Blockchain technologies have been steadily spreading across every industry, slowly tackling all the inhibitions that only appear apparent when a potential smoother solution is demonstrated. 

An example is IXLedger, who are demonstrating (among other things) how better to transact and settle business and claims within insurance - an industry renowned for its slow and non-digital interactions.

Within energy, we have since the beginning of the century had a 10,000x increase in electricity exporters; pretty hectic - Electron is tackling this by using decentralized technology to advance the shared infrastructure of the energy markets by supporting the industry's transition to a smart grid infrastructure and the latest market initiatives.

The outcome is obvious - a trusted, open and more efficient solution BUT so far - real use cases are more theory than PoC and the real battle seems to be in convincing the industry giants to encompass the new efforts.
