Efficient Gossip-Based Protocol in the Neo Blockchain Network

Abstract

Peer-to-peer (P2P) networks, together with other distributed systems, must meet strict efficiencyrequirements in terms of the information dissemination process. Rapid message transmission affectsthe entire functionality of the network, including data processing, attack resistance, topology changes,etc. In this article, we look at the most common network protocols based on gossip, explore andcompare several approaches to improve the information dissemination model. We describe the Neoblockchain network protocol, which extends gossip algorithms to distribute messages over a P2Pnetwork. Based on the simulation results, we build a model of the Neo blockchain network protocoland evaluate the effectiveness of the Neo network protocol in terms of reactive message processing inseveral scenarios, propose protocol improvements and evaluate the resulting performance gain.

A Survey on Network Optimization Techniques for Blockchain Systems

“…Berendea et al [31] and Shaleva et al [72,73] altered the steps and communication pattern of the gossip algorithm used by the Hyperledger Framework and Neo Blockchain, respectively, to reduce its bandwidth usage and also to reduce the amount of time it uses. In their approach, whenever a peer receives a new block, it constantly shares it with a new set of uniformly and randomly selected neighbors until the dissemination counter is exhausted.…”
