Nostr double ratchet pull requests for Bitchat. Forward secrecy enables disappearing messages feature: past messages on relays can't be decrypted anymore after key rotation. Also future messages stay safe even if one key is compromised. I don't know how mergeable it is in its current form, but I've tested it to work between real Mac and Android devices.

Iris Audio

Spotify clone on nostr / blossom / hashtree. Data is loaded from peers over webrtc even if you disable the blossom servers. Hashtree is a nostr native "IPFS lite", basically just blossom + directories and file chunking. Everything is content hash key encrypted by default, which is nice for blossom server admins. More:

hashtree - share privately

Content-addressed file sharing and decentralized git hosting. No accounts, no servers, no DNS.

Btree indexes on hashtree enable large, searchable decentralized databases that can be used for all kinds of "platform" applications. Hashtree indexes can be queried a bit like nostr relays, but they're not tied to any IP address, domain name or host. You can sync them over any transport and search offline. Content-addressed indexes are transparent: you can verify that you see the same search results as others and aren't shadowbanned. You can easily fork the large indexes (such as audio.iris.to catalogs) and add your own results into them, even in the browser.

I may have created the killer app of Nostr: MIDI Enshittifer Also demonstrating Iris Sites, a way to easily deploy websites over nostr / blossom / hashtree.

Could bitchat use wifi aware on android? The bandwidth would allow to send images and files and sync chat histories quickly. @calle

"Thank you for contacting us. We’ve received your support request and will get back to you as soon as possible." Waiting for permission to publish my iOS app 💔

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.

Got annoyed by Tailscale requiring 3rd party accounts, so created 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.

Qwen 3.5 probably not good for coding vs Codex and Claude, but could be interesting for local feed curation
