NEBRA Labs

Nebra is a pioneering startup focused on advancing the use of zero-knowledge proofs (ZKP) on blockchains, with a particular emphasis on Ethereum. Zero-knowledge proofs are a cryptographic method that allows one party to prove to another that a statement is true without revealing any additional information. Nebra's mission is to make these proofs scalable and composable, meaning they can be easily combined and used together in various applications.

The company operates in the blockchain and cryptography market, targeting clients who are interested in privacy, security, and efficiency in digital transactions. This includes businesses and developers working on privacy-preserving identities, storage proofs, ZKML (zero-knowledge machine learning), and zkEVM (zero-knowledge Ethereum Virtual Machine) proofs.

Nebra's business model revolves around its proof aggregation service on Ethereum. This service uses their proprietary Universal ZK Proof Aggregation construction to combine multiple zero-knowledge proofs into a single, more efficient proof. By doing so, they help reduce the computational load and increase the scalability of blockchain applications. Nebra generates revenue by offering this aggregation service to clients who need to handle large volumes of zero-knowledge proofs efficiently.

In summary, Nebra is a research and community-driven project that aims to enhance blockchain technology through scalable and composable zero-knowledge proofs. They serve a niche market of blockchain developers and businesses focused on privacy and security, making money through their innovative proof aggregation service.
