wholesale agate slices for jewelry What does the computing power in POC mining mean?

wholesale christian jewelry store The essence of POC can also be understood by an ordinary person, that is, mining with hard disks. That's right, POW uses a CPU (or graphics card, ASIC mining machine, and their essence is a stronger computing chip, which is the same as the CPU) mining. POS is mining by holding currency ratio. Determine the super node, and POC is mining by hard disk.
We can understand this:
-The chip computing of whose chip in POW is easy to dig at the mine;
-who holds more coins in POS, who can easily dig to dig it to Mining;
-who has obtained more votes in DPOS can become a super node for mining;
-who is a large hard disk capacity in the POC, who is easy to dig to the mine.
Is it easy to understand enough!
It to understand the specific principles of POC, we still have to start with Bitcoin POW (study blockchain, POW is the technical concept you can never go through).
Pow's full name is Proof of Work, that is, the workload proof. The so -called workload here is the miner's CPU (or graphics card, ASIC chip. We have already said earlier that these hardware only calculates faster, the essence is not different from the CPU) to perform a calculation work called hash algorithm. In short, who can perform more hash computing within a unit time, who has a greater chance to generate a haveh result that meets the requirements and then get the right to write to the blockchain.
This can be said that the essence of Bitcoin POW is to compete for mining. The emergence of each new block is to give the miners a "problem". Miners compete through computing power to compete who can find the "answer" that meets the requirements first. Miners can obtain a stronger computing power proportion by buying a Niubi computing chip and continuous consumption of power energy for high -frequency and high intensity, and then obtain the probability of finding the "answer" greater. If a Bitcoin miner has 20%of the computing power on the entire network, in theory, he can dig out 20%of new blocks and get 20%of block rewards (the earliest blocks each have 50 Bitcoin rewards, and now it has decreased. By 12.5, it will continue to be halved next year).
POW mining rules are simple and rude, and the computing power can be freely entered and exited, so it can establish sufficient security to ensure the characteristics of the blockchain that is not tampered with. This is why Bitcoin seems to be simple, but it can become the king of coins, occupying about half of the market value.
Ip, Bitcoin's fork coins (such as BCH and BSV), Litecoin LTC, Ethereum ETH, Monroe Monero, and Dash DASH are also all or partially using the POW mechanism mining coin The species may be different from Bitcoin in some technical parameters, but the overall thinking is similar.
The protagonist POC today is the same as Bitcoin POW, but there are some substantial differences. We know that Bitcoin POW requires miners to continue and repeatedly execute hash computing. Miners need to run their computing chips with high intensity and consume extremely considerable power resources.
. Our POC has opened a very clever road: it requires miners to calculate the huge number of hash in advance and store these data in the hard disk; when mining, the miners are also scrambling to crack down "Difficulty", the difference is that the answer to the "problem" should be found in the hard disk data, not in real time. Naturally, who has a greater capacity of the hard disk, who can store more "alternative answers" in advance, has a higher probability to find the "correct answer" that can match the "problem".
Mature may be asked. In the POC mechanism, is it likely that the miner is likely to calculate the answer to cheat through the chip? impossible. POC's algorithm design determines that when it is looking for "answers, it is very sensitive to the element of storage space, and it is not so sensitive to the computing power of the chip. The powerful computing power is not great to the permanent power bonus of miners' mining, and it has more storage space to improve the power of mining. This characteristic of POC is also vividly referred to as "space change time".
