Lab: Solidity Basics - The Blockchain Messenger¶
In the previous section you setup remix and already compiled and interacted with a smart contract. But you don't have much solidity knowledge yet.
In this section we're build a Smart Contract called "The Blockchain Messenger". 💪🏻
The goal is very simple: This one will save a message on the Blockchain, readable to everyone, write able only to the person who deployed to contract.
We also count how many times the message was updated.
At the end of the section you should have a better understanding of the most important value types in solidity, a special kind of variable type called address, the important global msg-object and a few of its properties. You will also know the basic structures like read/write functions and constructors.
