Odaily Planet Daily reported that Casa's CTO and co-founder Jameson Lopp proposed a Bitcoin improvement plan on Tuesday aimed at addressing the potential threat posed by quantum computers to the Bitcoin network. This proposal was co-authored by six developers and plans to phase out quantum-vulnerable address types in three stages. According to recent research by Deloitte, approximately 25% of Bitcoin is currently at risk from quantum computing, including an estimated 1 million Bitcoins believed to belong to Bitcoin's founder, Satoshi Nakamoto. Experts are concerned that as quantum computing technology advances, the private keys of these old wallets could be reverse-engineered within the next decade. The proposal will prohibit sending funds to quantum-vulnerable addresses and freeze the Bitcoins of these addresses over a five-year period, while encouraging users to adopt 'post-quantum' Bitcoin address types. The authors of the proposal emphasized: 'Bitcoin has never faced a survival threat to its cryptographic foundation; a successful quantum attack would cause significant economic turmoil and damage to the entire ecosystem.'
