概述
The Graph 是一个去中心化索引协议，旨在整理区块链数据，并通过 GraphQL 查询使其易于访问。它使开发者能够构建快速、可靠且可扩展的去中心化应用（dapps），而无需运行自己的数据服务器或构建复杂的索引基础设施。通过将区块链数据索引为称为“子图”（subgraphs）的开放式 API，The Graph 使应用程序能够高效且低延迟地查询数据。
The protocol operates through a decentralized network of participants including Indexers, Curators, Delegators, and Subgraph Developers. Indexers run nodes that index data and serve queries, Curators signal which subgraphs are valuable, Delegators support Indexers by staking tokens, and Developers create subgraphs to organize smart contract data. This distributed model ensures high availability, resilience, and censorship resistance with 99.99%+ uptime.
The Graph supports a wide range of blockchain networks and hosts over 75,000 projects with more than 1.27 trillion queries served. It is widely used in DeFi, NFTs, DAOs, analytics, and gaming applications. Developers can start by creating or using existing subgraphs, query data with GraphQL, and integrate results into their frontends. The Graph also offers advanced features like Substreams for streaming data and a Token API for token balances and prices. Comprehensive documentation, a rich ecosystem of community subgraphs, and active developer support make onboarding straightforward.
问题
Accessing and organizing blockchain data is complex and resource-intensive. Developers face challenges running their own indexing infrastructure, parsing raw blockchain data, and ensuring reliable, low-latency data access for decentralized applications.
