* Add solidity verifier of the nova+cyclefold, and add method to prepare the calldata from Decider's proof. Missing conversion of the point coordinates into limbs (ark compatible)
* chore: adding comments linking to the contract's signature
* chore: update .gitignore
* chore: add num-bigint as dev dependency
* fix: work with abs path for storing generated sol code
* chore: update comment
* feat: solidity verifier working on single and multi-input circuits
* feat: multi-input folding verification working + fixing encoding of additive identity in calldata
* chore: make bigint a dependency
* refactor: import utils functions from utils.rs and make them available from anywhere
* chore: make utils and evm available publicly
* fix: pub mod instead
* chore: make relevant method public and add `get_decider_template_for_cyclefold_decider` to exported objects
* solidity-verifiers: move tests to their corresponding files
* small update: Cyclefold -> CycleFold at the missing places
* abstract nova-cyclefold solidity verifiers tests to avoid code duplication, and abstract also the computed setup params (FS & Decider) to compute them only once for all related tests to save test time
* small polish after rebase to last main branch changes
* rm unneeded Option for KZGData::g1_crs_batch_points
* add checks modifying z_0 & z_i to nova_cyclefold_solidity_verifier test
* add light-test feature to decider_eth_circuit to use it in solidity-verifier tests without the big circuit
* solidity-verifiers: groth16 template: port the fix from https://github.com/iden3/snarkjs/pull/480 & https://github.com/iden3/snarkjs/issues/479
* add print warning msg for light-test in DeciderEthCircuit
* solidity-verifiers: update limbs logic to nonnative last version, parametrize limbs params
solidity-verifiers:
* update solidity limbs logic to last nonnative impl version, and to
last u_i.x impl
* parametrize limbs params
* add light-test feature: replace the '#[cfg(not(test))]' by the
'light-test' feature that by default is not enabled, so when running
the github actions we enable the feature 'light-tests', and then we can
have a full-test that runs the test without the 'light-tests' flag, but
we don't run this big test every time. The choice of a feature is to
allow us to control this from other-crates tests (for example for the
solidity-verifier separated crate tests, to avoid running the full heavy
circuit in the solidity tests)
* move solidity constants into template constants for auto compute of params
* polishing
* revm use only needed feature
This is to avoid c depencency for c-kzg which is behind the c-kzg flag
and not needed.
* nova_cyclefold_decider.sol header
* rearrange test helpers position, add error for min number of steps
* in solidity-verifiers: 'data'->'vk/verifier key'
* add From for NovaCycleFoldVerifierKey from original vks to simplify dev flow, also conditionally template the batchCheck related structs and methods from the KZG10 solidity template

* 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.
---------
Co-authored-by: George Kadianakis <desnacked@riseup.net>
- 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
