Post examination malpractice has continued to show up in some of the marking centres at grade twelve (12) level, which is mostly the changing of grades already entered in an electronic system. This study was designed to investigate the current challenges that are poised by the current system in the entry and transmission of results from marking centres, through a mixed research study approach. To the challenges presented by the current system, a Blockchain technology approach was developed to address the challenges. The Blockchain system would use the cryptographic hash function known as SHA-256, to enable the system compute the correct input value given some output value. The function proposed because of it’s collision resistance capability. The transactions between the marking centre and the examination council is a way of recording activities occurring in a digital form on the Electronic Results Management System (ERMS).
