A minor point about the podcast: Alex Hern misunderstood the process that Craig Wright, the self-processed founder of bitcoin (Satoshi Nakamoto), needed to go through to prove that he was indeed Satoshi. Alex says that Craig needed to "move the first bitcoin ever created", while in reality Craig needed to sign a message with a private key. Because of how bitcoin is made, the very first bitcoin block (the "genesis block") cannot be spent [1].
