Ⅰ The relationship between digital currency and blockchain

1. Blockchain and digital currency complement each other and are inseparable. Blockchain is one of the means of digital currency circulation.
2. Blockchain is the theoretical basis of digital currency. Digital currency is established on the basis of blockchain technology. Blockchain has certain guarantees for the security of digital currency. At the same time, digital currency is a block chain. The most successful application of chain technology.
Extended information: 1. Digital currency is an unregulated, digital currency, usually issued and managed by developers, and accepted and used by members of specific virtual communities. The European Banking Authority defines virtual currency as: a digital representation of value that is not issued by a central bank or authority and is not linked to a legal currency, but which, because it is accepted by the public, can be used as a means of payment or can be transferred, stored or traded electronically. .
2. Digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency mainly reflect three aspects: ① Because it comes from certain open algorithms, digital currency has no issuing entity, so no person or institution can control its issuance; ② Since the number of algorithm solutions is determined, the digital currency The total amount of currency is fixed, which fundamentally eliminates the possibility of inflation caused by excessive issuance of virtual currency; ③ Since the transaction process requires the approval of each node in the network, the transaction process of digital currency is safe enough.
3. The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof of work and algorithms, such as the use of proof of equity and SCrypt algorithms. Subsequently, the blockchain ecosystem continued to evolve around the world, with the emergence of initial coin offerings (ICO); the smart contract blockchain Ethereum; the asset tokenization sharing economy with “light ownership, heavy usage rights”; and blockchain countries. People are using this shared value system to develop decentralized computer programs in all walks of life and build decentralized autonomous organizations and decentralized autonomous communities around the world.

II Blockchain and Edge Computing What is Blockchain and Edge Computing Analysis

1. Blockchain: Blockchain is a concept of Bitcoin. It uses a block chain data structure to verify and store data, and uses a distributed node consensus algorithm to generate and update data. Utilize cryptographic methods to ensure the security of data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data. It is essentially a disintermediated database.

2. Edge computing: Edge computing is the ability to use an integrated platform of network, device computing, storage, etc., close to the source of data to provide corresponding services nearby. The main feature of edge computing is to provide services based on a regional model near the data end. Since the demand end and the service provider end are very close geographically, it is easier to provide fast and high-quality services, thus gaining popularity from Internet companies. .

3. Edge computing does not appear in recent years. As early as 2003, IBM cooperated with content distribution network CDN and cloud service provider AKAMAI in edge computing. In recent years, edge computing has also begun to cautiously carry out large-scale applications with the development of blockchain and 5G technology. Since edge computing needs to connect many devices scattered around, it also needs to form a distributed network. This kind of The structure is similar to the decentralization of blockchain, so in many cases, edge computing and blockchain can be well combined.

Ⅲ What is the relationship between blockchain and big data?

Blockchain and big data are both hot topics. Many people discuss them together and hope to conflict with more hot

points. Big data has become a huge industry long before the development of blockchain. Although blockchain is in the early stages of the

industry, many technologies and business models are still being explored.

In view of the relative maturity of the big data industry, we use big data as a starting point to study how blockchain technology interfaces with all aspects of the big data

industry.

The big data core industry chain can be roughly divided into the following three parts:

Product part: Including big data software product-related industries such as big data basic software and big data application software.

Data part: including data sources (data collection, data provision), data circulation (data transactions, data sharing

) and other industries directly related to data.

Services: related to big data infrastructure services (data storage, data transmission, data cleaning, data desensitization

, etc.), big data analysis services and big data application services services.

01 Product Section

The combination of software products and blockchain should be based on technology. Big data technology and blockchain technology have similarities: they

are distributed architectures.

But they also have obvious differences: the use of distributed technology in big data technology is computing resources - utilizing the computing resources of multiple

machines and will not be used by a single machine Processing tasks are distributed among multiple computers, each

machine. By processing different tasks, it integrates multiple computing resources to form powerful data processing capabilities.

