+In our new proof system, there's also a final steps known as the compressor and **snark wrapper**, representing an
 additional type of circuit.
 
 It's essential to note that each circuit type requires its unique set of keys.
 
 Also, the base circuits, leaves, node and scheduler are STARK based with FRI commitments, while the snark wrapper is
 SNARK based with KZG commitment. This results in slightly different contents of the keys, but their role stays the same.
+More info about commitment schemes can be found [here](https://en.wikipedia.org/wiki/Commitment_scheme).

 If you’re wondering what these setup keys contain, think of them as the 'source code of the circuit.'
