At the 'Satoshi Spritz' event in Turin on April 18, 2025, Adam Back emphasized the necessity for Bitcoin holders to transition to quantum-resistant addresses due to the evolving threats posed by quantum computers.

While current quantum computers do not yet pose a significant risk to Bitcoin's cryptography, Back predicts that in about 20 years, they could become a credible threat, prompting holders to take action to protect their assets.

Back proposed a Taproot-based implementation for adopting quantum-resistant signatures, suggesting that Bitcoin should only make this transition when necessary, as many current solutions are either untested or resource-intensive.

Satoshi Nakamoto, who mined around 1 million BTC, has never accessed these funds, but the potential vulnerability to quantum attacks may lead to discussions about whether to move them.

Back highlighted a critical decision facing the Bitcoin community: to either deprecate old addresses vulnerable to quantum advancements or risk theft of funds, which could force Nakamoto to move their Bitcoin to avoid loss.

Despite the potential risks, some in the Bitcoin community remain skeptical that Nakamoto would move their coins even if alive, suggesting they would prefer to let the community decide on such a controversial action.

Adding to the intrigue, financial news editor Seán Murray recently linked Twitter co-founder Jack Dorsey to Nakamoto, citing circumstantial evidence and significant dates that coincide with Dorsey’s family birthdays.

Back indicated that the Bitcoin network will likely allow market forces to dictate whether users should move their funds, rather than freezing old addresses.

During the event, Back warned that as quantum computers advance, Bitcoin holders will need to be proactive in transitioning to quantum-resistant signature addresses to safeguard their investments.

Back also noted that future privacy upgrades in Bitcoin could complicate the visibility of coin movements, with research aimed at addressing quantum vulnerabilities while maintaining user privacy.

The potential for revealing Nakamoto's identity hinges on Bitcoin's future privacy features, which could allow for quantum upgrades without compromising anonymity.

An anonymous early Bitcoin miner expressed skepticism about Nakamoto's potential actions, suggesting that even if he is alive, he might prefer to let the community decide on moving the coins.
