PayPie is developing a decentralized risk scoring solution and marketplace for invoices. PayPie will allow users to buy and sell invoices, and give companies an alternative funding solution for their immediate cash flow needs.
Paypie has a strong focus on usability and will integrate financial data from QuickBooks Online to encourage adoption.

The network will be powered by the PPP token.

GXChain allows users to take greater control of their personal data and creates a blockchain-based marketplace of data. Unlike centralized data centers, the GXS marketplace provides more privacy through encryption and allows users to profits from access to their data. GXChain's platform allows users to generate a unique digital identity and manage their personal data through the Inter Planetary File System (IPFS). Users can then monetize this data according to their preferences and well defined smart contracts. The network features an innovative hybrid consensus mechanism that combines Delegated Proof of Stake (DPoS) and Proof of Credit Share (PoCS).
