Community Technology by Karl Hess.
I knew of him as a famous libertarian, and I read his stuff 30 years ago, but this book was recommended to me by @David_Boethia in response to my Bitcoin Pioneers post. It's an account of Hess's attempt to organize a self suppoting libertarian community in the Adams Morgan section of Washington DC. I'm about half way through, and I'm really enjoying it. His ideas can be applied to creating local bitcoin circular economies.
Katz, Lindell: Introduction to Modern Cryptography
I've read Katz, Lindell: Introduction to Cryptography years ago and thought this one was like an alternative edition, but it isn't. Really nerdy math stuff. :D
One I want to start is The Blocksize Wars, but I've got a lot of other stuff rn like Meditations and Change: How to Make Big Things Happen by Damon Centola
路 "The Impeachment of Abraham Lincoln" by Stephen Carter, for the first time
路 "The Meaning Of It All", by Richard Feynman, for the second time
路 "Getting Things Done" by David Allen, which I re-read every couple of years
I usually have a few books started, I'm on the Bitcoin Standard right now but when I finish I'll go back to A History of Force, about the humanity's historical trend against the use of force.
