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

* 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

/*
Sonobe's Nova + CycleFold decider verifier. Joint effort by 0xPARC & PSE.
More details at https://github.com/privacy-scaling-explorations/sonobe
Usage and design documentation at https://privacy-scaling-explorations.github.io/sonobe-docs/
Uses the https://github.com/iden3/snarkjs/blob/master/templates/verifier_groth16.sol.ejs
Groth16 verifier implementation and a KZG10 Solidity template adapted from https://github.com/weijiekoh/libkzg.
Additionally we implement the NovaDecider contract, which combines the Groth16 and KZG10 verifiers to verify the zkSNARK proofs coming from Nova+CycleFold folding. */
