therealyingtong 48b862f13f Circuit::synthesize(): Nullifier integrity. 2021-07-21 20:35:43 +08:00
therealyingtong 3a75f875a4 poseidon::pow5t3.rs: Take partial_sbox advice column as input. 
This was previously creating an extra advice column. Instead, we
should pass in all required advice columns as inputs.

Jack Grigg 15f9d254d9 Migrate to latest `halo2` API 
- `halo2::plonk::{create_proof, verify_proof}` now take instance columns
  as slices of values.
- `halo2::plonk::Permutation` has been replaced by a global permutation,
  to which columns can be added with `ConstraintSystem::enable_equality`.
- The introduction of blinding rows means that various tests now require
  larger circuit parameters.
