The Ethlabs research group has proposed making Ethereum quantum-resistant by 2027, with full-capacity post-quantum transactions as its final goal. The first post-quantum transactions would cost more because they would occupy more space on the blockchain, although no fee estimate has been provided. Users would have to migrate to new accounts and use compatible wallets, while the draft EIP-8141, known as Frame Transactions, would enable custom transaction validation and key rotation. Ethlabs would combine this mechanism with the SPHINCS post-quantum signature scheme, while upgrading consensus and achieving full scale would remain separate tasks. Ethlabs plans to withdraw its Quick Slots proposal from the Hegotá roadmap and redirect its resources toward pqai27.
