Zero-knowledge proofs (ZK-proofs) are a key technology explored by many in the crypto industry. A zero-knowledge protocol is a cryptographic method that allows one party to prove to another party that something is true without revealing any information.

The technology is vital for layer-2 solutions to achieve blockchain scalability, and to the privacy and security of ZK transaction networks. The top ZK tokens, such as Polygon (MATIC) and Zcash (ZEC), have surpassed $9 billion in market cap since their inception.
