bellman is a crate for building zk-SNARK circuits. It provides circuit traits
and primitive structures, as well as basic gadget implementations such as
booleans and number abstractions.
bellman uses the
group crates to build circuits generically over a
scalar field type, which is used as the "word" of a circuit. Arithmetic
operations modulo the scalar field's prime are efficient, while other operations
(such as boolean logic) are implemented using these words.
bellman bundles an implementation of the Groth16 proving system.
This will be moved into a separate crate in the future, and
contain any utilities that make implementing proving systems easier.
