NIP-3B: OpenTimestamps over Signed Events

Bitcoin-anchored time-attestation protocol for Nostr events. Binds an OpenTimestamps proof to the event signature, defining the leaf digest, two on-wire transports (ots/oldots sidecar field + kind:1041 beacon), verification rules, and NIP-44-encrypted private beacons.

The Gossip Vulnerability: Why NIP-17's "Deniable" Messages Aren't

NIP-17 promises deniable messaging with its three-layer design: an unsigned "rumor," a signed "seal," and an ephemeral "gift wrap." However, this setup has a hidden vulnerability. The signed seal allows recipients to prove that a message was sent by the claimed author, even without revealing the content. This creates a perfect scenario for gossip attacks, where the mere proof of communication can damage reputations. As we explore NIP-17, we find that the rumor, despite being unsigned, is not as deniable as it seems, making it a potential risk for exposure.

Owned by No One: Solving Nostr's Key Rotation Problem

Nostr's greatest strength - that you own your identity through cryptographic keys - becomes its greatest weakness when keys are lost or stolen. This post introduces two simple, social solutions that let users mark compromised keys and rotate to new ones through community verification, without complex cryptography or pre-planning.
