This reminds me the idea of using the blockchain to implement land registry in Bolivia, Peru and Paraguay. Some Swedish startup came with this idea, I guess.

But if the legal authorities there aren't reliable/competent enough to implement a land registry why would they be reliable to enforce a blockchain-based registry?

- "This blockchain says this land is mine!"

- "This gun says get the f**k out and that police officer I bribed agrees with my gun".
