I know there is a lot covered by the main places for programming but bitcoin specific information is pretty thin on the ground. Having a sub for help and presenting technical stuff - how to's and development tips this sort of thing.
I think it would do quite well and attract a lot of traffic from the autistic Bitcoin devs out there. Oh, and Nostr and LN of course.
Stuff like:
- Physical security - encryption and backup
- Building with API toolkits, SDKs and RPCs related to these subject areas
- Server deployment, security, etc. How to set up a really anonymous hidden service end to end, services that accept crypto, how to never leave the simple to avoid traces that might link back from a hidden service.
I think there is an appetite for this out there and I'm not sure there is really any place that has functioned in this way since the altcoin invasion and bitcointalk refused to leave the noughties.
Tutorials and help requests with bounties are a great use case for Stacker I think.
