① Is blockchain the trend in the next ten years?

Blockchain is the biggest trend in the next ten years!
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 behind the times.
The concept of blockchain can be traced back to the end of 2008. A mysterious person named "Satoshi Nakamoto" published a paper "Bitcoin: A Peer-to-Peer Electronic Cash System" in the forum. , first proposed the concept of blockchain.
On January 3, 2009, the first block of the blockchain was born. This block is called the "original block".
Almost with the birth of blockchain technology, Bitcoin became the first thing to play its role. In the following years, Bitcoin gradually became popular around the world. In 2017, its crazy market made blockchain technology a Everyone knows.
The idea of ​​blockchain first appeared in the famous Bitcoin open source project. During the birth and development process of the Bitcoin project, it drew on technical achievements from many fields such as digital currency, cryptography, game theory, distributed systems, cybernetics, etc. It can be said that it draws on the strengths of many experts as its core support structure The blockchain technology is an eye-catching innovation.
Blockchain is a distributed database system participated by different nodes and an open ledger system.
Three major characteristics of blockchain
Compared with traditional centralized solutions, blockchain technology mainly has the following three characteristics:
The core idea of ​​blockchain is decentralization< br />In the blockchain system, the rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thus ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a serious hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.
The biggest disruption of blockchain is the establishment of credit
Theoretically, blockchain technology can make WeChat Pay and Alipay no longer valuable. "The Economist" gave a vivid metaphor to the blockchain: simply put, it is "a machine that creates trust." Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.
The collective maintenance of blockchain can reduce costs
Under a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and costs cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.
In one sentence, blockchain touches money, trust and power, which are the fundamentals for human survival.Base.
Its development has gone through 3 stages
1. Incubation period: 2009-2012, the economic form is dominated by Bitcoin and its industrial ecology.
2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.
3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.
The "Blockchain 2.0 Era" is coming
The application service layer is the driving force for the sustainable development of the blockchain, and is divided into three stages of application: 1.0, 2.0, and 3.0.
Programmable Currency: Blockchain 1.0 Application
Programmable Currency is a digital currency represented by Bitcoin, but it is not the legal currency of any country or region, and no government authority provides it with guarantee.
Programmable Finance: Blockchain 2.0 Applications
Blockchain 2.0 applications have added the concept of "smart contracts" (using program algorithms to replace humans to execute contracts). This allows the blockchain to expand from the initial currency system to the registration and transfer of equity, debt and property rights, the transaction and execution of securities and financial contracts, and even financial fields such as gambling and anti-counterfeiting.
Programmable Society: Blockchain 3.0 Application
Blockchain is the core of the Internet of Value and can confirm, measure and store property rights for every information and byte that represents value in the Internet. It can not only record transactions in the financial industry, but can record almost anything of value that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the entire society.
Currently, blockchain applications have begun to surpass Bitcoin (Blockchain 1.0), enter the Blockchain 1.5 era, and transition to the financial field (Blockchain 2.0).
In the next 3-5 years, blockchain may transcend the financial field and enter the social notarization and intelligent fields (blockchain 3.0), including identity authentication, notarization, arbitration, auditing, domain names, logistics, medical, In areas such as mail, visas, and voting, the scope of application has expanded to the entire society. Blockchain technology may become a bottom-level protocol for the "Internet of Everything."
Currently, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Along with this comes more people’s attention, “In the next 30 years, new technologies will be integrated into all aspects of traditional industries, and human society will be turned upside down. No matter who you are or where you are, all of us will Everyone will be part of this big change.”
This is the status quo, and blockchain has given 90 The opportunity of the next era, but 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 bystander.
It’s time to invest more of your energy and pay attention to blockchain technology.
The average annual salary of blockchain positions in my country has reached more than 300,000, and the annual salary of some companies has reached more than 1 million. The monthly salary of fresh graduates in the blockchain industry in Beijing, Shanghai and other places has exceeded 20k! The post-90s generation may seize the dividends of the times and become the next Alibaba in the future! If you miss it, you may regret it for ten years.

② Blockchain is the last chance for ordinary people! Can you seize it?

Missed the era of making money in stocks, missed the era of making money in real estate, missed the era of e-commerce Era, it doesn’t matter if you miss the era of big data, just grasp the blockchain. If you can’t grasp this anymore, it’s basically over.

Since entering 2018, more and more people have become aware of the blockchain. Many people have begun to blindly invest in projects. They do not study the projects carefully and always want to play conceptual projects. Whichever side of the platform the guys are standing on, the leeks hurriedly follow the platform. What you don’t know is that when the big guys talk about blockchain, they are nothing more than building momentum for themselves and announcing to the outside world that they have entered the market. They are most afraid that they will not be able to follow. Follow the trend of the times and be forgotten by others.

Human abilities are limited, but the power of the times is unlimited, and so do you. Once you step into the blockchain era, you can realize your great dreams...

In 2018, whether at the national level or the enterprise level, blockchain has become the wave of the times. This is also a major trend that no one or any country can stop, because the long river of history is always moving forward. .

Just like the Internet will inevitably subvert traditional industries, blockchain will also inevitably subvert the traditional Internet.

We have not caught up with stocks, real estate, e-commerce, the Internet, and big data. Blockchain digital currency is a major change for our young people. Business.

CCTV host Zhang Quanling said: One day in the currency circle, ten years in the Internet! In 2018, the wealth created in the currency circle in one year is not comparable to that of other industries in a century or even a thousand years. Countless billionaires, tens of billions, and hundreds of billions will be born this year! Because the blockchain technology industry is developing rapidly, 40 billion yuan of money flows into this industry every day, 400 billion yuan in 10 days, 4 trillion yuan in 100 days, and 40 trillion yuan in 1,000 days. Money poured in.

