Former Solana Executive Tackles DeFi's Latency Issue with a Wall Street-Inspired Solution

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the perceived unfairness in the cryptocurrency trading landscape. Eighteen months later, his new company, DoubleZero, claims to have found a solution. The goal of DoubleZero is to remove the proximity advantage that certain traders have when they are closer to an exchange's servers. By utilizing a private fiber network, the company seeks to create a more level playing field for traders, even if regulators and traders are not yet demanding it. According to Federa, the issue lies in the conflation of decentralized and distributed systems in the context of DeFi protocols. While these protocols are decentralized due to their open-source nature and permissionless validator sets, the physical laws governing data transmission lead to validators clustering in the same data centers. This results in a competitive disadvantage for traders who are farther away from these data centers. For instance, traders based in Tokyo have a roughly 200-millisecond advantage over their international counterparts on platforms like Hyperliquid. Federa emphasizes that even if a system is decentralized from a governance and user perspective, it may not be distributed, as it can still be co-located in the same environment. This problem is not unique to the cryptocurrency space, as traditional finance has already faced similar issues. The New York Stock Exchange, for example, implemented cable-length equalization in its Mahwah, New Jersey data center to ensure that all traders had equal access to the exchange, regardless of their physical location. DoubleZero's solution involves timestamping orders across global entry points, allowing for the reconstruction of a fair sequence of events. This approach aims to provide a more equitable environment for traders by minimizing latency and ensuring verifiability. The challenge lies not only in achieving speed but also in verifying the authenticity of transactions. On public internet venues, it can be difficult for traders to distinguish between ordinary network congestion and intentional manipulation. DoubleZero's managed network, with its deterministic latency, makes it possible to prove the distinction between these two scenarios. While the laws of physics still apply, and a New York-based trading desk may not be able to outrun a competitor in a closer region, the gap in latency is reduced, and more importantly, the variance in latency is minimized. This results in lower and more predictable latency, which is a key property that high-frequency trading firms value in traditional markets. Federa's argument is that the cryptocurrency space is misinterpreting what makes traditional markets fair. Regulatory bodies play a role, but they are not the primary drivers of fairness. Instead, it is the exchanges themselves that work to maintain fairness, as their business depends on it. Venues that gain a reputation for having asymmetric access tend to lose volume to those that do not. If Federa is correct, the latency issue in DeFi is not waiting on regulatory action but rather on the moment when a major venue decides that fairness is a competitive advantage worth investing in. The next decade will be crucial in determining whether the cryptocurrency space can build distributed systems, where the advantage is not based on physical location but on the principles of fairness and equality. As Federa puts it, 'No one wants to trade on an unfair platform.'
