Noir is a Domain Specific Language for SNARK proving systems. It has been designed to use any ACIR compatible proving system.
This implementation is in early development. It has not been reviewed or audited. It is not suitable to be used in production. Expect bugs!
Read the installation section here.
Once you have read through the documentation, you can visit Awesome Noir to run some of the examples that others have created.
Backends:
- Barretenberg via FFI
- Marlin via arkworks (Note -- latest interfaces may not be updated to support Marlin backend. Please open an issue if this is relevant to your project and requires attention.)
Compiler:
- Module System
- For expressions
- Arrays
- Bit Operations
- Binary operations (<, <=, >, >=, +, -, *, /, %) [See documentation for an extensive list]
- Unsigned integers
- If statements
- Structures and Tuples
- Generics
ACIR Supported OPCODES:
- Sha256
- Blake2s
- Schnorr signature verification
- Pedersen
- HashToField
The current focus is to gather as much feedback as possible while in the alpha phase. The main focuses of Noir are safety and developer experience. If you find a feature that does not seem to be in line with these goals, please open an issue!
Concretely the following items are on the road map:
- General code sanitization and documentation (ongoing effort)
- Prover and Verifier Key logic. (Prover and Verifier pre-process per compile)
- Fallback mechanism for backend unsupported opcodes
- Visibility modifiers
- Signed integers
- Backend integration: (Bulletproofs)
- Recursion
- Big integers
