What exactly is the Primal caching service? Is it a relay with extra bells and whistles?

Do you have thoughts?

Not sure how they're doing it, but here's how I'll be doing it:

Replying to @USER

I'm not a fan of Primal's lightning wallet kyc, and wooden recommend it to people comma but in terms of how their handling performance as a Nostr client, I might be doing the same thing if I'm understanding them right.

On my end, everything so far is pretty much on Nostr, however, there will be a normal backend/database server running alongside it, not caching the nozzle event data itself but saving event addresses, for the purpose of quickly identifying and loading in people's posts and increase reliability overall. This would be running in parallel with what's currently there.

This side supporting a traditional server is not needed for the client to work, it only enhances it, and it'd lower in cost than if it was holding all the data.

I think this approach is the best way to go about it, where it would

Replying to @USER

That's why it's not reliant on it. If it gets attacked then that's that, the site is still running, just not in pristine condition. That's about it.

And yeah that can work too, in the app/setting page there'd be:

Title: Caching Server [button: add]:

Subtitle: Official servers:
cahcing.degmods.com [button: unset]

Subtitle: Recommended servers:
caching.example1.com [button: set]
caching.example2.com [button: set]
caching.example3.com [button: set]

Subtitle: Custom/user servers:
input-field [button: add]
caching.exampleCustom.com [button: set]

This can be a nip too, now that I think about it.

Didn't do much research, so sprinkle salt on this.

@miljan can you clarify or point me to some docs?

Why not use a caching relay, is it because of counts and such?

Does the caching service strip signatures? Does the client verify signatures?

I think it's a server (or collection of servers) that's running redis or something like it. It caches everything posted to whatever relays it's monitoring, and delivers it to the user on request. But posting new notes or replies goes through a user's defined relays.

Are signatures still validated client side, or can the cache tamper messages?

That I cannot say. I'm deducing its methodology based on what we can see as users. I suspect it may not be preserving signatures, but I just don't know.

They read the relays. Then store everything, but they can choose what to censor or not. They only show you portions of what you or others note.

Any relay can choose what to show you and what not to show you.

That probably depends if their clients validate the signatures properly. Check the source code.

Since each note is signed by your nsec. I’m fairly sure they can’t modify. They can and have censored people’s notes. Selected not to show a given note or not allow some things in search.

That’s fair. But they are knowingly censoring content.

I have also read on here that primal app doesn't function when you disconnect from their server. Even when connected to other relays

Tbh it is a bit unfortunate but I understand; its a great way to bootstrap the network for a new user to feel like a more traditional social media. They'll find their way to other nostr clients as they see fit, with the power of their npub

I should clarify. They can “choose” to only show you portions of what you or others note.
