Again, it’s not a record keeping problem, it’s a problem with people being able to dispute the records, and transactions being able to be nullified.
The records are public today, and you can go check them. It’s usually even accessible via the Internet.
Part of buying a house is the mortgage company checking all those records, and other ways things can go sideways.
Issues usually aren’t because someone misread the records, but because a record was created that was invalid, or things you can’t record on the block chain, like “back taxes” or “grandma had two wills”.
The block chain doesn’t add anything that a public website doesn’t provide more simply, and it’s just as susceptible to the courts coming in and saying that a transaction was invalid because the estate executed the wrong will, or something like that.
