A transaction implementation system and method based on java smart contract business logic

Abstract

The invention discloses a transaction realization system and method based on Java smart contract business logic, including a basic class module, a basic function method module and a calling module. The calling module depends on the other two modules. Through the free combination of multiple basic methods in the basic method module, a specified method is finally exposed to the Java smart contract engine for execution; user-defined smart contracts rely on the basic smart contract framework provided by the engine , each module is implemented according to the rules in the framework. Finally, the engine will set built-in variables for the user's smart contract according to the basic contract template and the user-defined smart contract, call the corresponding life cycle method, and call the specified method in the calling module , the entire process is completed in one contract call, and its transactionality is guaranteed by the inherent transactionality of a transaction in the blockchain network. To solve the problem that the transactional nature of a business process is difficult to guarantee due to the fact that traditional complex business processes involve multiple contract calls.

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
