Efficient pairing library using polynomial representation of field elements, written in Cairo 🐺.
Garaga can enable efficient pairing operations in StarkNet, by using polynomial representation of field elements. This is a work in progress, and is not yet ready for production use.
Here are some interesting use cases enabled by Garaga:
- SNARKs on StarkNet: would enable privacy-preserving computations on StarkNet.
- KZG cryptographic commitment scheme.
- Identity-based encryption schemes.
- Attribute-based encryption schemes.
- BLS (Boneh–Lynn–Shacham) Digital Signature scheme.
We are exploring many optimizations techniques. For example, we are currently working on a new technique to reduce the number of constraints in the pairing computation. This technique is based on the idea of using a polynomial representation of field elements.
Specifically for profiling, the following tools dependencies are required:

- Huge props to tekkac and feltroidprime for their initial work on provable pairing-based cryptography in StarkNet.
- Credits to Nethermind for their initial work on optimized modular arithmetic.
Here are some interesting resources about pairing-based cryptography:
Note: This list is not exhaustive, and is not intended to be.
- Document A :: Pairing for beginners : A beginner-friendly overall introduction of the concept and techniques, including Towered extension fields in section 7.3. (2012)
- Document B :: Efficient Hardware Implementation of IFp-Arithmetic for Pairing-Friendly Curves : Fast Fp modular multiplication using polynomial representation of field elements. Currently being implemented. (2012)
- Document C :: High-Speed Software Implementation of the Optimal Ate Pairing over Barreto–Naehrig Curves Useful, relatively effective ready-to-use formulas including for Fp, Fp12 arithmetics. Should be composable with Document B.
- Document D :: Efficient Multiplication over Extension Fields Generalized Arithmetic on any extension field using polynomial representation of field elements. This work could enable polynomial representation of elements of finite field of any prime order, and thus very efficient pairing for any BN curve, including alt_bn128.
- Document E :: Accelerated tower arithmetic Close to state-of-the art solution for Fp12 arithmetics. Similar to Document D but harder. (2019)
