## Problem
These two structs serve roughly the same purpose. The Aztec version was made just for type safety reasons, so it doesn't apply the necessary constraints.
## Solution
Replace usage of Aztec's version of U128 with Noir's. This will likely reduce performance by some delta given that Noirs version uses two u64s and Aztec's version uses a Field.
We can make the transition smoother by adding from_field to Noir's version of U128
