Bitcoin Faces a New Threat—Quantum Computing

[mendez]

A new proposal led by Jameson Lopp suggests freezing quantum-vulnerable Bitcoin to protect the network from future risks. The concern is that powerful quantum computers could one day break older cryptographic signatures, potentially exposing around 1.7 million BTC—including wallets believed to belong to Satoshi Nakamoto.

This proposal, part of BIP-361, aims to prevent attackers from stealing these funds by making them unspendable if they remain in outdated address formats. The idea is defensive: rather than allowing malicious actors to exploit vulnerabilities, the network would proactively secure itself before quantum technology becomes a real threat.

While quantum computing is still developing, the discussion highlights how long-term risks are already shaping Bitcoin’s future. Preparing for these scenarios early could be critical to maintaining trust and stability in the network.

~1.7m Bitcoin potentially exposed to quantum risk is not trivial, especially if large dormant wallets get targeted.
