## Goal
We should be able to prove that that a given value `x` falls in range `[a, b]`.
## Acceptance Criteria
- [x] Write a few tests cases
- [x] Create the circuit
- [x] Test the circuit agai…

A composition of zero-knowledge proofs is still a proof. `AuxInfoProof` uses its own API which is pretty similar to that of `Proof`. For consistency, we should refactor it to implement `Proof` exactly…

Zero-knowledge proofs allow someone to prove that they know a value/a value is valid, without disclosing the value. If we could implement a zero-knowledge proof system where transactions that are sent…
