Telecommunications company Orange has partnered with Polish blockchain company Smartkey to improve access controls to buildings and city services across Poland. Several city governments already use Orange’s IoT platform to remotely manage city services such as street lighting control. The partnership builds upon this technology by integrating Smartkey’s blockchain solution, which ensures that the data from the IoT sensors cannot be falsified after its creation. When combined, the two platforms will enable authorized city residents to gain quicker access to specific buildings and city and commercial services. Eighty cities will participate in the initial rollout.
