What's the cost-formation model of using RGB?

TL;DR

RGB protocol leverages the same fees that are present in Lightning Network, not adding any additional fee to them. If you use RGB, you'll need to pay same fees as you normally do while transaction in Bitcoin.

Today there are 2 kinds of fees in LN:

1. The first is basically the fee of the transaction itself, for it being published. This fee is attached to every transaction and this is a part of the channel that you open. It can be paid by you, by the other party, or being shared between you both.

This principle and this fee stays in place for RGB transactions.

2. The second is the routing fee and it is paid when you do assets (satoshis in this case) routing.

This fee also remains the same in RGB, but with an additional option of paying it not only in bitcoin/satoshis, but also in the RGB asset that you are doing this routing of.

RGB DEX routing fee

Important to notice that on top of the RGB protocol there will be DEX functionality added, that would allow you to exchange one RGB asset for another. Thus, each node that is willing to do the exchange will be able to set up a fee for its exchange services and you as a user that need to will need to either accept and pay it or find a different node with a different fee. Consequently, if you are a node operator, this gives you an opportunity to monetise your node.
