There are a lot of projects offering to pay you for your data. Even today another project was added, I've mentioned it here:

But I don't want to be paid for my data. I want my data to be protected. I don't want google or any blockchain startup to have my data. I don't want my search history to be used against me by advertisment and marketing. Is there a blockchain for this?
