I guess this is part 3. With part 1 introducing noname, a programming language inspired by rust that makes use zero-knowledge proofs to provide verifiable computation, part 2 going over a simple arithmetic example and part 3 going over custom types.

In this update, I showcase a new feature: functions, and go through the debug compilation of an example program to see if the implementation is sound (that it constrains what it is supposed to constrain). In this video I do something more: I optimize the implementation of assert_eq so that you can see a bit of the compiler internals. I also end the video abruptly, thinking I found a bug in the implementation. If you were an attentive student, you would have figured out that there was no bugs: doing things on constants does not create any gates.

You can play with the noname language here! And you can read the noname book as well.
