The Graph —— A Decentralized Query Protocol Designed for Blockchains
**Website** **Explorer** Documentation
Graph is a decentralized protocol for indexing and querying blockchain data, and the Graph currently supports indexing data from Ethereum, IPFS and POA, with more networks coming soon. Graph makes data query simple and easy to operate. Anyone can build and publish open APIs, known as subgraphs, to make data easily accessible.
The GRT token is an Ethereum-based ERC-20 work token that’s used to allocate different resources within the ecosystem. The GRT token is used to incentivize all players of the network to create continuously improving APIs. This is because all Indexers, Delegators, and Curators are paid in GRT tokens depending upon the performance of the indexes or subgraphs.
The total initial GRT token supply is set at 10 billion, with issuance at 3% each year. The GRT token is also burned through various mechanisms. Both the aforementioned deposit tax for Curator and Delegator tokens are burned, in addition to 1% of the query fees.
Graph tokens have two main uses in the protocol:
Indexer pledge: The indexer pledges Graph tokens so that it can be discovered by the query market and provides economic security during the execution of the work.
Curator's signal: Curators pledge Graph tokens to the curatorial market to predict which subgraphs are valuable to the network, and they will be rewarded for correct predictions.
Users can pay ETH or DAI for inquiries. But the final settlement will be done in GRT to ensure that a common account unit is used throughout the agreement.
In addition, holding native tokens can also stimulate certain behaviors through inflation. The ability to dynamically adjust monetary policy for inflation is a powerful tool in the toolbox.
The team member information listed on the official website; the background of the entire team member can be considered very luxurious.
The team members include: Project Lead is Taniv Tal, graduated from the University of Southern California with a major in EE; and previously founded the React development environment Workflo, and the catering industry payment app Tapsavvy. He has also worked as a development engineer in companies such as HP and Mulesoft.
Tech Lead is Jannis Pohlmann, graduated from Universität zu Lübeck, Germany, majoring in computer and human-computer interaction, and previously worked for Workflo, Codethink and other companies.
Community Lead is Rodrigo Coeldo. He graduated from the Department of Industrial Engineering at Arizona State University. He was a serial entrepreneur before and founded a P2P mobile encrypted communication platform called cSuite.
Project consultants include Esteban Ordano, CTO of Decentraland, and Zaki Manian of Tendermint Labs.
The 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 create and publish using the open API provided by it Index data.
From this, it can be seen that all indexers/curators/delegators need to pledge GRT tokens in order to use the network.
