Technically speaking, #Nostr protocol can be expanse with NIP, as the current internet can be expanse using RFC or #Bitcoin throught BIP
So, #Nostr might be expanse for other L1 payment.
However, you can't zap/tip anyone with a L1 chain. Even with #Bitcoin. It's the #LightningNetwork, builded upon #Bitcoin, who can sustain many fast and small payments.
