It’s an admirable effort, but there are some key omissions, first and foremost the price paid for the coffee, which is not shown in the blockchain ledger. Secondly, the suggestion that “fairness” or some vague concept of supply chain equity is bolstered by blockchain seems unfounded. IBM and Brooklyn Roasting show only the Fairtrade premium-associated investments back into the coffee-growing community — investments made in 2016, with or without blockchain technology.

So while opening the books is commendable, the opening itself is by no means a solution to deep-rooted problems affecting the equitable trade of coffee.
