1. First of all, we can take a look at the official website explanation of blockchain technology. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
as we all know, blockchain technology is an independent underlying architecture from bitcoin system. From the perspective of architecture model, it is a set of distributed ledger, which is naturally used for bookkeeping
in the blockchain technology, if you want to generate accounting records, you need to have the transaction and flow of funds. Therefore, in the initial blockchain technology, the cryptocurrency corresponding to the main network is used as circulation goods, and the circulation transaction records of cryptocurrency between the accounts of the main network of the blockchain will be recorded on the main network
different from other transaction record databases, transaction records on the main network of blockchain technology will be recorded on all block nodes (i.e. all data blocks) in the main network, which is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to store all records, Every block on the chain has the transaction data of the whole chain, that is to say, every data block is the center
another feature of blockchain technology is that it can't be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can change the record. Even if you change it, all other data blocks will also record real data, and each group of data can be traced back to the first time
because of these characteristics of blockchain technology, after the advent of bitcoin, blockchain has also attracted a lot of attention, and many people also began to want to use blockchain technology to make a centerless, traceable and unchangeable data, so as to ensure the credibility of the data
however, blockchain technology also faces many problems, such as single application scenario, non modifiable original error data, non recoverable currency stolen by hackers, etc.

2.
From the perspective of technology and architecture, I will tell you my understanding of blockchain in common language
what is blockchain? In a word, blockchain is a storage system. To be more specific, blockchain is a distributed storage system without an administrator and each node has all the data
What are the common storage systems like
first, how to ensure high availability
the common storage system usually uses "rendancy" to solve the problem of high availability. As shown in the figure above, if the data can be copied into several copies and rendant to multiple places, high availability can be guaranteed. The data in one place is hung, and there is data in other places. For example, the master-slave cluster of MySQL is the same principle, and the raid of disk is also the same principle
two points need to be emphasized in this place are: data rendancy often leads to consistency problems
1. For example, in the master-slave cluster of MySQL, there is actually a delay in reading and writing, which means there is a inconsistency in reading and writing in a short period of time. This is a side effect of data rendancy
The second point is that data rendancy often reces the efficiency of writing, because data synchronization also consumes resources. If you add two slave libraries, the write efficiency will be affected. The common storage system is to use rendancy to ensure the high availability of dataso the second question, ordinary storage system, can write more
the answer is yes, for example, take this graph as an example:
in fact, MySQL can do a master-slave synchronization of al masters, master-slave synchronization of al masters, two nodes can be written at the same time. If you want to do a multi room multi live data center, in fact, multi room multi live data synchronization. What we should emphasize here is that multi-point writing often leads to the consistency problem of writing conflicts. Take MySQL as an example, suppose that the attribute of a table is self incrementing ID, then the data in the database is 1234 now. If one of the nodes writes and inserts a piece of data, it may become 5, and then these 5 pieces of data are synchronized to another master node, Before synchronization, if another write node inserts a piece of data, a piece of data with self incrementing ID of 5 will be generated. Then, after the generation, synchronize to another node, and the synchronized data will conflict with the two local 5's after it arrives, which will lead to synchronization failure and write consistency conflict. This problem will occur in the case of multi-point writing
how to ensure consistency in multi-point writing

3. No way. Blockchain still has a long way to go. In 2018, any company will only stay on the goal or structure. As for practicality, without 20 years, you don't have to think about it. If you can't stay on the real technology, you can't popularize it. Without hardware and the use of the masses, blockchain is just hype. When the issuers finish collecting the wool, there are still followers who want to cry, In fact, I think AI and the Internet of things have made great achievements. The Internet of things began to be used ten years ago. At that time, the Internet of things was further than the blockchain now, and it has not yet been popularized. AI started its research and development 30 years ago, but it has just started to be used now, and the good ones are apple and Microsoft. As for other companies, At best, it's just making enhanced 3D glasses
4. After all, this year's blockchain fire, so these big guys are sure to participate. In terms of anti-counterfeiting traceability, the use of blockchain technology can be very good. Compared with our current anti-counterfeiting technology, blockchain technology is more suitable. Do anti-counterfeiting traceability is not much, such as "DITO traceability chain" is.
5. 1、 Decentralization:
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity:
unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

6. Concentric mutual aid, founded by blockchain start-up company Abbott, is a network mutual aid platform applying blockchain technology, and also the first real blockchain landing application in China. Concentric mutual aid combines open source code with practical application, realizing the deep matching between blockchain technology and network mutual aid
e to the technical characteristics of blockchain, concentric mutual aid has three characteristics: first, all capital flows are open and transparent, which can not be forged or tampered with, and each user can exercise the right of supervision. Secondly, the transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention. Finally, each user's personal sensitive information will be highly encrypted, and no one else can access it. Based on the above three points, the problems existing in the traditional network mutual aid mode have been solved one by one. In addition, in order to ensure the authenticity of the payment, the new "jury" system has been established in the supervision mechanism, which forms a professional identification system with lawyers, doctors, judges, police and other public officials, so as to ensure the authenticity and reliability of each payment, and completely eliminate the most critical defects of traditional network mutual assistance.

8. First, you need to know what chips are
a chip is definitely not a technical indicator, but refers to who controls most of the circulating capital stock of a stock, and who plans to compete with these stocks next, that is, chips
then, to put it simply, the chips are in the hands of the company faction or the market faction, so the stock price is easy to rise but hard to fall. But if it is in the hands of retail investors, it is easy to fall but difficult to rise
finally, it is necessary to subdivide the characteristics of chips held by different main players. For example, the holding of foreign funds by national team legal institutions will be a medium and long-term trend, while hot money will be mainly short-term speculation
I don't think you should feel much. Let me give you a practical example
February 10 this year. Tongli cement trading that day, you see the main shipping finished
from any technical analysis knowledge you can find on the Internet, I can tell you for sure that I can't see it
it can only be judged from the chip side
at the end of 2014 and the beginning of 2015, Tongli cement had a continuous and intensive block trading record for a period of time. You can make your own inquiry. What you buy is the business department on Huayuan road in Zhengzhou, and then Tongli cement company is in Zhengzhou. From this, you can guess that what you buy in this block transaction is internal members of the company
of course, it's just a conjecture, but in the first quarter of 2015, only the second largest shareholder of Tongli cement increased the purchase amount of this block transaction. So here's 100% evidence
on February 10, this year, in the dragon and tiger list of Tongli cement, you can see for yourself who is the number one seller
Garden Road, Zhengzhou
if the main force sells its seats in the dragon and tiger list, it means that the shipment has been finished. Otherwise, when others know how to continue to sell
so that night, you can understand the hot money that caused the trading limit to rise when you buy on the same day. On the second trading day, you have to kill more and run away regardless of the cost. For this, you can compare the list of the top five in the dragon and tiger list on February 10 with the list of the top five in the next trading day
then Tongli cement has been falling now
each of these conditions is real data, not illusory figures or indicators. You can feel it for yourself
