Cardano founder Charles Hoskinson stated that BIP-361, proposed for the Bitcoin quantum computing risk, is mistakenly called a soft fork, when in fact it would require a hard fork to implement, which conflicts with Bitcoin's long-standing development culture of opposing hard forks; he believes the scheme relies on a zero-knowledge recovery mechanism based on BIP-39 mnemonic words, which cannot cover approximately 1.7 million early Bitcoins (including about 1 million believed to belong to Satoshi Nakamoto), because these assets were created before 2013 and lack the corresponding mnemonic structure. If executed according to the current plan, these assets could be permanently frozen. (CoinDesk)
