A lot does actually come from Fediverse, but the bridge doesn't show everything. Even in my end the threads break apart. What most people here reply to usually aren't directed towards Nostr users and is just a bridge.

Nostr has always been a thought, but it's worth understanding some team members know little to nothing about it because they come from a different subject matter. At the moment some who are affiliated who are familiar have separate keys to represent independently to put the work off. At first, I don't even think it was understood that these posts were bridged from another platform - but now everyone is aware.

GrapheneOS can't just "get" Nostr immediately. There is infrastructure that would need to be built to use it in a highly secure manner. Just HODLing a singular private key for a shared project account is unacceptable. It would also be limited to just posting. Rotating npubs is also something to avoid entirely. A hardware signer could fit but you also need a client supporting it and it's costly. It needs to be discussed more.

Same also goes for accepting Lightning payments in general. The project would want a secure Lightning node with lnurl and BOLT12. We also need to make sure we have proper accounting for all the money the node is receiving, inbound capacity and backups.

Last I remember the project couldn't figure out a good way to set up lnurl without using sketchy or excessive software. We want to set it up ourselves on top of the usual server setup we use rather than using a premade OS or container setup, and with channel backups. We'd need to set high fees for routing and figure out getting inbound capacity regularly.

At the moment there's a lot of work on the table with other stuff though.
