Access Control with Solidity & OpenZeppelin | Authorization, RBAC (Role Based Access Control)

Most Solidity smart contracts need to implement access control. In this tutorial, I will show you how to implement basic access control with pure Solidity, as well as more advanced role-based patterns like RBAC, using the OpenZeppelin library:

• Authentication vs Authorization
• Basic access control in Solidity
• Ownable pattern with OpenZeppelin
• Secondary pattern with OpenZeppelin
• RBAC (Role-Based Access Control) with OpenZeppelin
