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

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the perceived unfairness in the crypto trading environment. Eighteen months later, his company, DoubleZero, claims to have a solution. The goal of DoubleZero is to remove the competitive advantage that traders gain from being physically closer to an exchange's servers. By utilizing a private fiber network, the company aims to reduce latency and create a more equitable trading environment, even if regulators and traders are not yet demanding it. According to Federa, the issue stems from the fact that cryptocurrency often confuses decentralization with distribution. While DeFi protocols are decentralized due to their open-source code and permissionless validator sets, the physical location of validators can still provide a significant advantage. For instance, traders based in Tokyo enjoy a 200-millisecond edge over their international counterparts on platforms like Hyperliquid. Federa notes that this problem has already been encountered in traditional finance. The New York Stock Exchange, for example, developed its Mahwah, New Jersey data center over a decade ago, implementing cable-length equalization to within a nanosecond to prevent asymmetric access. DoubleZero's solution involves timestamping orders across global entry points, allowing venues to reconstruct a fair sequence of events. The challenge lies not only in speed but also in verifiability. On a venue using the public internet, a trader who experiences delayed orders has no way to distinguish between ordinary network congestion and deliberate interference. DoubleZero's managed network with deterministic latency makes it possible to prove the difference. While physics still applies, and a New York trading desk cannot outrun a competitor in a closer region, the gap in latency shrinks, and more importantly, the variance in latency decreases. Traders gain not only lower latency but also predictable latency, which is a valuable property in traditional markets. Federa argues that the crypto industry has misinterpreted what makes traditional markets fair. Regulators play a role, but they are not the primary drivers of fairness. Instead, exchanges themselves work to maintain fair markets because their business depends on it. Venues that gain a reputation for asymmetric access lose volume to those that do not. If Federa is correct, DeFi's latency issue is not waiting on regulators but rather on the moment a major venue decides that fairness is a competitive advantage worth investing in. The next decade will test whether the industry is willing to build distributed systems where the advantage is not based on the physical location of servers.
