At the moment there is hardly any technology that everyone is talking about as much as the blockchain, and yet, on the one hand, knowledge can often be expanded. Specific applications are as rare as the word is often used. So the term and apparently everything that has to do with it finally reached the real estate industry. But why should we "real estate people" now also deal with the blockchain? As Marc and Michael explain: Because it is a multi-purpose tool, that can heighten the efficiancy, lower the costs and therefore has the potential to substantially influence and change the real estate industry.
