According to BlockBeats, on April 16th, Bitcoin Core developer Jameson Lopp recently stated that rather than allowing quantum computing attackers to steal long-dormant Bitcoins in the future, it would be better to freeze them. Approximately 5.6 million BTC (about 28% of the total supply) have not moved for over a decade and are likely permanently lost, with a value of approximately $420 billion. If these dormant coins were cracked by quantum computers and entered the market, it could trigger severe volatility and market panic, even damaging confidence in the Bitcoin network. Lopp emphasized that this is not the outcome he desires, but rather a stopgap measure to combat potential existential threats; he prefers to prevent these "lost" coins from being exploited by attackers.
Loop co-sponsored BIP-361, which aims to phase out the current quantum-fragile signature mechanism and encourage users to upgrade their wallets by invalidating transactions in unmigrated wallets. The idea is still in its early stages, and Loop himself has stated that he "dislikes" the proposal and hopes it will never need to be implemented, but believes that in the face of quantum threats, overall network security is more important than strict immutability principles.
