OP_CAT? What?
Yep! Here's why. OP_CAT is very simple to understand, even if you don't know much about bitcoin Script or opcodes.
Concatenation, which is what the "CAT" in OP_CAT stands for, is computer science 101. It's a powerful building block with great versatility.
OP_CAT has some fun Satoshi lore and it's a gentle entry point into ongoing discussions about covenants and soft forks.

Special thank you to everyone that made this possible: bitcoin_devs (nprofile…uvtq) for sponsoring this zine, OpenSats (nprofile…5h0z) for covering the costs of physical printing and distribution for all my zines, and the OP_CAT BIP authors, Ethan Heilman and Armin (nprofile…g2rm) for the countless rounds of feedback and review that went into this. Thank you!
While I'm not able to write zines as fast as I'd like, they are still something I love to do and want to continue with. I have a big backlog of ideas I want to tackle but if there are any specific topics you'd like to see covered, drop a comment here.
Thanks everyone for your support. It means a lot. Enjoy!
