<p dir="auto">The most vulnerable addresses are Pay-to-Public-Key addresses, known as P2PK, where the public key is directly visible on the blockchain. Once a public key is exposed, a quantum computer running Shor's algorithm could theoretically derive the corresponding private key and authorize transactions from that address. Bitcoin's older address formats, including those used in the earliest transactions on the network, are P2PK addresses. More modern Pay-to-Public-Key-Hash addresses are somewhat less immediately vulnerable because the public key is not revealed until the first outgoing transaction, giving the owner a window to move funds to a quantum-resistant address before the key can be attacked. Satoshi Nakamoto's estimated 1.1 million BTC sits across approximately 22,000 P2PK addresses of 50 BTC each, making it among the most discussed potential targets in the quantum vulnerability conversation.</p>
