Hmm, NAT hole punching failure comes to mind if they're on separate networks. For that case, we'd need forwarding of the traffic via relay, like tailscale does it. Have you tried if they connect on the same local network? Could be something else too.

Nostr running android phones could detect each other via BLE and automatically sync events with random nearby peers over Wifi Aware? Sneaker network. When the internet is turned off, you could sync your feed in Moscow by taking the subway.
On iPhone I suppose it would require keeping the app open and maybe accepting every pairing.

The problem persists. My internet is otherwise fine, speed tests shows 80 mbps upload. The timeout is probably something that can be solved on the zsp app level even if upload is slow at 100 kbps.
That said, thanks for running zapstore! Such an improvement over play store.

Tailscale / headscale / Nostr VPN solve connections between changing IP addresses behind NATs. Nostr VPN doesnt have a TURN server though, so doesn't work in cases where NAT hole punching fails.

Got annoyed by Tailscale requiring 3rd party accounts, so created Nostr VPN. https://github.com/mmalmi/nostr-vpn
It signals over nostr relays and creates a wireguard / boringtun network. Builds for Macos and Linux. Using it between my Macs, but haven't tested extensively yet.

Usually equally sized leaf nodes, but that's not enforced. Actually I made a video-chunker which makes the first chunk 256kb so it starts faster, while the rest are 2MB. Bittorrent v2 compatible 16kb would have been nice, but it's too much overhead for blossom servers.

At this point it's nice hacking, but not very productive yet. It needs to become more proactive and autonomous, while being conscious of token limits, or hopefully running on decent local models soon. But I think we'll have actually useful and easy to set up agents later this year.

2026-01-27 07:55:43 UTC

Iris has had double ratchet messaging for a long time, but trying to support multi-device made it flaky. Now I made https://chat.iris.to/ which is single device and works pretty reliably.
Using it to control my clawdbots. Had to set it up because whatsapp / signal setups were such a pain. Also I didn't want to use nip04 which would reveal all our chat history if the private key was ever leaked.
On command line the clawdbot uses nostr double ratchet tool ndr in rust: https://files.iris.to/#/npub1xndmdgymsf4a34rzr7346vp8qcptxf75pjqweh8naa8rklgxpfqqmfjtce/nostr-double-ratchet
And of course my clawdbots use git-remote-htree for decentralized code sharing on nost + blossom — not annoying github tokens.

Unfortunately no: content is encrypted by default so there's no way to tell what's in there.
Limited storage quotas for free users (per user & total) and dropping least recently requested files is the best spam prevention policy I can think of. Maybe combined with IP based filtering, although that can be bypassed.
I'm currently running my own cdn.iris.to (writes via upload.iris.to) which only allows encrypted binary uploads to avoid moderation issues.

You don't need to trust blossom servers, content is verified by hash. There might be direct nav problem in urls right now, working on it. In the meantime you can go to files.iris.to root and paste the url into the search input once relays have connected.

Hashtree is very simple, it's just blossom + "this is how you define directories and chunk files". Merkle roots are saved in nostr events so you can have npub/path directories whose content you can edit. Files.iris.to supports nip-34 pull requests and issues. You could use it as one remote even if you also use grasp.

They're merkle trees on blossom. Kind 30078 event with ["d", "videos/videoname"], content: merkleRoot points to them. I might actually just make ["d", "videos"] which would contain all your vids in the same merkle tree dir, less event fetching.

Initial clone from a git pack would be faster than fetching each object separately. But packs change hash whenever anything is added, so you'd lose the deduplication that the hashtree filesystem provides: same object in two repos would be stored twice.

2025-12-27 10:12:30 UTC

- reply

I just installed ngit, trying it out. Git's native sync is faster than requesting every object by its blossom content hash. On the other hand, git-remote-htree doesnt require git servers, just blossom or webrtc peers.

2025-12-27 10:01:16 UTC

- reply

Sha256 would be nice, but this is just a git remote helper. Choice of hash algorithm depends on how you init your git repo: git init --object-format=sha256. It stores the .git dir structure (with sha1 blob filenames by default) on blossom.

Conceptually safe, but the implementation is vibe coded and not audited. Better to use for public or semi-public sharing for now. Files are content hash key encrypted and uploaded to hashtree.iris.to blossom server (which also stores to cloudflare r2 cdn.iris.to). Encrypted file chunks are also shared over WebRTC via online peers.

Not yet on Iris. I guess could add support for nhash and npub/path addressed media embeds, but that wouldn't work on other clients.
CI/CD would be interesting: you could list CI/CD npubs in the git repo and UI would load their status reports from the hashtree. They would track npub/repo on nostr and run on changes.

https://github.com/mmalmi/hashtree-ts - it's basically blossom with directories and file chunking.
* Merkle tree roots published on nostr, so you can have npub/path addressed directories whose content you can update.
* Chunks are encrypted by default (Freenet style CHK content hash key encryption).
* Peers request chunks over WebRTC with Freenet style privacy preserving HTL hops-to-live algorihtm.
* HTTP blossom servers used as fallback.

Code is the spec 😬 https://github.com/irislib/meet using ephemeral 25050 evts to do signaling. Sending participant profile as rumor over datachannel. Chat messages sent over peer datachannels, unsigned.

Fixed graph-api.iris.to, now it's able to serve crazy big graph snapshots again. This graph is 30MB serialized, with 300K users and 12M follow relationships. https://npub1g53mukxnjkcmr94fhryzkqutdz2ukq4ks0gvy5af25rgmwsl4ngq43drvk.blossom.band/b0821561955e10f7d5aaeb2fcdcb80f315234e6131287a9163cf33cac1cdb95a.png

Happy to have inspired 😀 Having a real DB that juggles between memory and disk and saves the indexes sure makes sense.
I could try and see if nostr-social-graph could use indexeddb and not have to load everything into memory on app start. For native, I've made a social graph pull request to nostrdb: https://github.com/mmalmi/nostrdb
