摘要
Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for blockchain-based payment withholding and agreement signing are described. In one computer-implemented method, an agreement signing transaction submitted by a user is received and used to authorize a payment system to provide a payment withholding service for a payment order of the user in a third-party service system. The agreement signing transaction includes agreement signing information of a tripartite agreement submitted by the user. Withholding verification logic declared in a first smart contract published on the blockchain is invoked to check whether there is a withholding agreement signed between the payment system and the third-party service system on the blockchain. If yes, the tripartite agreement is created that authorizes the payment system to provide the payment withholding service for the payment order for the user and published to the blockchain for certificate storage.
