The blockchain became famous for its application through the cryptocurrency Bitcoin. Its main purpose is to solve the problem of using third-parties for transactions between two individuals, which means that it is not supposed to have full control of the exchange. With a growing number of services and companies relying on the blockchain technology, a lot of sectors such as banks, healthcare and law, are set to be impacted in the near future. When applied to healthcare for instance, the patient could soon have full control over their data which would make it easier to share the full data with any health specialist. This raises the question: is the blockchain technology mature enough to be applied in all fields?
