## What is MedBlockChain?

The goal of this app is to educate what a blockchain is, how it works and demonstrate a pharmaceutical application for which it can be used for. 

The significant advantage of making this as a teaching app is that the user can play around with the parameters and see what each action does to the blockchain. The user can also explore the chain by pressing the buttons and see what each component is made of (similar to an anatomy app).

Each screen shows a point of view for the manufacturer, patient or regulatory authority. The proof of concept is a proposal of a "CHECK IN" and "CHECK OUT" system in a blockchain and shows the power of this technic in the battle against falsified medicine. 

There is no crypto-currency involved. It's a local chain built every time the app is loaded, no data is stored permanently. 

The primary target is the scientific community such as scientists, teachers, and students.

The secondary target is people interested in learning about blockchain and other use case scenarios than currency.
