystem is one-of-a-kind—our mission for this project is to help scale its value to global communities like Reddit.
I invite you to join our community to learn more. If you have any questions please leave them in the thread below and I’ll do my best to answer them asap. I’ll be answering questions alongside other members of our team and the community.

A global multi-asset cross-chain social and financial operating system: broaden ecosystem, engage community, bring in developers, create decentralized applications and expand users and network via SPOs

The price of (enter your favorite) cryptocurrency seems to be the main topic these days, so let's skip that and talk about Cardano and its future. As you've probably noticed the voting, funding and challenges to create ideas have arrived and things are getting heated.
A wise man wrote: " It can be argued that a large part of the value of a cryptocurrency is derived from its community, the way it uses the currency, and its level of engagement in the currency’s evolution. "
To add to that: without passionate devs (non IOHK and Emurgo), vibrant users and community, DApps and smart contract builders, native multi-assets issuance, interoperability, businesses and projects created by the dc-fund, the "project Cardano" will become irrelevant and fail.
However, in order to make the right decisions (the wisdom of the crowds) we have be informed and the people that you're trying to attract too. So, to answer the fund2 challenge: " How do we encourage developers and entrepreneurs to build businesses and applications on top of Cardano in the next six months?"
Do we have the right info and do the devs that want to build DApps have this info too?
Let's check and compare https://ethereum.org/en/developers/ vs. https://cardano.org/ -> Developers
I challenge anyone on this subreddit to find the following links about Plutus (designed to enable the creation of smart contracts on Cardano):
https://docs.cardano.org/projects/plutus/en/latest/ (found it via google "plutus docs" and not via docs.cardano.org and this is just copy-and-paste from https://prod.playground.plutus.iohkdev.io/tutorial/#intro)
https://hydra.iohk.io/build/3793507/download/1/plutus.pdf (The Plutus Platform: An IOHK technical report , I found the link via Goguen presentation at Shelley summit https://www.youtube.com/watch?v=NjFUYD5FOkE)
https://prod.playground.plutus.iohkdev.io/ (April 2019 info!) and https://prod.playground.plutus.iohkdev.io/tutorial/
Again, let's compare it to https://solidity.readthedocs.io/en/v0.7.1/ and https://ethereum.org/en/developers/ ? There's a (big) difference, right?
Via cardano.org you can only see a "hint of Plutus" here (https://roadmap.cardano.org/en/goguen/ by scrolling deeply to "Goguen Work scope" and here https://testnets.cardano.org/en/plutus/overview/ with a nice welcome that basically says "we're working on it"). Right now, you would think that Marlowe is the way to go with the lack of Plutus walkthoughs, examples, docs, videos, etc.
To attract people (devs, businesses, new users) to Cardano they need to know:
I recommend to watch video on Goguen (see below) because it tells you basically what kind of devs are they looking for, just skip from slide to slide to speed up the process.
"The key elements of Goguen and the high-level deployment plan for the rest of 2020. Goguen represents the next major roll out of functionality for the Cardano ecosystem, bringing multi-asset standards and smart contracts. Shelley is laying the ground work to establish a robust, decentralized network, powered by stake pools and delegation. Targeting Q4 2020, Goguen will start to empower developers and app builders to create further value and utility on Cardano, to drive further adoption. Our bespoke languages Plutus and Marlowe make it easy to create secure smart contracts, without extensive blockchain knowledge. Goguen will enable you to:
Other videos to watch are on Adrestia (also try to find any info about Adrestia on cardano.org if you can), Plutus, Goguen: Tokens, DApps and More, Project Atlas: Navigating blockchains, Project Catalyst: implementing Cardano's Governance model (our Bob Ross with PhD :))
Another docs worth mentioning are https://iohk.io/en/research/library/ sorted by SMARTCONTRACTS and/or PLUTUS.
Finally, to figure out what's coming and what you can do on Cardano:
Other topics on reddit regarding funding ideas:
This is basically a long TL;DR version ;)! It's important to see what others are doing (like Ethereum), what's missing on our side, what community is thinking and how to engage them and how to get more people into our ecosystem.
So, today, if you ask me: "can you easily start building on Cardano today"? The answer is definitely maybe.
Anyway, let me know your comments or your TL;DR version :-)!

This is our submission to the great Reddit Scaling Bake-off 2020.
It’s a StarkEx Rollup (data on-chain).We did it in 1 proof, 300K transactions, 3,000 TPS, 315 gas / transaction on Ethereum mainnet.
To watch our demo and read our detailed explanation of how we did it - see our post:

Dear Reddit,

This is our submission to The Great Reddit Scaling Bake-off. It’s a StarkEx Rollup (data on-chain).

System Overview


https://preview.redd.it/ut4vmvqy3yd51.png?width=1089&format=png&auto=webp&s=ad7b4402e471ded5aa02ed25d6c7f668e4e3a0aa
The StarkEx engine has on-chain and off-chain components. Generally speaking, off-chain is for heavy-duty computation and storage, while on-chain is for the computationally-lean verification , state commitment, and data-availability required for using the escape hatch.
For a more detailed overview read our medium post. Note, however, that this post describes StarkEx in Validium mode (off-chain data), whereas in this bake-off we demonstrated StarkEx in Rollup mode (on-chain data).A note on terminology: Rollups using cryptographic proofs are often called “ZK-Rollups” even when the proofs are not Zero-Knowldge (ZK); we shall use this common term when referring to the general class of proof-based Rollups.

StarkEx Demo for the Reddit Bake-off

Cost Analysis

TL;DR
  • StarkEx can operate with either on-chain data (Rollup mode) or off-chain data (Validium mode).
  • In this bake-off, we operated in Rollup mode. Our total Mainnet on-chain gas cost was 94.47M gas, which translates to an average of 315 gas per Tx. The off-chain costs were a small fraction of this. These are actual measured Mainnet costs, not optimistic estimates.
  • Running the bake-off in Validium mode would have cost 5M gas total, which is under 17 gas per Tx. StarkWare already has a StarkEx system in Validium mode deployed on Mainnet.
  • StarkEx outperforms other Rollup solutions
  • It outperforms existing ZK-Rollups in both on-chain and off-chain costs.
  • It fundamentally out-performs Optimistic Rollups (OR) in on-chain costs. Because cost is dominated by on-chain costs, it has a fundamental cost advantage over OR.
Details
There are two sets of costs in a StarkEx system:
  1. On-chain costs
  • Submitting and verifying proofs
  • (Only In Rollup mode:) publishing data pertaining to state changes
  1. Off-chain costs: running the StarkEx cloud service, and specifically the provers
In Rollup mode, the on-chain portion is the dominating part of the cost. Note that the actual on-chain cost per Tx is much lower in ZK-Rollup solutions than in OR solutions, since the amount of data that needs to be published is much smaller.
In the bake-off, the actual on-chain costs were 94.47M, (average of 315 gas per Tx) and the off-chain costs were negligible in comparison (less than 5% of on-chain cost).
At a gas cost of 70 gwei, this cost us 6.6 ETH, which at an ETH price of $230 cost $1,518 (average on-chain cost of ¢0.5 per bake-off Tx). Naturally, the USD price fluctuates with the price of gas on Ethereum, and the price of ETH.
94.5% of on-chain costs were due to operating in Rollup mode, i.e. for posting the transaction data on-chain (section 1.b above). Had we run the same in Validium mode, the on-chain costs would have been a mere 5M gas (average of under 17 gas per Tx), and would have cost 0.35 ETH, which translates to a total of $80.5 (average of ¢0.02 per bake-off Tx).
On-Chain Gas Consumption Summary:
StarkEx Cost per Batch of 300K Txs Amortized Cost per Tx
Rollup 94.47M gas or ~$1.5K 315 gas or ¢0.5
Validium 5M gas or ~$80 17 gas or ¢0.02

With StarkEx, the verification cost grows only poly-logarithmically with respect to the batch size. This is displayed most clearly in Validium mode, where data is not posted on-chain, and thus on-chain cost scales sub-linearly (logarithmically) with batch size. Consequently, at high scale, the amortized on-chain cost of a single Tx in Validium mode goes to zero with batch size, and the off-chain cost dominates. In terms of off-chain cost, STARKs have a significant advantage over SNARK-based solutions: latest state of the art STARK provers are 20x faster than state of the art SNARK provers and this speedup is based on fundamental cryptographic reasons¹.
In general, the actual cost depends on various factors, including:
  1. As stated above, on the price of gas on Ethereum, and the price of ETH.
  2. System throughput (number of Tx per second): StarkEx achieves efficiency via batching, as verification cost is only logarithmic wrt the batch size. The bigger the batches, the lower the cost per Tx. Generally speaking, higher throughput lends itself to bigger batches, and thus lower average cost per Tx.
  3. Maximal latency allowed between Tx and its submission on-chain: the bigger the allowed latency, the bigger the batches, and the lower the cost per Tx. Larger latency also better enables timing proof submissions for when gas costs are lower.
  4. Data Availability solution: as mentioned above, the current bakeoff was in Rollup mode, where most of the system cost is the on-chain data availability. Running in Validium mode would have reduced the on-chain cost by a factor of 20x.
  5. Number of concurrent competing off-chain proof operators and mechanism of distributing proofs between them: generally speaking, if several proof operators generate proofs in parallel and compete for submitting them, the off-chain costs grow, as those operators all need to be compensated for their on-going cloud costs.
  6. Business relationship/agreement with the proof operators: if Reddit runs the proof operator itself, the off-chain costs are just the out-of-pocket costs of running the service (including prover license/usage fees). If other entity/ies provide the service, the cost could be higher.
  7. Whether the proofs contain just Reddit Txs, or are they bundled together with Txs from other applications: since batching lowers costs, bundling Reddit Txs alongside Txs from other applications into the same proofs can lower the average cost per Tx.
  8. Optimizations based on usage patterns: StarkEx contains various optimisations within each batch (e.g. bundling together different Txs that relate to the same accounts). In some cases, the usage patterns of the application benefit more from these optimisations (e.g. if in many cases, a batch contains many Txs for the same accounts, the average cost will be lower).
The cost quoted above for the bake-off can provide a decent rough cost estimate for a live system (once again, assuming on-chain data availability; otherwise they would be considerably lower). More exact estimates could be provided once we get tighter specifications for the desired system configuration.
Note that the costs quoted above are the actual variable costs for running the bake-off on Mainnet. We have read various publications from competing scaling solutions quoting costs that are merely estimates, and often neglect significant parts of the actual cost structure, as typically they don’t yet have a fully functional product. As far as we know, STARK (as a cryptographic protocol) and StarkEx (our specific implementation for this use case) are significantly more efficient than other cryptographic proof systems. For example, ethSTARK, our EF-funded open-source code, is 20X faster than any other proof system we know of. This efficiency translates to a cost advantage over other alternatives, when all considerations are taken into account.

