DHBFT: Dynamic Hierarchical Byzantine Fault Tolerant Consensus Mechanism Based on Credit
It is significant to improve Practical Byzantine Fault Tolerance algorithm (PBFT) in consortium blockchain. At present, the serial verification process of transactions in the primary and backups greatly affects consensus efficiency. Meanwhile, the lack of reasonable valuation mechanism in PBFT makes it difficult to motivate existing reliable nodes. Moreover, consensus nodes work in an enclosed environment, where nodes cannot join and exit dynamically.
