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 what he perceived as an unfairness in the cryptocurrency trading environment. Eighteen months later, his company, DoubleZero, claims to have a solution. DoubleZero seeks to remove the proximity to an exchange's servers as a competitive advantage for traders by introducing a private fiber network that minimizes latency. This approach aims 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 crypto. While DeFi protocols are decentralized due to their open-source code and permissionless validator sets, the need for speed pushes validators to cluster in the same data centers, effectively making them non-distributed. For instance, on platforms like Hyperliquid, traders based in Tokyo have a roughly 200-millisecond advantage over their international counterparts. Federa notes that this problem has already been addressed in traditional finance. The New York Stock Exchange developed its Mahwah, New Jersey data center over a decade ago, implementing cable-length equalization to within a nanosecond to prevent asymmetric access, which is detrimental to business. DoubleZero's solution involves timestamping orders across global entry points, allowing for the reconstruction of a fair sequence. The network aggregates private bandwidth from operators to route blockchain data over dedicated links, providing venues with tools to timestamp orders. The main challenge is not only 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 delays. DoubleZero's 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 competitor in a nearby region, the gap and variance in latency shrink. Traders get lower and more predictable latency, a property that high-frequency trading firms value in traditional markets. Federa argues that crypto misinterprets what makes traditional markets fair, emphasizing that regulators are not the primary drivers. Instead, exchanges themselves work to maintain fairness because their business depends on it. If a major venue decides that fairness is a competitive advantage worth investing in, DeFi's latency problem may be resolved without waiting for regulators. The next decade will test whether the crypto industry is willing to build distributed systems, where the advantage is not based on server location.
