Nexus is a pioneering zero-knowledge virtual machine (zkVM) designed to enable verifiable computing at scale. Developed to support Rust programs, the Nexus zkVM uses advanced cryptographic techniques to generate highly efficient, incrementally verifiable computations (IVC). This open-source, modular, and extensible system optimizes prover performance and supports custom computations. Nexus aims to transform digital interactions by prioritizing correctness, transparency, and security, making large-scale verifiable computing accessible and efficient.
