Port ProtoGalaxy initial version from
https://github.com/arnaucube/protogalaxy-poc adapting it to the current
folding-schemes lib, which is a first iteration that implements the
Lagrange-basis version from
[ProtoGalaxy](https://eprint.iacr.org/2023/1106) folding scheme. There
are some pending optimizations, but is a first step towards integrating
ProtoGalaxy in the library.
* impl AugmentedFCircuit non-base case
* add multiple iterations to AugmentedFCircuit test
* implement base case on AugmentedFCircuit and test
* Update cmE of E=0-vec to work as zero point
Update cmE of E=0-vec to work as zero point instead of as cm(0-vec)
* patch r1cs-std dep to a cherry-picked version with the zero-scalar-mult fix
* refactor FCircuit to make it more suitable inside the AugmentedFCircuit
* r1cs_parser
* z vector calculation
* test function done
* improved
* Brushuped
* add comment
* Added description of test_circuit
* found mistake
* fixed cargo.toml
* Imported ark-circom as crate
* improved l in R1CS as the number of public I/O
* separate test functions into success/failure and unify variable to pub_io_len
* removed bn254 & abstracted to PrimeField, but still some work
* add comments and clean up code
* move ark-bn254 in dev-dependencies
* abstracted test function
* fixed github action's error
* cargo fmt
* remove convert_constraints_bigint_to_scalar function
* fixed n_cols
* fixed n_cols
* Add functionality to compile Circom files in tests
* Remove test_circuit.r1cs
* Introduce CircomFrontend trait and simplify with CircomWrapper struct
* deleted the CircomFrontend
* improved
* fixed clippy lint checks of github actions
* probably fixed github actions error by changing the github yaml
* fixed github yaml, fmt, and clippy

* Port HyperNova's multifolding from https://github.com/privacy-scaling-explorations/multifolding-poc adapting and refactoring some of its methods and structs.
Note: adapted mle.rs methods from dense to sparse repr.

* HyperNova: move CCS struct outside of LCCCS & CCCS
HyperNova nimfs: move CCS structure outside of LCCCS & CCCS, to avoid
carrying around the whole CCS and duplicating data when is not needed.
Also add feature flags for the folding schemes.

- Add naive decider circuit `RelaxedR1CSGadget`, which in-circuit checks
that the given z satisfies the given RelaxedR1CS instance
- Add method to relax the R1CS instance
- Add check_relation (for testing only) to R1CS & RelaxedR1CS
- Migrate from own SparseMatrix to use ark_relations::r1cs::Matrix
- Add frontend helper to use arkworks circuits
* Implement Nova's NIFS.Verify circuits (with CycleFold)
- Add circuit for NIFS.Verify on the main curve to check the folded `u`
& `x`
- Add circuit for NIFS.Verify on the CycleFold's auxiliary curve to
check the folded `cm(E)` & `cm(W)`
- Add transcript.get_challenge_nbits
- Add tests for utils::vec.rs
* replace bls12-377 & bw6-761 by pallas & vesta curves (only affects tests)
We will use pallas & vesta curves (for tests only, the non-tests code
uses generics) for the logic that does not require pairings, and while
Grumpkin is not available
(https://github.com/privacy-scaling-explorations/folding-schemes/issues/12).
* update links to papers to markdown style
Port Espresso/hyperplonk's `virtualpolynomial`, `multilinearpolynomial`
and `sum_check` utils from
https://github.com/EspressoSystems/hyperplonk/tree/main
Each file contains the reference to the original file.
Porting it into a subdirectory `src/utils/espresso`, to have it
self-contained. In future iterations we might replace part of it but we
can keep focusing on the folding schemes part for now.
* feat: draft traits `FoldingScheme` and `Decider`
Co-authored-by: arnaucube <root@arnaucube.com>
* Add Transcript trait, with PoseidonTranscript impl (#1)
Add also the PoseidonTranscriptVar (gadget).
* Update FoldingScheme trait to take C1 & C2 as params (#2)
* Update FoldingScheme trait to take C1 & C2 as params
Update FoldingScheme trait to take C1 & C2 as params which are used by
the diverse folding schemes as a cycle of curves.
* Add constraint to FoldingScheme C1,C2 fields swap.
