There are a lot of potential applications for blockchain in the real estate industry. For example, blockchain could be used to make land title registration more efficient and secure or to streamline the process of buying and selling property.
I think one of the most promising applications for blockchain in real estate is in the area of property rental and management. Blockchain could be used to create a decentralized database of rental properties, which would make it easier for tenants to find housing, and would help landlords manage their rentals more efficiently.
