A Master-slave Multi-chain Hierarchical Cross-chain Model Based on Credit Voting Consensus

Abstract

This paper proposes a consensus algorithm based on the credit voting mechanism, which introduces the voting mechanism to decide the ownership of the accounting privilege, avoids the competition of the computation power among nodes, and makes all nodes in the system get the accounting privilege fairly. By assigning credit value to nodes, the influence of equity on the system can be reduced. Meanwhile, quantitative evaluation on the behavior of nodes can better prevent nodes conducting malicious behaviors. Based on PoVT, we propose a master-slave multi-chain layered cross-chain model, and conduct experiments to evaluate the performance. The results show that the efficiency of the system is improved, and the system has a certain defense capability against attack methods such as double spending attack, selfish mining, nothing-at-stake attack.
