Enough normally to go out block, remaining miner can make view update, stop failure or the common recognition right for the miner that does evil.Therefore, in some realities
It applying in example, miner knows together during verifying block data, when detecting that the number of common recognition authentication failed is greater than preset threshold,
The common recognition server zone of miner's composition determines that malice miner, malice miner are not sign verifying block data and common recognition is caused to be verified
The most node of the frequency of failure.The common recognition server zone of miner's composition forbids malice miner to participate in common recognition verifying, and remaining
Miner, which redistributes share and knows together, verifies block data, for example, the miner A that accounting is 10% does evil, then, common recognition is taken first
Business device group stops the ballot right of miner A, secondly, common recognition server distributes to the accounting 10% of miner A according to preset rules
Remaining miner, for example, giving remaining miner, alternatively, distributing to remaining node according to the work age of miner, the work age is got over
Long, distribution accounting is higher, and the work age is shorter, and distribution accounting is lower.
Again, common recognition server zone continues common recognition and tests when the number for detecting common recognition authentication failed is less than preset threshold
