 ## Introduction
 
 The motivation behind this plan is to test how our stack(celestia-core/celestia-app/celestia-node) can withstand the max peak usage of the network from submitting data into our DA/Consensus Layer.
+In addition, this plan is covering cases where we will have different implementations of the stack(i.e. celestia-core/celestia-app/celestia-node are developed in Rust, etc.) and the plan should 
+be applied for them, too as we are having for current implementation(Go)
