Former Solana Executive Utilizes Wall Street Strategy to Promote Fairness in DeFi

Austin Federa left his position as head of strategy at the Solana Foundation in 2024 to address the perceived inequalities in the cryptocurrency trading environment. Eighteen months later, his company, DoubleZero, claims to have found a solution. DoubleZero seeks to eliminate the proximity to an exchange's servers as a competitive advantage for traders by utilizing a private fiber network that minimizes latency, thereby creating a more equitable environment, even though regulators and traders have yet to demand it. According to Federa, the issue lies in the fact that the cryptocurrency space often confuses decentralization with distribution. Although DeFi 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, resulting in an unfair advantage for some traders. For instance, on platforms like Hyperliquid, traders based in Tokyo have a roughly 200-millisecond edge over their international counterparts. Federa notes that traditional finance has already faced similar challenges, citing the New York Stock Exchange's development of its Mahwah, New Jersey data center, which implemented cable-length equalization to within a nanosecond to prevent asymmetric access. DoubleZero's solution involves timestamping, where the network aggregates private bandwidth from operators to route blockchain data over dedicated links, providing venues with tools to timestamp orders across global entry points and reconstruct a fair sequence. 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 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 argues that crypto is misinterpreting what makes traditional markets fair, and that regulators are not the primary drivers. Instead, it is the exchanges themselves that ensure 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 resolved 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.
