Building engineering cost supervision system and method based on block chain

Abstract

The invention discloses a building engineering cost supervision system and method based on a block chain. The system comprises a user management module, an investment decision module, a design controlmodule, a building design module, an engineering implementation module, a supervision auditing module and a distributed file system. The invention aims to solve the problem that an existing project cost management system is insufficient in transparency. A solution is provided for solving the problems of counterfeiting and easy tampering; the information of each link of the project cost is recorded and tracked through the block chain; a public, transparent, high-credibility and traceable distributed network is constructed by using a block chain technology, so that an auditable constructional engineering cost supervision system which cooperates and mutually supervises from multiple parties including a building general contractor, a consultation service company, a survey designer, a construction party, a supervisor and the like is realized; due to the characteristics of the blockchain system, the data is prevented from being tampered, the information transparency of the system is improved, and illegal operation of illegal users is prevented.

Description

technical field [0001] The present invention relates to blockchain-based information sharing, certificate storage and traceability, and cost management in the field of construction engineering, and in particular to a blockchain-based construction engineering cost supervision system and method. Background technique [0002] Blockchain technology, blockchain refers to a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. Blockchain can be divided into public chain, private chain and consortium chain, among which consortium chain technology is only for members of a certain group and limited third parties, allowing authorized nodes to join the network and view information according to authority. The transaction confirmation on the blockchain is completed by the consensus of all nodes on the blockchain, and after the consensus is successful, it is packaged and written into the block. Any behavior that wants to modify th...
