Overview
A zk-SNARK is a zero-knowledge proof with succinct verification and small size. It lets a prover prove a statement without revealing details. It is widely used in privacy and scaling.
How It Works
A prover generates a SNARK for a computation, and a verifier checks it quickly with a small proof. Most SNARKs require a trusted setup. They are efficient to verify on-chain.
Why It Matters
zk-SNARKs enable private transactions and scalable rollups. Their small proofs suit blockchain verification. The trusted setup is a security consideration.
