The Graph

Key Technical Advantages:

Decentralized Query Protocol: The Graph implements a decentralized query protocol to allow users to query a network for data without relying on centralized infrastructure. It combines ideas from distributed computing and cryptoeconomics to create a self-organizing, secure, and robust network. This protocol enables data-intensive decentralized applications (dApps) to be built with trust, metering, predictable performance, data availability, price efficiency, and incentive alignment. Protocol Stack: The Graph's protocol stack consists of several sub-protocols, including the consensus layer, peer-to-peer network, storage layer, query processing, payment channels, governance, query marketplace, and indexing and caching marketplace. These layers work together to facilitate the decentralized query protocol. GraphQL: The Graph supports GraphQL as its query language. GraphQL is a query language created and open-sourced by Facebook. It is designed to be flexible and well-suited for running queries from front-end applications, making it ideal for dApps that require no centralized infrastructure. Data Model: In The Graph, queries are executed against data sources composed of a schema and one or more datasets. The schema is a GraphQL SDL schema that defines entities, values, types, and relationships. The dataset defines data stored on public blockchains or decentralized storage networks such as IPFS/Swarm, and consists of data, mappings, and an optional update function. Network Participants and Economic Agents: The Graph's network includes several types of participants and economic agents, such as dApp clients, gateway nodes, P2P nodes, query nodes, end users, dApp developers, node operators, data source curators, and validators. These participants and agents interact within the network to perform their respective roles, contributing to the overall functioning of the decentralized query protocol.
