Blockchain intelligent contract generation and management system and implementation mechanism thereof

Abstract

The invention provides a blockchain intelligent contract generation and management system. The blockchain intelligent contract generation and management system comprises an off-chain intelligent contract design and development module, an automatic deployment module and an on-chain intelligent contract management module, the off-chain intelligent contract design and development module is divided into an off-chain intelligent contract design sub-module and an off-chain intelligent contract development sub-module, the off-chain intelligent contract design sub-module supports a user to create an intelligent contract in a visual dragging mode according to the flexible design model, and two types of files are outputted respectively; the off-chain intelligent contract development sub-module usesa flexible design model to divide a contract into an index contract, a data contract and a logic contract by taking plug-ins as units and taking each plug-in as a plug-in contract on the basis of thethought of data and logic separation; the automatic deployment module uses a method for deploying contracts in the generated. Go file to carry out contract automatic deployment and chaining; and the on-chain intelligent contract management module maintains the on-chain running intelligent contract. The invention also provides a corresponding implementation mechanism.

Description

Technical field[0001]The invention relates to the technical field of block chains, in particular to a block chain smart contract generation and management system and its implementation mechanism.Background technique[0002]Blockchain is a brand-new decentralized infrastructure that has the characteristics of openness, transparency, traceability, and non-tamperability. In recent years, blockchain technology has developed rapidly and has been highly valued by academia and industry. Blockchain has extended to many fields such as digital finance and the Internet of Things, and is an important part of the "new infrastructure". The concept of Smart Contract was first proposed by Nicholas Szabo in 1994. It is a computer transaction agreement that enforces the terms of the contract. For a long time, the development of smart contracts has been relatively slow and the scope of application is limited. With the advent of blockchain, smart contracts and blockchain have formed a natural alliance. T...

AI Technical Summary

Problems solved by technology

Since the problem of smart contracts has led to a number of security incident vulnerabilities, smart contracts have not yet formed a general model of software engineering, so efficient smart contract design models and easy-to-use development methods are urgently needed to be solved

[0005] (2) Smart contracts are "difficult to maintain"

Iterative updating of smart contracts deployed on the blockchain is a complex process

For example, a smart contract with complex logic and a lot of data needs to be upgraded for a specific logic. It needs to be re-deployed after changing the contract, and the data of the previous version needs to be migrated, which is time-consuming and laborious.

For some businesses that cannot be interrupted, this method is not feasible

[0006] (3) Smart contracts are "difficult to manage"

[0014] To sum up, the current smart contract design, management model and tools are still in the initial exploration stage, far less mature than traditional software engineering, and need more theoretical methods and tool support
