Populous is a peer to peer blockchain based platform which helps small and medium sized businesses. They help these businesses participate in invoice financing. Invoice financing is when a business takes a loan against bills which are due by its customers. The whole system runs on a system of smart contracts – contracts which are executed by the blockchain. There is however, an administrator who determines if businesses can register themselves on the blockchain. The admin takes into account the Altman Z-score formula which helps analyze the stability of a business. It is a faster way of finding invoice buyers and sellers. The whole system is secure because all invoices are uploaded to the Ethereum blockchain.
