* feat: Basic Ova NIFS impl working
The implementation follows the spec outlined by Bunz in:
https://hackmd.io/V4838nnlRKal9ZiTHiGYzw?view.
With this, the NIFS works and passes all tests.
* chore: Resolve all TODOs and warnings
* add: Docs for the NIMFS of the scheme and related structs
* chore: update imports
* add: Docs for all Ova NIFS functions
* fix: Unify nomenclature for all variables and elements within NIFS tests
* fix: Uniformize instance order in fn calls
* chore: pass clippy
* chore: clear all clippy findings in tests
* chore: Remove `mimc` from spelling checks
* chore: Address PR reviews
* fix: Use `target_pointer_size` conditional compilation
There are some parts of the code where is needed to de/serialze
`usize`s. These, have sizes that vary depending on the target
achitecture the code is compiled for.
Hence, this adapts the de/serialization to the specific pointer size for
which the crate is being compiled to.
* change: Support WASM-compatibility and polish Cargo.toml
In order to support Wasm-compat and to simplify and improve `Cargo.toml`
readability, the follwing changes have been made:
- All the deps that can use `parallel` feature, do so. As `rayon`
supports non-threaded targets with a fallback option. See: https://docs.rs/rayon-core/1.12.1/rayon_core/index.html#global-fallback-when-threading-is-unsupported
- `ark-grumpking` has been brought to `0.5.0-alpha.0` as `0.4.0` appears
to not be in `crates.io` anymore. See: https://crates.io/crates/ark-grumpkin/versions
- By default, the crate uses `"ark-circom/default"` which selects the
`wasmer/sys` feature such that it knows where wasmer is
suposed to be run`.
- Added a `wasm` feature which forces `ark-circom/wasm` to be used
instead. Which internally selects the `wasmer/js` backend to be used
such that in-browser execution is possible.
- Added `getrandom` with `js` feature as dependency when `wasm32-unknown-unknown` target is selected such
that compilation of the crate for testing or simply building is possible. Notice that with `wasi` and other wasm targets,
this is not the case as they're automatically supported.
For more info, please check: https://docs.rs/getrandom/latest/getrandom/#webassembly-support
* feat: Support WASM-compatibility tests in CI
Add support for both testing the build of `sonobe/folding-schemes` for
WASM-targets and also, it's build as a dependency for a WASM-crate.
This includes a build job for the three main supported rust-WASM targets
and the same but for a thrid crate creted on-the-fly which uses
`sonobe/folding-schemes` as a dependency.
* chore: Add README docs about WASM-compat & feats
* ci: don't run WASM-compat job if PR is draft
* chore: depend on `arnaucube/circom-compat` fork.
Since https://github.com/arnaucube/circom-compat/pull/2 was merged, we
can already switch to it as we were depending before.
* chore: minimal build/test instructions
* fix: CI typos
* fix: Update CI to use correct feature sets
* fix: `ark-grumpkin` versioning issues
As mentioned in
https://github.com/privacy-scaling-explorations/sonobe/issues/146
there's a big issue that involves some dependencies of the crate.
As a temporary fix, this forces the workspace to rely on a
"non-existing" version of `ark-grumpkin` which is immediately patched at
workspace-level for a custom version that @arnaucube owns with some
cherry-picked commits.
While this allows the CI to pass and crate to build, a better solution
is needed.
* fix: Clippy CI avoiding --all-targets
* fix: use `wasm` feat only with folding-schemes
* feat: `Nova` can be serialized and deserialized
* chore: (temp) allow dead code as serde is not yet used
* fix: require trait in `where` to not increase restrictions on
`CommitmentScheme`
* feat: add file with nova serialization methods
* fix: change call to get poseidon config and chore: update traits for serde
* chore: remove clang install from CI, move tests and remove unnecessary
allow
* feat: remove serializing r1cs and cs params and provide them at
deserialization time
* chore: initialize r1cs within deserialization function directly
* circom: add external_inputs
* adapt new external_inputs interface to the FoldingScheme trait and Nova impl
* adapt examples to new FCircuit external_inputs interface
* add state_len & external_inputs_len params to CircomFCircuit
* add examples/circom_full_flow.rs
* merge the params initializer functions, clippy
* circom: move r1cs reading to FCircuit::new instead of each step
* CI/examples: add circom so it can run the circom_full_flow example
* 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
