Project completion management system based on block chain and implementation method thereof

Abstract

The invention relates to a project completion management system based on a block chain and an implementation method thereof. The system comprises an open interface module, a plan management module, awork package management module, a document management module, a block chain network module, and a database. The open interface module is a channel for interaction between the system and an external application, and the external application accesses the system through the open interface module. A project owner, a contractor and a construction party digitally sign project plan information through the plan management module, and the digital signatures are stored in the block chain network module. The work package management module is used for dividing and assigning work packages to different construction parties, and updates of work package states are stored in the block chain network module. The document management module is used for saving and tracking design documents of system components,and after the design documents are performed by hash calculation, eigenvalues are sent to the block chain network module. The block chain network module adopts a trusted authorization access federation chain system, and is used for storing of a project plan, work package states and design document change information. The information is stored in the database. The system effectively shares projectcompletion information, records changes, and records a completion status.

Description

technical field [0001] The invention relates to a blockchain-based project completion management system and an implementation method thereof. Background technique [0002] At present, blockchain technology is being applied in more and more fields. In the field of engineering project management, blockchain technology can also have a wide range of application space. In the traditional project completion management process, there are many different participants, including project owners, contractors, construction parties, etc., and information asymmetry , The lag in sharing, the low credibility, and the long circulation cycle all lead to the inability of the participants to obtain correct information in a timely and effective manner during the completion of the project, lack of trust, and lead to delays in project settlement. Blockchain technology has the characteristics of decentralization and non-tampering. These characteristics are very suitable for multi-party participatio...
