In the present embodiment, block chain node 1, block chain node 2, block chain node 3 are in the book keeping operation power to n-th block
When being grabbed, bonus that block chain node 1, block chain node 2, block chain node 3 have selected respective expection to obtain respectively
Volume, for example, the expected obtained amount of money award of block chain node 1 is MONEY-A, the expected obtained amount of money award of block chain node 2
For MONEY-B, the expected obtained amount of money award of block chain node 3 is MONEY-C.Block chain node 1 is calculated including MONEY-A

, respective private key is respectively adopted to the n-th block of each self-generating in block chain node 1, block chain node 2, block chain node 3
It is broadcast in block chain network with after the cryptographic Hash signature of the n-th block.If having exceeded preset time T IME-MAX, block
Chain node 1, block chain node 2, block chain node 3 stop calculating, at this point, comparing HASH-A, HASH-B, HASH-C respectively with the
The absolute value of the difference of the cryptographic Hash of N-1 block, if the absolute value of the difference of the cryptographic Hash of HASH-A and the N-1 block is most
It is small, it is determined that block chain node 1 obtains the book keeping operation power of the n-th block.
The embodiment of the present invention obtains the first cryptographic Hash of the N-1 block in block chain by block chain node, calculates institute
