Zakura Proposes Per-Swap Viewing Keys to Close Quantum Privacy Gap

The proposal treats quantum risk as a privacy problem rather than only a settlement one, narrowing the blast radius of a single compromised key to one swap instead of an entire address history. That matters most for users of shielded ZEC routed through NEAR Intents, where cross-chain execution already widens the set of parties exposed to key material. The design is still under review, so whether per-swap key isolation survives review and how it interacts with existing viewing-key workflows are the open questions worth tracking.
