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

Austin Federa, former head of strategy at the Solana Foundation, left his position in 2024 to address the perceived unfairness in the crypto trading landscape. Eighteen months later, his company, DoubleZero, claims to have found a solution. The goal of DoubleZero is to eliminate the proximity advantage that traders have when they are closer to an exchange's servers. By utilizing a private fiber network, the company removes latency as a factor and creates a more equitable environment, 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 crypto. While 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, giving some traders a significant edge. For instance, traders based in Tokyo enjoy a 200-millisecond advantage over their international counterparts on platforms like Hyperliquid. Federa notes that this problem has already been addressed in traditional finance. The New York Stock Exchange developed a data center in Mahwah, New Jersey, over a decade ago, which included cable-length equalization to prevent asymmetric access. This was not done due to regulatory requirements but because traders who felt disadvantaged would take their business elsewhere. 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. The challenge is not only 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 delays. 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 using DoubleZero to reach Hyperliquid in Tokyo will not outrun a competitor in a closer region, the gap and variance shrink. Traders receive not only lower latency but also predictable latency, which is a valuable property in traditional markets. Federa's broader point is that crypto misinterprets what makes traditional markets fair. Regulators play a role, but they are not the primary driver. The main factor is that exchanges themselves work to maintain fairness because their business depends on it. If a venue gains a reputation for asymmetric access, it loses volume to venues that do not. According to Federa, DeFi's latency problem does not rely on regulators but on the moment a major venue decides that fairness is a competitive advantage worth investing in. 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.
