Former Solana Executive Tackles DeFi's Latency Issue with a Page from Wall Street's Book

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the unfairness he perceived 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 to an exchange's servers as a competitive advantage for traders by introducing a private fiber network that removes latency from the equation, thereby creating a more equitable environment. However, regulators and traders are not yet demanding this change. 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, which can give some traders a millisecond-based edge. For instance, on platforms like Hyperliquid, traders based in Tokyo have a roughly 200-millisecond advantage over their international counterparts. Federa notes that traditional finance has already dealt with this issue. The New York Stock Exchange developed its Mahwah, New Jersey data center over a decade ago and 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 venues. DoubleZero's solution involves timestamping. The network aggregates private bandwidth from operators to route blockchain data over dedicated links and provides venues with tools to timestamp orders across global entry points, reconstructing 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 cannot distinguish between ordinary network congestion and intentional delay. DoubleZero's pitch is that a 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 competitor in a closer region, the gap and variance in latency shrink. Traders get not just lower latency but also predictable latency, a property that high-frequency trading firms pay for in traditional markets. Federa's broader argument is that crypto misunderstands what makes traditional markets fair. Regulators are important, but they are not the primary drivers. In traditional markets, exchanges themselves work to maintain fairness because their business depends on it. Venues with a reputation for asymmetric access lose volume to those without. If Federa is correct, DeFi's latency problem does not require regulatory intervention but rather the moment a major venue decides that fairness is a competitive advantage worth investing in. The next decade will test whether the crypto industry is willing to build distributed systems where the advantage is not based on server location. As Federa puts it, 'No one wants to trade on an unfair platform.'
