Here's hoping that my stock for D-Wave ends up being worth something.
Quantum computing seems super cool, but I've been a little skeptical of it actually ever yielding anything useful. I would love to be wrong, it seems neat, and I have read through a few books on the subject and played with simulators, so I'm not completely talking out of my ass here, but quantum as a whole has kind of felt like vaporware to me.
As I said, I have stock in D-Wave, obviously it would be in my best interest for quantum to end up as cool as it seems.
One thing I find rather amazing about all of this is the degree to which the Bitcoin community has tried, for years, to claim that quantum computers will be another other than a complete break.
Sure, it takes a pretty nice quantum computer or a pretty good algorithm or a degree of malice on the part of miners to break pay-to-script-hash if your wallet has the right properties, but that seems like a pretty weak excuse for the fact that the entire scheme is broken, completely, by QC.
Does there even exist a credible post-quantum proof protocol that could be used to “rescue” P2SH wallets?
Maybe it's a good time to start promoting my 5 year old, lightweight, hand-crafted, battle-tested, quantum-resistant blockchain: https://capitalisk.com/
It's about 5000 lines of custom code. Crypto signature library written from scratch.

I have NOT used it, but the idea is interesting.
