Zcash Developers Propose Quantum‑Safe Key Scheme for ZEC Transactions
Current overview (not historical)
Zcash developers, led by Zakura, have announced a new quantum‑resistant design that assigns a unique viewing key to each ZEC transaction processed through NEAR Intents. The goal is to prevent future quantum computers from reconstructing the payment history of shielded swaps. The proposal keeps the viewing key in the user’s wallet and employs private information retrieval techniques so that the wallet can locate refund addresses without revealing the query address. According to the team, compatible software wallets could adopt this open‑source feature within weeks, aiming to meet the January quantum‑resistance payment target. While the plan has been welcomed by the community, some skeptics question whether the private retrieval approach fully mitigates the risk of quantum‑based linkability. Nonetheless, the developers emphasize that the scheme is a practical step toward safeguarding Zcash’s privacy against emerging quantum threats.

Report first recorded Oct 19, 19:00
Zcash full node developer Zakura has proposed "one-time" viewing keys to prevent future quantum computers from linking a user's shielded Zcash payments. The fix targets swaps through NEAR Intents, where a user's shielded address is posted on NEAR's public chain. The approach requires no network upgrade and uses private information retrieval to avoid slowing down wallet restoration. If a quantum computer breaks one posted address, it will only learn about payments to that specific address, not others.

Report first recorded Oct 19, 13:46
Zcash developers plan to assign a unique viewing key to each ZEC swap made through NEAR Intents, limiting the payment history a future quantum computer could reconstruct from publicly posted refund addresses. The proposal keeps spending keys with users while using private information retrieval to help wallets locate refunds without revealing which addresses are being checked.
