A. What is the difference between regional chain and blockchain?
Blockchain is not a single individual, but a chain structure that connects many block structures together. Each block is then connected to form a specific collection or area. So there is actually no difference between blockchain and regional chain. The term regional chain is actually another expression of blockchain. Blockchain technology is the underlying technology. Without the operation and management of any centralized organization, it has been running very stably for many years without any problems. Therefore, some people noticed its underlying technology and extracted the technology abstractly, calling it Blockchain technology, or distributed ledger technology. When we search for regional chains, we will automatically jump to the search results page of blockchain, so we can list blockchain and blockchain as synonyms.
Extended information
1. What is blockchain?
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system
Blockchain is a very important technology. Huobi.com cooperates with the Internet Finance Laboratory of Tsinghua University PBC School of Finance , the "2014-2016 Global Development Research Report" released by Sina Technology mentioned that blockchain is the underlying technology and infrastructure. Essentially a decentralized database. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Ledger.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.
Blockchain _ The original blockchain is a decentralized database that contains a list called blocks, with continuously growing and neatly arranged records. Each block contains a timestamp and a link to the previous block: Blockchains are designed so that data is immutable—once recorded, the data in a block is irreversible.
The design of blockchain is a protection measure, such as (applied to) highly fault-tolerant distributed computing systems. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that require data collection, identity management, transaction process management and provenance management. Blockchain has huge potential for financial disintermediation and has a huge impact on leading global trade.
2. What is a regional chain?
The two words "region chain" and "blockchain" are different in only one word. Do they have the same meaning? Let's take a look at the meaning of the two words block and domain. A block can be understood as a part of the whole, and a domain refers to a specific area or a specific whole.
Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.
Broadly understood, 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 the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.

International problems: cross-chain technology
In order to solve the problems of the traditional Internet world The problem of information islands. Blockchain uses the structure of a decentralized network to try to achieve information sharing to solve the problem of data islands. However, with the emergence of many blockchain applications, the blockchain chains are not interoperable, causing the blockchain to also face this "isolated chain" dilemma. It is not in line with the original intention of the blockchain.
How to implement multi-chain coexistence on the same blockchain platform based on business functions, privacy protection, data isolation, performance and capacity expansion needs, etc. How to implement information and business interaction between blockchain platforms with inconsistent identity access mechanisms, information standards, and business forms. It is expected to become an important direction of development.

C. What kind of technology is "blockchain"
What kind of technology is "blockchain"? Blockchain is an important concept of Bitcoin. Huobi, Tsinghua University PBC School of Finance's Internet Finance Laboratory and Sina Technology released "2014— The 2016 Global Bitcoin Development Research Report mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Account book. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include an asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.
Blockchain is a decentralized, distributed ledger system involving nodes. The data stored on it cannot be forged or tampered with, and the public information cannot be forged or tampered with.Open and transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol provide the necessary foundation for the execution of smart contracts. The contract can be automatically executed and trusted according to established conditions without the need for auditing by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone on the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
Openness and transparency, once all information recorded on the blockchain is recorded, it will be very It is difficult to tamper with and cannot be hidden, and users can check it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in major decisions.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trusting relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us.The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanisms. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here. Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.
Introduction to Bubi Blockchain
Bubi Blockchain is mainly positioned to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building on top of the blockchain system. A support system with high expandability. On top of this support system are applications from all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain can indeed bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the function of currency as a medium of exchange). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even if you areDevelopers in the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of various disputes about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
Bitcoin company BTCC launched in 2015A service "Millennium Chain", a blockchain engraving service, has been launched, which adopts the above principles. Users can engrave text on the blockchain through this service and store it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet with data blocks (Block). The road's reliance on the central server enables all data changes or transaction projects to be recorded on a cloud system, theoretically achieving self-certification of data during data transmission.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, Issue numberable, 100% editions of your work 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.
Legal Industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when storing data on the blockchain is too large, the data can be stored on the BitTorrent network.
Internet Mutual Aid Industry
Tongxin Mutual Aid is the first blockchain online mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, we will eliminate the shortcomings of the traditional online mutual aid model and establish an open and transparent new online mutual aid platform.
Aite Cat is a virtual pet game produced under blockchain technology. This virtual cat is similar to Internet Letts Dog, 360 pet cat, and NetEase’s Planet are all the same type of blockchain virtual products. The difference between Aite Cat is that the entire cat design uses a 3D three-dimensional effect, making the cat’s The display is no longer a single picture, allowing the cat to move, which increases the fun of the cat.
What technology is the Huangbao blockchain system?The Huangbao blockchain is a powerful decentralized loop intelligence system. The Huangchain chain is referred to as HUANG. It is the first to be used in financial services, advertising media, games and entertainment, various life applications and other fields, becoming a blockchain 3.0 The representative virtual currency of the era, Media Chain 3.0 technology has the core characteristics of being safer, more efficient, more flexible, and more open. The widespread application of its technology will surely trigger new forms and new ideas in the global media industry, which can Create convenient services and new concepts, which marks a new economic era before the public.
D. What is the major of blockchain technology?
Blockchain technology is the underlying technology of Bitcoin. In the early days, not many people paid attention to the underlying technology of Bitcoin. But when Bitcoin is operated and managed without any centralized organization, it has been running very stably for many years without any problems. Therefore, many people have noticed that the underlying technology may have a large mechanism, and it may not only be used in Bitcoin, but may be applied in many fields. So the Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology. So from a certain perspective, Bitcoin can be seen as the first application of blockchain, and blockchain is more similar to underlying technologies such as TCP/IP, which will expand to more and more industries in the future.
