* implement merkletree insert & insert-proof-verification * add merkletree circuit to verify insertion proof wip * fix merkletree's GraphViz generation for cases with empty siblings * implement tree insert-verif circuit siblings checks Note: I've implemented also an alternative version which instead of inputting a witness value 'divergence_level' it inputs a bitmask. Both approaches (divergence_level and divergence_bitmask) take the same amount of constraints (336 constraints for a tree of 32 levels, and for an hybrid approach it takes 331 constraints but the code gets a bit less readable). So I've kept with the current implementation (using divergence_level) which is more easy to follow. * [tree] modify the strategy for the insert-proof (out-circuit) * re-implement insert-proof verification circuit * add pending checks and polish * add tests for disabled(&enabled) cases that should fail * update typos.toml config * Add test with tampering * add check 5.3, to prevent tampering (at insertion proof circuit) * move old_leaf_hash computation outside the loop, simplify check 5.3 booleans * apply @ed255 review suggestions --------- Co-authored-by: Ahmad <root@ahmadafuni.com> |