In other words, in the next 2 to 3 years, tens of trillions of dollars will pour into the currency circle, forming a new global digital currency capital market. Comparable to the stock market. NowThe first wave of people participating in the currency circle are just like the first wave of people participating in the stock market in the 1990s. They are even more crazy and making a lot of money.

Therefore, choice is greater than effort, and trend development cannot be stopped. Everyone needs to use a wise eye to see the future development of this trend.

"Blockchain is the last chance for the poor!"

As an insider, I also think so. Blockchain is the last chance for the grassroots to make a comeback, really. If you miss it, there’s no use looking for the rope!

This once-in-500-year financial change requires us to embrace the blockchain with all our strength and enthusiasm.

Every time the so-called "bubble economy" strikes, it will also be accompanied by the arrival of huge value. If we live the life of office workers from 9 to 5, we will never achieve financial freedom. , if you want to make big money, which one does not achieve wealth freedom through the value generated by bubbles. Are real estate and stocks a bubble economy? How to add value without instant noodles? Although this blockchain bear market may last much longer than everyone expected, what I want to tell you is that blockchain is still in the dividend period. Although more and more people know about blockchain now, they are just On the surface, I know that not many people are participating

I reiterate that blockchain is the last chance for ordinary people to overtake us in a corner. This is a financial change that only happens once in 500 years. What we grassroots need to do is The most important thing is to be prepared, join, learn and struggle, and you will definitely have unexpected gains.

③ What exactly is blockchain? Which blockchains have physical applications

What is blockchain?

Official definition: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission consensus mechanism encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes, all the data on the Internet will The data is packed into a complete package, and this complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged to form a distribution. ledger, this is the blockchain.

It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.

Financial Industry

Blockchain should be used the most in the financial industry.

For example, in May 2017, OMG (Young Momo Coin), omise announced and paidAlipay cooperates with Alipay to launch an e-wallet that integrates the "Alipay" payment solution into its own payment service suite to help local e-commerce merchants in Thailand accept online payment transactions from Chinese tourists.

Another example is PPT, which is a financial transaction system for bills based on blockchain.

Gaming

The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.

For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.

For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require functions such as event planning, market production, providing information and analysis to traders, reporting event results, and of course collection and payment.

I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.

Internet of Things

The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.

For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. Data sources can connect to any node in the entire network, then publish data, and the network will immediately send it to subscribers. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.

Game industry

For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.

For example, MANA is a distributed shared virtual platform. On this platform, users can browse and discover content and interact with other people and entities. Users can also claim ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.

There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.

The development of human society is actually like the blockchain, it is irreversible and unstoppable. As far as I feel, the blockchain will enter thousands of households sooner or later. Regardless of whether it is bull or bear, hold it in your hands. Value coins and Flush have started quoting digital currencies, indicating that society is accepting it step by step.Regardless, no country or person can stop the power of social development.

④ What is blockchain and what is its use? Will it become a new trend?

Three questions about blockchain (economic hotspot)

In recent times, related to Bitcoin The news about currency is very eye-catching, and blockchain has also become popular. In the capital market, the stock prices of various blockchain concept stocks rise and fall like a thrilling roller coaster. It can be seen from the responsive capital market that blockchain is on the forefront and has received great attention from all parties.

"Blockchain technology is essentially a database technology, specifically a ledger technology. The ledger records the asset changes and transactions of one or more accounts. In fact, it is A database with the simplest structure. The running accounts we usually write down in small notebooks and the statements sent by the bank are all typical account books." Wang Jun, chief researcher of Tencent Financial Technology Think Tank, said that security is an aspect of blockchain technology. Its major features are mainly reflected in two aspects: first, the distributed storage architecture, the more nodes, the higher the security of data storage; second, its tamper-proof and decentralized ingenious design, it is difficult for anyone to not follow the rules change the data.

Take online shopping transactions as an example. The traditional model is that the buyer purchases the goods and then transfers the money to the intermediary platform of a third-party payment institution. After the seller ships the goods and the buyer confirms receipt, the buyer will then notify the payment The institution transfers the money to the seller's account. The transaction model supported by blockchain technology is different. Buyers and sellers can trade directly without going through any intermediary platform. After the buyer and seller trade, the system releases the transaction information through broadcast. All hosts that receive the information record the transaction after confirming that the information is correct, which is equivalent to all hosts making data backups for this transaction. Even if there is a problem with a certain machine in the future, it will not affect the data recording, because there are countless machines as backup.

When it comes to blockchain, many people associate it with Bitcoin, and many people even equate blockchain with Bitcoin. He Fei said that Bitcoin is a presentation method of blockchain, but blockchain is not the same as Bitcoin. Blockchain is the underlying technology and infrastructure of Bitcoin, and Bitcoin is a successful application of blockchain, but it does not mean that blockchain can only be applied to Bitcoin.

What is the use of blockchain?

It can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, and anti-counterfeiting, but there are many applicable conditions

Financial services are the first application field of blockchain technology. The use of blockchain technology can solve pain points in many fields such as payment, asset management, and securities.

Take the payment field as an example. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, is high and involves many manual processes. The high fees also make it difficult to carry out micropayment business. The application of blockchain technology can help reduce the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing efficiency of payment services. In addition, blockchain technology provides paymentThe cost and efficiency advantages brought by the field enable financial institutions to better handle small cross-border payments that were previously considered unrealistic due to high costs, helping to achieve inclusive finance.