Using distributed technology in blockchain allows multiple entities to trust each other. Each mainframe is controlled by itself

computers participate in the operation of the entire blockchain. Each computer runs basically the same task, and the entire blockchain

can achieve mutual trust between multiple entities through repeated redundant calculations.

From a technical perspective, big data technology uses trust to exchange computing resources, while blockchain technology uses computing resources to exchange trust. Due to the differences between the two, it is technically difficult to find a suitable collision point between big data and blockchain.

02 Data Part

In the various formats of the data part, the blockchain can find its place.

The chain is of little significance. However, if multiple entities are involved in data collection and data provision, blockchain can

come into its own.

In order to solve the trust problem between multiple entities, each entity broadcasts its own collected data to all consumers

and the hash of that data Values ​​are stored in the blockchain. Based on the hash value on the blockchain, each subject in the blockchain

can verify whether the complete data it received has been tampered with. Blockchain traceability and non-repudiation

make data provided by multiple parties more credible. At the same time, this method also helps maintain the integrity of big data

.

In the data circulation industry, blockchain can play a greater role. In the big data circulation industry, big data itself

is a digital asset. The transaction of digital assets can be realized through the blockchain. Additionally,

decentralized big data transactions implemented on the blockchain can reduce raw data connections. In a decentralized trading platform, only buyers and sellers

have access to the original data; on a centralized trading platform, the data intermediary serving as the trading center usually has access to the original

data. This increases data leakage and assets. Risk of Loss.

03 Service Part

In big data services, the service capabilities as digital assets are the same as the concepts of data and assets in data transactions

and Can be traded.

Blockchain can play an important role in the trading of such digital assets. At the same time, there are many new technologies that are constantly changing the blockchain, such as homomorphic encryption. Homomorphic encryption is an important technology that combines blockchain and big data services

. Homomorphic encryption can truly encrypt dataData service functions are converted into digital assets without the need for the big data service provider to copy the original data in the service. risk.

IV Bitcoin is dead, blockchain is reborn

(1) New concepts

My views on Bitcoin are constantly iteratively updated. But the essential thing will not change: whether this new thing will promote the development of productivity. We must first clarify the following concepts:

First, blockchain technology. This is a real development and innovation of productivity, which has very important practical and future significance. We must pay attention to the development of blockchain technology. We can no longer let the United States continue to occupy the same position as chip technology, one step behind and one step behind. This high ground. When I first learned about blockchain technology, it was as if a window had opened in my cognitive field, and my whole brain was illuminated. I felt that the practice of the concept of "decentralization" was incompatible with the communism of "Six hundred million Chinese states were conquered by Shun Yao", and At that time, everyone could be a part of the organism and "speak loudly, debate loudly, and post big-character posters", which had many similarities.

Blockchain has the characteristics of "unforgeable", "leaving traces throughout the process", "traceable", "open and transparent" and "collective maintenance". Forefathers such as Mao Zedong, Mao Zedong and Mao Zedong did not see decentralized In the Internet age, many of their assumptions were naturally realized in the Internet age - that is, in the progress of productivity. This is the great power of historical materialism.

Because of this, the country attaches great importance to the development of blockchain technology, which is a very correct decision. Blockchain has also been included in the "14th Five-Year Plan" as one of the seven key industries of the digital economy for the first time. Blockchain involves six subcategories out of three major categories: digital technology application industry, digital element driven industry, and digital efficiency improvement industry. The six subcategories are Internet data services in the digital technology application industry, new technology infrastructure construction in the digital factor-driven industry and digital efficiency improvement industry, digital general and special equipment manufacturing, digital transportation equipment manufacturing, and digital electrical machinery, equipment and instruments. Instrument manufacturing and other intelligent manufacturing.

Second, Bitcoin. Bitcoin is the opportunity and witness for the birth of blockchain technology. It is not productivity or technological progress, but one of the purposes or results of productivity development and technological progress. To make an analogy, blockchain technology is a newly born river, and Bitcoin is the pebbles washed down from the source of the river. For a certain group of people, it has collection value, and you can even understand that some people dug this river just for these pebbles.

