TechFlow reported on January 12 that, according to CoinDesk, post-quantum cryptography expert BTQ Technologies has launched an open-permission testnet called "Bitcoin Quantum," aimed at addressing the potential threat quantum computing poses to the Bitcoin network. This testnet adopts the lattice-based signature algorithm ML-DSA (commonly known as Dilithium), a post-quantum algorithm standardized by the National Institute of Standards and Technology (NIST) in August 2024.
Chris Tam, Partnership Lead at BTQ Technologies, stated that quantum computing threatens Bitcoin through two main attack vectors: deriving private keys from public keys and attacking the proof-of-work algorithm. Although post-quantum algorithms maintain the same interface, their underlying mathematical foundations are significantly more robust, enabling resistance against quantum computing attacks.
