摘 要：区块链系统的交易处理能力较弱使其无法广泛应用，分片是在不降低去中心化程度情况下解决区块链瓶颈的最佳技术，但目前主流的分片方案存在牺牲安全性来提升性能的问题。通过对现有分片方案进行研究，提出了基于节点属性的分片方案，根据节点属性和节点随机分配方法开展了网络分片、交易分片和状态分片。实验结果表明基于节点属性分片的区块链系统在满足系统安全的条件下提升了交易处理能力。

Abstract: The weak transaction processing capability of blockchain system makes it unable to be widely used. Fragmentation is the best technology to solve the blockchain bottleneck without reducing the degree of decentralization. However, the current mainstream fragmentation scheme has the problem of improving performance at the expense of security. Based on the research of existing fragmentation schemes, a fragmentation scheme based on node attributes is proposed. According to node attributes and node random allocation method, network fragmentation, transaction fragmentation and state fragmentation are carried out. The experimental results show that the blockchain system based on node attribute fragmentation improves the transaction processing ability under the condition of meeting the system security.
Keywords: blockchain; extensibility; node attribute; fragmentation technology
