The method of MPOs ore pool

1. The proction of virtual currency needs a professional team, but if you make a direct currency, there is no wallet, there is no maintenance, and it's just a pure number, it's much simpler, the cost is very low, and a trading platform is thousands of yuan. However, there are serious loopholes in this platform and it is easy to be attacked
if you want to create a virtual currency like bitcoin, Ruitai coin and Qianjin card, you need to make some efforts. First of all, these coins need card method and a downloadable wallet. The application scenarios of this kind of currency have been determined. At the same time, you need to create a secure and reliable trading platform.

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

3. Building a mine pool is not so simple, enough servers, enough computing power

4. Bitcoin is also "g" out, but it is mined out in the virtual network world by computers (which we generally call "mining machine"). Therefore, to dig money, we also need to select a suitable area, build a factory, connect hundreds of mining machines and dig together. This is the mine

the cost of a mine includes construction cost, equipment cost, maintenance cost, network cost, etc. The maintenance cost includes the cost of electricity and manpower, which is why we will build the mine in a place with relatively low electricity charges. The payback cycle of a bitcoin miner is related to many factors, such as policy, technology, currency price, computing power, maintenance status and so on. It generally takes 200-300 days to payback. But as the market fluctuates, so does the cycle

with the mine, let's talk about the mine pool. As more and more people are now engaged in mining, more and more mining machines and mines are added, and the total power is growing. In this case, the probability of a single miner digging into bitcoin is getting smaller and smaller. So, people came up with a way. Since mining machines can't do it alone, we can combine mining machines to compete with other mining machines in the world - the collection of computing power of mining machines is the so-called mine pool. In this way, the probability of mining can be greatly increased. When bitcoin is g, corresponding rewards will be given to each miner according to its contribution to the total computing power

the concept of mine pool is more abstract than mine field. The ore pool can be a collection of several mining machines, or a collection of computing forces of mining machines in a number of mines. For example, when it comes to a mining pool in China, the mining machines connected to the pool include both Chinese and foreign mining machines, which are distributed according to work regardless of region.

MPOs is a new payment proct, which connects with mobile phones, tablet computers and other general intelligent mobile devices, transmits information through the Internet, and completes card reading, pin input, data encryption and decryption, prompt information display and other operations by external devices, so as to realize the application of payment function

< H2 > extended materials:

the definition of MPOs includes two parts: terminal equipment and related applications. The merchant's cashier operation is carried out through the mobile communication device (including the carried payment application software), the external special acceptance terminal completes the collection and encryption of UnionPay card related information, and the transaction is completed through the interaction between the mobile communication device and the background processing system

6. Is a small POS, indivials can deal with, do not need a large POS business license, store and other documents, deal with simple and fast. I use xingyifu. It's OK. During the period, I changed the other two. If something goes wrong, xingyifu will call and someone will take care of you
