Ethereum Foundation Launches Post-Quantum Security Hub as 10+ Client Teams Run Weekly Interop Devnets
The Ethereum Foundation publicly launched pq.ethereum.org as a central hub for its post-quantum security initiative. Over 10 Ethereum client teams are running weekly post-quantum interoperability devnets, with the effort spanning all protocol layers — execution (vector math precompiles), consensus (leanXMSS hash-based signatures), and data (post-quantum blob handling). The initiative targets major fork milestones with a years-long coordinated migration strategy designed to avoid disruptive 'flag day' upgrades.
