I remember having way too much fun writing this back in 2017 when I made the Bitcoin explainer. If someone describes a cryptographic protocol as having "256-bit security", what does that really mean?

Would you consider doing more, similar videos? The one you did on bitcoin has been the most valuable video on the topic to this day.

For Bitcoin in particular this is misleading. The keys have 256 bits of "classical security" but they require barely 10^8 operations on the first gen of large quantum computers being built.

One of the best video of yours. Not sure if you are interested in explaining other technology of crypto other than PoW. That would be amazing to see. There is very little out there which explains math behind it.
