In CycleFold we want to compute
$P_{folded} = P_0 + r ⋅ P_1 + r^2 ⋅ P_2 + r^3 ⋅ P_3 + ... + r^{n-2} ⋅ P_{n-2} + r^{n-1} ⋅ P_{n-1}$,
since the scalars follow the pattern r^i Youssef El Housni (@yelhousni)
proposed to update the approach of the CycleFold circuit to reduce the
number of constraints needed, by computing
$P_{folded} = (((P_{n-1} ⋅ r + P_{n-2}) ⋅ r + P_{n-3})... ) ⋅ r + P_0$.
By itself, this update reduces the number of constraints as the number
of points being folded in the CycleFold circuit grows. But it also has
impact at the HyperNova circuit, where it removes the need of using the
bit representations of the powers of the random value, substancially
reducing the amount of constraints used by the HyperNova
AugmentedFCircuit.
The number of constraints difference in the CycleFold circuit and in
the HyperNova's AugmentedFCircuit:

* 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.

const generic
* feat: create a `dummy` method for nova witnesses as well
* chore: clippy - removed unused imports
- Adds the logic to support multi-instances folding in HyperNova's
AugmentedFCircuit & IVC.
- Adds also methods to generate new LCCCS & CCCS instances that don't
depend on the main folding chain, to be folded in in the next step
- Updates CycleFold circuit & methods to work other folding schemes than
Nova, adapting it to fold multiple points per circuit (instead of
2-to-1 as till now)
- Handle multi-instances folding in the FoldingScheme trait
interface, which expects 'None' in Nova, and 'Some' in HyperNova &
other multi-folding schemes.
* Remove the trait bound `C::BaseField: PrimeField` for better DX
* Methods in `TranscriptVar` now exactly matches the ones in `Transcript`
* Add `ProtoGalaxyTranscriptVar` and `CommittedInstanceVar` for protogalaxy

- in some tests, increase the size of test matrices to a more real-world size.
| method | matrix size | old version seconds | new version seconds |
| --------------------- | ------------- | ------------------- | ------------------- |
| compute_g | 2^8 x 2^8 | 16.48 | 0.16 |
| compute_g | 2^9 x 2^9 | 122.62 | 0.51 |
| compute_Ls | 2^8 x 2^8 | 9.73 | 0.11 |
| compute_Ls | 2^9 x 2^9 | 67.16 | 0.38 |
| to_lcccs | 2^8 x 2^8 | 4.56 | 0.21 |
| to_lcccs | 2^9 x 2^9 | 67.65 | 0.84 |
- Note: 2^16 x 2^16 is the actual size (upperbound) of the circuit,
which is not represented in the table since it was needing too much
ram to even be computed.
* Optimize HyperNova's `compute_sigmas_thetas` and `compute_Q`
| method | matrix size | old version seconds | new version seconds |
| ------------- | ------------- | ------------------- | ------------------- |
| compute_sigmas_thetas | 2^8 x 2^8 | 12.86 | 0.13 |

* 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.

- The License badge is not needed since there are already many links to
the license both in the readme and in the GitHub UI
- The CI checks badge, already appears in the GitHub UI in the last
commit preview at the main repo page. Furthermore, after some months
of inactivity, the badge would be 'gray' as 'inactive'.
- The only badge that I was trying to get there is the 'docs' badge, to
make it very clear that the docs page exists, but it was a bit to hard
visually to have a single badge there, and furthermore the docs link
already appears in the readme twice, and also in the GitHub UI
right-panel.

* Format
* Reduce the number of constraints in `AugmentedFCircuit`
For the test `folding::nova::tests::test_ivc`
Before: 138240
After: 86756 (1.6x improvement)
Two notable optimization techniques:
1. Instead of allocating two witness variables `a, b` and enforce their equality by calling `a.conditional_enforce_equal(&b, &cond)`, we can avoid the allocation of `b` and directly set `b = a`. The former might be costly due to the checks in allocation and `conditional_enforce_equal`. See `nova/circuits.rs` for details.
2. Before this commit, `NonNativeFieldVar::to_constraint_field` was majorly called for generating the inputs (preimage) to hash functions. However, it turns out that the underlying conversion strategy (optimized for weight) is not optimal for reducing the length of hash preimage. We can go further by maximizing the number of bits per limb, thereby minimizing the preimage length. See `circuits/nonnative.rs` for details.
* Format
* Fix clippy warnings
* Move the comments to the right position
* Cleanup unnecessary code
* Treat (the digest of) `cf_U_i1` as an additional public input to `AugmentedFCircuit` for full soundness
* Fix the y-coordinate in the affine form of zero points
This in turn fixes the inconsistency between the digest of a constant affine point and that of a witness affine point in circuits.
* Set `cf_u_i1_x` to the correct value
* Fix the number of public inputs in dummy instance and witness
* Unify the logic behind `CycleFoldCommittedInstanceVar::hash` and `CycleFoldChallengeGadget::get_challenge_gadget`
* Add `ToConstraintFieldGadget` bound to `GC2`
* Remove unnecessary code used for debugging
* Make clippy and rustfmt happy
* Move conversion methods for `NonNativeFieldVar` to `folding/circuits/nonnative.rs`
* Simplify the check of zero coordinates
* Gracefully handle the result of `nonnative_field_var_to_constraint_field`
* Make clippy happy again
* 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.
* Change CycleFold approach:
Instead of having a single CycleFold circuit that checks the 2 forign
scalarmul of the main circuit instances, now there are 2 separated
CycleFold circuits each of them checking a single foreign scalarmul.
Increasing the number of constraints of the AugmentedFCircuit, but
reducing the number of constraints in the CycleFold circuit, which will
translate into reducing the number of constraints in the Decider
circuit.
* CycleFold circuits checks in AugmentedFCircuit:
- update NonNativeAffineVar to work with NonNativeFieldVar directly
instead of FpVar comming from NonNativeFieldVar.to_constraint_field()
- include in AugmentedFCircuit intermediate steps inbetween CycleFold
circuits, and update the internal checks of the CycleFold circuits
Pending to document the new CycleFold circuits approach and better
variable namings, rm unwraps, etc
* matrix_vec_mul_sparse gadget: skip value * v[col_i] mul when value==1
Saves a notable amount of constraints since there is a notable amount of
1 values in R1CS matrices.
* Reuse computed vector of U_i
Reuse computed vector of U_i, saving 4k constraints in AugmentedFCircuit.
* fixes post last rebase to main
* rm test_augmentedfcircuit since it is already tested in test_ivc (and is a slow computation)
* rm dbg!()
* small fixes after last main rebase
* 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
* Fix Nova multi-elements state
In the AugmentedFCircuit the default value for the state when no input
is provided was `vec![F::zero()]`, which defaults to length `1`. So when
having more than 1 element in the state, before even starting to fold,
the circuit was already already failing.
Additionally this commit adds an example for a circuit with a state of 5
elements.
