Ⅰ What is the development trend of blockchain, and what is the development trend of blockchain technology?

The development trends of blockchain are:
01. Blockchain industry Long-term improvement, core values ​​are generally recognized;
02. Technology development is more pragmatic, with engineering and ecological construction becoming the focus;
03. Blockchain and privacy computing develop collaboratively;
04. Blockchain interconnection has become the focus, and the future of value interconnection is promising;
05. The call for blockchain infrastructure is gradually rising, and the construction model still needs to be explored in depth;
06. Blockchain cannot conquer the world; Cooperate with multiple technologies to complete digital transformation;
07. The application of certificate storage takes the lead, and gradually moves towards multi-party collaboration and value transfer;
08. The importance of the blockchain alliance business model is further highlighted;
09 , Government support will still be an important driving force for industrial development in the future;
10. As the scale of blockchain practitioners increases, the relative shortage of talents will continue to exist.

(1) Blockchain and software crisis Extended reading:
Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. thing. Compared with traditional networks, blockchain has two core characteristics: first, data is difficult to tamper with, and second, it is decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.
Blockchain is still mainly used for certificate storage. For example, the application of blockchain in supply chain finance, product traceability, trade finance and other fields has achieved certain results, but its application model is still based on documents, contracts, The main thing is the deposit certificate of the bill. As the industry application of blockchain continues to deepen, in order to further promote the role of blockchain in promoting the development of the real economy, in the future, we will focus on the development of multi-party collaboration and value transfer applications.
Blockchain is not just a technology, but also a concept and a cooperation model. Blockchain will connect upstream and downstream parties in the industry, and it is necessary to rely on the common interests of the alliance to bring together all participants. At present, there are two main organizational models of blockchain alliances, namely core organization leadership and participating organizations co-governance. Both blockchain alliance business models also have their own pros and cons. For the long-term and stable development of the alliance, how to build and which kind to build The model also requires continued in-depth exploration by the industry.

Ⅱ The development of blockchain has been frustrated during the epidemic, and the flashy blockchainChain pilots are falling out of favor

Amid the COVID-19 pandemic, blockchain vendors and advocates fear enterprise frustration with blockchain implementations.

The adoption of blockchain is a relatively new area for business leaders. As the economy shrinks and IT budgets shrink, blockchain may be the first project to be axed.

While no sweeping changes have hit blockchain adoption, the landscape of the technology has certainly shifted.

Similar to the trends in data and software, the focus of blockchain implementation in the COVID-19 era has also shifted to areas where technology can provide the greatest value in the shortest time.

Eschewing flashy pilots without clear intent, leaders are targeting areas of higher value, with COVID-19 pressures further deepening the weaknesses of existing blockchain applications.

In the aftermath of the crisis, funding for blockchain pilots has slowed as bosses suspended forward-looking projects and spent funds on more urgent firefighting activities.

According to forecasts released by IDC in June, as global IT budgets shrink, global blockchain spending is expected to reach US$4.3 billion in 2020, a year-on-year increase of 57.7% from US$2.7 billion in 2019. . Despite this growth forecast, it is down 7.7% from IDC's last forecast.

Global blockchain budgets are currently forecast to reach $14.4 billion by 2023, a further reduction from the pre-COVID-19 estimate of nearly $16 billion.

The current actual impact on blockchain adoption has been low. One trend has been a decline in interest among large companies in pilots and proof-of-concepts without clear commercial returns.

When assessing the shift in blockchain adoption post-COVID-19, a crucial context is the instability of the economic environment.

When the first wave of lockdowns hit North America and Europe, almost all blockchain work was initially halted except for networks already in production.

Some large vendors and software integration companies have shifted their focus to enabling remote work, with people almost all working from home.

When considering blockchain implementation, enterprise technology leaders must always be wary of the hype from vendors and technology proponents and think carefully.

According to Gartner data, as of 2019, only 4% of organizations have blockchain projects and are running them on a large scale.

In the current environment, where IT leaders are under pressure to shrink budgets, any blockchain project that does not have a very clear reason for existing risks being shut down.

As companies evaluate the merits of blockchain pilots, clearBenefit criteria include:

But for the implementation of blockchain, as an integral part of the platform, it can improve the supply chain and reduce costs.

Delivering these benefits has proven elusive for most businesses. According to Gartner, even those networks that exist today will need to be replaced as technology evolves to remain competitive, secure and avoid obsolescence.

As enterprises adapt to new operating environments, blockchain offers a way for enterprises to reduce the cost of reliable access to data between partners and reserve non-value-added costs.

To effectively pursue blockchain as part of their digital transformation journey, CIOs need to determine which aspects of their business and operating models can be automated to better serve customers.

Organizations should evaluate which combination of solutions can help achieve this outcome. In this case, blockchain can be connected with artificial intelligence or the Internet of Things. Instead of looking at blockchain as one thing that provides multiple capabilities, try to see the different capabilities of blockchain and try to integrate them into your business needs.

