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

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the unfairness he perceived in the cryptocurrency trading landscape. Eighteen months later, his company, DoubleZero, claims to have found a solution. DoubleZero aims to eliminate the proximity to exchange servers as a competitive advantage for traders by introducing a private fiber network that minimizes latency. This network is designed to create a more equitable environment, even though 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. Although 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 lead to latency issues. For instance, on platforms like Hyperliquid, traders based in Tokyo have a roughly 200-millisecond advantage over their international counterparts. Federa notes that while Hyperliquid may appear decentralized from a governance and user perspective, it is not a distributed system, as it is still co-located in the same environment. This problem is not unique to the crypto space, as traditional finance has already faced similar challenges. 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 can be detrimental to business. DoubleZero's solution involves timestamping, which aggregates private bandwidth from operators to route blockchain data over dedicated links. This allows venues to timestamp orders across global entry points and reconstruct a fair sequence, similar to the cable equalization used by the NYSE. The challenge is not only speed but also verifiability, as a trader whose order arrives late cannot distinguish between ordinary network congestion and intentional delay on a venue running over the public internet. 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 nearer competitor, the gap and variance shrink. Traders receive not only lower latency but also predictable latency, a property that high-frequency trading firms value in traditional markets. Federa's broader point is that the crypto space misinterprets what makes traditional markets fair. Regulators play a role, but they are not the primary drivers. Instead, exchanges themselves work to maintain fairness because their business depends on it. Venues with a reputation for asymmetric access lose volume to those that do not. If Federa is correct, DeFi's latency problem is not waiting on regulators but rather 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. As Federa puts it, 'No one wants to trade on an unfair platform.'
