Subgraph (The Graph)

A subgraph is a specialized application programming interface (API) used by The Graph indexing and querying platform. It enables the creation of a global graph on the Ethereum network with essential public data. Software developers can then use, index, and serve blockchain data in a cryptographically verifiable manner. Subgraphs help reduce the centralized structure of conventional indexing servers, which typically demand significant engineering and hardware resources to access decentralized data securely.
