Goldsky is a platform for real-time reading from blockchain. Rather than reading directly from RPC nodes or pre-defined APIs, Goldsky aims to provide everyone with the necessary tools to build reliable, real-time applications without having to perform data manipulation in their front-end or back-end. By defining a source, users can obtain a data stream that they can manipulate using SQL and other tools. Multiple transformed streams can be layered on top of each other to create alerts, new views, merge data, and more. The results of your transformations can be accessed through a GraphQL API, or directly in your own back-end via real-time ETL.