The birth of Bitcoin was once revolutionary. For example (it is said) Satoshi Nakamoto’s original intention was to oppose the hegemony of the US dollar and decided to design a cryptocurrency that “will never depreciate”. But with the development of the times, Bitcoin is increasingly unable to be compared with blockchain technology. Does Bitcoin have value? Yes, the loss of digging machines and electricityConsumption is all value. Does Bitcoin have any use value? almost none. In addition to having a certain commemorative significance for a few people, it is mostly used in financial market speculation, black market transactions and money laundering.

Third, the behavior of mining and currency speculation. People use a large number of computers to find Bitcoins based on a specific algorithm, which is called "mining." Due to the particularity of the Bitcoin algorithm, mining becomes more difficult the further you go, and the more people there are, the more difficult it is to mine. Therefore, more and more machines must be invested and more and more electricity must be consumed. The behavior of currency speculation is speculation on the existing Bitcoin - what I criticize is the speculation on Bitcoin, not Bitcoin itself. It is like the tulip bubble back then. Flowers as beautiful as tulips are innocent.

Fourth, dogecoin, shit coin, S coin, etc. These are similar to Bitcoin, but are generated based on different algorithms. For example, Bitcoin has an upper limit, but Dogecoin does not have an upper limit. Cryptocurrencies are meaningful to certain groups (gangsters, money laundering groups, transnational criminal gangs), but if governments around the world do not recognize them, their meaning is very limited and can only be used for financial speculation. Some coins were even launched to satirize Bitcoin, but they themselves turned into speculative products and became "a satire of satires."

Fifth, air coins and garbage coins. These were rampant in the domestic market in the past few years, but later basically disappeared after being banned by state supervision. These coins have nothing to do with blockchain technology. Just write an algorithm in the background, and then use a hot spot to fool adults and aunts into investing. This is no different from blatant money fraud. I wish all air currency scammers will go to jail as soon as possible.

The following is a very classic picture from that year. A group of air coins and garbage coins held a blockchain conference. As a result, many aunts attended the meeting, because the aunts were big funders and investors. , so they are all important guests attending the meeting. It stands to reason that deceiving adults and aunties into buying some health products or something like that will have a placebo effect, and deceiving them into buying air coins has really been a sin for eight lifetimes.

(2) New Situation

The continuous development of productivity has brought about new situations, so my evaluation of Bitcoin is also changing dynamically.

I used to think that Bitcoin was firstly in line with the trend of electronic currency, and secondly, it was in line with the decentralization process of the Internet. It might also be able to combat the hegemony of the U.S. dollar. Satoshi Nakamoto is a fucking genius. To be honest, blockchain technology once really represented the development direction of advanced productivity, and Bitcoin was the best "medal" of blockchain technology. I really yearned for it. However, the greed of capital and human nature can turn all advanced productive forces into speculative activities. When the "gold rush" of the new era comes, Bitcoin has even become a waste of productivity - power resources, graphics cards, hard drives and other production tools have become their speculation tools, a large amount of resourcesIt was used in speculation and waste.

Human beings really have the ability to turn any genius setting into a speculative game - it was originally a witness to the value of blockchain in the development of productivity, but it turned into an act of crazy mining and waste of productivity; it was originally The concept of anti-tradition, anti-authority and decentralization turned into a carnival of leek-cutting on the exchange. My current attitude is this: I still recognize Bitcoin, but I do not recognize the behavior of speculating on Bitcoin; as for those garbage coins, air coins, virtual coins, and game coins, these things are really not worth mentioning, and they will be swept away sooner or later. The trash can of history.

As I said above, it is difficult to cite such an example in human history: a lot of value (undifferentiated human labor condensed in it) was consumed, but a rarely used product was produced. Something of value. In the past, speculative products, such as stocks, were either value or commercial paper; tulips and the like were useful to smell and look at. As for Bitcoin alone, it’s hard to imagine what use value it has other than speculation and money laundering. This is really a new page in human development – ​​we actually invented something that costs a lot of money but has no use value at all. .

