Note: This library is copied from https://github.com/shuklaayush/noir-bigint, and prime_field is changed to be specifically used for BLS12_381 prime field
This library provides a custom BigUint56
data type, allowing for computations on large unsigned integers. The integers are represented with a fixed number of limbs, each of which is a 56-bit unsigned integer.
We utilize u56
limbs for two primary reasons:
- 56 is divisible by 8, simplifying conversions to/from bytes.
- Multiplication requires a double-width intermediate value and
u112
is the maximum double-width value that can be represented in Noir.
This library provides various functionalities such as arithmetic operations (addition, subtraction, multiplication, division), bitwise operations (left shift, right shift), comparisons and conversions (to bytes, to bits).
In your Nargo.toml
file, add the following dependency:
[dependencies]
noir_bigint = { tag = "v0.0.1", git = "https://github.com/onurinanc/noir-bigint-bls12_381" }
Tests are run using nargo
:
nargo test
All tests are run as part of the CI pipeline test.yaml
.
