I’m all for the central database. To enter data into it the government will appoint an agency which in turn will appoint individuals after they pass exams or get their license. The said individuals will have to fill in regular reports that had to be somehow processed and analyzed. Also each such individual required to keep records in a safe manner, sometimes this means hiring a security and a compliance officer. At this point it is not clear if the cost of maintaining the agency and all that people is less than automating the agency of the blockchain.
the only difference between centralized databases and blockchains is the property of trustlessness. everything else can be done much more efficiently by normal databases. if you dont need trustlessness then you dont need blockchains
This is just one half. The other half is blockchain and smart contracts also replace all the people involved in controlling access to a central database. I can imagine a smart contract that would allow me to transfer ownership of my car to you and get paid in return. I cannot imagine an API to a central database that can do the same. One thing you can do to defeat my point is to show how such an API can be built.
if you trust the court, why not just have them store everything on some mysql database and execute all the ""smart"" contracts as regular java code? blockchains are necessarily orders of magnitude worse in terms of performance. why do you want to use an extremely slow linked list based DB?
