Farcaster is a fine demonstration in why you don't need strict global consensus and public blockchains for most things, but at the same time, they can prove valuable for 1 or 2 things

I hope to see more hybrid applications that are significantly better by minimizing blockchain usage only to strict global consensus

maybe we won't need those L3s after all then eh 😉

Farcaster Hubs are a form of L3.
A p2p network that stores data signed by EdDSA key tied to accounts secured by a smart contract on an L2.

Nothing says that L3s have to be implemented on a blockchain.

What do you mean by application? What does the application consist of?

what's the difference between an L3 and an application built on top of an L2?

IPFS is an open system to manage data without a central server

I'm no expert but IIRC one of the main types of L3s suggested by @vitalik.eth are Validiums which keep data off-chain.

I do consider Farcaster Hubs a form of L3, in my mental model which might not match other's.

Is that a good mental model? Anything considered a layer, tends to mean the data can be submitted to a lower layer blockchain.

By this standard, hubs are just a fully offchain data solution which interoperates with blockchain. Like the relationship between @ipfs nodes and the Filecoin network.
