X-Block is a global public chain built on the Fog computing framework, which aims at creating a user-friendly, convenient and open light Eco-Blockchain. It has created a public chain that lowers the participation threshold of Blockchain Technology, creating a network that allows all types of devices to join and contribute their computing resources. In order to realize the goal of Fog computing, the overhead of consensus must be reduced to a minimum, while maintaining speed and efficiency. This allows X-Block to have a rapid allocation of resources across the network.
