The very first thing in your list is literally a central authority.


It certainly should be, and this is no problem in developed democracies. Not so much in the developing world - leaves room for corruption.

and btw look at Estonia - implemented blockchain for most of its govt stuff - including judiciary, and they are among the fastest in the world in terms of time to resolve matters once they reach the courts

Imagine how impossible it becomes fix a wrongful conviction. You could never fully clear that persons name because the “crime” would forever be on the books publicly


True, it’s not something you can apply everywhere. But there are use cases where the downside is virtually nil.


Well yeah, blockchains are inherently doing what governments historically have done but in a safer, more scalable way. Anything that is just a public record that needs to be kept is a slam dunk for blockchains.


What is "safer, more scalable way" about blockchain?

Safe? There are many solutions to maintaining reliable records. Blockchains are one, but no better than many others

Scalable? I cannot understand how it is possible to think that scalability is a attribute of blockchains. A centralised blockchain is no less scalable than many other cryptographic solutions, but a lot more bother. Distributed blockchains are not scalable at all, are they?


On Safe: Smart contracts ensure only the right people have read and write access to the data with no way to cheat. The records are also safe in case of hardware failures so there's no way the data can be lost in an accident.

Scalable: There are a few aspects of scalability. The one you are referring to and what most people think of is number of transactions which is indeed limited right now but for most data is good enough, especially with L2s like Optimism and zero knowledge rollups. The other aspect is social scalability. If you want a system of records to be available to more people then the organization running it is the ceiling for how widespread adoption will be. A birth records system for Peru will never be used by Brazil, the US, or anyone else. For a system to scale larger than a single country then it needs to be credibly neutral where no person or organization controls it and everyone can trust that the system is fair. That's the kind of scalability that smart contracts offer. Worldwide systems that scale to anyone who needs to use them.
