View reference transactions on the Ethereum blockchain

Recording references on the blockchain ensures they are stored and authenticated in a transparent and trustworthy fashion—permanently—so that they only need to be recorded once and candidates can reuse them throughout their careers. Candidate reference data is verified and cannot be accessed or changed by anybody else including the Zinc team.
