摘要
针对单层区块链存在效率低、数据吞吐量少,无法处理多种数字资产应用的问题,文中开展了联合区块链的研究并进行科技成果转化。首先对公有链、私有链和联合链进行划分,构建基于可信节点的用户区块链、数据区块链的多链联合区块链结构。将用户数据与交易敏感数据分离,并使用工作量证明机制作为联合链的共识算法及使用主动动态授权拜占庭容错算法,从而提高联合区块链共识算法的数据吞吐量。数据测试结果表明,与单链区块链相比,多链区块链结构具有更低的计算量与通信量,同时也具有更高的数据吞吐量,可以有效应对大量数据并发的应用环境。
In view of the low efficiency and data throughput of single⁃layer blockchain,which can not deal with a variety of digital asset applications,this paper carried out the research of joint blockchain,and carried out the transformation of scientific and technological achievements.First of all,the public chain,private chain and joint chain are divided,and a multi chain joint blockchain structure based on user blockchain and data blockchain of trusted nodes is constructed,which separates user data and transaction sensitive data;the workload proof mechanism is used as the consensus algorithm of joint chain,and the Byzantine fault⁃tolerant algorithm of active dynamic authorization is used to improve the consensus calculation of joint blockchain Data throughput of.Data test results show that,compared with single chain blockchain,multi chain blockchain structure has lower computation and communication,but also has higher data throughput,which can effectively cope with a large number of concurrent data application environment.
