Bitcoin faces a significant security threat from the advancement of quantum computing, which could compromise the 1.1 million bitcoins stored in Satoshi Nakamoto's wallet, valued at approximately $10 billion. These bitcoins, representing about 25% of the circulating supply, are vulnerable due to outdated encryption keys susceptible to quantum attacks. Bitcoin's security relies on the Elliptic Curve Digital Signature Algorithm (ECDSA), which is currently secure against traditional computers but could be broken by quantum computers in minutes or hours. The timeline for quantum computing's maturity is uncertain, ranging from a few years to potentially never. However, the threat necessitates proactive migration to Post-Quantum Cryptography (PQC) to prevent catastrophic breaches. If quantum computers emerge before Bitcoin transitions to PQC, billions of dollars in public keys could be exposed, leading to massive theft and a destructive price crash. The urgency for strategic action is critical, requiring coordination among miners, trading platforms, and wallet providers to implement post-quantum signature algorithms before quantum computers become a reality.
