[Zcash Developers Plan to Introduce Post-Quantum Signatures in January to Protect Transparent Payments] Zcash developers plan to introduce post-quantum signature opcodes into the network in January to support hash-based signature technology and defend against quantum computing attacks. This solution targets the transparent payment pool, which accounts for approximately 70% of the ZEC supply. The Zcash node validator, Zakura, has launched a wallet tool based on private information retrieval, allowing users to query balances across multiple addresses without revealing address associations to the server.
