A rich interconnect web of currencies could be used to provide incentives and discounts for positive behaviors like using public transportation, recycling, exercising, and sharing resources with others. People may receive tax breaks, lower loan rates, or discounts on insurance by tracking behaviors through connected devices and currencies, and trust earned in one area like hosting guests could help access tools from others. When currencies are interlinked, it opens up possibilities for transparently seeing environmental impacts and incentivizing sustainable choices.
