POC pool ranking

1. The specific ranking is not clear, but the better ones are Xinghuo, Duomi, Yuchi, BW and so on. It is said that BW is good. It was established in 2013 and it is a well-known old mine

2. At present, BTC ranks first, such as digyi mining, which operates bitcoin, lightcoin and Ethereum. The computing power of bitcoin mine accounts for about 4% of the total network computing power, ranking among the top ten mines in the world, and is very famous in China.

4. At present, most POC currencies in the market are proced on the assembly line
its speculative value is far greater than the mining value
participation is not recommended.

POC is the abbreviation of proof of concept, which means to provide evidence for opinions. It is a set of suggested electronic models, which can be used to demonstrate the design of teams and customers, and allow to evaluate and confirm the conceptual design scheme. The evaluation of POC may cause the adjustment of specifications and design

function:

the commitment of design and the opinions recognized by all will be recorded in the design adjustment document for future reference. In this way, POC continues to develop. If you need help completing these tasks, you can find assistance resources at Queensland University

extended data:

evaluation and verification of POC

the process of evaluation and verification is to seek feedback from risk takers through POC and filing design documents. Through POC evaluation, risk takers may put forward requirements for adjusting specifications and design

sometimes, e to design defects or inappropriate places, the design team may have to go back to the drawing board. Customers may decide to stop designing or look for other teams because the design does not pay enough attention to the needs of customers and users, or because of the instability of customer needs

sometimes the change is caused by the customer organization or project decision-maker. Generally, at the end of the evaluation and verification process, the design commitment and the opinions accepted by all will be recorded in the design documents

this is often an important milestone in the life cycle of proct development. After the evaluation and verification, POC can continue to develop

7. 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.

9. Let me tell you this: POW has almost all the advantages and POCS have none of the disadvantages. Bitcoin's pow consensus mechanism has obvious shortcomings: energy waste, noise, mining centralization. The cost of bitcoin mining is getting higher and higher, and the computing power is concentrated in several large mines, so it is difficult for ordinary users to participate; HDFS adopts POC mechanism for hard disk mining, so that everyone can mine.
