The Year Encrypted Messaging Came to Nostr

In an era of increasing surveillance and data commodification, the need for sovereign encrypted messaging has never been more Nostr offered a promising foundation: a decentralized protocol that lets users own their identity and broadcast messages across a network of relays without requiring permission. But it had a gap. While public notes could flow freely, private communication remained an unsolved problem. NIP-04, Nostr's original encrypted messaging spec, had critical cryptographic vulnerabilities. NIP-17 improved on this but still leaks metadata and offers no forward secrecy or post-compromise security.
