The Graph is a decentralized protocol for indexing and querying data from blockchains. It functions like a search engine for the blockchain world, enabling developers to quickly and easily access the data they need for their decentralized applications (dApps). By using a decentralized indexing protocol, developers can specify which data they want to index and then perform efficient searches on that data. One could say that The Graph aims to be the decentralized answer to Google for data access. The Graph has become an essential tool within the blockchain ecosystem and supports several popular blockchains such as Ethereum and IPFS.
GRT (Graph Token) is the native cryptocurrency of The Graph protocol. It is used as an economic incentive to ensure that the network operates efficiently and securely. Network participants, such as indexers, curators, and delegators, use GRT to stake and are rewarded for their services that help maintain and improve the system. GRT also serves as a governance tool, giving holders the ability to vote on important decisions that affect the future of the protocol.
The Graph operates by using a decentralized network of indexers, curators, and delegators to index and query data from blockchains. Indexers run nodes that create indexes of data from specific subgraphs, making the data searchable. Curators identify which subgraphs are of high quality and should be indexed, while delegators stake their GRT tokens to reliable indexers to ensure the network's security and performance. Through GraphQL queries, developers can quickly and easily retrieve specific data for their dApps, saving time and resources.
Why does The Graph exist?
The Graph exists to solve the problem of quickly and efficiently accessing data from blockchains. Before The Graph, developers had to build and maintain their own indexing servers, which was both time-consuming and costly. The Graph automates this process by providing a decentralized and scalable way to index and search blockchain data. This enables faster development and better user experiences for dApps while contributing to the decentralization of infrastructure and reducing reliance on centralized services.
