WiFi Direct and peer-to-peer video calls protocol
A first engineering sprint: a 200 KB transport threshold that opts large payloads out of BLE mesh into WiFi Direct on Android and MultipeerConnectivity on iOS, with WebRTC signaling tunneled through the existing Noise session. Scaffold, not ship-ready.

Pay-to-message bonds: spam control without moderators security
How a small Lightning bond attached to an unsolicited DM changes the economics of spam. No captcha, no identity check, no review queue. Just an extra step that costs the sender actual money, in sats.

The case for ephemeral networks vision
The internet is not a law of physics. It is cables and towers and a handful of companies. What happens when the wire is cut. Why the answer is not another cloud, but a smaller, closer, shorter-lived network.
Syndication
Every post is also broadcast as a NIP-23 long-form Nostr event (kind 30023) tagged with the Hoppr publication pubkey. Atom feed and RSS mirror arrive alongside the v2.1 app release.
