ZERO-KNOWLEDGE PROOF SYSTEM FOR PRIVACY PROTECTION IN BLOCKCHAIN ORACLE AND METHOD FOR SAME

摘要

The present invention relates to a zero-knowledge proof system for privacy protection in a blockchain oracle and a method for the same. The zero-knowledge proof system comprises: a TLS server providing data; an oracle TLS client performing the function of requesting off-chain data and transporting the same to the blockchain; a verification contract performing the function of verifying a presented proof; and a TLS certchain performing the function of an authentication certificate of a website including the TLS server, wherein the TLS server and the TLS client establish a session through a handshake process, record in a record unit during a TLS communication process, and compare record sets to each other upon termination of a TLS session, and if the record sets are identical as a result of comparison, generate C_n including random r with respect to a record corresponding to personal information.;COPYRIGHT KIPO 2020
