> Blockchain automagically makes selling of something impossible? This issue here wasn't about selling something - unfortunately in India when it comes to land

> Blockchain automagically makes selling of something impossible? This issue here wasn't about selling something - unfortunately in India when it comes to land, possession is nine tenths of the law. It doesn't matter if you're the true legal owner if somebody else claims physical possession and has a vaguely genuine looking piece of paper. Proving or disproving the veracity of that piece of paper takes many many years, and in this aspect India is different from many other places in the world. > How is this a) different from my examples It's not very different from your example, though my anecdote is meant to demonstrate some of the real life issues meant to be addressed. I'm not convinced that a blockchain is the correct solution, but I can understand the motivation. > You don't need "modification". All you need is the next entry: "the rightful owner of X is now Y". How is blockchain going to prevent anyone from doing this? Unless I'm misunderstanding how blockchains work, how can that next entry be created without being signed by my private key (and my consent)? I have no idea if any concrete suggestions have been made around the architecture of land record blockchains, but it could presumably be something like a multisignature wallet: each transaction has to necessarily be signed by the seller, buyer, & government authority. Of course, like I stated in my original comment, I'm not convinced that blockchain is the correct solution here, or how certain issues could be realistically resolved.

  One of my own personal misgivings around the blockchain for government services is the management of private keys. However, I don't see this as a conversation killer, and is something that could probably be resolved. Issues around concepts like Power of Attorney, co-ownership, & time limited ownership can be resolved by something like Multisignature wallets. Court orders changing ownership without the owner's consent could also be resolved the same way: the Sessions Court is a non-required signatory on all multisignature land registry wallets, with the District Magistrate & Sessions Judge keys sufficient to sign transactions. > It even breaks for my example of "Ahmet illegaly obtained ownership in the very beginning". I don't think any sort of land registry record reform can hope to resolve issues like this. This problem isn't resolved by digitizing records to a regular database either. In India, the sort of issues my family & others have faced around land ownership claims is that the original records are largely on paper, nearly impossible to verify with the district administration, and all most people have is a faded paper receipt decades old. This is the weak point exploited by bad actors. I'll offer a personal anecdote this time. Some years ago we tried to transfer the ownership of our home to the name of our mother (it was registered in the name of my late father). The only paperwork we had received decades ago was a paper receipt. We hired a lawyer, appeared before the District Magistrate, gave affidavits, and the process chugged along for years. When it came time to verify the details of the registration, the relevant pages from the registry were 'missing'. The fact that we had paperwork proving ownership meant nothing since the master records were unavailable. We filed another petition which took even more years, till our lawyer suggested that a bribe in the right hands in the district records office might surface the original missing pages. Sure enough, a few months later the missing pages were "rediscovered". Then there were inspection agents who came to remind us that everybody along the greasy pole had to be sufficiently lubricated. The entire process took 10 years, a great deal of anguish for my elderly mother, and quite some money. This was in a large city, and the situation is worse in more rural areas. Does a blockchain based land registry resolve every single one of these concerns? No, but neither would a database. A database would resolve many, but not all of the problems I faced. Similarly, a blockchain might resolve different issues, and likely raise new concerns. From my perspective, given how bad actors at the district administration operate, I'd be wary of a database they had control over. Sure, there are probably ways to address those concerns, but I can also see why people see the blockchain as a possible solution.

    The problem with blockchain is that it's just a distributed append-only log. There's really nothing else inherent in it. There are very few, if any, applications for it. However, too many conversations around it attribute magical properties to it. And any solutions built on top of it can, and have been, built more efficiently using almost literally anything else. Well, paper records are less efficient :) And as far as trusting databases goes, in the end you need government to accept whatever records there are. And nothing can help there. And even in blockchain world hard forks and re-writing of history happen even without any governments.
