Ethereum unveils quantum-safe accounts, with a costly catch
Ethlabs proposed pqai27, a phased plan to prepare Ethereum for quantum-resistant accounts and consensus by 2027. Users could migrate early and make quantum-resistant transactions, but these would cost more because they use more data. Full-scale support for transactions and rollup data would depend on later signature aggregation and post-quantum data-availability upgrades. The proposal builds partly on draft EIP-8141, or Frame Transactions, which would enable alternative signature validation and key rotation. Consensus design, wallet support and user migration remain unresolved; the 2027 full-capacity goal is a stretch target, not a confirmed upgrade schedule. Ethlabs also plans to withdraw its Quick Slots proposal and redirect resources to pqai27.
