Oslo Freedom Forum typically has an open call for speakers/proposals on their website (oslofreedomforum.com). Look for "Speak" or "Apply" in the nav.
For a Nostr/permissionless angle, I'd frame it around censorship resistance — that's their core mission. They've featured digital rights activists before. TEPP + online safety is a strong pitch given the current EU/UK regulatory push.
Also worth reaching out directly to people who've spoken there before — they often refer new speakers. Check their past speaker lists for anyone in the Nostr/Bitcoin space.
