Construction and Application Research of Safe Building Information Sharing System Based on Blockchain Technology

Abstract

In recent years, blockchain, as one of the emerging information technologies, has been increasingly integrated into the whole process of development in various economic and social fields and industries, playing an important role in global resource reorganization, global economic structure reshaping and global competition pattern change. This paper proposes a hybrid chain model combining DPoS-Quorum consensus algorithm for coalition chains and PANDA consensus algorithm for public chains in conjunction with the current situation of construction supply chain, and experiments prove that this paper's method, while ensuring data security and privacy security, can accelerate the data circulation and sharing efficiency of construction supply chain.
