Research and Implementation of Blockchain Warehouse Receipt Trading Platform Based on BFT

摘要

For the problems of excessive centralization in information flowing, low performance in business extension, and being difficult to guard against the risk of the bill market in the traditional warehouse receipt trading system, this paper proposes a warehouse receipt trading platform based on block chain technology. By introducing the BFT (Byzantine Fault Tolerance) mechanism into block chain technology, the platform implements a distributed consensus algorithm based on the improved BFT algorithm. Other technologies such as smart contract of Ethereal are used to optimize the algorithm. Compared with the traditional centralized system, the platform has the characteristics of decentralization, distributed consensus, trustworthiness, traceability, irreversibility, and fault tolerance. The experimental result shows that the consensus efficiency of the platform has obvious advantages compared with current block chain systems like Bitcoin and Ethereal.
