| 以超级账本（hyperledger fabric ，HF）为代表的联盟链技术在区块链应用市场有巨大潜力，能有效推动区块链技术在公共服务及特定领域中的集成应用创新发展。HF通过横向增加多链的方式实现可扩展性，它构造出的扁平的多链结构难以适配应用多级管理组织结构，同时横向的可扩展能力仍显不足且存在资源利用率低的状况。为解决前述问题，本文提出基于链分裂的自适应弹性纵向可扩展方法（chain division based adaptive elastic scalable method towards hyperledger fabric，Daes）。Daes依照有向无环图结构通过链分裂的纵向扩展方法提升HF的可扩展性，提升节点资源利用率，并能够生成灵活适配应用多级管理的多链结构。Daes通过交易机制实现扩展分裂，可以确保分裂过程的时耗可控、交易一致性以及子链策略安全。实验结果表明，较之传统的HF，Daes可以在等量节点资源下提供更高的交易吞吐量，并且纵向扩展机制能够灵活适配应用层级管理需要。在本文的实验环境下，Daes比传统HF可以提升60%~67%的交易吞吐量。 |

| The alliance chain technology represented by hyperledger fabric (HF) has great potential in the blockchain application market and can effectively promote the innovative development of integrated application of blockchain technology in public services and industries. HF achieves scalability by adding multi blockchains horizontally. The flat multi-chain structure constructed by HF is difficult to adapt to the multi-level management organization structure. Meanwhile, the horizontal scalability is still insufficient and the resource utilization rate is low. To solve those problems, this paper proposes a chain division based adaptive elastic scalable method towards hyperledger fabric (Daes). Daes enhances the scalability of HF and improves node resource utilization by employing a vertical expansion method based on the directed acyclic graph structure, and can generate a multi-chain structure that flexibly adapts to multi-level management of application. Daes implements vertical expansion through the transaction mechanism, which can ensure controllable time consumption, transaction consistency and sub chain strategy security in the splitting process. Experimental results show that, compared with traditional HF, Daes can provide higher transaction throughput under the same amount of node resources, and the vertical expansion mechanism can flexibly adapt to the needs of hierarchical management. In this experimental environment, Daes can improve the transaction throughput of traditional HF by 60%-67%. |
