A large-scale project management system and method based on block chain technology

Abstract

The invention discloses a large-scale project management system based on blockchain technology, which includes a central node, a stakeholder node, a key module, an information retrieval module and a block structure module to form a whole; the central node is a planning department node , the stakeholder nodes are R&D department nodes, expert group nodes, finance department nodes, construction unit nodes, and equipment unit nodes; the central node and stakeholder nodes are connected together through a P2P network. The present invention interconnects the stakeholder nodes and project implementation process of large-scale projects of enterprises through blockchain technology, so that stakeholders can effectively participate in the management of large-scale projects; the data generated during the project implementation process is stored in multiple nodes, Improve the availability of data; effectively allocate the read and write permissions of the blockchain, improve data security and non-repudiation; reduce the risk of contract disputes and transaction costs, and promote transaction automation.

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
