A distributed data compliance review method and system

Abstract

The present invention discloses a distributed data compliance review method and system, and relates to the field of data processing technology. The steps of the method include: deploying a unified compliance code for each node in the blockchain, and conducting a preliminary review of the transaction; electing an accounting node through a consensus algorithm, and conducting a compliance review through a deployed compliance verification algorithm; if the transaction is not compliant, the transaction data is directly discarded; if the transaction is compliant, the compliant transaction data and its verification process log are packaged into blocks and then Hash calculation is performed to generate a block Hash; the accounting node broadcasts the constructed block to other nodes in the network, and through the node mutual verification mechanism, determines whether to accept the block and continue to participate in the consensus process. The present invention prevents malicious nodes from doing evil and skipping compliance verification; at the same time, it helps to prevent some nodes from being overloaded due to excessive computing power, and improves the stability and reliability of the entire blockchain network.