As the title of this article says: It’s shameful to waste food, but what about wasting productivity? Bitcoin speculation has turned into a huge waste of productivity. According to the latest statistics from the University of Cambridge, the power consumption of Bitcoin mining alone reaches approximately 133.68 terawatt hours per year, and 1 terawatt hour is equal to 1 billion kilowatt hours of electricity. This figure basically exceeds the annual electricity consumption of Sweden, which ranks 27th in the world in terms of electricity consumption. In my country, most Bitcoin mining machines are located in Inner Mongolia, Sichuan, Yunnan, and Xinjiang. Because these places are rich in resources, electricity prices are low. China's annual electricity consumption for such activities is expected to peak at about 297 terawatt hours (one terawatt hour equals one billion kilowatt-hours of electricity) in 2024, exceeding Italy's electricity consumption in 2016; annual carbon emissions will also rise to 130 million tons, exceeding the Czech Republic’s total greenhouse gas emissions in 2016.

Currently, electricity consumption across the country is very tight. Guangzhou, Zhejiang and other places are restricting industrial electricity consumption. There are also long-term indicators of carbon neutrality. If we don’t crack down on this mining behavior, It’s really unreasonable.

What’s more, in addition to the waste of productivity, there are also financial risks. As mentioned above, domestic and foreign Bitcoin transactions are inevitably accompanied by risks such as black market trading, money laundering, and capital outflows—this is a problem at the macro level; at the micro level, the currency trading market fluctuates sharply and plummets 24 hours a day. For everyone, For individual investors, these are uncontrollable risks.

On May 21 this year, the Financial Stability and Development Committee of the State Council further requested: "Crack down on Bitcoin mining and trading activities." In the next step, targeted measures should be taken to carry out centralized rectification activities on virtual currency mining and trading activities to protect the property safety of investors.Maintain economic and financial order. Financial management departments should intensify the crackdown on illegal mining and trading activities of virtual currencies, maintain normal economic and financial order, and create a better environment for the official launch of my country's digital renminbi. Institutions and platforms that illegally participate in virtual currency transactions, speculation, or provide support services should be dealt with in a timely manner in conjunction with the judicial department to increase the cost of violating laws and regulations and increase the deterrence of rectification activities. For Bitcoin mining projects, all localities should comprehensively clean up and shut down in a timely manner.

It is difficult for mining behavior to survive without stepping on the three red lines of carbon emissions, financial systemic risks, and capital flight.

(3) Eternal Greed

Satoshi Nakamoto designed the rules of Bitcoin in order to challenge the hegemony of the US dollar, and now the currency market has become an arena for capital to pursue profits. I have to lament that capital has turned any revolutionary thing into its own slave. In the past, the "currency circle" was divided into the "coin party" and the "chain party" - because whether the currency or the chain comes first is a chicken-and-egg problem, and it is unclear. Therefore, the Bitcoin Party believes that blockchain technology serves cryptocurrencies, and cryptocurrencies will eventually unify the future of finance; while the Chain Party believes that the application of blockchain technology far exceeds cryptocurrencies, and Bitcoin is just the son of blockchain. .

At present, it seems that the chain party has won a great victory, and there are not many real currency parties left, and they have basically become eager speculators. Nowadays, the so-called currency circle is just to give oneself a high status. The essence is gambling: the former dog gamblers have become pioneer currency speculators, and the former bookmakers have become technological innovation enterprises. I have been sincerely recommending to my friends who are micro-managing the stock market and speculating on currencies to go to Macau. It is simple and straightforward. The probability of getting rich overnight is much greater than speculating on currencies. Moreover, if you gamble a lot, you can also enjoy VIP treatment and a room. You’ll be reimbursed for travel expenses and drinks; even if you lose money, you’re still traveling and relaxing. The casinos in Macau are luxuriously decorated, with free drinks and a variety of delicious snacks, and there are daily activities such as Hawaiian hula, Free performances such as the Swan Lake ballet and vaudeville magic are much more enjoyable than staring at the pan in a rental house every day?

