As we know the original Nova implementation is based on R1CS. Our target is to implement a plonkish versioned NOVA, folding multiple Customer Gate/Lookup instances into one respectively. Thereafter, we can feed the folded instances into the relaxed Plonk SNARK.
- Jellyfish(TurboPlonk/UltraPlonk) supporting relaxed plonkish circuit SAT
- KZG pcs for primary proof over BN254 curve, and IPA pcs for secondary proof over Grumpkin curve
- Poseidon Circuit based Jellyfish
- Keccak Transcript
- Native verification for final first proof (Bn254 curve)
- Non-native verification for final secondary proof (Grumpkin curve)
Before intensive coding we will give more comprehensive details as much as possible, including some attestation code:
- Thinking in Folding Scheme: Cross Term in R1CS
- Thinking in Folding Scheme: Cross Term in Plonk
- Thinking in Folding Scheme: Cycle Curves
- Plonk From Scratch
