I've published Part Two of my research on the blockchain in education. I'm guessing Edsurge isn't going to link to this one, heh, as I call out the dangerous, anti-democratic ideology of "the Silicon Valley narrative," something that is so neatly packed into the blockchain (and in Edsurge too, for that matter).
While I'm at it, I've collected a couple more links to other blockchain-related stories:
Properties of Permissioned and Permissionless Blockchains
Corporates Increasingly Involved In The Largest Bitcoin And Blockchain Deals
Watermarking and Blockchain Challenges
When Bitcoin Grow Up
