Do you consider cashu a bitcoin layer 2 or layer 3? Or is it not a layer at all? #asknostr
Discussion
Its a btc alt whatever it is. No hate. I use it. But its an alt
I would say it can actually be both, L2 and L3, but usually implemented as L3.
Current thinkingā¦
Anything not layer 1 = layer 2
Layer 3
I would consider Esats an L3 as its dependent on L1 and 2 to function, but Ecash as a separate system. Cashu happens to support both.
It's sprinkles, or frosting. Not a layer at all
It's a Layer 3 - very similar to Nostr's NWC. Both Nostr and Cashu are messaging protocols that allow L2s (lightning wallets/nodes) to better communicate to vastly improve the bitcoin payments experience.
Layer 3
Uses ā”ļø for the fast settlement layer
Cashu has unilateral exit to ā”ļø
ā”ļø has unilateral exit to āļø
Layer 3, along with Fedi & custodial lightning providers like WoS.
It's a layer 69
L3
