Farcaster Devs

Is there a way for a client to tag a cast with a flag that prevents other clients from indexing the cast?

Eg. say I'm building Hypercast, and I only want Hypercast to show certain casts. Right now, if a user makes a cast, and it gets sent to hubs, all clients will show this cast by default. Is there an alternative?

ah got it. that’s not possible as far as I’m aware

The ask is I want the other clients to exclude casts, not include by default 

App namespacing / sharding is a good way of framing it

Is your app generating the casts it wants to display? When you generate a signer for a user, the app’s FID is part of that payload, so you could use that to filter for casts that were created from your app

should do, it’s part of the cast body but it’ll look weird on other clients that doesn’t understand the non standard

Will the hub still store it?

And I guess client validation will reject the message due to the prefix, unless the client is aware?

just force prefix a byte of data on the cast and prune it on your client view until it becomes part of the protocol. 

suggested this idea a long time ago but the geniuses didn’t seem sold on it

It wouldn’t work if other hubs couldn’t see the casts anyway

Just a hack to make indexing easier for you

It doesn’t make the cast not show up on other clients

Can you point me to docs? Trying to understand if this would be a hack or not (ie. having an invisible channel for a client)

You could use the parent url or parenthash to tag it

That’s how channels work

Or some part of the cast text as encoding 

Could you have a Hypercast network? https://www.thehubble.xyz/intro/networks.html
