2013 blockchain entered

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. At present, blockchain technology is in the stage of rapid development. In the past two years, China has invested a lot of funds and talents in this area
technical personnel can learn this technology, while non-technical personnel can start from the instry media and instry community
If an enterprise needs to develop blockchain applications, it can entrust a professional third-party company. In Guangzhou, today's technology is good.

3. Blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage

First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchain

5. 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.

Blockchain instry development trend analysis technology has broad application prospects

with the characteristics of point-to-point payment, openness and transparency, the most direct application field of blockchain technology application is payment field. However, there are many pain points in domestic ticketing instry, such as too many agent levels, rampant scalpers, selling more than one ticket, fake tickets, lack of credit, etc, It can be solved by blockchain technology. The traditional ticketing mode needs the support of centralized facilities such as the third-party ticketing platform, and the information is extremely asymmetric. The new ticketing mode based on blockchain technology can realize point-to-point transaction, and the whole process is transparent and traceable

data source: the financial field of blockchain + application sorted out by prospective instry research institute is reshaping the financial instry pattern

the open and tamperable attribute of blockchain technology provides the possibility for decentralized trust mechanism,
has the potential to change the financial infrastructure. All kinds of financial assets, such as equity, bonds, bills, warehouse receipts, fund shares, etc., can be integrated into the blockchain ledger to become digital assets on the blockchain. They can be stored, transferred and traded on the blockchain, which makes them have a very broad application prospect in the financial field

by recing the cost of cross-border payment, securities trading and compliance, blockchain technology can save banks $15 billion to $20 billion a year

through the application of intelligent contract, blockchain + insurance can realize automatic claim settlement of insurance policy. Insurance institutions have high management and operation costs, and the data on the blockchain is true and reliable, which can effectively simplify the processing process of policy claims. In addition, the blockchain technology can realize the digital management of personal data, simplify information authentication, and help to trace the history of data

entertainment of blockchain + application: the development ecology of blockchain has taken shape, and the media instry may become the main beneficiary

blockchain technology can be widely used in news, games, picture right and other entertainment fields

blockchain technology will bring great changes to the underlying structure of the game and have a great impact on the current game instry. Gamers now have gatekeepers (centralized organizations) to decide prices, tax, censor users, control content, and profit from data. Through the decentralized platform, consumers can socialize and trade without mediation, providing more control and flexibility for game players in the game experience

blockchain + applied supply chain: it can improve the transparency of the supply chain, establish a new supply chain system

blockchain technology can improve the transparency, traceability and security of the supply chain, and promote a kind of trust and integrity. 1) At present, the supply chain has many disadvantages, such as long chain, many intermediate links, many interest joints, opaque and so on; 2)
the distributed bookkeeping technology of blockchain can register the transfer of goods on the ledger as a transaction, and determine the participants related to the proction chain management, as well as the proct price, date and location

Vpay, full name is visual payments, Chinese means virtual payment. It was first established in the United States as a platform for digital currency trading, such as bitcoin, quark coin, Leyte coin, etc

vpay is a payment platform for the circulation of digital currency, which was created by Mark & Chen 9642, a former technology executive of Google; Created by Milo. Vpay is a platform without borders, digital trading platform, international shopping mall platform, like Alipay and WeChat. The difference is that Vpay is developed by the most popular block chain technology in the financial circle since 2017. It can achieve cross border transfer without any spot, and there is no fee. p>

extended data

digital currency is short for digiccy, which is the abbreviation of "digital currency" in English, and is the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

8. TOBI, regular, can also guarantee the security of funds

9. In fact, many countries around the world are vigorously supporting the development of blockchain technology, including China. Since last year's speech, the development of China, especially blockchain + government affairs, has been particularly rapid. I believe that through the development of blockchain + government affairs to promote the popularity of blockchain, all kinds of fields are linked with blockchain and have practical application landing. At the same time, when there are practical social benefits, it means that the world has entered the era of blockchain 3.0. Many blockchain + government applications in China, such as Changsha's SMIC blockchain public service platform, are actually the first blockchain 3.0 era to lead Changsha into. I believe there will be better and wider promotion in the future.
