It’s clearly a demo of a tool, not a reference to use to the Bitcoin Whitepaper (for being partial in content).
I agree .
Too many things missing. I think the author should have clearly stated that some parts were ommited and that he created the animations.
I think it would also be better if he created new graphics and animations which could help total beginners to understand the concepts better. Soemthing like "beyond the whiepaper " instead of just a copy paste of some parts.
