The Graph is a decentralised, Ethereum (ETH)-based indexing protocol that enables users to query data from various blockchains. The platform data can be transformed, organised, and shared across applications for anyone to query with just a few keystrokes. In addition, anyone can integrate their decentralised applications by building and opening so-called subgraphs (open APIs) instead of operating proprietary indexing servers. Roles in the Graph network include node operators referred to as Indexers, subgraph developers referred to as Curators, Delegators, who help to secure the network by delegating GRT and Consumers, the end-users who pay query fees for their applications.