Ⅲ Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralization A distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases. It makes transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly Payment transactions are carried out without the involvement of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
1.1 What is Blockchain
Blockchain (BlockChain) refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate through a series of data blocks (blocks) generated using cryptographic methods. Each data block containsContains all information exchange data of the system within a certain period of time, and generates data fingerprints to verify the validity of its information and link (chain) to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger. Therefore, this data becomes very safe. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress - people cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, the legal currencies of various countries, the credit values ​​are different, and the clearing systems are also incompatible, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

Question 2: What is blockchain? What does it mean in layman’s terms? What is China’s attitude towards blockchain? What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. One of the most basic characteristics of Bitcoin is decentralization. In recent months, financial giants have gradually begun to pay attention to Bitcoin's technology and used it in non-monetary fields, such as stock trading, election voting, etc. (1) Art Industry
Artists can use blockchain technology to declare ownership and issue numberable, 100% edition works in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
(2), Real estate industry
Use blockchain technology to solve various problems faced by everyone involved in real estate, including the naming process, land registration, agency intermediaries, etc.
(3), Insurance Industry
The financial industry has always been the most sensitive to advanced technology. Traditional banking and securities industry giants have been involved in the booming blockchain venture capital investment since 2014, with total global investment reaching US$1 billion within two years.
(4) P2P wallet
Personal assets can be traded through this P2P wallet in the future without going through any central institution, such as Bitcoin.
Most blockchains are in their infancy, mainly overseas. There are very few good domestic blockchain projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and other applicationsUse, Internet of Things, etc.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.
A simple understanding of blockchain is a technology at the bottom of Bitcoin, which is also a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between Bitcoin, Bitcoin blockchain, blockchain and blockchain. Blockchain technology and other concepts. In countries with relatively developed finance in the past, finance and blockchain technology have a long history, and the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various equity, supply chain, points and other fields. Major domestic financial institutions and enterprises have taken a fancy to the new industry. value, they have developed their own blockchain platforms, and blockchain has instantly become a new innovative industry in China. In terms of overseas internationalization, the United States has already obtained 15 blockchain patents at the end of last year compared to China. Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will also become more and more profound. It has attracted more and more attention and will form a huge new trend... >>

Question 3: What is blockchain technology? What exactly is blockchain? What is blockchain? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through the data block, we can query each transaction record. A look at the history of Bitcoin transactions. 2. Example: There are three persons A, B, and C. All funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then: A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan in A's name, and add 80,000 yuan in B's name.Add 80,000 yuan. If B transfers 50,000 yuan to A, C will add 50,000 yuan to A's name and subtract 50,000 yuan to B's name in the account book. A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name. 3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the network. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the network form Bitcoin’s distributed network database system. 4. The essence of data blockchain technology is a decentralized and distributed structure of data storage, transmission and certification methods. It uses data blocks to replace the current Internet's dependence on central servers, so that all data changes or transaction items are recorded. On a cloud system, the self-certification of data during data transmission is theoretically realized. In a far-reaching sense, this transcends the traditional and conventional information verification paradigm that relies on a center and reduces the cost of establishing global "credit." This point-to-point verification will produce a "basic protocol", which is a new form of distributed artificial intelligence and will establish a new interface and shared interface between human brain intelligence and machine intelligence.

Question 4: What is blockchain: This explanation of blockchain is more understandable. Blockchain refers to a technology that collectively maintains a reliable database through decentralization and trustlessness. plan.
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain technology has become the darling of the financial community in China and has become a hot topic. Domestic Puyin Group has launched Puyin, a tea-based digital currency.

Question 5: Explain in an easy-to-understand manner what blockchain is. Blockchain can be understood as a database system in a sense. The development of blockchain can be divided into 1.0 and 2.0
1.0 is divided intoBitcoin is the representative, and its main application is virtual currency or digital currency application. The blockchain at this time can only be used for simple digital currency transactions.
2.0 is represented by the now popular ethereum (Ethereum) and the upcoming hyperledger. The blockchain at this stage can not only meet the corresponding digital currency transactions, but also use smart contracts to customize currency or asset transactions. If we use the database analogy, the emergence of smart contracts can be understood as allowing users to define functions or stored procedures in the database and call and execute them.
Different from traditional databases, the blockchain introduces consensus mechanism, incentive mechanism, p2p (network), hash and other specific elements, making it open, decentralized and non-tamperable. characteristic.

Question 6: What is blockchain? Can anyone explain it in simple terms? Blockchain is the underlying technology of Bitcoin. It is like a ledger that records all transactions. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay in Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. Without it, it means decentralization, just like buying things offline. If you pay with one hand and get the goods with the other hand, there is no third party.
The blockchain itself is a series of cryptographically related data blocks generated.
Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.
Many companies are developing this technology, including ours, and its prospects are incredible. For details, you can go to our official website and hope to adopt it, thank you

