Perceived Usability of a Blockchain Lab for Blockchain Learning, Research and Innovation in Tanzania

Abstract

Blockchain technology has gained global attention for its potential to transform data management
and service delivery across industries. However, adoption in developing countries, such as
Tanzania, has been limited, largely due to gaps in knowledge, technical skills and accessible
training environments. To address this challenge, Dinari, a blockchain learning lab, was developed
to provide users with a platform to explore, practice and apply blockchain concepts in support of
education, research and innovation in Tanzania. The study evaluated the usability of the Dinari lab,
using the System Usability Scale (SUS), a standardized instrument for assessing user experience. A
total of 112 participants engaged with the lab and completed the SUS questionnaire. The platform
achieved a mean score of 72.4, which falls within the good usability range and is above the average
benchmark of 68. The study concludes that the lab can play a valuable role in advancing
blockchain education, supporting research initiatives, and promoting innovation in Tanzania.
