WebMar 16, 2024 · However, in the last few years, researchers have figured out how to combine the sum-check protocol with cryptographic commitments to obtain arguments that are both zero-knowledge and succinct for NP statements. This has led to zk-SNARKs with state of the art performance (e.g., Hyrax, zk-vSQL, Libra, Virgo, Spartan ).

The commitment is a useful tool in cryptography that is often utilized with the zero-knowledge proof. In principle, the commitment is designed to ensure some values are selected in the correct manner. The description is subtle so let’s consider a concrete case: a ‘Rock Paper Scissor’ game. Let Alice and…