System Architecture

Highlights
  • Scalability: High throughput enabled by batching transactions.
  • Integrity: Cryptographic proofs and commitments ensure true ownership of Points.
  • Accessibility: Support by leading wallets, and no on-chain operations required from users.
System Components

https://preview.redd.it/v399tflc4yd51.png?width=700&format=png&auto=webp&s=7385cb25bc135bb0b2183358a1d2cee9d0c62480
Minting (1)
Minting is done by transferring Points from the moderator accounts to chosen users (per Reddit’s specification, users claim these Points). This is done via the Moderator API.
UX — Subscribe, Tip, and Burn (2)
Initiating User Commands
StarkWare built a Reddit Chrome Extension (RCE) that monitors user activity on the Reddit website. The RCE catches events such as Subscribe (clicking the subreddit “JOIN” button), and Tip (adding a response starting with “/tip”), and interprets them appropriately. Whenever the RCE catches a user command, it constructs the required StarkEx transaction, and requests the user to sign it with their selected wallet. The signed transactions are passed by the RCE to the StarkEx Scalability Engine (SESE) in the cloud. StarkEx batches transactions, generates a STARK proof attesting to their integrity, and writes to Ethereum the proof, a commitment to the updated user balances data structure, and the modified user balances.
Frictionless User Experience
Users limiting themselves to the basic Reddit Point interactions (namely: claiming Points, subscribing to a subreddit, tipping other users, and burning Points) need not interact with Ethereum, and in particular, no on-chain registration is required. Only when users choose to interact with Ethereum, e.g. to withdraw or deposit Points, do they need to register on-chain as well. On-chain registration simply means linking a user’s Ethereum address with their StarkEx account.
Wallet Support (3)
Native Integration
Several wallets support the StarkEx ECDSA signature scheme and APIs, offering maximal security to their users. These wallets securely present to the user StarkEx transactions in a clear and readable format, so the user knows what they are signing. This ensures that any attempts at tampering with the message (e.g. by malware) can be detected by the user prior to signing.
Currently provided by: Ledger, Authereum, Portis, and Argent (via WalletConnect).
Standard Integration
Where Native Integration with StarkEx has yet to be completed, we opted for Standard Integration. For the Reddit bake-off, these wallets are used strictly for the secure storage of the user’s private key. When using such a wallet, the RCE itself signs the message with the key it obtains from the wallet.
Currently provided by: MetaMask and Torus.
StarkEx Scalability Engine (4)
The SESE runs in the cloud, and is responsible for batching transactions, generating a STARK proof attesting to their integrity, and updating a commitment (a hash) to the new state of accounts following this batch. StarkEx sends to Ethereum the STARK proof, alongside the commitment. The StarkEx smart contract system checks the proof, and if it is accepted, it stores the commitment on-chain. StarkEx accompanies each proof sent to Ethereum with the list of modified account balances verified by the proof as well (aka on-chain data availability), thus ensuring the anti-censorship mechanism described below.
StarkEx Batch Explorer (5)
The StarkEx batch explorer connects to the SESE. It allows viewing the batches created, and the transactions in each batch. The batch explorer also displays a readable format of the modified accounts data that StarkEx puts on-chain, which the explorer reads directly from the blockchain. Note that the set of transactions displayed requires trust in the explorer, as it cannot be derived merely from observing the commitment and the modified accounts recorded on the blockchain.
Anti-Censorship Mechanism
Serving All or No One
In StarkEx, a user should always be able to withdraw their Points to the Ethereum blockchain, as ERC-20 coins. In the standard flow, a user sends a withdrawal request to the SESE via an off-chain API. Off-chain API service requires trust in the Operator (e.g. system availability). If a withdrawal request isn’t serviced by the Operator, the user submits a Full Withdrawal request (think of it as the equivalent of filing a complaint to a trustless party) to the StarkEx-Reddit Smart Contract. This triggers a grace period during which the Operator may submit a proof serving the withdrawal request. If that happens, the system reverts to its normal operation. Otherwise, the smart contract freezes the StarkEx system by declining to process any further updates.
Withdrawing Points from a Frozen StarkEx
When the system is frozen, users can claim their Points and withdraw them on-chain , by demonstrating to the smart-contract that they indeed own the claimed assets. The commitment stored on-chain is actually a Merkle tree commitment to the user balances. A user can withdraw funds directly from the contract by providing a Merkle authentication-path from their account (a leaf in the tree) to the root (the commitment kept on-chain). The on-chain data-availability sent with every batch processed contains the information needed to allow a user to construct such authentication paths (the data is broadcast solely for this purpose).

xDai Stable Chain and Splunk: Great Reddit Scaling Bake-Off Submission

xDai Stable Chain and Splunk: Great Reddit Scaling Bake-Off Submission
The xDai Stable Chain is nearing 2 years in production, with exemplary real-world use cases, an active developer community, and full EVM ecosystem compatibility and interoperability with Ethereum. It has been tested at large events (EthDenver) where it handled greater than expected loads with ease; securely processing thousands of transactions for only a few thousandths of a cent. xDai has a proven track record of security and scalability, and it is available for deployment today. While our solution may not be the fastest submitted, it's still well within the requested benchmarks yet brings the peace of mind of dependability and resilience the competition simply cannot offer.

Load testing stats on xDai with Splunk blockchain observability tools

2 projects - 1 mission
The Great Reddit Scaling Bake-Off presented a unique opportunity for collaboration and we were excited to challenge ourselves within such a limited timeframe. Our solution was achieved on the xDai Stable Chain, a layer-2 sidechain which is 100% compatible with Ethereum. Real-time and historical data visualizations with custom dashboards were implemented in collaboration with Splunk. Through this joint effort, we were able to demonstrate a solution that is not only fast but efficient and inexpensive, on a tried and true network that’s in use at this very moment.
Challenge Results
Note: Our challenge Gitbook details our process, results, costs and other details**.**
The challenge asked teams to handle the following transactions over the course of 5 days:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
To meet this challenge, we ported over contracts and created a custom load script to simulate transactions for a single subreddit on xDai. We processed 300,000 transactions in under 4.5 hours, achieving 25X+ efficiency from the original requirements.
Reddit contracts were whitelisted resulting in 0 gas fees for transactions and contract deployment. In addition to the custom load script which tested chain capacity with TMOONs, we also created a continuous load script to simulate more natural transactional flows with TBRICKs.
Load test contract addresses on xDai:
Continuous load test contract addresses on xDai:
To explore scaling for hundreds of millions of users, we set up a modified chain called qDai with 1 second block times, 74M gas per block, and 150+ claim transactions per second. Using this configuration, we completed the load in 29 minutes, a 220X improvement from the requirements.
Contract addresses on qDai:
Please see our challenge gitbook where we organize our results, detail the processes, and address challenge requirements: Gitbook link
Splunk Team Collaborative Effort
The ability to monitor and assess blockchain data is vitally important for accessibility, transparency, and ultimately, adoption. The blockchain team at Splunk created a number of visual dashboards for the challenge to display transactions, block times, validators and all other relevant data on xDai. These dashboards give users the opportunity to find relevant patterns, troubleshoot node issues should they arise, and dig into both historical and real-time data.
The results of our load testing can be viewed using the custom Splunk dashboards created for the competition.
Usability and Interoperability
As mentioned above, the xDai Stable Chain is fully interoperable with the greater Ethereum ecosystem. In this section, we show how users can easily move MOON tokens to and from xDai using a custom plugin (Burner Wallet) connected to the TokenBridge architecture. We also are proud to spotlight community created tools by Austin Griffith, including the xmoon.exchange, and a multiplayer game in active development.
All transactions completed for the challenge are transparent on-chain and can be viewed using our very own xDai BlockScout explorer.

Acknowledgments
We’d like to thank Reddit for the opportunity to show off our technology as a ready-to-go solution for their challenge, and to participate with the Splunk team for a concerted effort in bringing an idea to production. We’d also like to thank any community members who have helped us reach this point and have given us valuable feedback throughout the process.

What is a blockchain bridge and examples of its using

What is a blockchain bridge and examples of its using
Depending on the specifics of the project, it can be built on a blockchain that would best match it. In this case, can happen situations in which chosen blockchain platform does not meet the requirements and has certain disadvantages. And at the same time, no adequate alternative can be found. How to deal with this situation? The conclusion is simple - you need to use a bridge, which serves as a kind of connection, which will allow the project to take advantage of both blockchains.
EXBASE.IO
How does blockchain bridges work?
It works on the principle of the mint-and-burn protocol. It works as follows - during creation of a new token on one of the blockchains, a similar token can be blocked or burned on another, and the process can work in the opposite order. Moreover, with high-quality integration, ordinary data with smart contracts can be transferred along with tokens.
More specifically, the project is planned to be built on the basis of ETH, but at the stage of sending transactions, difficulties may arise - when the network is overloaded, the price for an additional payment for conducting a transaction out of turn is very high. It is impossible to completely abandon this blockchain, since the ETH has a huge community, and the principle of building smart contracts is extremely effective. To do this, we are building a bridge between the ETH and EOS blockchains, on which transactions are faster and the commission is lower.
Examples of using
The Wanchain project is one of the first projects that used the bridge principle. Also in early 2019, it's team presented T-Bridge, an innovative framework that provides the ability to transfer digital assets and ordinary data between blockchains.
Syscoin - ETH - is a better-known example of blockchain bridge and as follows from its name, connects the Syscoin network with ETH. The key feature is that ERC - 20 tokens have access to a settlement protocol known as a “zero-confirmation acyclic graph”, which has the advantage of being able to process 50,000 transactions per second or more.
Conclusion. As follows from the above examples, blockchain bridges are a great tool when it comes to concurrent use of different blockchains, and has a huge perspective in the cryptocurrency industry.

