The Zcash development team plans to introduce post-quantum signatures in January to protect public payments.

According to CoinDesk, the privacy cryptocurrency Zcash (ZEC) development team plans to introduce a post-quantum signature opcode on the network in January to support hash-based signatures, thereby defending against potential quantum computing attacks. This proposal primarily targets the transparent (public) payment pool, where approximately 70% of ZEC is currently held. Although developers have set January as the target deadline, the specific timing for network activation has not yet been finalized.
