Thank you for the video, @marketingmonk

Some thoughts from myself after viewing it:

* Quite (/very) worrying the problem with healthcare institutions.
* I can see the blockchain being used to compare one student homework (=block) to another one, just to detect plagiarism. Nice.

Another use-case I have just spotted could be those exams which must be ansered into a page full of A, B, C, D letters and where student has to circle the correct one (and sometimes make a cross when he is wrong).

Someone could develop an smart contract which just compares the answers to the correct ones. Contracts will always do what they are told to do, and the message from the student to the smart contract will probe that the exam was done.

If the exam is done in a class room, then even there is real person identity.

* The problem with privacy on elections

I am in a polytical party where we make lots of elections in order to make our own decisions. Everything is private and anonymous. However, votes are stored in the polytical party server. Those votes link the username to a real world person.

By using the blockchain technology, the party could save its own resources.

If someone voted, the vote will be on the blockchain forever and ever. That's great.

But: what about privacy. What about keeping someone's vote secret? Bitcoin-esque blockchain is not private. The same for Ethereum. That would bring us to CryptoNotes-compatible tokens, like Bytecoin, Monero, or my favourite one, DigitalNote (XDN).

Interesting, anyway.

* Digital rights **ownership**

Here I will write something on my little blog (sorry, I am a newbie on Steemit), but it will be in Spanish, with no translation planned. However, I am going to say here what I will develop there: smart contracts which distributes the amount of revenue that belongs to each owner.

this is spot on!

You have great blogs keep it up & keep'em comN ;)
