How is Populous gonna deal with all those thousands of invoices that will all have to be controlled? Who is gonna be responsible if the borrower is not gonna pay his debts?
I know that tokens are safe in the contract but who is gonna deal with all these probably millions of invoices coming in over the next years?

Veritaseum concept is ok for me cause customers buy with their bank-accounts BTC --->ETH --->Veri. They dont need a huge infrastructure.
