I've been around blockchain and decentralized systems since early 2016. Professionally and in my spare time, and I have never found any project I could say: "Yes, this is useful and could not be done without this tech" or "This tech makes the project that much better"...
So, my question today is, do you know of any web3 or blockchain project that you would say it's useful and could only be done with this tech, or at least it adds value?















While I totally know what you mean and I really wonder what people are building of value, I have a case I'm considering right now.
I'm making a system that records the maintenance performed on equipment to ensure that it is kept up to date with legislation. I'm currently looking to record a hash of the database records in a blockchain to validate that the data has not been modified, this should stop unscrupulous individuals from avoiding fines by reinventing the past and reduce the cost of chasing paper trails to validate records. It's the only way I can think of ensuring that there is a full record of modifications to something that no one can change.