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants

Voici LA chronique à découvrir, intitulée: La guerre contre Bitcoin. Idéal pour comprendre certains tenants et aboutissants… Bonne découverte.
La guerre contre Bitcoin
Bitcoin est peut-être le meilleur outil de liberté économique de cette génération, et peut-être depuis plusieurs générations. Malheureusement, Bitcoin a été furieusement étouffé par une guerre civile brutale depuis environ cinq ans maintenant; menée par des ingénieurs sociaux professionnels de certaines des entreprises les plus puissantes de l'espace des médias sociaux. Leur talent dans l'art et la science de la manipulation a permis aux "Bitcoiners" de se battre largement entre eux plutôt que de chercher à créer des modèles commerciaux innovants basés sur les données qui pourraient révolutionner l'économie mondiale via Bitcoin.
À la suite de la guerre civile de Bitcoin, trois versions concurrentes de Bitcoin ont vu le jour (BTC, BCH et Bitcoin SV ), mais il en est de même pour environ 3000 autres projets et jetons de « crypto-monnaie » se faisant passer pour des entreprises légitimes - jusqu'à un "exit scam" presque garantie, le fait de disparaitre du jour au lendemain avec tout l'argent des utilisateurs. Le principal bienfaiteur de la guerre civile Bitcoin a été Ethereum: une machine à états mondiale qui permet un déploiement facile de tokens et de contrats intelligents, mais le protocole Ethereum ne peut pas évoluer, et parmis les milliers de projets lancés, seule une poignée pourrait même être présentée comme avoir les ingrédients nécessaires pour devenir des entreprises légitimes. La plupart des autres sont des stratagèmes de Ponzi ou des émissions d'actions illégales - enrichissant les développeurs et escroquant les investisseurs amateurs.
C'est dans ce contexte que les défenseurs de BTC et de BCH, les porte-parole d'Ethereum et les altcoiners de tous bords s'alignent pour attaquer sans cesse le protocole Bitcoin préservé uniquement par le réseau BSV. Une industrie composée presque entièrement de criminels, de fraudes et d'arnaqueurs s'est unie contre BSV citant (et c'est là l'ironie) une prétendue fraude et arnaque présumée qui est l'existence même de BSV.
Nous devons nous demander pourquoi ?
Quel est le différenciateur clé de BSV?
Pourquoi tous les arnaqueurs se sont-ils unis contre lui?
Je suis fermement convaincu que pour la plupart, la motivation est la peur de la capacité de BSV à absorber l'économie mondiale et tous les autres projets «crypto» qui vont avec. Pour les autres, ou ceux qui ne comprennent pas le pouvoir du Bitcoin, ils sont entraînés dans une guerre culturelle qu'ils ne comprennent pas. Il est essentiel de comprendre les pouvoirs en jeu et leurs implications pour Bitcoin et l'économie mondiale.
Une histoire brève
Bitcoin a été lancé avec un "livre blanc" sur la liste de diffusion de cryptographie en 2008. Le pseudonyme « Satoshi Nakamoto » a déclaré une solution au problème de la double dépense. Or le problème de la double dépense de tous les précédents systèmes de paiement électronique était le seul facteur limitant l'adoption d'une monnaie électronique fonctionnelle. Il était impossible de prouver exactement qui possédait quelles unités d'argent sur leurs registres distribués, de sorte que les systèmes ne pouvaient pas faire confiance, et ces projets mourraient assez vite. Bitcoin a résolu ce problème avec un concept appelé « preuve de travail». Il poste la question: qui a brûlé le plus de puissance de calcul pour résoudre des énigmes arbitraires afin de rendre compte de l'état du registre d'une manière qui coûte de l'argent, de sorte qu'il y ait une incitation économique à tenir un compte honnête des avoirs de chacun. Ce processus est souvent appelé « exploitation minière » car les nœuds honnêtes qui maintiennent l'état du registre sont récompensés pour leur travail avec des Bitcoins toutes les dix minutes - un peu à la même manière d'un mineur d'or qui est récompensé par de l'or en échange de son travail.
Étant donné que Bitcoin n'avait aucune valeur lors de son lancement, il était extrêmement facile à miner et également gratuit d'envoyer des tonnes de transactions. En théorie, il s'agissait d'un vecteur d'attaque par déni de service (DoS). Une attaque DoS ou DDoS se produit lorsque les nœuds sont inondés de plus de données qu'ils ne peuvent en gérer et qu'ils plantent. Sur un jeune réseau Bitcoin, un crash comme celui-ci aurait été considéré comme un échec du réseau, donc un plafond de 1 Mo de données pour chaque dix minutes de temps de transaction a été codé en dur dans le logiciel - semant la première graine de la guerre civile Bitcoin . De 2009 à 2017, cette limite de 1 Mo sur le total des transactions était l'aspect technique le plus controversé du bitcoin.
Pourquoi est-ce important?
Une seule et simple transaction Bitcoin est relativement petite du point de vue des données, donc 1 Mo toutes les dix minutes donne environ trois à sept transactions par seconde avant que le réseau ne devienne trop encombré. Satoshi Nakamoto a plaidé pour un nombre de transactions au niveau de Visa, ainsi que son successeur direct en tant que développeur principal du projet, Gavin Andresen! Certains des premiers Bitcoiners influents comme Mike Hearn et Jeff Garzik ont ​​également plaidé pour plus de données par bloc pour permettre à Bitcoin de se développer pour rester un simple système de paiement électronique. Ils étaient pour des «gros blocs» contrairement au camp des «petits blocs» qui préconisaient une permanence de la limitation de 1 Mo de Bitcoin.
Le camp des "petits blocs" estiment que Bitcoin n'est pas un réseau de paiement, mais plutôt qu'il s'apparente davantage à une banque décentralisée conçue pour stocker des Bitcoins qui ne bougent jamais: une sorte de coffre-fort d'or numérique. Ils voulaient que la limite de taille des blocs de 1 Mo reste permanente sous les auspices de chaque personne exécutant un «nœud bitcoin complet» sans avoir à payer trop d'espace sur le disque dur. Cela signifierait qu'en période de congestion, les frais de transaction deviendraient absurdement élevés, mais cela n'aurait pas d'importance car le bitcoin ne devrait pas être négocié sauf en grosses quantitées de toute façon. L'autre problème est que s'il est bon marché de rejoindre la gouvernance de Bitcoin, alors le réseau est facile à attaquer par sybil, et je dirais que BTC est régi par des sybilles à ce jour.
Le camp des "gros-blocs" estime que tout le monde sur terre devrait être en mesure d'échanger et de faire ses affaires sur Bitcoin.
Les "petits-blocs" pensent que tout le monde devrait être en mesure de gérer soi-même le registre mondial chez soi, mais que seules certaines personnes très riches devraient pouvoir effectuer des transactions.
Après des années de querelles, en 2017, Bitcoin s'est scindé en deux chaînes distinctes, et en 2018, il s'est à nouveau divisé.
Alors quelle est la différence entre ces versions ?
BTC est actuellement la version qui a le prix le plus élevé, avec la plus petite taille de bloc et la plus grande puissance de calcul. Malheureusement, il est régi par des développeurs de logiciels et des sybilles qui contrôlent le consensus grâce à une utilisation intelligente de logiciels malveillants appelés «soft-fork» qui leur permet de saper les règles du Bitcoin. Ils utilisent ce pouvoir pour changer les règles des transactions en mentant aux nœuds et en leur disant de les valider quand même. Toute la culture BTC consiste à acheter du BTC afin de le conserver jusqu'à un moment dans le futur où il sera vendu. Les paiements avec BTC ou les transactions de toute nature sont méprisés.
BCH est un réseau basé sur Bitcoin qui pense que les blocs devraient être à peine légèrement plus grands, mais ils ont également des développeurs en charge des règles, tout comme BTC, et ils pensent que Bitcoin devrait être catégorisé pour être utilisé uniquement pour le commerce de détail, mais rien de plus. Le réseau change de règles tous les six mois. Les transactions non commerciales sont en général méprisées.
BSV est la version restaurée du protocole Bitcoin original avec tous les paramètres ouverts afin que les nœuds honnêtes puissent s'engager dans un consensus conformément au livre blanc de Bitcoin - par preuve de travail ! Le protocole est gravé dans la pierre afin que les développeurs de logiciels ne puissent pas bricoler les règles. Cela permet aux entreprises de planifier des décennies d'utilisation du réseau et d'investir en toute confiance. En tant que seul réseau bitcoin totalement sans autorisation, le commerce de toute nature est encouragé sur BSV. Tout, allant des réseaux sociaux aux expériences de science des données météorologiques ou aux tests de disponibilité du réseau, est encouragé. Paiements de détail, tokenisation, ou tout autre type de contrat intelligent est simple à déployer sans limitations. Bitcoin SV n'a aucun limite sauf l'esprit humain et l'esprit d'entreprise.
Et c'est la racine de la haine envers BSV.
Les "petits-blocs" ont investi toute leur réputation et leurs moyens de subsistance sur la notion que le bitcoin est incapable de s'adapter. Pendant des années, des experts présumés ont convaincu de nombreuses personnes que les limites de taille de bloc de 2 Mo, 8 Mo ou 22 Mo casseraient littéralement Bitcoin. Ils ont furieusement mis en jeux leur réputation sur ces fausses notions. Et ensuite, BSV a eu de nombreux blocs de plus de 100 Mo. En fait, il y en a même eu quelques-uns de plus de 300 Mo! prouvant que les petits-blocs se trompent sur les limites du réseau. Mais cette prise de conscience est une menace pour l'hégémonie du récit de Bitcoin. Depuis 2015, lorsque le Dr Craig Wright est apparu sur les lieux pour expliquer que le bitcoin avait en réalité ZERO limitations, il a créé un tollé massif parmi l'intelligentsia des petits-blocs. Les leaders d'opinion de l'époque étaient payés pour prendre la parole lors de conférences où ils expliquaient à tort que Bitcoin n'était rien d'autre qu'une réserve de valeur rare sans autre utilité. Le Dr Wright parlait de l'échelle illimitée du réseau, de son exhaustivité de Turing et d'autres notions inconcevables (à l'époque) sur Bitcoin. Sa passion et ses connaissances se sont heurtées à des calomnies et des railleries. Ils se sont concentrés sur l'attaque de son personnage au lieu de discuter de Bitcoin!
C'est devenu l'une des principales méthodes d'attaque des petits-blocs. Lorsque de gros-blocs parlent des capacités de Bitcoin, ils sont ridiculisés en tant qu'escrocs et le sujet est toujours dirigé très loin de la discussion technique, car les petits-blocs savent bien qu'ils sortiraient perdants. Ils fouillent les dossiers personnels et cherchent des moyens de faire taire les gens du camp des grands-blocs de Bitcoin de la même manière que les guerriers de la justice sociale s'engagent dans la culture d'annulation contre leurs ennemis politiques.
Qui est le Dr Craig Wright et que fait-il?
Si vous ne le savez pas, Craig Wright est le scientifique en chef d'une société de recherche sur Bitcoin au Royaume-Uni appelée nChain : une société de 150 à 200 informaticiens. Craig dirige l'équipe qui étudie les possibilités de Bitcoin et de ses applications dans le monde. Il est l'un des experts en criminalité numérique les plus reconnus au monde avec les certifications SANS et GIAC ainsi que les titres GSE CISSP, CISA, CISM, CCE, GCFA, GLEG, GREM et GSPA. En outre, il est un polymathe multidisciplinaire de troisième cycle: un doctorat en informatique, économie et théologie et titulaire d'une maîtrise en statistique et en droit commercial international.
En 2015, il a également été exposé par une publication conjointe de WIRED et Gizmodo en tant que Satoshi Nakamoto, le créateur de Bitcoin. Quelques jours après cette révélation, les gens qui le soutenaient ont vu leurs clés d'accès au code révoquées, et de nombreux autres ont été instantanément bannis. Craig a été mis sous enquête par le bureau des impôts australien pour ce qu'il considérait être une erreur de comptabilisation probable de ses bitcoins. Les retombées ont été agressives et rapides, avec une gigantesque armée de petits-blocs, organisée sur Reddit et autres forums, et nouvellement financée par l'argent de la startup pro-petits-blocs appelée «Blockstream». Leur message était clair: Bitcoin doit garder de petits blocs. Le Bitcoin ne peut pas évoluer, et toute personne proche de Craig Wright sera harcelée pour se conformer à une armée de comptes Twitter anonymes et sans visage.
