XGate said on Tuesday its post-quantum cryptography-based hybrid cryptographic module has received KCMVP certification from South Korea\'s National Intelligence Service. KCMVP is a state verification scheme for cryptographic performance in security products introduced to the government and public institutions. XGate said it has now secured certification for both hardware-based QRNG and software-based PQC. The company plans to accelerate efforts to capture markets requiring top-level security, including defense, public sector and finance.

Cardano founder Charles Hoskinson criticised a Bitcoin developer proposal for quantum-computing defence, calling it effectively a hard fork. He said the plan could fail to protect early Bitcoin created before the BIP-39 seed-phrase standard was introduced in 2013, including coins believed to belong to Satoshi Nakamoto. Bitcoin Core developer Jameson Lopp, a co-proposer, said the idea was for emergencies and hoped it would not be adopted.
