Here are example from Canadian government using blockchain to track everything.
1. NRC-IRAP - Blockchain publishing prototype. Although it is still a prototype, but you will get the importance of using blockchain specially in government sector. I think one advantage is that everything is transparent, as in this case. For Thailand though, it will be easy to track and even tax payers can have access to that private ledger so that they can check if they have paid the right tax or have tax refunds. Or if tax payers will not have access, at least those tax collectors will have a central repository to look at and they can easily chase those who are not paying tax. Their job could well be very easy.