For example, in order to solve the problem of high reconciliation costs among financial institutions, in August 2016, WeBank and Shanghai Huarui Bank launched the Weilidai inter-institution reconciliation platform, which is also the first in production in China. Banking industry consortium chain application scenarios running in the environment. Zhang Kaixiang, chief architect of WeBank’s blockchain, believes that the high cost problem that the traditional “batch file reconciliation” model has not been able to solve for a long time is where blockchain technology comes in. Subsequently, Luoyang Bank and Changsha Bank also successively connected to the inter-institution reconciliation platform. Through blockchain technology, they optimized the inter-institution reconciliation process in the micro-loan business, achieving quasi-real-time reconciliation, improving operational efficiency, and reducing operating costs. Target. Up to now, the platform has been running stably for more than a year, maintaining zero failures, and the number of real transactions recorded has reached tens of millions.

In the field of public welfare, blockchain technology also has great potential. Ant Financial's first application scenario involving blockchain was public welfare, helping a group of hearing-impaired children obtain a donation, and then using blockchain technology to promote public welfare to be more open and transparent. Hu Danqing, senior product expert at Ant Financial Technology Lab, said: "The blockchain charity platform is like us building a post office on the Internet specifically for mailing funds. Every money donated by users, we will package it into a The package is delivered through the blockchain platform. Every time it passes through a node, we will stamp a postmark and finally deliver it to the recipient. This ensures that every money donated by users is transparent, traceable, and difficult to tamper with. ”

Blockchain technology can play a big role in combating counterfeit goods. Hu Danqing introduced that Ant Financial uses blockchain technology to trace the origin of authentic products. At present, there are some overseas shopping products from Australia and New Zealand, such as milk powder. You can use Alipay to scan the products to know whether they are genuine. "Unlike the previous self-entered product information by merchants, blockchain allows multiple 'bookkeepers' to complete accounting fairly, independently, and non-repudiation."

For financial supervision, blockchain Technology can also play a role. The "Financial Blockchain Underlying Platform FISCO BCOS White Paper" released by the Financial Blockchain Cooperation Alliance (Shenzhen) in 2017 believes that blockchain provides financial regulatory agencies with consistent and easy-to-audit data. Data analysis can supervise financial businesses faster and more accurately than traditional audit processes. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly enhance anti-money laundering efforts.

Some people in the industry believe that blockchain 1.0 is mainly aimed at digital currency; blockchain 2.0 is aimed at smart contracts and can be applied in the financial market; blockchain 3.0 will be applicable to more scenarios, and even Create a "blockchain era".

He Fei believes that blockchain can indeed solve the pain in many fields.It’s a bit difficult, but blockchain is not a panacea and has many applicable conditions.

For example, the decentralized nature of blockchain technology is suitable for scenarios involving multi-party participation. If it is only unilateral or bilateral participation, it will be of little value. Since each node needs to be checked, blockchain technology is not suitable for high-frequency trading activities.

For another example, blockchain emphasizes openness and transparency and is not suitable for scenarios with particularly high data privacy requirements.

Will blockchain become a new trend?

The technology is not yet mature, so we must be wary of concept hype, and we must distinguish between technological innovation and fund-raising innovation. We cannot use blockchain for the sake of blockchain

The concept of blockchain is so Will Fire become another “Internet+” in the future?

In recent years, the development ecosystem of blockchain has gradually been improved and enriched. Industry insiders believe that with national policy support, widespread attention and financial support, blockchain technology can achieve gradual and stable progress. Although the upside prospects of blockchain technology are broad, we must remain calm about this.

“Although the blockchain is currently very popular, we still believe that it is still in a very early stage.” Hu Danqing said that there is currently false enthusiasm in the blockchain concept, and it is not the technology that solves the problem. The real problem is that the focus is on raising funds to make money and hyping valuations. In particular, most of the so-called ICOs (Initial Coin Offerings) that are so popular are innovations in fundraising tools and have nothing to do with technological innovation.

Blockchain technology can indeed create great value, but some risks cannot be ignored.

“Blockchain technology is not yet mature, and its application scenarios are relatively limited. We should be more wary of the concept of capital market speculation.” He Fei said that behind the blockchain boom, there will inevitably be some gimmicks and speculation. Companies that do not really carry out business, but just try to make a profit in the capital market and leave. We must be careful to prevent the occurrence of "bad money driving out good money", causing institutions that really want to do business to withdraw from the market, affecting the development of blockchain technology. application.

Hu Danqing suggested that for the current blockchain craze, regulatory authorities should intervene more proactively, distinguish between technological innovation and fund-raising innovation, and encourage government organizations, credible experts, and industry participants to jointly help the public Identify and comprehensively curb fund-raising innovation in the name of blockchain, so that the actual controller of ICO must bear responsibility for the fund-raising behavior. "The basis for judging whether it is technological innovation or fund-raising innovation is actually very clear, that is, whether it starts with trust and whether it creates actual value by solving the trust problem."

Better promotion and use of blockchain technology in the future , it is necessary to continue to improve infrastructure and strengthen the formulation of relevant laws and policies.

Wang Jun believes that there is still room for optimization and improvement in core blockchain technologies such as consensus algorithms; on the other hand, the processing efficiency of blockchain is still difficult to reach that of some high-frequency application environments in reality. Require. At present, the mainstream blockchain technology platforms all originated from abroad. Domestic blockchain technology service providers must patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. own blockchainEnterprises that use application scenarios must actively embrace new things and scientifically evaluate their on-chain needs. They cannot use blockchain for the sake of blockchain.

