Feature/traits (#3) * 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.

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 --------- Co-authored-by: dmpierre <pdaixmoreux@gmail.com>
