Cardano has opened a formal review for CIP-0197, a proposal written by researcher Robert Phair that would add optional post-quantum protection to hierarchical deterministic wallets through a zero-knowledge-proof signature layer. The proposal is designed to address future risks tied to quantum computing while letting users strengthen the security of existing wallet addresses without having to migrate keys right away. The proposal remains at an early stage. It has not been deployed on the Cardano mainnet and is not a mandatory requirement. Its stated purpose is to give the ecosystem time to test, discuss and refine a post-quantum security path before any wider rollout. The next phase is community and technical review. Developers will examine the proposal’s feasibility, efficiency, security profile and compatibility with existing wallet infrastructure, according to the report cited by Techub News from Bitcoinist.

Cardano has opened a formal review for CIP-0197, a proposal written by researcher Robert Phair to add optional post-quantum protection to hierarchical deterministic wallets through a zero-knowledge-proof signature layer.

The proposal is meant to address future risks from quantum computing. Under the design, users could strengthen the security of existing wallet addresses without immediately migrating their keys.

CIP-0197 is still at an early stage. It has not gone live on the Cardano mainnet and is not a mandatory requirement.

Its purpose is to give the ecosystem time to test, discuss and refine a post-quantum security path.

The proposal will next move into community and technical review, where developers will assess its feasibility, efficiency, security and compatibility with existing wallet infrastructure.
