That makes sense. One of the questions concerning the process of future-proofing bitcoin
to me would be how to protect legacy addresses from a quantum attack, addresses where
the private keys may have been permanently lost.
Potential solutions:
1. Provide plenty of warning and time for people to move their bitcoin before permanently
"locking" legacy addresses. Of course, doing that would be highly controversial.
2. Do the above, but provide a means for the owner of a locked legacy address to prove
ownership by "signing" the bitcoin and restoring their access. I have no idea if that would even be possible.
3. Something else
If you want to seriously discuss this, it would be better to open a new topic in
Development & Technical Discussion as it would be off topic to continue this here. I've seen pieces of this discussion in many threads though.
Thanks I'll start another thread later.