Question 7: What is blockchain technology? What is blockchain? How to explain the concept of blockchain? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
In the past six months, the concept of blockchain has gradually become popular in China, and a blockchain whirlwind has taken off in the financial circle. Blockchain has attracted the attention and favor of more and more people in the industry due to its unique technical advantages. Blockchain technology, which is decentralized (or multi-centered), highly transparent, cannot be tampered with, and has no single point of failure, is entering the field of vision of financial institutions and enterprises. It has at least been used in digital currency, payment exchange, registration and settlement, Digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussions to practical applications.
"Blockchain" was first introduced with "Bitcoin" released in early 2009. Blockchain has become the basic protocol and technical application for the launch, recording, and circulation of Bitcoin. Although bitBitcoin has been controversial since its inception, and it cannot even be regarded as a "currency" by governments and monetary authorities. However, the blockchain technology used in Bitcoin has received widespread attention, including from governments and monetary authorities. .
Why has blockchain become a rapidly heating up 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 relationship with traditional society ( 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 connection with offline) and are fully applied in the online world (online), provide people with the opportunity to adapt to the Internet society. Development provides alternative paths and unlimited imagination.
Judging from its application in Bitcoin, blockchain is a set of new network blocks (BLOCK, also called communities) formed by combining encryption technology with the Internet. Bitcoin configuration, netizen identity verification, and Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (added block and transaction time identification, etc. Internet protocol rules and accounting (Ledger) system including block chain, full encryption, mutual authentication, etc., including factor) registration and verification. Precisely because Bitcoin is not a substitute for offline legal currency, but is issued and managed by non-legal currency authorities, mainly imitating the model of gold, and is completely new and decentralized protected and supported by basic Internet protocols and strict encryption technology. Internet currency (virtual currency) has thus formed a new set of currency rules and systems that are different from and not subject to real social laws, and can be bought, sold or exchanged with legal currency. It has been more than 8 years since Bitcoin was launched. There has been no record of funds or user information being stolen. Its security has been verified, and its efficiency and cost of fund settlement also have obvious advantages. This has made people's confidence in the blockchain technology used in Bitcoin continue to increase, and people have become more and more aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, the blockchain Chain is not the same as Bitcoin, and its application is by no means limited to Bitcoin. The application of blockchain can be decentralized or centralized; it can be a public chain model or a private chain model. Therefore, after Bitcoin, blockchain technology is also constantly developing and innovating, and constantly exploring new application fields, especially in the financial field.
The reason why blockchain is valued highly by more and more people is because the development and widespread application of the Internet have caused more and more economic exchanges and transaction activities to be conducted online, and the online world (or online world) society) is rapidly expanding, enriching and active, and online transactions must solve the efficiency and security protection issues of the parties' identity verification, value verification, transaction records, inspection and verification, etc., and require strict intermediaries and protocols(Rules or Constitution). In this regard, traditional thinking and customary practices are to follow the development trajectory of the transfer of offline transactions to online and push the common rules and practices of the real (offline) society to the online (network) society. However, in practice, it is increasingly It is difficult to adapt to the needs of online transactions.
For example, for the identity verification of the parties, the natural choice is to use the information on the identity documents protected by the laws of various countries as the basis, and then add account or transaction passwords, as well as facial recognition, iris, fingerprints and other biometrics to conduct online transactions. Verification, but this method first makes the citizen identity information in the cross-border interconnected online world subject to the administrative jurisdiction of real society... >>

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology to encrypt and decrypt so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has launched the digital currency crowdfunding platform Biying China.

Question 9: What is the so-called "blockchain"? Blockchain itself is a tool called decentralization and trustlessness. For example, when you graduate from university, the current practice is to have a certificate recognized and issued by an authoritative agency as your certificate. This setting is more troublesome, because this is a piece of paper, and paper can be forged, so there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, whoever There are various possibilities related to media. The blockchain provides a great opportunity. As soon as you graduate, you will have a record on the blockchain. No one can change this record. This thing exists objectively. You, as a physical existence , and then as a data existence, the blockchain was born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is different from the usual social networking (WeChat) and payment platforms (Alipay, Yibao)Big data that is often involved has similar places.

Question 10: What does blockchain mean? Regarding blockchain, I think you have already seen the concept on the Internet. Let me explain it based on my understanding!
First, let’s talk about its characteristics: 1. Openness and transparency 2. Decentralization 3. Anonymity 4. Information cannot be tampered with, eliminated 5. No trust cost
Blockchain is like a public ledger , everyone has the right to record and read, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be permanently saved, and can only be added but not deleted! However, as the number of blocks continues to increase, costs will increase and efficiency will decrease. (I’m not sure whether technology can be used to make up for this. I hope someone who understands technology can point it out.)
Blockchain is divided into public chain, private chain, and alliance chain. Public chain: accessible to everyone, everyone has read and write permissions, completely open, transparent and decentralized. Private chain: Open to individuals or institutions, in which the owner of the private chain can set various permissions to make it partially centralized. Alliance chain: Open to specific organizations or groups, it is also "partially decentralized". According to the ledger at the beginning, members can view and transact, but cannot record and confirm bills, or require permission from the alliance. (The latter two do not have cost and efficiency issues)
Regarding blockchain, countries have begun to recruit talents in this area. For this, you can search online for "Central Bank Recruiting Digital Currency R&D Personnel". In addition, you can increase your understanding of blockchain by understanding its existing applications. What we usually refer to generally refers to public chains. Currently, those used abroad include Bitcoin, Ethereum and other domestic blockchains. Chain
1. Open and transparent: Every piece of data is verified by everyone and can be viewed by everyone at any time.
2. Decentralization: For example, when we shop on Taobao, we conduct transactions through the intermediary Taobao, and blockchain allows both supply and demand parties to directly contact each other for direct transactions through blockchain technology.
3. Anonymity: No personal privacy information is required to complete transactions on the blockchain, only your unique alphanumeric signature is required.
4. Information cannot be tampered with or deleted: Once the data has been verified and recorded, no one has the authority to modify it, let alone delete it!
5. No trust cost: The trust crisis in reality will not appear in the blockchain. Transactions in the blockchain do not require you to trust the other party. Only when both of you have enough "digital assets" to trade can it be carried out, and Under the supervision of the entire network, transactions will not be broken. If you have no idea about the cost of trust, just think about how many intermediaries there are in your city, or just think about Jack Ma, and you will know how big the cost of trust is.
I am still learning more about blockchain. I am Li Ailin. If you have any questions, you can discuss and learn together!

