I can’t find the case study, but this blockchain project by IBM was implemented in Singapore and was shown to reduce customs processing times from several weeks to just several hours.

the real question is what part of this was specific to blockchain, something that would be difficult or impossible to do without it. if you want to put forward this argument you need to at least provide a simple, clear, coherent answer to that.

in this case, i could easily argue a sqlite db hosted on gitea would work better and theres no way to prove im wrong.
