Former Solana Executive Tackles DeFi's Latency Disadvantage with Wall Street-Inspired Solution

Austin Federa, previously the 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 of a trader to an exchange's servers as a competitive advantage, thereby creating a more equitable environment for traders. This is achieved through the use of a private fiber network that minimizes latency, which is the time it takes for an order to reach the platform from a trader's desk. Although regulators and traders are not currently demanding this, DoubleZero aims to introduce a more level playing field. According to Federa, the issue lies in the conflation of decentralized and distributed systems within 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. For instance, traders based in Tokyo using platforms like Hyperliquid have a roughly 200-millisecond advantage over their international counterparts. Federa notes that even if a system is decentralized from a governance and user perspective, it may not be truly distributed if all entities are operating within the same environment. This problem has already been encountered in traditional finance. When the New York Stock Exchange developed its Mahwah, New Jersey data center over a decade ago, it implemented cable-length equalization to within a nanosecond to avoid asymmetric access, which can be detrimental to business. Simply put, traders who feel disadvantaged will redirect their orders to other platforms. DoubleZero's solution involves timestamping. The network aggregates private bandwidth from operators to transmit blockchain data over dedicated links, providing venues with tools to timestamp orders across global entry points and reconstruct a fair sequence, similar to the cable equalization used by the NYSE. However, the challenge extends beyond speed to verifiability. On a venue operating over the public internet, a trader whose order arrives late has no way to distinguish between ordinary network congestion and intentional interference. DoubleZero's pitch is that a managed network with deterministic latency makes it possible to prove the distinction. While physics still applies, with a New York trading desk routing through DoubleZero to reach Hyperliquid in Tokyo not being able to outrun a competitor in a closer region, the gap and variance in latency are reduced. Traders gain not only lower latency but also predictable latency, a property that high-frequency trading firms are willing to pay for in traditional markets. Federa's broader argument is that the crypto industry is misinterpreting what makes traditional markets fair. Although regulators play a role, they are not the primary drivers. It is the exchanges themselves that ensure fairness, as their business depends on it. Venues that develop a reputation for asymmetric access lose volume to those that do not. If Federa is correct, DeFi's latency issue is not dependent on regulatory intervention but rather on the moment a major venue recognizes fairness as a competitive advantage worth investing in. The crypto industry has spent the last decade demonstrating the feasibility of building decentralized systems. The next decade will test whether there is a desire to build distributed systems, where the advantage is not based on the physical location of a server. As Federa puts it, 'No one wants to trade on an unfair platform.'