He Fei believes that the government can introduce relevant policies to guide companies that are interested in participating in the research and development and application of blockchain technology, and at the same time clarify some suitable application scenarios of blockchain and areas encouraged by the state.

The "China Blockchain Technology and Application Development White Paper 2016" recommends that government departments at all levels learn from the advanced practices of developed countries and regions, combine the development of my country's blockchain technology and applications, and promptly introduce blockchain Technology and industrial development support policies focus on supporting key technology research, major demonstration projects, "mass entrepreneurship and innovation" platform construction, system solution research and development, and public service platform construction. At the same time, it is recommended that key domestic enterprises, scientific research, universities and user units strengthen cooperation to speed up research on core key technologies such as consensus mechanisms, programmable contracts, distributed storage, and digital signatures.

If it can bring money to the enterprise, it will become a hot topic.

⑤ What is the development trend of blockchain and the future development trend of blockchain

The development prospects of the blockchain industry are broad driven by the dual layers of policy and market
The dual layers of policy and market Driven by the epidemic, China's blockchain-related industries are expected to move from reality to reality
In the context of the rapid development of blockchain, China conforms to the needs of globalization, keeps up with international pace, and actively promotes research and standardization in domestic blockchain-related fields. formulation and industrial development. Compared with the background of increasingly strict supervision of digital currencies such as Bitcoin, support and encouragement for blockchain technology has reached a global consensus, and domestic blockchain technology will also receive national and local policies in the next few years. support. Driven by the dual layers of policy and market, blockchain-related industries are expected to move from reality to reality, and blockchain technology will accelerate the exploration of possible application scenarios.
Forecast of global blockchain market size
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, the global blockchain market size is expected to increase from 2017 to 2017. It will increase from US$411.5 million in 2022 to US$7.6837 billion in 2022, equivalent to a compound annual growth rate of 79.6%. Given the wide range of applications for distributed ledgers and the rising market value of cryptocurrencies, there is a strong need to improve transparency, security, efficiency and streamline processes, as well as blockchain as a service (
BaaS). As a hot topic of development, the blockchain market will expand rapidly. In addition, communication services, international trade, supply chain management, program platforms, payments, smart contracts, digital identity verification, etc. also urgently need blockchain technology and will create a large number of growth opportunities.
Blockchain, as an integrated application of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, has become a hot topic of research and discussion by international organizations such as the United Nations and the International Monetary Fund as well as many national governments in recent years. The industry has also increased investment. At present, the application of blockchain has extended to the Internet of Things, intelligent manufacturing, and supply chain management., digital asset trading and other fields will bring new opportunities to the development of new generation information technologies such as cloud computing, big data, and mobile Internet, and have the ability to trigger a new round of technological innovation and industrial transformation.
By 2022, the payment sector may occupy the largest share of the blockchain market
Relying on blockchain technology, instant payment of assets can be realized, which not only has the characteristics of non-tampering and digital identity verification, but also can provide Financial institutions and banks significantly save settlement costs. In addition, blockchain makes it possible to automate payments, eliminating the need for middlemen, saving labor costs and time for buyers and sellers. Thanks to the many advantages mentioned above, it is expected that the payment sector will be the most important segment in the entire blockchain market.
The fastest growing region will be Asia-Pacific
Blockchain service providers in the Asia-Pacific region are good at designing and developing user-friendly, cost-saving, and fast cryptocurrency platforms, extending blockchain to multiple Industry application tentacles. Both large enterprises and small and medium-sized enterprises are actively seeking venture financing and investing in the research and development of cutting-edge blockchain technology. In addition, the real estate industry in some countries in the Asia-Pacific region is expected to rapidly transform from semi-transparent to fully transparent, which will also help enhance the development prospects of blockchain in the Asia-Pacific region.

⑥ Is blockchain useful? What impact and prospects does blockchain have?

