Dpos pool ranking

POW: full name of proof of work

pos: proof of stake

both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency

the difference is:

1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power

POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbers

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

2. POC: (proof of credit) credit consensus mechanism is initiated and applied by the nuls team. The consensus mechanism is: when the node's credit reaches the standard, a certain margin can be locked to join the consensus. After the consensus node is reordered, the block will be released in turn in each round, and the margin will be unlocked when it exits the consensus. The POC of nuls is divided into entrustment consensus and node consensus. Entrustment consensus mortgage 2000nuls and node consensus mortgage 20000nuls. The node builder maintains the node and receives part of the commission from the delegation consensus to jointly maintain the healthy operation of the nuls main network node
POC consensus mechanism integrates the advantages of pow / POS / dpos, and achieves better coordination of decentralization, efficiency and consistency in different directions, which are difficult to unify in blockchain< br /> 
1. Decentralization: in the POC consensus mechanism, there is no rigid limit on the number of nodes. The number of nodes is dynamic, and anyone who meets the conditions can join the nodes. Here, each outgoing node is similar to the mine pool in the pow, and can join the consensus in the mine pool by holding interests. In the pow, the pool obtains the bookkeeping rights according to the computing power. In the POC, the chance of all the pools to obtain bookkeeping rights is random and equal, which makes the node distribution of the consensus mechanism of POC more decentralized< br /> < br /> 
2. Efficiency: the two key factors affecting the efficiency of blockchain network are the degree of wide distribution of nodes and the hardware network resources provided by nodes. In the coordination of these two parameters, POC consensus mechanism introces the credit coefficient mechanism, which directly affects the stability of the node. Therefore, each node and the principals participating in the node will make the most favorable choice for the network to ensure that the node can provide services efficiently and stably. In addition, they will join the node consensus by means of rights and interests, The number of nodes will float in a certain range, which can be adjusted by changing the incentive parameters. When the parameters are fixed, the market will adjust automatically. In these nodes, the dpos principle of random sorting out blocks is integrated, which ensures the security and efficiency of the network and provides higher TPS carrying capacity< br /> 
3. Consistency: in the POC consensus mechanism, all members can participate in the consensus, and the node can only charge a certain fee to the participants. All people have equal opportunities to participate in the consensus, and the incentive is determined by the equity and node credit coefficient. Nodes and all participants will reach a consensus in order to provide stable node services.

3. Chain capital is a blockchain + cloud computing technology service provider; Its main business is CAAP ore pool. It has physical mines in many regions of the world, and has deployed thousands of the latest mining machines. Its main business is to provide cloud computing power services for blockchain technology. It is not only doing the consensus mechanism of pow workload proof, but also has the consensus mechanism of POS, dpos and other equity proof
there are two ways of investment: 1. Investment of mine pool fund, with an initial investment amount of 100000 to several hundred thousand; The investment cycle is half a year, and the income is higher than that of general bank financial procts. 2. Recently, the popular version of mine pool computing power investment is launched, with low threshold and stable income, mainly through leasing personal computing power to obtain a certain proportion of income; The income mainly depends on the amount of investment, the amount of calculation and the age of calculation. When the market performance of blockchain is not good, the proportion of revenue decreases or at most there is no revenue, which will not affect their own money

4. Lightning bitcoin has not been well known because it is a bifurcated coin of bitcoin. Many users in the coin circle instinctively dislike this kind of token. Fork coin has now become synonymous with money and running. But what you may not know is that all bifurcated bitcoin can be called currency in the eyes of foreign regulators. The US SEC only recognizes bitcoin and Ethereum as currencies because they have not concted ICO in public channels. Accordingly, these bifurcated currencies are regarded as currency. And lightning bitcoin is the only one that doesn't pre dig in the fork coin. You can imagine that bitcoin is 100 banknotes issued by a bank, and all kinds of bifurcated banknotes are equivalent to banknotes of different denominations issued by the bank. You may not be able to understand the valuable value of this. When it comes to the circulation of entities, if you are a bifurcated coin of bitcoin, it is easy to pass the government compliance. In short, the reason why the Grand Prince BCH can get through the physical circulation in Japan so quickly is just the light of bitcoin
then why should I say that lightning bitcoin is a great currency experiment? We compare lightning bitcoin to a free economy with three major stakeholders: developers, miners and holders

