Finished!
Congratulations everyone, we’ve completed the book! Next we’re on to a hackergarden in a few weeks with a Go bitcoin repo that has some issues we might try to address. Also I’ll be reading about Sapio as a side reading with perhaps some ad-hoc meetups. (I have not taken a position on BIP-119 yet. I’d like to understand it better first.)
Other topics, among others, we plan to look at - taproot, lightning network (the book), and drivechains

Extra notes from January 27
p is the order of the finite field
n is the order of the cycle of points from the generator point G, such that n*G=0
Both p and n are prime.
Both p and n are very close to 2256 , and n < p
Integers in the range [0, 2256) - 1] can be stored in 32 bytes and can be displayed with 64 hex characters
So, too, can integers in the range [0, p] or [0, n]
