A transaction realization system and method based on Java smart contract service logic

Abstract

The invention discloses a transaction implementation system and method based on Java smart contract service logic. The system comprises a basic class module, a basic function method module and a calling module. And the calling module depends on the other two modules, and finally exposes a specified method to the Java intelligent contract engine end for execution through free combination of a plurality of basic methods in the basic method module. The user-defined intelligent contract depends on a basic intelligent contract framework provided by an engine; each module is realized according to arule in a framework; and finally, the engine generates a user-defined intelligent contract according to the basic contract template and the user-defined intelligent contract. A built-in variable is set for an intelligent contract of a user, a corresponding life cycle method is called, an appointed method in a calling module is called, the whole process is completed in contract calling once, and the transactionality of the whole process is guaranteed through inherent transactionality of one transaction in a block chain network. The problem that the transactionality of one business process is difficult to guarantee due to the fact that a traditional complex business process involves multiple contract calls is solved.

Description

technical field [0001] The invention relates to the field of blockchain smart contracts, in particular to a transaction realization system and method based on Java smart contract business logic. Background technique [0002] Blockchain is a new type of decentralized protocol, which can safely store digital currency transactions or other data, and the information cannot be forged and tampered with; smart contract is a piece of code that can be deployed and executed in the blockchain network environment. The deployment and execution of a segment of code can be presented in the form of transactions in the blockchain network, and its deployment and execution results can be consensused by the entire network along with the transaction; currently, the languages ​​supported by smart contracts include Solidity, Java, etc., smart Contracts are also widely used in various business applications based on blockchain. [0003] Most of the smart contract execution engines of alliance block...

AI Technical Summary

Problems solved by technology

But in the actual business logic, a complete actual business process may involve business logic methods of multiple application layers, which are mapped to the smart contract level, and are calls of multiple contract methods. These method calls are difficult to be executed as a transaction , once it fails, it is difficult to fully roll back

If the combination of business processes is provided in the smart contract in a hard-coded manner, it lacks flexibility and scalability
