I created a short video and slide deck to help illustrate how a blockchain works. This is not about Bitcoin, but is intended to help people who aren’t as experienced with Merkle trees understand that the idea of a blockchain is to be able to independently verify where and when a thing happened without being able to go back and alter it to make something else have happened instead.

That’s an oeuf for now.
