Guardtime, a startup that uses technology similar to that underpinning bitcoin to secure public and private data, has signed a deal with the Estonian government to secure all the country's 1 million health records with its technology. [businessinsider.com]
Guardtime uses blockchain technology, made famous as the underpinning of bitcoin, to verify data and prove that it's trustworthy. It has created a network that citizens, private companies, and the government can also access to verify information on it. While similar to bitcoin's network, it is distinct and in fact predates the original white paper on bitcoin.
