EU financial watchdogs warn quantum computing poses imminent threat to blockchain encryption

EU financial watchdogs warn that advances in quantum computing could eventually break the cryptographic systems securing blockchains, including Bitcoin. While a practical quantum attack is not currently available, the threat requires developers and institutions to begin planning migration to quantum-resistant encryption. The key implication for Bitcoin is that its long-term security will depend on timely protocol upgrades and user adoption of post-quantum safeguards.
