Cost Benefit Analysis for Blockchain-based solution


Hi, I am conducting feasibility study for Government Open Data blockchain-based solution. So far I am assessing 3 options (traditional centralised solution, public blockchain-based solution, private/consortium blockchain-based solution). I need to perform cost benefit analysis for all of the options, however it seems little bit difficult to analyse costs and benefits of the blockchain-based solutions in comparison to traditional IT solutions/systems. Is it possible to find any guidelines, best practises or economical models for this kind of CBA?

    almost impossible. needs total rethinking. especially with DLT tech cost are usually distributed to third party who for economic logic want to profit from upholding the infrastructure.
    Thx for your answer. Just for clarification. By “almost impossible” did you mean, that it’s almost impossible to use DLT for open data solution or it is almost impossible to conduct CBA comparing 3 options mentioned in my post? What if tech cost will be borne by government cloud provider?
