How Nostr Chats Really Work

Ever wondered how private chats work on a public, decentralized network?

Continuum v1.6.7.7 — Toward a Fully Encrypted Sovereign Workspace

Today's work pushed Continuum further toward becoming a true sovereign local-first workspace. The focus was not on “cloud sync” or engagement mechanics. It was on reducing plaintext exposure, improving encrypted workspace handling, and making the local environment more durable and portable across different deployment models. Another important milestone: PDF exports are now supported consistently across all build types, including environments where WeasyPrint is unavailable.
