The application of blockchain for halal product assurance: A systematic review of the current developments and future directions

The demand for halal product assurance has increased recently at the global level due to the increase in users' awareness as well as the Muslim population. Consequently, the demand for halal certification service by the product manufacturers is also increased. However, the conventional halal certification model is unable to support the increasing demand for certification services in which it does not support the halal industry efficiently that makes the certification process costly. Technological support, particularly blockchain, can facilitate and simplify the halal certification process, which leads to an automated and more efficient process. Blockchain for halal product assurance is considered a new multidisciplinary field; hence, there is a need to gather and synthesize the current information about the field of study in a thorough and unbiased manner so that a more general conclusion can be drawn as well as providing preliminary information to encourage further research in the field. Therefore, a systematic review was conducted to identify, evaluate, and interpret research and developments relevant to the implementation of blockchain technology for halal product assurance. The result is expected to cultivate new studies that can improve the entire process for halal product assurance.
