A Beginner's Guide to Zero Knowledge Proofs (ZK Proofs Explained)

What are ZK (Zero Knowledge) Proofs? In this video, we explore the basics of ZK proofs, their potential use cases, and compare the different kinds of ZK proofs used in blockchain, such as ZK-SNARKs and ZK-STARKs.

Your videos are on another level. I was always looking for a channel like yours. Please continue the good work.

great video jarrod!

[@sayandcode]

Loved it

[@tobiassjoholm9325]

Great

So is there actually a way to use ZK tech to prove info from my driver's license without revealing it? That would be a great use case that seemed to somehow morph into an unrelated example. Can Polygon ZK somehow give us that? Can I pay $10 each time I get a new driver's license and universally have that thing?

Ok, this is video #3 that I have watched on ZK proofs without really learning how they work. Where can I find the technical details??????

[@user-dh1bo3qc2h]

Give this series a go. It's pretty technical and dives into the math: kzbin.info/www/bejne/gICmhoeqesqLr80

7:35. Why use such a complicated approach (like multiple communications and challenges) to prove that she indeed knows the secret. She could have entered into one side and come out of the other side. That proves the same thing, right? So why make it more complicated than it needs to be?

[@JarrodWatts]

Yea this example can be a little confusing sometimes. Essentially it’s setup in a weird way to showcase multiple rounds of interaction. If you changed the setup then you could likely do a single round, it’s just for example purposes

[@sirnawaz]

@@JarrodWatts Yes. I understand that after understanding non-interactive proofs. The example is deliberately made complicated to explain "interactive" proof. Thanks for the great video. I liked and subscribed it.

@@sirnawaz I wouldn't say it's "complicated" but definitely confusing like he said.
