Former Solana Executive Tackles DeFi Inequality 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 he perceived in the crypto trading environment. Eighteen months later, his company, DoubleZero, claims to have found a solution. The company's goal is to eliminate the proximity to an exchange's servers as a competitive advantage for traders by utilizing a private fiber network, which reduces latency and promotes a more equitable environment. Federa argues that the crypto space mistakenly equates decentralization with distribution, as DeFi protocols, despite being decentralized due to their open-source code and permissionless validator sets, still cluster in the same data centers due to the laws of physics. This results in validators being pushed to the same data centers, giving some traders a significant edge. For instance, traders based in Tokyo enjoy a 200-millisecond advantage over their international counterparts on platforms like Hyperliquid. Federa notes that this issue is not new, as traditional finance has already faced similar challenges. 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, 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. This allows for the reconstruction of a fair sequence, similar to the cable equalization used by the NYSE. The challenge lies not only in speed but also in 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 it possible to prove the distinction. 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 broader point is that crypto misinterprets what makes traditional markets fair, and it is not regulators that drive fairness but rather the exchanges themselves, 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.
