It is essential to precisely understand why quantum computing poses a threat to blockchain. As the quoted text rightly explains, other systems such as banks are equally vulnerable to quantum computing. However, new quantum-resistant algorithms are already being standardized, and centralized systems can simply replace their current algorithms when the time comes. Even if a hack occurs due to quantum computing, previous transactions can be reversed. In the case of Bitcoin, users must manually replace their private keys with new quantum-resistant keys. This means there is no solution for Satoshi’s wallet or any lost wallets. Should we freeze or burn all lost coins, including Satoshi’s? That would contradict Bitcoin’s core value—the principle that no one can interfere with another person’s assets. In fact, quantum computing powerful enough to target known addresses (e.g., Satoshi’s wallet) and crack them within days is not as far off as one might think (we must transition to quantum-resistant address systems no later than 2030).
