Abstract
(EN)
The present invention relates to a signature and verification technology for protecting private information included in a transaction on a blockchain platform, the technology comprising: an authentication module for generating a first certificate; a node for generating a second certificate in which private information is omitted by using the first certificate generated in the authentication module and to which zero-knowledge is applied, and a transaction including the second certificate; and a verification module for verifying the transaction generated in the node.
