I haven't really understood the entire concept of this proposal, but I will do a further research while less busy, and thanks for sharing this here.

The Bitcoin-Quantum computing attack has been a discussion for sometime now, and I never expected a sudden proposal at this early stage because we haven't really see the effect of quantum computing attacks, as a primary target to any form of technology. I know that some of these big companies are investing heavily on it, and their progress so far isn't fully disclosed to the public. But it is good that a proposal was introduced at this early stage, so that proper remodification and adjustment can be done before fully implementing, if still necessary.


It all depends on their approach of attack.
They might decide to go for dormant wallets aside that of Satoshi, just to test. Because a direct attempt on Satoshi's old wallets might escalate things, and who knows what will happen afterwards.
