On October 20, Eric Yao, Head of EpiK China, and Leo, Co-Founder & CTO of EpiK, visited Deep Chain Online Salon, and discussed “How EpiK saved the miners eliminated by Filecoin by launching E2P storage model”. ‘?” The following is a transcript of the sharing.
Eric: Hello, everyone, I’m Eric, graduated from School of Information Science, Tsinghua University. My Master’s research was on data storage and big data computing, and I published a number of industry top conference papers.
Since 2013, I have invested in Bitcoin, Ethereum, Ripple, Dogcoin, EOS and other well-known blockchain projects, and have been settling in the chain circle as an early technology-based investor and industry observer with 2 years of blockchain experience. I am also a blockchain community initiator and technology evangelist
Leo: Hi, I’m Leo, I’m the CTO of EpiK. Before I got involved in founding EpiK, I spent 3 to 4 years working on blockchain, public chain, wallets, browsers, decentralized exchanges, task distribution platforms, smart contracts, etc., and I’ve made some great products. EpiK is an answer to the question we’ve been asking for years about how blockchain should be landed, and we hope that EpiK is fortunate enough to be an answer for you as well.
Q & A
Deep Chain Finance:
First of all, let me ask Eric, on October 15, Filecoin’s main website launched, which aroused everyone’s attention, but at the same time, the calls for fork within Filecoin never stopped. The EpiK protocol is one of them. What I want to know is, what kind of project is EpiK Protocol? For what reason did you choose to fork in the first place? What are the differences between the forked project and Filecoin itself?
First of all, let me answer the first question, what kind of project is EpiK Protocol.
With the Fourth Industrial Revolution already upon us, comprehensive intelligence is one of the core goals of this stage, and the key to comprehensive intelligence is how to make machines understand what humans know and learn new knowledge based on what they already know. And the knowledge graph scale is a key step towards full intelligence.
In order to solve the many challenges of building large-scale knowledge graphs, the EpiK Protocol was born. EpiK Protocol is a decentralized, hyper-scale knowledge graph that organizes and incentivizes knowledge through decentralized storage technology, decentralized autonomous organizations, and generalized economic models. Members of the global community will expand the horizons of artificial intelligence into a smarter future by organizing all areas of human knowledge into a knowledge map that will be shared and continuously updated for the eternal knowledge vault of humanity
And then, for what reason was the fork chosen in the first place?
EpiK’s project founders are all senior blockchain industry practitioners and have been closely following the industry development and application scenarios, among which decentralized storage is a very fresh application scenario.
However, in the development process of Filecoin, the team found that due to some design mechanisms and historical reasons, the team found that Filecoin had some deviations from the original intention of the project at that time, such as the overly harsh penalty mechanism triggered by the threat to weaken security, and the emergence of the computing power competition leading to the emergence of computing power monopoly by large miners, thus monopolizing the packaging rights, which can be brushed with computing power by uploading useless data themselves.
The emergence of these problems will cause the data environment on Filecoin to get worse and worse, which will lead to the lack of real value of the data in the chain, high data redundancy, and the difficulty of commercializing the project to land.
After paying attention to the above problems, the project owner proposes to introduce multi-party roles and a decentralized collaboration platform DAO to ensure the high value of the data on the chain through a reasonable economic model and incentive mechanism, and store the high-value data: knowledge graph on the blockchain through decentralized storage, so that the lack of value of the data on the chain and the monopoly of large miners’ computing power can be solved to a large extent.
Finally, what differences exist between the forked project and Filecoin itself?
On the basis of the above-mentioned issues, EpiK’s design is very different from Filecoin, first of all, EpiK is more focused in terms of business model, and it faces a different market and track from the cloud storage market where Filecoin is located because decentralized storage has no advantage over professional centralized cloud storage in terms of storage cost and user experience.
EpiK focuses on building a decentralized knowledge graph, which reduces data redundancy and safeguards the value of data in the distributed storage chain while preventing the knowledge graph from being tampered with by a few people, thus making the commercialization of the entire project reasonable and feasible.
From the perspective of ecological construction, EpiK treats miners more friendly and solves the pain point of Filecoin to a large extent, firstly, it changes the storage collateral and commitment collateral of Filecoin to one-time collateral.
Miners participating in EpiK Protocol are only required to pledge 1000 EPK per miner, and only once before mining, not in each sector.
What is the concept of 1000 EPKs, you only need to participate in pre-mining for about 50 days to get this portion of the tokens used for pledging. The EPK pre-mining campaign is currently underway, and it runs from early September to December, with a daily release of 50,000 ERC-20 standard EPKs, and the pre-mining nodes whose applications are approved will divide these tokens according to the mining ratio of the day, and these tokens can be exchanged 1:1 directly after they are launched on the main network. This move will continue to expand the number of miners eligible to participate in EPK mining.
Secondly, EpiK has a more lenient penalty mechanism, which is different from Filecoin’s official consensus, storage and contract penalties, because the protocol can only be uploaded by field experts, which is the “Expert to Person” mode. Every miner needs to be backed up, which means that if one or more miners are offline in the network, it will not have much impact on the network, and the miner who fails to upload the proof of time and space in time due to being offline will only be forfeited by the authorities for the effective computing power of this sector, not forfeiting the pledged coins.
If the miner can re-submit the proof of time and space within 28 days, he will regain the power.
