Graph is a decentralized protocol for indexing and querying blockchain data, applied to Ethereum. Graph makes data query simple and easy to operate. Anyone can build and publish open APIs, aka subgraphs, making data easily accessible.

Graph tokens have two main uses in the protocol:

Indexer Staking: Indexers stake Graph tokens in order to be discovered by the query market, while providing economic security in the process of performing work.
Curator Signals: Curators stake Graph tokens into the curation market to predict which subgraphs are valuable to the network, and they are rewarded for correct predictions.
Users can pay ETH or DAI for inquiries. But the final settlement will be in GRT to ensure a common unit of account used throughout the protocol.

In addition, holding native tokens can also incentivize certain behaviors through inflation. The ability to dynamically adjust monetary policy for inflation is a powerful tool in the toolbox.

Project Introduction

This project is a decentralized data indexing protocol that can index and query data in the blockchain and storage network (such as data from Ethereum, IPFS and other Web3 data sources), allowing users to use the open API it provides Create and publish index data. (Note: The Graph is equivalent to "Baidu" in the blockchain world)

The Graph network consists of four types of participants:
One is users, who use GRT tokens to pay for indexing;
The other is indexers, who run network nodes and stake GRT , to make a profit whenever a user queries data;
The third is the manager, who uses GRT to indicate which subgraphs are worth indexing;
The fourth is the delegator, who pledges GRT to the node to earn income.
From this, it can be seen that indexers/managers/delegators need to pledge GRT tokens to use the network.
