The prover transforms a computation into a constraint system (e.g., R1CS), generates a small proof, and the verifier checks it against a verification key. SNARKs are non-interactive (one message) and succinct (small proofs). Most require a
zk-SNARKs power ZK rollups (zkSync, Starknet variants), private transactions (Zcash), and verifiable compute. Their succinctness makes on-chain verification practical, enabling trustless scaling and privacy at scale.
رسم المعرفة
14 relations1. What Is a zk-SNARK
A zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is a cryptographic proof system that lets a prover demonstrate knowledge or correctness succinctly, with verification that takes milliseconds regardless of computation size.
2. How It Works
The prover transforms a computation into a constraint system (e.g., R1CS), generates a small proof, and the verifier checks it against a verification key. SNARKs are non-interactive (one message) and succinct (small proofs). Most require a trusted setup ceremony; newer designs (e.g., PLONK, recursive SNARKs) reduce or remove setup assumptions.
3. Why It Matters
zk-SNARKs power ZK rollups (zkSync, Starknet variants), private transactions (Zcash), and verifiable compute. Their succinctness makes on-chain verification practical, enabling trustless scaling and privacy at scale.
4. Key Facts
- Succinct: proof size is small regardless of computation
- Trusted setup is required by classic SNARKs
- PLONK and Groth16 are widely used schemes
- Recursive SNARKs prove proofs, enabling aggregation