Unlike Filecoin’s 32GB sectors, EpiK’s encapsulated sectors are smaller, only 8M each, which will solve Filecoin’s sector space wastage problem to a great extent, and all miners have the opportunity to complete the fast encapsulation, which is very friendly to miners with small computing power.
The data and quality constraints will also ensure that the effective computing power gap between large and small miners will not be closed.
Finally, unlike Filecoin’s P2P data uploading model, EpiK changes the data uploading and maintenance to E2P uploading, that is, field experts upload and ensure the quality and value of the data on the chain, and at the same time introduce the game relationship between data storage roles and data generation roles through a rational economic model to ensure the stability of the whole system and the continuous high-quality output of the data on the chain.
Deep Chain Finance:
Eric, on the eve of Filecoin’s mainline launch, issues such as Filecoin’s pre-collateral have aroused a lot of controversy among the miners. In your opinion, what kind of impact will Filecoin bring to itself and the whole distributed storage ecosystem after it launches? Do you think that the current confusing FIL prices are reasonable and what should be the normal price of FIL?
Filecoin mainnet has launched and many potential problems have been exposed, such as the aforementioned high pre-security problem, the storage resource waste and computing power monopoly caused by unreasonable sector encapsulation, and the harsh penalty mechanism, etc. These problems are quite serious, and will greatly affect the development of Filecoin ecology.
These problems are relatively serious, and will greatly affect the development of Filecoin ecology, here are two examples to illustrate. For example, the problem of big miners computing power monopoly, now after the big miners have monopolized computing power, there will be a very delicate state — — the miners save a file data with ordinary users. There is no way to verify this matter in the chain, whether what he saved is uploaded by himself or someone else. And after the big miners have monopolized computing power, there will be a very delicate state — — the miners will save a file data with ordinary users, there is no way to verify this matter in the chain, whether what he saved is uploaded by himself or someone else. Because I can fake another identity to upload data for myself, but that leads to the fact that for any miner I go to choose which data to save. I have only one goal, and that is to brush my computing power and how fast I can brush my computing power.
There is no difference between saving other people’s data and saving my own data in the matter of computing power. When I save someone else’s data, I don’t know that data. Somewhere in the world, the bandwidth quality between me and him may not be good enough.
The best option is to store my own local data, which makes sense, and that results in no one being able to store data on the chain at all. They only store their own data, because it’s the most economical for them, and the network has essentially no storage utility, no one is providing storage for the masses of retail users.
The harsh penalty mechanism will also severely deplete the miner’s profits, because DDOS attacks are actually a very common attack technique for the attacker, and for a big miner, he can get a very high profit in a short period of time if he attacks other customers, and this thing is a profitable thing for all big miners.
Now as far as the status quo is concerned, the vast majority of miners are actually not very well maintained, so they are not very well protected against these low-DDOS attacks. So the penalty regime is grim for them.
The contradiction between the unreasonable system and the demand will inevitably lead to the evolution of the system in a more reasonable direction, so there will be many forked projects that are more reasonable in terms of mechanism, thus attracting Filecoin miners and a diversion of storage power.
Since each project is in the field of decentralized storage track, the demand for miners is similar or even compatible with each other, so miners will tend to fork the projects with better economic benefits and business scenarios, so as to filter out the projects with real value on the ground.
For the chaotic FIL price, because FIL is also a project that has gone through several years, carrying too many expectations, so it can only be said that the current situation has its own reasons for existence. As for the reasonable price of FIL there is no way to make a prediction because in the long run, it is necessary to consider the commercialization of the project to land and the value of the actual chain of data. In other words, we need to keep observing whether Filecoin will become a game of computing power or a real value carrier.
Deep Chain Finance:
Leo, we just mentioned that the pre-collateral issue of Filecoin caused the dissatisfaction of miners, and after Filecoin launches on the main website, the second round of space race test coins were directly turned into real coins, and the official selling of FIL hit the market phenomenon, so many miners said they were betrayed. What I want to know is, EpiK’s main motto is “save the miners eliminated by Filecoin”, how to deal with the various problems of Filecoin, and how will EpiK achieve “save”?
Originally Filecoin’s tacit approval of the computing power makeup behavior was to declare that the official directly chose to abandon the small miners. And this test coin turned real coin also hurt the interests of the loyal big miners in one cut, we do not know why these low-level problems, we can only regret.
EpiK didn’t do it to fork Filecoin, but because EpiK to build a shared knowledge graph ecology, had to integrate decentralized storage in, so the most hardcore Filecoin’s PoRep and PoSt decentralized verification technology was chosen. In order to ensure the quality of knowledge graph data, EpiK only allows community-voted field experts to upload data, so EpiK naturally prevents miners from making up computing power, and there is no reason for the data that has no value to take up such an expensive decentralized storage resource.
With the inability to make up computing power, the difference between big miners and small miners is minimal when the amount of knowledge graph data is small.
We can’t say that we can save the big miners, but we are definitely the optimal choice for the small miners who are currently in the market to be eliminated by Filecoin.
Deep Chain Finance:
Let me ask Eric: According to EpiK protocol, EpiK adopts the E2P model, which allows only experts in the field who are voted to upload their data. This is very different from Filecoin’s P2P model, which allows individuals to upload data as they wish. In your opinion, what are the advantages of the E2P model? If only voted experts can upload data, does that mean that the EpiK protocol is not available to everyone?
