With the rapid development of e-commerce systems, centralized service model gradually fails to meet needs SMEs. In existing system, users’ transaction data and reputation scores are stored in a cloud server, which has high storage cost, low processing efficiency, is vulnerable attacks leaks.

The combination of blockchain technology and supply chain meets the needs effective management transparency information, promotes development all walks life. However, Practical Byzantine Fault Tolerant algorithm (PBFT) is not suitable for large-scale due to its poor scalability, arbitrary selection master nodes simple grouping. To solve this problem, paper proposes a Re-PBFT (Reputation-PBFT, Re-PBFT) based on reputation-value assessment group. Firstly, reputation value node evaluated...
