Part 2 of Web3 User Profiles. In this video, we’ll be learning how to store data in the blockchain using a Solidity smart contract.
If you’re interested in learning how to store data in a blockchain smart contract, then this video is for you! We’ll be using Solidity to create a smart contract, and we’ll also be learning about Web3 User Profiles and save on gas fees. This video is a great way to understand how blockchain works and how to store data in a smart contract!
That’s not all, We will discuss how IPFS can save us gas fees by storing user information in the IPFS file blockchain but use a smart contract to save a reference to the IPFS path for the user wallet.
