Zero-Knowledge Proofs are currently expensive and time-consuming. That's why you don't see them in your software yet. Nockchain’s ZK-PoW mechanism is all about making ZKPs cheap and fast for anyone in the world. Nockchain does this through its block reward. It pays people $NOCK to get better and better at ZK-proving. This lets app developers access verifiable computation cheaper than otherwise. This is how Nockchain makes the ZKP a cheap and abundant commodity, integrated into everything.
