Founder of blockchain secret software

1. blockchain is a kind of technology, which is a distributed accounting technology. It is characterized by data traceability and non tampering. Cryptocurrency is a typical example of blockchain application. It is essentially a decentralized database. As the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods

2. Based on some characteristics of blockchain technology, the application fields of blockchain are relatively wide, especially in the financial instry, other fields such as medical treatment, authentication, smart contract, sharing economy, digital assets and so on. There are related requirements in each field, which need the development of software system for further application of blockchain technology. In my opinion, at present, only a small number of enterprises conct in-depth research on blockchain technology, while some large enterprises only conct application research and development on some internal requirements of enterprises, and few provide blockchain technology application system development like Yingtang Zhongchuang. Yingtang Zhongchuang has many solutions for the development of application software system of blockchain, which can be referred to one or two.

3. The development of blockchain can be divided into three stages. Melanie Swann, founder of blockchain Science Research Institute, in her book blockchain: blueprint and guide to new economy, according to the application and development of blockchain, it can be divided into three stages: blockchain 1.0, 2.0 and 3.0< br /> 
I. blockchain 1.0 cryptocurrency era (2008-2013)
&
in 2008, Nakamoto first proposed the concepts of bitcoin and blockchain, and then in January 2009, the first blockchain came out. At this stage, people pay more attention to the transaction of cryptocurrency, and blockchain is only used as the underlying technology to act as a "public account book"< br /> 
2. Blockchain 2.0 smart contract era (2014-2017)
&
in 2014, & quot; Blockchain 2.0 "has become the pronoun of decentralized blockchain database. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute the smart contract on the blockchain, and will be rewarded automatically after the execution. Because this transaction process does not need any intermediary, so people's privacy has been greatly protected< br /> 
III. blockchain 3.0 large scale application era (2018 -)
&
at this stage, people begin to build a completely decentralized data network, and the application of blockchain technology is no longer limited to the economic field, but expanded to the fields of art, law, real estate, hospital, human resources and so on.

4. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
from the above, blockchain belongs to software development
maybe you didn't ask clearly!

5.

If the time is t, the landing velocity is V, and the impact force is f. It can be calculated by the formula ft = MV

objects that fall only under the action of gravity without any resistance are called & quot; Free fall & quot;. An object, such as one that begins to fall from a static state under the action of the earth's gravity. The sky near the earth's surface can be regarded as a constant gravitational field. If the atmospheric resistance is not taken into account, the motion of the free falling body in this region is uniformly accelerated linear motion. Its acceleration is equal to the acceleration of gravity G

extended data:

the main characteristics of free falling body

the characteristics of free falling body motion are reflected in the word "free", which means that the object is stationary when it begins to fall, that is, the initial velocity v = 0. If the initial velocity of the object is not zero, even if it falls vertically, it cannot be regarded as a free falling body

(2) in the process of falling, the object is not affected by any other external forces (including air resistance) except gravity, and the resultant force of external forces is 0

(3) the falling time of any object is the same when it falls freely at the same height

6. On October 22, 2013, Qiao from Dongyang searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, Qiao found that the staff of the network trading platform were not online, and some normal trading proceres could not be implemented, and then reported the case to Dongyang Public Security Bureau
Dongyang Public Security Bureau of Zhejiang Province immediately started the investigation and found that Qiao was not the only one who suffered losses. Through efforts, the police of the special task force determined the identity of the manager of the GBL trading platform and implemented the pursuit in time. The first case of fraud on bitcoin trading platform in China was solved
lawyer analysis:
Zhang Yanlai, senior special researcher of China e-commerce research center and lawyer of Zhejiang Jin law firm, believes that virtual currency is not a new concept. Q-coin and online game currency have long been known by people. However, the emergence of bitcoin once again makes people realize the power of virtual currency. Compared with the traditional q-coin, the biggest feature of bitcoin is that it does not have a unified issuing agency. The generation of bitcoin completely depends on computer algorithms, and anyone can participate in the issuance of bitcoin
this makes it difficult to trace the source of bitcoin, which makes it a real virtual currency. The anonymity, cross-border and other Internet genes of bitcoin make people see a new form of currency that may circulate in the future society, so the pursuit and use of bitcoin also continued to rise in 2013. Some foreign governments have recognized the legal status of bitcoin. In China, some online stores have begun to use bitcoin for trading. Restaurants that accept "bitcoin" consumption have appeared in Beijing. The first "bitcoin" investment fund in China is also being raised. After the Ya'an earthquake, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan
of course, money laundering, fraud, gambling and so on will follow. This case is a typical case of fraud under the banner of bitcoin trading. As the first case of bitcoin fraud in China, the public security organs have also concted in-depth study and understanding of the professional knowledge related to bitcoin, and finally cracked the case. On December 5, 2013, the people's Bank of China, the Ministry of instry and information technology and other five ministries and commissions issued the notice on prevention of bitcoin risk, which first made it clear that bitcoin does not have the status of legal tender, and required financial institutions and Payment institutions not to price procts or services with bitcoin. The central bank believes that there are three risks in bitcoin Trading: high speculative risk; High risk of money laundering and being used by criminals or organizations. In the future, the future of bitcoin is not clear, especially in sovereign countries, which will take a prudent and conservative attitude towards currency, which involves financial order and national security. Therefore, the public should also raise enough risk awareness.

7. The blockchain instry is now mixed up with swindlers and doers. It's hard to get along in this instry without relationships and contacts

there are many reliable companies in the development of blockchain technology, such as the u-lab Laboratory of u.net in Australia and the incubators of major exchanges.

8. In theory, blockchain technology is very powerful and can be applied to many instries, which is comparable to the Internet in the 1990s. The Heshu blockchain of Shanghai Heshu Software Co., Ltd. is not the earliest blockchain technology developer in China, but a blockchain technology service provider with comprehensive strength ranking first in China.
