Japan's mtes Neural Networks and DTCO announced their partnership to promote the "CitiOS Project", combining structural health monitoring (SHM) and blockchain technology to monitor structural changes in infrastructures such as buildings, stations, railways, etc. CitiOS can significantly improve public safety for the areas that have suffered from earthquakes. Earthquakes has always been one of the biggest security issues facing Taiwan and Japan. The damage to infrastructures generated by earthquakes has often caused unacceptable casualties and an irreparable lost in property value. CitiOS will predict whether infrastructures changes in time and take necessary measures to overcome various defects. Moreover, with the aging of population in Japan, they can no longer rely entirely on manpower to manage urban infrastructures.