I believe everyone is no longer unfamiliar with the emerging technology of blockchain, because this is the current The most popular topic of the Spring Festival, many big guys in different industries are analyzing its role and prospects. Today we also do some research on the blockchain. Is the blockchain useful and what is the impact of the blockchain? and prospect analysis, I hope it can help everyone.
Is blockchain useful?
1. Banking: As a digital, secure and interference-proof account, blockchain realizes the core function of the banking industry: a safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking industry.
2. Payment and transfer: Blockchain technology can avoid complicated systems and create a more direct payment process between the payer and the payee. Whether it is a domestic transfer or a cross-border transfer, this method has its advantages. Low price, fast, and no intermediate handling fees.
3. Network security: Although the blockchain system is public, its verification, sending and other data exchange processes use advanced encryption technology. This technology not only ensures the correct source of data, but also ensures that the data is not intercepted during the process. If blockchain technology is more widely used, the probability of being attacked by hackers may also decrease, so people think that blockchain systems are more stable than traditional systems. One of the reasons why blockchain systems can reduce traditional network security risks is that they eliminate the need for middlemen.
4. Election: Everyone's vote "can never be modified or deleted by us - programmers, school administrators or students."
5. Smart contract: Smart contracts are actually on another object. actionA computer program that functions on. Like ordinary computer programs, smart contracts are also an "if-then" function, but blockchain technology enables the automatic filling of these "contracts" without manual intervention. Such contracts may eventually replace the legal merger industry's core business of drafting and managing contracts in both commercial and civil areas.
6. Stock trading: For many years, companies have been trying to simplify the process of buying, selling and trading stocks. Emerging blockchain technology startups believe they can go beyond the past, automating the entire process, improving security and efficiency.
What impact and prospects does blockchain have?
1. The dual impact of bringing wealth and risk:
The difference between blockchain technology and traditional Internet technology is that it chooses the high-risk financial industry as the entry point, but the financial field is full of Areas with many obstacles. Such direct entry has a dual impact: on the one hand, it can bring wealth effects to entrepreneurs relatively quickly; on the other hand, various risks will also come directly and violently.
2. Improve efficiency and reduce costs:
For physical finance, blockchain can maintain the fidelity in the process of transmitting information, such as personal credit information and other data, thereby avoiding many transaction costs and enabling large-scale Improve efficiency, this is the positive meaning it brings.
3. Control financial risks early and small:
Blockchain is cooperating with the innovation of digital currency, preventing over-insurance in the insurance industry, over-lending in bank mutual funds loans, and the integration of supply chain finance. , promote electronic identity recognition, etc., applicable to many industries and fields. In terms of financial security, many companies have also cooperated with regulatory authorities to build regulatory technology systems to help regulatory authorities monitor and provide early warning for the risks of Internet financial companies, so as to control financial risks early and at an early stage.
4. The owner of the data should be the user himself:
Blockchain is a technology worthy of attention, and it has relevant layouts in its own business and investment. Bitcoin and other electronic currencies are applications based on blockchain technology. They have certain currency functions and have certain use value. However, the main problem now is that the gap between the use value and the transaction price is too big. . ICO is a financing business model.
5. The darkest stage contains the most opportunities:
The darkest stage often contains the most opportunities. The application of blockchain is far more than just monetary and financial. For example, big data can be applied to the entire medical industry in the future. health field. If medical records and diagnosis data are shared to all different medical systems through big data blockchain, the efficiency of treating diseases and saving lives can be greatly improved.
The editor believes that the correct development prospect of blockchain is to "talk less about financial innovation, focus more on financial security, focus more on inclusive finance, and do more on medical care, health, and environmental protection."
The above is the blockchain brought to you by the editor. Is it useful? What impact and prospects does blockchain have? all content.