What's more, the casinos are century-old and are based on integrity. If you win a lot, they won't default on your money. , you will also be refunded the cost of food, accommodation and round-trip travel expenses. Look at the faces of these stupid exchanges - power outages, unplugging network cables, forced liquidation, account invalidation... I always laugh at those pioneering young people who are proud of themselves in the currency circle. Your industry is much lower than gambling. I also seriously suggest that friends who can't get rid of their "gambling addiction" should gamble for real. If you lose money, you can treat it as consumption and enjoy it. Isn't it better than being cut off by the exchange for nothing?

The above content is not about asking everyone to gamble. Anyone who gambles on dogs deserves to die. I just satirize the so-called "currency circle". I am afraid that some good brothers will take it seriously, so I still make a statement.

There is a plot in "The Lord of the Rings" that seems interesting now: Saruman said that the dwarves were too greedy and dug too deep, digging up ancient evil things. Why, I immediately thought of those people who mine Bitcoin hhhhh, they are so greedy. Not to mention the skyrocketing price of graphics cards, the prices of memory sticks, hard drives and the like have doubled, which is too exaggerated. Let’s wait and see what monsters modern miners will dig up.

In this situation, I just want to say the beautiful words in "The Lord of the Rings": You shall not pass! I sincerely hope that all speculators will be buried in the abyss of the mining disaster.

(4) Experience and Lessons

The following part is my own investment experience. I would like to share it with you. Just listen to the story and have fun and learn from it. The best lesson is to learn from experience, if not, just keep it in mind: when there is not enough information, try to stay away from the financial product speculation market.

In 2014, I was studying in Hong Kong for graduate school. A senior I met on Renren said to me: "Now that you have a Hong Kong ID card and a Hong Kong bank account, it is very convenient to buy Bitcoin. You can learn about it, buy it and give it a try, it’s a rare opportunity.” I have always admired this senior and valued his advice, so I went to learn about Bitcoin. At that time, I had just read Kevin Kelly's "Losing Control", which seemed to open the door to a new world; I also learned about the principles of blockchain and felt that Satoshi Nakamoto was so awesome, and I felt that I was attracted by these two great gods. Took virginity. So naturally I am very positive about Bitcoin and feel that this is a new page in the history of human finance.

Although the ideal is full, the reality is very skinny. The biggest problem I face is - no money. I was still a student at the time, and I was living a very tight life with my family's living expenses. The rent and housing prices in Hong Kong were surprisingly high. Naturally, things like investment were put on hold for the time being. However, after the first half of the semester that year, there happened to be an opportunity to apply for a half-term scholarship (all sponsored by various wealthy companies in Hong Kong), so I applied and actually got a first-class scholarship (there was also a Special class), it seemed to be 5,500 Hong Kong dollars, which was a huge sum of money for me at that time.

I applied before the Christmas holidays, and I got the money the following year. I used the money to buy a pen to treat myself, and the remaining money bought two full Bitcoins - I remember at that time The price seems to be less than 2,000 Hong Kong dollars. It is a bit old and there must be a difference. So this article is definitely not a headline-grabber. For me, the money at that time was a super heavy position, and it had the nature of a stud.

Someone must have started to calculate how much money I made - when I bought it, it was three to four hundred dollars, and it rose to more than sixty thousand dollars, so now it is hundreds of thousands... This is a trap Misunderstandings in thinking patterns. I bought it for less than 2,000 RMB. When the price increased to 4,000, I liquidated all my positions... No.Laugh, this is the plot of "Charlotte's Trouble", everyone laughs at Dasha Chun, everyone is Dasha Chun...

But investing is not from God's perspective, you Anyone can understand living backwards. At that time, the doubling of Bitcoin was an invincible profit that I had never encountered before. It would be difficult for a young man who had just graduated to work to control it, right? Who knew it would rise so much and dozens of times later.

