Firehose-enabled Node

StreamingFast Firehose Firehose-enabled node component

Firehose-enabled Node in Detail

The Firehose-enabled Blockchain Node is a third-party blockchain node client, such as Ethereum, instrumented under StreamingFast practices to output data that will be read by the Firehose Reader component.

Note: The Reader component will consume the data produced by the Firehose-enabled Blockchain Node.

The Firehose-enabled Blockchain Node runs in tandem with the Reader component. The two components are connected either through a UNIX pipe using stdout, or by having the Reader component's process execute and fork the blockchain client. This is accomplished using the node-manager software included in Firehose.

Blockchain nodes used in this capacity require:

• very few features,

• no archive mode capability,

• no JSON-RPC service,

• and no indexed data will be queried.

The Firehose-enabled Blockchain Node is responsible for executing all transactions in an order respecting the consensus protocol of the blockchain.