First, let me explain the advantages of the E2P model over the P2P model.
There are five roles in the DAO ecosystem: miner, coin holder, field expert, bounty hunter and gateway. These five roles allocate the EPKs generated every day when the main network is launched.
The miner owns 75% of the EPKs, the field expert owns 9% of the EPKs, and the voting user shares 1% of the EPKs.
The other 15% of the EPK will fluctuate based on the daily traffic to the network, and the 15% is partly a game between the miner and the field expert.
The first describes the relationship between the two roles.
The first group of field experts are selected by the Foundation, who cover different areas of knowledge (a wide range of knowledge here, including not only serious subjects, but also home, food, travel, etc.) This group of field experts can recommend the next group of field experts, and the recommended experts only need to get 100,000 EPK votes to become field experts.
The field expert’s role is to submit high-quality data to the miner, who is responsible for encapsulating this data into blocks.
Network activity is judged by the amount of EPKs pledged by the entire network for daily traffic (1 EPK = 10 MB/day), with a higher percentage indicating higher data demand, which requires the miner to increase bandwidth quality.
If the data demand decreases, this requires field experts to provide higher quality data. This is similar to a library with more visitors needing more seats, i.e., paying the miner to upgrade the bandwidth.
When there are fewer visitors, more money is needed to buy better quality books to attract visitors, i.e., money for bounty hunters and field experts to generate more quality knowledge graph data. The game between miners and field experts is the most important game in the ecosystem, unlike the game between the authorities and big miners in the Filecoin ecosystem.
The game relationship between data producers and data storers and a more rational economic model will inevitably lead to an E2P model that generates stored on-chain data of much higher quality than the P2P model, and the quality of bandwidth for data access will be better than the P2P model, resulting in greater business value and better landing scenarios.
I will then answer the question of whether this means that the EpiK protocol will not be universally accessible to all.
The E2P model only qualifies the quality of the data generated and stored, not the roles in the ecosystem; on the contrary, with the introduction of the DAO model, the variety of roles introduced in the EpiK ecosystem (which includes the roles of ordinary people) is not limited. (Bounty hunters who can be competent in their tasks) gives roles and possibilities for how everyone can participate in the system in a more logical way.
For example, a miner with computing power can provide storage, a person with a certain domain knowledge can apply to become an expert (this includes history, technology, travel, comics, food, etc.), and a person willing to mark and correct data can become a bounty hunter.
The presence of various efficient support tools from the project owner will lower the barriers to entry for various roles, thus allowing different people to do their part in the system and together contribute to the ongoing generation of a high-quality decentralized knowledge graph.
Deep Chain Finance:
Leo, some time ago, EpiK released a white paper and an economy whitepaper, explaining the EpiK concept from the perspective of technology and economy model respectively. What I would like to ask is, what are the shortcomings of the current distributed storage projects, and how will EpiK protocol be improved?
Distributed storage can easily be misunderstood as those of Ali’s OceanDB, but in the field of blockchain, we should focus on decentralized storage first.
There is a big problem with the decentralized storage on the market now, which is “why not eat meat porridge”.
How to understand it? Decentralized storage is cheaper than centralized storage because of its technical principle, and if it is, the centralized storage is too rubbish for comparison.
What incentive does the average user have to spend more money on decentralized storage to store data?
Is it safer?
Existence miners can shut down at any time on decentralized storage by no means save a share of security in Ariadne and Amazon each.
There’s no difference between encrypted presence on decentralized storage and encrypted presence on Amazon.
The 10,000 gigabytes of bandwidth in decentralized storage simply doesn’t compare to the fiber in a centralized server room. This is the root problem of the business model, no one is using it, no one is buying it, so what’s the big vision.
The goal of EpiK is to guide all community participants in the co-construction and sharing of field knowledge graph data, which is the best way for robots to understand human knowledge, and the more knowledge graph data there is, the more knowledge a robot has, the more intelligent it is exponentially, i.e., EpiK uses decentralized storage technology. The value of exponentially growing data is captured with linearly growing hardware costs, and that’s where the buy-in for EPK comes in.
Organized data is worth a lot more than organized hard drives, and there is a demand for EPK when robots have the need for intelligence.
Deep Chain Finance:
Let me ask Leo, how many forked projects does Filecoin have so far, roughly? Do you think there will be more or less waves of fork after the mainnet launches? Have the requirements of the miners at large changed when it comes to participation?
We don’t have specific statistics, now that the main network launches, we feel that forking projects will increase, there are so many restricted miners in the market that they need to be organized efficiently.
However, we currently see that most forked projects are simply modifying the parameters of Filecoin’s economy model, which is undesirable, and this level of modification can’t change the status quo of miners making up computing power, and the change to the market is just to make some of the big miners feel more comfortable digging up, which won’t help to promote the decentralized storage ecology to land.
We need more reasonable landing scenarios so that idle mining resources can be turned into effective productivity, pitching a 100x coin instead of committing to one Fomo sentiment after another.
Deep Chain Finance:
How far along is the EpiK Protocol project, Eric? What other big moves are coming in the near future?
The development of the EpiK Protocol is divided into 5 major phases.
(a) Phase I testing of the network “Obelisk”.
Phase II Main Network 1.0 “Rosetta”.
Phase III Main Network 2.0 “Hammurabi”.
(a) The Phase IV Enrichment Knowledge Mapping Toolkit.
