Quantum computers threaten Bitcoin’s ECDSA signatures, potentially exposing private keys via Shor’s algorithm. A hard fork to quantum-resistant cryptography is proposed, but Bitcoin’s decentralized governance could lead to paralysis. Simulations reveal challenges: achieving consensus among miners and nodes is slow, risking network splits. Vulnerable wallets, including Satoshi’s 1.1M BTC, face theft if public keys are exposed. Proposals like QRAMP suggest migration deadlines, yet non-upgraded nodes may fork, destabilizing the network. Governance disputes could delay upgrades, leaving Bitcoin exposed. Post-quantum algorithms (e.g., CRYSTALS-Dilithium) offer solutions, but implementation lags due to community resistance and technical complexity. This simulation underscores the urgent need for proactive governance to secure Bitcoin against quantum threats.
