摘要:

区块链对等网络在复杂网络应用中的核心问题是对等扁平的区块链网络结构与层级体系不相适应。对此,文章提出区块链层级网络结构、层级共识方式和层级账本结构,并给出层级区块链网络应用。通过分析表明,文章所提方案共识方式从全网节点对等共识转变为兄弟节点层级共识,提高了共识效率;数据流向通过分层关联账本实现了横向同步和纵向汇聚,信息保护实现了按层分级、受控。

关键词: 区块链, 层级网络结构, 层级共识, 分层关联账本, 数据汇聚

Abstract:

The core problem in the application of blockchain peer-to-peer network in national defense is that the peer-to-peer flat blockchain network structure does not adapt to the hierarchical system. In this regard, this paper proposes the hierarchical network structure of blockchain, hierarchical consensus mode, hierarchical ledger structure and information classification and presentation mode. The simulation results show that the consensus mode of the proposed scheme changes from peer-to-peer consensus of the whole network nodes to consensus of the sibling nodes, which improves the consensus efficiency; the data flow realizes horizontal synchronization and vertical convergence through hierarchical associated ledgers; and the information protection realizes hierarchical and controlled protection.

Key words: blockchain, hierarchical network, hierarchical consensus, hierarchical ledger, data aggregation
