A Rust implementation of the Cairo virtual machine for executing and proving provable programs in the StarkNet ecosystem.
Cairo VM is a Rust implementation of the Cairo virtual machine that executes programs written in the Cairo language. It enables provable computation where one party can verify execution correctness without re-running the program, primarily serving as the execution engine for StarkNet's zero-knowledge proof ecosystem.
Blockchain developers working with StarkNet, cryptography engineers implementing zero-knowledge proof systems, and developers building applications requiring verifiable computation.
Developers choose Cairo VM for its superior performance over the Python implementation, strong safety guarantees from Rust, and production-ready status as the primary VM for Cairo programs in the StarkNet ecosystem.
cairo-vm is a Rust implementation of the Cairo VM. Cairo (CPU Algebraic Intermediate Representation) is a programming language for writing provable programs, where one party can prove to another that a certain computation was executed correctly without the need for this party to re-execute the same program.

Rust implementation delivers faster execution and enhanced memory safety over the Python VM, with benchmarks showing significant speed improvements for programs like large Fibonacci computations.
Serves as the primary execution engine for StarkNet, having replaced the older Python version in production, ensuring reliability for blockchain applications.
Executes programs written in both Cairo 0 and Cairo 1, maintaining compatibility with the evolving Cairo ecosystem for provable computation.
Includes a tracer for visualizing memory and register changes during execution, aiding in debugging and program analysis without external tools.
Only implements a limited number of Python hints, requiring extensions via Rust code or cairo-vm-py for custom hints, which restricts flexibility compared to the original Python VM.
Requires multiple dependencies like Rust, uv, and make, with an installation script and environment setup, making initial setup cumbersome for newcomers.
Admits missing some features from the original Python VM, such as unrestricted Python hint execution, which can hinder migration or advanced use cases.
