Keynote at GeekCamp Singapore 2012 (http://geekcamp.sg/schedule/view_schedule/2012)
Fiat currencies and Bitcoin are valuable, despite being physically intangible, unlike gold is. However, while fiat currencies rely on government regulations to maintain their values and security, Bitcoin requires none of the authority interventions or appointed watchdogs, all thanks to cryptography.
This talk covers basic and intermediate topics on how cryptology aids in the working of Bitcoin P2P network.
