Sean Bowe	06552eec44	Update the PLONK implementation to adapt to the new transcript API.	2021-01-06 10:45:11 -07:00
Jack Grigg	f49e1e6177	Fix breakage of trait resolution in Rust 1.49.0 ... Previously, `ChallengeScalar` could use the operator traits defined on the `F: Field` type it wrapped, due to its `impl Deref<Target = F>`. This was technically ambiguous, and Rust 1.49.0 makes that ambiguity an error. We could fix this by adding operator impls with `ChallengeScalar` on the RHS, but that would conflict with zcash/halo2#111. Instead we manually dereference every challenge scalar when used in an arithmetic operation.	2021-01-06 00:48:29 +00:00
