In order to have a trustless system that is able to verify location for smart contracts, Foam is currently developing a spatial protocol that can run on the Ethereum blockchain. This system would give users the ability to verify real-time locations through the blockchain and would be useful in various use cases, including location-based gaming or loyalty rewards programs, supply chains, IOT devices, self-driving cars, mapping functions and applications, and more. Because GPS is easily spoofed, the ability to verify location in real-time adds important commercial value for its users. Despite this, Foam is committed to making their protocol open-source. They have two tracks of development–the first is the spatial index, which they hope to make available to the public by the end of the year, and the second is a pilot proof of concept protocol in order to set gateway nodes and incentivize adoption. Beyond the release of the spatial index, Foam hopes to release a new white paper and website by the end of the year, and begin a token sale in the beginning of 2018.
