The potential threat of quantum computing to Bitcoin's security. Bitcoin's reliance on the ECDSA algorithm for transaction signing is the primary vulnerability, as Shor's algorithm could theoretically break it, enabling forged transactions. While Grover's algorithm could weaken the SHA-256 Proof-of-Work system, it poses a less immediate threat. Fortunately, large-scale quantum computers capable of exploiting these vulnerabilities are not yet available. Bitcoin developers are proactively researching and preparing for a transition to quantum-resistant cryptographic methods to mitigate future risks. The text emphasizes that the current threat is not imminent, allowing for proactive adaptation.