IV The United States officially launches 6G experiment to test the top ten future technology trends.Break through your imagination

When 5G was not yet mature, the United States tried to skip 5G and directly deploy 6G, which attracted widespread attention around the world.

After Trump approved the US 6G experiment, the US Federal Communications Commission officially launched the research and development of 6G technology.

In addition, more than 30 universities are cooperating in research and development of 6G-related projects, and financial companies are also providing financial support.

Once 6G technology matures, remote holographic technology, driverless driving, smart robots and other fields will accelerate development.

Technology is developing at a speed beyond imagination.

The ten major trends in technology in the future will gradually become mainstream, changing our lifestyles and even ways of thinking.

70% of urban population and upgraded smart cities

There are reports predicting that by In 2045, nearly 70% of the world's population will live in cities.

With the acceleration of urbanization, a large number of people are pouring into cities, which puts forward the requirements for urban infrastructure construction, such as power energy, sewage treatment, intercity transportation, etc. higher requirements.

Future smart cities will use big data and automation to improve operational efficiency and achieve sustainable development.

Stagnant cities may become overcrowded and dirty "garbage dumps".

Big data "dark horse" with endless potential

At present, the data created by humans The volume has exceeded 10 billion TB.

Although the amount of data is huge, only 10% of the data is analyzed every year.

People’s consumption habits, health status, and other social public data are hidden in the huge ocean of information on the Internet middle. These data play an important role in obtaining information, predicting behavior, and accurately reaching people.

In the future, there will be further breakthroughs in both data acquisition and data analysis and application capabilities. Details such as our walking posture and speaking voice may be collected for business, regulatory and other decision-making.

New technologies will rebuild the trust ecosystem

Technology is a double-edged sword.

It gives us the ability to correct and improve pictures and videos, but it also allows for endless video fraud, picture fraud and other incidents.

Researchers at MIT were once able to extract images and postures of human movements, and after training with AI, synthesize new postures and generate new video.

This is just the tip of the iceberg of technological fraud.

The trust crisis needs to be resolved urgently. All sectors of society will be committed to the development of new technologies, strengthen intelligent identification and falsification capabilities, and try to rebuild the trust ecosystem in the technology era.

Fragile privacy and the “right to be forgotten”

We can’t really delete Our past.

Privacy in the digital age is more fragile than ever.

The European Union issued a document in 2010, the core of which is the "right to be forgotten", emphasizing people's right to know about personal data services and the deletion of personal data. Data Rights.

However, most ISPs are unable to fully comply. The so-called "cancellation" cannot erase the residue of personal information. Data security and privacy issues will become new technical hot spots.

Synthetic biotechnology: rewriting life

As we enter a new era of biotechnology, every life is information that can be rewritten.

Since Mendel discovered the laws of inheritance, humans have begun to explore plant and animal genes. With the further development of genetics, we can change the genetic characteristics of organisms by building new DNA.

In the future, genetic modification and gene editing will be at the forefront of the era of biotechnology, creating products that can benefit human beings. Biological plants used.

However, the public acceptance and ethical issues of synthetic biology still need to beConsider.

The Internet of Things: Pushing the Boundaries

In 2045, conservative estimates will see more than 1,000 Billions of devices are connected to the internet.

The new generation of IoT platforms will break through the boundaries of cloud computing, enhance insights into time and space, and integrate with smart cities, energy, medical care, electricity and other scenarios , complete the automation of a large amount of work, improve the efficiency of production operations, and generate huge value.

Information from the Internet of Things will help us further understand and control our lives.

The cooperation of the three major technologies of the Internet of Things, big data, and artificial intelligence will create a huge intelligent network.

Blockchain: From virtual to pragmatic

Blockchain did not explode overnight It is not a tool for wealth, but the infrastructure of the future digital economy.

Blockchain technology will innovatively integrate with all walks of life, establish peer-to-peer trust and a new management system, and pragmatically solve the economic and people's livelihood problems. and other issues, benefiting all walks of life.

After the bubble, the development of virtualized blockchain will become closer to the physical world, and diversified innovative blockchain applications are expected to enter the homes of ordinary people.

Quantum computing: a new round of explosion

In 2021, quantum computing will usher in Here comes a new outbreak.

In recent years, research on quantum computing has begun to show results, and this profound concept has gradually entered the public eye.

Nowadays, many technical barriers to quantum computers are being broken down one by one. In the future, we are expected to create a true quantum computer.

