VEry nicely explained and its very important to understand these scaling solutions as they should be coming up to enhance Ethereum Blockchain.

it's inconvenient to wait for a week to withdraw funds in optimistic, lets see how it goes, some DEFI applications should have deployed that by now, end of July but I have heard no news of it.

these roll ups have to be deployed soon coz we have been waiting for a long while for the scaling solutions.
