97df224579 Add solidity verifier of the nova+cyclefold (#87)
* 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

fe9a488f63 Compute Decider's CM challenges in Groth16 circuit, link G16 & KZG proofs in Onchain Decider, refactor CommitmentScheme trait (#79)
* Compute Decider's CM challenges in Groth16 circuit, link G16 & KZG proofs in Onchain Decider, refactor CommitmentScheme trait

- Refactor commitment package
  - Refactor `Commitment` trait and the kzg, ipa, pedersen impls
  - Add methods to prove & verify given challenges (not computing them in-method)
- Add KZG challenges computation in decider_eth_circuit
- Add cmE & cmW KZG proving & verification in DeciderEth
- Link Decider's Groth16 proof & KZG proofs data
- Fix point to bytes arkworks inconsistency
- Patch ark_curves to use a cherry-picked version with bn254::constraints & grumpkin for v0.4.0 (once arkworks v0.5.0 is released this will no longer be needed)

* DeciderEthCircuit: Add check eval=p(c) for E & W

The check is temporary disabled due
https://github.com/privacy-scaling-explorations/folding-schemes/issues/80,
but the public inputs and logic are there, to be able to continue the
other parts development while issue #80 is solved.

b25037e34c Add IPA commitment scheme and the respective circuit verifier gadget (#72)
* Add IPA commitment native implementation

* Add IPA Gadget verifier

* polish Pedersen & IPA, add blind bool param to IPA

* Optimize IPA gadget constraints (and native):

- optimize <s,b> computation from linear to log time
- optimize s computation from k*2^k to k*(2^k)/2

* add small optimization: delegate u_i^-1 to prover and just check u_i*u_i^-1==1 in verifier circuit

* IPA polish and document

* Add 'BLIND' parameter to CommitmentProver trait (and to Pedersen and KZG impls). Fit IPA into CommitmentProver trait.

* rename 'BLIND' to 'H' (hiding) in commitment

* IPA: rm u_invs from Proof and compute them incircuit

* Update IPA's build_s & gadget to use Halo2 approach following @han0110 's suggestion.

This reduced further the amount of constraints needed.
- for k=4: -9k constraints (-7%)
- for k=8: -473k constr (-31%)
- for k=9: -1123k constr (-35%)
- for k=10: -2578k constr (-39%)
And now IPA verification (without amortizing) is very close to Pedersen
verification (in-circuits).

* rm dbg!(cs.num_constraints()) from multiple tests

* IPA::prove remove intermediate v_lo,v_hi vectors, add doc to build_s_gadget

* move powers_of into utils/mod.rs, update iters to cfg_iter