That’s right, it’s very true. There are always rich people who tell me after listening to this story that you have to be able to hold it. I know the nonsense, but you rich people use it to invest. The money is only one-Nth of your pocket money. You may not be able to use this money in your lifetime. Can’t you handle it? For me, investment income is a huge sum of money that can greatly improve the quality of life. I am sure of my mentality. It's different. You must worry about gains and losses. If you can hold it, you'll be damned. To put it bluntly, the economic foundations are different, so these investment techniques are useless.

Of course, it must be said strictly that Dashachun and I are still different - after all, it is the effect of a comedy movie. After I sold it, I continued to pay attention to the Bitcoin market. Later, I felt that it still had investment value and bought it back. This was not a one-time deal. I later sold, bought, and sold, and became a nasty speculator. Finally one day I woke up.

It was a good time to speculate in Bitcoin at that time, and I did make a lot of money - this is nothing to admit. However, Bitcoin can be traded 24 hours a day, and there is no such thing as a daily limit. The price rises and falls every day, just like riding a roller coaster. You have to keep an eye on the market all the time, and your mood rises and falls with the price. If you can't help it, you want to micro-manage. .

After a while, life like this became boring. My life was kidnapped by Bitcoin. The meaning of life is the ups and downs. I happened to be studying the "alienation" theory at that time, and I was deeply inspired. The rise and fall of Bitcoin "defined" my meaning, making people become "non-human". I am not living for myself, I am living for Bitcoin. And alive.

People should be the masters of things, but they cannot be the servants of things. After thinking about this, I liquidated all my Bitcoins and kept one as a souvenir. Now, no matter how much Bitcoin grows or plummets, it still doesn't stir up any emotion in my heart. When I decide not to use this currency to circulate in the market, it loses its meaning in external pricing and is just a "thing". I have thought about it. If I have a child in the future, I will make the USB flash drive that holds the Bitcoin wallet into a pendant and hang it around his neck. This is a contemporary gift from the previous generation, as a symbol of the development of human productivity and various wonderful social phenomena. A testimony.

Block Pioneer animation video helps you understand what blockchain is, simple and easy to understand

What is blockchain, Mao Bei belongs to the blockchain?

Answer: Maobei does not belong to the blockchain, but only uses blockchain technology. The characteristic of the blockchain is that everything that happens will be recorded and cannot be deleted or changed.

Blockchain, what is a block

Comprehensive interpretation of blockchain

When talking about blockchain, people always compare it with Bitcoin. On October 31, 2008, a person named "Satoshi Nakamoto" sent an email to a cryptography email group, claiming, "I have been working on a new electronic cash system, which is completely peer-to-peer and does not require Any trusted third party.” He launched a new system using Bitcoin as the transaction currency.

What is blockchain technology? What is blockchain?

Blockchain is a distributed shared accounting technology. What it wants to do is to allow all parties involved to establish a trust relationship at the technical level.

Blockchain can be roughly divided into two levels. One is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, transformation based on the blockchain, Optimize or innovate applications.

What is the core meaning of blockchain? Our understanding is that the core meaning of blockchain is to establish data credit among participants, and to create a single transaction under clear regulations through unilateral confrontation. The ecology of all aspects jointly guarantees complete opportunities. This is a system. This establishment can end the problems before the blockchain. Before the blockchain, it was impossible to achieve new sharing when data was shared, even if it was targeted. It just gives you an interface. After the blockchain is established, the participants can realize the sharing of credit.

What are the underlying platforms of blockchain?

Answer: There are mainly the following categories:

1. Bitcoin. The earliest blockchain development was based on the Bitcoin blockchain network. Since Bitcoin is the most widely used and truly decentralized in the world, in terms of blockchain applications, Bitcoin is the most widely used blockchain in the world. A strong anchor with the greatest authority.

2. Ethereum. It can be said that apart from Bitcoin, Ethereum is currently the most eye-catching blockchain platform. Ethereum is a Turing-complete blockchain one-stop development platform that uses multiple programming languages ​​to implement protocols. It uses a client written in Go language as the default client (i.e., the method of interacting with the Ethereum network, and supports many other language client).

