The proposed protocol modification isolates swap addresses using private information retrieval to prevent future quantum computers from de-anonymizing historical wallet payments.
Key point 1 of 3
01
Zakura introduced a one-time incoming viewing key (ivk) architecture to shield Zcash swap users from future quantum decryption attacks.
Key point 2 of 3
02
Cross-chain swaps via NEAR Intents previously exposed user addresses on public ledgers, creating vulnerabilities to Shor's algorithm.
Key point 3 of 3
03
The solution integrates private information retrieval (PIR) to maintain fast wallet seed recovery without splitting hardware wallet balances.
Context
Publicly indexing shielded refund addresses on external chains exposed static viewing keys to prospective 'harvest now, decrypt later' quantum attacks.
Why it matters
Zcash wallet developers and users executing cross-chain transactions can prevent account-wide linking without breaking hardware wallet compatibility on Ledger and Keystone.
What to watch
Client wallet implementations of the one-time ivk standard and the eventual deployment of Zcash's native Tachyon post-quantum upgrade.
