A. What is the concept of blockchain? Read it in three minutes!
On October 25, 2019, Xinwen Broadcast sent a very important signal: the country must vigorously develop blockchain. After that, blockchain has become an Internet celebrity, and the figure of "blockchain" is floating in the streets and alleys. In fact, many technology companies have already deployed blockchain technology.
Although blockchain is very popular, many people do not know much about blockchain.
What is blockchain?
Let’s first take a look at how Du Niang explained it. Network display: Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.
Why is blockchain called blockchain?
The blockchain is linked by blocks one by one, and the blocks are storage units that record the communication information of each block node. The blocks are much like the records of a database. Each block is a storage unit. Writing data every time creates a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.
What are the characteristics of blockchain?
Blockchain mainly has the following characteristics:
1. Decentralization: In the blockchain system, every node has equal rights. and obligations, there is no central control here. Decentralization has well established trust relationships with each other. Although there is no central management organization, people can collaborate with each other and trust each other. This mainly applies blockchain distributed ledger technology.
2. Openness: Blockchain data is open to everyone. Except for some encrypted information that is not open, everyone can check the data here.
3. Independence: The entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.
4. Security: Blockchain has a certain degree of security and cannot be tampered with. Because everyone in the blockchain system has the same ledger, if someone wants to tamper with it, it is possible to forge a non-existent record only if they control more than 51% of the accounting nodes. Of course, this is basically impossible. This is mainly due to the core technology of the blockchain: the consensus mechanism. The consensus mechanism has the characteristics of "the minority obeys the majority" and "everyone is equal".
5. Anonymity: Many people think that if the blockchain is so open and transparent, will we lose privacy? Actually not. Although the transaction information in the blockchain is open and transparent, the identity information of the account is encrypted and can only be accessed if authorized..
Now let me tell you a story to help you better understand the blockchain.
There are three people in the family, mom, dad, older brother and younger brother. Last year, my father was in charge of the family's account books. He was responsible for all the family's income and expenses alone.
However, on the day of Double Eleven, my mother, who has always been frugal, wanted to buy herself a beautiful piece of clothing on a certain online store. When she checked the account book, she found something was wrong. It stands to reason that except for some money deposited in banks and financial management, the whereabouts of the daily consumption money at home are all in this account book, but no matter how you look at it, it is wrong. Some consumption is clearly not recorded, but is recorded.
Later, my father took the initiative to confess that he couldn’t help but buy a pack of cigarettes.
Later, my mother changed her strategy and the whole family kept accounts. Everyone recorded their monthly consumption expenditure in their own account books. Whenever there was a transaction or consumption at home, my mother would shout, "Book it," and everyone would record the transaction in their own books. This is the decentralized accounting model, where everyone is the center and everyone has a ledger.
The previous accounting model for dad was centralized accounting. If dad wanted to do something alone, it would be difficult for anyone to see it. The decentralized accounting model has solved the problem of centralization very well. The disadvantage of bookkeeping is that it is very difficult for dad to tamper with the books.
For example, if my father wants to take some money from the ledger and secretly buy cigarettes, the amount of money is limited, and if he wants to take the money, he has to change the ledger, but he only tampered with his own ledger. No, he had to change the accounts of three people including himself. And this is undoubtedly more difficult than reaching the sky.
So, many times my father had the idea of smoking, but he had no choice but to give up the idea due to the current situation.
Are blockchain and Bitcoin the same thing?
In fact, blockchain and Bitcoin are not the same thing. It is just the underlying technology of Bitcoin. Bitcoin is the first digital currency applied by blockchain.
In 2008, Satoshi Nakamoto first proposed the concept of blockchain. In the following years, it became a core component of the electronic currency Bitcoin, serving as a public account book for all transactions. Blockchain was first applied to Bitcoin.
The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.
What are the applications of blockchain?
The application of blockchain is actually very wide. In addition to digital currency, the future applications of Bitcoin are still very extensive. Blockchain technology has been widely used in different industries. Such as product traceability and copyright protectionWith transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., it promotes different industries to quickly enter the "blockchain+" era.
1. Payment and clearing: Blockchain can abandon the role of transit banks, realize point-to-point payment, reduce transit fees, and accelerate fund utilization.
2. Product traceability: For example, if we buy a piece of clothing on a certain store, we can see the past and present life of this piece of clothing.
3. Securities trading: Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.
4. Supply chain: Introducing blockchain technology into the supply chain system, synchronizing information within the system can control all links, better complete division of labor and collaboration, and facilitate subsequent accountability.
