Bitcoin's Quantum Risks and the Future of Cryptocurrency Security

As the cryptocurrency market continues to grow and evolve, concerns about its long-term security have become increasingly pressing. Alex Thorn, Head of Corporate Research at Galaxy Digital, has been studying the potential interactions between Bitcoin and quantum technologies.

In a recent assessment, Thorn highlighted one of the most sensitive issues in the Bitcoin ecosystem: the status of early coins believed to belong to Satoshi Nakamoto. These coins are largely held in P2PK (Pay-to-Public-Key) addresses, which could be vulnerable to tampering by malicious actors.

However, Thorn notes that these coins are distributed across approximately 22,000 separate addresses, each containing 50 $BTC. This suggests that a potential quantum attack would require targeting a large number of addresses rather than a single one, making it less likely to succeed.
