A place for developers to talk about building on Farcaster.

Is private messaging in Warpcast independent to the protocol or a farcaster feature?

Private messaging based on double/triple ratchet is hard to do without a server that routes messages. You also want to support push notifications, delivery if your phone is offline for awhile etc.

It’s hard to do and retain the privacy properties. My FIP goes into detail on how to provide it in the decentralized context:

@cassie any thoughts on how push notifications could be supported in a world where hubs implement FIP 99?

trade-off — a client requesting notifications for specific conversations would necessarily identify to a backend which conversations it is interested in. A user which cares about privacy could instead have a background notification worker on the app itself to perform these checks and surface notifications in-app

Push notifications are driven from two sources on most platforms: server-side or in-app, sometimes both. It is not unusual for decentralized protocols with many clients to have middleware servers, Farcaster is no different — while hubs hold casts, notifications about them do not originate from hubs. This has a —
