Post-Quantum Cryptography

Cryptographer Filippo Valsorda has published a guide to correct answers on post-quantum cryptography, laying out what practitioners should actually adopt as quantum-resistant standards mature. The piece addresses common confusion around migrating from classical algorithms to post-quantum ones, such as ML-KEM and signature schemes, and is being shared widely among security engineers discussing how and when to future-proof systems against quantum attacks.

Ethereum co-founder Vitalik Buterin has endorsed calls for the crypto industry to enter 'bunker mode', a defensive posture urged by Ethereum researcher Justin Drake, who warns that rapid advances in AI-driven mathematics could break current wallet cryptography within months. The warning has sparked debate about how urgently blockchain projects should prepare for post-quantum and AI-accelerated security threats.

A new messaging app called Veil has been launched, pitched as a zero-knowledge messenger that uses post-quantum encryption so that even the operator cannot read users' messages. The launch is drawing attention from developers debating how the architecture works in practice and whether post-quantum cryptography is ready for consumer messaging.

PowerDNS has published work on preparing DNSSEC for post-quantum cryptography, addressing how the domain name system's security layer can adopt quantum-resistant signatures. The post is drawing attention among developers and security engineers interested in how core internet infrastructure will handle the eventual threat quantum computers pose to current cryptographic schemes.
