1. blockchain is a kind of technology. "In the simplest and most popular way, blockchain technology is everyone bookkeeping, or distributed ledger."
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.

2. Different blockchain platforms or blockchain projects

white papers are different
white papers can generally be found on the official website of the platform
if not, they are unreliable
blockchain is the core supporting technology of the digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

3. The white paper points out that the China Telecom blockchain and digital economy Joint Laboratory has built a basic platform for blockchain innovation, and developed a SIM card based blockchain digital asset management system. The SIM card is the flow entrance of digital asset management, the digital asset trading platform, and the social ecology of real name digital assets
in terms of application scenarios, the white paper points out that 5g blockchain mobile phone has five application scenarios: digital identity authentication, financial application, supply chain traceability application, judicial application and express instry application

taking digital identity authentication as an example, blockchain technology provides a new technology route for decentralized digital identity, which can verify the identity of users through an ID. users do not need to remember traditional authentication marks such as user name and password. Any website can use ID as a way of user login, and can also be used as the identity provider of ID. it not only solves the problem, but also does not need to rely on the centralized website to confirm the digital identity
at the innovative scheme design level, China Telecom blockchain and digital economy Joint Laboratory proposes a blockchain mobile phone research scheme of "security platform, independent identity authentication, multi-level application" in combination with blockchain, 5g and other technologies, aiming at the key problems of "number change" fraud, telephone harassment, mobile phone loss, and unreliable information in traditional mobile phones
according to the public report, China Telecom also participated in the writing of the white paper on blockchain telecom instry application (version 1.0). In May of this year, the Third Plenary Session of the trusted blockchain promotion plan was held, and experts from China Mobile, China Telecom and China Unicom, the co leaders of the telecom application project team, on behalf of the project team, officially released the white paper on blockchain telecom instry application (version 1.0)
the white paper is the world's first white paper on the application of blockchain telecommunications instry, which was led by three major basic telecommunications enterprises and jointly written by more than 10 units, including Huawei, ZTE, fun chain technology and Huaqi communications. You can pay more attention to bitMom

4. You can understand blockchain as technology. Cryptocurrency is based on blockchain technology. The technology itself is reliable and can also be applied in other instries. But after the fire of cryptocurrency, a lot of people came in. If you want to invest in it, you have to recognize which projects are real and which are fraulent. Novices suggest to know more about the blockchain instry. Besides, there are risks in investment. Whether you lose money depends on you. Cryptography focuses on blockchain information

1. White paper is another name for an important document or report officially published by the government or parliament with a white cover. As an official document, it represents the position of the government. It emphasizes clear facts, clear position, standard writing, concise writing and no literary color

2. The white paper was originally named because the paper used in the cover and text of the book was white. Blue book is used to refer to some official documents, which usually represent the views of scholars or research teams

In the early days, blue book mainly refers to a publication of British Parliament. Because the cover is blue, so the name. It was first issued in 1681 and only sold in 1836. Its name is "British parliamentary instrument", which is a kind of diplomatic information and document submitted by the British government to the two houses of Parliament

The white paper may be a book or an article. Some official annual reports, materials or summaries of information were not originally published as white papers. Later, in order to show their authority and expand their influence, they were also renamed white papers

extended materials

the documents of various countries have their own common colors, and the cover is white, which is called white paper, such as China and the United States; Cover with blue, called blue book, such as the United Kingdom; Also useful red (such as Spain), yellow (such as France) or green (such as Italy), respectively, called red book, yellow book, green book. However, a country can use a variety of document cover colors. For example, Japan's defense annual report in white is called defense white paper, and its diplomatic annual report in blue is called diplomatic blue book
