Nucleus – A security-hardened, Nix-native container runtime

Nucleus is a security-hardened container runtime built natively on Nix, designed for developers and security engineers who need reproducible, tamper-proof environments. It leverages Nix’s declarative package management and cryptographic hashing to eliminate supply chain attacks and enforce strict isolation without sacrificing performance. This project is interesting because it reimagines container security from the ground up, offering a deterministic alternative to Docker that integrates seamlessly with Nix-based workflows.
