Blockchain technology is a distributed ledger digital system that records all transactions on a network of interconnected systems in a way that is impossible to edit or hack. Thoughts of cryptocurrency pop into mind when blockchain is mentioned, but blockchain holds vast possibilities in other facets such as big data analytics, research, the Internet of things, healthcare etc. Blockchain technology has many practical applications in the healthcare sector, including precision medicine and interoperability, supply chain management, exchange of health information, security and authorisation, all of which are pivotal for effective health systems and quality health services. Inadequate infrastructure, lack of funding, computer literacy, and poor government policies have been the significant hindrances. The challenge of establishing blockchain technology must be addressed. Exploring its architecture in the Estonian healthcare-based system, the possibility of its deployment in the Nigerian health sector is feasible with the right approach and government policies. By discussing the potential benefits of blockchain in the health sector, the obstacles that impede the adoption of this technology and the recommendations to overcome them, this perspective piece aims to create awareness and close the wide gap between this idea and its implementation in our healthcare system. This will improve patient outcomes and strengthen our healthcare planning and management system.
