[CoinDesk] Ethereum researchers drop faster blocks to race toward quantum defenses in 2027

Ethereum researchers have abandoned faster block times to prioritize quantum-resistant account security, with Ethlabs targeting quantum-safe accounts for next year even though wallet holders must still migrate signing methods themselves. The shift matters because it reorders core protocol priorities around post-quantum cryptography ahead of a 2027 defense deadline. Watch for the account abstraction and signature-scheme migration path that users and wallet providers will need to adopt.
