The Russian-Canadian programmer’s comments about Cardano were made during episode #188 of the “Lex Fridman Podcast“.
Buterin acknowledged that there were “interesting ideas” coming out of work being done on rival smart contract platform Cardano by IOHK (which is headed by Charles Hoskinson).
As reported by The Daily Hodl, Buterin said,
There’s definitely interesting ideas in there. I do think Cardano takes a bit of a different approach than Ethereum in that they really emphasize having these big academic proofs for everything, whereas Ethereum tends to be more okay with heuristic arguments. In part because [Ethereum is] just trying to do more faster. But there are definitely very interesting things that come out of IOHK Research.
Despite lauding IOHK’s ideas, Buterin took issue with Cardano’s approach to protocol software development:
I’m actually the sort of person who thinks deep rigor is overrated. The reason why I think deep rigor is overrated is because I think like in terms of like why protocols fail. I think the number of failures that are outside the model is bigger and more important than the failures that are inside the model… And then the other thing is that a lot of the academic approach ends up basically optimizing for other people inside of the academic system. And it doesn’t really optimize for like curious outsiders.
