This repository is a curated list of resources for learning and programming in Noir, a domain-specific language for zero-knowledge applications. It targets developers, researchers, and enthusiasts interested in building privacy-preserving applications, smart contracts, and other ZK-based systems. The benefit is a centralized, comprehensive collection of libraries, tools, examples, and educational materials to accelerate development and understanding of the Noir ecosystem.

How It Works

The list categorizes resources into logical sections, covering everything from official documentation and starter templates to specific libraries for cryptography, data manipulation, and machine learning. It also highlights development tools, IDE integrations, proving backends, and real-world projects built with Noir. This structured approach allows users to quickly find relevant information and understand the breadth of the Noir ecosystem.

Quick Start & Requirements

• Installation: Primarily involves using the nargo binary, which is the Noir package manager and compiler. Specific installation instructions for nargo and related tools are available in the official documentation.
• Prerequisites: Generally requires a recent version of Rust and Node.js for certain tools and front-end integrations. Some advanced examples or proving backends might have specific hardware or software dependencies (e.g., GPU for certain computations, specific CUDA versions).
• Resources:
  • Official Docs: https://noir-lang.org/
  • GitHub: https://github.com/noir-lang/noir
  • Discord: https://discord.gg/noir-lang

Highlighted Details

• Extensive coverage of cryptographic primitives including various hash functions (Keccak256, Poseidon), encryption schemes (AES, ChaCha20), and signature algorithms (ECDSA, EdDSA, Schnorr).
• Numerous libraries for numerical operations, data type manipulation, and complex data structures like Merkle trees and linked lists.
• A wide array of development tools, including IDE extensions (VS Code, Neovim, Emacs), package managers, and cross-platform compilation targets (JavaScript, mobile).
• Showcases diverse applications, from DeFi and gaming to identity management and social media, demonstrating Noir's versatility.

Maintenance & Community

The repository is actively maintained by the Noir community, with contributions from various organizations and individuals in the ZK space. Links to official community channels like Discord and forums are provided for support and discussion.

Licensing & Compatibility

The repository itself is typically licensed under an MIT license, but the individual projects and libraries linked within may have different licenses. Users must verify the licensing of each specific resource for compatibility with commercial or closed-source projects.

Limitations & Caveats

Some linked resources, particularly benchmarks and specific proving backends, may require updates to reflect the latest Noir versions and performance characteristics. The repository also includes a disclaimer advising users to exercise caution with third-party content.
