Introducing Blockchain with LISP: Implement and Extend Blockchains with the Racket Language

This is a great introduction to blockchain. It's about 20 pages of introduction to blockchain. 20 pages of introduction to the programming language Racket and then probably about 60 pages of blockchain implementation.The code examples have all worked so far and the Racket documentation is very good.I think it really helps when trying to understand blockchain to implement some of it yourself (even if at a toy level). I think I'll remember how a blockchain system works much better than I would have otherwise.

Finally a novice-to-intermediate Lisp book that you can self-study without hitting a wall. OK, I hit one wall, but had neglected to refer to the Racket tutorial in the second chapter, and figured things out easily once I did. I haven't had this much fun since the cartoon section of Land of Lisp. And running and annotating the code gives you amazing flow. I used box comments (Racket > Comment out with a box) to place some of the book's comments and the REPL/instructions into the relevant definitions/files along with the code. I'm about 3/4 through and already this book is going in my collection next to The Little Schemer in the underpopulated great-computer-books-I-eagerly-worked-through-and-nearly-finished section.
