Electric power system material contract management system based on block chain

Abstract

The invention provides an electric power system material contract management system based on a block chain, and the system comprises: a block chain bottom platform, wherein the block chain bottom platform is used for database maintenance, account book maintenance and intelligent contract management, guarantees that data is not tampered, and provides a registration function and a logout function through CA; an intelligent contract, wherein the intelligent contract comprises seal management, user information management, signature management and contract management, and is used for calling a transaction interface; a service layer, wherein the service layer is used for providing a RESTful interface for Web service, processing a service request, converting service interfaces of seal management,signature management and contract management into the RESTful interface, and then accessing an SDK sub-packaging RESTful interface; and an application layer, wherein the application layer has the functions of user login, user logout, seal adding, signature adding, contract initiating, contract signing, contract refusing and contract downloading. Contract signing efficiency is improved, and progress and quality of power grid construction engineering are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain-based power system material contract management system. Background technique [0002] Electronic contracts are supply agreements and agreements signed between power companies and suppliers. Since the equipment required for power grid construction is quantitatively produced according to the required scenarios and technical indicators, it is necessary to manage material procurement contracts in the early stage of the project to formulate procurement tasks. Contract management determines the type, quantity, cost, technical content and delivery / inspection method of purchased materials, so the signing of the contract directly affects the supply of power equipment and has a great impact on the progress of power grid construction projects. [0003] Most of the material contracts used in the power industry are paper contracts, and a small number of contract...

AI Technical Summary

Problems solved by technology

[0004] Electronic contracts use cryptographic algorithms in the process of signing contracts to solve the problem of insufficient security in the signing process of traditional paper contracts, but because they store contracts in electronic form, there are security risks in data storage. In terms of storage methods, centralized servers are mostly used for centralized storage, and storage device failures and hacker attacks are likely to cause loss and tampering of contract data; secondly, in terms of verification methods, verification methods are generally not used or verified by a third-party authority, which is safe Poor reliability and low efficiency; finally, in the traceability method, the evidence is single and difficult to trace, and once there is a problem with the contract, the convincing power is weak
