The Internet of Underwater Things (IoUTs) has opened the door for developing smart ocean applications, and the Internet of Things (IoT) has expanded to encompass a variety of ecosystems. IoUT system designers must overcome significant challenges, such as handling large amounts of data, protecting sensitive information, and reducing energy and computing expenses. To overcome these difficulties and improve the scalability of IoUT systems, this work investigates the combination of blockchain and InterPlanetary File System (IPFS) technology. The main objective of this research is to use IPFS and blockchain technology to protect the transfer of IoUT data as well as increase energy efficiency. Additionally, three essential qualities should be properly addressed to develop a secure and reliable IoUT infrastructure: scalability, security, and energy efficiency. Our research conducted experiments to evaluate the efficacy and usability of the proposed solution using a case study technique. The assessment focused on the performance of query responses and algorithmic execution, ensuring perceptions of the effectiveness of the integrated system. The results demonstrate that our approach successfully reduces energy consumption by 21% compared to the LEACH algorithm, highlighting its efficiency in prolonging device operational lifespan in underwater communication systems. Furthermore, the integration of blockchain technology ensures data security by maintaining integrity and traceability. The proposed solution provides a structured approach for building energy-efficient, robust, and secure distributed IoUT systems, offering practical guidelines for improving underwater communication security while ensuring the integrity and confidentiality of transferred data.
