Blockchain is the technology that sits behind a new kind of database called a distributed ledger. It gives us a much more secure way to store and manage data. Data is shared across a network, and everyone in the network has their own identical copy of it. If anyone changes the data, it shows up in all the copies within minutes, or even seconds. That makes it more difficult to attack a blockchain database than a single one, where the data is all in one place. It’s also harder to tamper with the data, because the members of the blockchain network will immediately spot a change to one part of the database. In a series of papers we explore the benefits of blockchain to the healthcare sector. In this paper we look at how blockchain could improve the prescriptions system.
