FIELD: information technology.
SUBSTANCE: invention relates to computer engineering and is intended for business verification. First node of the block chain of packets at least one business request, which is received from own memory for business operations, into a preprocessed block and broadcasts the preprocessed block to the second nodes of the block chain. When finding that memory for business operations corresponding to it does not include part of business request in preprocessed block, second block chain node may receive a portion of a business request from another block chain node and perform consensus verification for the preprocessed block by using a portion of the business request and a business request stored in its own storage for business operations. If the second unit of the block chain finds, after receiving the preprocessed block, that the memory for business operations corresponding to it does not include part of the business request in the preprocessed block, the second unit of the block chain does not directly consider the preprocessed block as faulty in consensus verification. Instead, the second unit of the block chain receives the missing business request from the other node of the block chain to perform consensus verification for the preprocessed block. Therefore, accuracy of business-processing of full business on the basis of block chains is effectively increased.
EFFECT: solving problem of low accuracy of business processing for business on the basis of block chains.
