You’re coming across as condescending whether that’s your intention or not.

Mistakes can be corrected with a re-recorded deed or a recorded scrivener’s affidavit. All of these instruments have to be notarized, so a clerk will check for a notary’s stamp but these can also be faked or the notary themself can be tricked with fake IDs when they’re witnessing the doc signing. Fraud is what has to be taken to court to fix. And most fraud in a chain of title is going to be pretty easy to spot when doing a title search, but like the original post says, most of the time the owner might not ever notice it’s happened until they go to refinance or sell and the lender or purchaser orders a title search. Or someone comes knocking on their door to put up a for sale sign insisting that they own this house lol. If someone buys the property from the fraudster and doesn’t get a title search done and title insurance (this is incredibly dumb, get a title search done if you ever buy real estate for this and many other reasons), then they may not find out they don’t even own it until they go to sell it. Or it could pass through multiple people’s/entity’s hands if nobody is getting a title search. They’ll all need to end up in court to get their money back. There are some registers who offer a sort of notification system for if your property gets transferred, but even still it just notifies you when the deed has been done (literally).

I think that creating a block chain could improve some aspects of real estate transfer, like needing to even do a title search, but I don’t 100% understand the nuances of how they work and would have questions about what sort of problems might arise if someone loses whatever key they use to access it or if they die or something and don’t leave a will with the key behind. Wouldn’t that create issues that would need a court to get involved to determine ownership?

If I’m interpreting your improvement correctly, that’s kind of how real estate property records already work (in my state in the US at least). As it stands now, a clerk at a county register of deeds office will record practically anything that you pay them to record. They do not interpret what is or isn’t a fraudulent deed, for example, because that would expose the clerk and the state to liability. If issues arise about ownership, that’s what the courts are for. Anyone can go down to the register of deeds’ office (or in some cases access the records online) and view the deeds because they’re public record. Other government entities, like the county assessor, will normally also make available a simple chain of title that shows you every deed/transfer of that property when you look it up by parcel number, address, owner name, etc. If a deed does wind up being determined to be fraudulent, normally the court order declaring it fraudulent and making a current ownership interpretation will also be recorded at the register’s office (those are called quiet title cases because the court is “quieting” all other parties who are alleged to have or claiming to have an interest in the property). So there’s both a public chain and a method of clearing up any inconsistencies in the chain.