Quantum computing will initially form an ecological industry chain, and high-quality quantum computing platforms and software will emerge in large numbers and receive attention in more fields. When quantum computing is integrated into AI and cloud computing, it will take on a completely new look.

Human Augmentation Technology: Pushing the Limits of Potential

Human augmentation technologyIt will lead to the ultimate limit of human potential.

Human augmentation technology is mainly divided into three areas. One is wearable devices that transmit real-time information to the senses, and the other is exoskeletons and prosthetics connected to the brain. , The third is to enhance some abilities through drugs.

The elderly, weak, sick and disabled will benefit from human augmentation technology, but the high price may be prohibitive.

The hidden danger is that our bodies and brains with devices are likely to be attacked by hackers.

Robots: everywhere

Sweeping robots, welcome robots, supermarket robots …Robots are appearing more and more frequently in our daily lives. In the future, robots and automated systems will be everywhere.

As the sensitivity and mobility of robots improve, they will undertake a large number of tasks in daily life and replace part of human labor.

However, the "laid-off wave" and ethical issues caused by the widespread application of robots will also bring disputes and challenges to society.

IV After experiencing explosions and disillusionment, can blockchain games still be reborn?

Blockchain games can still be reborn. After all, everyone is in great demand for them now. It is big, and this area has been studied in depth. It has not been abandoned, and there is still hope for the future.

Many blockchain practitioners have high hopes for blockchain games and believe that it is one of the best means to promote blockchain technology. However, due to limitations of technology, funds, user preferences and other reasons, most of the first batch of blockchain games have been reduced to drumming, flower-passing scams and fund disk carriers. A year later, more and more practitioners are trying to change this situation, but they still face many problems and challenges.

After experiencing explosions, disillusionment and rebirth, the future of blockchain games is still full of hope. So blockchain links will usher in a new beginning.

VI Re-understanding the blockchain: Enlightenments brought by more than 1550 application cases

Author: Ran Wei

(This article is excerpted from the "2021 Global Blockchain Application Market Report")

When we talk about blockchain, as long as there is something about blockchain Anyone who understands can express some of their own opinions on related topics to a greater or lesser extent. For example: from the perspective of technical system, blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm; from the perspective of functional attributes, blockchain is decentralized, non-tamperable, and full-process. Features such as leaving traces, traceability, collective maintenance, openness and transparency.

Looking back at the history of blockchain, there is no way around Bitcoin. On January 3, 2009, the Bitcoin genesis block with serial number 0 was born. A few days later, on January 9, 2009, Bitcoin block number 1 was born. When two blocks are connected, the blockchain is "born."

The inventor of Bitcoin, whose pseudonym is “Satoshi Nakamoto”, may find it difficult to imagine: In the past 12 years, with Bitcoin as the center, a huge “cryptocurrency family” has spread all over the world. The financial market set off a "big wave" that continues to this day. During this period, innovation and risks related to cryptocurrency are intertwined, progress and bubbles coexist, and pursuit and criticism coexist, and it drives government departments of various countries to continuously improve the monetary and financial systems, social governance and supervision systems.

At the same time, the blockchain that accompanies Bitcoin is also evolving rapidly, and has long gone beyond the scope of "Bitcoin's underlying technology" and has been applied to every corner of social and economic development.

So, what mechanism does blockchain work through? What are its advantages compared to traditional technologies and models? What is its application effect? In the "2021 Global Blockchain Application Market Report" jointly released by Capital Lab and Yuanwang Think Tank, we tried to provide a certain basis for the above issues through research on more than 1,550 application cases around the world in 2020 and the first quarter of 2021. Empirical answer. At the same time, based on the study of these cases, we can establish a new understanding of blockchain: blockchain is trust, blockchain is sharing, blockchain is transaction, blockchain is substitution, and blockchain is efficiency.

In the Bitcoin creation paper "Bitcoin: A Peer-to-Peer Electronic Currency System", "Satoshi Nakamoto" repeatedly emphasized that Bitcoin has the characteristics of not relying on a "trusted third party". That is the characteristic of “decentralization”.

On the other hand, the underlying technology of Bitcoin, the blockchain, is precisely designed for "trust." In other words, reshaping "trust" in the digital age is the most basic function of the blockchain, but this trust has been transformed from trust between people and legal entities to trust between machines and machines. Trust between blocks and between nodes. What’s interesting is that the subsequent “wisdom” products that were bornThe "energy contract" function further strengthens this trust through the integration with the blockchain.

Identity coding and authentication are the first steps to achieve the above-mentioned trust mechanism. Distributed Identity (DID) ) system is the core of it. With DID applications, everyone from individuals to organizations to IoT devices, from physical items to virtual products, can be given digital "identities" and achieve trusted interactions. Because of this, Only then can certificate deposit, empowerment, verification, circulation, and transactions be realized based on blockchain, and only then can blockchain be implemented in various industries.

