基于区块链的一体化应急应战机制

Integrated Emergency-Defense System Based on Blockchain

我国应急与应战体系设置分散,信息沟通渠道缺失,协调机制不健全,导致动员效能不高,资源调度冲突,指挥协调不畅,亟须融合应急与应战体系,以提升一体化应急应战能力。针对这一现状,应用区块链技术设计以专家系统为监管决策层、P2P(Peer-to-Peer)网络为自治决策层的一体化应急应战机制。基于应急应战事件位置、事件时间和事件类别建立三维区块链模型,对不同等级、不同模式下的应急应战资源协同配置问题进行统一描述。考虑一体化应急应战场景与常规点对点交易场景的区别,设计信用证明作为区块链共识机制。最后,在以太坊开发框架下搭建有限节点参与的一体化应急应战区块链原型系统并进行仿真,仿真结果证明基于区块链的一体化应急应战机制是合理且可行的。

The emergency-defense system of China is decentralized,lacking information communication channels and coordination mechanisms.This condition results to low mobilization efficiency,resource scheduling conflicts and poor coordination perfor-mance,which highlights the urgency to upgrade the capacity of integrated emergency-defense system.In response to this situation,this paper studies the integrated emergency-defense mechanism with the expert system as the supervisory decision-making layer and the P2P(Peer-to-Peer)network as the autonomous decision-making layer.Based on the location,time and category of emergency response events or national defense events,a three-dimensional blockchain model is established to describe resource scheduling problems in different situations.Considering the difference between the integrated emergency-defense scenario and the conventional peer-to-peer transaction scenario,a consensus mechanism based on credit certificate is designed.Finally,an integrated emergency-defense blockchain prototype system of limited nodes to participate is built on Ethereum.Simulation results of the prototype system prove that the blockchain based integrated emergency-defense mechanism is reasonable and feasible.
