Is Ethereum Realtime Ready | Kevin Lepsoe (ETHGas) at ETHConf

Sun, Aug 2, 2026, 12:00 AM

In this talk, Kevin Lepsoe, founder of ETHGas, asks whether Ethereum is real-time ready and walks through how restructuring block space can make it faster, more performant, and fairer. Coming from a TradFi background as an FX and interest rate options trader who led Morgan Stanley's structured credit group before 2008, then moving into tech, he now works at the core of Ethereum infrastructure. He frames the moment through two lenses: AI, where a significant and growing share of flow is now agent driven as tools like Claude Code and Codex reach everyday users, and yield, where nearly every institution's first foray onchain is the vault space (rebranded from asset management to curation), citing a recent yield summit at the NYSE run by Morpho. The problem is that Ethereum was built over 10 years ago for humans, not machines trading every millisecond, so it is slow and uncertain: a trade you expect in 12 seconds might take 24 or 36, which makes multi-agent coordination probabilistic and hard, and predictable agents and strategies are vulnerable to front running. Kevin argues the solution is block space. ETHGas got access to Ethereum's block space and made it tradable like a commodity such as oil and gas, letting participants speculate on, manage, and risk manage the scarce high grade resource that is Ethereum's core business. He explains how block builders currently reorder trades to maximize extraction, likening it to a nightclub letting the best trades in first, which is unfair and extractive. ETHGas instead inserts trades into the next block immediately and broadcasts the block state every 50 milliseconds, enabling real-time preconfirmations where users can trade multiple times within a 12-second slot with far greater speed and certainty. He shares study results: making Ethereum real-time could earn Uniswap LPs $2 to $3 billion a year while cutting the roughly $250 to $300 million of annual MEV extraction, and dramatically reduces event risk since prices jump far less over 50 milliseconds than over 12 seconds, mitigating the cascading liquidation risks seen in the Kelp situation. He closes on institutional block space, a whitelisted end-to-end framework with known validators, first come first serve non-extractive building, and compliance policies (like avoiding Tornado Cash) that lets TradFi players like BlackRock buy size onchain without being front run, noting around 70% of Ethereum validators are broadly aligned to move forward. 00:00 Introduction 00:52 Kevin's TradFi and Tech Background 01:18 Two Perspectives: AI and Yield 01:40 Why Everyone Is Using Agents Now 02:18 The Rise of Vaults and Curation 02:50 Why Ethereum Was Built for Humans, Not Machines 03:11 The Uncertainty of Landing a Trade 03:30 Why Multi-Agent Coordination Is Hard 03:59 Why AI Will Break Things Before Trillions Arrive 04:36 Why Predictable Agents Get Front Run 04:56 The Solution: Block Space 05:19 Making Block Space Tradable Like a Commodity 05:49 Refining Block Space for Higher Performance 06:17 Why Ethereum's Block Space Is Scarce and High Grade 06:50 How Blocks Are Made Today 07:18 How Trades Propagate Through the Ecosystem 07:55 The Nightclub Analogy for Extraction 08:13 Why It Is Unfair and Extractive 08:32 Creating Fast and Exciting Blocks 09:01 Trading Multiple Times in a Slot 09:25 Real-Time Preconfirmations at 50 Milliseconds 09:47 What It Means for DeFi 10:06 Why Uniswap LPs Would Make $2-3 Billion 10:34 Less MEV and Less Extraction 11:17 Why Vault Returns Should Be Higher 11:38 Reducing Event Risk and Gap Risk 12:14 How Slow Blocks Cause Liquidation Risk 12:37 Why Faster Blocks Reduce Systemic Risk 13:11 Introducing Institutional Block Space 13:50 How Big Players Avoid Being Front Run 14:14 The Fees TradFi Will Pay to Avoid Front Running 14:35 How Institutional Block Space Works 14:59 Compliance Policies Like Avoiding Tornado Cash 15:22 Accessing Ethereum Liquidity Without a New Chain 15:54 Where ETHGas Is Today 16:26 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ *ETHConf 2026* ETHConf is a 3 day event for founders, industry leaders, and builders who are excited about the possibilities of building on top of Ethereum.