Au cours des années suivantes, Ira Kleiman, frère du défunt Dave Kleiman, a poursuivi Craig Wright pour sa part du prétendu «Partenariat Satoshi Nakamoto», affirmant que Dave était plus impliqué qu'il ne l'était réellement, et l'affaire est en cours actuellement, jusqu'à courant 2021. Ira Kleiman pense que Craig est Satoshi et a investi une fortune incalculable et a obtenu l'argent d'investisseurs extérieurs pour poursuivre sa poursuite. Il est clair que les bailleurs de fonds d'Ira pensent que Craig est également Satoshi.
Les critiques qualifient souvent la révélation publique et le procès public de Wright de ternir énormément sa réputation, mais il convient de noter que les deux sont arrivés à Wright et qu'il ne souhaitait clairement pas être pris dans l'une ou l'autre situation.
Au lieu de cela, Craig est un défenseur passionné de la vision d'un Bitcoin avec de gros blocs, appelant à la professionnalisation, à la légalisation et à l'utilisation mondiales de Bitcoin pour une utilisation à tous les niveaux du commerce. La réponse à la passion de Craig et à ses affirmations a été d'attaquer sa réputation et d'endosser Internet avec le surnom de «Faketoshi». Lorsque de simples brimades ont échoué contre le Dr Wright, des attaques ont été intensifiées pour remettre en question ses divers diplômes, des pétitions aux universités pour enquêter sur lui pour plagiat dans divers travaux, y compris des thèses de doctorat, etc. Wright a même revendiqué des menaces contre la vie des membres de sa famille et il y a plus qu'une petite preuve que, selon Ian Grigg, une des légendes de la cryptographie: «des gens sont morts pour Bitcoin, vraiment, des gens sont morts».
Les attaques en cours
Cela ne peut être assez souligné: la communauté des petits-blocs est construite autour de tactiques d'ingénierie sociale professionnelle. Gregory Maxwell, co-fondateur de la société Blockstream, a été formé à la pratique de l'ingénierie sociale et l'a utilisé de manière si subversive comme un outil de propagande pendant son mandat en tant que modérateur rémunéré de Wikipedia, qu'il a finalement été démis de ses fonctions avec les journaux d'administration citant une litanie d'infractions, notamment:
«Gmaxwell s'est engagé dans la création de faux comptes en masse…» - Alhutch 00:05, 23 janvier 2006 (UTC)
«Menaces, insultes grossières, usurpations d'identité d'un administrateur», -Husnock 03:18, 25 janvier 2006 (UTC)
«Son comportement est scandaleux. Franchement, il est hors de contrôle à ce stade. Son comportement d'intimidation doit cesser.» - FearÉIREANN 19:36, 22 janvier 2006 (UTC)
«Sa liste de contributions est hors de propos. C'est du vandalisme. C'est un comportement auquel je m'attendrais d'un éditeur en furie, ce que, franchement, Gmaxwell est.» - Splashtalk 20h00, 22 janvier 2006 (UTC)
«Prétend être un administrateur, menaçant de bloquer les personnes qui ne sont pas d'accord avec lui, fait régulièrement des attaques personnelles» - SlimVirgin (talk) 12h22, 22 janvier 2006 (UTC)
Il passe beaucoup de temps sur Reddit et d'autres forums à semer la peur sur les dangers des gros blocs, et il a été surpris en train de faire semblant d'être plusieurs comptes à la fois en train d'avoir de très longues discussions techniques sur Reddit destinées à submerger les nouveaux arrivants avec ce qui ressemble à un débat intellectuel.
Qui d'autre est attaqué?
L'autre cible commune de la machine de guerre anti-BSV est Calvin Ayre: le milliardaire à la tête de l'empire du groupe Ayre. Calvin est un entrepreneur canadien et antiguais qui a lancé un incubateur Internet à Vancouver au tout début du boom Internet. Fils d'un éleveur de porcs, Ayre est surtout connu en dehors de l'économie Bitcoin pour la création et la professionnalisation de l'industrie du jeu d'argent sur Internet. Plus particulièrement, sous la marque Bodog, Ayre a aidé à moderniser les lois financières américaines compliquées et obsolètes en poussant les limites dans les marchés gris qui existent où les dollars américains sont utilisés à travers les frontières pour s'engager dans un commerce juridiquement compliqué comme le jeu d'argent. Son travail dans ce domaine lui a valu une petite fortune et un passage sur une liste des «plus recherchés» pour blanchiment d'argent. C'est un point sur lequel les petits-blocs aiment se concentrer, mais ils le sortent complètement de son contexte. Calvin a finalement plaidé coupable à une accusation de délit, mais a été le fer de lance de la modernisation des lois et règlements américains qui existent aujourd'hui sur les marchés complètement ouverts et fonctionnels. Il est respecté pour son travail dans l'industrie du jeu, les médias et la philanthropie. Calvin est certainement le bienvenu aux États-Unis malgré la critique souvent citée et dépassée selon laquelle il est une sorte de hors-la-loi.
Calvin Ayre
Dans l'économie Bitcoin, Ayre est une figure de proue dans la gestion de nœuds Bitcoin honnêtes pendant plusieurs années sous les marques CoinGeek et TAAL, et il est un investisseur dans nChain ainsi que plusieurs startups dans l'espace BSV. Bien qu'il soit probablement le plus gros investisseur, il n'est pas le monolithe que les petits-blocs laisseraient croire aux critiques. Il est important de comprendre que des segments entiers de l'écosystème BSV existent complètement en dehors de son influence.
Twetch, par exemple, est une entreprise indépendante appartenant à l'écosystème BSV, célèbre pour ses attaques contre les médias sociaux centralisés. Ils sont même connus pour se moquer des entreprises qui acceptent l'argent d'Ayre, en plaisantant que Calvin possède tout sauf Twetch. Bien sûr, ce n'est pas vrai. Un autre excellent exemple est l'investisseur / entrepreneur indépendant Jack Liu : ancien dirigeant de Circle et OKEX. Liu possède la marque de hackathons CambrianSV ainsi que des propriétés précieuses dans l'espace BSV telles que RelayX, Streamanity, Output Capital, FloatSV et Dimely.
Les autres acteurs clés sont MatterPool Mining et leur écosystème Mattercloud: une joint-venture entre des acteurs indépendants de l'écosystème BSV, avec des connexions directes aux protocoles BoostPOW et 21e8 et des relations avec des développeurs BSV indépendants.
Bien sûr, il existe également des marques précieuses financées par Ayre. Il s'agit notamment de la propriété partielle via l'investissement dans HandCash, Centi, TonicPow et Unwriter's Planaria Corp.
Une autre mesure importante à prendre en compte est la distribution de la puissance de hachage. Alors qu'à un moment de l'histoire, les entreprises appartenant à Ayre représentent une quantité importante de hachage sur bitcoin, BSV est aujourd'hui en grande partie exploité par des mineurs concurrents de Binance, F2Pool, OKEX et ViaBTC - dont aucun n'est «ami» de BSV ou d'Ayre, mais beaucoup sont ennemis. Ces mineurs soulignent cependant la nature ouverte et sans permission de BSV pour permettre à quiconque de participer.
Ayre est un acteur important, mais en aucun cas un contrôleur de la direction de la blockchain ou des entreprises indépendantes dans l'économie BSV.
Mais pourquoi Craig poursuit-il tout le monde en justice ?
Tout d'abord, et c'est crucial, le procès le plus important de Craig est l'affaire Kleiman. Les autres cas existent uniquement à cause de la diffamation publique du Dr Wright. Le hashtag #CraigWrightIsAFraud circule largement, poussé en grande partie par un mélange de personnages anonymes sur Twitter. Plus particulièrement Magnus Granath AKA «Hodlonaut» a été averti qu'une accusation publique de fraude courait à son encontre. La carrière du Dr Wright est en informatique et en criminalistique numérique, donc le déclarer publiquement une fraude cause un préjudice financier au Dr Wright dans son domaine d'expertise commerciale. Puisque «Hodlnaut» a refusé de cesser, on lui a envoyer une requête pour être vu au tribunal. Cela a causé le célèbre podcasteur de petits-blocs Peter McCormack à mendier d'être poursuivi aussi - en augmentant la rhétorique diffamatoire contre le Dr Wright. À la demande de McCormack, il a lui aussi été attaqué en justice pour être vu au tribunal.
Cette ère de service a engendré la campagne #DelistBSV menée en grande partie par «CZ», le PDG charismatique de Binance Exchange. Divers autres échanges comme Shapeshift et Kraken ont publié des sondages publics demandant s'ils devaient emboîter le pas, et des petits-blocs bien organisés ont voté en masse pour retirer BSV de leurs échanges - citant la toxicité du Dr Wright pour avoir intenté des poursuites en diffamation contre Hodlonaut et McCormack. Finalement, BSV a été retiré de Binance, ShapeShift et Kraken. Il a également été noté publiquement par Coinbase et Gemini qu'ils ne soutiendraient pas du tout cette version de bitcoin à la suite du drame public.
Au fur et à mesure que les choses progressaient, le fondateur de Bitcoin.com, Roger Ver, a également réalisé une vidéo publique déclarant Wright comme arnaqueur. C'était après avoir travaillé sournoisement avec les développeurs Bitcoin ABC pour coder des points de contrôle dans le logiciel ABC de Bitcoin Cash, divisant de manière permanente le réseau Bitcoin pour la deuxième et dernière fois - un acte pour lequel Roger est également poursuivi par d'autres parties privées en Floride. Roger Ver a été averti que des problèmes juridiques similaires se présenteraient à sa porte pour avoir diffamé le Dr Wright, mais les critiques publiques ont persisté jusqu'à ce que Roger soit également entendu devant le tribunal et fournisse la preuve de la fraude de Wright, sous peine de sanctions pour diffamation publique. Son cas est en instance à Antigua-et-Barbuda, où il est récemment devenu citoyen.
Et ensuite il se passe quoi ?
Nous avons établi l'histoire du Bitcoin, de la guerre civile, des attaques publiques contre Wright, Ayre et BSV. Au moment d'écrire ces lignes, nous pouvons revenir sur les attaques contre Thomas Lee, Tim Draper et Jimmy Wales pour avoir eu une proximité avec BSV. Malgré la pression sociale, le rapport Fundstrat de Lee a rendu un examen élogieux du protocole fixe et de l'évolutivité infinie de BSV. Lee et son équipe étaient heureux de prendre la parole lors des événements précédents de CoinGeek, même après le tollé public.
Pour la conférence CoinGeek 2020 à New York, McCormack, Hodlonaut, « Arthur Van Pelt » et d'autres acteurs tels que le Dan Held de Kraken et une cacophonie de trolls anonymes sur Twitter ont mis à profit leur expérience de la culture d'annulation à la bolchevique pour faire pression sur les orateurs Gary Vaynerchuk , et d'autres orateurs prévus afin de les forcer à annuler leur participation à la conférence. Cette attaque sociale contre BSV, Dr. Wright, Ayre et les autres entreprises qui utilisent le réseau BSV pourrait être un cas gigantesque de fraude à la consommation. Ils trompent activement les gens en leur faisant croire que le protocole fixe et l'évolutivité infinie de Bitcoin SV sont en quelque sorte dangereux, alors qu'en fait, le protocole et le réseau sont imperméables à toutes les attaques, à l'exception de leur ingénierie sociale.
Bitcoin SV s'est développé professionnellement avec un portefeuille de brevets de classe mondiale. Il est utilisé par des entreprises indépendantes pour réaliser des profits et il est exploité sur le marché libre par un groupe décentralisé de nœuds honnêtes qui se font concurrence. Le réseau est fixe, sécurisé et en croissance grâce aux investissements de petites entreprises et de gestionnaires de capitaux mondiaux. Les mensonges au contraire sont basés sur une campagne massive de dénigrement perpétrée par les communautés d'autres cryptomonnaie qui craignent l'adoption mondiale de BSV comme outil de commerce et ce que cela signifiera pour eux. L'histoire ne sera pas gentille avec ces manipulateurs et leurs réseaux qui sont financés par les fraudes probables des échanges de crypto-monnaies off-shore, le (très probablement) frauduleux Tether Stablecoin, et l'économie de "pump-and-dump" qui sous-tend 95% du volume de négociation de l'ensemble de l'économie cryptomonnaie actuelle.
C'est une guerre civile. Il y aura toujours des victimes, mais alors que BTC et BCH se concentrent sur les ragots et les affaires illicites, BSV veut que le monde entier soit plus libre, plus souverain et plus capable de coopérer sur le registre mondial de la vérité afin que les entrepreneurs du monde puissent s'engager dans les grandes entreprises ou de simples nano-services sont rendus possibles uniquement par Bitcoin. Bitcoin est un test d'intelligence. Au fil du temps, les personnes intelligentes pourront voir à travers le brouillard de distorsion de la réalité créé pour confondre les innocents et reconnaître cela pour ce que c'est, une attaque coordonnée pour tenter de supprimer une technologie supérieure qui les rendrait obsolètes.

