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 in the cryptocurrency trading landscape. Eighteen months later, his company, DoubleZero, claims to have 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 introducing a more equitable environment, even if regulators and traders are not yet demanding 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 physical laws governing the speed of data transmission force validators to cluster in the same data centers, creating an uneven playing field. For instance, on platforms like Hyperliquid, traders based in Tokyo enjoy a roughly 200-millisecond edge 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." This problem is not unique to the cryptocurrency space, as traditional finance has already faced similar challenges. 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, not because regulators required it, but because asymmetric access was detrimental to business. Simply put, traders who felt disadvantaged would route their orders to other platforms. DoubleZero's solution involves timestamping, which 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. However, the challenge extends beyond speed to verifiability. On a venue operating over the public internet, a trader whose order arrives late has no way to differentiate between ordinary network congestion and intentional interference. As Federa pointed out, "The counter-factual is really hard to prove. 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?'" DoubleZero's managed network with deterministic latency makes this distinction provable. While physics still applies, and a New York trading desk routing through DoubleZero to reach Hyperliquid in Tokyo will not outrun a nearer competitor in AWS's ap-northeast-1 region, the gap narrows, and more importantly, the variance shrinks. Traders gain not just lower latency but also predictable latency, a property that high-frequency trading firms are willing to pay for in traditional markets. Federa's broader argument is that the cryptocurrency space is misinterpreting what makes traditional markets fair. Regulators play a role, but they are not the primary drivers. FINRA, the body responsible for policing 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 maintaining fair markets is done by exchanges themselves, as their business depends on it. Venues that gain a reputation for asymmetric access lose volume to venues that do not. If Federa is correct, DeFi's latency problem is not waiting on regulators; it is waiting for the moment a major venue decides that fairness is a competitive advantage worth investing in. The cryptocurrency space has spent a decade proving that decentralized systems can be built. 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 in Tokyo. As Federa stated, "No one wants to trade on an unfair platform."
