Large-scale project management system and method based on blockchain technology

Abstract

The invention discloses a large-scale project management system based on the blockchain technology. A central node, stakeholder nodes, a key module, an information retrieval module and a block structure module form an integrated body; the central node is a planning department node, the stakeholder nodes are a R&D department node, an expert group node, a finance department node, a construction unitnode and a device unit node; the central node and the stakeholder nodes are connected through the P2P network. The system is advantaged in that the stakeholder nodes of the enterprise large-scale project and the project implementation flow are interconnected through the blockchain technology, and stakeholders are made to participate effectively in large-scale project management; data generated during project implementation are stored in the multiple nodes, and data availability is improved; blockchain reading and writing permissions are effectively allocated, and data security and non-repudiation are improved; the contract dispute risk and transaction cost are reduced, and transaction automation is promoted.

Description

technical field [0001] The present invention relates to the field of project management and computer application technology, specifically a large-scale project management system and method based on block chain technology. Background technique [0002] In traditional large-scale project management, all stakeholders have their own business processes and business data, which are stored in databases operated by all parties. This will have the following problems: [0003] 1. The data is not highly available, that is, it is very dangerous for the data to exist in one place. When the node's own database is damaged, the data will be lost; [0004] 2. Single-point control, that is, there is only one writing point, and the work efficiency is low; [0005] 3. Poor linkage ability, that is, when stakeholders need to exchange data, they need to take out their own data for statistics and reports, and then carry out data interaction after the consent of the respective node leaders, the p...

AI Technical Summary

Problems solved by technology

[0003] 1. The data is not highly available, that is, it is very dangerous for the data to exist in one place. When the node's own database is damaged, the data will be lost;

[0004] 2. Single-point control, that is, there is only one writing point, and the work efficiency is low;

[0005] 3. Poor linkage ability, that is, when stakeholders need to exchange data, they need to take out their own data for statistics and reports, and then carry out data interaction after the consent of the respective node leaders, the process cycle is long and the transparency is poor;

[0006] 4. Data inconsistency, that is, in the process of project implementation, the data generated by all stakeholders are stored in their own databases, which is prone to data inconsistency;

[0007] 5. The data security is poor, that is, the stakeholders randomly change the parameters, amount, progress, etc. according to the principle of maximizing their own interests, which leads to a crisis of trust among the stakeholders

[0008] The above problems will seriously affect the progress of large-scale projects and the interests of various stakeholders, making large-scale project management deadlocked
