Cardano founder: BIP-361 is actually a hard fork and may freeze early BTC

ChainCatcher reports that Cardano founder Charles Hoskinson stated that Bitcoin's quantum defense proposal BIP-361 has been incorrectly described as a soft fork, while in reality, it is closer to a hard fork and cannot protect about 1.7 million early BTC generated before 2013, including approximately 1 million attributed to Satoshi Nakamoto.

He said that the zero-knowledge proof recovery scheme in the proposal relies on BIP-39 mnemonic phrases, whereas early wallets used different key generation methods and cannot provide the required proof, so related assets under the current plan may be permanently frozen. The report also notes that BIP-361 co-author Jameson Lopp described it as a rough contingency proposal rather than a final specification.
