This is a great idea if you can get it off the ground. Supply Chain Financing has a huge market. Greensill is launching an Early Payment Program where invoices are paid out early. The invoices are funded for early payment by being traded on a futures type market. Its a win,win,win because the payee doesn't have to wait 30,60,90 days to be paid, the payer doesn't have to get financing to pay the invoice and Greensill makes a cut.
I wouldn't be surprised to see a company like Greensill invest heavily into something like this,
Well, then Populous better be a fast mover in using the blockchain for this, or else risk losing out.
