The current trend in supply chain development requires the application of new knowledge to meet the challenges posed by new technologies. One such technology is blockchain, which facilitates supply chain solutions through the use of innovative data transfer, storage, and verification systems. However, the use of blockchain can be challenging for certain stakeholders, such as small carriers, who may lack the necessary technical expertise or access to the technology. In this paper, we explore the potential for engaging small carriers that provide services within the blockchain supply chain but face technological barriers. We identify the technological barriers and opportunities for these carriers to participate, focusing on a case study of a small carrier that transports temperature-sensitive cargo. As one of the innovations, we proposed a classification according to three types of control levels, which are of fundamental importance in blockchain applications. In addition, we tested in-vehicle temperature measurement for use in cold chains and stored the transaction in a distributive ledger application in blockchain.
