I've personally found one compelling use case, decentralised DNS, I'm sure there are other projects attempting this but the one I'm familiar with is Namecoin[1]

Namecoin would make sense on a technical level if anyone were actually using it, but nobody is.

ENS has existed for a while and has very little traction.

I'm working on a project that is based on blockchain for the key purpose of making the data on it effectively available to all to add to and to consume -- basically providing a public utility for the data hosting.

It's not a path to riches (I can see a possible lifestyle business out of it), it's about giving people new opportunities.

I've been chewing on this for years and only now that Claude has shown up do I have a partner to help me make this work.

I do have some experience working on blockchain for a startup (non-ICO) that helped inspire me, but the experience itself bordered on being PTSD-inducing. The people I worked with were True Believers of Crypto, but the product we were building used crypto solely to tell their investors it was a blockchain company -- not that their product leveraged it at all.
