What is a Groth16 proof?

Groth16 is a zero-knowledge proof (zk-SNARK) protocol that enables efficient verification of computational results without revealing the underlying data. This cryptographic method generates a succinct proof that can be quickly verified, offering privacy and scalability benefits for blockchain applications. Groth16 is particularly useful in systems where privacy is essential, such as privacy-focused cryptocurrencies (e.g., Zcash) or decentralized identity solutions.
