Workers and employers is what you meant perhaps.
Wow, what a hunt, great, mind-blown. Often contracts signed are on paper or pdf which is not smart. Sometimes workers are not smart and they get fooled. Now, the problem is solved. Blockchain will ensure, no cheating and full meritocracy. Employee will be motivated. Low cost for employers. Win win.
Great token sale though, a random founder, couple of asian dudes, one slick chick, and a blockchain expert. Also, they have a whitepaper which means its a great project!
