Abstract Although a number of studies focus on using the blockchain technology (BT) in various application aspects, there is no comprehensive survey on the blockchain applications in maritime shipping supply chain. To fill this gap, we conduct a comprehensive blockchain applications and future improvements survey, and empirically evaluate its effects on intention to use. The results suggested that customs clearance and management, digitalizing and easing paperwork, standardization and platform development dimensions positively affected intention to use. In particular, this paper gives the maritime shipping blockchain-based digitalization also points out the future improvement directions in the blockchain technology.
