This commit contains the following modifications: - Add tests for Lookup, ECC, Merkle, and Sinsemilla to verify that the verification key and the proof have not been modified by comparing them to those saved in a file. - Introduce a `LookupRangeCheck` trait that provides common methods for a lookup range check. - Use this new trait as a generic parameter in configs, chips and tests that are using lookup. - Create a new Lookup chip which is optimized for 4, 5 and 10-bit range check and add tests for this new chip. - Add `init_from_private_point` parameter in `SinsemillaConfig`. If this parameter is set to false, the `SinsemillaChip` is the same as the current `SinsemillaChip` used in vanilla circuit. Otherwise, the `SinsemillaChip` is modified to support hash from private point. --------- Co-authored-by: YaoGalteland <yao@qed-it.com> Co-authored-by: Dmitry Demin <dmitry@qed-it.com> Co-authored-by: Constance Beguier <constance@qed-it.com>
Fix clippy warnings
- Move lookup table `load` function into `LookupRangeCheck` trait (and remove `table_range_check_tag` function which is no longer used) - Move some imports to reduce the diff with the main branch - Standardize test circuit names with `My...Circuit` convention - Reduce visibility of some functions - Update changelog file
…okup table (#43) This PR adds a comment to clarify why a duplicated-rows range check lookup table was chosen.
