Project Description

The Land Registry has the legal task of managing registrations and providing information. Important examples of this are the registrations of real estate, topography, ships, and aircraft. In addition to information about its own registrations, the Land Registry also provides information from other parties’ registrations. The Land Registry stands for reliable data in the field of real estate and geography, thus promoting legal certainty in the real estate market. Optimal data quality is of crucial importance. The Land Registry, in collaboration with Xurux, looked into the possible role of blockchain technology in improving the quality and reliability of this data.

Imagine you need information to apply for a building permit for your home. This application is based on, among other things, the cadastral data of your home. You check this information online and get to work on your application. Your application is submitted and rejected because the cadastral data turns out to be incorrect. This brings forth a question: where does the data come from and where does it go wrong? When inquiring at the Land Registry, it is unclear where the data comes from. It most likely does not come directly from the Land Registry. But, just like many other people, this is your assumption. You assume that there is only one source for this type of data. But that is not the case, therefore you place blame on the Land Registry.

The Land Registry and Xurux have jointly carried out a test that makes the origin of data transparent and the source demonstrable. This increases the reliability of the data and the Land Registry. By storing the information that you get from the Land Registry encrypted on a blockchain, you can prove that the information provided does indeed come from the Land Registry. It works like this: by comparing the (cryptographic) key of the provided file with the (cryptographic) key that the land register has stored on the blockchain, it is immediately clear whether the keys are identical. If this is not the case, the data does not come from the Land Registry. In this way, as an applicant for a permit, you get more certainty about the reliability of the data and the application. The Land Registry can thus protect its reputation, better guarantee the quality of the data, and be of better service to their applicants.

There are many more advantages to this solution. The issuing authority can immediately check whether the data is correct and does not have to request and verify it again themselves. They can do the simple comparison of keys and directly know the source of the data. This saves time and labour, making the application process faster. This is in line with the objectives of the Land Registry: ensuring optimal data quality, timely delivery of products, and knowledge of the state of the art (in this case blockchain technology).
