Ledger CTO Charles Guillemet stated that Bitcoin currently does not face an imminent threat from quantum computing. The real challenge lies in completing the quantum-resistant migration, which could take years. He believes that SHRINCS is one of the more serious post-quantum signature schemes specifically designed for Bitcoin. It is based on SHA-256 and combines stateful signature paths with stateless fallback options. However, SHRINCS introduces new state management risks to the wallet ecosystem. If a one-time signature slot is reused, it could lead to stolen funds. Additionally, some existing BIP32 derivation and threshold signature capabilities may not be directly retained. Compared to choosing a signature algorithm, upgrading wallets, migrating existing BTC, and dealing with long-dormant coins might prove to be even more challenging. https://(wublock123.com)/news/news-68540
