摘　　要：比特币区块链存储的海量非结构化数据不利于构建高效虚拟货币交易监管系统。其数据结构化转换面临两个技术挑战:一是数据量大,结构化转换效率有待显著提升;二是现有交易模型仅提供交易的单向链接,导致结构化转换过程复杂。为应对上述挑战,创新地提出一种高效的交易重构方案,并设计实现比特币区块链全量数据结构化转换系统,提供结构化数据的复杂查询和下载功能。相较现有平台,系统功能完善、性能高效,能为非法资金追踪等应用场景提供双向溯源、字段丰富的高质量数据,有力地推动了高效虚拟货币交易监管系统的构建。The massive unstructured data stored in Bitcoin blockchain is not conducive to construct an efficient virtual currency transaction supervision system.The data structured conversion of Bitcoin blockchain faces two technical challenges.(1)The efficiency of structured conversion needs to be significantly improved due to the large volume of data.(2)The existing transaction model unidirectionally links transactions from the current senders to previous transaction receivers,resulting in a complex structured conversion process.To address these challenges,we propose an efficient transaction reconstruction scheme and implement a full-volume data structured conversion system of Bitcoin blockchain.The system provides the services of data complex query and data download.Compared with the existing platforms,the system has complete functions and efficient performance.This system provides bi-directional traceability and field-rich Bitcoin blockchain data for application scenarios such as illegal bitcoin tracking,which strongly contributes to constructing the efficient virtual currency transaction supervision system.
