IBM recently unveiled at “Think 2018” in Las Vegas a micro-computer that measures only 1 x 1 mm (the size of this [_] square sign); it is solar-powered and has optical communication via LED.
The tiny computer can be embedded into goods to provide a blockchain entry at each shipping stage and allow tracking the shipment from origin to destination.
The 1 x 1 mm micro-computer is a complete system-on-a-chip and has a crypto-anchor: A unique digital fingerprint that makes the blockchain entry tamper-proof.
The urbanization of the world combined with the overall growth of world’s population will lead almost 5,000 million people to live in cities of less than 500,000 residents by 2030, but also in mega-cities (10 million inhabitants or more) and large cities (between 5 and 10 million dwellers). In 1950 the urban population was 746 million and grew up to 3,900 million in 2014. Urbanization is growing exponential, as shown in the following chart based on figures published by the UN.
Urban development has become a challenge to meet the needs for housing, transportation, energy, and employment in the 21st century, according to John Wilmoth, Director of UN DESA’s Population Division.
Small cities are growing fast and if well managed, they will offer opportunities for economic development, and access to health services and education for a large part of the population.
Car traffic and transit systems will improve by implementing #SmartCities Technologies.
