Salt is one of the national strategic comodities that has an important position in Indonesia. It is,  among others,  the basic needs of society and also for industry. In the field reality, the number of data on the production process and supply chain of salt processing is massive. Up to now, data on salt production and supply chain flow have not been wellrecorded . Therefore, it is difficult to evaluate the total amount of salt production in Indonesia. Salt farmers gain lack of information about opportunities to choose the middlemen or the factories that can provide competitive prices. It is the time for salt farmers to utilize a digital system to carry out salt sales activities from their land. The reactivation and recovery program for Small Medium Enterprises (SMEs) by the Indonesian government in assisting SME through digital transformation programs needs to be supported. The purpose of this paper is to develop a conceptual model of digital supply chain system to help salt farmers adopt and utilize digital systems more easily. This far, there is no research that discusses the e-supply chain system with block chain technology in the salt business yet. For this reason, the model are expected to contribute to share knowledge about a new supply chain system that can be adopted by salt farmers.