5. Intellectual property rights: With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.
B. What is the difference between blockchain and supply chain
Blockchain Blockchain is: distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies New application models. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
The definition of supply chain is: around the core enterprise, starting from supporting parts to making intermediate products and final products, and finally delivering the products to consumers through the sales network, from suppliers, manufacturers, distributors to The overall functional network chain structure connected by end users.
C. What role can blockchain play in traditional enterprises
Blockchain is a new application of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. Blockchain is essentially a decentralized database.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.
Take agriculture as an example, what problems does blockchain solve in agriculture?
1. Traceability of agricultural products
The traceability of agricultural products has always been a pain point in agriculture. Blockchain technology can make records non-tamperable, so there is detailed data from the production end of agricultural products to the circulation end and consumers, which can realize consumers' clear consumption and increase consumers' willingness to buy.
The traceability of agricultural products can improve the safety of agricultural products and food.
2. Information transparency
In addition to traceability in the agricultural field, there is also the problem of opacity in the information between producers and demanders.
Once blockchain technology is applied to agriculture. You can use big data analysis to establish credit rating references for growers and buyers.; Use smart contracts to ensure fair transactions between growers and buyers. At the same time, blockchain technology can improve the contractual spirit between buyers and sellers of agricultural products.
Also, with the advent of blockchain in the food supply chain, this could streamline the process as the data management system integrates a range of brokers, farmers, processors, distributors, regulators, retailers and Data management systems are becoming more transparent for consumers to put on their radar.
3. Reduce costs
After the application of blockchain technology, the costs of production and circulation will be greatly reduced. For example, blockchain technology solves the functions of automatic information storage and database, thus reducing manual investment and investment in other facilities.
In addition, blockchain and applications realize the interconnection of everything, helping manufacturers and distributors reduce various expenses. At the same time, reductions in production and distribution costs will also reduce the prices of agricultural products, ultimately benefiting consumers.
Of course, in addition to the above three reasons, blockchain technology can also be applied in agricultural subsidies, land registration, etc. to solve problems such as corruption and rights and interests.
Therefore, the application of blockchain technology in the agricultural field has been recognized by people at all levels.
The core advantage of blockchain technology is decentralization. It can realize decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thereby providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
Future development and application scenarios of blockchain
1. Digital identity
When many people apply for various certificates, they will encounter "prove that my grandma is an adult", "my mother is my mother" "The dilemma, with blockchain, you no longer have to worry about it. It turns out that our birth certificates, real estate certificates, marriage certificates, etc. need a central node for everyone to recognize them. Once cross-border, contracts and certificates may become invalid because of the lack of a global central node.
The non-tamperable nature of blockchain technology has fundamentally changed this situation. Our birth certificates, real estate certificates, and marriage certificates can all be notarized on the blockchain and become things trusted by the world. Of course, It can easily prove "prove that my grandma is an adult" and "my mother is my mother".
2. Health care
To put it simply, it is to use blockchain to establish a universal record repository with timestamps, so that different databases can extract data information.
3. Travel consumption
When traveling, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform gets commissions from them. The application of blockchain is to remove middlemen and create a secure and decentralized way for service providers and customers to connect and trade directly.
4. More convenient transactions
Blockchain can make payments and transactions more efficient and convenient. blockchain flatThe platform allows users to create smart contracts that become active when certain conditions are met, meaning that automatic payments can be released when both parties to the transaction agree that their conditions are met.
5. Strictly control product quality
If you buy an apple, with blockchain technology, you can know the entire process from the production of the fruit farmer to the circulation link. Among them are government regulatory information, professional testing data, enterprise quality inspection data, etc. A smart supply chain will make the food we eat and the products we use every day safer and give us more peace of mind.
6. The Art of Property Rights Protection
The creator puts his work on the blockchain, and once someone uses his work, he can know it immediately. Corresponding royalties will also be automatically paid to the creator. Blockchain technology not only protects copyright, but also helps creators sell their works to consumers better and more directly, without requiring the assistance of distribution companies.
D. What is the difference between blockchain and supply chain?
Blockchain is a kind of decentralized data processing, and supply chain is the internal and external supply relationship that an enterprise maintains normal operation. , the application of blockchain in supply chain will bring about subversive changes.
Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The supply chain refers to the network chain structure formed by upstream and downstream enterprises involved in the provision of products or services to end users in the production and circulation process.
Management methods
Common Supply chain management methods include Quick Response (QR) and Effective Customer Response (ECR).
Quick Response (QR) means that when logistics companies face a buyer's market with multiple varieties and small batches, they do not reserve "products" but prepare various "elements" to respond to user requests. At the same time, the "elements" can be extracted as quickly as possible, "assembled" in time, and the required services or products can be provided. QR is a supply chain management method developed in the U.S. textile and apparel industry.

