GRT, also known as The Graph, is a decentralized protocol that enables developers to build and query open APIs, called subgraphs, that extract data from blockchain networks. The Graph aims to provide a decentralized infrastructure for Web3 applications, allowing developers to easily access and use blockchain data without the need for centralized intermediaries. The protocol is built on top of Ethereum and uses its smart contract functionality to enable secure and trustless interactions between users and subgraphs.

The Graph's main value proposition is its ability to provide a decentralized indexing and querying system for blockchain data. This allows developers to easily access and use blockchain data in their applications, without the need for complex and centralized infrastructure. The protocol is designed to be highly scalable and efficient, allowing it to handle large amounts of data and queries in a decentralized and secure manner. The Graph has already gained significant traction in the blockchain community, with a growing number of developers and projects using the protocol to build and deploy Web3 applications.
