RHY mine mining knowledge: If multiple miners dug out the block at the same time, is the effective block?

2019-02-18 18:12

Mining, as the name suggests, is that the whole network miners solve the math problems through calculations to obtain the unique billing rights. There is only one node for accounting, that is, block reward, but there are miners asking a question. In tens of thousands of blocks, is it possible for multiple miners to dig up new blocks at the same time?

Everything in the world has its own contingency. It is possible for many miners to dig up new blocks at the same time but the probability is minimal. However, if there are multiple miners who dig out new blocks at the same time, who should be awarded the bonus? What is the trade-off standard? In this regard, the RHY mine answers this question for all new and old miners.

After the miner has dug out the block, the new block will be released as soon as possible. After the new block is verified by other miners (in accordance with the rules of the Bitcoin system), the block will be accepted and started on the basis of the block. Dig a block. After the sixth block, this block is finalized and permanently recorded on the chain.

Which is a valid block?

We assume that two miners A and B simultaneously dig out the Nth block, at which point the blockchain forms a short split, and assumes that the miner's chain is called the A chain, and the miner B excavates the chain. B chain. Miners A and B will broadcast the blocks they have dug. Other miners may receive new blocks from A miners, or they may receive blocks from B miners, and they will receive them separately. The blockchain is extended after the new block.

Assume that the miners on the A chain first dig out the N+1th block. At this time, the block excavator will broadcast the information of the N+1 block to the whole network, and other miners will detect the new legal zone. When the block is dug out, it will stop continuing to dig the N+1th block (whether it was dug in the A chain or digging in the B chain), it will choose to dig a (N+2) zone on the chain. Block, which means that the A chain wins, and the block of the Nth block is awarded to Miners A. (Strictly speaking, Miner B also gets the block reward, but because the miner B excavated the block is not the longest In the chain, it becomes a lone block and is not recognized. Therefore, the block reward will be invalid.)

Conversely, if the N+1th block is first dug out on the B chain, then all miners will continue to dig a block on the B chain, and the N block will be awarded to Miners B.

Longest legal chain

Why is this so? Because the Bitcoin system stipulates that only the longest chain is the legal chain, this is the consensus of all miners, so when a legal new block is dug out, all miners will dig a section on the basis of this block. Block, because this is the most economical and profit-maximizing choice for all miners, and the other chain will be abandoned by the miners, and the blocks on the abandoned chain are also called lone blocks.

If in the N+1th block, the A chain and the B chain appear again at the same time (the probability of this case is very small), the two chains will continue to compete until a chain first digs up a new block. Other miners choose the longest legal chain to continue mining and discard another chain.

Blocks that have been abandoned by the chain are also legal before the winners and losers. There are also bonuses. After determining that a chain is the longest legal chain, the other chain becomes abandoning the chain. The rewards on the abandoned chain will not be recognized.

To sum up, if a block is high, many miners will dig out the block at the same time. At this moment, the blocks they dug out are legal, and the blockchain will be temporarily forked. All the miners are in themselves. The first block to be monitored continues to dig a block until one party first digs out the legal new block. All miners will mine on the longer legal chain. This is the longest legal chain mechanism of Bitcoin. Block rewards will give miners who are on the longest legal chain. The other chain will be abandoned and the system rewards obtained on the abandoned chain will not be recognized.

Therefore, the sooner the miners dig out new blocks, the sooner they will release the miners. In this regard, the miners are inclined to concentrate mining in the mine, and unified in a mining pool, RHY mine in the overseas mines mining electricity charges after the Spring Festival is as low as 0.18 yuan per degree, to meet the majority of miners for low-cost digging The demand for mines, limited time activity electricity prices have attracted a large number of miners to enter the market. After all, mining still depends on low electricity bills. When the currency price is high, it is also when the currency price is low.