UYT Main-Net pre-launching AMA successfully completed with a blast

7 pm, 29th September 2020 Beijing time the UYT Main-Net pre-launching AMA successfully completed with a blast!
Here is a full record of the AMA:
Host: Hello everyone, it’s a great honor to host the first AMA of UYT network in China. Today, we have invited the person in charge of UYT Dao.
Let’s ask Mr. Woo to introduce himself Woo: Hello, I’m Ben. I’ve met you in the previous global live broadcast. I’m the director of UYT Dao and the founder of IGNISVC. At present, I’m the CEO of the TKNT foundation and have been engaged in the blockchain industry.
Q1. At present, different types of blockchains have emerged, but cross-chain interaction is still suffering a lot. In your opinion, what is the necessity and significance of cross-chain?
Answer: The full name of UYT is to unite all your tokens, which is to integrate all public chains and increase the liquidity of the whole industry. Our purpose is not to create another public chain, but to become a platform for the exchange of value, technology, and resources of all public chains. What we need to solve is that each individual chain can circulate with each other.
The full name of UYT is to unite all your tokens, which is to integrate all public chains and increase the liquidity of the whole industry. Our purpose is not to create another public chain, but to become a platform for the exchange of value, technology, and resources of all public chains. What we need to solve is that each individual chain can circulate with each other.
Q2. The founder of Ethereum, V Shen, once wrote a cross-chain operation report for bank alliance chain R3, which mentioned three cross-chain methods. Which one does UYT belong to? Can you briefly introduce the cross-chain solution of UYT?
Answer: In Vitalik’s cross-chain report, there are three main cross-chain methods. The first is that both parties do not know that they are crossing the chain, or that they cannot “read” each other, such as the centralized exchange. The second way is that one of the links can read other chains, such as side-chain / relay chain. That is, a can read B, and B cannot read a; The third is that both a and B can read each other’s, which can achieve the value and information exchange between a, B, and the platform. UYT belongs to the third kind.
Our new official website will be online soon. Here are a few simple points: first of all, the architecture of UYT includes relay chain, parachain, parathreads, and bridges. In terms of ductility, it has exceeded almost all the public chains currently online.
In the UYT network, there are four kinds of consensus participants, namely collector, fisherman, nominator, and validator. The characteristics of this model are: first, all people can participate without loss. Secondly, as long as anyone makes more contribution to the ecology, he will get more rewards, otherwise, he will receive corresponding punishment.
The underlying layer of UYT is the substrate, which uses the rust programming language. Rust is committed to becoming a programming language that can solve the problems of high concurrency and high-security systems elegantly. This is also a great advantage that we are different from other blockchain projects in technology.
Q3. What are the roles in the UYT network? What are their respective functions?
Answer: After the main network of UYT is online, there will be four roles: collector, fisherman, nominator, and validator, which is totally different from the current system of the test network.
The collector, in short, is responsible for collecting all kinds of information in the parallel chain and packaging the information to the verifier.
Fishermen, to put it bluntly, is fishing law enforcement, which specifically checks out malicious acts and gets rewards after being checked out.
The nominator, in fact, is a group of rights and interests. The verifier is its representative, and they entrust the deposit to the verifier.
Verifier, package new blocks in the network. It must mortgage enough deposits and run a relay chain client on a highly available and high bandwidth machine. It can be understood as a mining pool. It can also be understood as the node in the current UYT DAPP.
Q4. What is the mining mechanism of the UYT network?
The only way to obtain UYT after its issuance is to participate in mining activities. In the initial stage, the daily constant output times of UYT are set to 1440000, and the cycle of bitcoin is halved. Mining rewards can be obtained in the following five ways:
1) Asset pledge mapping mining 2) Become the intermediate chain node of uyt network 3) Recommendation and reward mechanism 4) Voting reward 5) UYT network Dao will take out 10% of gas revenue from block packaging for community construction and reward of excellent community personnel
Q5. The rise and fall of the blockchain are very fast. In order to give investors confidence, is there a detailed development plan, implementation steps, and application direction of UYT network in the next few months?
Answer: UYT Network test network has been running stably for a year. After the main network is launched, all mechanisms will undergo major changes.
The relationship between the UYT test network and the main network can be understood as the relationship between KSM (dot test network) and dot the main network, and the feasibility of the technology can be reflected more quickly by the UYT test network because of its faster timeliness and all future technology updates Some will move to the main network after the stable operation of the test network.
In order to give users a better experience and give more rewards to excellent nodes, all Dao organizers are working hard for it.
The development team has completed the cross-chain of bitcoin and some high-quality Ethereum based tokens in the early stage, and now the code has all been open source. For other mainstream currencies, community members can apply for funds to develop. In order to develop the ecology and make a better technical reserve, we will set up a special ecological development fund when the main network goes online. The transfer bridge is our key funding direction. The maximum application amount of a team is as high as 100000 US dollars. In addition, if other public chains want to connect to UYT, they will get technical support. In order to encourage developers to participate in ecological construction, Dao also launched a series of grants to support development. Developers can directly pull the better applications on Eth and EOS directly, or develop new products according to their own advantages. These directions are now the focus of funding.
Due to the early online testing time of uyt network, it is based on the earlier version of substrate1.0. The on-chain governance mode can only be realized after the upgrade of 2.0 is completed.
At present, the upgrading work is going on steadily, and the on-chain governance will be implemented in the main network with the launch of the uyt main network.
As a heterogeneous cross-chain solution with high scalability and scalability, UYT network can perfectly bridge the parallel encryption system and its encryption assets in theory, and its wide applicability in the future can be expected. Therefore, we do not limit the areas where UYT network will play its advantages and roles. But in the general direction, there will be mainly DEFI and DEX ecological plates. From the industry, it can cover a wide range of fields, not only finance but also games, entertainment, shopping malls, real estate, and so on.
Q6、How can UYT help DEFI?
Answer: UYT network can not only link different public chains but also make parallel chains independent and interlinked. Just like the ACALA project some time ago, it has successfully obtained Pantera capital’s $7 million saft agreement. Although the concept of DEFI is very popular now, all DEFI products are still in the ecology of each public chain, and the cross-chain DEFI ecology has not been developed. UYT is to achieve cross-chain communication, value exchange, and develop truly decentralized financial services and products. For example, cross-chain decentralized flash cash, cross-chain asset support, cross-chain decentralized lending, Oracle machine, and other products. At present, our technical team is also speeding up the construction of infrastructure suitable for the landing of more DEFI products and services and is committed to creating a real cross-chain DEFI ecology, which is only a small step of UYT’s future plan.
Q7、TKNT should be one of the hottest projects in the UYT ecosystem recently. Please give us a brief introduction to the TKNT project and the value of TKNT in the UYT ecosystem. Why can TKNT increase 400 times in 7 days? And what is the cooperative relationship between UTC and TKNT?
Answer: I will answer each project from the technical and resource aspects. Let’s first introduce UTC. UTC is the token of Copernican network and the first project of UYT game entertainment ecology. In the future, it will be responsible for linking. Due to the high-quality public chain in the entertainment industry, because of the limited slots of UYT, each field will seek a high-quality partner and help the partner become the secondary relay chain of UYT. After the main network of UYT goes online, many chains will want to access UYT Greater value circulation, due to the limited external slots of UYT, the cost is also very high. At this time, you can choose to connect to UTC first, and then connect UTC to UYT. With more and more links with UYT, it will gradually evolve into a secondary relay chain of UYT network. UTC’s resources, online and offline, offline payment and offline entity applications, also have a very large community base.
The ecological partners have very good operation experience in the game industry. They will use blockchain technology to change the whole game entertainment industry to make it more transparent and fair. At the same time, there are enough entity consumption scenarios. This is also UYT Because of the reason why the network chose to cooperate with it, the UTC project has been supported by the UYT ecological fund. The support fund includes that after the main network is launched, it will also be the first ecological cooperation project supported by UYT. Because of the online time of the main network of UYT, UTC can’t directly form a chain at present and will give priority to issuing on Ethereum. TKNT is a new concept project TKN.com TKN is the largest online centralized guessing game platform in the world at present. TKNT mixes bet mining and DEFI, so it can carry out fixed mining through platform games, build a system that can realize game participation and in application payment in all Dapps based on ERC20, and combine with various financial services.
The reason why TKNT has created a myth of 400 times in 7 days is that the TkN platform has a buyback plan. As we all know, the online quiz game entertainment platform has an amazing profit. Every quarter, the profit will be used to buyback. The strong profit support has led to the huge increase of token. In the future, all users can use UTC to participate in TkN games. Therefore, the main network of UYT is that Line is also of great significance to TKNT. With the maturity of UYT ecology and technology, TKNT can have a more powerful performance. If TKNT wants to link more public chains, it needs to access UYT network, and realize a bigger vision with cross-chain interaction of UYT. After TKNT was launched on the exchange, the highest price has risen to $14, and now it has dropped to about $2.50. You will see that it will once again set a record high and create greater miracles. You will also see that $3 will be the best buying point for TKNT, because there will be several major moves in TKNT, and the global MLM plan will be launched on October 7 in Korea, China, and other countries There will be many marketing teams in Europe to promote TKNT, including DAPP.com As a shareholder of TkN, TKNT will also make every effort to promote TKNT. Secondly, TKNT will be launched next month on the largest digital currency exchange in South Korea, and Chinese users will see the shadow of TKNT on Binance in November. Of course, the decentralized trading platform of UYT will also be launched in the future.
Q8. What is the significance of the launch of UYT’s main network for the industry and ecology?
Answer: UYT is one of the few cross-chain platform projects in the industry at present.
There are many public chains and coin issuing projects. Why? Because of less work, more money. However, there are very high technical and capital requirements for cross-chain and platform. This barrier is very high, so almost no project side is willing to do this. But once this is done, it will be of great significance to the whole industry of digital currency and blockchain.
Because it will subvert the current situation of the whole currency circle and chain circle acting on their own, and the painting land is king. Let each independent ecosystem achieve a truly decentralized and trust-free cooperative relationship. This huge change will promote the whole industry to develop into a healthy and virtuous circle macro ecosystem.
Q9. The slogan of many project supporters is that UYT should surpass Ethereum. What is the difference in technology between UYT network and Ethereum?
Answer: Thank you so much for supporting UYT. In fact, the correct understanding is that UYT is the next era of Ethereum. First of all, UYT has a different vision from Ethereum.
Before the emergence of UYT, Ethereum, and EOS, no matter how well they developed, belonged to the era of a single chain. The popular metaphor is a LAN. However, UYT can realize the interoperability of each chain and bring the blockchain into the Internet era. Secondly, UYT is far superior to Ethereum in technology. It mainly includes three aspects: shared security, heterogeneous cross-chain, and no fork upgrade.
In the case that Ethereum 2.0 has not been implemented, UYT is the most friendly bottom layer for the DFI projects and other Dapps on Ethereum. Now, the hair chain architecture substrate of UYT is compatible with Ethereum smart contract language solidity, so eth developers can easily migrate their smart contracts to UYT.
Up to now, there is no good solution to the congestion problem of Ethereum, while UYT network not only solves the network congestion problem. What’s more, UYT can easily realize one-click online upgrade, instead of having to redeploy a set of contracts on Ethereum for each version upgraded and then require users to follow them to migrate the original assets from the old contract to the new contract. Developers can quickly and flexibly iterate their own protocols to change their application solutions according to the situation, so as to serve more users and solve more problems. At the same time, they can also repair the loopholes in the contract very quickly. In the case of hacker attacks, they can also solve the hacker stealing money and a series of other problems through parallel chain management. We can find that for Ethereum, UYT not only solves the congestion problem we see in front of us but also provides the most important infrastructure for the future applications such as DFI on Ethereum to truly mature into an open financial application that can serve all people. It also opens the Web 3.0 era of the blockchain industry. In terms of market value, Ethereum currently has a strong ecological construction, with a market value of US $40 billion. UYT will also focus on the development of this aspect after the main network goes online. No matter in terms of market value or ecological construction, I have enough confidence in UYT, after all, we are fully prepared.
Q10. What is the progress of the ecological construction of UYT? What opportunities do current ecological partners see in UYT or what changes may be brought about by UYT ecology?
Answer: After the main network of UYT goes online, there will be a series of ecological construction actions, and more attention will be paid to establishing contact with traditional partners. Cross-chain decentralized flash cash, cross-chain asset support, cross-chain decentralized lending, Oracle machine, and other products will also be the key cooperation direction of UYT.
UYT will give priority to the game and entertainment industry because this industry is most easily subverted by blockchain. As the ecological construction of UYT gets bigger and bigger, the future slots will become more and more expensive. The earlier you join UYT ecology, you will get more support from the ecological fund because the ecological fund is also limited. From the perspective of token value-added, all the project parties will cooperate with the project side in the future, and the project side needs to pledge a certain number of UYT to bid for slots, except for ecological rewards, others need to be purchased from market transactions.
The difference between the pledge here and the pledge we understand is that the UYT of the ecological partner participating in the auction pledge cannot enjoy the computing power for mining.
UYT main network has several opportunities for Eco partners to look forward to, the first point is bitcoin, bitcoin will be later than other assets late, but eventually, all the bubble and value will return to BTC, after the wave of DeFi bubble elimination, the focus will be very much in the bitcoin. UYT ecology can provide a more mature bottom layer for defi. In addition, now Ethereum’s DEFI is that of Ethereum and ERC 20 tokens, and the outbreak point of bitcoin has not yet arrived. Therefore, the DEFI of UYT ecology may be the next opportunity, which is a good opportunity for everyone.
The second opportunity is that after the main network goes online, the future UYT ecological projects will compete to bid for slots. In fact, the original intention of UYT is to realize the interconnection of all chains. The chain outside the UYT ecology also needs to communicate. The third is cross-fi. The BIFI is hatched on Ethereum, and the def on UYT can realize multi-chain operation. For example, TkN games or future UTC game platform users can call bitcoin on the UYT chain. This form only belongs to the decentralized finance in the cross-chain era of UYT, which can be called cross-fi.
Q11. Which exchanges will UYT go online next? What is the online strategy like?
Answer: As the founder of ignisvc and as UYT As the head of the Dao organization, we have always had good cooperative relations with major exchanges all over the world. TKNT will appear in several exchanges one after another. Hitbtc exchange in the United Kingdom, Upbit and Bithumb Exchange in South Korea, Bitfinex exchange in the United States, Binance exchange in China, BKEX exchange, and Kucoin exchange in China are all our partners, and they have been paying close attention to UYT Development, UYT is the public chain with the largest user base and the highest community participation in the cross-chain field, so the future value is immeasurable. If we have to go to the exchange, then we will choose one of the above exchanges to launch. But the vision of UYT is to create a fairer, safer, and transparent circulation in the field of digital currency, and users can master all the assets by themselves, Therefore, in the beginning, there is a simple DEX on the UYT wallet, which is a simple matchmaking transaction and is also an on-chain transaction. After the completion of the UYT DEX, more transactions may occur in the UYT DEX.
However, after the main network of UYT is online, centralized exchanges can directly access the block data synchronization of UYT, and it is not ruled out that some exchanges will directly go online for UYT trading. Such exchanges will not enjoy the support of the ecological support fund of UYT. The network project is a community-led project. Each cooperation plan of the exchange will be carried out in the way shared by the community in the future. Dao organization can only implement it according to the voting results.
Q12. What are the plans for the promotion of ecological development and market by the launch of UYT main network?
Answer: The launch of the main network will be completed around October 15.
On the offline side, due to the epidemic situation, we will jointly organize corresponding market activities with nodes in different countries. At present, there are three large-scale offline meetups that have been identified. We will also start a global roadshow when the epidemic is over.
On the online side, we have opened online Wechat, Kakao, Twitter, Reddit, and telegram communities. We will carry out AMA activities in various countries and promote them all over the world in various ways. Of course, we will launch MLM plans and cooperate with more marketing teams.

