WebIt is considered as a new generation of disruptive technology. However, the underlying storage of blockchain only provides limited support for data query. This limits the utility of blockchain technology. To improve the efficiency of access to blockchain data, we design EtherH based on Ethereum, the most representative open blockchain system. WebEtherQL, an efficient query layer for Ethereum – the most representa-tive open-source blockchain system. EtherQL provides highly efficient query primitives for analyzing blockchain data, including range queries and top-k queries, which can be integrated with other applications with much flexibility.
