Llevo semanas teniendo la misma conversación con gente que empieza en Nostr desde iOS.
Me dicen que usan un cliente que les inspira confianza. Que se siente soberano. Luego pregunto: ¿dónde vive tu nsec? Silencio. O: dentro de la app, supongo.
Esa respuesta es por qué escribí esto.
El sandboxing de iOS es real. Aísla apps entre sí. No hace nada para proteger tu nsec de la app que lo custodia. Amber no existe en iOS por una razón que no tiene solución técnica. Tu copia de seguridad en iCloud probablemente es el eslabón más débil de todo tu setup.
NIP-46 no es un workaround. En iOS es la única arquitectura que realmente aísla tu clave.

Every few weeks I end up in the same conversation with someone new to Nostr on iOS.
They tell me they use a client they trust. That it feels sovereign. Then I ask: where does your nsec live? Silence. Or: inside the app, I guess.
That answer is why I wrote this.
iOS sandboxing is real. It keeps apps from reading each other. It does nothing to protect your nsec from the app holding it. Amber does not exist on iOS for a reason that will not be fixed. Your iCloud backup is probably the weakest link in your whole setup.
NIP-46 is not a workaround. On iOS it is the only architecture that actually isolates your key.

Zap splits are the first revenue sharing mechanism that doesn't require a platform. YouTube takes 45% and decides what you can say. On Nostr: you keep whatever percentage you choose, with no one deciding anything. That's not a feature. That's the architecture.

And that's why every CBDC rollout starts with soft incentives: convenience, subsidies, cashback. They know the math won't sell itself. They're betting most people won't do the math in time.