⑦ Let’s talk about blockchain while it’s hot

Let’s talk about blockchain while it’s hot
Blockchain is popular again
The Internet has become Victoria’s Secret’s T stage. Big bosses are wearing technical underwear, posing and looking sexy, and their leg hair is fluttering in the wind, and they are black and shiny. .
At the end of 2017, blockchain became the sexiest little underwear. Everyone from all walks of life has one, some wear it on the crotch, some put it on the head, and some put it on a pole as a flag.
Staring at the smart contract code on the screen, I felt a little melancholy. There was no me on the catwalk, and there was no me off the catwalk. I was in an office with insufficient heating, and I was still wearing a down jacket that had nothing to do with sexiness.
This morning, I met Aunt Niu in the community. She pulled me and warned me earnestly, stop writing Java and start working on blockchain. Concept stocks have gone crazy. It was 7 o'clock in the morning, and the temperature was minus 10 degrees Celsius in the community. However, there was an inexplicable smell in the air. It smelled of vitality. It was probably that there was some kind of stimulant in the exhaust gas emitted by the natural gas boiler.
I feel powerless and helpless. This wave of heat has absolutely nothing to do with me. My few lines of smart contract code have made no contribution to the blockchain, an Internet celebrity in 2017. The big guys on the catwalk, again, didn’t ask me to “come with you,” as they always do!
The popularity of blockchain is inexplicable. It seems that just in an instant, the situation a few months ago was completely different. At that time, artificial intelligence was the protagonist, and blockchain was like a daughter-in-law married to a Shandong family, unable to gain publicity. Once at the dinner table, a VC boss (not a big one, not a big one) introduced his investment direction: "It must be artificial intelligence, not blockchain." He stared at me with bright eyes. I lowered my head, a little ashamed. If this was on Weibo, I would kill you. You can look down on me as a person, but you can’t look down on the technology I use, right?
However, just recently, this big guy (not a big one, not a big one) started to read articles about blockchain by Xu Xiaoping and Ma Huateng, and commented: "Profound and good article! Blockchain that changes the world chain!". I don’t know if this big guy (not a big guy, not a big guy) is also going to launch the blockchain brand.
I have always suspected that there is a mysterious "Internet Noun Hype Committee", that is, they are making waves, hyping various concepts in waves... and the VC boss I met (not Very large, semi-large not large), probably not on this committee.
Artificial intelligence VS blockchain, who should win the chicken?
Artificial intelligence and blockchain are the two most popular concepts in recent years.
If you have to compare, who is more powerful, artificial intelligence or blockchain?
When it comes to artificial intelligence, humans tremble, saying they are afraid of being taken over by machines one day. This is a bit like a domestic pet dog. When it sees a fly with a broken wing, it feels like it is facing a powerful enemy. It opens its teeth and claws and jumps up and down, barking. In fact, it is usually too boring and looks for an opportunity to scare itself. Artificial intelligence or artificial intelligence,Be it robots, let alone humans, it’s still too early to take care of a fly. Let’s look a hundred years away. I think that if our country’s GDP ranks first in the galaxy, it will come sooner than artificial intelligence will have self-awareness.
When it comes to blockchain, those who tremble are the centralized authorities, including governments of various countries. This is really not a game of puppies catching flies. Think about it, how much wealth is now hidden in the Bitcoin chain, but governments are powerless, helpless, helpless, and hate it. Flies are also meat. Seeing the flies getting fatter and fatter, the puppies can't catch them and they are worried to death.
So, in the long run, artificial intelligence must be much more powerful. The baton of future technology will be handed over from humans to AI. Isn’t this enough to make AI stinky?
But in the near future, the significance of blockchain is even more significant, because its goal of changing is the human organizational model.
Blockchain eliminates centralized power; Blockchain builds a network of trust; Blockchain uses code to transmit value; Blockchain coordinates dialogue between machines; Blockchain realizes community autonomy. There has never been a savior, nor a fairy emperor - this lyric can be given to the blockchain. In the past thousands of years, the operation of society has relied entirely on the arrangements of centralized authoritarian institutions. Now, finally, there is a glimmer of light on the horizon of technology...
Whatever it is, in the eyes of my Chinese nation , the first question is: can this thing be eaten? The second question is: can this thing make money?
Of course, blockchain cannot be eaten. I don’t need to answer this. Just ask your Guangdong friends. If you want to ask whether artificial intelligence or blockchain is better at making money, I really can’t answer it, and the people of Guangdong don’t know either. This question should be asked to the VC boss (not a big one, half a big one).
When Satoshi Nakamoto was working on “a peer-to-peer electronic cash system”, it was really not for money. Those big guys in the cypherpunk group (really big, no big deal) are all real rebels, and they just want to go against the government! What I pursue is a feeling of freedom. Starting with the three buddies from RSA, as long as they are engaged in cryptography and are not within the US government system, which one is not a thorn in the side of the US government? This is also talking about the U.S. government. If it were any other government, oh my God, the blood would be cold and the grass on the graves would be covered with grass.
There is another wave of big guys (really big, no big deal). They are Mises and Hayek, a group of economists who are deeply hostile to governments of various countries. Hayek believed that the right to issue currency should not be monopolized by the government. The government has no ability to control the issuance of currency, and the issuance of currency should be left to the free market. Letting the government issue currency is like asking rats to cook delicious food. First of all, rats cannot cook at all. Secondly, rats will steal the raw materials. Hayek said: Anyone can issue currency, and multiple currencies should be allowed to compete freely in the market.
Hayek's consistent core idea is that there has never been a savior or a fairy emperor who can formulate and control the rules for economic operation. These rules have evolved unconsciously in the free market.
Leave it to the free market. There are some things that humans cannot understand and cannot operate well.
The core idea of ​​Hayek is also the core idea of ​​artificial intelligence and the core idea of ​​blockchain. Why such a coincidence? Because, awesome people all have the same ideas, while non-awesome people have different ideas.
Artificial intelligence says that this function is too complex for humans to find. Let the machine find many linear functions to fit it. Leave it to the machine.
Blockchain says that trust is something that cannot be trusted by humans. It is better to let machines execute the agreed rules.
Giving power to machines is a common philosophy of artificial intelligence and blockchain.
At this point, we can point out sharply and wisely that artificial intelligence and blockchain actually do the same thing. Blockchain opens the way for machines in terms of organizational form. Artificial intelligence paves the way for machines in terms of capabilities. Human beings' organizational forms and abilities are too old, and it is time to make some changes for the future machine civilization.
For developers, blockchain is easier to get started with. Artificial intelligence is too troublesome. It requires data, a graphics card, and modeling and adjustment to see the effect. Therefore, if you are a poor programmer and want to make a little money, just engage in blockchain. Programmers with dreams and desire to make big money, please go to the right. The artificial intelligence channel is on the right. Please close your eyes and walk in unison, one, two, three, jump!