The fifth stage is to enrich the knowledge graph application ecology.
Currently in the first phase of testing network “Obelisk”, anyone can sign up to participate in the test network pre-mining test to obtain ERC20 EPK tokens, after the mainnet exchange on a one-to-one basis.
We have recently launched ERC20 EPK on Uniswap, you can buy and sell it freely on Uniswap or download our EpiK mobile wallet.
In addition, we will soon launch the EpiK Bounty platform, and welcome all community members to do tasks together to build the EpiK community. At the same time, we are also pushing forward the centralized exchange for token listing.
Some KOLs said, Filecoin consumed its value in the next few years, so it will plunge, what do you think?
First of all, the judgment of the market is to correspond to the cycle, not optimistic about the FIL first judgment to do is not optimistic about the economic model of the project, or not optimistic about the distributed storage track.
First of all, we are very confident in the distributed storage track and will certainly face a process of growth and decline, so as to make a choice for a better project.
Since the existing group of miners and the computing power already produced is fixed, and since EpiK miners and FIL miners are compatible, anytime miners will also make a choice for more promising and economically viable projects.
Filecoin consumes the value of the next few years this time, so it will plunge.
Regarding the market issues, the plunge is not a prediction, in the industry or to keep learning iteration and value judgment. Because up and down market sentiment is one aspect, there will be more very important factors. For example, the big washout in March this year, so it can only be said that it will slow down the development of the FIL community. But prices are indeed unpredictable.
Actually, in the end, if there are no applications and no one really uploads data, the market value will drop, so what are the landing applications of EpiK?
Leo: The best and most direct application of EpiK’s knowledge graph is the question and answer system, which can be an intelligent legal advisor, an intelligent medical advisor, an intelligent chef, an intelligent tour guide, an intelligent game strategy, and so on.
Founded in 2014, after 6 years of R & D as well as its expansion, and after nearly a year of extensive testing and preparation, IPFS (Interplanetary File System) was officially launched on the afternoon of October 15, 2020, UTC time. 12 hours after the mainnet went online, Its token price fluctuated between 50~70 USD/FIL. However, panic and pessimism began to spread between the IPFS community and FIL token holders. Based on the total amount of FIL (2 billion) and the unit price of 50 US dollars estimation, its market value has exceeded 100 billion US dollars, second only to BTC. As such a mega valued IPFS/FIL went online, if there is no enough application to support, the selling pressure after the FIL is gradually unlocked will become huge. According to calculations, on the first day of the mainnet launch, there will be 239,000 FILs to be sold. Assuming that the unit price is 30 USD, the released circulation will be 8 million USD. Assuming the unit price remains unchanged, the market will usher in a similar value on the 10th day. With a release amount of 15 million USD, it is very likely that the corresponding token price can be supported.submitted by Hayley_HOP to u/Hayley_HOP [link] [comments]
IPFS is a network transmission protocol designed to create persistent and distributed storage and sharing of files. In terms of its current active projects and companies, IPFS has added more than 5 billion files, involving multiple industries, and there are also many blockchain companies using this technology. When the IPFS mainnet and its Filecoin goes online, the market value will be based on the applications brought by the IPFS network. After Bitcoin and Ethereum, Filecoin is an upstart in the blockchain industry with a revolutionary technological breakthrough. The market predicts that Filecoin’s market value will surpass Bitcoin. Now let us analyze this project together that was given high hopes:
IPFS major features and disadvantages
The basic application of IPFS, Filecoin’s financial attributes and its incentive mechanism make it a very exciting global collaborative open source project. On this basis, the data of all mankind is stored in the IPFS network, and no one can tamper with it.
This magnificent scene provides at least three values for us:
What is HOP
The HOP protocol provides a decentralized and completely anonymous traffic service for people all over the world based on block chain. HOP combines P2P network transmission and block chain technology to establish a block chain micro-payment protocol based on the block chain transmission encryption protocol between P2P network bandwidth contributors and bandwidth users, and merge it into traffic mining. In the mining pool side, the whole protocol is built on the main network, which has Micro Payment and mining functions. In addition, HOP also supports traffic mining of ERC20 in any currency. So far, HOP is the only protocol that combines the above functions and is officially available in commercial application. It can provide terminal nodes for secure access to decentralized networks.
HOP features and comparison with IPFS
HOP and IPFS have certain similarities. The following table is a comparison of the two projects in terms of technology and application characteristics:
Why HOP might be a phenomenal project in the future
Compared with the disadvantages of IPFS which are not supporting for hot data storage, low storage efficiency, low disaster tolerance and the high threshold of providing storage capacity, The advantages of HOP are summarized as follows:
At present, most of the participants of HOP are top tier tech specialists, famous investors and politicians with global vision. We believe that projects like HOP, due to the open source and far-sighted technical foundation, which can not only achieve internal self-consistent circulation, but also integrate well with external ecology. Just as water conservancy is invisible, HOP has unlimited inclusiveness and scalability, and has a strong platform-level vitality!
We are looking forward to the accumulation of HOP, bringing a revolution in technology and applications to the blockchain and the practical universe!

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 feesAs 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 shardDeFi 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 perfectMulti-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 MiningIn this phase, all the community members can have the experience to use our two new products:
QSwap: Multi-native token version UniswapUnlike 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 gameThe 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?

