The Graph
Blockchain Indexer
The Graph is an indexing protocol that organizes blockchain data for easy access via GraphQL.
What Is The Graph?
The Graph is a decentralized protocol that enables efficient indexing and querying of blockchain data. It serves as a crucial infrastructure layer for Web3 applications, allowing developers to access on-chain data without running their own nodes.
The Graph functions similarly to a search engine for the blockchain. It organizes blockchain data into a structure that can be easily queried using GraphQL, a popular query language. This is done through subgraphs, which are open APIs that define how to extract and structure data from smart contracts and blockchain events.
By using The Graph, developers can build applications that require real-time access to blockchain data, such as decentralized finance (DeFi) platforms, NFT marketplaces, and other Web3 services.
Key Components
Subgraphs: Open APIs that index data from blockchain networks. Developers can create their own subgraphs or use existing ones to access specific data relevant to their applications.
Substreams: A feature that allows for real-time and historical data streaming, providing more granular control over data processing.
Token API: A standardized interface for accessing token-related data, such as balances and prices, simplifying the integration of token information into applications.