Solana's Reddit 5-Day Scaling Challenge in 5 minutes, 40 seconds. Play break.solana.com to experience it for yourself!

Solana's Reddit 5-Day Scaling Challenge in 5 minutes, 40 seconds. Play break.solana.com to experience it for yourself!

Reddit's 5-day Challenge in 5 minutes on the Solana mainnet. No sharding, no Layer-2!
Hey everyone, I’m Raj Gokal from the Solana Foundation. Solana tackled the Scaling Bake-Off this week and completed the entire 5-day challenge in around 5 minutes for less than $5 USD.
Here are the benchmarks of our challenge:
  • Solana completed token minting in under 2 seconds across 64 threads;
  • Solana completed 204,800 token transfers and point claims in 3 minutes, 20 seconds;
  • Solana burned 75,520 tokens in 46 seconds;
  • All while running on Solana’s mainnet across 130 geographically-distributed validators.
If you’re a geek, you can run this demo for yourself on our mainnet. You can even parallelize it on as many machines as you want and run it on mainnet. But if you just want to see it in action, I put together this video to show the entire challenge start to finish and to share a bit more about Solana.
📺 Watch Solana complete the 5-day challenge in 5 minutes, 42 seconds.

Play the “Break” Game

I invite you to experience the raw speed of Solana for yourself. In addition to the demo, we also built an interactive demo called "Break" to illustrate Solana’s speed real time. It’s simple to play. Just smash keys on your keyboard. Each key sends a real transaction to the Solana mainnet. Every time a block changes color from black to green you know the transaction has been:
  1. Sent from the client to the server
  2. Forwarded from the server to the the block producer
  3. Added to a block and propagated to the network
  4. Voted on by everyone in the network
  5. Approved by 2/3+ of votes, which is detected by the server
  6. Sent back to the client, which gets the notification to turn the box green
Every blockchain claims to be fast, so it’s really hard to tell what’s real. A real-time game is the best demo we could come up with to prove to you how fast Solana really is. We’re also running a competition right now to encourage concurrent usage on the network.
Please make sure to post pictures of your broken keys/keyboards or high scores on solana. We’ll give out 1,000 SOLs to the 5 best pictures.
Hit me up! If you’re short on the SOL required to play, just reply in this thread with your Solana wallet address or with an imgur link to a screenshot with a QR code. Your first game is on us. (Not that it’s expensive to play anyways. See how long it takes you to burn 1 SOL on break).

About the Network

It’s Live on Mainnet: Check out this dashboard built by one of our awesome validators for network stats. So far, the network has grown larger and faster than any other network we’re aware of:
  • 100 days since mainnet
  • 25 million blocks
  • 1.75 BILLION transactions
It’s Cheap, and Fast as Hell: This network was built for speed by people who used to optimize embedded systems and operating systems for a living. Smart contract transactions are so fast and cheap that we use them for consensus votes!
  • $10 for 1 million transactions
  • 400ms block times
  • ~1.5s confirmation times
It Only Gets Faster: We are obsessively focused on horizontally scaling every part of a layer-1 blockchain without sharding. We will never be in a situation where the demand for the network grows so much that we can’t scale to meet it. Validators can always add more cores, more memory, more SSDs, more network bandwidth, on-demand, when the users need it.
It’s Decentralized: The network has seen a 300% growth of its validators since launch: In March, we launched mainnet with an elite group of 40 validators. To date, we’ve increased that group to over 130 validators actively securing the network. An additional 250 validators on testnet will soon be onboarded to mainnet.
It’s Growing: Since launch, we’ve also announced partnerships with Kin (who are moving 3.5m users over from Stellar as we speak), Serum (a non-custodial CLOB derivatives exchange that recently made headlines), Arweave, Terra, Chainlink, Civic, Akash, Fortmatic, Dfuse, Hummingbot, and more.

Scaling Ethereum

As part of helping projects use Solana interoperably with Ethereum, a bunch of people that helped build Solana are also already building super cool wraps and warps to make native Ethereum assets lightning fast using Solana. Two recent examples of this are our friends at Terra and FTX.
Solana is a Layer-1 blockchain and not positioned as a native Ethereum scaling solution per se. However, I believe we’re headed for a fully connected, multi-chain world where assets can and should easily bridge from one chain to another. Ethereum’s ecosystem is one-of-a-kind—our mission for this project is to help scale its value to global communities like Reddit.
I invite you to join our community to learn more. If you have any questions please leave them in the thread below and I’ll do my best to answer them asap. I’ll be answering questions alongside other members of our team and the community.

Buggy Code Release Knocks 13% of Ethereum Nodes Offline

A “critical bug” has left 13% of Ethereum nodes useless, highlighting what is a growing chink in the network’s armor: client centralization.
First hinted at in May and June on GitHub, minority clients Parity-Ethereum and OpenEthereum versions 2.7 and later contain an unknown critical bug that stops nodes from syncing with the network’s latest block.
Such bugs would be a normal issue if it weren’t for the length of time it will take to fix (weeks to months) and additional strain it’ll place on the majority client, Geth.
Clients themselves are different programming language implementations of blockchain software. Running multiple implementations together is considered a way to thwart network attacks by having concurrent yet separate systems running.

[RE] 'Half-Blood Prince' Kratos: Could it become an exchange killer?

Read an article about KuCoin's public chain, thought it would be interesting to share it with more devs. I have myself translated the whole text, hope I didn't get anything wrong from the original version.
https://www.ccvalue.cn/article/450999.html Here I put the link to the original article just in case.
I'm relatively new to the chain area, so looking forward if any of you could share some insights with me, whether KuCoin's chain is worth what it says. Or just, what is says aha.
If anyone would like to have more info around KuCoin's public chain I'll be glad to translate more and have it shared here.
Enjoy reading!