Application cases from around the world show that new The trust mechanism provides new rules and motivation for social and economic operations:

l China is comprehensively promoting the application of blockchain electronic certificates, allowing enterprises and residents to enjoy more efficient and convenient government services;

l "One fish, one code", "One fruit, one code", "One tea, one code" and other applications are promoting the upgrading of global agricultural product anti-counterfeiting traceability and food safety systems;

l Through the combination of blockchain, big data and artificial intelligence, the credit "portrait" of an enterprise is more accurate, and it can obtain faster and lower-cost financing services;

l Charity organizations have put donations on the chain to form a more transparent and standardized charity tracking and management system;

l Relevant cities in China have launched a blockchain-based gas cylinder product traceability management system , the credibility of the source of gas cylinder file information and the level of gas cylinder safety management have been greatly improved;

l Germany is establishing a digital registration system based on identity authentication for its distributed energy assets to promote the development of renewable energy and transactions, and cope with the arrival of the digital energy era...

Among the three types of blockchains (public chain, alliance chain, private chain), alliance chain has been the most widely used. In addition to considerations of technical performance, operational efficiency, operability, expected results, etc., this is mainly because all parties in the alliance already have a certain foundation of trust. This also shows from another perspective: in areas beyond cryptocurrencies such as Bitcoin, In blockchain applications, "multi-centralization" rather than complete "decentralization" is a more realistic choice.

In addition, it is undeniable that: unlike Bitcoin "mining" The proof-of-work mechanism on which the "mine" relies, the blockchain cannot completely ensure the authenticity of the on-chain data from the source in the actual application process. In other words, a certain alliance member or node may provide false data intentionally or unintentionally . However, with the help of the blockchain's non-tampering, traceability, multi-party consensus and other characteristics, the alliance can identify counterfeiting behavior and make corresponding punishments, such as "kicking" the counterfeiting members from the node. Therefore, in a sense, Based on blockchainTo a large extent, trust is established by alliance members to have awe of the authenticity of data and to be deterred from data fraud.

If "trust" is the foundation of blockchain applications, data sharing is the core of blockchain applications. Without data sharing, there will be no cooperation, and the practical application of blockchain will be impossible.

l The State Administration of Foreign Exchange's "Cross-border Financial Blockchain Service Platform" pilot has been fully launched, promoting foreign trade exports through information exchange between foreign exchange bureaus, taxation, banks and enterprise-related market entities. Business development;

l The "Insurance/Claims Alliance Chain" jointly established by 11 insurance companies in Taiwan has been put into operation, and each company has achieved "single application and common documents" on this platform;

l Blockchain platforms such as Contour and TradeLens are reshaping the global supply chain and providing impetus for the digital transformation of international trade through data collaboration among enterprises, financial institutions, shipping companies, terminals, customs and other institutions... .

l In China, through data collaboration, various government departments have realized "one data, one source, one source for multiple uses, one network, and full network operation";

l Through The "Judicial Chain" platform allows all types of electronic evidence to be seamlessly connected with judicial institutions such as notarization, arbitration, judicial appraisal, and courts, which improves the efficiency of the judicial system while reducing costs;

l Targeting grassroots nationwide The court's "cross-domain collaboration mechanism for trial auxiliary matters" can realize "cross-domain service and cross-domain evidence collection" between courts in different regions, effectively improving the efficiency of trial auxiliary matters and trial quality and efficiency, and reducing judicial operation costs... ….

l China's "Guangdong-Hong Kong-Macao Greater Bay Area Combination Port" project was officially launched, which can support the interconnection and interoperability of trade parties among the five major customs jurisdictions of the Greater Bay Area and become the first connected port in the Greater Bay Area , customs, logistics, enterprise, finance and other trade processes, interconnected and shared blockchain network;

l Japan's KDDI Telecom, Hitachi, Kansai Electric Power, Sekisui Construction and other large enterprises have established blocks Chain Alliance NEXCHAIN ​​to form a cross-industry real estate information sharing and management model and promote cross-industry innovation;

l The French Renault Group completed the test of its blockchain project "XCEED" for zero Sharing compliance information between component suppliers and automakers and simplifying compliance certification….

Although the above application cases in finance, government affairs and various industries are only a few typical cases, they are enough to illustrate that: on the one hand, data sharing is an inherent requirement of blockchain applications. In terms of specific implementation, everything must start from breaking "data islands" and "information asymmetry"; on the other hand, the application practice of blockchain has in turn promoted cross-level and cross-departmentdoor, cross-industry, cross-region, cross-border data sharing and unprecedented cooperation.

It can also be seen from the above cases that based on the transparency, security, trustworthiness and other characteristics of the blockchain, data sharing allows cooperation that originally seemed impossible to be achieved, and more Open innovation results; data sharing can effectively improve the operating efficiency of business systems, financial systems and social governance systems; various organizations promote their own organizational changes and process changes while sharing and cooperating with external institutions.

Based on trust and sharing, "transaction" is the most intuitive and deepest manifestation of the value of blockchain applications. Currently, blockchain is opening a new chapter in the transformation of transaction models in various industries around the world.

From the perspective of functional architecture, blockchain-based transactions are by no means just a change in the transaction process. Instead, they integrate various unique functions of the blockchain. Integrated integration of blockchain applications such as logistics, payment/settlement, supply chain financing, insurance, and network security.

From the perspective of application form, blockchain-based transactions transcend the traditional concept of product or service transactions and represent the realization of the value of a wider range of data in circulation.

From the perspective of application scenarios, transactions based on blockchain involve the upgrading of the physical industry, the digital advancement of the financial industry, and the innovative application of the "token economy".

