We are joined by Charles Hoskinson, who played an early role in developing Ethereum and BitShares, and is currently the CEO of IOHK. IOHK is an engineering company that undertakes cryptocurrency research, contributes development efforts to the Ethereum Classic ecosystem, and is spearheading the release of Cardano – a third generation blockchain protocol. IOHK has made the news recently after the publication of fundamental research papers on the Proofs of Proof of Work and the Ourobouros PoS algorithm, and its recruitment of highly rated academics.

Topics discussed in this episode:
– IOHK's role in the Ethereum Classic ecosystem, and how Ethereum Classic differs from Cardano
– Cardano as a ""third generation blockchain"" and what this means
– Governance system of Cardano and the challenges behind developing a decentralized governance system
– Ourobouros PoS algorithm – why was it developed and what's special about it
– Ourobouros Genesis: how full nodes can be bootstrapped without requiring checkpoints
– Cardano's bet on K framework for smart contract execution

    • not peer reviewed (secure) like ADA. Also I think delayed or cancelled. May be just PR stunt

  1. Thank you for this interview…a few words: Charles Hoskinson is the CEO of IOHK. Cardano can’t have a CEO because it’s a decentralized protocol 🙂

  2. 31:00 min. So I hope the next question is: How is the Bitcoin network a barrier to change Charles?

    • Well um – I guess Charles just gets to drop that “Bitcoin network is a barrier” bomb shell, you guys cut to an ad and on we go. Poor form I say. I have watched this show and respected you guys for years. Keep on it lads…???

    • It wasn’t really a bomb being dropped, the whole 5+ minutes of the conversation before 31:00 was a lead up to the btc network example. the interviewer was asking about a rich get richer scheme vs a level playing field and Charles brought up the obsolete rigs being sold, high startup cost and cheap power… the “Bitcoin network is a barrier”.

  3. Sunny was great. His understanding and questions were impressive. Definitely bring him back!

  4. Charles has earned back my respect. He’s a lot more intelligent than I originally thought when I made my initial video on him and Cardano.

  5. very high hopes for this project! That coffee deal with Ethiopia and all the outreach proves that this project actually believes in this movement.

  6. I would like to know how much they will give to verify the transactions of POS for having it in the wallet and how much would be the minimum for the participation, thanks
