## Questions

### What is StreamingFast's relationship to The Graph protocol?

StreamingFast is one of The Graph's designated core developers, alongside Edge & Node and Figment. The firm is responsible for building and maintaining Firehose and Substreams — the data-extraction and parallelized-processing layers that power the protocol's decentralized indexing network. Under a multi-year service agreement announced in March 2022, StreamingFast receives token grants from The Graph Foundation linked to defined technical milestones (per the firm's official communications, March 2022).

### What is Firehose and how does it differ from standard node RPC endpoints?

Firehose is StreamingFast's proprietary extraction layer that transforms real-time blockchain data into a flat, deterministic byte stream. Unlike standard RPC endpoints that deliver individual block responses, Firehose produces a continuous, replayable stream that enables parallelized processing. This architecture reduces indexing latency from hours to seconds for high-throughput chains like Solana, and is the technical foundation for Substreams — the next-generation indexing engine deployed across The Graph ecosystem.

### Does StreamingFast operate as a for-profit entity or a non-profit core developer?

StreamingFast operates as a privately held, for-profit entity headquartered in Montreal, Canada. While the firm receives grant-based compensation from The Graph Foundation for its core-developer role, it also operates a separate commercial arm that sells Firehose endpoints and data-engineering services directly to enterprise clients including exchanges and analytics firms. This dual posture — core-dev responsibilities paired with independent commercial contracts — distinguishes its operating model from foundation-only development shops.

### What blockchains does StreamingFast support?

StreamingFast supports Ethereum, Solana, Arbitrum, Polygon, BNB Chain, NEAR, and Cosmos-based chains through its Firehose infrastructure. The firm has historically focused on high-throughput environments where traditional node-indexing methods fail, prioritizing chains that generate data volumes exceeding what conventional PostgreSQL-based indexers can process in real time (per the firm's public documentation).

### Who competes with StreamingFast in the blockchain indexing space?

StreamingFast's direct competitors include Alchemy, QuickNode, and SubQuery — all of which offer various forms of blockchain data indexing and API infrastructure. However, StreamingFast's Firehose architecture, built around byte-stream extraction rather than database-coupled indexing, represents a fundamentally different technical approach. In the decentralized-indexing category, the firm's Substreams framework competes with Subsquid's indexing toolkit, though the two are designed for different protocol architectures (The Graph vs. a standalone indexing network).

### How does StreamingFast's personnel composition reflect its technical posture?

StreamingFast's roughly 30-person team comprises principally systems engineers with deep expertise in low-latency data processing, compiled languages such as Rust and Go, and stream-processing frameworks. The firm recruits heavily from Montreal's concentration of AI and systems-programming talent, and its two co-founders — Alexandre Bourget and Matthieu Vachon — previously built dfuse, an early high-performance API platform for the EOS blockchain. No formal organizational chart or executive team beyond the co-founders has been publicly disclosed.
