I am curious how this really work. Let say i have web app that use react as front end and laravel as my backend. If I convert to web3 do i still need to use laravel as my backend or this will be replace with solidiity?
Solidity is a language for smart contracts that are deployed onto blockchains, it doesn’t replace your frameworks like Laravel. React, Laravel, etc. are used to build your app which can be integrated to interact with these contracts or do other things on-chain like sending payments.
