Kostas Chalkias and Catherine sit down with beer and discuss how cryptography is used in and outside of the blockchain world. Catherine learns about the origins of cryptography, the Enigma machines, how cryptographers can hack into your computers, why it's so important for blockchain and more! **** FYI Catherine has now changed all of her passwords and has disconnected from all random WiFi networks. Thanks for the advice Kostas!
