Ethereum Query Language

(1) , (1) , (1) , (1)


Blockchains store a massive amount of heterogeneous data which will only grow in time. When searching for data on the Ethereum platform, one is required to either access the records (blocks) directly by using a unique identifier, or sequentially search several records to find the desired information. Therefore, we propose the Ethereum Query Language (EQL), a query language that allows users to retrieve information from the blockchain by writing SQL-like queries. The queries provide a rich syntax to specify data elements to search information scattered through several records. We claim that EQL makes it easier to search, acquire, format, and present information from the blockchain.
