Our goal is to scale Farcaster to 1 million daily users. Farcaster will need to handle 10,000 messages / second while staying credibly decentralized. That's roughly in the same order of magnitude as most global credit card networks. Here's our proposal: https://github.com/farcasterxyz/protocol/discussions/163

The most pressing problem to solve is network sync. Hubs can achieve consensus without coordination thanks to CRDTs. But they still need to replicate and converge to the same state quickly. We use a combination of snapshots, gossip and differential sync to achieve this.

The second most important problem is replication. Hubs are good for fetching state but less good at running queries on it. To do this, you'll need to transfer data into a db like Postgres, and do it in under a second. We're working on a new system called shuttle to solve this.

How do we comment on the bundles proposal? The Notion page is not open to comments as far as I can tell. (Been trying for days...)

Using something like prolly trees might help though it might be too much re-arch https://youtu.be/X8nAdx1G-Cs?si=oZ3jR-jQwqLaTt5V And a blog post explaining this sync process https://joelgustafson.com/posts/2023-05-04/merklizing-the-key-value-store-for-fun-and-profit
