Real estate is a terrible example of where to use a blockchain. Someone gains access to your private key and you just... don't own your house anymore? There's not really a recourse here since it's controlled by the distributed system. On the other hand, the government which is entrusted with the authority to enforce laws can hold onto the this information in a more secure way than the average person. And if something does happen they have the ability to fix problems without issue. I read all these stories online about wallets getting compromised and contents stolen with very little recourse and am confused why I would want the largest purchase that I will ever make in my life tied up in that. Doubly so because that purchase is explicitly tied into the central authority of your government. It's not like cryptocurrency where it can exist externally to the current legal system. Real estate MUST be tied to government in some way.
Your point about how building a secure, central database will have so many technical hurdles to overcome is... odd. I mean, sure it's tough to make a secure database. Your answer is that some blockchain framework has certain security characteristics while ignoring that literally every secure data store that currently exists is running on a central database and just fine at that. Like, what do you think that your bank is using at this very moment? There are multiple companies with well-audited solutions selling and running secure databases RIGHT NOW. You just hand wave away the ability to make secure databases while ignoring that they already exist while expecting us to buy into the promises of some new, unproven framework like Hyperledger. The only thing that blockchain adds is immutability, which is something that I think would be a poor idea anyway.
Lastly, blockchains only work by having users with a financial stake and incentive. With proof-of-work you're staking the cost of the electricity you're spending, with proof-of-stake the crypto you're staking. The point is, they have this whole weird financial structure to keep people running this distributed ledger. How would that even work for real estate? Do you want people with perverse financial incentives muddling with the system that controls your ownership OF YOUR HOUSE? Or the government which is empowered by the people to serve them. And if it fails those leaders face expulsion? I know where my answer is.
I just want to hammer this point home one more time. This is a false comparison. You do not have to build these features yourself. Like, have you heard of this tiny company called "Oracle"? Or maybe this really obscure one "Microsoft"? They both make exactly this product.
Depends on a) what keys you have, b) who even gets to make mutations and c) if the system has provisions for "edit" transactions (which don't change history but say – to put it very simplistically – that eg. "previous transaction x is invalid"). Also it's unclear why you think this is different from a database password being stolen.
I wasn't saying to throw away existing systems or that banks aren't running secure databases. Jesus christ you seem more intent in just being indignant about me daring to have a differing view about something than actually reading what I said.
You also clearly don't understand what Proof of Authority means and didn't bother to read my explanation, since PoW / PoS are completely different consensus mechanisms and the problems with them don't apply to PoA systems.
Remind me which Oracle or Microsoft database solution gives you signed state mutations, a guaranteed immutable and tamper proof history.
Honestly your whole argument relies on you not bothering to read what I wrote and then answering with sarcastic comments based on what you assumed was said. I know you don't agree with me, but try not to act like a twat just because you don't.
Under the current system you don't even have a private key. In some countries it's fairly common for someone to lose their home because someone bribed the official to change the title records.
I think that key management is blockchain's Achilles Heel, but there are some interesting potential solutions
If the state, with its monopoly on force, says that you don't own land, what difference does it make if it's a piece of paper, a record in a traditional relational database, or a transaction on the blockchain?
Title ownership of a piece of land is only as good as the enforcement mechanism of that title mechanism. Changing from recorded paper deeds to PDFs in a centralized database made sense (and was backwards compatible). Changing from PDFs in a centralized database to a blockchain doesn't actually change the enforcement mechanism, and makes it less efficient. So what's the point?
Obviously if the state doesn't enforce the titles they're useless. Sure if the president of a corrupt country decided he wants your house he's gonna get it. But a DLT would prevent lower level corruption that relies on the benefit of the doubt.
If a corrupt official uses their access to change the PDF title of your house to be in his name, he could take that to court to take your house from you. A ledger would prevent that change from happening, or at least leave a permanent record of the change
Yes. That's why most western land ownership systems moved to written ledgers in continuous, sequential books since, like, the slow collapse of feudalism 400-600 years ago. Let anyone add to the record but store those records in a way that they can't be tampered with or removed after the fact, and let basically the entirety of the county's land ownership records be tied up in one ledger that all land owners have an interest in properly preserving integrity.
Basically, blockchain doesn't actually help any more than simple/regular digitization does. Which already happened in most places 25-50 years ago.
A trust less system also can aid in stymieing wire fraud in real estate transactions which is shockingly common. Today, someone doesn't even have to have your private key to pretend to be you and steal your escrow funds - just a spoof email, good timing, and a paralegal that makes a mistake
