Reputation Consensus Mechanism for Blockchain Based on Information-Centric Networking

This integration implies that the network state information ofICN can significantly impact consensus efficiency. However, the Ethereum Casper FFG consensusalgorithm overlooks the network heterogeneity among consensus nodes, leading toa potential bottleneck in consensus efficiency, especially when nodes with inferior networkquality participate.

To address this issue, this paper proposes a multidimensional reputationmodel based on an ICN-enabled blockchain architecture. The model combines onchainstake and network contributions to evaluate the reputation of ICN consensus nodes.Furthermore, a reputation-based hybrid consensus mechanism, RepuICN, is introduced,which enhances the network layer of the Casper FFG algorithm. This mechanism selectshigher-reputation ICN consensus nodes as proposers for checkpoint blocks, mitigatingthe impact of network latency fluctuations on block propagation.
