Verifier circuit (#23) * ECC scalar multiplication (first draft) * fix clippy nits * start implementing the ro gadget: 1st design Poseidon + truncate * truncate to 128 bits * implement add + double in constraints * finish implementing constraints for ecc * cargo fmt * input of smul should be an array of bits * cleanup ro a bit. Make the challenge returned be a vec of allocated bits * switch to neptune 6.0 * start implementing high level circuit * incomplete version of the verifier circuit with many TODOS * optimize ecc ops. add i ==0 case to the circuit * fix 0/1 constants at the circuit * wrap CompressedGroupElement of Pallas and Vesta * cargo fmt * generate poseidon constants once instead of every time we call get_challenge * Implement RO-based poseidon to use outside of circuit. Reorganize the repo * add inner circuit to verification circuit * start adding folding of the io. there is an error in the first call to mult_mod * add test to check that bellperson-nonnative is compatible with nova * remove swap file * add another test that fails * add inputs to the circuits in tests * rename q to m in circuit.rs. add more tests in test_bellperson_non_native. change a in test_mult_mod to expose error * push test for equal_with_carried. fix the issue is src/r1cs.rs * cargo fmt + update the verifier circuit: add folding of X and update all hashes with X * make limb_width and n_limbs parameters * make params part of h1 * allocate the field order as constant. add check that z0 == zi when i == 0 * fix error in test_poseidon_ro * remove merge error * small fixes * small fixes to comments * clippy lints * small edits; rename tests * move inputize before from_num * _limbs --> _bn * _limbs --> _bn Co-authored-by: Ioanna <iontzialla@gmail.com>

Add Grumpkin cycle implementation (#181) * bn256+grumpkin from halo2curves * chore: Integrate halo2curves more extensively - Extend existing tests with additional test cases using the new curve types * fix: Assign correct orders to bn256 and grumpkin scalar fields - Swap scalar orders between grumpkin and bn256 in `impl_traits!` implementation * test: Finish improving test integration with halo2curves - Enhances test coverage for `pasta_curves` and `halo2curves` - Cleans up commented code in `test_ivc_nontrivial` and `test_ivc_nontrivial_with_compression` tests - Updates relevant test cases in `src/lib.rs` to include new curve tests * chore: Remove commented-out/uneeded code in bn254_grumpkin.rs * test: reproduce test_from_label for bn254_grumpkin - Implement the `from_label_serial` function in bn254_grumpkin provider - Add a test to compare parallel and serial implementations of `from_label` function * refactor: Clean up to_coordinate & summarize changes * refactor: rename bn254_grumpkin -> bn256_grumpkin * test: Expand testing for public params digest using bn256 and grumpkin * chore: Update halo2curves dependency in Cargo.toml - Updated the `halo2curves` dependency in `Cargo.toml` to the latest version `0.1.0` from a specific git branch. * refactor: Refactor multi-exponentiation methods across providers - Updated bn256_grumpkin.rs to use the cpu_best_multiexp function from pasta provider instead of its native function. - Modified visibility of cpu_best_multiexp function in pasta.rs from private to crate level. * chore: set up dependencies to import the correct getrandom feature on Wasm --------- Co-authored-by: Leo Alt <leo@ethereum.org>
