Blockchain in Internet of Things

Block chain technology will not only deeply affects and changes the financial industry, but also plays a revolutionary role in the field of Internet of things. It is a kind of technology that connected by sensor, controller and machine equipment through the network, realizing the aim of intelligent management and control for machine equipment through things connection. Internet technology connects all the computers around the world together, realizing the remote communication between people, promoting the great progress of human civilization.

As anonymous decentralized peer-to-peer remote sensing technology, Blockchain has become a public ledger for a large number of equipment, and they no longer need to have a centralized routing between them. Without the verification of central control system ,the equipment will be able to realize the anonymous transmission between each other, and manage software update, errors, or energy management.

Block chain technology can provide Internet way of point to point for data transmission, the entire Internet solution does not require the large data center for data synchronization control and management, including data acquisition, sends instructions and software update, all these operation can be transmitted through Blockchain network. The problems of block chain technology in Internet of things are mainly for the three aspects:

• Architecture for distributed point-to-point data transmission and storage;
• The data encryption protection and authentication mechanisms under the distributed environment；
• Fees settlement and payment in a convenient and reliable way.
