I really liked this video by 3Blue1Brown explaining how blockchain works: https://youtube.com/watch?v=bBC-nXj3Ng4 https://youtube.com/watch?v=bBC-nXj3Ng4 Things that I didn't realize until I watched the video: * "Mining" bitcoin means processing transactions for other people. Miners do time consuming operations to process transactions. I had never heard of 3Blue1Brown before someone showed me that video, but he has a bunch of other good math videos. I liked the one about pi showing up in weird places.
