i like seeing a bit of the raw, low-level protocol first. a few curl examples are perfect for understanding what’s really happening under the hood. once i get that, i'm happy to use a library to handle all the edge cases.

but starting with a library tutorial makes me wonder how many stacks of turtles are being hidden. if i can see the turtles upfront, i'll appreciate what the library does for me -- and i'll have a better sense of how to debug when things break.

everything we need to authenticate the msg should exist in the msg. sig => timestamp, hash
