Method and apparatus for consensus verification

Abstract:

A method for consensus verification implementable by a first blockchain node in a consensus network may comprise: receiving a transaction request from a client, and performing a first security verification on the transaction request; in response to determining that the transaction request passes the first security verification, storing the transaction request, and broadcasting the transaction request to each of second blockchain nodes in the consensus network, causing the each second blockchain node to store the transaction request in response to the second blockchain node determining that the transaction request passes a second security verification; performing pre-processing on at least one stored transaction request in response to determining that a preset condition is satisfied, to obtain and store a pre-processed block; and broadcasting the obtained pre-processed block to the second blockchain nodes, causing the second blockchain nodes to perform consensus verification on the obtained pre-processed block.