Ethereum cryptocurrency that comes second in terms of capitalization on the crypto market is traditionally seen as fast and profitable. However, over the last few weeks it's had a rough patch. Since early August, the network has had huge queues of transactions pending processing while fees have skyrocketed and surpassed the historical high.
The main issue though is that even fees of a few dollars per transfer don't help get rid of the“traffic jams”. The cause of this is numerous DeFi projects and a huge number of financial pyramids based on the Ethereum platform. Both generate excessive load on the network.
The situation is downright unpleasant, and our users might question whether the UMI network could face a similar challenge? We'd like to assure you it could not. The UMI network is by default protected against these problems — it cannot have “traffic jams”, fees or financial pyramids. But first things first.
How has the Ethereum network ground to a halt?
In its report dated August 4, Arcane Research that provides analysis within the field of cryptocurrency stated that over the previous week the daily size of transaction fees in the Ethereum network has surged up to a record high for over two and a half years. On August 3, the median value #%D0%9F%D1%80%D0%B8%D0%BC%D0%B5%D1%80_%D0%B8%D1%81%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F)of the fee amounted to $0.82, with the overall amount of transaction fees totaling $2 mln. However, it only signaled the start of real problems.
Over the next week, fees continued to grow and by August 11 the median fee value almost doubled equaling $1.57. Larry Cermak, an expert at a big analytical and news-making crypto portal The Block, wrote in his August 15 tweet that over a week the total amount of transaction fees in the Ethereum network totaled $34.5 mln, having surpassed its historical high. Meanwhile, in the Bitcoin network that is seen as too expensive the fees were almost four times lower at $9 mln.
The total fee amount paid by cryptocurrency users over a week:
Historical Growth Chart for Ethereum Fees. Source
The existing situation shows that Ethereum is actually not as fast and profitable as commonly cited. Additionally, this could happen to almost any cryptocurrency except UMI that charges no fees whatsoever. We will tell you why.
Why have these problems emerged?
There is nothing unoriginal: the Ethereum network simply can't handle an increased load. Arcane Research analysts consider that a principal cause of this situation is the constantly increasing number of the DeFi ecosystem projects built on the Ethereum blockchain. Their number is growing all the time which causes the overload of the network. As of August 12, the total amount of funds in DeFi applications reached $4.3 billion which is 19.5% higher than that in the past week. At the time of writing this article, the amount surged to $6.21 billion. You can see the current data here. What is the most unpleasant about DeFi protocols is that a lot of them are scam projects.
Which is not the worst part though. There is also another factor that significantly slows down the Ethereum network. There are a lot of pyramid-like projects that are built on the EOS platform and use smart contracts. One of them is SmartWay Forsage, which regularly overloads the network with a large number of transactions, causes traffic jams, and, consequently, leads to increased fees (keep in mind that Ethereum miners choose transactions with a higher commission). Vitalik Buterin, the co-founder of Ethereum, revealed his disapproval of the SmartWay Forsage methodology and asked them to "leave and not pollute Ethereum ecology in the future". However, the project is slow to do this — it continues to deceive users.
This is only the tip of the iceberg of scam projects which abounds on the EOS network –– they continually emerge, work for a while, then go down as scams and are replaced with new ones. This never-ending stream of "investment projects" based on the Ponzi scheme overloads the system. This is the reason why Adam Back, a pioneer of the crypto industry and founder of the technology company Blockstream, equated Ethereum with such infamous projects as Onecoin and Bitconnect. Adam Back's solid dig at Ethereum became the subject of much debate among crypto enthusiasts.
Of course, it all doesn't mean that Ethereum is a bad cryptocurrency. On the contrary, it has a lot of advantages over other coins. But all that has happened exposes Ethereum's faults which must be eliminated. The problem is that they may not be fixable. It is far from certain that the developers will be able to get rid of all the defects as the system has huge scalability problems.
The crypto community has to admit that Ethereum, like other first-generation cryptocurrencies, has issues with capacity, fees, and scalability and is gradually becoming obsolete.
2020 is the time for young innovative cryptocurrencies such as UMI.
UMI is the flagship of new-generation cryptocurrencies.
In real fact, any cryptocurrency could face it. Each cryptocurrency charges fees which typically surge when the network is overloaded or the price is going up. Everyone will remember 2017 when in line with price growth and the network's overload Bitcoin transaction fee reached a high of around $40.
But when it comes to UMI, it works the other way round. The UMI network's advantages are high capacity, no fees, and scaling possibilities. It uses the best and fastest crypto industry solutions and excludes all inefficient methods by default. Smart optimization in combination with the Proof-of-Authority technology operating on the master node basis enables almost instant payments.
At the stage of network testing, an incredibly high capacity was achieved:
The UMI network can process transactions that Ethereum processes over a year in a few days and with no fees. More details
What is more important is that less than 0.001% of the network's overall potential is used now. The UMI network has a lot of reserve capacity and can handle hundreds of thousands of times heavier load. Moreover, with scaling possibilities, UMI can keep up with the times. The UMI code ensures the safe introduction of any upgrades — the network can be easily modified and scaled with cutting edge technology solutions. In other words, traffic jams will never pose a problem for us. UMI will instantly process all transactions, with no fees. Always.
