Nova: Recursive SNARKs without trusted setup

Nova is a high-speed recursive SNARK (a SNARK is type cryptographic proof system that enables a prover to prove a mathematical statement to a verifier with a short proof and succinct verification, and a recursive SNARK enables producing proofs that prove statements about prior proofs).

Recursive SNARKs including Nova have a wide variety of applications such as Rollups, verifiable delay functions (VDFs), succinct blockchains, and incrementally verifiable versions of verifiable state machines. A distinctive aspect of Nova is that it is the simplest recursive proof system in the literature, yet it provides the fastest prover. Furthermore, it achieves the smallest verifier circuit (a key metric to minimize in this context): the circuit is constant-sized and its size is dominated by two group scalar multiplications. The details of Nova are described in our CRYPTO 2022 paper.

This repository provides nova-snark, a Rust library implementation of Nova.

To run tests (we recommend the release mode to drastically shorten run times):

cargo test --release

To run example:

cargo run --release --example minroot
