At the invitation of the Tuvalu Ministry of Justice, Communication and Foreign Affairs (MJCFA), Monash University and the Oceania Cyber Security Centre (OCSC) work together to provide the Ministry with scientific support to the existing Tuvalu National Digital Ledger project. The ultimate goal of this project is to provide the Government of Tuvalu with scientific recommendations on the way forward as Tuvalu embarks on a new journey towards digital transformation.

We have conducted a series of workshops with the Minister and MJCFA team in 2021 and 2022 to inform this evaluation report. In this report, we performed a systematic evaluation of the state-of-the-art solutions for national digital ledger systems. To establish the evaluation framework, we identify necessary requirements of these approaches, where the requirements concern four aspects, namely the required functionalities, the control of the government on the approach, the performance, and the cost. We classify the state-of-the-art solutions into three types, and performed a comprehensive evaluation on the possible technological solutions.
