Hi @chesatochi.

It's really cool, isn't it? ZKP has opened so many new possibilities to the space.

There are quite a few protocols that use ZKP actually. ZCash is built on the zk-snarks mechanism of ZKP; Ethereum had soft forked it's protocol to include zk-snarks for Smart contracts. The list goes on.

The article following this will answer all your question on the application and use cases of ZKP. Be sure to check that out.

Thanks.
