Leading Bitcoin Developer Jameson Lopp Advocates for Freezing 5.6 Million Dormant BTC to Prevent Quantum Hacking

According to Jameson Lopp, a prominent Bitcoin core developer, it would be preferable to freeze the estimated 5.6 million lost or dormant bitcoin rather than risk them being seized by future quantum hackers. In an interview with CoinDesk, Lopp stated that he does not want to restrict anyone's access to their bitcoin but believes that removing inactive tokens from potential circulation might be a safer option for the network. Lopp emphasized that his comments are speculative, considering a potential future threat. He expressed that he would rather see lost or dormant coins removed from the reach of potential attackers than have them fall into the hands of an entity that may not prioritize the ecosystem's well-being. This discussion follows the release of BIP-361, a proposal exploring the possibility of phasing out Bitcoin's current cryptographic signatures and invalidating transactions from quantum-vulnerable wallets over time. The value of the dormant tokens in question is approximately $420 billion at current prices. Lopp later clarified on social media that he does not support the proposal and hopes it will never be necessary, describing it as a rough idea for a contingency plan rather than a finalized specification. Lopp has previously expressed concerns about quantum recovery, suggesting it could reward technological superiority over productive participation in the network. He views quantum miners as entities that do not contribute to the system, instead exploiting it for their gain. Approximately 28% of all bitcoin, or around 5.6 million tokens, has remained inactive for over a decade, and Lopp, along with other analysts, considers it likely that these coins are lost forever. If recovered through quantum computing, this amount could introduce significant market volatility and undermine confidence in the original cryptocurrency network. The proposal has sparked intense debate within the community, with Lopp framing the idea as a means to encourage users to upgrade their wallets before any real threat emerges. He stressed that the goal is not to freeze anyone's bitcoin but to incentivize the ecosystem to upgrade, as people tend to procrastinate. Any changes would require consensus across the decentralized network, and while there is no formal voting process, similar upgrades have historically required overwhelming support from miners to activate. The potential risks include not only market instability but also the erosion of trust in the largest cryptocurrency. Lopp believes that even without a massive market dump, credible evidence of the ability to recover lost or vulnerable coins using a quantum computer could trigger a significant market panic, prompting rational holders to exit the system until the blockchain is secured against such threats. The debate highlights a growing divide within the community, pitting Bitcoin's promise of immutable and censorship-resistant ownership against the need to protect the network from potential future threats. Market analyst Mati Greenspan views the debate as more philosophical than technological, questioning how the Bitcoin community should handle vulnerable coins. Greenspan argues that freezing dormant bitcoin accounts would mark a significant departure from Bitcoin's core principles, introducing a precedent of intervention that many consider more dangerous than the threat itself. Others, like Leo Fan, founder of Cysic, argue that freezing dormant BTC accounts risks undermining Bitcoin's foundational guarantees, as ownership would become conditional and having keys would no longer guarantee the ability to spend, thus weakening Bitcoin's promise of 'unstoppable money'.
