Summary:The present invention relates to a signature and verification technology for protecting personal information included in a transaction on a blockchain platform. The present invention includes: an authentication module generating a first certificate; a node which generates a second certificate which the personal information is omitted from and zero-knowledge is applied to and a transaction including the second certificate using the first certificate generated by the authentication module; and a verification module which verifies the transaction generated by the node. Therefore, system bottleneck of the authentication module is resolved, and efficient network configuration is possible. 본 발명은 블록체인 플랫폼에서 트랜잭션에 포함된 개인정보를 보호하기 위한 서명 및 검증 기술로서, 제1증명서를 생성하는 인증모듈, 인증모듈에서 생성된 제1증명서를 이용하여 개인정보가 생략되며 영지식(Zero-Knowledge)이 적용된 제2증명서 및 제2증명서가 포함된 트랜잭션을 생성하는 노드, 노드에서 생성된 트랜잭션을 검증하는 검증모듈을 포함한다.
