 Zero-knowlege proofs use [arithmetic circuits](https://medium.com/web3studio/simple-explanations-of-arithmetic-circuits-and-zero-knowledge-proofs-806e59a79785), which don't have an easy equivalent to an `if` statement.

 **Note:** Compilation of Zokrates programs and key creation are slow processes. There is no need to repeat them every time, just when map size changes. On a production system you'd do them once, and then store the output. The only reason I am not doing it here is for the sake of simplicity.
