Populous’ main advantage is lower fees versus traditional marketplaces like Inwise. Small businesses can sell their outstanding invoices at a discount in exchange for immediate cash. Buyers evaluate the details and bid on the invoices.
Populous has 2 tokens called Pokens and PPT (Populous Platform Tokens). Pokens are stablecoins, which has a pegged price (e.g. 1 Poken is equal to 1 USD). The Poken is an ERC-20 token used to purchase invoices.
PPT is also an ERC-20 token used as collateral for invoices. When investing in an invoice, PPT must be put up. Once payment of the invoice is completed, the PPT is returned to the investor along with any Poken profits that were generated.
