I wrote a bit about Farcasters consensus model, and the specific tradeoffs we had to navigate. Planning on sharing more broadly tomorrow, any feedback is appreciated! https://www.varunsrinivasan.com/2024/04/28/the-goldilocks-consensus-problem

This part is easy, it just talks to a blockchain node

my mental model is prob completely wrong, but I was trying to understand why I can't just pass a fake rpc url that returns the blockchain data I want what's the cryptographic verification that I'm getting real OP mainnet data? why will other hubs reject those messages

You can fake whatever you want in a hub that you control. But other hubs that listen to OP mainnet won’t accept your messages because the signature won’t match what they expect
