Advancements in quantum computing may eventually enable access to dormant Bitcoin wallets, including those of Bitcoin’s elusive creator, Satoshi Nakamoto, according to Tether CEO Paolo Ardoino. In a statement on February 8, Ardoino suggested that while quantum computing currently poses no immediate threat to Bitcoin’s cryptographic security, future developments could compromise inactive wallets lacking quantum-resistant protections.
Ardoino emphasized that Bitcoin’s existing cryptographic structures remain robust, with quantum computing still “very far from any meaningful risk of breaking Bitcoin cryptography.” However, he noted that as quantum technology progresses, wallets with lost keys or those belonging to deceased individuals could become vulnerable. This includes the estimated 1.1 million Bitcoins attributed to Satoshi Nakamoto, which have remained untouched since their creation.
The Tether CEO reassured active Bitcoin holders, stating that the cryptocurrency community is expected to adopt quantum-resistant addresses before quantum computing becomes a tangible threat. “All people alive will move Bitcoin into new quantum-resistant addresses,” Ardoino explained. This proactive approach aims to safeguard active wallets from potential future vulnerabilities.
Despite the potential for previously inaccessible Bitcoins to re-enter circulation, Ardoino underscored that Bitcoin’s fixed supply cap remains unchanged. “Only 21 million Bitcoin anyway. Nothing can change that. Not even quantum computing. That’s the real key important message,” he affirmed. This fixed supply is a fundamental aspect of Bitcoin’s design, intended to preserve its scarcity and value over time.
The discussion around quantum computing’s impact on Bitcoin security has gained momentum following technological advancements by major corporations. Google’s recent unveiling of its quantum processor, Willow, has sparked conversations about the timeline within which quantum computers might pose a genuine threat to current cryptographic systems. While these developments are noteworthy, experts generally agree that practical applications capable of compromising Bitcoin’s security are still years away.
Emin Gün Sirer, co-founder of Ava Labs, has also weighed in on the matter, highlighting that early Bitcoin transactions utilized a Pay-to-Public-Key format. This format exposes public keys, potentially making them susceptible to future quantum attacks. Sirer suggested that the Bitcoin community might need to consider measures such as freezing old P2PK-based holdings or setting deadlines for their usability to mitigate potential risks.
The identity of Satoshi Nakamoto remains one of the most enduring mysteries in the cryptocurrency world. Various theories and investigations have attempted to unmask the creator, but none have been conclusive. The potential unlocking of Satoshi’s Bitcoin holdings through quantum computing adds another layer of intrigue to this enigmatic figure’s legacy.
