So, at the moment I am reading about Ethereum and Golem in,
Blockchain Enabled Applications—Understand the Blockchain Ecosystem and How to Make it Work for You
by Vikram Dhillon, David Metcalf, and Max Hooper
ISBN: 9781484230800
And I am noticing that it wouldn't actually be very hard to publish code to solve a problem in a Steem blog post and to offer payments and/or upvotes as a reward for other accounts to run the code and reply with their answers.
A whole new use case?
