In this talk, Andreas introduces newcomers to the emerging scientific speciality of “forkology,” or the study of forks, how blockchain ecosystems change over time, and the game theory of competing consensus models. He covers not only the various types of forks but the agents involved in consensus evolution, grappling in this crazy new world where the traditional menus will no longer do.

This talk took place on June 6th 2017 at a joint meet-up with Blockchain Professionals, BitcoinSYD and SydEthereum in Sydney, Australia: https://antonopoulos.com/event/blockchain-professionals-sydney/