A real-time speedometer displays the number of transactions processed by the UMI network per second. Link
Additionally, unlike Ethereum and other cryptocurrencies, the UMI's staking smart contract prevents possibilities of any pyramid schemes, meaning eliminates their negative influence. Our staking is completely safe and secured against scammers. Read more about this in our article. Any UMI staking structure could work forever. In other words, you can multiply your coins at a rate of up to 40% per month for an indefinitely long period of time.
UMI doesn't inherit the disadvantages of the first-generation cryptocurrencies. This is an innovative, carefully designed network based on state-of-the-art technologies. UMI is an ambitious step toward the future. And we're making it together right now!
Sincerely yours, UMI team
With the development of blockchain technology, obtaining data on the chain only is no longer satisfying and how to bridge the real world and the blockchain world has always been the direction of the technological breakthrough. Under this background, Oracle Machine came to our attention. In particular, with the popularity of the DeFi concept, the industry starts to witness a boom of the application of Oracle Machine in financial derivatives, trading platforms, gambling games, and prediction markets.submitted by ThemisOracle to u/ThemisOracle [link] [comments]
At present, Oracle Machine represented by Themis is developing fast with a good momentum, leading the trend of the development of Oracle Machine and continuing to consolidate the basic technical support for the DeFi revolution. Themis’ mining system has been launched in the market, which is refreshing and appealing (see https://themisoracle.com/#/credit for details on the Themis mining).
90% of MIS, the native token of Themis, will be used for mining output. The entire mining mechanism runs through a distributed oracle protocol, which sets up three roles: data provider, data validator, and arbitration node. Reward and punishment mechanisms are applied to ensure the smooth ecological operation.
How does Themis mining work? Is it a new way to become wealthy? What are the characteristics? To answer these questions, we need to analyse the distribution mechanism, mining mechanism, and token value of Themis.
With a fairer mining mechanism, small and medium-sized miners can enjoy better benefits
One of the core values of blockchain is fairness and justice, and allowing everyone in the network to play a role in the system without permission. However, Bitcoin mining is now monopolized by several mining machine vendors such as Bitmain, leaving little space for other miners to participate. If those old PoW public chains, such as Bitcoin, has formed the head effect in mining, what about those new projects? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked top with the strong financial strength and user base of the top exchange, making the small and medium nodes hard to participate.
After comparison, we can find that the mining mechanism of MIS is very friendly to ordinary users. Assuming that there are 12 mining transactions in a block, the ranking according to the MIS pledged by each transaction would be as follow:
The pledge ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user pledge amount, which can prevent MIS from being controlled by a small number of people, avoid monopoly, creating a win-win situation in the Themis community.
Compared with other mining projects, Themis has introduced a unique pledge ranking method in the mining design. Users in the best ranking area will get the most benefits, which is a good mechanism guarantee for attracting more users to participate in mining. At the same time, it can lead to the decentralization of data providers, ensuring the decentralization of the oracle system and the positive development of the community.
How can miners join in Themis mining? The answer is to become a part of the ecology by playing the role of either data provider, data validator, or arbitration node.
The data provider is mainly responsible for providing various types of data, and the data validator verifies and challenges the data offered by the data provider and provides new data. The arbitration node arbitrates the query raised by the data validator and come up with the final result.
Both the data providers and validators of Themis need to pledge MIS to obtain the qualifications, and the caller of external data also needs to pay MIS assets when accessing the data of Themis oracles. If the data has been verified as correct, data providers and validators will receive mining rewards, and the more they pledge, the more rewards they will receive.
In the mining design of Themis, miners can acquire MIS by providing verifiable random number or offering the price of in-chain assets. Whenever miners call mining contracts, the system will charge no service fee (excluding the service fee of ETH). In addition, if no mining transaction occurs within a certain period of time, the first newly-emerging block containing mining transactions will acquire all the MIS rewards. In this way, miners can be encouraged to continue mining and maintain the ecological stability of Themis.
The number of MIS mining for each mining transaction of miners is calculated as follows:
First, calculate the number of MIS mining rewards N contained in the block of the packaged mining transaction. If the height difference between the block and the previous block containing the mining transaction is y, then N = y * 20.
The MIS mining quantity of this mining transaction is M, then M=Xi/(📷)×N. Among them, X is the ranking of the MIS pledge amount in the block, and those who pledge the same amount of MIS have the same ranking.
Few official pre-mining, while 90% belongs to the community
Based on the official announcement, the distribution of MIS is:
The total amount of MIS is 1 billion, 10% is reserved for early project promotion, the remaining 90% are produced by mining, in which 75% are directly awarded to data providers, 10% to developers, and 5% as reward for arbitration nodes and ecological incentive. The production of mining will be progressively decreased and released with ETH. For some current popular VC-invested projects, institutional holdings hold more than half of blocks and unlock the block every month, which is a huge stress for ordinary pledge users. Many projects also went wrong because institutional investors do not abide by the rules. For MIS, because there is fewer official pre-mining, the selling pressure will be smaller, which is more in line with the value of the blockchain.
The release plan of developer and arbitration node and ecological incentive is as follows:
The release plan of data provider incentive is as follows:
The MIS awarded per block reduces by 10% in every 4 million blocks, and the reward per block at present is 20 MIS.
We can see that the allocation of MIS follows the following principles.
First of all, as MIS is the platform certificate of Themis, it is very reasonable to reserve 10% of MIS for early project promotion.
Secondly, 90% of MIS is produced through sustainable mining. This proportion can motivate contract users and miners to conduct contract mining, truly implementing the spirit of win-win community and token economy.
