Last transaction in this case will be your public key transferring the land to my public key. So they know that I own the land now.




But I read somewhere every one in the system has to agree ani undi but I will read more.

Everyone has a copy of the ledger. If you change something on the ledger at your end, it is not in sync with the established version of truth that everyone shares. So the change is rejected at the protocol level.





missed this point bro but as an example naa land meeru konte dani ki 3rd party kuda oppukovali kada? how will rest know this transaction really happened or its a fake?

This is very tough to do ani gatti abhiprayam due to inherited land issue in India (I dont know about other countries)




Completely agree. There are other dimensions as well. Was talking an oil giant the other day - who is into offshore and onshore drilling for oil. Apparently land ownership has a vertical flavor also to it. (For instance, you own only up to 10 feet from the gound level. After that, it is owned by someone else till 20 feet. Then someone else too.) So if someone needs to drill for oil, they need to enter into an agreement with all those people/organizations as well. So land records have to contain not just the surface level data but the vertical ownership as well.

in public domain like registration dept, if we encrypt something we need a way to decrypt also like for encumbrance certificate, so inka ela trust chestam system ni??




You can't trust a copy of a document that resides on the blockchain. The party that needs this document has to get it directly from the blockchain. Since a hash of the document is recorded when a document is uploaded, the person who needs to get the document - can download the document - create a hash and compare the hash with the hash recorded on the distributed ledger. Even if a single character changes, the hash will be different. So you are assured that you are looking at the right version of the certificate in this case.

Looks like the validity of initial digitization process is the key for this to be successful (in this use case)




This is very tough to do ani gatti abhiprayam due to inherited land issue in India (I dont know about other countries)

naa experience atleast 70-80% properties were never sold in a generation they are passed on one generation with out proper Will or partition documents

in those cases lot of issues unnayi to decide who owns the property, govt records suggests one person but as per law there would be multiple.

Records (sale deeds) lekunda unna lands konni lakshala acres undi untayi, vatillo govt records lo intiki peddakoduku or evaru lancham ichado vadi peru untundi

abbo chaa racha undi but has to solve this at somepoint

Blockchain is not a new technology. You can do the same using existing tech too. It is just one way of doing it.

Everyone has a copy of the ledger. If you change something on the ledger at your end, it is not in sync with the established version of truth that everyone shares. So the change is rejected at the protocol level.

That's why it is important to note that blockchain makes sense only in a cross-org/trust boundary situation.

Tadi_mattayya:

Layman terms lo pls describe the usecase for Blockchain in India Property Registration/sales.




Use case remains the same as the actual process of doing it in the real world manually. The steps will be automated through smart contracts and the data is immutable (can't be modified). So tracking the ownership of a plot, for instance, becomes easy and you can avoid multiple registrations of the same piece of land.

Just thinking off my hat - here are the steps

1. Definition of a digital token that pertains to a piece of land in the real world.
2. Any transactions on that digital token persisted in a distributed ledger - with a hash of the supporting documentation as well. Each party has a digital identity on the chain. So the person who is selling the land has to mention the person who is buying it.
3. Value of the land is recorded as well. A smart contract can compute the tax overheads and create a transaction to issue a tax notice to the owner (just an example)

What prevents you from defining two different digital tokens for the same piece of land? As long as the land records are digitized by the government, they have some sort of an id - The id on the blockchain refers to/pertains to that id. In an ideal world, the land records themselves are on a distributed ledger. You define the various parameters that can uniquely and unambiguously identify a piece of land. (For instance, GPS coordinates of all corners of the land - and probably more such inputs) - Then convert the land that is being traded into a digital token using those parameters. Once it is digitized, system will not allow you to create a duplicate entry for the same land.

Use that digital token to record transactions on blockchain/DL. Eppudanna to prove ownership or history of the land - you just have to track all transactions for the digital token. Getting an encumbrance certificate for instance is no longer necessary.

Of course, this is purely off my hat - chaalaa complications untaayi and the system should be designed in a proper manner with lots of workshops, whiteboarding, JADs etc.

Hope it helps.

Gandhiguevara:

Mari mareechudu yenti Blockchain is database lady_abba antaadu




Blockchain is a way of storing data. It is an architectural pattern. Anthe. You can do that with existing technologies. In fact avannee existing technologies yeh - just stitched together in a particular pattern so as to have "trust" as an inherent characteristic of the system.

Can the same be done without the name "blockchain"?

Yes

Is Blockchain the same as Distributed Ledger?

No.

Is Blockchain for everything?

No. 90% of it is just hype. 10% realistic use cases now.

Can it change the world?

Yes. Provided you cut through the hype and use it specifically in places where it makes sense

Where does it make sense?

--> Is your business process crossing organizational trust boundaries?
--> Do multiple orgs/departments that don't necessarily trust each other completely - need to work on the same set of data? (Not just accessing it but adding to it as well)
--> Does your process include mundane and manual verification steps just to bring trust into the picture?
--> Are there any intermediaries that control your single source of truth?

These are the four basic questions that you need to answer before even considering a business process re-engineering task that lends to a down-the-line implementation of a technology solution - where a distributed ledger may play an important role.

Is Blockchain by itself a game changer?

No. Blockchain is generally one part of the picture. You need secure off-chain storage, off-chain processing, integration with OLTPs, hooks to analyze the data and run ML models on it. If you look at a blockchain use case - tech architecture, 90% of it is not blockchain related.

Proof of work? Mathematical problems?

One way of ensuring trust is in the protocol level. Anthe. Enterprise use lo konni features of Blockchain - light teesukuntaaru - For instance, trust being implicit - Since enterprise consortiums lo there are no untrusted actors or nodes kaabatti you don't have to use proof of work and the processing overhead that comes with it. So you can change to Proof of Authority for instance if you are using Ethereum. Alaa konni light teesukunte you will get to around 2000 transactions per second - which is exactly the number of transactions cleared by Visa or Mastercard - so they can look at this pattern with interest.

Had a no-nonsense chat with Ajay Bhalla (Mastercard) last week in Oxford University and while he sees great potential in blockchain, he feels the same way about the current hype. IN his own words - "A lot of the talk today is spiritual. We have to wait till the conversation comes to a practically plausible level."

So, Blockchain isn't good?

I didn't say that. I believe that Blockchain is a gamechanger provided it is properly conceptualized and architected - and works with other great innovations of the ML age.

I am working with NITI Aayog right now to define what IndiaChain should look like (India wide blockchain ledger that citizens, government, public and private bodies can interact with). Lots of challenges and moving parts. We will get there. But at the moment, to quote Ajay Bhalla again - it is borderline spiritual stupidity and most folks have no clue what blockchain is all about - and think cryptocurrency is what it is all about.
This world appearance is a confusion: even as the blueness of the sky is an optical illusion. I think it is better not to let the mind dwell on it, but to ignore it.
