Bob is borrowing a $10 item so he and the lender (Lisa?) put $20 between them into a smart contract until Bob’s tired of the item then the $20 goes to GreenPeace or whoever. Minus gas fees. Or maybe GreenPeace only gets the money if Bob makes off with Lisa’s blender and they both get their money back if the blender gets returned, dunno?
