Coca-Cola is playing a major role as part of a pledge to conduct 28 national studies on labor and land rights for its sugar supply chains before 2020. Ideally, this tackles complaints that it and similar companies fail to protect workers' rights at every step. The State Department will offer its experience with labor protection, while Bitfury Group and Emercoin are producing the blockchain platform itself. Blockchain Trust Accelerator is a non-profit aiming to use its namesake tech for social good.

The pilot already has its limits. Blockchain can persuade companies and governments to respect work contracts, but it can't make them respect those contracts. Also, blockchain's digital nature raises some implementation questions: how do you ensure that workers can access their info when many of those affected might not even have a smartphone? The project is still young, however, and this could still represent an improvement over a modern employment system that frequently lets companies abuse workers with relatively little consequence.
