If you struggle understanding "why would we need L2/3/4s?", then here is a diagram that shows how web3 social stacks like Farcaster already rely on a multi-layer set up.

Each layer builds upon the last, but adds new app specific logic/data.

Right now, there is no proof aggregation being sent downwards. But proofs will be important as we will want to prove the minimum amount to make a concept (i.e. warps) composable across layers.

Export data from any web application and prove facts about it without compromising on privacy.

or I might be just too lost in a sauce and midcurving everything given the current state of blockchains - who knows! but this is all very fun!

Building blocks like @tlsnotary, @eas_eth, noir from @aztecnetwork, js microrollups with @0xStackr, and proof agg with @nebrazkp will become very important for bringing this all together.

I personally hope these teams can work together to build some sort of easy to use sdk!
