Design of Blockchain Implementation for Supervision of Vaccine Distribution: Indonesia Case

Vaccination is still one of the most reliable ways to deal with pandemic outbreak. The vaccine distribution process involves a lot of data from various parties, which must be maintained its validity and security to provide a basis for making the right public health decisions. Blockchain technology can be a solution to secure data and build trust between parties because data do not only hold on one party but distributed to all parties with cryptographic security. This study aims to design an architectural model of blockchain system for supervision of vaccine distribution by taking Indonesia as the case of implementation. It uses analytical study to identify the possible problems and the stakeholders involved. As the result, it proposed the type of blockchain and the architecture that are most suitable for use in the supervision system. By making valid data readily available to policy and decision makers, it can facilitate evidence-based decisions on public health.
