Cardano founder: BIP-361 is actually a hard fork and cannot save Satoshi Nakamoto's Bitcoin.

CoinFeed reported on April 17th, citing CoinDesk, that Cardano founder Charles Hoskinson stated that BIP-361, the Bitcoin quantum defense solution proposed by developers Jameson Lopp and others, was incorrectly labeled as a soft fork and requires a hard fork in practice, which conflicts with Bitcoin's culture of resisting hard forks. He pointed out that the zero-knowledge proof-based recovery mechanism in the solution cannot protect approximately 1.7 million early Bitcoins (including about 1 million held by Satoshi Nakamoto) because these tokens were created before the introduction of the BIP-39 mnemonic phrase standard in 2013, using the local key pool in the original Bitcoin wallet software instead of a recoverable mnemonic phrase seed, and therefore cannot provide the cryptographic credentials required for zero-knowledge proofs. If the proposal passes in its current form, these early tokens will be permanently frozen.
