Blockchain has a cycle of four years

1. blockchain has developed in five stages
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.

2. " Generally, there is only one approximate time cycle for the development of blockchain application app. For example, starting technology mainly depends on its functions and complexity. Generally, the development time is about 2-3 months. The specific time is estimated according to the customer's needs, mainly the development time. If the functions are multiple and more complex, there will be more things to develop and design, and the time will be longer. For example, in another case, the existing source code can meet the requirements, and only need to add or modify some functions will be very fast< br />"

3. The time limit for developing a blockchain application app, such as starting technology, is estimated according to the functionality of the app. Generally, the development time is about 2-3 months, and the specific time is estimated according to the needs of customers, mainly the development time. If the functions are multiple and more complex, there will be more things to develop and design, and the time will be longer. For example, in another case, the existing source code can meet the requirements, and only need to add or modify some functions will be very fast.

4. Depending on your basic level, if you have a certain technical foundation for development, it is relatively easy to learn
"chainman College" offers short weekend technical training courses for colleges with a certain programming foundation. You can investigate them and ask about your situation.

5. There are several entry points to look at: top-down policy support, credible blockchain data sharing, token and digital currency on blockchain. At present, in 2020, the blockchain instry is at an inflection point from barbaric growth to standardized operation and development, And the epidemic will also serve as one of the catalysts to promote the implementation of blockchain in the instry faster.

6. If it refers to the first block g up, on January 3, 2009, Nakamoto Cong g up the first block on a small server in Helsinki, the Netherlands, which is the so-called "Genesis block". For information about blockchain, you can learn more about it in mimacaijing.

7. Liu chain has been developing this technology. In the blockchain, every record of the coming and going of funds will be accurately recorded in all the block nodes, so there is no need to worry about the data being tampered with, and there is no need to worry about one party in the transaction refusing to admit after receiving the money.

8. At present, Internet breeding software includes all people raising cattle, Lenong's home, Aishang raising pig, chicken housekeeper, ugly ckling farm, etc. all people raising cattle, falling in love with raising pig and chicken housekeeper are income oriented apps with little user interaction. They are investment income oriented apps. Ugly ckling farm is an app developed by Shenzhen ugly ckling Innovation Technology Co., Ltd., focusing on user breeding experience, Real time online breeding and offline breeding can be synchronized. Those who have children at home and need to raise their own cks to supplement their families can raise their own cks and eat by themselves through this platform, which is visible in real time, green and pollution-free, and recommended by the wall.

9. Generally, there is only one approximate time cycle for the development of blockchain application app. For example, starting technology mainly depends on its functions and complexity. Generally, the development time is about 2-3 months. The specific time is estimated according to the customer's needs, mainly the development time. If the functions are multiple and more complex, there will be more things to develop and design, and the time will be longer. For example, in another case, the existing source code can meet the requirements, and only need to add or modify some functions will be very fast.

10. The analysis of jinwowo network is as follows:
many organizations pay more attention to how to apply blockchain technology to business, improve business efficiency or service quality, rather than stay in the underlying technology of blockchain itself
however, in order to apply blockchain, we must first master the technology and concept of blockchain, then select the application scenario, select blockchain, be familiar with the development technology of this kind of blockchain, and finally carry out the application development and business transformation of blockchain. The whole cycle is long.
