Interest is growing in a low-cost proposal aimed at preparing Ethereum for the post-quantum era. Wu Blockchain reported that Nico, leading the Ethereum Foundation privacy project Kohaku, said Ethereum can begin preparing accounts for post-quantum security without requiring a hard fork.
According to Nico, the proposed account-level solution would cost approximately $0.07 per account to deploy. The design has completed an initial review with Fable, with additional audits planned.
“Ethereum can already start preparing accounts for a post quantum world, without waiting for a hard fork. Today, it would be just $0.07. Further audits incoming. Though I squeezed in a review with Fable before Uncle Sam crashed my party. Verity formal proof included for my lean enjoyers,” Kohaku tweeted.
Quantum computers are expected to eventually break ECDSA, the signature scheme used to secure Ethereum and Bitcoin accounts today. The article notes that recent resource estimates by Babbush et al. have brought this timeline closer than previously expected, making post-quantum signature verification at the execution layer an urgent issue.
The next step described by Ethereum researchers is a proposal centered on SPHINCS-, aiming to introduce efficient Stateless Post-Quantum Signature Verification on the EVM.
Coinbase has launched a High Yield USDC vault within its in-app DeFi lending offering, adding a second lending option that provides exposure to a wider range of collateral assets. The product is powered by Morpho infrastructure and uses vault allocations curated by Steakhouse Financial.
