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.
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.
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.
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
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!
Can someone please clarify if Ouroboros fails when the attacker places 3 red blocks on top of the longest chain? :/
Very good presentation.

Soooo... is Ouroboros unique in that aspect or does that two-dimensional random walk analysis applies to other POS blockchains?

Love the handwriting!
they get information is power and trust...
Impressive.!!
Yeh! Thats what I think.
ADA to the moon very soon. All this negativity comes from XRP lovers:) Ada best invest in 2018 !

GRABS POPCORN!
Other than the pronunciation ("Kai-yez", or "Kai-ey-ez", or something else) of your last name, I got the hang of everything presented.
