The Graph is a decentralized indexing protocol that allows developers to efficiently query blockchain data, making it easier to build and scale decentralized applications (dApps). The platform enables developers to create and deploy subgraphs, which are open APIs that index data from various blockchains and make it easily accessible for dApps. The Graph supports multiple blockchain networks, including Ethereum, IPFS, and more, allowing developers to query data across different ecosystems. The platform is designed to be highly efficient and scalable, ensuring that dApps can retrieve the data they need in real-time. The Graph is widely used in the DeFi space and other blockchain applications where access to accurate and timely data is crucial.
