I wanted to post this video to the blog as we mentioned bitcoin in our previous class and because it delves into the infrastructure of the exchange protocol (labor, computing, electricity & heat, etc.).
For anyone interested in learning more about bitcoin from a technical standpoint, I highly recommend with the following topics: public key cryptography, proof of work, and the public ledger, also known as the blockchain.
(If you ask me about it, I will probably bore you for hours.)
