摘要： 分析和研究以太坊上的区块、交易、账户和智能合约数据具有巨大价值,但是以太坊数据量大、数据种类多、存储结构各异,当前数据获取方法的获取速度慢而且获取的数据不全,因此充分利用这些数据非常困难。文中提出了基于区块并行的以太坊数据快速导出工具Geth-query,通过分析以太坊内部机制,利用区块世界状态快照消除区块之间的依赖关系,优化本机资源利用效率并行重放区块,实现了快速而全面地提取以太坊链上数据。实验证明,Geth-query提取的数据种类丰富,数据导出速度相比传统方法提升了10倍左右。为了使用方便,文中同时对导出的数据进行存储优化,并在前端页面进行数据展示,从而为分析和研究以太坊提供了数据基础。
