Maybe the strongest case for where block-chain could be beneficial is origin and transfer of ownership of the assets, and property registry is mostly a good case. There have been many pilot studies and concept are made.
If land transactions were handled with block-chain, it could be record the whole transaction history of a land or property, which would be enhance the effectiveness of the transactions processing and fight with corruption by dividing the maintenance of records to all the participant.
Via smart contracts, property exchange could be also monitor specific instructions coded as part of transaction to be fulfilled automatically once agreed standards have been met, further increasing the efficiency of the exchange process.
As register, the openness of the block-chain isn’t an obstruction for the property registry. It’s acceptable for the participants to see who keeps, retails, and divides property. Also, the verifiability feature can help to enhance transparency where needed.
A property registry block-chain would have to start by tokenizing property – this is, creating a symbol of each sector of property as a legally-equivalent digital property or assets, stored on the block-chain. That would be followed by the certifying the existing owners had the ownership of the appropriate tokens assigned to them.
