This brief essay explores a key but often overlooked hurdle to using blockchain solutions, which is the complexity that decentralized solutions necessarily introduce. At times, the benefits of such solutions appear to exceed the added cost of complexity but often they do not. With this tradeoff in mind, the paper considers two use cases, digital ID and health supply chain management.
Increasing attention is being paid to the potential of blockchain technology to address long-standing challenges related to economic development. This paper provides a clear-eyed view of the technology’s potential in the context of development. It focuses on identifying the questions that development practitioners should be asking technologists, and challenges that innovators must address for the technology to meet its potential.
