Cryptographer Adam Back, known for his involvement in the Bitcoin white paper, believes quantum computing could expose the identity of Bitcoin’s pseudonymous creator, Satoshi Nakamoto. Back suggests this technology could force the community to either deprecate old addresses vulnerable to quantum attacks or allow their assets to be stolen if not moved to newer, quantum-resistant signatures. He anticipates a major shift in Bitcoin’s cryptography within the next 20 years, when quantum computers pose a more significant threat. Back believes this situation will force a choice between either allowing theft of funds from vulnerable addresses or freezing them to deprecate the signatures used for those transactions. While privacy advancements might provide solutions, their effectiveness in revealing Satoshi Nakamoto’s fate remains unclear. Some speculate that even if he were alive and still held private keys, he might choose to remain anonymous instead of moving his coins, as it could be a controversial decision for him to take.
