What hardware does nostr need built?
secp256k1 added to the secure enclave of all phones.

Open source phone that can run graphene or calyx. Not nostr specific, but this will be a freedom necessity sooner rather than later.
At that point might as well just run Linux.

Compatibility with hardware wallets to sign some specific kind of notes; maybe news? Or to get your #nostr account check-verified and signed.
We made a fun way to share your npub in-person with the Nostrcard at @lasereyecards https://primal.net/e/note17trfjlujr7n2hqh9n3qtdr84ru6hrrfevj459c9sw2mng3e9ksmq6j83s3
Nostr needs to work on the tens of millions of devices already built but destined for landfill. The world's poorer off will thank Nostr forever for liberating them. Sorry, you got caught up in my little hobby horse topic for the day!
