- What is the purpose of this project?
- Is there a real use/benefit to anyone in their daily life, outside of the crypto-nerd world?
This project has no relation to Etherium at all. Etherium is a platform for Smart Contracts and Decentralized Applications. Radium has nothing to do with it. Radium is about using blockchain as decentralized records/documents storage and tools for verification/identification. You can find some real life use cases in this post https://bitcointalksearch.org/topic/m.13672193
Another crypto with similar functionality is Factom, they have some cool videos you can check if you are interested how this can be used https://bitcointalksearch.org/topic/ann-factom-introducing-honesty-to-record-keeping-850070
Factom is far more mature project while Radium offers more capabilities and more advanced functionality.
