[Zcash Expected to Introduce Quantum-Resistant Signature Opcode in January, Vizor Wallet Launches Private Query Feature] Odaily Planet Daily News: The Zcash full-node development team Zakura stated that the network is expected to introduce a quantum-resistant signature opcode in January, enabling hash-based signatures for transparent transactions. Zcash's transparent transactions publicly display transaction information, while shielded transactions hide the sender, receiver, and amount. This solution combines address rotation with private information retrieval, allowing wallets to generate a new address after each transaction and reduce public key exposure risk through WOTS hash-based backup 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 transparent transactions, 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 there is a possibility of cryptographic technology being compromised within the next two years.