In the physical industry, take the application of agricultural blockchain as an example: on the one hand, supply chain traceability based on blockchain has become an important barrier to food safety; but on the other hand, for growers or For farmers, the supply chain traceability function is far from enough. How to help them expand the sales of agricultural products and obtain more income as much as possible is the "hard truth" for blockchain technology to continue to promote agricultural development. In other industries, the same applies.

Against the above background, new trading platforms in the global physical industry continue to emerge:

l The Indian government uses blockchain platforms to help farmers in remote areas sell agricultural products to reduce the While eliminating intermediate fees, obtain higher income;

l The Swiss company Cerealia builds a blockchain-based agricultural product trading and financing platform to promote the export of agricultural products in emerging market countries around the world;

l The world's largest independent refined sugar producer, Al Khaleej Sugar Company of the United Arab Emirates, launched DigitalSugar.io, a blockchain-based sugar product trading platform, to realize spot-based international raw sugar trading;

l Ganzhou, Jiangxi Province, has launched an international timber electronic trading platform based on blockchain to manage the entire timber transaction process on-chain, and will provide the timber market with full industry chain services such as cloud warehouse supervision, logistics, finance, and insurance;

l Shandong Province has launched the Shandong Internet Traditional Chinese Medicine Trading Platform, which will realize online integrated services of quality control, trading, payment, settlement and supervision through blockchain and other technologies;

l Weitang Town, Xiangcheng District, Suzhou has released a blockchain-based pearl online trading platform, which will add core parameters and test reports of pearls to the chain for certification. It will also add supply chain management, trade finance, smart contracts, payment settlement, and incentive mechanisms. and other functions;

l Honeywell launched GoDirect Trade, an online trading platform for new and second-hand aircraft parts, providing guidance for large manufacturers on how to apply blockchain to parts trading and circulation. A valuable reference….

In the financial industry, blockchain is promoting the digital advancement of financial transaction business in aspects such as securities trading, asset securitization, trade financing, and cross-border settlement:

l The Australian National Stock Exchange has launched ClearPay, a digital securities trading platform based on distributed ledger technology, which can provide multi-currency, real-time DVP settlement on the same day and will replace the original exchange settlement system;

l Switzerland The company Finka has launched a related securitization token investment platform based on livestock from organic pastures in Bolivia to promote the development of the local livestock industry;

l The American company Securitize has established a Japanese real estate investment platform based on digital securities , aiming to revitalize idle real estate in rural Japan and enhance the vitality of the rural economy;

l China Postal Savings Bank and China Construction Bank completed the first cross-blockchain platform forfaiting transaction, Hua Xia Bank Kunming Branch’s first Realize forfaiting resale business in the secondary market;

l Nanjing Iron and Steel completed blockchain-based iron ore transactions with Rio Tinto of Australia and Vale of Brazil respectively;
< br /> l Baosteel Co., Ltd. and Australia's Rio Tinto completed the first blockchain-based RMB cross-border settlement transaction...

Of course, while blockchain promotes the advancement of financial transaction business, dark sides such as hype, scams, money laundering, and cyber attacks related to blockchain and cryptocurrency continue to follow. How to continue to promote financial innovation while also carrying out efficient risk prevention and control and effectively cracking down on illegal crimes is an important issue that requires long-term response. From a global perspective, China has responded with clear attitudes, strict measures, and effective measures in this regard.

The transaction changes realized by the blockchain in the real industry and financial industry are only the initial stage of the blockchain changing the traditional transaction method. The "Token Economy" is the blockchain "transaction" A higher level of functionality.

In "Token Economy"Under the framework of the , was given the “pass” function.

Regardless of the investment/speculation craze of "Non-Fungible Token (NFT)", we can already see many early applications of "token economy" around the world:

l The HotCity project supported by the Austrian government uses a crowdsourcing model combined with blockchain and gamification tokens to encourage residents to submit heating waste heat hotspots to meet urban heating needs more efficiently;< br />
l Ford establishes "Green Miles" for commercial and municipal fleets using hybrid vehicles to help improve urban air quality;

l Weibin District, Xinxiang City, Henan Province, in its In the blockchain industrial park project, tokens are issued based on the points system for merchants and enterprises to establish a new commercial service platform;

l Chengdu released a blockchain-based community governance product "Chain Community", Residents can earn "time bank" points on the platform through volunteer services and other activities, and exchange them for benefits and discounts provided by community merchants;

l Global non-profit organization "Mobile Open Blockchain Plan" The Electric Vehicle Charging Network Working Group (EVGI) launches a global standard system for decentralized vehicle charging technology, covering the Tokenized Carbon Credit (TCC) scenario;

l Blockchain reward platform MiL. k cooperates with a Korean retailer to provide blockchain-based points management services to its members. Members can convert existing points into local MLK tokens through the MiL.k platform, or exchange them into other third-party points...

As can be seen from the above cases and more, the "token economy" has several distinctive features:

The "token economy" gives assets to a wider range of data Attributes and tradable attributes, and through cross-domain and cross-platform mutual trust and circulation, can improve the operating efficiency of the entire social and economic system;

"Token economy" is a new value creation and The realization process does not necessarily use currency directly as the medium of exchange, but is more reflected in the exchange, mutual benefit and reallocation of various elements and resources;

"Token economy" is often combined with incentive mechanisms. At the same time, through incentives for "good people and good deeds", "good companies" and "good institutions", the social value system and social credit system will be effectively reshaped.

