It may not be necessary to put personal/business details into the blockchain to threaten privacy. See, for instance, the paper "Evaluating User Privacy in Bitcoin" (

But again, the level of privacy that a ledger achieves will depend on the specific use cases that it has been built for, so we just cannot say now whether it would or would not be private. And that is precisely my point. Once there are specific proposals and use cases, whether or not privacy is achieved should be taken into account.

As I said, if you don't want the world to see your personal/business account details​, simply don't put them in the ledger. That's the privacy-preservation mechanism. The ledger won't know anything about your personal details unless you feed them to it. A ledger in the historical sense is a book. An empty book has no information until somebody writes information to it. The author should not be concerned about who's going to read the book. If the author has something to hide, he should not write it into the book.
