- #15 Land records data need to be accurately stored in the blockchain. The existing history of transactions on a piece of land first needs to be inserted into the blockchain after approval by Revenue functionaries in the State. The approved data will be digitally signed and stored. This will be a starting point for any mutation. The certificates issued by the Revenue Department will be stored in the blockchain and can be used by the other agencies like the bank for any of the verification process during a transaction on the land parcel / farmer. The transactions related to change of ownership through sale, loan, mortgage, release of mortgage, crop updation is initiated by other departments. During the initiation of above mentioned transactions, the verification of the details need to be done using the blockchain data. After the approval of transaction in the respective database such as completion of deed registration / approval of loan by the bank, the transaction details should be stored in the blockchain. Specifically, the registration department will fetch details w.r.t a survey number from the blockchain and ensure that the ownership of the land parcel indeed rests with the prospective seller before initiating a sale. After obtaining the signature of the purchaser and seller in the sale deed, the scanned document should be moved in to Blockchain Network to create a block. Once the block is created it cannot be edited or tampered. Likewise the chain of block is created every time the property title is changed from one person to another.
