ZK-SNARKs are an extension of the zero-knowledge protocol (ZKP) which secures communications by sharing knowledge of a secret, by never revealing the content of the secret itself. In other words, it’s a form of cryptography. Here’s what ZK-SNARKs stands for: “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge”. A zero-knowledge proof or ZKP is an interactive protocol between a prover (who knows the witness) and a verifier (who has to be convinced). Z ero knowledge proofs like zk-SNARKs have a wide variety of applications: Zcash uses zero knowledge for privacy, Coda and Mir to compress an entire blockchain into only a few kilobytes, and 0x and For zkSNARKs, there is usually a setup phase and after that a single message from the prover to the verifier. Furthermore, SNARKs often have the so-called "public verifier" property meaning that anyone can verify without interacting anew, which is important for blockchains.

Can you Handle the Truth My interest in ZK Snarks began at work, when I took the task to investigate this technology and implement a prototype that could later evolve into a product. This post is the first of a series chronicling our progress in that exploration, and the difficulties we found. Exploring SNARK Recursion without pairing cycles https://github.com/zcash/zcash/issues/4092 Halo: Recursive Proof Composition without a Trusted Setup https Teraz sa pozrime na príklad. Predstavte si, že ste v miestnosti s niekým, kto má zaviazané oči. Na stole pred vami sú dve gule: biela a čierna. Druhej osobe (overovateľovi) musíte dokázať, že gule majú skutočne inú farbu, bez toho, aby ste prezradili, ktoré z nich.

Zcash is the first widespread application of zk-SNARKs, a novel form of zero-knowledge cryptography. The strong privacy guarantee of Zcash is derived from the fact that shielded transactions in Zcash can be fully encrypted on the blockchain, yet still be verified as valid under the network’s consensus rules by using zk-SNARK proofs.
