Abstract
The rapid development of the Internet has driven the network technology to all walks of life, and the generation of massive data flow has caused huge pressure on the traditional centralized data management platform. The data information management system built can provide a better solution for data control nowadays. To this end, this paper researches the consensus algorithm to make the nodes of blockchain network reach consistency, addresses the lack of node behavior control problem of practical Byzantine fault tolerance (PBFT) algorithm, quantitatively evaluates the node reputation by combining the custom reputation model with PBFT algorithm, optimizes the selection of master nodes in the consensus process, and completes the real-time update and full monitoring of node reputation, which is essential for It has a good role in improving the security and reliability of blockchain system consensus. The scheme has certain theoretical and practical significance to solve the problem of safe storage of data in the market and improve the governance system of data.
