We're scaling hubs to handle 10x traffic (~ 500k DAU) 

@adityapk @sanjay and @wazzymandias.eth are heads down and making some big changes this month. 

Here's a quick overview of how hubs work today.

An important part of hub performance is catch-up sync or diff sync, which kicks in when hubs get disconnected for a short duration. 

@sanjay developed this back in 2022 when we were first designing hubs.

Another piece is using a performant, type-safe language. 

Typescript served us well for the first two years, but we're reaching the limits of what a high level, garbage collected language can do. 

@adityapk has been leading the charge to re-write core parts of the hubs into Rust to speed up performance.

Another piece is gossip, or the message broadcast layer. 

We build on libp2p and @sagar and @wazzymandias.eth have both done a lot of great work to fine tune it for farcaster. 

 There's likely enough here for another video series to cover!
