Nebra

NEBRA is pioneering the development of the first proof aggregation service on Ethereum. This innovative service utilizes Universal ZK-ZK Proof Aggregation construction to aggregate Zero-Knowledge Proofs (ZKPs) for various applications, including privacy-preserving identities, storage proofs, ZKML (Zero-Knowledge Machine Learning), and zkEVM (Zero-Knowledge Ethereum Virtual Machine) proofs.

What is Nebra

Nebra is a research & development organization working to make the zero-knowledge future a reality. We research and build technologies, infrastructure, and products to facilitate the mass adoption of zero-knowledge proofs.

Nebra proposes using zero knowledge proofs themselves to scale zero knowledge proof verification. As a result, zero knowledge proof settlement on Ethereum can be more accessible to the general public. The core idea is to use highly efficient recursive SNARKs (IVCs/PCDs) to get a near unlimited amount of recursion (almost) for free. This means we can recursively prove multiple zero-knowledge proofs off-chain, and verify only a single aggregated proof onchain. This significantly improves on the status quo, and provides nearly unbounded efficiency.

In March, Nebra launched Universal Proof Aggregation (UPA), a solution for scaling zero-knowledge proof verification. It said UPA reduced verification gas fees by 10 times or more, and Worldcoin, Brevis and Altlayer already used Nebra’s technology.
