Cardano Prepares for Quantum-Resistant Wallets

Cardano's community is taking steps to future-proof wallet security against potential quantum computing threats. Researchers have proposed CIP-0197, a design that adds optional post-quantum wallet protections using zero-knowledge proof layers.

This approach allows users to strengthen their existing wallet addresses without immediately migrating keys, reducing friction in the transition process.

Quantum computing poses a long-term risk to blockchain networks, and wallets are one of the most sensitive areas. Users may hold assets for years, making them vulnerable to key exposure.
