Nexus Specification & VM.ZERO File Format Documentation

Introduction to Nexus

Nexus is a pragmatic, multi-language orchestration language designed to seamlessly connect code across JavaScript, Python, Rust, Go, PHP, Java, C, and WebAssembly through a clean FFI (Foreign Function Interface).

The language emphasizes orchestration-first design, allowing developers to leverage the strengths of multiple languages within a single, type-safe program.

Introduction to VM.ZERO

VM.ZERO is a secure, minimal virtual machine runtime that executes Nexus bytecode. It provides sandboxed execution with built-in security features including encryption, signing, and verification.

VM.ZERO supports multiple bytecode formats, from raw debugging formats to encrypted, production-ready images.
