Abstract:
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.
