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 block chain education, supporting research initiatives, and promoting innovation in Tanzania.
