Blockchain infrastructure construction should be put on the agen

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. The definition of Chongqing jinwowo analysis blockchain technology is as follows:
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.

3. After the fire of new infrastructure, the blockchain instry will certainly have a good development. In the new infrastructure, data is becoming more and more important. Because the combination of blockchain and these technologies can ensure the credibility of data and ownership
an obvious phenomenon is that many provinces and cities are vigorously promoting the implementation of blockchain government service applications. For example, in Hunan, there are SMIC (Changsha) blockchain public platform, Loudi blockchain real estate registration platform and so on, which are blockchain government applications that have been implemented and well done.

4. One of the three conditions for large-scale implementation of blockchain applications is blockchain 3.0 technology, which can improve the performance, ease of use, operability and scalability of blockchain, and involves new technologies such as side chain, sub chain, cross chain, layering, fragmentation and zoning. According to Xiao Feng's observation, most of these technologies will mature in 2019, and the main network will go online. The launch of these new technologies is the premise of large-scale commercial application of blockchain. So from a technical point of view, after 2019, the large-scale commercial application of blockchain can be expected
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.

5. At present, it is 5173 and Taobao. Taobao is cheap. 5173 is about 20 percent

6. ASUS rx570 4G mining is certainly OK, 570 computing power is good, but ASUS graphics card is relatively expensive, it's better to buy the cost-effective Xunjing rx570 to mine, non mining will consume graphics card, so you can't buy expensive graphics card to mine,

7. Chongqing jinwowo analysis: it refers to the facilities that provide public services for the development of blockchain technology, instry and application. It is the basis for ensuring the normal progress of blockchain economic and social activities. It is the general condition for the survival and development of blockchain economy.

8. The characteristics of blockchain ensure that the information can not be tampered with and stored in a decentralized way, which can greatly promote data sharing, optimize business processes, rece operating costs, improve collaboration efficiency, and build a trusted system
at present, many local governments in China are promoting blockchain government application platforms, such as Chongqing's blockchain government platform, Guangzhou's tax chain platform, Hunan Changsha's SMIC blockchain public platform, and so on
from the perspective of technical characteristics, value and domestic cases, it is very necessary.

9. China's financial market has the same problems as China's whole society. Market economy and planned economy are interfered by the government. The government's administrative power is too large, which restricts the development of the market economy. As far as the current system is concerned, there is no way to break through the bottleneck unless it is reformed. Reform is not a simple market-oriented reform. Now the marginal benefit of economic reform is almost zero. The key is institutional reform

10.

Blockchain has the advantages of decentralization, distributed accounting, encryption and traceability, which can ensure the integrity and authenticity of the data on the chain. Once it is tampered or forged, it can be found. At the same time, because the blockchain has the characteristics of Distributed Accounting, even if the data on indivial nodes are deleted, other nodes can still save the data completely, ensuring the normal operation of the whole blockchain storage system

since the national development and Reform Commission incorporated the blockchain into the new infrastructure, the whole country has ushered in the upsurge of blockchain policy. The central and local governments have promulgated blockchain related policies one after another, taking the blockchain as the main breakthrough in the field of new economy and technology, building the future strategic competitive advantage, and the related application scenarios of blockchain are hot. The deep integration of blockchain and instry is the embodiment of maximizing the use of blockchain< based on "blockchain + justice + application", the easy security platform has successfully built a paperless one-stop service platform for business cooperation, providing E-contract, right protection and Internet notarization services for enterprises and authorities, and helping them solve the problems of high operating costs, chaotic management of contracts and seals, unsafe data storage and difficult accountability for network infringement. Completely transform the traditional business model, create a comprehensive upgrade of digital office
