Hey Toby,
Great question. The tldr is that none of the funds are vulnerable in this circumstance:
D) No sats!
When Bob sends 6K of the original10K, the remaining ~4K is actually transferred to a new (change) address. It's no longer in the original 1st receival address, but is instead in the 1st change address!
And the second transaction of 100K is received to the 2nd receival address, which is separate from all of the above.
The real problem is when there are multiple receives to the same address, and at least one spend.
So your example, if the 100K was instead received to the original (1st) receival address (where the 10K was first received), then 100K would be vulnerable as the keys were exposed on the spend of 6K.
Hope this clarifies?
Very interesting episode about Quantum computing and threats to Bitcoin! I knew I shouldnât reuse addresses, but never realised the risks related to XPUBsâŠ

I think I will need to clarify the xpub situation, left it a bit too ambiguous
Had a great chat with nostr:npub1r8l06leee9kjlam0slmky7h8j9zme9ca32erypgqtyu6t2gnhshs3jx5dk along with my co-author Clara in talking about Quantum Computing and what it means for Bitcoin.
(Now I see why a good mic is essentialâŠ)
Maybe you could create your own Kagi lens?

If you didnât make it through the original report this is a nice and short summary đ€
Nah, not even a wallet setup on Fountain.
But I listened to the ep (first one)
Really need to get better at shilling this :)

Your lungs will start to feel so âstrongâwhen you wake up. Itâs a weird feeling but youâll know what I mean..
Did you use MediaMTX?
A few years ago it was my go to show after coming home from a night out.
Thereâs something for parents in almost every episode.
And 7 mins per episode was perfect to continue watching or call it a night.
Let me know if you tear up on âThe Signâ or âCricketâ!!

Moving Forward â©
This report shows that the Bitcoin community has long been aware of the threat posed by CRQCs and has been debating and discussing Bitcoinâs response for some time. However, the window for careful, deliberate action exists today, and will narrow as quantum computing advances. This makes proactive preparation not merely prudent, but essential for Bitcoin's long-term survival.
