Episode notes
Performance Plus Decentralization
- Bulk blends sub-20ms performance with decentralization using a distributed validator operator set.
- They provide a dedicated perp environment tuned for low latency traders and market makers.
Make Onboarding Plug-And-Play
- Provide a simple API to onboard sophisticated flow rather than forcing them to build transaction-landing infrastructure.
- Let market makers focus on pricing and spreads instead of engineering landing reliability and priority fees.
Sidecar Validator Client
- Bulk runs a forked validator client (Bulk Agave) as a sidecar to keep heavy matching and risk off Solana's block path.
- That preserves composability while enabling compute-heavy risk simulation and rapid matching.
