## changelog - rename the `encode` function to `prove` and have it take _shards_ instead of an _encoding matrix_: this is to isolate the "encoding" process inside the `fec` module and leave the main `komodo::prove` only compute the "proof", i.e. the commits of the data from ```rust fn encode<F, G, P>( bytes: &[u8], encoding_mat: &Matrix<F>, powers: &Powers<F, G>, ) -> Result<Vec<Block<F, G>>, KomodoError> ``` to ```rust fn prove<F, G, P>( bytes: &[u8], powers: &Powers<F, G>, k: usize, ) -> Result<Vec<Commitment<F, G>>, KomodoError> ``` - rename `fec::Shard.combine` to `fec::Shard.recode_with` to get rid of "combine" - rename `fec::recode` to `fec::recode_with_coeffs` to show that this version takes a list of coefficients - rename `Block.commit` to `Block.proof`: "commit" should be "commits" and it's usually refered to as "proof" - split `prove` further into `prove` and `build`: `prove` now outputs a `Vec<Commitment<F>>`, `build` simply takes a `Vec<Shard<F>>` and a `Vec<Commitment<F>>` and outputs a `Vec<Block<F>>` - add `fec::recode_random` that does the "shard" part of `recode` to wrap around `fec::recode_with_coeffs` - remove `R: RngCore` from the signature of `zk::setup`, to avoid having to pass a generic `_` annotation everywhere `zk::setup` is used, same change has been applied to `recode` and the `generate_random_powers` in `main.rs` from ```rust fn setup<R: RngCore, F: PrimeField, G: CurveGroup<ScalarField = F>>( max_degree: usize, rng: &mut R, ) -> Result<Powers<F, G>, KomodoError> { ``` to ```rust fn setup<F: PrimeField, G: CurveGroup<ScalarField = F>>( max_degree: usize, rng: &mut impl RngCore, ) -> Result<Powers<F, G>, KomodoError> { ``` ### some extra minor changes - remove some useles generic type annotations, e.g. `prove::<F, G, P>` can become a simpler `prove` most of the time, i.e. when there is at least one generic annotation somewhere in the scope

there was some missing parts from recent commits and also a dead link to `setup::setup` which is now `zk::setup`.

in 3c91ef12 and !54, a new implementation of the creation of the _trusted setup_ has been introduced, that gets rid of the `E: Pairing` requirement with a more general `<F: PrimeField, G: CurveGroup<_>>`. however, the size of the _trusted setup_ was incorrect. `zk::setup` requires the _maximum degree_ of the _trusted setup_, however, the number of bytes `nb_bytes` was consistently being given to it throughout the code base... this MR - introduces a new `zk::nb_elements_in_setup` that converts a number of bytes to the associated number of _trusted setup_ elements - uses that new `zk` function before calling `zK::setup` in all the code base ## results >

woopsie, it was missing from !54

## changelog - remove `ark-poly-commit` from the dependencies - remove the old `setup.rs` - add temporary `foo.rs` which define (some details are ommited for brevity) - `struct Powers<F, G>` - `struct Commitment<F, G>` - `fn build_powers<F, G>(...) -> Powers<F, G>` - `fn commit<F, G, P>(powers: &Powers<F, G>, polynomial: &P) -> Commitment<F, G>` - tests - `foo.rs` is then renamed to `setup.rs` - two new `KomodoError` variants have been created to replace `ark_poly_commit::Error` - `DegreeIsZero` - `TooFewPowersInTrustedSetup(usize, usize)` - finally, all the past mentions to `E: Pairing` and `setup::random` have been replaced with `F, G` and `setup::build_powers` respectively
