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

Games & game leaderboards, blockchain because interoperability

Working for the Superchain 🔴🔵🟡🟠🟢🟣

Yes, we don’t need a public blockchain for this, but the incentives are massively more aligned with consumers if it operates on one

Don't need the entire world to come to consensus, though, just need interoperability between game engines etc.
