I have worked on it together with the Nestr "decentralized GitHub" team. Nestr frontend and Iris are built from the same codebase using build configuration options for different branding and features. You can easily extend the configuration to make your own branded version. Source code to be released soon™.
The client is based on NDK. Full SocialGraph up to 2nd degree is downloaded on first login, and thereon only missing follow lists are queried. I'll be experimenting with options to go beyond 2nd degree.
The graph is serialized and saved locally in a compressed format, which is much faster to load than it is to reconstruct the graph from Nostr events. My graph consisting of 260 follow lists and 23000 users is 3 MB on disk.
It's still very much work-in-progress and mostly tested on desktop Brave, but it's already my favorite way to browse Nostr.

Iris / Snort show a purple checkmark badge for users you follow, orange for users who are followed by at least 10 users you follow, and gray for users followed by at least 1 user you follow. One more improvement would be saving the followed user's name at the time of follow, and showing it (with an asterisk like Discord petnames) even if the user changes their name. That would further help prevent impersonation.

Blossom is great. Should we integrate it into nostr relays as a websocket command so you don't need separate media hosts? Or use DVM so you can also pay for downloads?
Same "get blob by hash" command could be used by more advanced structures like merkle trees for large files that can be chunked and downloaded from multiple peers simultaneously like torrents.
Video file in a merkle tree could be used for streaming: you'd publish the latest merkle root every few seconds?

IrisDB uses tag-replaceable events of kind 30078.
"d" tag is the "file path", for example "groups/follows/somePublicKey" or "user/profile/name". You can update the content of the "file" with a new event that has the same tag.
"f" tag is the "directory path". "groups/follows" in this case. You can list all the "files" in the directory by querying relays with the "#f" tag filter. Strfry doesn't index this field, but some relays do.
Content field is the file content, can be any JSON serialized data.
If we did profile fields and follow lists this way, there would be no overwrite problem when you sign in to a new device that doesn't have your previous profile or follow list. If we did likes that way, unliking would be trivial.
When we create new Nostr apps or features, we don't need to come up with new obscure event kinds. D tag "apps/events/some-event-name/participants/some-public-key" is more descriptive than some random number that might still conflict with someone else's application.
I wanted to name it "treelike" instead of IrisDB in order to not sound overly complicated, but the npm package name was already taken.

Under the hood, IrisDB uses events like this:
{
"content": "\"Test Document\"",
"created_at": 1713958806,
"id": "4ade41ea3f724dd944b6e861882015ea355ad262879e32970482b64806bd91d8",
"kind": 30078,
"pubkey": "ec1c45f69d463143ac1882c52b27db551342a24add13810b5d98b96298e4d9e1",
"sig": "cbc373003989470414cba8660e26e0b5902ec8fea00d54ef4e38fdfc93631a0b3fd1bb53203a9f60003e760d8d4ee3ecebbd676c2529d3c753cbf3714d511421",
"tags": [
[
"d",
"/apps/docs/documents/868d7ed9-1100-4cae-be58-16a7d248afc7/name"
],
[
"f",
"/apps/docs/documents/868d7ed9-1100-4cae-be58-16a7d248afc7"
]
]
}
"d" tag is the "file name". It's a replaceable event, so new writes to the path overwrite the previous value. "f" is the "directory name" where the file resides. "#f" nostr filter can be used to list the files in a directory.

Made a pull request to the nips repo https://github.com/nostr-protocol/nips/pull/1027

2024-02-06 12:08:43

Local sqlite db by @npub1v0l…qj49 is great. So much better than IndexedDB. Iris & Snort can now store a lot of data locally, sync only what they don't already have (negentropy & nip-114) and eventually do p2p over webrtc. Works offline.
Iris now features a "for you" feed which uses the local database. It scores events by recentness, author favoriteness (top authors reacted by you) and amount of reactions from users who often react to the same notes as you.
Recentness is randomly weighted to occasionally show older events as well. Recent notes from all followed users are also mixed in.
Events are marked "seen" when they've been in the viewport for 1 second and not shown again in the "for you" feed. I've found it actually pleasant and interesting to use now. New feed every time.
It's not extensively tested yet, and might not show great results before your local database is populated with notes and reactions. Also, it's unfortunate that sqlite wasm persistence (origin-private filesystem) requires some http headers that broke youtube and some other embeds.

Trending notes from nostr.band API are localized, but that only reveals your locale to nostr.band.
The bigger privacy issue is that Nostr clients send your IP in every direction in nip05 lookups and relay connections, especially with the outbox model which connects to other users' relays when you visit their profiles.
If you don't want to reveal your IP address, VPN or Tor is the best solution.

