On the note of using blockchain for other use cases than Bitcoin, I found these two articles that throw a wet blanket over the blockchain-but-not-bitcoin hype:

"Blockchain consultants have built prototypes for stock trading, asset registry, voting and payment clearance. But none of them have been commercially deployed because they are more expensive than simpler methods relying on established database and software stacks, as the government of Vermont recently concluded."