E. This article summarizes the nine major benefits that blockchain technology brings to enterprises
The launch of Bitcoin, the first application of blockchain, in 2009 transformed blockchain from a theoretical application to a practical application, proving that this digital distributed ledger technology is indeed effective. Since then, many enterprise organizations have been testing how to make blockchain work for them.
Now, well-known companies, government organizations and non-profitFor-profit entities are also trying to use blockchain to improve existing processes and enable new business models.
Blockchain’s value stems from its ability to share data between entities in a fast and secure manner—without any entity being responsible for protecting the data or facilitating transactions.
"This is a transaction ledger with unique characteristics that help solve problems in our systems and processes," said Associate Professor in the Department of Information Technology and Analytics at American University and Research Fellow at the Kogod Center for Cybersecurity Governance Ayman Omar explains.
From Maoqiu Technology’s perspective, blockchain and its features can, in fact, help enterprises in a variety of ways – whether they use a public blockchain network or choose a private or permissioned zone-based one. Blockchain applications.
Maoqiu Technology The following are the main advantages of blockchain:
Blockchain creates trust between different entities where trust does not exist or is unverified. As a result, these entities are willing to engage in commercial transactions involving transactions or data sharing that they might not otherwise do, or would require an intermediary to do so.
The realization of trust is one of the most promising advantages of blockchain. Its value is evident in early blockchain use cases that facilitate transactions between entities that are not directly related but still need to share data or make payments. Bitcoin, and cryptocurrencies in general, are prime examples of how blockchain enables trust between participants who do not know each other.
Daniel Field, Head of Blockchain at UST Daniel Field, Head of Blockchain at UST, a global provider of digital technologies and services, explains that when there is no central actor facilitating trust, blockchain The chain has truly proven its value.
Thus, in addition to enabling trust when participants lack trust because they don’t know each other, blockchain can enable data sharing in an enterprise ecosystem where no single entity is solely responsible.
Supply chain is a good example. Multiple businesses—from suppliers and transportation companies to manufacturers, distributors, and retailers—want or need information from others in the chain, but no one is responsible for facilitating the sharing of all this information. Blockchain solves this problem with its decentralized nature.
The security of blockchain-enabled systems is another major advantage of this emerging technology. The enhanced security provided by blockchain stems from how the technology actually works. Blockchain creates an immutable record of transactions through end-to-end encryption, which keeps fraud and unauthorized activity at bay.
In addition, data on the blockchain is stored in a computer network and is almost impossible to be hacked (Unlike traditional computer systems that store data in servers). At the same time, blockchain can limit access by anonymizing data and requiring permissions, solving privacy issues better than traditional computer systems.
Blockchain can also reduce costs for companies, increase efficiency in processing transactions, and reduce manual tasks such as aggregating and modifying data, as well as streamlining reporting and auditing processes.
Experts point out that financial institutions will significantly reduce costs when using blockchain, explaining that blockchain’s ability to simplify clearing and settlement directly translates into process cost savings. More broadly, blockchain helps businesses cut costs by eliminating the middlemen — vendors and third-party providers — that traditionally provide the processing that blockchain can do.
By eliminating intermediaries and replacing remaining manual processes in transactions, blockchain can process transactions faster than traditional methods. In some cases, blockchain can process transactions in seconds or less. However, times may vary.
How quickly a blockchain-based system can process transactions depends on a variety of factors, such as the size of each data block and network traffic. Nonetheless, experts have concluded that blockchain generally outperforms other processes and technologies in terms of speed. In one of the most prominent applications of blockchain, Walmart used the technology to track the origin of mango slices in seconds—a process that previously took seven days.
Walmart’s use of blockchain isn’t just about speed; it’s also about the ability to trace the origins of these mangoes and other products. This allows retailers like Walmart to better manage inventory, respond to issues or questions, and confirm the history of their merchandise.
If a specific farm has to recall its products due to contamination, retailers using blockchain can identify and remove products from that specific farm while selling their remaining products. According to experts, blockchain can help trace the origin of various items such as pharmaceuticals to confirm that they are legal as opposed to counterfeit and organic items to confirm that they are indeed organic.
Immutability simply means that a transaction cannot be changed or deleted once it is recorded on the blockchain. On the blockchain, all transactions are timestamped and date-stamped, so there is a permanent record. Therefore, blockchain can be used to track information over time, allowing for safe and reliable auditing of information.
For example, Omar pointed to Sweden's use of blockchain to digitize real estate transactions to track property ownership even as they change hands as an example of this benefit.
