区块链财政电子票据数据跨链迁移的实践

Practice of Cross Chain Migration of Data of Blockchain Financial Electronic Bills

本文通过分析腾讯公司的TBaaS区块链底层和国内首个自主可控的“长安链”底层的技术架构和数据格式方面的差异,并结合区块链财政电子票据的业务特点,提出了采用数据重写处理方式的数据迁移方案。截止目前完成了几十万张区块链财政电子票据历史数据迁移的试点,具备了正式历史数据迁移的条件。实践证明了采用数据重写处理方式进行区块链财政电子票据历史数据迁移切实可行,对其他类型跨链历史数据迁移具有参考意义。

By analyzing the differences in technical architecture and data format between the bottom layer of tencent’s TBaaS blockchain and the bottom layer of China’s first autonomous and controllable"Chang’an Chain",and combined with the business characteristics of blockchain financial e-bills,this paper puts forward a data migration scheme using data rewriting processing.So far,the pilot of historical data migration of hundreds of thousands of blockchain financial electronic bills has been completed,and the conditions for formal historical data migration are met.Practice has proved that the historical data migration of blockchain financial electronic bills by using data rewriting processing method is feasible,and it has reference significance for other types of cross chain historical data migration.
