Former Solana Executive Utilizes Wall Street Strategy to Promote Fairness in DeFi

Austin Federa, the former head of strategy at the Solana Foundation, left his position in 2024 to address the perceived inequities in the cryptocurrency trading landscape. Eighteen months later, his company, DoubleZero, is poised to introduce 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 reduces latency. This approach aims to create a more equitable environment, despite the fact that 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 the speed of data transmission lead validators to cluster in the same data centers. For instance, on platforms like Hyperliquid, traders based in Tokyo enjoy a latency advantage of approximately 200 milliseconds over their international counterparts. Federa notes that traditional finance has already addressed this issue. 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 because regulators mandated it, but because asymmetric access was detrimental to business. DoubleZero's solution involves timestamping. The network aggregates private bandwidth from operators to route blockchain data over dedicated links, providing venues with tools to timestamp orders across global entry points and reconstruct a fair sequence. The challenge is not only speed but also verifiability. On a venue using the public internet, a trader whose order arrives late has no way to distinguish between ordinary network congestion and intentional interference. DoubleZero's managed network with deterministic latency makes it possible to prove the distinction. While physics still applies, and a New York trading desk using DoubleZero to reach Hyperliquid in Tokyo will not outrun a competitor in a closer region, the gap and variance in latency are reduced. Traders benefit from not only lower latency but also predictable latency, a property that high-frequency trading firms value in traditional markets. Federa's argument is that the crypto industry 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 issue 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 the industry is willing to build distributed systems, where the advantage is not based on server location, but rather on the quality of the platform.
