Since the computing power of quantum computing is still insufficient to crack Bitcoin's hash and signature mechanisms, its security is currently not at risk. However, Satoshi Nakamoto's one million Bitcoins, which use the early public key format (P2PK), are at risk of being breached by quantum computing. The community can respond to future challenges by introducing quantum-resistant encryption or hard ...
