A place for developers to talk about building on Farcaster.

/dev

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!

great piece, learned a lot.

how does the deltagraph receive and validate the blockchain data?

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

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

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
