The Iterator Function: A Complete Guide to Understanding This Blockchain Concept

The iterator function mentioned earlier performs various vital functions that are used to set the next state of the machine and eventually the world state.

These functions include the following: It fetches the next instruction from a byte array where the machine code is stored in the execution environment.
