Cardano has initiated a formal review of CIP-0197, a proposal to add optional post-quantum protection for hierarchical deterministic wallets using a zero-knowledge proof layer. This upgrade aims to enhance wallet security against future quantum computing threats without forcing users to immediately change keys. The proposal, authored by Robert Phair, is still in early review and not yet implemented or mandatory. Developers and wallet providers will assess its practicality and security before any adoption, fitting Cardano's long-term approach to protocol upgrades.
