Former Solana Executive Tackles DeFi Inequality with Innovative Network 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, is now ready to launch its solution. The goal of DoubleZero is to eliminate the competitive advantage that traders gain from being physically closer to an exchange's servers. By utilizing a private fiber network, the company aims to reduce latency and create a more equitable environment for all traders, even if regulators and traders are not yet demanding it. According to Federa, the issue 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 some traders having a significant edge over others. For instance, traders based in Tokyo who use platforms like Hyperliquid 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." This problem is not unique to the cryptocurrency industry, 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. 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. However, the challenge is not only 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 intentional interference. Federa pointed out that "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 pitch is that a 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 in AWS's ap-northeast-1 region, the gap and variance shrink. Traders gain not just lower latency but also predictable latency, which is the property that high-frequency trading firms pay for in traditional markets. Federa's broader argument is that the cryptocurrency industry is misinterpreting what makes traditional markets fair. Regulators play a role, but they are not the primary driver. FINRA, the organization that oversees 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 the exchanges themselves. They do this because their business depends on it. Venues that gain a reputation for asymmetric access lose volume to venues that do not. If Federa is correct, the latency problem in DeFi is not waiting for regulators to step in. Instead, it is waiting for the moment when a major venue decides that fairness is a competitive advantage worth investing in. The cryptocurrency industry has spent a decade proving that it can build decentralized systems. The next decade will test whether anyone wants to build distributed ones, where the advantage is not based on the physical location of a server. As Federa stated, "No one wants to trade on an unfair platform."
