The public internet wasn’t built for high-performance blockchains.In this episode of Fully Diluted, Messari’s Dylan Bane and Matthew Nay sit down with Austin Federa, co-founder of DoubleZero, to unpack how a global mesh of privately contributed fiber links is becoming the low-latency “private internet” for Solana and other high-throughput chains.

Austin explains why 20–30 hops over the public internet introduce jitter, slow block propagation, and widen trading spreads—and how DoubleZero’s 70+ fiber links, multicast, and future FPGA acceleration aim to fix it. They also get into the 2Z token, DZ SOL liquid staking, validator incentives, and what it will take to push Solana toward 100k+ TPS and eventually 1M+.

You’ll learn:

🔹 Why major financial firms and web2 giants don’t rely on the public internet—and why blockchains shouldn’t either

🔹 How DoubleZero’s contributors (Jump, DRW/Cumberland, and others) provide fiber that validators can “plug into” alongside the public internet

🔹 How jitter, least-cost routing, and bandwidth caps quietly limit DeFi and on-chain trading today

🔹 The design of the 2Z token and DZ SOL stake pool, and how they align network costs and validator economics

🔹 What multicast, edge filtration, and hardware acceleration could unlock for next-gen L1s and cross-chain apps

🔹 DoubleZero’s 2026 roadmap, new geographies and tenants, and how non-crypto systems might eventually tap the network
