In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information apart from the fact that the statement is indeed true.

You can build untraceable anonymous cryptocurrencies using these algorithms.

Ah, thanks.

But I wanted to know about what Polygons ZK plans are and why GP hopes they succeed.

It is their plan to become a true L2 and not a centralized sidechain.

If they are centralized, then a ban from India wipes out polygon is my thought.
