METHOD, APPARATUS AND ELECTRONIC DEVICE FOR BLOCKCHAIN-BASED ASSET ISSUANCE

摘要

A node device in a blockchain receives an asset issuance transaction sent by an asset issuer, wherein the asset issuance transaction comprises a commitment value and a proof for performing a zero-knowledge proof with respect to the commitment value, and wherein the commitment value is calculated by inputting at least an asset type of a target asset object issued by the asset issuer as input data to a commitment function. The zero-knowledge proof with respect to the commitment value based on the proof is initiated. Whether the asset type of the target asset object is a legal asset type allowed to be issued by the asset issuer is verified. If the verification result is YES, the commitment value is issued to the blockchain for storage.
