> for sure it's awesome to have tamper proof asset registries on the blockchain that are compatible worldwide

For one thing, the blockchain doesn't provide tamper proof asset registries because the blockchain can be forked (see the DAO fiasco for proof).

Second "temper proof asset registeries" aren't actually a problem that really needs to be solved. The hard part of any registry is making sure the data that goes in is valid.... and that is a meatspace warm-fuzzy-human problem, not a technical problem.

The "DAO fiasco" and Ethereum Classic is, in fact, proof that you are wrong about the lack of tamper-proofness.

there is no contentious forking if it's true decentralization. But this is more of a thing if governments would participate and run nodes along with anyone that would like to attest too.

I don't believe in the saying that you need a problem to be solved. For sure the country I live in now cannot lookup easily what other real estate properties I own in every part of the world. All governments would need to select a distributed database and encode everything on it. Well this is now called Ethereum or insert your favorite platform here and they will develop on it because the technology makes it easy.

oh, you mean a dictionary object containing a hash of the properties of the previous dictionary object?

Sooo innovative...

show me some dictionary objects that are replicated in computers in all parts of the world to keep them tamper proof and I will give you one satoshi

It's awesome until your private key gets stolen and suddenly a hacker in Russia owns your house.

how do property title considerations currently work?

what keeps a Russian from stealing your house today?
