Episode notes
Parallel High‑Performance Network
- Double Zero builds a parallel, high-performance internet owned by many independent parties to unblock distributed systems.
- It targets the same performance class as hyperscalers and HFT firms while remaining suitable for blockchains by avoiding single-company control.
From Solana To Double Zero
- Austin left Solana after seeing validator clients like Firedancer push million TPS designs that the public internet couldn't support.
- He and cofounders with private networking backgrounds formed Double Zero to let clients reach their real throughput limits.
Multicast And Hardware Acceleration
- Double Zero pairs dedicated fiber with FPGAs, packet deduplication, and multicast to reduce bandwidth waste and jitter.
- Multicast allows a validator to send one copy and have network switches replicate it at the edge instead of sending many end-to-end copies.
