What does virtual currency POW mean

1.

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. POW: full name of proof of work

What does this mean? That is to say, how much money you get depends on the effective work you contribute to mining. In other words, the better the performance of your computer, the more money you will be allocated. This is to allocate money according to your work certificate. Most virtual currencies, such as bitcoin, Leyte and Ruitai, are based on the pow mode (the higher the computing power and the longer the mining time, the more money you get)

pos: proof of stake

What does that mean? In short, it is a system to pay you interest according to the amount and time of currency you hold. In the POS mode of certificate of equity, there is a term called currency age. Each currency has one currency age every day. For example, if you hold 100 currencies for 30 days, then your currency age is 3000. At this time, if you find a POS block, Your currency age will be cleared to 0. Every time you are cleared 365 coins, you will get interest of 0.05 coins from the block (which can be understood as 5% annual interest rate). In this case, interest = 3000 * 5% / 365 = 0.41 coins, which is very interesting. Holding coins has interest, very good!

3. What is BACC from mining

4. Due to the emergence of professional mining machines, it is basically impossible to use computers to dig bitcoin, and it is almost the same to dig some counterfeit coins. However, the emergence of LTC miner of Leyte coin has actually announced that it is impossible to prevent miner of all POW algorithm currencies. As long as a certain kind of currency is popularized, its miner will appear accordingly. It is suggested that you can take a look at diandianbi (the originator of POS algorithm), the algorithm that can really prevent mining machine.

5. I have heard a friend who has been mining for three or four years mention that the team members of Bateman information technology company are specialized in the research, development, manufacturing and sales of virtual currency mining equipment. It is said that they initially made traditional POW mining machines, and then graally turned to hard disk mining machines with the development of the instry. They have rich technology and experience, and the procts launched today are also very good.

6. Probability problem, but I suggest you don't pay first, see clearly. In addition, more observation of that friend's life and your relationship, true or false in such a little information is impossible to judge

7. First of all, you can register a company in Hong Kong of any nationality. Secondly, most of them are not registered in Hong Kong. For example, the famous Biyuan chain, quantum chain, Ethereum and fire coin network are not registered in Hong Kong, most of them are in Singapore. It's also registered in Switzerland
it's very easy to register a Hong Kong company. You only need to provide your ID card and company name. The registration time is 10 to 15 working days. It's very fast.
