- In this video, Prof. Aggelos Kiayias explains the research behind Ouroboros, the blockchain protocol underpinning Cardano, a top ten cryptocurrency by market capitalization.
Developing Cardano is no small feat. There is no other project that has ever been built to these parameters, combining peer reviewed cryptographic research with an implementation in highly secure Haskell code. This is not the copy and paste code seen in so many other blockchains. Instead, Cardano was designed with input from a large global team including leading experts and professors in the fields of computer programming languages, network design and cryptography. We are extremely proud of Cardano, which required a months-long meticulous and painstaking development process by our talented engineers.
Prof Aggelos Kiayias is the Chair in Cyber Security and Privacy at the University of Edinburgh. His research interests are in computer security, information security, applied cryptography and foundations of cryptography with a particular emphasis in blockchain technologies and distributed systems, e-voting and secure multiparty protocols as well as privacy and identity management. He joins IOHK as chief scientist through a long-term consulting agreement between IOHK and the University of Edinburgh, UK, where he is based and continues to do research and teach courses in cyber security and cryptography. Prof Kiayias is also Professor in Residence (gratis) at the University of Connecticut, USA, and Associate Professor of Cryptography and Security (on leave) at the National and Kapodistrian University of Athens, Greece.
Prof Kiayias’s cyber security research over the years has been funded by the Horizon 2020 programme (EU), the European Research Council (EU), the General Secretariat for Research and Technology (Greece), the National Science Foundation (USA), the Department of Homeland Security (USA), and the National Institute of Standards and Technology (USA). He has received an ERC Starting Grant, a Marie Curie fellowship, an NSF Career Award, and a Fulbright Fellowship. He holds a Ph.D. from the City University of New York and he is a graduate of the Department of Mathematics at the University of Athens. He has more than 100 publications in journals and conference proceedings in the area.

Prof. Aggelos Kiayias and the Cardano team will win a Nobel Prize in under 20 years.
Great talk Prof. Kiayias, thank you!
Greek proud, bravo...!
My favorite team thus far
In case anyone wonders what he is his referring to when he said "with respect to the last block that was issued by an honest party" @ 33:58, he is referring to the last block within the execution segment, and *not* in a given fork/chain. This explains why, in the ideal execution segment example, the reach for all _times_ except for one are negative.
Amazing. Really well done. I'm so excited to see where Cardano will go.
Thanks Aggelos. I learnt a lot.
Amazing Project :D
Great work, Thank you for the video!
Very good presentation.
Can someone please clarify if Ouroboros fails when the attacker places 3 red blocks on top of the longest chain? :/
Love the handwriting!
Impressive.!!
they get information is power and trust...
Yeh! Thats what I think.
Other than the pronunciation ("Kai-yez", or "Kai-ey-ez", or something else) of your last name, I got the hang of everything presented.
Soooo... is Ouroboros unique in that aspect or does that two-dimensional random walk analysis applies to other POS blockchains?
The point is that other PoS blockchains did not derive their protocol from mathematical requirements. They just coded (in an imperative language) how they would like to protocol to behave. It is a textbook tortoise and the hare example. Cardano is putting "process" first, using a functional language instead of an imperative one, and avoiding assumptions in their implementation. This is similar to how an aerospace company would build an avionics system. Blockchain and avionics both share the safety critical aspect because blochains are immutable (irreversible) the same way that human casualties are irreversible.
GRABS POPCORN!
ADA to the moon very soon. All this negativity comes from XRP lovers:) Ada best invest in 2018 !
I'd advise invest in Both. XRP is mostly for banking so it had different goals from cardano. Right now my portfolio is Eth, Lightcoin, cardano and XRP. Warning please dont invest anything in worthless inapp tokens.
The only people I see down playing ADA is EOS and Ethereum supporters. Never heard xrp lovers saying anything. They are two different systems. EOS and ethereum though, compete with ADA so it will be interesting to see what happens. Personally, I support ADA. Fantastic team doing diligent work.
