TOKEN2049, Singapore: It was fascinating to catch-up with Jeff Feng is the cofounder of Sei Labs. He is one of the most ambitious forces redefining the future of blockchain infrastructure. Before venturing into Web3, Feng built his career in high finance, first as an investment banker at Goldman Sachs and later as a venture investor at Coatue Management, one of New York’s most sophisticated hedge funds. That experience gave him deep insight into how trading systems and markets work at scale. Today, he brings that Wall Street precision to the blockchain world, blending traditional trading logic with the openness and speed of decentralized finance. Sei Labs, the team behind the Sei Network, isn’t just building another blockchain. They’re reengineering how decentralized trading happens. Sei is a Layer 1 blockchain purpose-built for high-speed trading applications — the kind of foundation decentralized exchanges (DEXs) have dreamed about but never had. It’s designed to process over 12,000 transactions per second, finalize in as little as 300 milliseconds, and do so with near-zero latency. At the heart of Sei’s innovation is what it calls Twin Turbo consensus, a mechanism that dramatically reduces block times by overlapping communication and computation steps, ensuring that data moves through the chain almost instantaneously. Combined with “market-based parallelization,” Sei simultaneously handles multiple trades and smart contract executions without congestion. This means no more waiting, no more network clogs, the kind of efficiency high-frequency traders feasted on in traditional markets, now reborn on-chain. But Sei is not just about sheer speed; it’s about specialization. By embedding an order-matching engine directly into the base layer, it allows decentralized exchanges to rival centralized exchanges in execution quality. It’s the first blockchain to truly treat trading as a first-class citizen, ensuring every swap, trade, or arbitrage opportunity has the same lightning-fast responsiveness you’d expect from Wall Street systems, only without the gatekeepers. This focus on performance and usability has already drawn over 800,000 daily active users and $600 million in total value locked (TVL). The upcoming “Sei Giga” upgrade will push that even further, boasting projected throughput of 200,000 transactions per second through its new Autobahn consensus layer. In a world where Ethereum still struggles with network fees and Solana wrestles with reliability, Sei positions itself as the sleek, turbocharged challenger built specifically for the next wave of financial dApps. So why tune into this episode? Because Jeff Feng is not just talking about software — he’s architecting the rails of a new financial internet. This is a story of speed meeting purpose, of a blockchain that doesn’t want to be everything to everyone — it just wants to be the best at what matters most: trading. If Ethereum is the city and Solana the highway, Sei is the bullet train, modern, efficient, unstoppable. This is where finance meets physics, and Jeff Feng is in the driver’s seat.
