StreamingFast Firehose relayer component

Relayer Component in Detail

The Relayer component is responsible for providing executed block data to other Firehose components.

The Relayer component feeds from all available Reader nodes to get a comprehensive view of all possible forks.

The Relayer "fans out", or relays, block information to the other Firehose components.

Relayer & gRPC

The Relayer component serves its block data through the streaming gRPC interface BlockStream::Blocks. This is the same interface that the Reader component exposes to the Relayer component. Read more about the BlockStream::Blocks interface in its GitHub repository.