3. IBM HyperLedger. Also called fabric, its goal is to build a super ledger that is jointly maintained by the whole society. Fabric originated from IBM. Its original intention was to serve industrial production. IBM open sourced 44,000 lines of code, which is a great contribution and allows us to have The opportunity is so close to explore the principles of blockchain that are different from Bitcoin.

4. LISK. It is a new generation of blockchain platform that allows JavaScript (Javascript technology again), Engineers Attention) develops and distributes decentralized applications using an easy-to-use, full-featured ecological blockchain system.

5. Online recording blockchain platform. It is the research and development result of the underlying technology of the Wanglu blockchain and a basic platform capable of commercial delivery. In addition to serving the Wanglu public chain, the Wanglu blockchain platform is also the basic platform for Wanglu to create private chains and alliance chains for customers.

What is blockchain? What is blockchain for digital currencies?

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm that uses smart contracts composed of code to program and manipulate data.
Nowadays, mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea-based digital currency Puyin was developed based on blockchain technology.

What is blockchain

The essence of blockchain is a decentralized accounting system, and Bitcoin is the currency that "exists in digital form" carried on this system. Blockchain is a system behind Bitcoin that consists of credit records and the settlement of credit records.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system [1].
Blockchain is an important concept of Bitcoin. The "2014-2016 Global Bitcoin Development Research Report" released by Huobi.com, Tsinghua University PBC School of Finance Internet Finance Laboratory and Sina Technology mentioned the area. Blockchain is the underlying technology and infrastructure of Bitcoin [2]. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block< br /> The evolution of blockchain is:
▪ Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0— —IFMChain, blockchain officially links mobile terminals

VI What is the development of blockchain technology in improving the ability to use and manage blockchain technology?Play a greater role

Improve the ability to use and manage blockchain technology so that blockchain technology can play a greater role in economic and social development.

Blockchain is a chain composed of blocks one after another. A certain amount of information is stored in each block, and they are connected into a chain according to the time sequence of their respective generation. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe.

Generalized blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission. and access security, a new distributed infrastructure and computing paradigm that utilizes smart contracts composed of automated scripts to program and manipulate data.

Ⅶ Bitcherry BCHC proposed "Blockchain 4.0" to promote the application practice of blockchain and e-commerce industry

With the continuous development of blockchain technology, it seems that many industries want to It has something to do with the blockchain, and there is a popular saying in the world: "Those who get the blockchain will win the world." So is this blockchain really as amazing as everyone says? How will blockchain finally be implemented? Today, let’s first talk to you about the application practice of blockchain in the field of “e-commerce”.

First, let’s briefly review what is e-commerce? E-commerce was born in the 1990s. It is a business activity that uses information network technology as a means and commodity exchange as the center and side. We call e-commerce "EC" for short. Many people think it is the ultimate major commercial use of the Internet, so they call it an epoch-making symbol.

According to data from US market research company Forrester, by the end of 2018, China’s e-commerce market is expected to reach US$1.1 trillion, becoming the world’s first trillion-dollar e-commerce market. The report points out that by 2022, China's e-commerce market will reach US$1.8 trillion, far exceeding the United States and Japan.

With the expansion of e-commerce, it has also greatly promoted the development of logistics, customer service and other industries. But at the same time, it has also brought about many problems. According to big data from the e-commerce consumer dispute mediation platform, the number of complaint cases accepted in the first half of 2018 increased by 66.93% year-on-year, and the growth rate was much higher than in previous years.

In order to solve the pain points of e-commerce in aspects such as counterfeit goods, logistics, integrity, and supervision, major companies and platforms are also showing off their skills and tricks. The most eye-catching one is our protagonist: blockchain. So how does it solve these problems?

First, supervise the production process of goods.

Second, trace and track the transportation of goods.

Third, guarantee product sales and after-sales service.

Fourth, protect user privacy.

