Huawei blockchain development

1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

2. There are few real baas that have been approved by the state. At present, the mainstream platforms are Tencent's tbaas, Jingdong Zhizhen chain jdchain, ant blockchain baas, Rongze's rbaas, network's Intelligent Cloud and Huawei's cloud BCS. Among them, the top four baas platforms are teams that have been researching and developing blockchain technology for several years, R & D capabilities are very strong.

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

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. Non small query, more is, but the daily trading volume is less than 10 billion do not consider

6. The monthly output is about 1.299 leytes, as follows:

7. 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

8. The core significance of the blockchain of four technologies is to establish the credit of all data between the participating parties, establish the trust relationship under the premise of creating unilateral ecological common protection under clear regulations, and then let the miners participate in the realization of credit.

9. In fact, the network has made some layout in the aspect of blockchain technology. The network totem blockchain does the right of pictures, the super chain does the application development platform of the underlying technology, the network intelligent cloud does the baas solution of blockchain, and the Xiaoman financial blockchain solution. Generally speaking, all those involved are involved, only in depth, Maybe Rongze blockchain will go deeper. Rongze blockchain team is a blockchain enterprise supported by the government in Nanjing. It has done a long time of research and development on the underlying technology of blockchain in government affairs, precision finance, medical treatment and new retail, and won various national blockchain awards. The patent strength of blockchain is no less than that of Huawei blockchain and ant blockchain, At the business development level, there are also strategic cooperation between global enterprises such as Starbucks and KFC, as well as some business cooperation at the government level. In the field of blockchain, Rongze blockchain has been doing well, which is no worse than network blockchain.
