  Digital health, an emerging field integrating digital technologies into
healthcare, is rapidly evolving and holds the potential to transform medical
practices. Blockchain technology has garnered significant attention as a
potential solution to various issues within digital health, including data
security, automation, interoperability, and patient data ownership. However,
despite the numerous advantages, blockchain faces several challenges and
unknowns that must be addressed. This systematic literature review aims to
explore the challenges of blockchain applications in digital health and provide
best practices to overcome current and future roadblocks. Key issues identified
include regulatory compliance, energy consumption, network effects, data
standards, and the accessibility of the technology to stakeholders. To ensure
the successful integration of blockchain within digital health, it is crucial
to collaborate with healthcare stakeholders, pursue continued research and
innovation, and engage in open discussions about the technology's limitations
and potential.
