AdamBack: Quantum computing threat still needs decades, BTC post-quantum signature upgrade still has plenty of time

Wu learned that Adam Back, the founder of Blockstream, tweeted that the main purpose of implementing post-quantum signatures like Winternitz in BTC is to eliminate quantum fear for traders, and believes that post-quantum signatures may not be relevant for the next decade or even more. The comments also mentioned the migration process, which includes activating new algorithms, disabling old algorithms, creating new secrets and transferring funds from old addresses to new addresses. At the same time, it was suggested what would happen if someone did not complete the third step before entering the post-quantum era. Adam Back said that even if the upgrade signature upgrade is implemented, there is plenty of time to complete the migration. The progress of quantum computers is very, very slow, with a difference of five orders of magnitude. Satoshi Nakamoto’s ability to handle it in a timely manner and the situation where funds were not transferred due to lost secret keys were also discussed, which may cause changes in the total supply of BTC.
