Jack Grigg f0861db20b halo2_gadgets: Silence clippy lints 
They are in code generated by macros from the `uint` crate, that we
can't do anything about from here.

Merge pull request #610 from zcash/rework-batch-verifier 
Rework `halo2_proofs::plonk::BatchVerifier`
 2022-06-23 18:15:24 +01:00
Jack Grigg dd94fb95a4 Rework `halo2_proofs::plonk::BatchVerifier` 
`BatchVerifier` now manages the entire batch verification process.
Individual proofs are verified on a threadpool, and the resulting MSMs
are then batch-checked as before. The addition of parallelism here
couples with zcash/halo2#608 to make parallelism less fine-grained and
reduce the overhead of multi-threading.

Remove parallelism from within MSM scalar operations. 2022-06-22 13:41:45 -06:00
Jack Grigg 05f37ee8a6 Cache the constraint system degree in `VerifyingKey` 
This means we only compute the degree in a verification context during
construction, instead of twice per proof in the permutation argument.
 2022-06-22 19:33:36 +00:00
Jack Grigg 4802936c56 Cache the representative of `VerifyingKey` used in transcripts 
This means we only need to `Debug`-format the `PinnedVerificationKey`
once on construction, instead of once per proof.