so far, no blockchain project can effectively govern the three. Why? The reason is very simple. In an ICO project, the developers, coin holders and even miners are the same group. It's easy to understand. Why should he give the best interests to the ICO holders? This is obviously not in line with human nature. The reason why lightning bitcoin dares to do chain governance is related to the issuing mode of lightning bitcoin. LBTC's "governance on the chain" is another attempt to "decentralize", which is also very eye-catching. Dpos mechanism determines that there are 101 nodes in the network. At the same time, unlike pow, the right of choice is in the hands of the coin holder. These nodes will be elected by the vote of the coin holder. When the node does not act, the user can vote out of the network. According to last week's weekly report, LBTC's block browser has also added this function, which can view the operation of nodes in real time. It also paves the way for LBTC's "chain governance". In the LBTC system, all coin holders can vote to decide whether the project development proposal will go or stay, and all members of the organization can participate in the decision-making and operation of the organization. In addition, the 5000 standard of lockup after the election of the lightning node ensures that the node is both a mine pool and a coin holder. In this way, the relationship among miners, developers and users is well balanced, and the foundation of an autonomous organization is formed.

5. "Mining" in the blockchain is the process of bookkeeping. You can purchase computing power equipment, that is, "mining machine", to "mine" and get bookkeeping rewards
however, with the increasingly fierce competition in bookkeeping and the graal rise of dpos, ordinary computing power equipment has been unable to meet the needs of mining
it is necessary to purchase more professional mining machines or join large mines. Therefore, the threshold of mining is slightly higher
where there is demand, there is market
e to the increasing market demand for professional mining machinery, more and more chip enterprises increase investment in chip R & D, and start to develop mining machinery with higher computing power and lower energy consumption, so as to earn profits
when the currency price rose sharply in 2017, this kind of mining machinery was in short supply
as the level of computing power in the whole network is getting higher and higher, it is difficult for a single miner to seize the bookkeeping right and obtain bookkeeping rewards. Therefore, the way of combining a small amount of computing power and joint operation arises at the historic moment to improve the competitiveness of bookkeeping
the website established in this way is called "mine pool"
the profit model of the mine pool is to charge the handling charge. The more people participate in the mine pool, the higher the proportion of handling charge, the higher the income of the mine pool company
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

6. Take our life as an example. When you buy things on double 11, tmall's sales of more than 100 billion a day and huge digital computing are applied to cloud computing
there are also agricultural procts like rice, oil and so on
for example, vonetracer traceability system of wangchain technology is related to us.

7. Even if you open a small exchange, no one is willing to trade. It's just like why you choose tmall and Jingdong for online shopping. At least they are powerful and reassuring. Large mainstream exchanges have a high threshold for issuing currency. They often pay millions of US dollars for the money. They filter out most of the money. Although they are cutting leeks, they have a high degree of trust, The release time can last a little longer. In addition, most importantly, can you afford to pay for account theft? It's all money. Is it expensive to register a website like Alibaba? There is one truth.

8. Dpos: delegated proof of stake, certificate of rights and interests
PS: for details of this agreement, please refer to the latest blog "detailed explanation of [blockchain] dpos official consensus mechanism (BTS / EOS)"
the dpos mechanism of bitshares is called share authorization proof mechanism (also known as trustee mechanism) in Chinese, and its principle is to let everyone holding bitshares vote, Thus, 101 representatives are generated, which can be understood as 101 super nodes or ore pools, and the rights of these 101 super nodes are completely equal to each other. In a way, dpos is a bit like a parliamentary system or a people's Congress system. If the delegates can't perform their ties (when it's their turn, they can't generate blocks), they will be removed and the network will choose a new supernode to replace them. The emergence of dpos is mainly e to the proction of mining machines. A lot of computing power is on people who don't understand and care about bitcoin. Scalpers like concerts hoard a lot of tickets and don't care about the content of concerts at all.

9. The POV consensus is to vote for mining
on the basis of POS consensus, a unique design is added, that is, the voting right can be transferred to the role of a similar mine pool, so that the mine pool can replace mining. When users get mining income, the mine pool will charge the corresponding handling fee. Compared with the traditional dpos consensus, the POV is more decentralized, and the dpos weight is controlled by large nodes, while the pool with the POV consensus weight at the tail still has the opportunity to block. Compared with the pow consensus, it does not need to waste a lot of computing power and resources to mine, but also can achieve decentralized decentralization like pow.