Finally, among the 90% of MIS, better incentive mechanisms have been adapted, mining reward ratios are subdivided, which can attract more investors to participate in mining.
Reasonable mining mechanism highlights the project value of Themis
Themis, as a public chain that provides a mechanism to solve the problems in Oracle Machine, has a unique charm in the value of MIS.
From the perspective of the number of tokens, the total amount of MIS is 1 billion, and the total mining pool is 900 million. 90% of the tokens are generated by mining, and the mining output gradually decreases its release with the Ethereum block, showing a great potential in its future added value. The earlier you participate in mining, the more profit you can gain.
From the perspective of Themis’s ecological design, Themis is committed to the original intention of building a price oracle. The data provider pays on-chain fees and pledges a certain amount of MIS, and determines the income obtained according to the scale of the pledge; the validator can make profit from challenging the data. Also, any smart contract developer or user need to pay the corresponding fee when calling Themis, and this part of the profit will be distributed to the data provider in proportion. Through this design, a logical closed loop is completed to ensure the healthy operation of the entire ecology and achieve the goal of mutual benefit. In Themis, all parties in the ecology can work together to grow more wealth.
In all, MIS has a huge potential for future development and arbitrage, and of course, a great profit potential as well.
Today, public chains like Themis are not just a technology platform, but also a symbol of future economic operation mode which connect between the blockchain and the real world. Themis, with a fair, justice and open network through mining, is building a strong token ecology, connecting external chain data and the systems, realising data interaction between blockchain and the real world, and more importantly, creating a new mode of token economy.

The consensus mechanism is one of the important elements of the blockchain and the core rule of the normal operation of the distributed ledger. It is mainly used to solve the trust problem between people and determine who is responsible for generating new blocks and maintaining the effective unification of the system in the blockchain system. Thus, it has become an everlasting research hot topic in blockchain.

Figure 6 Summary of relatively mainstream consensus mechanisms
Source: Hasib Anwar, "Consensus Algorithms: The Root Of The Blockchain Technology"
The picture above shows 14 relatively mainstream consensus mechanisms summarized by a geek Hasib Anwar, including PoW (Proof of Work), PoS (Proof of Stake), DPoS (Delegated Proof of Stake), LPoS (Lease Proof of Stake), PoET ( Proof of Elapsed Time), PBFT (Practical Byzantine Fault Tolerance), SBFT (Simple Byzantine Fault Tolerance), DBFT (Delegated Byzantine Fault Tolerance), DAG (Directed Acyclic Graph), Proof-of-Activity (Proof of Activity), Proof-of- Importance (Proof of Importance), Proof-of-Capacity (Proof of Capacity), Proof-of-Burn ( Proof of Burn), Proof-of-Weight (Proof of Weight).
Next, we will mainly introduce and analyze the top ten consensus mechanisms of the current blockchain.
Delegated Byzantine fault tolerance. The improved Byzantine fault-tolerant algorithm makes it suitable for blockchain systems. The system consists of nodes, delegators (who can approve blocks), and speakers (who proposes the next block). It is a consensus algorithm that guarantees fault tolerance implemented inside the NEO blockchain.
In this mechanism, there are two participants: the professional bookkeeper "bookkeeping node" and the ordinary users in the system.
Ordinary users vote based on the proportion of holding stake to determine the bookkeeping node. When a consensus is required, a spokesperson is randomly selected from these bookkeeping nodes to draw up a plan, and then other bookkeeping nodes will vote basing on the Byzantine fault tolerance algorithm.That is, majority principle. If more than 66% of the nodes agree to the spokesperson’ plan, a consensus is reached; otherwise, the spokesperson is re-elected and the voting process is repeated.
-Representative application: Neo, etc.
Proof of authority. That is, certified by some accredited accounts, these accredited accounts are called "validators". The software that the verifier runs that supports the verifier to place transactions in blocks.
-Representative applications: VeChain, etc.
Directed acyclic graph. Each newly added unit in the DAG is not only added to the long chain block, but added to all the previous blocks, verifying each new unit and confirming its parent unit and the parent unit of the parent unit, and gradually confirming until the genesis unit. As the hash of its parent unit is included in its own unit, the blockchains of all transactions are connected to each other to form a graph-like structure with time.
In the DAG network, each node can be a trader and a validator, because the transaction processing in DAG is done by the transaction node itself. Taking IOTA as an example, IOTA’s Tangle led
ger does not need to pay transaction fees while ensuring high-speed transaction processing. However, it does not mean that the transaction is free, because in this ledger, the initiation of each transaction needs to verify the other two random transactions first, and connect the transaction initiated by itself to these two transactions, so the responsibility that miners on the blockchain bear is distributed to all traders. The DAG method of processing transactions can be called asynchronous processing mode.
Figure 10 The difference between the traditional blockchain structure and the DAG structure
-Representative applications: IOTA, etc.
Proof of elapsed time. That is, it is usually used in a permissioned blockchain network. It can determine the mining rights of the block holders in the network. The permissioned blockchain network requires any prospective participants to verify their identity before joining. According to the principles of the fair lottery system, each node is equally likely to become the winner.
