Reveal the blockchain: what does a "super ledger" bring?

Despite the specialized vocabulary, the blockchain is indeed "fire", and even the ordinary people's WeChat circle of friends has been interpreted as refresh.

In the age of the Internet, every new thing has its imagination. Understanding what the blockchain is is the premise of all expectations, questions and discussions.

A "super ledger" for everyone

"Use block chain data structure to validate and store data" "secure data transmission and access by cryptography"... A professional interpretation of the entry is the block chain shrouded in mystery.

For chain blocks, some people think that is a new set of technologies algorithm, some people think that is a kind of new mechanism, also some people think that is a new concept, and no matter how, block chain indeed present beyond the traditional Internet some new characteristics.

-- bookkeeping. On the Internet, a large amount of data is recorded every day. In the current technology mode, the data is recorded and stored by a centralized platform. In the block chain mode, a block is equivalent to an account page, and the block chain is equivalent to a large ledger that is connected to the end, and each person has an opportunity to participate in the accounting process.

-- hard to tamper with. Interlocking block chain blocks, each block will correspond to a long list of function password, if you modify a block, then the subsequent block content no longer match, lead to information tamper with the invalid, it makes the integrity and authenticity of the information on the Internet. Some in the industry have called the difficulty of tampering with information on the block chain "finding a grain of sand in all the sand on earth".

-- decentralization. Compared to the traditional way, the blockchain can realize the automatic operation of a system without the management of the central organization. "The two foreign bodies can achieve the direct and efficient transaction of point to point without relying on third-party intermediaries to achieve low cost and quick trust." Yu jiining, director of the industrial economics institute, information center of the ministry of industry and information technology.

For example, online shopping products now need a third-party payment platform in the payment process, and under the application of blockchain, the seller can realize the direct transaction under the trust mechanism.

A "middleware" to deal with pain points

When it comes to the blockchain, many people think of bitcoin, or even confuse the blockchain with bitcoin. In fact, blockchain is the underlying technology of bitcoin, and bitcoin is the practical application of blockchain. The blockchain can be applied in many areas.

Solving the pain points and difficulties is the internal driving force of many new technologies in the Internet age. The block chain has the characteristics of transparent and efficient, safe and stable, reducing the intermediary and credit cost, so that it has the prospect of application in many fields.

One of them is the supply chain management, such as wal-mart and IBM, a experiment is carried out using block chain of food from the shop back to the farm, can from the traditional method to improve to a few seconds, a few days and ensure the authenticity of information.

Such as in the field of trade both sides need to trust international trade, at the end of last year, China's sinochem company for crude oil imports from the Middle East to China business, successfully completed the first single block chain oil imports trading pilot, optimize trade financing costs 20% to 30%.

In the field of public welfare charity, the process information such as donation project, fund flow, and recipient feedback can be stored in the block chain and more open and transparent for supervision. In the field of digital copyright protection, the authenticity and uniqueness of ownership can be guaranteed by blockchain. Block chain has the difficult to tamper character, also let it have broad market in the field of authentication and notarization...

Zhang Ye, director of the China securities regulatory commission information center that is encrypted with block chain, trust, point to point, difficult to tamper with the "middleware" for the label, such as link up the application of the Internet and the actual scene, a good supplement of the current Internet some deficiencies, this can make certain industries have had no effect, but block chain does not apply to all scenarios.

The birth of new things is often full of discussion. Some people believe that the current application of blockchain is only the tip of the iceberg of infinite possibilities. Others believe that there is still a lot of uncertainty about the development of the block chain in the future, and its application field may not be so broad.

A "new world" of multi-party layout

Every new thing is like a new continent, with opportunities. Although the blockchain is still in its infancy, both the international and domestic markets, governments and markets have been making frequent moves.

The European commission initiated a new mechanism to promote the development of block chain technology; The U.S. house of representatives has held hearings on the block chain. The international standardization organization, the international telecommunication union, the world wide web consortium, etc., have launched the standardization of blockchain. Multinational companies such as the shipping giant maersk, the retail giant wal-mart and the tech giant Intel are also laying out blockchains.

Domestically, the state council in 2016 issued by the "" much starker choices-and graver consequences-in" national informatization planning "will block chain technology as a strategic technology, based on the number of block chain driven by the central bank bills trading platform has been tested successfully, the ministry will lead the national chain block and the distributed technology standardization technical committee of charge to an account to carry out the research.

More and more places are getting involved. Hebei xiong 'an new area explores the use of block chain and other technologies to establish a scientific and effective integrated life cycle management mechanism for housing lease; Chongqing, Qingdao and other places began to build the block chain industry base and incubation platform from the perspective of industrial planning.

Investment in the future has always been a consistent feature of large domestic Internet companies. In terms of block chain, tencent has explored the supply chain finance, digital asset protection and other fields. Alibaba and jd.com focus on the transparent supply chain system to crack down on fake and inferior products...

"Blockchain is just a technology, and it is not a mystery in itself. It can only be reflected in the real estate scene. The important factor that determines the future of blockchain is the degree of integration with the real economy to see how it can improve the industrial integrity development environment and solve problems for the real economy.
