On November 17, 2025, Federico Carrone delivered a talk at EthDay, the opening event of Devconnect Argentina at La Rural in Buenos Aires.12 He spoke alongside Vitalik Buterin, Danny Ryan, and Jesse Pollak.1
The argument: Ethereum is not a world computer. It is a verifiable computer—a system where every computation can be proved and every claim checked without re-executing the work.
Verifiable, not fast
The world computer framing invited the wrong comparisons, as though Ethereum were competing with AWS on throughput. The verifiable computer distinction is more precise. Ethereum is not optimizing for speed. It is the only computer where you do not need to trust the operator.
Performance
Carrone argued for increasing the gas limit by 100x, targeting 1 Gigagas. With work from Nethermind, Reth, and LambdaClass’s Ethrex client, he considers 300-400 Megagas achievable on adequate hardware.
On Layer 2s, the assessment was direct: most implementations are not working. The path forward requires simpler rollup operations and decentralized sequencers that remove dependency on centralized cloud infrastructure.
Post-quantum preparation
LambdaClass is building ethlambda, a Lean consensus client designed for cryptographic resilience against quantum computing. Work that pays no dividend today but prevents structural failure later.
Tone
The cultural message was plain. Carrone cited Andy Grove—“Only the paranoid survive”—and warned against complacency. The Ethereum ecosystem has succeeded enough to become comfortable.