Each participating node in the network must wait for a randomly selected period, and the first node to complete the set waiting time will get a new block. Each node in the blockchain network will generate a random waiting time and sleep for a set time. The node that wakes up first, that is, the node with the shortest waiting time, wakes up and submits a new block to the blockchain, and then broadcasts the necessary information to the entire peer-to-peer network. The same process will be repeated to find the next block.
Proof of stake velocity. Proposed by Reddcoin, drawing on the concept of "money circulation speed" in economics, it mainly allocates bookkeeping rights based on the coin age of nodes participating in the competition.
PoSV also allocates accounting rights according to the coin age of the nodes participating in the competition, but modifies the coin age calculation formula to a function of exponential decay of growth rate. Taking Reddcoin as an example, Reddcoin sets the half-life of the coin age growth rate to 1 month. Assuming that the unit token can accumulate 1CoinDay coin age on the first day, only 0.5CoinDay coin age can be accumulated on the 31st day, and only 0.25CoinDay coin age can be accumulated on the 61st day, and so on. In this way, the nodes are encouraged to use the token to conduct a transaction after holding the token for a period of time, thereby restarting the calculation of the coin age and increasing the circulation speed of the token in the network.
-Representative applications: Reddcoin, etc.

Chapter 4 Summary of the Selection and Status Quo of Consensus Mechanism
4.1 How to choose a consensus mechanism that suits you
Step 1: Determine whether the final result is important
For some applications, the end result is very important. If you are building a new payment system that can support very small amounts, it is acceptable for the transaction result to change. Similarly, if you are creating a new distributed social network, 100% guarantee that the status is updated immediately is not particularly necessary. On the contrary, if you are creating a new distributed protocol, the final result is critical to the user experience. For example, Bitcoin has a final confirmation time of about 1 hour, Ethereum has a final confirmation time of about 6 minutes, and Tendermint Core only has a final confirmation time of 1 second.
Step 2: Determine how fast the application process needs to be
If you are building a game, is it reasonable to wait 15 seconds before each action? Due to the low block processing time of Ethereum, games built on it will cause poor user experience due to Ethereum's throughput. However, the application for the transfer of housing property rights can be run on Ethereum. Use the Cosmos SDK to build an application that allows developers to freely use Tendermint Core. It has a short block processing time and high throughput, and is capable of processing 10,000 transactions per second. You can reduce the required communication overhead and speed up the application by setting the maximum number of validators for the application.
Step 3: Determine the application's demand for decentralization
Some applications such as games may not require very high censorship resistance as a by-product of decentralization. In theory, does it really matter that the validator can create a cartel in the game and reverse the transaction result for profit? If it is not important, a blockchain such as EOS may be more suitable for your needs because of the fast transaction speed and free fees. However, some applications such as autonomous banks are more powerful and decentralized. Although Ethereum is considered to be decentralized, some supporters claim that Ethereum's mining pool is an important part of centralized platform, although there are actually only 11 validators (mining pools). One of the major benefits of building your own blockchain instead of building on a smart contract platform is that you can customize the way the application completes verification. However, it is difficult to build your own blockchain, so the Cosmos SDK is very useful, you can easily build your own blockchain and customize the degree of decentralization you need.
Step 4: Determine whether the system can be terminated
If you are building a new application similar to a distributed ride-sharing service, then ensuring 24/7 service must be the first priority, even if there are occasional errors in accounting similar to transactions. One of the properties of Tendermint Core is that if there is a disagreement between network validators, the network will suspend operations instead of proceeding erroneous transactions. Applications such as decentralized exchanges require correctness at all costs-if there is a problem, it is far better to suspend trading on the decentralized exchange than there may be trading problems.
Summary: Choose a suitable consensus algorithm after weighing the advantages and disadvantages
All in all, there is no single best consensus algorithm. Each consensus algorithm has its own value and advantages. You need to have your own judgments and choices. However, by understanding the relevant processes of the consensus mechanism, including proposals and agreements, and establishing a framework to consider the types of consensus algorithms that your application may require, you should be able to make wiser decisions.
4.2 Future development of consensus mechanism
The consensus algorithm is one of the core elements of the blockchain. Although there are more than 30 consensus mechanisms listed in the article, there are still many niche consensus mechanisms that may not be discussed. As the blockchain technology is gradually known and accepted by the public, more and more newer and better consensus algorithms may appear in the future, which may be brand-new consensus algorithms, and more should be improvement and optimization version based on the current consensus algorithm.
After 2016 and 2017 years’ fast development, the current consensus algorithm does not have a recognized evaluation standard, but is generally more biased towards fairness and decentralization, as well as some technical related issues, such as energy consumption and scalability , Fault tolerance and security, etc. However, blockchain technology must be combined with requirements and application scenarios, and the consensus mechanism algorithm and incentive mechanism are inseparable. How to customize a suitable consensus mechanism according to the characteristics of your own project and optimize the current consensus mechanism will become the future direction of consensus mechanism development
As the first DPOW financial blockchain operating system, CelesOS adopts consensus mechanism 3.0 to break through the "impossible triangle", which can provide high TPS while also allowing for decentralization. Committed to creating a financial blockchain operating system that embraces supervision, providing services for financial institutions and the development of applications on the supervision chain, and formulating a role and consensus ecological supervision layer agreement for supervision.
The CelesOS team is dedicated to building a bridge between blockchain and regulatory agencies/financial industry. We believe that only blockchain technology that cooperates with regulators will have a real future. We believe in and contribute to achieving this goal.