------------------------------------------------------------------------
As the DeFi concept overtakes the market, this three-year-old novelty is showing more and more of its power.
Decentralised stable coins, decentralised lending, decentralised derivatives, decentralised exchanges... DeFi has emerged in every area of financial products and has achieved considerable success.
Between June and August of this year, the staking volume for the entire DeFi application rose from $1 billion to $4 billion. Decentralized lending protocol - Compound - which exploded with liquidity mining, briefly overtook MakerDAO as the most popular DeFi application. And exchanges, where cryptocurrencies are most profitable, have recently begun to feel the bite of DeFi.
Three of the top 10 staking applications in the entire DeFi market are in the decentralized exchange category. Among them, Curve Finance staking amount reached $290 million, $250 million for Balancer, and $120 million for Uniswap. It has become a clear trend for decentralised exchanges to attack centralised ones.
Decentralised exchanges increase liquidity in the market through "liquidity mining" strategy. For now, the trend continues. Centralised exchanges have seen the impact of the concept of decentralised exchanges, with many of the biggest players, including Binance, Huobi and OKEx, developing their own public chains in preparation for technological change. Among all the public chains launched by centralized exchanges, KuChain launched by KuCoin deserves the most attention.

【01】Centralization exchange pattern: size coexists
In the first and second sections of this paper, we will first analyze the centralized exchange pattern. In this way, we can get a general idea of how the central exchanges will be impacted and which ones could see themselves be replaced first.
Financial trading has one characteristic: obvious network effect, the top tier exchanges take over most of the traffic.
This is because the big exchanges have powerful credit endorsements. Large numbers of customers not only means good liquidity, but also means that the exchange is lucrative enough to afford a hard-core tech team to keep users' assets safe. In addition, they also provided a relatively safe channel for fiat integration, making it the most robust choice for new entrants. As a result, exchanges, which are already the leading players in the industry, can remain on their “thrones” as long as they don't make mistakes, keep normal operations and follow trends.
However, does this mean that the small exchanges do not have the necessary space of survival? In fact it’s totally the contrary. Encrypted asset exchanges have been competing here in China. Small exchanges have become big ones, such as Binance, MXC and KuCoin. Many people attribute the rise of Binance to the opportunity of “4th of September”. Whereas “4th of September” had nearly nothing to do with Binance user increment compared to TRON’s involvement. The real reason for the rise of Binance can be attributed to the wealth effect of intensive alt-coins issuance during that period, which is the key factor for the rapid rise of a platform.
But can an exchange provide a steady stream of wealth effects for its users? That's a tricky question. When exchanges are small, the wealth effect should be taken as the primary consideration; As exchanges grow bigger, the primary issue for platforms shall gradually become compliance. As a long-term consideration, compliance shall lead the big exchanges to shift the focus of their operations from alt-coins to main-coins. This is true of both Binance and MXC.
In other words, the big exchanges will voluntarily cede some of their "alt-coin" markets as their primary objectives shift, which provides a certain space for small exchanges to survive.
It can be argued that the size of the exchanges determines their positions. Large exchanges act as global exchanges in the digital world, while small exchanges act as regional digital asset exchange systems. The big exchanges serve as global, mature digital assets that provide all-coins liquidity 24/7, where traders believe they are "too big to fail" and projects trust their brand endorsements. Small and medium-sized exchanges can only serve as regional digital asset trading venues, serving the long tail projects that big exchanges cannot cover. Indeed, the small exchanges that survive today are also largely supported by community-based projects behind them.
On the other hand, cryptocurrency exchanges have never been purely exchanges, but rather super-hybrid institutions for primary and secondary market transactions. So the exchanges’ customers are not just traders, but also the projects themselves. When there are more traders in an exchange, there is depth of trading, and high-quality projects are willing to get listed; In turn, a good underlying investment within an exchange attracts more traders, which creates a virtuous circle.
As we mentioned earlier, the financial sector has a strong network effect and the winner takes all. However, due to the special circumstances of the industry, the winners are not eating up all the markets now. Which doesn’t make this part of the market going away. Innovative, grassroots projects that can't afford to pay high fees will still find a place to trade. Thus, they have three options: get listed on a small centralised exchange; Set up a small centralised exchange; Get listed on a decentralized exchange.

【02】Dilemma for small exchanges
Community projects need small exchanges, small exchanges need community projects, they both need and support each other. However, as far as the current market is concerned, whether getting listed on a centralized exchange, or a decentralized exchange or having a small exchange of its own, these are helpless moves for projects.
First of all, what kind of exchange would be willing to accept a little-known project without any listing fees? It must be a traffic-starved exchange. In other words, an exchange that lacks liquidity, users and lucrativity. The project is targeting the trading function they provide, while the trading venue is targeting the users in the project’s hands. For the project, such a place would not only bring him no traffic add-on, but would also burden the community members with the risk that the small exchange would somehow go bankrupt.
Since such a small exchange can not bring traffic, but also will expose to the project’s community another layer of risk where centralized institutions go bankrupt, then why does the project not deploy an exchange of its own? After all, the community has chosen to accept the project's token, and a relationship of trust has been established between the two, it is thus natural for the project to list on its own exchange.
However, to start your own exchange is no easy business. Hundreds of thousands dollars capital must be ready with all the technical development and maintenance, as well as design and operational matters. Projects with large communities and numerous users are even willing to pay millions to set up their own exchange. The cost is huge.
If centralised exchanges are such a hassle, what about listing on decentralised exchanges? Here comes some issues again. First, the trading experience on decentralised exchanges is poor. Since all transaction records of a decentralized exchange are linked up, users will feel the transaction speed is slow due to the validation speed of the blockchain itself. Secondly, most of the decentralized exchanges cannot execute high concurrent real-time trading, the volume and depth of trading is not as high as the centralized exchanges, and liquidity is limited. Last but not least: as Ethereum becomes more congested and gas charges soar, using DeFi becomes more expensive, and centralized exchanges are not cost-effective. At present, true DeFi players generally enter the market with more than 50,000 USDT, and retail trading is mostly unprofitable.
In a nutshell, grassroots community projects that have chosen small exchanges face a few situations: centralized exchanges’ bankruptcy risk; deploying their own exchange with at least hundreds of thousands expenses; listing on a decentralized small exchange, but users have poor trading experience. Neither plan is satisfactory.

【03】Kratos:One-click launch of high performance decentralized exchanges
Kratos perfectly solves the major problems that community projects are facing.
As the testnet of KuChain - KuCoin’s public chain - Kratos has its own token and user community, the distribution of tokens is more communitized, so it can be seen as a separate entity from KuChain. It has for mission to explore the path of "DeFi+CeFi". Rather than public chains of Binance, Huobi and OKEx, Kratos's approach is more experimental and more radically reformist toward centralised exchanges.
Kratos is "playing the real game”.
First of all, Kratos is targeting a user base that has a real need, rather than making generalizations about the DeFi concept. This user base is basically community projects that already possess solid competences in terms of traffic, economy and technology, who do not need to rely on the reputation of any exchange, but only need a trading place to realize financial activities. In the first and second sections of this paper, we have pointed out the rigid demands of these projects. The immediate goal of Kratos is to address these practical demands.
In fact, before Kratos, there were other public chains targeting finance oriented and DeFi oriented. But their founding team lacks experience on large exchanges and understanding of the industry's real need for financial oriented public chains, somehow, they failed in terms of application. The main reason is not that their technical ability is not good, the operation team is not strong, but the original intention focused on solving imaginary problems, so the establishment is wrong.
"If a public chain is useless, then it dies." This is the worldview of the designers of the Kratos project.
Secondly, the mechanism and technical design of Kratos are fully in line with the market demand, rather than blindly increasing TPS, or speculating the concept of “decentralization” like "fake projects".
To solve practical problems and make Kratos a "useful" public chain, the designers of Kratos created a four-layer network system.
Layer 0 is the bottom layer of the public chain based on PoS consensus mechanism, mainly ensuring the normal operation of the whole system and the safety of assets. The layer 1 is the Maas Layer (Machine as a service), which provides multi-functional modules, such as MaaS DEX, Maas DeFi, Maas stable coin, etc. These multi-functional modules are called directly by DEX and other DeFi application developers so that they can quickly build their own applications with a minimum input.
These two layers are the basic layers of the Kratos. For any modifications on the basic layer, Kratos community shall proceed to a series of proposals and voting on chain.
The second layer of the network is where DeFi applications are deployed.
Generally public chains stop abruptly at this level, but Kratos is a practical public chain. Since DEX and other applications have a strong demand for liquidity, Kratos then introduces a third layer on its network: this shareable functionality layer is composed of modules - such as the Liquidity Sharing Protocol (LSP) - that can be called by all layer 2 applications.
Through this four-layer network, the DEX developers’ job becomes easier, and the cost of obtaining liquidity for DEX projects is reduced. To exaggerate, the entire chain makes DEX launch possible within "one-click". For those community projects, they don't have to pay a lot to create their own DEX and share liquidity on Kratos.
Third, as a test chain of KuChain, Kratos abandons ideological stubbornness and achieves a deep combination of "DeFi" and "CeFi" from a practical point of view. As the name suggests, DeFi itself means decentralized finance. But is it necessary to decentralise all aspects of the exchange? Is decentralization a means or an end?
Kratos's development team saw decentralisation as a means to keep exchanges open and transparent, while avoiding the risks of centralised exchanges.
However, for traders, a good exchange should not only be open and transparent, but also ensure good liquidity, and make trades as smooth as possible, and reduce trading delays as much as possible.
How does DEX ensure good liquidity? Although Kratos provides liquidity sharing, it is not enough. In a centralised exchange, the classic approach is to introduce market makers. The more market makers there are, the better the trading experience for users. But in a decentralised exchange, a centralised approach to market making does not work. In a centralised exchange, there are no fees to be paid for placing and withdrawing orders, while there are fees to be paid to the exchange when a transaction is completed, so HFT is viable (frequent placing and withdrawing orders). In a fully decentralised exchange, however, both placing and withdrawing orders take place on-chain and require payment of gas fees. It would be unprofitable for market makers to operate as centralised exchanges.
Before Kratos, some DEXs proposed to put the matching process off-chain, that is, to put the order placing, order withdrawing and trading process into the centralized environment, and only put the transaction records on-chain. That would improve efficiency, but it raises a new question: would it guarantee that the exchanges themselves would not do evil?
This is where KuCoin's L3 data push comes in. As a centralized exchange with several years of operation experience and millions of users, KuCoin has profound experience in liquidity, matching, market making, trading depth, user experience and other aspects. In addition, KuCoin is known for its technological prowess and is the only cryptocurrency exchanges in the world with a level 3 data push service with Coinbase. The technical details, which we've covered in a previous article, are simply to make sure that users and exchanges are receiving trading push-data almost at the same time, so that the exchanges can do no harm. This time, they are also using core technology services in KuChain testnet. By fusing the good technology in CeFi with DeFi, users can get an exchange that releases DEX with one click; The private key is in the user's own hands; Trading experience close to a centralized exchange; Market-maker friendly, easy to provide liquidity.
The changes that Kratos has brought to exchanges are revolutionary. At this stage, Kratos does not have the asset issuance capability, but in the next stage, the project will have the opportunity to implement the asset issuance capability on it. When the time comes, maybe there will be new ways to play.

