Time Runs Out for Bitcoin to Mitigate Quantum Computing Threat, Putting 6.9 Million BTC at Risk

While not all aspects of Bitcoin are vulnerable to quantum computing, the ownership of coins is at significant risk. Quantum computers can potentially break the cryptographic protections of Bitcoin wallets, which could lead to the theft of approximately 6.9 million BTC, including those owned by Bitcoin's creator, Satoshi Nakamoto. The current threat stems from the fact that many Bitcoin wallets have publicly visible keys, making them susceptible to quantum attacks. The recent Taproot upgrade has also expanded the problem by publishing keys for any Bitcoin spent since its activation. Although some proposals, such as BIP-360 and a detection system by BitMEX Research, aim to address the issue, they lack broad support from Bitcoin's core developers. The lack of a formal governance process and central authority in Bitcoin makes it more challenging to implement effective solutions compared to other blockchains like Ethereum, which has a well-structured plan to migrate to quantum-resistant cryptography. As the timeline for potential quantum attacks shortens, the question remains whether Bitcoin can coordinate a significant security upgrade before it's too late.
