On October 11, the Zcash full node development team, Zakura, announced that the network is expected to introduce a quantum-resistant signature opcode in January, enabling hash-based signatures for transparent payments. Zcash's transparent payments publicly display transaction information, while shielded payments conceal the sender, receiver, and amount. This solution combines address rotation with private information retrieval, allowing wallets to change to a new address after each transaction and reducing the risk of public key exposure through WOTS-based hash alternative signatures. The Vizor wallet launched a private query feature this week, which users can enable in the settings for testing. Zakura's solution currently only covers Zcash's transparent payments, and the network has yet to confirm the activation time for the opcode. Ethereum researcher Justin Drake has warned that AI-driven mathematical breakthroughs could potentially crack related signatures in months rather than years; Vitalik Buterin believes that there is a possibility of cryptographic technology being compromised within the next two years.
