A decentralized marketplace that's like Amazon.com but without Amazon. Creating an easy software solution to bring the inventory of every brick and mortar store online for cheap quick delivery or pick up. The ability to track/authorize orders so if someone bought an iPhone and they wanted to resell it, they could relist it on the marketplace as a used item with one click.
Some state of the art trust system between manufacturers, sellers, service providers, and customers. The ability to police counterfeiters and scalpers. Manufacturer says they created 10,000 and they sold to these parties and you can trace the supply chain from manufacturer to customer.