What can blockchain do?
At this stage, what is the most appropriate use of blockchain? My answer is marketing! In other words, it is most suitable to use it to deceive.
It is said that there are now 5,000 companies across the country related to blockchain. It is also said that there are a total of 200 developers in the country who can develop blockchain.
I don’t think either of these numbers is very reliable. I think a reliable statement is that there are 5,000 CEOs of companies across the country who have read popular science articles about blockchain in their Moments, so their companies are all related to blockchain. As for developers, if they can run Hyperledger, Ethereum, and write a few lines of smart contracts, there must be 5,000 of them in the country.
It is also said that in 2017, the revenue brought by blockchain technology did not exceed 100 million yuan.
So, just listen to the overwhelming propaganda now and don’t take it too seriously. At this stage, this kind of publicity is not a bad thing, and it can be regarded as promoting the development of the industry. With four people carrying the sedan and thousands of people cheering, it can always go a little faster, and the cheerleading team is not without its contribution.
Moreover, the development of blockchain has indeed been promoted. I’ve been asked by 50,000 people: What can I do with blockchain?
After being deceived, everyone began to stare at the centralized systems of their own homes, with doubts in their eyes. Just like when a new season begins, women take stock of their wardrobes.
Actually, there is no need to like the new and dislike the old. What the blockchain wants to get rid of is centralized “organizations”, not centralized “systems”. You can use your OA however you want. There is no need to use blockchain for your own OA system. Just like your family business, it's time to vote for the chairman. Aren't you out of your mind?
To use blockchain, you first need to think about who you want to reach a "consensus" with and on which business? With whom and at what stage are you trying to gain "mutual trust"?
The core is "consensus".
Of course, the blockchain can also be non-stop, which is what Ethereum hypes. But in my opinion, it's really not that important. Once the centralized system is ready, it is almost as close to never shutting down.
Give an example of blockchain application. A common and easy-to-understand example is the scene of signing a contract. When we sign contracts now, we still rely on paper contracts. Sign and seal the paper contract and make it in duplicate, with each party holding one copy. This is a "consensus" that occurs in the real world.
"Paper" and "Signature and Seal" are to prevent tampering. And "two copies" means distributed storage.
If you want to use software to perfectly realize the process of signing a paper contract, that is the blockchain. "Paper signature and seal" is implemented on the blockchain through technologies such as timestamps, hash operations, and asymmetric encryption signatures. "Distributed storage" is completed through POW, POS consensus algorithm and P2P protocol.
The software implementation of the above entire process is the achievement of a blockchain “consensus”.
With the development of IT technology and Internet technology to this day, cash has been replaced by electronic payment, but contracts have always been a big problem, and the paper contract process has always existed stubbornly. Now, blockchain is here to subvert stubborn scenarios like paper contracts.
Let’s give another example. Scenarios of points exchange. I don’t know why, but at the end of 2017, making points suddenly became popular, and every household wanted to make points. I secretly guessed that maybe the King of Chu had a slim waist, and the Holy Will of the King of Chu was cracked by the "Internet Hype Committee". In the early years, our "work points" were just a kind of points.
Of course , Commercial points are very mature in many countries. For enterprises, points are a good customer loyalty management tool, but they have not been implemented in our country. Therefore, it is a good direction to develop commercial points.
The example is this. Two companies, A and B, have issued their own points, let's call them A points and B points. The two companies want to share points so that consumers can use A's points at B and use them at A. B is used thereintegral.
This creates a scenario where a consumer succumbs to company B and uses A’s 1 million points to buy a Porsche. Under a traditional centralized system, company B’s system needs to be connected to A’s through an API. The system verifies the identity of the mouse under the lamp and the number of points. After verification, A's system is requested to consume 1 million A points. With A's consent, A's system records that B has consumed 1 million points. B records in its own database and receives 1 million points from A.
At the end of the month, B took the report of 1 million points and went to A to settle the account. A queries the database and confirms that 1 million points have gone to B. OK, settlement successful.
The question is, what if A does not recognize 1 million points? What to do if you deny it? A What should I do if I change my own database? If it is more complicated and multiple companies participate, B receives A’s points and can also go to C to consume A’s points. How should this be handled?
Blockchain can perfectly solve this problem. Through the alliance chain, the two companies A and B reached a consensus on point transactions in near real-time. There is no need to go through reconciliation procedures at the end of the month. At any time, the blockchain data of A and B are consistent.
Some developers want to get into trouble: I use a traditional centralized system, which can still ensure database consistency.
Of course it is possible. But as long as you do it perfectly and make the databases of A and B completely consistent and solve various possible problems, then in fact, you are developing a blockchain.
Achieving “trust” and “consensus” among multiple parties is where blockchain comes in.
Satoshi Nakamoto designed Bitcoin entirely to design a decentralized electronic currency. From this, blockchain was born.
With Ethereum, the blockchain has transformed into IT infrastructure. Ethereum is the value measure that drives blockchain applications, and smart contracts on Ethereum are the protagonists of the chain.
Theoretically, smart contracts can develop any system. Smart contract in English is Smart Contract, and the “intelligence” here has nothing to do with the Artificial Intelligence of AI. In fact, when Nick Szabo proposed smart contracts in 1995, it had nothing to do with blockchain. Its concept was very simple, which was to write legal provisions into executable code.
But chocolate goes best with rainy days, and smart contracts go best with blockchain. As mentioned above, contracts must be made in two or four copies. Since smart contracts are legal provisions and must be automatically executed, they cannot of course be controlled by one party to the contract. Distributed storage must be implemented to reassure all parties involved. This is the so-called decentralization.
Today, applications using blockchain and smart contracts are mainly concentrated in the following fields:
Financial field: used to make digital currency; used to make payment systems; used to make remittance systems; Used to make clearing systems; used to make securities trading systems; used to make supply chain finance.
Asset description: Used to register assets, such as real estate and land registration, and valuables registration.
Insurance products: used for mutual insurance and other insurance products with simple terms.
Identity authentication: used for personal and corporate identity information storage and online authentication.
Supply chain: used to trace the origin of goods and track the production process.
Government affairs: used for voting; used for official document storage; used for property rights registration.
Of course it can also be used to make games, such as making a blockchain to raise cats, dogs, and frogs, or you can also try raising men?
No matter what you do, before you decide to enter the blockchain, before you decide to start searching for "blockchain", remember my words, you must promote it first, and use it to make the whole world listen. A loud voice shouted: We are doing blockchain.