Generally speaking, the "token economy" will give birth to new factors of production, reshape production relations, and greatly liberate society.Productivity; the "Token Economy" represents the evolution of the "Information Internet" to the "Value Internet", indicating the most exciting future of the digital economy; the "Token Economy" based on the blockchain has begun to take shape, and has begun to It will bring about sustained and visible changes in economic operations, social governance, and everyone's lifestyle. All types of institutions and individuals should be mentally and physically prepared for this change.

Like other new technologies, in the process of application and popularization, blockchain continues to produce substitution effects in terms of platforms, media, models, methods, etc.: physical documents are replaced by electronic documents, and credit records are replaced by electronic documents. Tokens are replaced, manual review is replaced by data verification, and the city management platform is replaced by the "city brain"...

Such substitutions have become the norm:

l Argentina’s central bank has begun a proof-of-concept for a new blockchain clearing system, which may replace the existing clearing system;< br />
l Korea Minting and Security Printing Corporation (KOMSCO) expanded its blockchain digital gift certificate business to replace paper gift certificates and achieved record revenue despite a sharp decline in the issuance of banknotes and coins. Improvement;

l Courts across China have begun to use blockchain electronic seals to replace traditional paper seals in the enforcement of real estate seizures;

l The Shanghai court system is using artificial intelligence , the adoption of new technologies such as blockchain, and explore the use of digital court trial records to replace manual court trial transcripts;

l The Japanese company SUSMED launched a "Clinical Data Monitoring System Demonstration Using Blockchain Technology" pilot, indicating that the drug Or the necessary monitoring process in clinical trials of medical equipment can be replaced by a blockchain system;

l Alipay and Wukong Car Rental have cooperated to launch a "face-swiping" car rental service, which uses blockchain technology and credit-free security mode, tourists can rent a car by simply "swiping their face" and return the vehicle through mobile phone operations;

l Under the new crown epidemic, local governments in China have intensively launched "non-face-to-face" vehicles that combine blockchain technology ", no contact, zero errands" government service has replaced the traditional offline service method, providing a strong guarantee for the smooth progress of remote bidding, "cloud" customs clearance, financial support, resumption of work and production, etc. during the epidemic... .

In addition, we can also see that through the use of blockchain technology, various enterprise-level services are also realizing substitution and evolution: from paper contracts to electronic contracts, to program-based, Blockchain contracts that can automatically execute smart contracts. Blockchain is pushing contract signing into the era of "chain signing"; from offline human resources companies to online human resources platforms to the blockchain-based human resources market , global human resources services have experienced from the 1.0 era to the 2.0 era, and then to the 3.0 eraThe times continue to change.

Generally speaking, when the blockchain "invades" various industries, it will "mercilessly" delete all unnecessary links and processes, all unnecessary manual operations, and accelerate the The era of paperless, unmanned and automated is coming.

In the process of our analysis of more than 1,550 blockchain application cases around the world, words like "improve", "accelerate", "shorten", "lower", "reduce", "save", " Words such as "save" appear frequently in front of our eyes. These words show that the improvement of efficiency is the common pursuit of all parties involved in blockchain applications and is also the most direct result of the substitution effect of blockchain.

Numerous application practices are contributing to this:

l Kenyan company Shamba Records provides blockchain traceability, transaction and financing services to farmers in the country, currently covering more than 6,000 Small farmers and helped them increase their income by at least 40%;

l TradeWaltz, a blockchain trading platform invested by NTT DATA, Mitsubishi and other companies, completed a trial run, and the results showed that the platform can reduce traditional 50% of the workload of the trade process;

l Walmart Canada has significantly reduced invoice disputes with carriers by 97% through the application of the DL Freight blockchain platform;

l The State Grid Corporation of China’s power transaction certificate traceability inquiry platform has been put into operation, automating the entire authenticity review process for registered users and saving 99% of trusted manual review time;

l COSCO Shipping Lines and Shandong Port Group Qingdao Port have cooperated to launch a blockchain paperless import and delivery model, which can save customers nearly 24 hours on average per container;

l Taizhou, Zhejiang uses "materials" The "Internet + Blockchain" recycling system solves the problem of marine pollution control. Compared with traditional processing methods, this recycling system can save 94% of labor costs and 84% of operating costs...

In summary, through the joint action of trust mechanism, sharing mechanism and transaction mechanism, blockchain has formed an obvious substitution effect, improved the operational efficiency of finance, government affairs and various industries, and will Continue to create systemic change. This change is reshaping the relationship between people and machines, people and society, and people and the environment, and clearly points to three ultimate goals: efficiency, well-being, and environmental protection.

VII It’s 2021, what will be the development trend of my country’s blockchain technology in the future?

Domestic blockchain technology has been conceptualized a few years ago and has now been widely used It has been applied to actual business scenarios, such as the rice we eat, and the QR code on the packaging
Traceability is the application of blockchain technology. Companies like Shanghai Wanglian Technology,It entered the game early and is now developing very well.
