The Graph
The Graph (GRT) is a decentralized and open-source indexing protocol for blockchain data. Developers can build and publish various APIs called subgraphs that perform queries over the GraphQL.

How does The Graph Work?

To index Ethereum-based data, The Graph uses the “Subgraph Manifesto.” This refers to the description of a subgraph that contains data about smart contracts, blockchain events, and the process of mapping event data together before it is all stored in the platform’s database.
GraphQL is the link between the blockchain data and the application a user wants to feed it to. Finally, after the whole process, users can view their query results from within their applications.
Some popular applications include AAVE, Aragon, Balancer, DAOstack, Uniswap, Synthetix, and many others are already using The Graph.
