Hilariously written and genuinely high quality information. Too many cryptography tutorials start by rehearsing the precise definition of a group, and formulas for elliptic curve arithmetic etc. only to conclude with like two paragraphs on the actual crypto. It's pretty refreshing to see things like "How points addition + is defined is not our concern, what we care is that (E, +) forms a group" lmao because that's exactly right.
