Namecheap’s Spaceship brand has launched Thunderbolt, a privacy-focused communication app that replaces phone numbers and emails with domain names. Users verify ownership by adding DNS TXT records—no passwords, no stored messages. Thunderbolt offers encrypted messaging, voice, and video, all linked to domain-based identities. With multi-device pairing and DNSSEC baked in, it signals a shift toward decentralized, user-owned communication networks powered by the domain system itself.
