Ethereum Researchers Drop Faster Block Plan to Prioritize Quantum Security
Ethlabs is withdrawing its Quick Slots proposal, which would shorten Ethereum’s block interval from 12 to 10 seconds, to prioritize a new post-quantum security roadmap, pqai27. The plan targets quantum-resistant consensus and account authentication by 2027, followed by work to restore network performance at scale. It also keeps Frame Transactions central and says FOCIL should proceed only if it does not delay security work. Ethlabs cites future quantum attacks and AI-assisted vulnerability discovery, while acknowledging neither threat currently breaks Ethereum’s protections. The proposal is more aggressive than the Ethereum Foundation’s existing 2029 quantum-resistance target and would require coordination among developers, wallet providers, validators, and users.
