Technical Stack: FPGAs, Deduplication, and Multicast

Join Alex Golding as he sits down with Austin Federa, Co-founder of DoubleZero, to explore how they're building permissionless high-performance fiber infrastructure that could revolutionize blockchain performance. Austin shares the technical vision behind creating a parallel internet for distributed systems, starting with Solana validators as their initial market.

🎯 Key Highlights

▸ The internet bottleneck: why high-performance blockchains are hitting infrastructure limits

▸ Building a parallel internet with dedicated fiber, FPGAs, and multicast technology

▸ Proof of utility: weaponizing greed and capitalism for positive-sum network outcomes

▸ 16% of Solana network already running on testnet despite limited infrastructure

▸ Technical deep-dive: signature verification, packet deduplication, and jitter reduction

▸ Token economics and bandwidth contribution models vs traditional staking

▸ Long-term vision: replacing IP addresses with public-private key routing
