Halal food is any food or activity that is permitted to be used or carried out according to Islamic rules. This term is used to indicate food and drink that are permitted to be consumed according to Islam according to the type of food, how to process it and how to obtain it. Indonesia is a country where the majority of consumers are Muslims and with the inclusion of many types of food from many countries, it will cause problems related to the halal-ness of the food. Currently there is no system that can be accessed by consumers that guarantees the halal-ness of imported food so that it is difficult for Muslim consumers to obtain valid and renewable information on halal imported food. On the other hand, currently block chain technology has several features that can be used to create transparent, immutable, decentralized transactions and other features. Thus, the aim of the research is to help Muslim consumers get halal food by building a model of the halal food supply chain using block chain technology. The research method uses a qualitative approach through observation to obtain problems regarding the concerns of Muslim consumers consuming non-halal food originating from several countries. Literature studies are used to find alternative solutions with information technology and ultimately determine blockchain technology as the solution.
