Methods and apparatuses for processing service using blockchain

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• providing, by an association center to an event party, an event model identifier for an event model by allocating the event model identifier to the event model in response to determining that the event party selects no event model from an event model list sent by the association center, wherein the event model identifier indicates the event model for describing an event;
• receiving, by the association center, the event model identifier and data of the event, wherein the data comprises one or more parameters in the event model;
• determining, by the association center, a contract identifier associated with the event model identifier based on a predetermined relationship between the event model identifier and the contract identifier;
• identifying, by the association center, a smart contract in a blockchain network based on the contract identifier;
• and
• sending, by the association center, a request that invokes the smart contract to a first node in the blockchain network based on the contract identifier and that causes each node in the blockchain network to invoke the smart contract based on the data to perform service processing logic corresponding to the smart contract.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• providing, by an association center to an event party, an event model identifier for an event model by allocating the event model identifier to the event model in response to determining that the event party selects no event model from an event model list sent by the association center, wherein the event model identifier indicates the event model for describing an event;
• receiving, by the association center, the event model identifier and data of the event, wherein the data comprises one or more parameters in the event model;
• determining, by the association center, a contract identifier associated with the event model identifier based on a predetermined relationship between the event model identifier and the contract identifier;
• identifying, by the association center, a smart contract in a blockchain network based on the contract identifier;
• and
• sending, by the association center, a request that invokes the smart contract to a first node in the blockchain network based on the contract identifier and that causes each node in the blockchain network to invoke the smart contract based on the data to perform service processing logic corresponding to the smart contract.
