Three stages of blockchain development

1. 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.

2. 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.

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

4. The main advantages of blockchain are that it does not need intermediary participation, the process is efficient and transparent, the cost is very low, and the data is highly secure. Therefore, if there is any demand in these three aspects, the instry will have the opportunity to use blockchain technology.

5.

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

extended information:

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

6. I know whether Ethernet is the same thing. It's just a name of network communication materials. It's the same thing as broadband Internet. It's only different in units and categories. It's essentially an attribute of physical substances. That's all I know. And recently, I won't give a reward.

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

The sudden epidemic situation has pressed the "pause" button for many instries, but science and technology is the most effective means to fight against disasters. Blockchain technology has realized the combination with finance, logistics, supply chain, government affairs, public welfare, urban management and other application fields. At the same time, e to the imperfect development of technology, the role of blockchain in the prevention and control of the epidemic is very limited, so we need to explore deeper scenario applications

from the survey data, the main application directions of instrial blockchain in the post epidemic period include: traceability, financial (including insurance) supervision, collaborative sharing. Deposit certificate, digitization, credit investigation, digital asset transaction, etc

in the main application direction of instrial blockchain in the post epidemic period, more than 70% of enterprises choose traceability and financial (including insurance) supervision, in addition to collaborative sharing and certificate deposit. Digital also has more than 60% of the enterprise choice, compared with the low choice rate of credit reference and digital asset transaction, in which the choice rate of digital asset transaction is less than 50%, only 48%

to avoid risks and promote the healthy development of instrial blockchain

as an emerging technology development direction and instrial development field, blockchain has been widely concerned. The application of instrial blockchain is accelerating, which is mainly reflected in two aspects:

first, in the past, open source systems were represented in technology, and most of them were open source projects oriented to consumers, but now many projects oriented to instry and enterprise characteristics have been added; At the same time, more and more enterprises such as Internet giants and high-tech enterprises begin to enter this field, indicating that the era of instrial blockchain has come

secondly, the emergence of blockchain reces the threshold of trust and the cost of realization, enabling some financial and trade scenarios that could not be realized before to be realized. In this way, some new financial forms can be derived, providing more space for financial innovation

although the application of instrial blockchain is speeding up, it is still in an early stage of development. This is mainly reflected in the fact that blockchain technology alone can not fully solve the trust problems and information island problems between entities, and the emergence of blockchain technology also puts forward new problems for the current law and regulation

because of its decentralized and difficult to tamper with characteristics, blockchain has become a comprehensive subject driven by technology and deeply affecting economy, finance, society, organizational form and governance. In addition, blockchain technology is not yet fully mature in system stability, application security, business model and other aspects, which puts forward requirements for privacy protection and storage capacity of data on the chain

it should be noted that the current blockchain instry has been involved in many technical fields such as it, communication, security, cryptography and so on. What it needs is a kind of compound talents, which poses new challenges to personnel training and school ecation

the short-term impact of blockchain should be treated calmly to avoid overestimation. At the same time, it is necessary to further strengthen laws and regulations and supervision to avoid the possible risks of blockchain technology, so as to promote the healthy development of instrial blockchain

9. 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.

10.

It is a set of data transmission system that can ensure the absolute accuracy of information recording

most of the articles on the market are either too professional and lengthy, or the use cases are too simple to understand accurately. I hope that within 10 minutes, I can help you thoroughly understand the concept of blockchain and establish a visual and accurate understanding in your mind

What is
