Ex-Solana Executive Tackles DeFi's Latency Issue with a Page from Wall Street's Playbook

Austin Federa, former head of strategy at the Solana Foundation, left his role in 2024 to address the unfairness in crypto trading. Eighteen months later, his company, DoubleZero, claims to have a solution. The goal is to eliminate the proximity advantage that traders near an exchange's servers have, creating a more level playing field. This is achieved through a private fiber network that minimizes latency, allowing for a more equitable environment. However, regulators and traders have yet to demand such a solution. According to Federa, the issue stems from the conflation of decentralized and distributed systems in DeFi protocols. While these protocols are decentralized due to their open-source code and permissionless validator sets, the need for speed pushes validators to cluster in the same data centers, despite being run by different entities. This problem is not new, as traditional finance has faced similar challenges. The New York Stock Exchange, for example, developed a data center with cable-length equalization to prevent asymmetric access. DoubleZero's approach involves timestamping orders across global entry points, allowing for a fair sequence of trades. The challenge lies not only in speed but also in verifiability, as traders need to distinguish between ordinary network congestion and deliberate actions. DoubleZero's managed network aims to provide deterministic latency, making it possible to prove the difference. While physics still applies, and a New York trading desk cannot outrun a competitor in a nearer region, the gap and variance in latency shrink. This provides traders with not only lower latency but also predictable latency, a property that high-frequency trading firms value in traditional markets. Federa argues that crypto misinterprets what makes traditional markets fair, emphasizing that regulators are not the primary drivers. Instead, exchanges themselves work to maintain fair markets, as their business depends on it. The adoption of DoubleZero's solution may not rely on regulators but rather on the decision of a major venue to prioritize fairness as a competitive advantage. The next decade will test whether the crypto industry is willing to build distributed systems, where the advantage is not based on server location.
