Factom coin:
"It enables people and businesses to use a mathematically provable “notarization” service."
"We are working on data management applications to ensure that mortgages can be processed faster, cheaper, and within the current regulatory framework. This involves auditing and tracking data collection from many different parties over time about information covering every aspect of a mortgage. Income verification, property history and maintenance, taxes paid/owed, payment histories, property surveys, zoning, etc., all produce many documents that must be reviewed in the course of issuing and maintaining a mortgage.
The third use case would have been particularly useful during the 2008 housing crisis when banks were buying each other and had to merge huge amounts of data which resulted in thousands of documents being lost. That alone costed banks billions but can be easily prevented in the future thanks to Factom. At the time of writing this article there are over 140 mln records, 11 mln entries and 110,000 anchors on the Bitcoin’s blockchain which shows that it’s already being used heavily."
Again, the potential to change industries......and a FYI: Price per coin Jan 1, 2016 was $0.47, price today $78.08.
