                Firehose

                Firehose Logo

                Firehose is a new technology developed by StreamingFast working with The Graph Foundation. The product provides previously unseen capabilities and speeds for indexing blockchain data using a files-based and streaming-first approach.

                The Graph merges into Go Ethereum/geth with the adoption of Live Tracer with v1.14.0 release⁠.

                Firehose extracts, transforms and saves blockchain data in a highly performant file-based strategy. Blockchain developers can then access data extracted by Firehose through binary data streams. Firehose is intended to stand as a replacement for The Graph’s original blockchain data extraction layer.
