Lastly, Blockchain is generating cost-efficiencies through self-managed networks, enabling secure and error-free peer-to-peer connectivity for vast numbers of loT devices. Industry analysts estimate, for example, that by 2020, 50 per cent of all new operating assets will be self-sustaining (IDC, 2017). Cloud computing infrastructure is a key enabler for loT, Al, BDA and Blockchain solutions, but in many developing economies, infrastructure deficiencies hamper the uptake of such solutions. The lack of supporting infrastructure, such as Internet exchange points (IXPs), reliable and inexpensive electricity supply and robust fibre-optic backbones, affects the deployment of national data centres.