Experts say blockchain could enable unprecedented personal control over one’s digital data. Michela Menting, research director at ABI Research, said: “In business, data is extremely valuable.In the world of products, this technology essentially protects the data that belongs to you while allowing you to control it. ”
Individuals and individual organizations can decide what digital data they want to share, with whom and for how long, and enforce restrictions through blockchain-enabled smart contracts.
However, universities that allow participating universities to provide information about their graduates and A pilot program in which degree-granting data is placed on the blockchain and then accessible to authorized hiring managers helps solve both problems—getting to the truth and getting to the truth quickly and efficiently.
Experts say executives need to carefully consider where they invest in blockchain.
The real value of blockchain, they stress, lies in its use in areas where traditional databases don’t work and in the absence of central control Or in a case of trust.
“If there is a high level of trust, blockchain has no problems to solve. But the less visibility or possibility of corruption you have, that's where you have a bigger use case. This is where blockchain becomes the solution,” Omar said.
Blockchain-based applications can also be paired with artificial intelligence, machine learning or some other decision-making layer, he said.
However, experts still believe that blockchain will bring disruption and transform businesses—even if the revolution doesn’t happen anytime soon.
It’s important to understand that There's a lot of hype around blockchain, and while it's revolutionary in theory, it's not going to change society today," Mentin said. "Maybe it will appear 10 to 20 years from now, but this is not a short-term technology."
F. Popular explanation of what blockchain is
Question 1: Blockchain What is it? Can you explain the principle of 10-point blockchain in plain language: a decentralized distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases , which enables transactions to be based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly conduct payment transactions without the participation 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. oneA block contains the following three parts: transaction information, hash of 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 and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and 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, bringing globalThe basic values of freedom and equality required by a unified market should be programmed, agreed upon, and enforced. 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, each country's legal currency has different credit values and incompatible clearing systems, 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
In the future, personal assets can be traded through this P2P wallet 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 some applications in other aspects, the Internet of Things and so on.
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 underlying 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.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 attract more and more attention, and a huge new trend will form...> >
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 from A's name, and add 80,000 yuan to B's name. 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", a new form of distributed artificial intelligence, and will establish a new interface and shared interface for 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. At present, it is whoever owns the system who keeps the accounts. WeChat’s account books are kept by Tencent, and Taobao’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 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 represented by Bitcoin, 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 interpretationsInterpretations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are also 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 Bitcoin has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities, the blockchain technology used in Bitcoin has been recognized by governments, including governments and monetary authorities. extensive attention.
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 brand-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 makes people’s trust in the blockchain technology used in BitcoinPeople are increasingly aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, blockchain is not the same as Bitcoin, and its application will never be the same. Only 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 areas, 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 agreements (rules or constitutions). 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 similar to the big data often involved in social networking (WeChat) and payment platforms (Alipay, Yibao).
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 it, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be saved permanently 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!
G. Does blockchain need to be adopted by all companies in the supply chain?
Blockchain needs to be adopted by all companies in the supply chain. According to relevant public information, blockchain and supply chain are inseparable. Blockchain can play a role in the planning, procurement, manufacturing, delivery, and recycling of the supply chain. Therefore, blockchain needs to be adopted by all companies in the supply chain. of.
H. Blockchain can improve the transparency and flexibility of the supply chain
Today’s market competition has become increasingly dynamic and demanding, resulting in a challenging competitive environment. To adapt to this dynamic environment, supply chains increasingly rely on collaboration, integration, flexibility and trust among those taking over. Therefore, new technology applications are becoming increasingly important in supply chains.
In order to improve supply chain process control, Maoqiu Technology believes that modern professional applications must be implemented. Blockchain technology has become an essential part of today’s competitive environment. Companies should invest in blockchain technology to quickly respond to changing market conditions and demands in today’s dynamic business environment.
According to a paper report released by MDPI, blockchain solves the two main problems of traceability and transaction irreversibility in the supply chain, thereby effectively improving the transparency of the supply chain. Transparency, as a point of importance to all stakeholders in the supply chain, can ensure that product information can be viewed and obtained in a timely manner, thereby reducing losses caused by information delays.
Supply chain transparency is primarily based on information about the movement of products along the supply chain. If companies are to maintain the ability to proactively communicate with stakeholders to gain visibility and traceability of supply chain operations, they can ensure the visibility and Accessibility.
In the above manner, stakeholder feedback can be included in the blockchain to improve the performance capabilities of the supply chain. In addition, the history of a product can be tracked throughout the supply chain, and a clear picture of current activity can be displayed. Companies can clarifyClarify core values to reduce uncertainty in public markets, thereby confronting environmental or social issues through transparency.
