    1. 0.2. How ZK-SNARKs Work
    2. 0.4. Why ZK-SNARKs Matter

ZK-SNARK stands for Zero-Knowledge Succinct Non-Interactive Argument of Knowledge, a cryptographic proof that allows one party to prove possession of certain information without revealing it or engaging in back-and-forth communication.

How ZK-SNARKs Work

ZK-SNARKs enable trustless verification of data. They allow a prover to demonstrate that a statement is true (e.g., a transaction is valid) without revealing the actual data or requiring interaction with the verifier. These proofs are small, fast to verify, and require no further communication once generated. They’re widely used in privacy-focused blockchains like Zcash to ensure transaction confidentiality.

Why ZK-SNARKs Matter

ZK-SNARKs are essential for privacy, scalability, and security in blockchain systems. They power anonymous transactions, enable confidential smart contracts, and support efficient Layer 2 solutions like ZK Rollups. As demand grows for privacy-preserving and scalable blockchain applications, ZK-SNARKs are becoming a foundational tool in modern crypto infrastructure.
