Blockchain in its early stage

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. Blockchain technology is in its early stage, and has not yet formed a unified technical standard. Its scalability needs to be tested by large-scale practice; The application of blockchain is still in its infancy, and its application in some instries needs quantitative analysis, such as the financial instry. At present, the investment in financial infrastructure exceeds trillions. In the case that the existing technology has not been deployed and the use cases have been obtained, the financial instry will remain cautious about adopting blockchain technology; The blockchain instry is extremely short of cross-border talents who understand both technology and finance
the most valuable part of blockchain is not technology, but the idea behind it.
no technology is omnipotent, so is blockchain technology. As a trust connector, the greatest value it brings to the times is the concept of openness, openness and transparency behind it, and the spirit of building a business with trust and honesty. Based on this spirit, the blockchain technology is like the most impartial machine judge, so that every information in its hands can exist permanently in the world and be tested by future generations.

3. This concept was proposed in the white paper [1] of Nakamoto Tsung, who created the first block, namely "Genesis block"< On January 3, 2009, the founder of bitcoin, Mr. Nakamoto, left an unchangeable sentence in the genesis block:
"the times 03 / Jan / 2009 Chancellor on brink of second low for banks (on January 3, 2009, the chancellor of the exchequer was on the verge of implementing the second round of bank emergency assistance)."
at that time, the British Chancellor of the exchequer, darling, was forced to consider a second attempt to relieve the banking crisis, which was the headline of the front page article of the times that day
the time stamp service and existence proof of blockchain, the time generated by the first blockchain and the events that happened at that time are permanently preserved
BTCC, a bitcoin company, launched a service "Millennium chain" in 2015, namely blockchain lettering service, which is based on the above principles. Users can use this service to engrave text on the blockchain and save it permanently
bitcoin, Ruitai coin, Laite coin, dogcoin, Ethereum and other digital currencies will use blockchain technology.

4. In March 2016, Zhong Xiao, chairman and CEO of Rongze technology, was invited to visit the UK together with Professor Cai Weide, a well-known blockchain expert and head of Beihang's "digital society and blockchain" laboratory, to participate in the big data summit held by IEEE, the world's top academic organization, in Oxford - blockchain forum. Rongze technology has become the first batch of Chinese high-tech enterprises to participate in global blockchain discussions.

5. Blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.

It's only in the first tier cities that we know about this technology, but it's not very widely understood, let alone in other tier cities. The banking sector is also preparing to apply blockchain technology, but it has not really been applied. The financial instry also needs to apply it, but I don't know when. To be exact, blockchain is only in the initial stage of trial in China

in China, the instry in which blockchain has been applied is network mutual help bar. As I know, network mutual help platform concentric mutual help is the first real blockchain landing application in China. Through blockchain and big data technology, we can eliminate the defects of traditional network mutual help mode and establish an open and transparent new network mutual help platform

you can download their blockchain customer service end to experience it

It is the business hall:

1. Bank outlets are a new generation of mobile financial management application procts launched by wind information. Based on the current location of users, it provides users with financial life service software for quick location and information query of outlets. It is a professional financial management proct integrating bank directory, peripheral outlets and bank search functions

2. The location of bank outlets is mainly based on the different financial service needs of urban functional areas determined by layout planning. On the basis of full investigation, priority should be given to key economic areas, and the areas with good economic environment, great market potential, superior geographical location and convenient transportation should be selected to set up outlets

The 24-hour self-service bank is also called "unattended bank". It is mainly composed of ATM and CRS bank terminals. It can handle deposit, withdrawal, transfer, payment, inquiry and password modification

memorabilia of bank outlet procts:

1. On February 10, 2012,

Fund Manager 2.0 was released in all major Android channels. With its help, you can know the rise and fall of funds anytime and anywhere, and know where to buy the most preferential funds

2. Fund manager 1.0 was released in app store on January 28, 2012. The fund manager integrates public offering, private placement and securities financing procts to help you manage the fund from the aspects of fund information, fund ranking, fund screening, preferential rate and my assets

3. On January 25, 2012,

bank financial proct 1.0 was released in the app store. Bank financial procts collect the information of financial procts of 100 banks, push daily investment optimization, prompt high-yield procts at the first time, remind transfer calculation, and find the best return procts

8. Cornerstone stage refers to token based on blockchain technology, which is in the first stage of ICO. It's similar to the first round of angel investment.

The basic principles of blockchain are not difficult to understand. The basic concepts include:

< UL >

transaction: one operation leads to a change in the status of the account book, such as adding a record

block: recording the transactions and status results in a period of time is a consensus on the current account status

chain: it is composed of blocks in series according to the sequence of occurrence, and it is the log record of the whole state change

if the blockchain is regarded as a state machine, each transaction is an attempt to change the state, and the block generated by each consensus is that participants confirm the result of the state change caused by all the transaction contents in the block

10. Hunan now has two well-known blockchain projects: one is the SMIC blockchain public service platform in Changsha, and the other is the blockchain real estate platform in Loudi. It's the two most advanced platforms with landing effect. The procts they are making belong to the era of blockchain 3.0, but Hunan is still in the early stage of blockchain development, and the development of blockchain in Hunan is not complete and rich. However, the popularity of blockchain must be the development trend in the future, and the Internet has been popularized all over the world in only 20 or 30 years. I believe that the popularity of blockchain will be shorter.
