Farcaster

am i understanding farcaster’s design properly that it focuses on consistency (or consensus) across all hubs?

versus activitypub’s every-server-for-itself approach (and nostr to some extent)

yes, global state on every hub (like an ethereum node)

didn't realize that. pretty interesting

how is timestamping handled?

Yes, that’s right. All hubs converge on the same state as long as they get all messages. Hubs will sync with each other to catch missed messages. But there is no explicit consensus mechanism or penalties right now (other than a poor peer score).

this is roughly correct

cc @sanjay for details

so hubs are like an L2 but specifically for cast data?
