The Graph

The Graph is an indexing protocol for querying data for networks like Ethereum and IPFS, powering many applications in both DeFi and the broader Web3 ecosystem. Anyone can build and publish open application programming interfaces (APIs), called subgraphs, that applications can use GraphQL to retrieve blockchain data. There is a hosted service in production that makes it easy for developers to get started building on The Graph. The Graph currently supports indexing data from Ethereum, IPFS, and POA. More networks are coming soon.

GRT is an Ethereum token that powers The Graph, a decentralized protocol for indexing and querying data from blockchains. 

Just as Google indexes the web, The Graph indexes blockchain data from networks like Ethereum and Filecoin. This data is grouped into open APIs called subgraphs that anyone can query.
