Thank you for sharing this perspective on blockchain technology and its potential to improve pharmaceuticals and supply chain management in developing country settings. Supply chain management is indeed one of the most complex of the building blocks of any health system. Stock-outs due to poor quantification, procurement, storage, and distribution (particularly last-mile) are rampant in developing country settings. Blockchain technology is indeed a game changer in addressing these very chronic issues in supply chain management. I hope that the Bank can help to bring the benefits of this new technology to scale in developing country settings.
