WhenHub proposes to build a mobile app for connecting consumers to experts of all kinds via two-way video streams, text, audio, or in person. The app will be part of a larger service ecosystem called the WhenHub Interface Network (WIN) (Patent Pending). The service will use dAPPS (distributed apps) running on the Ethereum blockchain to create secure micro-contracts – that can be as short as 15 minutes – as well as to provide frictionless billing and payment service. At the end of each micro-contract, payment in the form of WHEN Tokens will be automatically transferred to the expert. No paperwork or billing is involved.
