Making Ethereum 240x Faster: From 12 Seconds to 50ms | Kevin Lepsoe

In this episode of Talking Tokens, Jacquelyn Melinek speaks with Kevin Lepsoe, Founder of ETHGas, about blockspace and how a transparent blockspace futures marketplace could redefine Ethereum’s core economic engine. Kevin explains why Ethereum’s 12-second block time creates fragmentation, poor UX, failed transactions, and institutional reluctance and how slicing blocks into millisecond-resolution windows unlocks a completely new operating model for L1s. He walks through his background as a trader during the 2008 crisis, why MEV behavior can mirror predatory high-frequency trading tactics, and why institutions won’t put billion-dollar balance sheets onchain in the current environment. Kevin also explains how ETHGas enables instant confirmations, how blockspace futures create the first native yield curve on any blockchain, and why this unlocks fixed-income products, cross-chain arbitrage, and a path toward deeper L1 liquidity. They discuss its upcoming Token Generation Event (TGE) as well as validator incentives, governance design, airdrops, its Open Gas Initiative, and how gas abstraction can onboard everyday users into an easier Ethereum experience. Kevin also shares why real-time Ethereum could support new classes of trading, lending, and insurance products and why 2026 may be the year blockspace becomes a mainstream asset class.
