Each node produces all second candidate cryptographic Hash (HASH2 more than one) of reception and respective node in block chain
First candidate's cryptographic Hash (HASH1) carry out size comparison (also including the comparison between HASH2), select wherein minimum Hash
Value, i.e. target cryptographic Hash.
Minimum candidate's cryptographic Hash is defined as target cryptographic Hash by the present embodiment, because size judges easily to realize, meter
Calculation amount is little, and the present embodiment is easier to realize, meanwhile, the present embodiment specify that target cryptographic Hash is established rules then really, further determine that
The accounting nodes of block to be accessed.
In the present embodiment, the accounting nodes based on last position block determine the transaction data of block to be accessed, composition data
Bag, because what the accounting nodes of last position block were to determine, the transaction data of the block to be accessed has necessarily unique
Property and certainty, and then cause block to be accessed uniquely determine, be easy to the smooth establishment of the block to be accessed；
Respective node data is based on by each node in block chain network and the packet carries out Hash operation and obtains candidate
Cryptographic Hash (first candidate's cryptographic Hash and second candidate's cryptographic Hash), because the irreversible feature of hash algorithm, it is ensured that candidate
Cryptographic Hash is completely unidirectional unpredictable, though accounting nodes of the packet based on last position block and determine, the note of the last position block
Therefore account node can not also adjust the node data of oneself and cause the candidate's cryptographic Hash of oneself to turn into target Hash with cheating mode
Value, thus the possibility that the accounting nodes for eliminating last position block are done evil, meanwhile, candidate's cryptographic Hash is completely unidirectional unpredictable, can
The randomness of candidate's cryptographic Hash is further enhanced, that is, ensures that the accounting nodes of block to be accessed randomly generate so that block
Each node is not temporary in weak position in competition book keeping operation because calculating the other factors such as power or rights and interests in chain, ensures each in block chain
