What is The Graph?
The Graph is a data aggregation and retrieval platform built for the Ethereum blockchain.
This project aims to solve the issues surrounding data retrieval on the Ethereum blockchain, as it can be difficult for applications (dApps) built on Ethereum to retrieve essential data required for apps to function properly.
Similar to how Google indexes websites, trawling through all website data to allow users to access it, The Graph does a similar job — but on the Ethereum blockchain. The Graph indexes the Ethereum network, aggregates all the data it finds, and then makes it available on The Graph’s marketplace in the form of “subgraphs” — almost like how specific folders of information would be stored on a computer hard drive.
Participants of The Graph’s platform, knows as “Indexers”, help to connect Ethereum blockchain app developers with information stored across the Ethereum network. Indexers earn rewards for their participation in the for of The Graph’s native token, GRT. Whereas, dApp developers who want to access information using The Graph’s platform will pay for the information using the GRT token.
