The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Visibility - Public Private Interna

The video tutorial explores the concepts of data access in smart contracts, focusing on public, private, and external function access. It demonstrates how changing a function's access level affects its visibility and interaction within a contract. The tutorial highlights the implications of these changes, such as the inability to call private functions from other functions and the restriction of external functions to be called only outside the contract. The video aims to enhance understanding of function scope and accessibility in smart contract development.
