The Nostr protocol was first written in 2020 by a Brazilian open source developer known by the pseudonym “fiatjaf” as a response to perceived moderation issues on Twitter, as well as both technical and cultural disagreements with other protocols such as ActivityPub and Secure Scuttlebutt.

Looks like it was never about function or protocol in the first place.

In 2024, in an article reporting on the project’s funding, Business Insider claimed to have identified fiatjaf, and had found two websites previously published by this person to disseminate the work of Olavo de Carvalho, a far-right conspiracy theorist.

Sounds lovely and taking one look at a random relay confirms this. The only things discussed there are Bitcoin, “Women-are-evil-because-they-dont-sex-me” and some AI bullshit.

This still fundamentally suffers from the oracle problem like all blockchains solutions. You can always attack these blockchain solutions at the point where they need to interact with the real world. In this case the camera is the “oracle” and nothing prevents someone from attacking the proposed camera and leveraging it to certify some modified footage. The blockchain doesn’t add anything a public database and digitally signed footage wouldn’t also achieve.
