* Optimize the HyperNova `compute_g`, `compute_Ls` and `to_lcccs` methods
- Optimize the HyperNova `compute_g`, `compute_Ls` and `to_lcccs` methods
- 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 |
| compute_sigmas_thetas | 2^9 x 2^9 | 100.01 | 0.51 |
| compute_Q | 2^8 x 2^8 | 4.49 | 0.07 |
| compute_Q | 2^9 x 2^9 | 70.77 | 0.55 |
* optimize LCCCS::check_relation & CCCS::check_relation, and remove unnessary methods after last reimplementations
* migrate from CurveGroup to PrimeField in hypernova & ccs when curve whas not needed to simplify the code
* refactor test of compute_c circuit to use multiple lcccs&cccs instances
* refactor hypernova's compute_c circuit to reduce from `110635` to `553` constraints
* apply review nits
* fix clippy lints after rust-toolchain v1.76.0
* 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.
* 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).
