Former Solana Executive Utilizes Wall Street Strategy to Enhance DeFi Fairness

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the issue of unfairness in the cryptocurrency trading environment. Eighteen months later, his company, DoubleZero, claims to have found a solution. The goal of DoubleZero is to eliminate the proximity to an exchange's servers as a competitive advantage for traders by utilizing a private fiber network that removes latency as a factor, thereby creating a more equitable environment. However, regulators and traders have yet to express interest in this solution. According to Federa, the problem lies in the fact that the cryptocurrency industry often confuses decentralization with distribution. Although 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, which can result in a competitive advantage for certain traders. For instance, on platforms like Hyperliquid, traders based in Tokyo have a significant edge over their rivals abroad due to their proximity to the exchange's servers. Federa notes that this issue is not unique to the cryptocurrency industry, 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 ensure that all traders had equal access to the exchange. DoubleZero's solution involves timestamping, which allows venues to reconstruct a fair sequence of orders across global entry points. The network aggregates private bandwidth from operators to route blockchain data over dedicated links, providing venues with tools to timestamp orders and ensure a fair sequence. One of the major challenges is not just speed, but also verifiability. On a venue running over the public internet, a trader whose order arrives late has no way to distinguish between ordinary network congestion and intentional interference. DoubleZero's pitch is that a managed network with deterministic latency makes it possible to prove the fairness of the system. 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 shrinks, and more importantly, the variance shrinks. Traders get not just lower latency but predictable latency, which is the property high-frequency trading firms actually pay for in traditional markets. Federa's broader point is that the cryptocurrency industry is misreading what makes traditional markets fair. Regulators matter, but they are not the main driver. The day-to-day work of keeping markets fair is done by exchanges themselves, as their business depends on it. If a major venue decides that fairness is a competitive advantage worth paying for, the cryptocurrency industry may see a significant shift. The next decade will test whether anyone wants to build distributed systems, where the advantage is not based on the location of a server. As Federa notes, 'No one wants to trade on an unfair platform.'
