Blockchain technology and decentralized applications (DApps) have the potential to alleviate the traditionally high dependency on centralized, trusted parties for certification of information integrity and data ownership. These distributed ledger technologies (DLTs) mediate transactions and exchanges of digital assets in a decentralized and consensus-driven nature, which allows agreements (ie, smart contracts) to be directly made between interacting parties while guaranteeing their execution. Key properties of blockchain technology, including immutability, decentralization, distribution, replicated storage, and transparency, provide a unique position for this technology to serve as a potential infrastructure to address pressing issues in health care, such as incomplete records at point of care and difficult access to patients’ own health information.
