Bitcoin News said in a post on X that China launched a next-generation commercial cryptography program in 2025 to develop and evaluate standards designed to withstand future quantum computers. During a review of candidate algorithms, independent researcher @mjos_crypto said several proposed schemes showed critical weaknesses. The issues cited included publicly reproducible private keys, hash collisions that could be constructed easily, and signature implementations that accepted invalid signatures. The post tied those findings to the broader debate around Bitcoin’s long-term quantum readiness. Bitcoin currently relies on established elliptic curve cryptography, which has been broadly tested and remains part of its security model today. At the same time, the report noted that moving too early to post-quantum systems that have not been tested enough could introduce vulnerabilities before any practical quantum threat arrives. The episode highlights a core tension in crypto security planning: preparing for a future risk without weakening current systems through immature replacements.

Independent researcher @mjos_crypto, after analyzing candidate algorithms in the program, said several proposed schemes contained critical flaws. The problems listed included publicly reproducible private keys, hash collisions that could be constructed easily, and signature implementations that accepted invalid signatures.
Bitcoin’s quantum security debate remains unsettled
The post said Bitcoin currently relies on established elliptic curve cryptography. Future quantum computers may challenge that security model, but adopting under-tested post-quantum cryptography too early could introduce new weaknesses before any quantum threat becomes practical.
