Ex-Solana Executive Utilizes Wall Street Strategy to Promote Fairness in DeFi

Austin Federa, former head of strategy at the Solana Foundation, left his position in 2024 to address the perceived unfairness in the crypto trading environment. Eighteen months later, his company, DoubleZero, claims to have a solution. The goal of DoubleZero is to remove the competitive advantage of proximity to an exchange's servers for traders by utilizing a private fiber network that minimizes latency. This network is designed to create 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 the crypto space. While DeFi protocols are decentralized due to their open-source code and permissionless validator sets, the physical laws governing data transmission lead validators to cluster in the same data centers, giving some traders a millisecond-based edge. For instance, traders based in Tokyo using platforms like Hyperliquid have a roughly 200-millisecond advantage over their international counterparts. Federa notes that traditional finance has already encountered this problem. The New York Stock Exchange developed a data center in Mahwah, New Jersey, over a decade ago, incorporating cable-length equalization to ensure symmetric access and prevent traders from seeking alternative platforms due to feelings of disadvantage. DoubleZero's approach involves timestamping orders across global entry points, allowing venues to reconstruct a fair sequence of events. This is achieved by aggregating private bandwidth from operators to route blockchain data over dedicated links. The challenge is not only about speed but also about verifiability, as traders need to distinguish between ordinary network congestion and potential manipulation. DoubleZero's managed network with deterministic latency makes such distinctions provable. While physics still applies, and a New York trading desk cannot outrun a competitor in a closer region, the gap and variance in latency shrink. Traders gain not just lower latency but also predictable latency, a property highly valued in traditional markets. Federa argues that crypto misinterprets what makes traditional markets fair, emphasizing that while regulators are important, they are not the primary drivers of fairness. Instead, exchanges themselves work to maintain fairness because their business depends on it, and venues with a reputation for asymmetric access lose volume to those that do not. If Federa is correct, DeFi's latency problem does not rely on regulatory action but rather on the moment a major venue recognizes fairness as a competitive advantage worth investing in. The next decade will test whether the crypto industry is willing to build distributed systems where advantages are not based on server location.
