Decentralised applications represent a step change in the way companies will buy user and machine data in the future. Centralised data stores are easier to attack and the value of the data is realised by only a handful people who ‘own’ the data but who did not create it - think YouTube and Facebook. 

IOTA is one company leveraging distributed ledger technology to create a market for data generated by connected devices and embedded systems where the owners of the assets can sell their data on an open market. The market will be accessible to large businesses and to the man on the street. If businesses want to access data from your watch, fridge freezer, smart meter or car, then IOTA will allow you to charge companies for access.
