and when the hash values are different, the fact that the consumption voucher information or the transaction information in the renewable energy consumption responsibility weight system is tampered is proved. At this time, the tampered transaction information in the main database needs to be replaced by the transaction information in the sub-database, secondary hash calculation is performed, comparison is performed with the hash value on the link, and if the result is the same, tampering correction is completed. And performing hash operation of the next transaction until all transaction information is calculated, and completing the tracing of the renewable energy power consumption voucher.
Taking fig. 3 as an example, when the hash value (0,1) is the same as the hash value on the corresponding chain, and the hash value (0,1,2) is different from the hash value on the chain, it is proved that the credential transfer transaction information of the 2 nd time is falsified. At the moment, the renewable energy consumption responsibility weighting system replaces the 2 nd voucher transfer transaction information in the main database with the 2 nd voucher transfer transaction information in the sub-database, performs secondary hash calculation to obtain hash values (0,1 and 2), compares the hash values with the hash values on the chain, and finishes tampering correction if the results are the same.
