Hyperclique: A Novel P2P Network Structure for Blockchain Systems

This paper presents a novel P2P broadcast network called Hyperclique, which assigns a coordinate value to each peer in the network with adjustable dimensionality. Based on the concept of a clique, nodes whose coordinate values differ in only one dimension form one clique in Hyperclique. Hyperclique offers several advantages over the current P2P network topology, including a shorter network diameter and tighter network density. The node degree and average path length can be adjusted based on the network's actual conditions. Combining the coordinates with smart contract will result in extra-savings in both broadcast messages and convergence time. This paper provides a comparative analysis of the Hyperclique structure and other popular structured P2P topologies, demonstrating that Hyperclique outperforms them in improving the performance of P2P overlay networks. Additionally, the Hyperclique system supports various blockchain upper layers and is a promising and secure solution to improve the performance of blockchain networks.
