That quote actually comes from an early technical conversation I was having about proof-of-sacrifice. Specifically, a conversation lamenting the fact that we kept on inventing neat tricks faster than we could actually use them - by "world's leading expert" I was making fun of the fact that I was technically the world's leading expert in something relatively simple and obvious to Bitcoin experts... yet even I hadn't actually put the technique into practice in a production application.

If you freeze-frame the film at the right point and actually read the full conversation, this is obvious. I don't have it handy. But some people posted screenshots on Twitter (which HBO may have taken down via DMCA... they were getting video clips taken down too).

These days some stuff actually uses proof-of-sacrifice in production. The best example I think being Joinmarket: https://github.com/JoinMarket-Org/joinmarket-clientserver/bl...
