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

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the perceived unfairness in the cryptocurrency trading landscape. Eighteen months later, his company, DoubleZero, claims to have a solution. The goal of DoubleZero is to eliminate the proximity to an exchange's servers as a competitive advantage for traders by utilizing a private fiber network that minimizes latency. This approach introduces a more equitable environment, even though regulators and traders have not yet demanded it. According to Federa, the issue stems from 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 physical laws governing data transmission lead validators to cluster in the same data centers. For instance, traders based in Tokyo enjoy a 200-millisecond advantage over their international counterparts on platforms like Hyperliquid. Federa notes that while Hyperliquid may appear decentralized from a governance and user perspective, it is not a distributed system due to its co-location 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's development of its Mahwah, New Jersey data center over a decade ago included cable-length equalization to within a nanosecond, not due to regulatory requirements, but because asymmetric access was detrimental to business. Traders who felt disadvantaged would simply route their orders to other venues. DoubleZero's solution involves timestamping, where the network 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 lies not only in speed but also in verifiability. On a venue using the public internet, a trader whose order arrives late cannot distinguish between ordinary network congestion and intentional interference. DoubleZero's 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 nearer competitor, the gap and variance shrink. Traders benefit from lower and more predictable latency, a property that high-frequency trading firms value in traditional markets. Federa's central argument 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 fair markets 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 does not rely on regulatory intervention but rather on the moment a major venue decides that fairness is a competitive advantage worth investing in. The next decade will test whether the crypto space can build distributed systems where the advantage is not based on server location.
