Beh-Raft-Chain: A Behavior-Based Fast Blockchain Protocol for Complex Networks

By facilitating multiple independent owners to jointly control a distributed network, blockchain can be used solve the problem of device collaboration in complex networks (e.g., 5G, health care industries) through consensus mechanism. However, state-of-the-art blockchain-based solutions cannot meet demand high transaction rate for those applications, due unavoidable data synchronization cost decentralized systems. To address this issue, recent research splits nodes into groups as parallel shardings improve scalability at increased communication and storage per node. This paper proposes fast secure protocol reduce traffic complexity while enhancing rates capability fault-toleration. We introduce Proof-of-Behavior (PoB), behavior-based incentive mechanism, stimulating honest behavior neutralizing malicious attacks. design by integrating PoB with Raft, another classic supervision, called Beh-Raft-Chain. Our approach replaces Practical Byzantine Fault Tolerance (PBFT) Behavior-based Raft lower O(n) boost fault-toleration from n/4 n/3, where n is scale blockchain. In our solution, we weigh all based on their money behaviors, then set an adjustment parameter increase probability candidate being chosen beyond only few highest weight, order incentivize comparative experiments confirm Beh-Raft-Chain's theoretical low properties.