The current status of blockchain technology
What it can do and how well it does it are two different things.
The most mature applications of blockchain are naturally systems such as Bitcoin and Ethereum. In the field of commercial applications, it can only be said that everyone is still groping.
Many reports say that xx company’s blockchain application is online. In fact, most of them just run a chain in their own homes, or in an alliance of several companies, in their respective laboratories. I haven’t seen any application that releases chain data directly.
At this stage, the application of smart contracts is also used in conjunction with centralized systems. It is rare to implement all business logic on smart contracts.
Most of those who are proficient in using blockchain are entrepreneurial companies. People who can write a chain by themselves probably don't bother to work.
Large-scale, high-capacity applications, such as e-commerce, are almost never implemented using blockchain. After all, at this stage, blockchain still has efficiency and capacity issues. But I think it won’t be too long before it actually comes true. Although it is still "just listen to the sound of the stairs and no one comes down", once someone comes down, the room will be filled with followers.
In less than 10 years, blockchain will become a commonly used technology, just like relational databases today.
But blockchain is destined to be different from relational databases, mobile and big data technologies. It is on the same level as the Internet, or even beyond the concept of the Internet. Because it challenges the human organizational model and changes the human organizational model.
Today’s Internet is so prosperous and has changed human life so drastically, but it has not changed the human organizational model. E-commerce is very developed, but it has only moved the market from community stores and supermarkets to Taobao and Amazon. The bank is still the same bank, and Alipay and WeChat are just another bank.OK; an intermediary is still an intermediary, and a Taobao store is just the online form of a store; if you have to prove that you are your parents' moth, you still have to go to the police station to get a stamp. Nothing has changed, and it is little different from the Ming and Qing Dynasties. Taking "people" as the center to execute judgments and make decisions has remained unchanged for thousands of years.
It’s time to hand over part of the work to machines.
When blockchain technology developed for 50 years, people looked back and were surprised to find that so many institutions had disappeared before they could appreciate the significance of the blockchain in 2107.
In 10 years, blockchain technology will account for one-tenth of the workload in development. This is my estimate. It may not be accurate. I will make a wild guess first, just in case it is accurate.
As mentioned above, smart contracts and blockchain are the best match. Smart contracts are like knights, and blockchain is like a horse.
Blockchain also has a perfect match, and that is the Internet of Things. How should we do the interconnection of all things, the dialogue between things, and the transactions between things? It is perfect to use the decentralized storage of blockchain and the consensus algorithm of blockchain. However, that is still far away. When blockchain is combined with the Internet of Things, my country’s GDP will definitely already be the first in the solar system.
How should I apply blockchain
As mentioned above, the first thing to do when using blockchain is to make a loud noise and let the whole world know that you are using blockchain. Do your own marketing, and on the other hand, promote the development of the industry.
The second thing is to look at your own business and see where you need to reach consensus and mutual trust with others. Once you find it, that’s where you use blockchain.
But remember, you must be cautious when applying blockchain today. This is still very different from developing systems with relational databases and JAVA.
You must analyze and design carefully before taking action. Which open source blockchain to use, whether it should be deployed on a public chain or a private chain, how to design the smart contract, how to interface with the centralized system, how to run it after it goes online, and how to maintain it, all these must be carefully considered.
In fact, there are only a few technical routes that can be chosen, such as Bitcoin, Ethereum, Hyperledger, and Quorum. There are not many options.
You can also find domestic blockchain companies and use their chains directly. Some companies’ chains are also very reliable. Many companies such as Qulian and Bubi are serious about making chains. However, as far as I know, domestic chains are all modified from those international chains.
If you want to do it yourself, find two engineers with strong research capabilities and learn Ethereum or Hyperledger from scratch. In about two or three months, you should be able to write smart contracts and make Dapps. If you still can’t , just fire them and recruit two more. If you are ambitious and want to modify the chain protocol yourself, it will be more difficult to start from the source code. You will have to find a few Ph.D.s who are good at mathematics and proficient in algorithms and work hard for a year or two. actually, changing the chain source code is also a conscientious job. If you change more or less, as long as you don't release it, only you will know.
Before taking action, it is best to find someone who has done blockchain projects and consult with them. Maybe a word from someone can save you 3 months of effort. You know, on the vast Internet, there is really no mature application solution for blockchain, and everyone is groping for it.
The biggest challenge is: how to use blockchain technology to implement my application scenarios.
Everyone is groping in the dark, and the only way to succeed is to turn on a light. When thousands of lights light up and the room is brightly lit, blockchain technology will no longer be uncommon.
What I’m afraid of is that after touching it, the light will be in vain. If I just touch the fluttering leg hair, but can’t touch the light, everyone will become discouraged, disperse, and stop touching. The artificial intelligence has been scattered several times. In recent years, it has regained its confidence and continued to explore. The leg hair of the big guys once again shined in the dark.
What can I get from using blockchain
For engineers, if they master blockchain technology, of course their salary will increase. Blockchain talents are still very scarce today.
For a company, if it uses blockchain, don’t just watch the blocks being mined out and have fun on your own. It must be promoted widely. The brand will be improved, sales will increase, and the stock price will increase. Market value will skyrocket.
In the final analysis, stock price and market value have little to do with blockchain technology. They have risen because of the good deception technology. Those big guys, that is, the members of the "Internet Terminology Hype Committee", if they don't speculate on blockchain, they will speculate on AI, and if they don't speculate on AI, they will speculate on iOT. In short, there will be no shortage of ingredients in their frying pans. of. How to cheat, how to get money, money is falling from the sky.
I really like blockchain technology, and I don’t have a godfather in the “Internet Hype Committee”, so don’t think too much about it. Diaosi should avoid being greedy. Don't think about money. Use it first and then talk about it. You can get a taste of it even if you don't get any discount.
In 2013, in a small office in Wangjing, I chatted with several friends and talked about using Java FX to build a Bitcoin trading website. A friend said: "Bitcoins are going crazy right now. They cost more than 200 yuan each. It's good to be an exchange."
I liked Bitcoin at that time because of its anti-thief temperament, but I didn't purchase. Neither did the exchange.
Now I regret it, but not just because I missed the profit opportunity of Bitcoin’s rise. But I reflected and came to a conclusion, that is, although I kept saying that I loved freedom, in fact, it was just Mr. Ye who liked dragons. When a utopia of freedom was placed in front of me, I did not cherish it and did not dare to walk into it. I didn't buy Bitcoin, which is a good example.