【04】CLL:Forward Looking to Kratos’ future
Kratos builds a possibility, which has only shown one inkling of it, well let’s imagine the trend. Modern society is a world where jobs are increasingly segmented. Take e-commerce, which is closely related to our lives, as an example. In the past, a store needed to purchase, to store and sell goods by itself. Now, the supply chain has been separated from sales, and the store only needs to be responsible for sales. In the highly developed society of the Internet, how do stores take charge of sales? -- by pulling a WeChat group. This is why e-commerce has transformed into Wechat business in recent years.
Now that the store owner's core business can be simplified from stocking, storing and selling to simply running the WeChat group, the most important task for future project owners may not even be development.
Someday in the future, when projects need to realize a function, they can call modules from the ecosystem of a public chain to build applications based on this chain. When they want to get listed on exchanges, they can call DeFi modules on Kratos to form the corresponding decentralized exchange. I don't know if Kratos will introduce a community governance module, a community square module, or even a communication module in the future, but we can imagine a day when Kratos will develop all these functions. At that point, the projects could even realize community autonomy based on Kratos for its community governance. It's all possible.
At that point, the projects’ main task may become community operations, just as it is today. The interaction between people is the key to the product’s success, and the importance of self-development in the product will be constantly weakened.
While we can now see operations taking up a much larger proportion of blockchain projects than other Internet products, this trend is likely to become more pronounced as the number of customised services increases.
Now Kratos has taken that step. It combines centralised and decentralised exchanges, providing customised exchange products for community use. It will bring a new element, whether to a centralised exchange or a decentralised exchange, a community or a project.

It is a good time to reflect on the departure direction of DeFi

It is a good time to reflect on the departure direction of DeFi

https://preview.redd.it/7qgmezggsnj51.png?width=700&format=png&auto=webp&s=af548c50ffe0568e2c49c6de1f14e298ae8a4ee3
In which direction should DeFi develop in the next step?
The market is changing dramatically. The past few days have been like riding a roller coaster. But after several rounds of fluctuations, the DeFi segment in the stock market is still unabated. However, the hidden worries lurking under the surface are always existing.
Almost all resources in the DeFi ecology are on Ethereum. However, there are problems with the DeFi network built by Ethereum, such as the single system performance brought by the foreseeable homogeneous sharding in the future, high gas fee, low security, and low scalability, etc. These vulnerabilities make the many applications hard to use on the DeFi network, including high-frequency trading and the transaction matching modes (We use the Uniswap asset pool model today.)
The problem with ETH1.0 is that the performance is limited, and all the transactions are mixed without any organization. Although there is composability for the DeFi applications, the network needs to operate both DeFi applications and other transactions or DApps.

Network congestion and skyrocketing gas fees

As we all know, Ethereum relies on the consumption of GAS to run its economic operation. Every step of the chain requires the consumption of GAS. Bitcoin plummeted by almost 50% to $3,800, and ETH fell as much as 65.2% just on March 12 and 13, 2020. The plummet caused a run, the Ethereum miner fees that carried a large number of DeFi and DApps skyrocketed, and the network was also congested. The Ethereum GAS fee increased to 10 times of the usual, and the GAS fee was once as high as 1 ETH to successfully package transactions. After that, because the lending operations of DeFi applications require frequent interaction with contracts, the gas fees on Ethereum have also remained high.

Problems inherited from ERC20 tokens are affecting the DeFi products on Ethereum.

If you use Ethereum’s native token ETH, the operation is simple. As long as the ETH is transferred to the contract of the target DeFi application, the contract operation will be the same as when we use cash to invest in stocks or wealth management products. No other operations are required.
However, the operation of tokens minted using ERC20 contracts is very different from native ETH, regardless of whether the tokens minted by these ERC20 contracts are well-known. Before trading, the ERC20 contract first authorizes the DeFi platform’s contract to transfer a specified number of ERC20 tokens on the account, such as USDT, USDC, or WBTC. After approval, the DeFi contract is called to transfer money. The intuitive understanding is to avoid frequent password input in small transactions, we authorized Paypal to open a password-free payment, so that the payment can be directly deducted during consumption. It sounds convenient, but is it that good?
There is a crucial problem here: if the DeFi contract is malicious during the approval process, this DeFi contract has the right to transfer all the ERC20 tokens on our account to any account. It is similar to that we authorize Paypal to perform a password-free operation of the balance, but if a hacker attacked Paypal successfully, this hacker could transfer all our money to his account. Similar things have happened before.
There is a famous project called Bancor, which used to rely on the type of authorization contract for ERC20 processing. However, there was a bug in the contract that allowed the contract to transfer the tokens in the user’s wallet to any hacker designated address after the user was authorized, which caused a loss of almost 100,000 US dollars.
The loss was not so significant because it occurred in the early stage of DeFi development. If it happens today that the DeFi asset scale on Ethereum already reached hundreds of millions, it would cause severe damage to the entire Ethereum ecosystem and the development of DeFi.

Cold shard and hot shard

DeFi needs composability, convenience, and a stronger capability of anti-run. If the throughput is insufficient, sharding technology can be introduced, which is what ETH2.0 does. However, due to the combinability of DeFi, these applications tend to aggregate into one shard, which is prone to clustering effects. This will result in different shards gathering different contents. This is called hot shards and cold shards, which are analogous to different types of cities such as metropolises as New York and Tokyo, and other places like Kyoto and Alaska. Some places have become Wall Street, while other places may become scenic or living areas. Because of the aggregation of different functions, different shards will have different features.
It is quite unwise to develop algorithms to forcibly redistribute load balancing on shards. This is equivalent to using a simple system to determine the development of a complex system, much like a planned economy. However, we can design different features in advance to make them more capable to display their own features, just as humans transformed and utilized the natural resources based on their understanding of nature, thereby improving efficiency. That means, to set up some shards with different performance and even different consensus algorithms (e.g., the features of PoW and PoS are different).
Maybe there will be a major financial shard, like London, or two other special shards with their own features, like New York City and Chicago. Financial shards require high throughput and high cost. These are called hot shards, which carry large-value transactions, otherwise, the gas fee may be too high. Most people will live in the countryside, which means cold shards here. When you need the hot shard features, you don’t need to live in Manhattan, nor do you need to travel to Manhattan occasionally. Most of the time, you will live well on another shard. When one really needs to run on a DeFi shard, it only takes a few minutes of cross-shard transactions.
But the problem generated from this is that since each shard has its own features, it may cause the shards to be independent. What we need is that shards can be harmonious but keep their differences, that is, cross-sharding DeFi needs to be achieved. Today’s multi-chain heterogeneous technology can contribute to solving this problem. Only by solving these problems can more DeFi applications be stimulated.
In our opinion, a mature DeFi platform must have the following features:
Higher Efficiency: Have faster concurrent processing capabilities, i.e., high TPS.
Lower Gas Fee: Lower gas fee can stimulate the enthusiasm of DeFi users and even catalyze the development of high-frequency trading.
More Secure: There are fewer interactive processes in the contract, at least structurally to avoid the problems ERC20 caused due to the different permissions, which leads to complicated interactions and lengthens the operation chain and increases loopholes.
Easier to Use: Various multi-native tokens can be used to pay gas fees during transactions, and thus no need to use designated tokens to pay gas fees.
Easier Combination: It can support the combination of a wide range of contracts, including the combination of different consensus in the same chain, ledger structure, and other elements, and even cross chains, making DeFi a real “Lego”.

Multi-chain heterogeneous + DeFi, one unhindered currency is helping to reach the perfect

Multi-chain heterogeneity has formed “cities” and “villages”, and DeFi has become the financial center among the cities. Since we use cities for comparison, how can we avoid each city’s independent governance and link up the chains of urban interests to form a greater network? The answer is the same as in real life, that is, the so-called currency everywhere.
Ethereum also provides currency, but this currency is not only inefficient, but also indirectly causes security risks. If you want long-term development, such a design is unreasonable.
In the QuarkChain mainnet, multi-native tokens are our primary function for building the next generation of DeFi. Multi-native tokens have basically the same status as QKC in the QuarkChain system. They can call contracts, perform cross-chain operations, and pay gas fees under certain conditions. Native tokens can achieve all of QKC’s functions, including cross-chain transactions, except participating in QKC governance. Most of the non-native asset inconvenience problems faced by Defi can be solved. In the future contracts, the functions of native tokens will be exactly the same as QKC, with the last barrier to the application of multi-native tokens being removed. This also avoids the problem of reducing the security of the entire DeFi system due to the ERC20 token’s authority issue. Next, we will launch our DEX, and then users will have the true feeling of the unimpeded DeFi platform on QuarkChain. Thus, the last piece of the puzzle of multi-chain heterogeneous + DeFi + multi-native tokens has been fulfilled, which brings cost efficiency, user easiness, and security to a new level.
Ethereum’s performance and contract security restrictions have affected development. After our repeated introduction and numerous testing, the multi-native token function is ready to be officially delivered to the community. Soon, community members can mint their own tokens and use them to transfer funds (including cross-sharding), pay gas fees, directly call smart contracts, etc. In conjunction with the DEX that we will launch in the next step, users can actually experience the convenience and innovation brought by multi-native tokens to the blockchain system.
To verify the validity of this theory, we recently launched the Game of DeFi Campaign. In the last stage of the campaign, we launched a simple DEX application and a game: QSwap — the multi-native token version of Uniswap, and Element Miner — a fun mining trading game. This is the new value that DEX and game-based mining will be able to bring to DApp and DeFi applications based on the verification of multi-native tokens with the game format. Because the gas fee is low enough, every step of the operation will be on the chain to ensure security. Meantime, instead of ETH’s high gas fee, which made users either high-cost and low-efficiency, or low-cost and low-security, the multi-native token proves the real security and convenience.
Our Game of DeFi Campaign has already entered the final stage. There are still millions of QKC reward pools waiting for the users to share. Users can download QPocket wallet to participate in this event.

Phase III: King’s Landing — Dex and Liquidity Mining

In this phase, all the community members can have the experience to use our two new products:

QSwap: Multi-native token version Uniswap

Unlike Uniswap, which can only support ERC20 tokens, QSwap supports multi-native tokens. Thus, no extra pre-authorized approval is required in the process, and any multi-native token can be used to pay gas fee ( not only QKC ). Users will get a better experience and maintain more security by avoiding granting unlimited authorization. Moreover, there will be a much lower gas fee due to sharding technology provided by QuarkChain infrastructure.

Element Miner: Interesting mining and trading DApp game

The player’s goal is to collect 5 elements to join the reward pool. However, since these elements are reinforcing to each other (just like the mining throughputs from different projects are different), using QSwap will be the most efficient approach.
One last question: This DeFi campaign uses test tokens. What if the network uses tokens with real value?

Buggy Code Release Knocks 13% of Ethereum Nodes Offline

A “critical bug” has left 13% of Ethereum nodes useless, highlighting what is a growing chink in the network’s armor: client centralization.
First hinted at in May and June on GitHub, minority clients Parity-Ethereum and OpenEthereum versions 2.7 and later contain an unknown critical bug that stops nodes from syncing with the network’s latest block.
Such bugs would be a normal issue if it weren’t for the length of time it will take to fix (weeks to months) and additional strain it’ll place on the majority client, Geth.
Clients themselves are different programming language implementations of blockchain software. Running multiple implementations together is considered a way to thwart network attacks by having concurrent yet separate systems running.
