FIP: Snapchain A new proposal to introduce global ordering to Farcaster hubs. We'll discuss this in more detail in the dev call tomorrow, but sharing an early draft for feedback. https://warpcast.notion.site/Snapchain-Public-0e6b7e51faf74be1846803cb74493886

Couple of questions, please: 1/ if Alice casts, will she and everyone else have to wait ~7.5 seconds on average for the next snap for her cast to be visible, including in her own local client (not sure if a client shows the local “mempool” in addition to the hub’s contents)? Could this introduce some conversational lag that wasn’t there before? 2/ if Alice posts and deletes her cast immediately, does the snap pruning mechanism mean that nothing gets written to the hubs (I’m unclear about the example provided in the doc)?

I don't think there will be a lot of delay seen for two reasons: 1. While the median time for message propagation will go up from 5s to 15s, the p95 time will probably come down. 2. Apps don't regenerate feeds in realtime because its too expensive. I have to pull stats but I'd be surprised if we regenerate feeds more often than every 30s or so.

If she posts and deletes it in quick succession, it will likely make it into the hubs for a week, and will then get pruned out completely.
