Technical challenges in applying zero-knowledge proof to blockchain

Abstract

Blockchain is a peer-to-peer distributed ledger technology based on cryptography,However,open and transparent blockchain ledger,combined with sociological mining,data mining and other statistical methods,brings a major threat to user’s privacy.Therefore,privacy protection becomes a hot issue on the blockchain technology research.The existing privacy protection schemes were summarized,especially focusing on the zero-knowledge proof techniques.The technical challenges in applying zero-knowledge proof to blockchain privacy protection schemes were expounded and analyzed,and position solutions to these challenges were given.
