Abstract
A blockchain-based trusted setup method for zero-knowledge proof (ZKP), performed by a specific node of a blockchain network, may comprise: transmitting a first hash value of a first common reference string (CRS) to a first node; receiving a second hash value of a second CRS from the first node; transmitting the second hash value to a second node; and receiving a third hash value of a third CRS from the second node, wherein the second CRS is generated by the first node encrypting or hiding the first CRS acquired from a public storage through a CRS update module using a secret key of the first node, and the third CRS is generated by the second node using the second CRS acquired from the public storage and a secret key of the second node.
