Bitcoin Developer Proposes Freezing $420 Billion in Dormant BTC to Counter Quantum Threat

Bitcoin core developer Jameson Lopp has proposed a contingency plan to freeze approximately 5.6 million BTC—roughly 28% of the total supply—to protect the network from potential quantum computing attacks. The proposal, outlined in BIP-361, explores phasing out current cryptographic signatures and invalidating transactions from wallets that fail to migrate to quantum-resistant standards. Lopp argues that removing these dormant tokens from potential circulation is a necessary safeguard. He contends that it is preferable to freeze lost coins than to allow 'quantum vampires'—entities with technological supremacy—to seize assets and dump them into the market, which would reward hacking over productive participation. At current market prices, the dormant assets in question are valued at approximately $420 billion. Lopp notes that these coins have not moved in over a decade and are widely considered lost by most analysts. While the proposal is in its early stages and requires decentralized consensus to implement, Lopp warns that the mere evidence of quantum recovery capabilities could trigger immediate market panic. He suggests that rational holders would likely exit the system until the blockchain is proven secure against such threats. The debate underscores a fundamental rift within the Bitcoin community, pitting the long-standing promise of immutable, censorship-resistant ownership against the pragmatic need to defend the ecosystem from an existential technological shock.
