“A merchant can withdraw from your lightning node using the invoice_request and then return change to you back using the offer on the back side. Just like paper money, these can be denominated in different units. You risk that the merchant will actually give you change, but the same thing happens with paper money. The main drawback with Lightning Cheques is you don’t necessarily know if you’ve been ripped off and never got the change until you go back home.” https://delvingbitcoin.org/t/lightning-cheques/1162 🧐 #bitcoin
