"We have this window of opportunity to steer the LLMs and the future of technology into a freedom-tech direction." Martti Malmi & Gigi take a walk in Madeira. Recorded during SEC-07. Listen on sovereignengineering.io In this dialogue: Martti's GitHub annoyance spawned Hashtree: a content-addressed file system on top of Blossom that adds directories, file chunking, and encryption. Everything encrypted by default using content hash key encryption (inspired by Freenet), so Blossom server operators have cryptographic deniability about what they host. git remote hashtree: set up a hashtree remote for any Git repo, push to your Blossom server. Martti uses it for all Iris development, with GitHub only as a backup mirror. The web interface at git.iris.to supports NIP-34 issues and pull requests. The WebRTC mesh layer complements Blossom: peers find each other via Nostr relays for the initial handshake, then communicate directly. Requests route through peers with hops-to-live (starts around 15, probabilistically varied for privacy). No domain names, TLS certs, or IP addresses needed. Iris Browser loads apps from Hashtree URLs, bypassing web hosting entirely. Same idea as the old Freenet concept: content addressing means links don't break when servers go down. Nostr VPN was born from Martti's refusal to use Tailscale's Google/GitHub login. Built in two days. WireGuard underneath, Nostr relays for peer discovery and IP negotiation. Every device gets an npub. Exit node functionality coming, with a future Cashu-incentivized exit node marketplace. Double Ratchet messaging on Nostr: works well for two-party sessions, complexity grows with multi-device per user and group chats. Tested at SEC-07 via chat.iris.to with QR code invites. Martti prefers Double Ratchet over MLS for Nostr because MLS has stricter consensus requirements that conflict with decentralized relay sets. <
