In the business world as well as the media, blockchain is still a hot-button issue. Although many people have heard of blockchain, they may not be aware of its nature. In its most fundamental form, a blockchain is a data structure that makes it possible to create a digital record of transactions and share them across a distributed computer network. One of the main benefits of blockchain is that it builds trust between parties who share information.

Blockchain can be beneficial to insurance companies, banks, hospitals and even governments that have a lot of stored records and need to move and share information.
