A blockchain-enabled vaccine register. This dApp illustrates how a credible vaccine register (e.g. for use during pandemics) can be created on the blockchain - blockchain serves as a single source of credible truth and anyone (any authority, entrance marshall etc) can query the blockchain to see if a claimed vaccination ID is legitimate.
