I got it💡 Let's name it "Self-Custody In Name Only," or "SCINO" for short. It's right in "Andreessen's Law of Consumer Internet". It must be helpful to be the bridge from custody to self-custody for grandmas in the stairway to heaven!
Just in time my raspberry pi broke, so I switched Bitcoin Core with LND to Knots with Core Lightning. Also I moved AlbyHub out of the raspberry pi and onto fly.io, while being powered by Cashu. And I'm posting about it now on Nostr.
It's all #DECENTRALIZATION by a minority with less than 10% market share!
Probably this can be understood by nostr developers here more than pure bitcoin developers. Because passkey is used as "identity by public key", and cooperates between a merchandise site and payment gateway services.
Imagine replacing Passkeys with Nostr and replacing MasterCard with Bitcoin. The 3-layer structure of merchants, payment gateways, and banks would be reduced to at least 2 layers (bank out), or just 1 (only merchants).
From creditcards vs bitcoin to creditcards×passkeys vs bitcoin×nostr
NOTE: This framing may be too simplistic. Other combinations such as Nostr and Passkey, payment gateways and Bitcoin, or passkey and Bitcoin(!) may work together.
