We're starting to think about a new sync model for Farcaster. 

The current system works but is unlikely to scale up another 10x. Here's our articulation of the problem we want to go after.

A possible solution, and don't murder me for this, is maybe using some blockchain tech? If what if we attached a proof of work algorithm to limit casts from devices, hashcash style?

Network operators could tune to target a global cast rate and raise difficulty if the network grows too large.

They'd have to keep the status quo for social media experiences to make FC viable. Can't be having a chat with someone and get delays, at least not if they want FC getting any sort of mainstream adoption.
