BLOCKCHAIN-BASED TRANSACTION DATA OBFUSCATION METHOD, AND RELATED DEVICE

摘要

Disclosed is a blockchain-based transaction data obfuscation method. The method comprises: receiving an obfuscation request sent by a supplier node device for a target confidential transaction; obfuscating the target confidential transaction by using a target random number to obtain an obfuscated transaction; acquiring a random mapping parameter and a signed first challenge parameter from a regulator node device; performing product proving and power proving; and outputting the obfuscated transaction, a product proving result and a power proving result. Further provided is a related device. According to the present invention, anonymity of a transaction can be realized, and regulation of transaction data can also be realized.
