Scaling Farcaster

• Currently 80K daily users
• How do we scale to 1M users
• Goals
  • Hubs should be less than $1000 a month
  • Message delivery, arrive in 10 seconds 90% of the time
  • 99% of hubs are “in sync”, according to some health metric.
  • 99.9% of data can replicate to an external database in < 1s.
• Sync
  • Improve Snapshot sync
  • Improve Gossip sync
  • Diff sync
• State
  • Trying to move to SSD for broader commodity hardware, while also updating hub requirements

​

Shuttle

• New replicator package
• Less opinionated compared to the older replicator
• Will give hub operators more flexibility with how they want to index and use the data

​

Frames

• Cast Actions
  • Working on discoverability, like a discover page
  • Next up would be looking into actions opening frames. e.g. you click “tip $DEGEN” and a frame pops up with how much you want to send
  • Replace or delete actions is down the road
  • Looking at moving away from deep link urls and moving towards a metadata structure similar to frames

Warpcast Topics

​

App Performance and Quality

• Direct Casts
  • Top Warpcast priority
  • Rewriting direct casts to work better at scale
  • Should have the same performance as other apps you use
  • Long term plans
    • once stable, will be looking into programatic read and writes for DCs
    • even longer term find ways to give access to DCs to other clients
• Fixing crashes and general performance

​

Notifications

• New area Warpcast team is looking to focus on
• Give people control to different categories to fine grain, but make the default algorithmic similar to the home feed
