Node synchronization method, device and equipment of block chain and storage medium

Abstract

The invention relates to a block chain technology. The invention provides node synchronization method, device and equipment of a block chain and a storage medium. The method comprises the steps of selecting a main node from nodes in the same organization based on a preset election algorithm; and performing transaction processing on each to-be-verified transaction in the transaction block through the main node, and performing validity marking on each to-be-verified transaction based on a transaction processing result corresponding to the to-be-verified transaction, generating transaction information corresponding to each to-be-verified transaction, and sending the processed transaction information and the transaction block to the standby node, and enabling the standby node to perform transaction information synchronization based on the verification result of the main node, so that each organized node only needs to verify the transaction block once, the network flow of the block chain isgreatly reduced, the performance of the whole block chain network is improved, and computing resources are saved. The information can be stored in the block chain node. Most computing resources can be used for serving the query request, the query request throughput of the whole block chain network is improved, and the request delay is reduced.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain node synchronization method, device, equipment and computer-readable storage medium. Background technique [0002] Blockchain is generally understood as a distributed ledger, and its essence is a distributed database. One of the fundamental differences between the consortium blockchain and ordinary blockchains is the need to provide a privacy protection mechanism, which is generally implemented through signature encryption and signature verification and decryption in cryptography. Signature verification, that is, to verify the block signature, not only to verify the validity of all transaction signatures in the block, but also to verify whether the signature policy meets the current policy. Therefore, this step involves a large number of mathematical operations and takes a lot of time. Usually, multiple transactions are packaged into blocks and sent t...
