Data Subgraphs

The Graph is an indexing protocol for querying networks like Ethereum and IPFS.

Concept

The Hifi protocol emits events on the Ethereum blockchain, but querying these events is not quick and easy by default. That is where The Graph comes into play: it indexes the events Hifi emits on Ethereum and serves them via a high-throughput GraphQL server. The server is called a "subgraph".

Familiarity with GraphQL is requisite if you wish to consume our subgraph data in your application. Furthermore, you will need to install a GraphQL client like Apollo.

Links

Hifi is deployed on five Ethereum networks, as documented in the previous section Network Addresses. We are running a subgraph for each network:
