It never stuck in my country, I think it did for a while in Sweden for their land ownership systems, but never here. It never stuck because it’s just a terribly inefficient database.
There is a use case for decentralised landownership, maybe not in a low corrupt country like Sweden, but I’m sure you can think of places where total transparency in land ownership and the transfer of land ownership would matter.
The problem blockchain doesn’t solve is that even with perfect transparency, your claim of ownership means nothing to the people with guns. Which means it doesn’t actually help you in countries that aren’t big like Sweden.
The same is true for all its use cases, including money. Because even money relies more on the established system more than any crypto fan will ever care to admit to themselves.
