Zakura Proposes Fix to Stop Quantum Attackers Linking Zcash Shielded Swaps

The proposal targets a narrow but consequential weakness: the reuse of one published address as a common thread that a future quantum adversary could pull to deanonymize shielded swap activity. It matters most for Zcash users who rely on shielded swaps for privacy, and for the developers weighing how to harden the protocol before quantum capability arrives. Whether this fix moves from proposal to implementation, and how it affects existing address practices, is the open question worth tracking.
