Abstract

The invention provides a power settlement privacy protection method and device. The method comprises the following steps of: acquiring settlement information of participants in a settlement period; performing power settlement according to a settlement information chain to obtain a plurality of pieces of settlement data; generating a state change zero knowledge proof by using zkRollup, aggregating the plurality of pieces of settlement data, and chaining non-sensitive settlement data and the state change zero knowledge proof, so as to enable other nodes on the settlement chain to verify the state change zero knowledge proof to obtain a state variable of a global participant; and generating and chaining an SNARK zero knowledge proof by using a sensitive field, so as to enable other nodes on the settlement chain to verify the change data of the corresponding participants based on the SNARK zero knowledge proof, and after the participants pass verification, verifying the effective change data of each participant on the chain based on the state change zero knowledge proof. By applying the method, the performance of a power settlement transaction system is improved, and the purpose of privacy protection is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power settlement, in particular to a method and device for protecting privacy of electric power settlement.
