Abstract

Blockchain is being pursued by a growing number of people with its characteristics of openness, transparency, and decentralization. At the same time, how to secure privacy protection in such an open and transparent ledger is an urgent issue to be solved for deep study. Therefore, this paper proposes a protocol based on Secure multi-party computation, which can merge and sign different transaction messages under the anonymous condition by using Pedersen commitment and Schnorr Signature. Through the rationality proof and security analysis, this paper demonstrates the private transaction is safe under the semi-honest model. And its computational cost is less than the equivalent multi-signature model. The research has made some innovative contributions to the privacy computing theory.
