+# 1. MPC Calculation
+
+## Preprocessing phase
+Groth16: 1.5s
+
+Marlin: 10s
+
+
+## Online phase
+
+run_online.zsh(Marlin): 7s
+
+Since proving and verifying time of ciruits are depends on the number of constrains, and the way it depends is roughly the same as in the previous study, Collaboative zk-SNARKs, only the number of constrains will be recorded here.
+
+For example, when the constraints $\approx 2^{10}$ and executing in Marlin, then the Proving time $\approx 2$s as follows.