Many stakeholders have high hopes for blockchain because of its capabilities such as real-time information sharing, security, immutability, and transparency. With its proof-of-work and distributed database structure, blockchain can increase supply chain transparency while using real-time distributed data sharing to enable stakeholders to identify data related to product quality, location, transactions and procedures.
These capabilities of blockchain enable product tracking, allow for comprehensive product verification and product authorization throughout the transaction process, and provide end-to-end auditing based on permissions across the organization. Blockchain reduces the opportunistic behavior of trading partners in terms of information tampering, corruption, fraud, etc.
Therefore, blockchain provides transparency in transactions between trading partners, thus increasing trust, and blockchain strengthens the relationship between suppliers, customers, outsourcing, The relationships between 3PLs and subcontractors make the supply chain more efficient and transparent.
Blockchain technology can help build trust and reputation by bringing transparency to supply chains. Large-scale blockchain solutions have the ability to completely redesign reputation management and detect fraud across entire networks. Blockchain consensus provides a solid foundation for the unification of opinions and the ability to achieve higher transparency. Establishing a decentralized supply chain based on blockchain technology instead of a centralized supply chain in the supply chain obviously has the advantages of being more efficient and transparent.
As supplies become more widely distributed, the risk of conflicts, mismatches and inconsistencies in traditional supply chains increases. Blockchain can allow for better tracking and reporting, increasing transparency in supply chain processes, thereby improving delivery schedules. For example, GPS-based vehicle tracking devices can be used with blockchain to provide the blockchain with data that cannot be overwritten and tampered with, which can reduce costs and increase efficiency when it comes to logistics vehicle tracking.
Contemporary supply chains are more complex, dynamic and uncertain than ever because they involve many departments. So creating a flexible supply chain is key to achieving sustainable competitive advantage. A flexible supply chain improves delivery processes and quickly moves products to required markets.
Business transactions are becoming increasingly volatile and global. Agility is achieved when a company can effectively respond and adapt to competitor disruptions and demand changes throughout the supply chain to meet customer needs.
Rapid economic and technological development requires increased flexibility in both internal (marketing and manufacturing) and external (supply and distribution) supply chains. Companies with flexible supply chains can be more resilient in uncertain situations. Respond quickly and provide the company with the ability to demonstrate products and services quickly and effectively.
In a globalized world, competition has spread to the entire supply chain, not just companies. Therefore, supply chain members need to reorganize themselves to balance the organization's ability to respond to market changes by increasing flexibility.
In today's economic environment, companies outsource some business processes to ensure supply chain flexibility, which often results in a loss of control and visibility of various logistics operations. Thanks to digital technologies, visibility into integrated transport and logistics systems will be achieved at all stages of goods delivery, from manufacturer to end user. Companies need to share information directly so it can be quickly applied to every company in the supply chain, thereby increasing supply chain agility.
So this requires different information to ensure that the chain can function as a whole. Therefore, information transferred from one organ to another should be helpful and available elsewhere in the chain.
Blockchain technology serves customers by facilitating tracking and tracing of orders from various stages of production to delivery and quick adjustments. The applications brought about by blockchain technology can only be implemented at specific touch points in the network if accepted by the relevant parties, thus controlling the data security of all supply chain transactions.
Blockchain can increase supply chain visibility and enable real-time data sharing over the network. Therefore, blockchain can support supply chain flexibility strategies by reducing the number of stakeholders affected by disruptions.
At the same time, blockchain can also quickly integrate all on-chain processes to improve forecasting and management of demand, thereby achieving more realistic supply and inventory management.
Blockchain technology has become one of the most common concepts today. As digitization becomes a common phenomenon, we have begun to digitize our assets.
Blockchain can serve as an effective tool to build trust in the supply chain by increasing transparency and flexibility in the supply chain. However, Maoqiu Technology also believes that the real implementation of blockchain in supply chain applications cannot be separated from mutual trust between enterprises. Only in this way can an effective consensus foundation be formed, mutual collaboration capabilities can be improved, and the operating efficiency of the supply chain can be improved.
I. What is the difference between supply chain and blockchain?
Supply chain is an application of blockchain.
The core analysis:
1. Transparency, 2. Openness, 3. Information cannot be tampered with, 4. Decentralization,
5. Detailed analysis.
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
1. In a narrow sense, blockchain is a chain data structure that combines data blocks in a chronological order and is encrypted.An untamperable and unforgeable distributed ledger guaranteed by coding methods.
2. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. A new distributed infrastructure and computing method that securely uses smart contracts composed of automated script codes to program and manipulate data.
