Blockchain of Netcom
Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade
extended data :
1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

At present, blockchain is not only applied in the financial instry, but also in the following instries, such as banking, payment and cash transaction, network security, academic records and academia, election, network and Internet of things, prediction, right and so on. There are still many areas that need blockchain technology. It can be imagined that the Internet + we mentioned before will become a blockchain + situation in the future
from the demand side, finance, health care, notarization, communication, supply chain, domain name, voting and other fields are beginning to realize the importance of blockchain and try to connect technology with the real society
from the perspective of the investment side, the supply of investment funds for blockchain is graally rising, the investment enthusiasm of venture capital is also rising, and the investment density is increasing. The supply of funds at the supply side is expected to promote the further development of technology
from the perspective of market application, blockchain can become a market tool to help the society rece the cost of the platform and make the intermediary institutions become the past; Blockchain will promote the shift of the focus of the company's existing business model, which is expected to accelerate the development of the company
from the perspective of underlying technology, blockchain is expected to promote the transformation of data recording, data dissemination and data storage management; Blockchain itself is more like an open source protocol at the bottom of the Internet, which will touch or even completely replace the underlying basic protocol of the existing Internet in the near future
from the perspective of social structure, blockchain technology is expected to integrate law and economy and completely subvert the original social supervision mode; Organizational form will change because of it, and blockchain may eventually lead people to a distributed and autonomous society
Where should we start to learn blockchain
first of all, we need to have a comprehensive understanding of the source and cognition of blockchain from a macro perspective. Why do we need to do this? Because if we don't understand, we will have no voice. We don't know how to judge that the next outlet is blockchain. Even if people follow suit, we also need our own learning solution as support. So, what do we need to know? I have listed the contents, For your reference only, if you already know something about it, you can skip this step:
1), basic theory of blockchain
2), basic programming (computer software and hardware foundation, character set and character encoding, HTML5 + CSS3 and other front-end technologies, ECMAScript + BOM + DOM, jQuery, node.js, Ajax and express framework)
3) Go programming language and database operation
4), blockchain 1.0 programming - bitcoin
5), blockchain 2.0 - Ethereum
6), Star Cloud chain and EOS development practice
7), blockchain 3.0 - fabric of super ledger
to you who are still struggling in the tuyere of blockchain: there is a market when there is demand, and the society never lacks excellent technical talents, After a good understanding (you can refer to Qianfeng's blockchain video tutorial), you must be firm and accurate
it is the basic requirement for the development of network instry to adhere to the people-oriented and people-centered development idea with the support and participation of the people, any enterprise can achieve success; Any cause that can make people feel happy can be full of vitality. It's not hard to imagine what it would be like if a business just blindly strives for rapid development and ignores its main body. As a matter of fact, whether it is the cause of Internet information, or other scientific and technological undertakings, financial undertakings and so on, it is ultimately to serve the people and realize the interests of the masses. Practice is the only standard to test the truth. It can be said that the cause of the past has flourished in this way. Only by providing the common people with usable, affordable and well used information services and creating a healthy and good cyberspace for the vast number of Internet users can we meet the needs of the people and realize the better and faster development of the Internet information cause. Think about those undertakings that only care about personal interests, ignore the long-term development of society, and can benefit mankind. At the beginning, they may be able to make small gains and be complacent, but they will try their best to catch fish and eventually fail
"water can carry a boat, but it can also overturn it." It can be seen that the development of Internet information instry is based on serving the people. The development of the Internet only people-oriented, think of the masses, do what the masses do, in order to go further and further, the foundation will last forever. Of course, compared with the expectations and needs of the people, there are still many gaps in the procts and services provided by our network. It is necessary to make a breakthrough in core technology as soon as possible, speed up the popularization of information technology, so as to rece the service cost. At the same time, it is also necessary to strengthen the governance of cyberspace to provide a clean cyberspace for the majority of Internet users. It is necessary to build a network information security system, and fully perceive the network security situation, Make the Internet really become a tool to benefit the people, and gather the great power of the development of Netcom
It has been more than several years since the first World Internet Conference. The thoughts and marks left by the world's Internet figures in Wuzhen have become valuable experience and wealth in promoting the development of the Internet, and also bred great unity and cooperation in the Internet instry. From "interconnection, sharing and co governance" to "innovation driven, benefiting mankind", what has changed is the new trend of the times of the Internet information instry, and what remains unchanged is the original intention of building a community of shared destiny in cyberspace
now is a digital era. Focusing on digital economy not only caters to and promotes informatization, but also proces endogenous force to promote economic transformation and upgrading. The digital economy of our country has developed rapidly in recent years. Data show that in 2016, the scale of China's digital economy reached 22.4 trillion yuan, accounting for 30.1% of GDP, and the transaction volume of e-commerce reached 26 trillion yuan. The average annual growth rate of online retail is 30%, and the number of Internet users in China has reached 750 million. E-commerce, big data, cloud computing, artificial intelligence, sharing economy and other new market words are familiar in China. There are also micro stores, mobile payment, bike sharing and digital poverty alleviation that are more suitable for people's life. These are also brilliant colors in the development of China's network information instry
