Abstract
Implementations of the present specification describe a computer-implemented method, medium, and system. In one computer-implemented method, a contract creating request from a requesting user is received by a blockchain node of a blockchain network, where the contract creating request includes creation information of a target electronic contract to be created. A first smart contract is deployed for managing the target electronic contract in a blockchain based on the creation information. The target electronic contract is created according to the creation information and based on the first smart contract. In response to receiving a contract signing request from a signatory user of the target electronic contract, the target electronic contract is signed based on the first smart contract and a second smart contract corresponding to the signatory user, where the second smart contract is a pre-deployed smart contract for managing information associated with the signatory user.
