No, hay varias restricciones para que el servidor colabore con la firma de una transacción.
Ej, se permite una única sesión activa: si cambiás de teléfono, al sincronizar tu wallet en el teléfono nuevo, no se van a permitir pedidos de firma desde la wallet del teléfono viejo.
Totalmente!
Ya le dimos un intento, pero no pudimos llegar a una UX suficientemente buena: resulta que RBF tiene mil casos borde en donde no funciona.
Ya volveremos a atacarlo con más infraestructura preparada para manejarlo bien.
Muun is a non-custodial wallet. That means that the destination pubkey is a key controlled by the mobile device.
Muun node is the second to last node in the payment route.
In Blue's case the money goes to their server's node, so it's the last node in the payment route.
Not sure what you mean.
If you always use the same destination node pubkey it's trivial to link different invoices to the same identity.
The muun node is just an intermediate node in the payment route.
You can't link any two invoices to the same identity.
This is especially important since many exchanges are linking lightning invoices to real world identities.
The client node pubkey rotates with every invoice, to preserve client's privacy.
Muun nodes only appear in the route hints, so that payments can be routed via the private channels to the client node.
It is! You can independently sweep all of the funds at any time (unfreezability), and Muun only has one key of the 2-of-2 multisig (unseizability).
We spent two years improving the submarine swaps, so there are a bunch of different optimizations in there.
Main benefit is lower fees.
It can be done with a spotty connection as long as the channels aren't used to route 3rd party payments.
That is, mobile lightning nodes are leaf nodes.
The first (last) hop of every outgoing (incoming) lightning payment is a very optimized submarine swap.
All inbound liquidity is provided automatically by Muun server nodes.
We are working on transitioning from single-use payment channels (aka. submarine swaps) to full channels
Yes!
All funds, whether received on-chain or via lightning, are in the sole custody of each user.
Funds are protected with 2-of-2 multisig security and users have possession of both keys.
Muun servers run their own nodes that forward payments to the mobile device nodes.
