234600b39f Move the experimental frontends into a separate crate, so that when not using them they don't take several minutes to compile (and indirect dependencies). (#168)
This saves several minutes (and MBs of data) on compilation time both
when running tests in this repo, but also when using the sonobe lib as a
dependency in external repos.

edcef6c352 implement Nova's Offchain Decider (prover & verifier) for non-ethereum cases (#164)
The idea & motivation is that the [onchain
decider](https://privacy-scaling-explorations.github.io/sonobe-docs/design/nova-decider-onchain.html)
could still be used for non-onchain verification but the proving time is
big (eg. a little bit less than 3 minutes on my laptop) since the
circuit is big due the EVM constraints. Whereas with this new [offchain
decider](https://privacy-scaling-explorations.github.io/sonobe-docs/design/nova-decider-offchain.html)
we can generate the proofs much faster for the cases where it is not
required to verify the proofs in the EVM.

The code is mostly abstracted from any specifics of the current usage of
Groth16 & KZG10, with the idea that eventually in the future we can have
Spartan plugged in and use non-pairing-curves such as pallas&vesta. For
the current version it relies on KZG10 commitments.

The logic implemented in the code of this commit can be found at the updated
docs section 'offchain decider':

52de2d185c feat: Minimal in-browser compatibility for the crate (#149)
* change: CircomWrapper constructor to use raw bytes

* chore: tmp update to latest circom-compat

* feat: Introduce PathOrBin to support in-browser CircomWrapper usage

This changes the associated type `Params` of the `CircomFCircuit` to use
the newly created `PathOrBin` type.

This allows the user of the lib to directly send the binary of the files
already read or instead, provide a path to it and let `sonobe` do the
work.

With this, Circom should be already usable from the browser if we allow
JS to take care of reading the `.wasm` and `.r1cs` files.

* feat: Introduce PathOrBin to support in-browser NoirFCircuit usage

This commit temporarilly stands on top of
https://github.com/dmpierre/arkworks_backend/pull/1 referenced as `rev`.

This changes the associated type `Params` of the `CircomFCircuit` to use
the newly created `PathOrBin` type.

This allows the user of the lib to directly send the binary of the files
already read or instead, provide a path to it and let `sonobe` do the
work.

With this, Noir should be already usable from the browser if we allow
JS to take care of reading the `circuit.json` files

* chore: Update deps to branch instead of `rev`

* fix: use PathOrBin in examples

* fix: clippy

* fix: read file length for initializing vec size

5ec9c2c576 Enable WASM-compat and monitor it in the CI (#142)
* 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

* 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

* 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

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.
