Tell me about public blockchain apps that do not involve objective money or objective identity, which require strict global consensus, why they should be built on public blockchains, and why haven't they been built yet? I'll consider writing a post, when I get back to it, to explain why it does or doesn't make sense

a land title registry -- a db of all land, who owns that land, and what rights/liens are associated with that ownership

requires consensus so there are no disputes and so ppl can buy/sell with confidence

needs public blockchain because govts illegally confiscate land

idk if its been built or not

building /cabin, advising /clanker and /farcon | grin.io

if you think this involves money and/or identity, then plz be clearer about how you're using those words here

It may be the de facto system in places where govt trust is low, or may be part of the legal system in places where thats important 

I’m thinking of situations like this

The said land titles follow the laws of the land, though. So, a blockchain will do nothing, unless it's part of the legal system.
