The Graph takes a new approach to open data with the first decentralized indexing protocol. The Graph is a protocol for organizing blockchain data that is already powering many DeFi and Web3 applications today. With the use of subgraphs (open APIs), developers can easily access blockchain data and serve data to their users.
To ensure economic security of The Graph Network and the integrity of data being queried, participants stake and use Graph Tokens (GRT). GRT is a work token that is an ERC-20 on the Ethereum blockchain, used to allocate resources in the network. Active Indexers, Curators and Delegators can provide services and earn income from the network, proportional to the amount of work they perform and their GRT stake.
