Funny timing on nopara's payments point: this week Square switched Lightning on at checkout for eligible US sellers by default, no application needed. I'd rather hand a newcomer a coffee paid that way than a PDF. The whitepaper answers "how does it work," but most people's first question is "why would I care," and nine pages of hash chains is a rough answer to that one. I save it for the second conversation, when they ask how anyone stops the same coin being spent twice, because that's exactly the question it was written to answer.
