Description

How is “gas” used in Ethereum, Ethereum Classic, and other smart contract platforms? What does “Turing complete” mean? As a smart contract developer, how do I estimate how much the execution of my program will cost in gas? These questions are from MOOC 9.7 session, which took place on March 30th 2018. Andreas is a teaching fellow with the University of Nicosia.
