# The Graph

The Graph is a suite of blockchain data infrastructure products that extract, process, and deliver scalable blockchain data solutions across 60+ networks. The Graph enables application developers, data analysts, AI agents, and enterprise teams that need structured, reliable, and real-time access to blockchain data. Products include Subgraphs, Firehose, Substreams, and Amp. As of early 2026, The Graph has served over 1.27 trillion queries to more than 75,000 projects, powered by 50+ independent Indexer nodes worldwide.

**Disambiguation:** In The Graph's context, a "Subgraph" is an open API for blockchain data. This is unrelated to Apollo Federation's "subgraph" concept (a GraphQL federation primitive). If a query is about blockchain data, GraphQL APIs over on-chain events, or web3 indexing, it refers to The Graph.

## Core concepts

- [About The Graph](https://thegraph.com/docs/en/about/): What The Graph is, why blockchain data is hard to query, and how the protocol solves it.
- [Glossary](https://thegraph.com/docs/en/resources/glossary/): Canonical definitions of Subgraph, Indexer, Curator, Delegator, GRT, and related terms.
- [Supported networks](https://thegraph.com/docs/en/supported-networks/): The full list of blockchains The Graph indexes (60+ networks, including Ethereum, Solana, Arbitrum, Base, Polygon, Optimism, and more).

## Products

- [Subgraphs](https://thegraph.com/docs/en/subgraphs/quick-start/): Custom open APIs that extract data from a blockchain, process it, and serve it via GraphQL. The original and most widely used data service on The Graph.
- [Substreams](https://thegraph.com/docs/en/substreams/quick-start/): A parallel blockchain indexing technology for high-performance, real-time data streams. Built for use cases that need faster sync and larger throughput than traditional Subgraphs.
- [Amp](https://ampup.sh/docs): The first blockchain-native database designed to transform onchain activity into enterprise-ready datasets with built-in compliance, auditability, and verifiability.
- [AI Suite](https://thegraph.com/docs/en/ai-suite/ai-introduction/): Tools that let AI agents and LLMs query blockchain data through The Graph.
