Shared bikes can be seen everywhere in the streets, payment codes at the door of every store, and the emergence of unmanned supermarkets has become a trend. Now people have exerted the convenience of the mobile Internet era to the extreme, and we can almost “do anything” with only a smart phone. Since the first smartphone hit the market in early 2007, we have entered the era of the mobile Internet. After more than a decade of spurt, mobile Internet technology is maturing. But in this Internet age of rapid technological change, mobile Internet seems to be no new technology. After the mobile Internet, who will seize the next wave?




Satoshi Nakamoto launched bitcoin client in 2009. Bitcoin is a decentralized currency system he developed based on his reflections on the 2008 financial crisis. Bitcoin was launched with a new technology called blockchain. Despite the block chain technology and currency, is not able to quickly gain to the enthusiasm of people, but in the age of the Internet in recent years, more and more serious crisis of confidence in block chain technology with its decentralized, anonymity and consensus mechanism has attracted the attention of people, block the application of value chain begins to be cognitive and mining.

In recent years, blockchain technology has still become a hot topic. As blockchain technology has stepped out of the laboratory stage, its application practice in reality has been greatly accelerated, and blockchain technology has been applied in more and more business scenarios and business fields in an increasingly diversified way.

If we explore this new technology in depth, it is not difficult to find that blockchain is a system with characteristics of distribution, self-trust, openness and transparency, immutable, collective maintenance and privacy protection. Distributed, the rights and obligations between any nodes in the whole system are equal, distributed accounting, dissemination and storage; Self-trust, using a set of open and transparent encryption algorithm so that the whole system can automatically and safely exchange data in a self-trust environment; Open and transparent. Blockchain data is open and transparent to all; Immutable, through the whole network broadcast, each participating node has a complete database backup, only change more than half of the database can change the data; Collective maintenance. Data blocks in the system are jointly maintained by all nodes. The nodes are open source and anyone can participate. Privacy protection, there is no need to disclose identity between nodes, the privacy of each node is protected

.

Several technical characteristics of block chain make block chain technology firmly grasp the next wind in the Internet era when trust mechanism almost collapses. Blockchain technology has also achieved increasingly mature development with the upsurge of people’s attention. At the present stage, the implementation of blockchain technology in the traditional field is not very ideal, and the further development of blockchain needs more support from governments and organizations.
