ABSTRACT
Blockchain is a new type of digital architecture, consisting of a shared, immutable ledger that can better ensure the resilience, provenance, traceability, and management of health data. To understand blockchain’s potential for healthcare, we first need to understand some basic technical elements. Blockchain data is also secured through cryptography so that participants can trust that ‘blocks’ of data are authenticated and verifiable. Blockchains can also enable other technologies such as distributed applications and smart contracts as well as the use of cryptocurrencies. Blockchains can also act as a digital backbone for other technologies able to interface with blockchain systems such as cloud computing, artificial intelligence, eHealth and mHealth devices/applications, and the broader Internet of Medical Things.