2024-01-31 10:48:25

Pull requested to strfry. Thoughts?
---
NIP-114: ids_only filter
When a subscription has a filter with ids_only: true, the relay responds with [HAVE, subId, eventID] messages. The client can then request the full event from only one relay instead of receiving it from all subscribed relays. If the event is already in a local database, the full event request can be skipped altogether.
I have not implemented this for the stream command yet, but this could save a lot of bandwidth if you're connecting to many other relays and subscribing to everything.
We might also want a GET message that is sent in response to HAVE messages to request the full event without creating a subscription.

Simple "for you" algorithm at https://beta.iris.to/ . It first checks who have reacted to the same posts as you, and then shows posts that those people have reacted to.
It's building the feed using IndexedDB in a web worker. When you open the page, it loads some events from relays into IDB, but the more events you have there the better the results. It rebuilds the feed every minute, or you can hit refresh.
I find the feed more interesting than plain timeline, but it should also include recent posts by users whose posts you react to, and some randoms. Ordering by score instead of time would be interesting to try.
@npub1dcl…x5ey was experimenting with logistic regression algorithms already last year. That might produce better results. https://github.com/adamritter/light-nostr-client/blob/master/src/lib/logistic_regression.ts

Actually simpler and more efficient than the "not" filter could be if relays just advertised event ids that match the subscription and only sent the full event on demand.

Iris / Snort is actually using the outbox model (by @npub1v0l…qj49 ) so yes, incoming duplicates in queries by author would probably not see a 90% reduction, but maybe some other queries like reactions and replies would.
However, the bigger savings arise from having a local db and not having to download events you already have. Efficient sync protocols like negentropy let your local relay sync with as many relays or peers as you want at a low cost, which is good for decentralization.
While the outbox model helps break out of centralized relays, it's even better if the content can be found and synced from many places, including our pockets. If Alex Jones had public write relays, they'd be targets for DDoS and harassment.

2024-01-15 15:31:05

Added support for "not" filter to Iris. It adds filter { not: { ids: alreadyHave }} to all queries in order to avoid downloading events that you already have locally. It's only sent to relays that support nip 113 (which I haven't written yet).
https://github.com/irislib/iris-snort/blob/d359f3123abb4a1ff08b41e70501a8c985df9775/packages/system/src/query-manager.ts#L130
Also implemented it in nostr-rs-relay, although haven't tested with a real database yet: https://github.com/mmalmi/nostr-rs-relay/commit/55eb916123006f1ca9ca7b4bb107e69deac3579d
If you're connected to 10 relays and query them sequentially, adding alreadyHave to each request you might save up to 90% in bandwidth by not getting the same events 10 times.
However, I started thinking if it would make more sense to just implement negentropy in the browser and nostr-rs-relay. It's more efficient sync, but more difficult to implement.
I think { not: { ids: alreadyHave }} might be the main use case for the not filter. One consideration is that the "not" part might be so large that you need to discard it on the relay after eose.
Any other use cases for not filter? Maybe excluding muted authors from a global query, but not sure if worth it.

Maybe nostr protocol would be the right interface? Ofc it can be wrapped in get / set or publish / subscribe methods. https://github.com/nostr-protocol/nips/blob/master/01.md#communication-between-clients-and-relays

Anyone had issues with NDKCacheAdapterDexie? Tried using it for loading of profiles in Iris but cpu and memory usage went through the roof. NDK worked fine without it. @npub1l2v…ajft https://git.v0l.io/mmalmi/snort/src/branch/ndk

Personally I don’t want notifications other than DM either, but someone might want. We’ll make it configurable. I got a notification from this repost btw.

If you don't have Nostr push notifications yet, you can get them from Iris and Snort web versions.
You can subscribe to notifications by going to the Notifications page, or Settings / Notifications on Iris, where you can also check the subscription status.
On iOS, you need to save Iris / Snort to the home screen in order to enable notifications.
Notifications are currently sent from all mentions, replies, DMs and zaps.

Thanks for pointing me to Tailwind and Vite! They’re great, using them in Iris / Snort now.

Doesn't even need to be chat-only, but good chat UX is necessary. I think push notifications are key.

Push notifications can be sent encrypted, and then decrypted on the client side.

Yes, I did the first half of the bounty as a client specific implementation but haven't had the bandwidth to do a NIP 🙈 There still seems to be a lot of ongoing development in the space.

Also private messaging is less dependant on the network effect than public messaging: you don't need to do everything on the most popular platform.

To be more specific, I was talking about these kinds of expensive branded supplements that often have quite exotic ingredients. If you choose to do vitamins and minerals etc., you can get them in a more wallet friendly way in bulk.
