The Graph | Avalanche Docs

Overview

Getting historical data on a smart contract can be frustrating when building a dapp. The Graph provides an easy way to query smart contract data through APIs known as subgraphs. The Graph’s infrastructure relies on a decentralized network of indexers, enabling your dapp to become truly decentralized.

Features

Decentralized Indexing: Enables indexing blockchain data through multiple indexers, thus eliminating any single point of failure
GraphQL Queries: Provides a powerful GraphQL interface for querying indexed data, making data retrieval super simple.
Customizable & Reusable: Define your own logic for transforming & storing blockchain data. Reuse subgraphs published by other developers.
Data Aggregation: Aggregates data from multiple blockchain sources, offering a unified view for easier access and analysis.
Scalability: Designed to handle large volumes of data and scale with the needs of growing dApps and data requirements.

Getting Started

Building a subgraph only takes a few minutes. It primarily consists of the following steps:

Initialize your subgraph project
Deploy & Publish
Query from your dapp

Use Cases

The Graph is ideal for a variety of blockchain data needs:

Decentralized Applications (dApps): Efficiently index and query data for dApps, enabling enhanced functionality and user experiences.
Data Aggregation: Aggregate data from multiple blockchain sources for comprehensive insights and analytics.
Data Retrieval: Provide fast and reliable data retrieval for applications that require access to blockchain data.
Analytics and Reporting: Use The Graph to collect and analyze blockchain data, supporting reporting and decision-making processes.

Conclusion

The Graph provides a robust solution for indexing and querying blockchain data. It effectively tackles the challenge of reading blockchain data without creating a centralized bottleneck. With its network of indexers, The Graph offers increased redundancy and quicker query responses. Using GraphQL queries, your dApp can pinpoint exactly the fields it requires.
