A proposal to freeze dormant bitcoin, valued at over $440 billion, has sparked intense debate among industry experts, with some warning that such a move could trigger a catastrophic market repricing, while others argue that it is necessary to protect against the looming threat of quantum computing. The discussion centers around the estimated 5.6 million bitcoin that have been inactive for over a decade, posing a significant risk if quantum computers were to become powerful enough to crack their encryption.

Bitcoin developers and industry participants have been debating the best course of action, with some advocating for a 'freeze' on these tokens to prevent potential theft, while others argue that such a move would undermine the fundamental principles of the bitcoin network, including its decentralized and immutable nature. Proponents of the freeze, such as Jameson Lopp, a core Bitcoin developer, argue that it is necessary to protect the network from the existential threat posed by quantum computing, while others, like Samuel 'Chad' Patt, founder of Op Net, warn that freezing any coins, even 'lost' ones, would set a dangerous precedent and undermine the market's confidence in the asset. The debate has also drawn in other experts, such as Jason Fernandes, a market analyst, who believes that a successful quantum attack would have far more severe consequences than a freeze, and that the network's ability to survive such an attack is a more significant concern than the precedent set by a freeze. Meanwhile, Mati Greenspan, a self-described maximalist and market analyst, argues that if quantum computers were to crack early Bitcoin wallets, it would trigger the largest bug bounty in human history, rather than a freeze or rollback.

The proposal to freeze dormant bitcoin has been put forward in the form of Bitcoin Improvement Proposal 361 (BIP-361), which contemplates phasing out bitcoin's current cryptographic signatures and potentially freezing assets that fail to migrate. However, not all experts agree that a freeze is the best solution, with some arguing that it would require a contentious hard fork, violating the network's decentralized ethos, and that better alternatives, such as improved tooling and voluntary migration, should be explored instead. Ultimately, the decision on how to address the quantum threat will have significant implications for the future of the bitcoin network and its users.
