ZERO-KNOWLEDGE PROOF METHOD SUITABLE FOR BLOCK CHAIN PRIVACY PROTECTION, AND MEDIUM

摘要

Disclosed are a zero-knowledge proof method suitable for block chain privacy protection, and a medium, capable of supporting a Bitcoin UTXO and an Ethereum balance model and well combining with a smart contract, so that the security of the solution is further enhanced, the application scene of the solution is extended, and the zero-knowledge proof designed for a specific algebraic structure of a transaction, even a light node can also generate the process of proof. The technical solution is as follows: the method comprises: an initialization phase: generating a system parameter, including a generation process and meaning of the parameter; a proof generation phase: a specific process of generating a zero-knowledge proof, including a ciphertext generated in the process, involved formulas and parameters, etc.; and a verification phase: including a verification formula and conditions, etc.
