一种监管友好的可编辑区块链方案OA北大核心CSTPCD

Existing blockchain content supervision schemes adopt ex-post governance methods,lack of pre-audit,and have problems of signature invalidity and low efficiency of multi-version block verification.To address these problems,firstly,this pa-per designed a dynamically adjustable and accountable data audit method to realize prior audit of blockchain transaction data.Secondly,it designed a redaction-controlled digital signature scheme to solve the problem of signature invalidity caused by edi-ting operations.Finally,it designed a blockchain data consistency verification protocol to achieve efficient verification of query results.The results of security analysis and performance testing demonstrate the security and effectiveness of the scheme.In the case of controllable supervision,the scheme still maintains high efficiency in block generation and verification,and it provides a new solution for blockchain content supervision.
