Graph Node

The Graph blockchain protocol is designed to index and query data from blockchains, and the Graph Node tool makes this possible. Graph Node is a Rust-based framework that acts as a master server to event source the Ethereum blockchain (the system’s only supported blockchain) and its corresponding subgraphs. It updates a data store deterministically, which can be queried and searched using the GraphQL endpoint. Graph Node is the main server that performs the processes required to obtain answers to complex queries from blockchain databases.
