This is part two in my basic visual introduction to the concepts behind a blockchain. We build on the concepts from the previous video and introduce public, private key pairs and signing using an interactive web demo. If you missed it, part 1 is here: If you are interested in playing with this on your own, it is available online at: The code that runs this demo is also on GitHub: If you want to know more about how public key cryptography works, see the Wikipedia page on it: The details of how public keys relate to private keys are hard to summarize, but it has to do with Euler s theorem. Basically, using Euler s theorem there is some math you can do to a number given some parameters (which I ll call the public key) which allows someone with some other parameters (whi