The distributed e-commerce platform Bitcherry BCHC solves the platform trust crisis

Bitcherry BCHC is the world’s first distributed e-commerce platform. It is based on blockchain technology and is committed to To create a super ecology covering all aspects of clothing, food, housing and transportation. In the community ecology, all participants, such as users, merchants, super nodes, operating nodes, etc., use the token system for everyone's participation and economic sharing to open up the online and offline O2O e-commerce system, making the entire ecology healthy and autonomous. , develop healthily.

It is understood that the distributed e-commerce network has multiple payment methods, distributed sharing mechanisms, behavioral token incentives, distributed open platforms, multi-industry and multi-community access, and operating nodes around the world. , decentralized distributed business organizations, community self-propagation and ripples and other characteristics.

At present, consumer information is leaked, everyone has become a "digital labor", merchant profits are reduced, customer acquisition costs are increasing day by day, supply chain supervision is lacking, and product quality problems occur repeatedly, which is the problem for most centralized e-commerce companies. main pain points. Different from the centralized model of traditional e-commerce platforms, the underlying technology of distributed e-commerce platforms is a distributed accounting method that allows transaction data, dissemination, purchase, circulation and other behavioral data to be uploaded to the chain, making it open, transparent and non-tamperable. In distributed e-commerce based on blockchain technology, industry issues such as product traceability, logistics supervision, user evaluation and community incentives are all well-founded and well-founded. It returns data, traffic and value to the parties involved in the transaction, effectively solving the various shortcomings of centralized platforms.

To promote the implementation of blockchain in actual business scenarios, Bitcherry BCHC proposed "Blockchain 4.0"

According to the reporter's investigation, Bitcherry BCHC will adopt a two-stage implementation of "Blockchain 4.0" 4.0” target. Providing a public chain with high TPS and compatible with Ethereum smart contracts is the first phase of Bitcherry BCHC's measures to ensure the safe and efficient circulation of digital assets in the e-commerce ecosystem. In the second phase, Bitcherry BCHC will provide a large public chain environment that supports the e-commerce ecology - an e-commerce vertical blockchain network platform, allowing e-commerce operators to quickly realize digital operation transformation in the digital economy era and realize mutual cooperation in the e-commerce ecology. diversion. In addition, the reporter learned that the large public chain environment will also provide a governance structure, including a smart contract-based complaint mechanism, reputation scoring, arbitration mechanism, etc., to prevent fraud and damage to the interests of consumers and digital asset investors, and ensure the e-commerce ecosystem compliance and healthy development.

In terms of technology, Bitcherry BCHC public chain will combineBlockchain and DAG technology provide a chain network system, and the main chain guarantees the security of the entire system. Use signature algorithms, distributed storage, data operations, consensus mechanisms, message diffusion and other technologies to optimize the distributed e-commerce network architecture, and use a decentralized and non-tamperable structure to allow all participating entities in the Bitcherry BCHC ecosystem to establish a trust mechanism to achieve Second-level fast transaction verification by all parties is the main technical feature of the Bitcherry BCHC project.

ⅧWhy blockchain has become a hot technology and topic

The most important of these may be that the launch of Bitcoin based on blockchain technology has opened up a new The exploration and attempt of new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, notarization and verification, which have little relevance in traditional society (offline) and are fully applied in the online world (online), have given people the opportunity to adapt to The development of the Internet society provides alternative paths and unlimited imagination.
From its application in Bitcoin, blockchain is intuitively speaking, it combines encryption technology with the Internet to form a new set of data blocks (BLOCK) establishment, Bitcoin configuration, netizens Identity verification, as well as Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (adding factors such as block and transaction time marks) registration and verification Including verification, etc., the Internet protocol rules and accounting (Ledger) system of block connection (Blockchain), full encryption, and mutual authentication.
Ant Financial has applied blockchain technology to public welfare; China Post has applied blockchain technology to its core business and launched an asset custody system based on blockchain technology; Puyin Group has applied blockchain technology to its core business. Chain Technology launched the tea-based digital currency Puyin, which has a great influence in the digital currency circle. Jubi.com also opened a special trading area for Puyin.
