Former Solana Executive Tackles DeFi's Latency Issue with Wall Street-Inspired Solution

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the unfairness in the crypto trading landscape. Eighteen months later, his company, DoubleZero, claims to have found a solution. The goal is to eliminate the proximity to an exchange's servers as a competitive advantage for traders by utilizing a private fiber network that minimizes latency and creates a more equitable environment, even if regulators and traders are not yet demanding it. The issue, according to Federa, lies in the fact that the crypto industry confuses decentralized systems with distributed ones. While DeFi protocols are decentralized due to their open-source code and permissionless validator sets, the laws of physics cause validators to cluster in the same data centers, giving some traders a significant edge. For instance, on platforms like Hyperliquid, traders based in Tokyo enjoy a roughly 200-millisecond advantage over their international counterparts. Federa notes that this problem is not new, as traditional finance has already faced similar challenges. The New York Stock Exchange, for example, developed a data center in Mahwah, New Jersey, over a decade ago, which included cable-length equalization to within a nanosecond to prevent asymmetric access. DoubleZero's solution involves timestamping, which aggregates private bandwidth from operators to route blockchain data over dedicated links and provides venues with tools to timestamp orders across global entry points, allowing for a fair sequence to be reconstructed. The main challenge is not just speed, but also verifiability, as traders have no way to distinguish between ordinary network congestion and deliberate actions on a venue running over the public internet. DoubleZero's managed network with deterministic latency makes this distinction provable. While physics still applies, and a New York trading desk routing through DoubleZero to reach Hyperliquid in Tokyo will not outrun a nearer competitor, the gap and variance shrink, providing traders with not just lower latency but also predictable latency. Federa's point is that crypto is misinterpreting what makes traditional markets fair, and that regulators are not the primary driver. Instead, exchanges themselves are responsible for maintaining fairness, as their business depends on it. If a major venue decides that fairness is a competitive advantage worth paying for, DeFi's latency problem may be solved without waiting for regulators. The next decade will test whether anyone is willing to build distributed systems, where the advantage is not based on the location of a server.
