By principle a decentralized application cannot be controlled. Usually a set of economic incentives are designed instead, guiding its evolution towards a chosen goal. In supply chain that goal includes complete and correct data, but the incentives that take the solution to this desired state also require making data publicly available, which is understandably a difficult choice for private corporations.
In this article I want to discuss how a supply chain blockchain solution can ensure the accuracy of the data contained at the expense of privacy. This understanding is critical for architects and business leaders considering blockchain technology.
