This document discusses implementing IOTA solutions on embedded devices for Internet of Underwater Things (IoUT) systems. It presents the IOTA Tangle and Masked Authenticated Messaging (MAM) as supporting technologies. It then describes the methodology of performing a feasibility study, reverse engineering the workflow, and implementing a pure C version to integrate with embedded environments. Test results show execution times for fetching data and code size. The document concludes the proposed solution enables IoUT and outlines future work including optimization and additional IOTA features.
