Building a digital twin is more than combining the usage of real-time data and other sources. It enables also learning, reasoning, and dynamically recalibrating for improved decision making. Now, with the foreseen clusterization of the Internet, and tokenization of assets, national governments have a more crystal focus on what's going on with the creation of digital twins in their countries. Many large countries like for example China and the USA are trying to regulate and streamline these processes. When it comes to the EU, the landscape of PropTech and IoT solutions is a patchwork. The management of information about a real estate asset across its lifecycle phases, coupling the physical asset with its digital replica needs to be coordinated. But how does the market respond to these challenges and what are the best examples of emerging connectivity and data exchange platforms?
