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
