 Not finished, implementing this in my free time to understand it better, so I don't have much time.
 
+Currently allows to do the complete path with [Pinocchio protocol](https://eprint.iacr.org/2013/279.pdf) :
+- compile circuuit
+	- parsers
+	- R1CS
+	- QAP
+- generate trusted setup
+- calculate witness
+- generate proofs
+- verify proofs
+	- with BN128 pairing

 Current implementation status:
 - [x] Finite Fields (1, 2, 6, 12) operations
 - [x] G1 and G2 curve operations
