Blockchain as an enabler for public mHealth solutions in South Africa

Blockchain technology underpins a radical rethink of information privacy, confidentiality, security and integrity. As a decentralised ledger of transactions across a peer-to-peer network, the need for a central third party intermediate verification authority is disrupted. To unlock the potential for mHealth, the need for authentication and verified access to often sensitive data, specialised services and transfer of value need to be realised. This paper interrogates current processes and aims to make a case for Blockchain technology as an improved security model that has the potential to lower the cost of trust and an alternative to managing the burden of proof. This is particularly relevant for mHealth that, by its nature, is often a distributed endeavour involving the goal-orientated collaboration of a number of stakeholders.
