Former Solana Executive Tackles DeFi's Latency Issue 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 cryptocurrency trading landscape. Eighteen months later, his company, DoubleZero, claims to have a solution. The goal of DoubleZero is to remove the proximity to an exchange's servers as a competitive advantage for traders by utilizing a private fiber network that reduces latency. This latency refers to the time it takes for an order to reach the platform from a trader's desk, thereby creating a more equitable environment. However, regulators and traders have yet to demand this solution. According to Federa, the issue lies in the fact that the crypto industry often confuses decentralized systems with distributed ones. 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 when milliseconds determine the outcome of a trade. For instance, on platforms like Hyperliquid, traders based in Tokyo have a roughly 200-millisecond advantage over their international counterparts. Federa explained in an interview with CoinDesk that "Hyperliquid may be a decentralized system from a governance and user perspective, but it is not a distributed system. It is still co-located in the same environment, even if it's run by multiple different entities." Traditional finance has already dealt with this issue. When the New York Stock Exchange developed its Mahwah, New Jersey data center over a decade ago, it implemented cable-length equalization to within a nanosecond because asymmetric access was detrimental to business, not just because regulators required it. Simply put, traders who felt disadvantaged would route their orders to other platforms. DoubleZero's solution involves timestamping. 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, similar to the cable equalization used by the NYSE. The challenge is not just about speed, but also verifiability. On a venue using the public internet, a trader whose order arrives late has no way to distinguish between ordinary network congestion and something more deliberate. Federa stated, "Is that true because the public internet drops packets all the time, or is that true because you saw my transaction and said, 'Hey, this guy's pretty good, I don't want to include this block?' The counter-factual is really hard to prove." DoubleZero's pitch is that a managed network with deterministic latency makes that distinction provable. Physics still applies: A New York trading desk using DoubleZero to reach Hyperliquid in Tokyo will not outrun a competitor located closer in AWS's ap-northeast-1 region. However, the gap narrows, 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 crypto is misinterpreting what makes traditional markets fair. Regulators matter, but they're not the primary driver. FINRA, the body that polices most of Wall Street's day-to-day conduct, is technically a voluntary self-regulatory organization. The Securities and Exchange Commission and Commodity Futures Trading Commission serve as backstops with enforcement teeth, but the day-to-day work of keeping markets fair is done by exchanges themselves. They do this because their business depends on it. Venues that gain a reputation for asymmetric access lose volume to venues that don't. If Federa is correct, DeFi's latency problem isn't waiting on regulators. It's waiting on the moment a major venue decides fairness is a competitive advantage worth paying for. Crypto has spent a decade proving it's possible to build decentralized systems. The next decade will test whether anyone wants to build distributed ones, where the advantage isn't based on the location of a server in Tokyo. As Federa said, "No one wants to trade on an unfair platform."