The main advantages of blockchain are that it does not require intermediary participation, the process is efficient and transparent, the cost is very low, and the data is highly secure. Therefore, any industry that has needs in any of these three areas has the opportunity to use blockchain technology. For example
1. Banking 2. Payments and transfers 3. Cybersecurity 4. Academic records 5. Voting 6. Car rental and sales 7. Network and Internet of Things 8. Forecasting 9. Online music 10. Ridesharing 11. Stocks Trading 12. Real estate 13. Insurance 14. Healthcare 15. Supply chain management 16. Cloud storage 17. Energy management 18. Sports management 19. Gift cards and customer loyalty programs 20. Government and public welfare
E . What are the survival rules at the bottom of the blockchain food chain
We know that there is such a "chain of contempt" in the financial circle: the banking industry looks down on Wall Street investors, and investors look down on stock traders.Stock speculators look down on fund speculators, fund speculators look down on real estate speculators, and real estate speculators look down on Bitcoin traders. But you may not know that there is also such a "blockchain food chain" in the cryptocurrency industry.
This term sounds unfamiliar, but it reveals the reality of each section of the crypto mining industry chain. In this long blockchain industry
, one end is resource-heavy links such as mining machines and electricity, and the other end is heavy operation links such as mining pools and wallets. Then miners shuttle throughout this entire chain.
It is really difficult to make profits in this process. Regardless of whether it is the arrival of a calf or a big bull, miners are still surviving in the cracks
despite the favorable tide, and their profits are meager. This made the miners shout: "Miners are always at the bottom of the mining ecosystem."
As miners at the bottom of the blockchain food chain with no right to speak, how did they survive in this lengthy process? What about those who are struggling in the food chain? They
have their own "bottom survival rules".
(1) Mine:
Between the mine and the miners, the core production factor is electricity. In fact, the vast majority of miners get second-hand or even third-hand
flashlights, and they have no chance to get first-hand cheap electricity. At the same time, they often face harsh situations such as market highs, black-box operations in mining circles, and price hikes
.
So experienced miners realized the method of “pre-risking”. That is to say, priority is given to selecting high-quality mines with previous cooperation experience, and secondly, when selecting
new mines, the conditions and quality of the mines are strictly measured. When the cooperation is finally implemented into the contract, it is best to implement it in numerical values rather than vague textual concepts
or textual descriptions. Through these risk-forward strategies, they can effectively avoid certain risks.
(2) Mining pools:
Mining pools, as technical service providers for the crypto-mining ecosystem, are mixed in terms of good and bad, which also gives miners a headache. In the process of choosing a cooperative mining pool
, it is extremely important for miners to judge the quality of the mining pool.
After paying the tuition fee for the mining pool, experienced miners have three criteria when choosing a mining pool: The first is the brand effect because of its hidden technology
The second is the scale of computing power, because it directly affects mining income; the third is human resources, because it can
effectively avoid disputes afterwards.
(3) Rights protection:
Miners are at the bottom of the blockchain food chain, which often means that their rights protection journey will be particularly difficult. After all, today's cryptocurrencies still have
regulatory gaps, and the crypto mining industry, which has not yet perfected legislation, has no way to protect the already vulnerable miners. Not only were there no standardized industry
regulations in the early days of the industry, miners often did not sign written contracts when cooperating with mining pools. When encountering unfair treatment, miners often had no choice but to "break their teeth
/>
Swallow it into your belly."
Many miners were forced to change careers. Many miners who stick to the industry place more hope in authoritative social groups or strong network resources, hoping that some prestigious authoritative institutions or community organizations can expose vicious incidents. and liars.
Just because of the "quick money", more and more people are flocking to the mining industry, but it always comes and goes in a hurry. Only a few old miners
have not forgotten their original aspirations, stick to their posts, maintain their faith in blockchain technology, and become the cornerstone of the entire encryption market. We hope that when the crypto market is booming, more people will pay attention to these miners who lack the right to speak, because they have never stopped busy,
Only then can the market development and future of the blockchain industry rise step by step today.
F. What is Blockchain
In the simplest terms, blockchain is a distributed ledger.
To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.
The following is our process for using bank debit card transactions:
You can swipe your card to purchase goods in stores.
The merchant sends a statement to your bank for the agreed upon amount.
Your bank will verify that you may have authorized the purchase.
The bank sends the money to the merchant.
Finally, the bank records this information in its ledger.
There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.
This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.
Crucially, if hackers were able to access a bank's ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.
This is why distributed ledgers are so cool.
Blockchain Network Visualization
If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.
Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.
On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).
As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.
The future of blockchain, how will it change our lives?
One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.
Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.
This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.
Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.
Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle
G. What signals does the blockchain 3.0 era give us?
In 2020, blockchain will beIncorporated into the category of “new infrastructure”, at least 7 provinces have introduced blockchain support policies. In the same year, blockchain technology was gradually moving from concept to implementation, with many application scenarios blooming. Various industry applications of "blockchain" have become a symbol of the continuous maturity of blockchain.
The development status of "blockchain" in 2020
In 2020, the COVID-19 epidemic swept the world, and the uncertainty of world economic development increased significantly. Governments and enterprises of various countries are exploring the use of emerging technologies to reduce economic and social operating costs, improve the operating efficiency of the real economy, and further find new growth points for economic development.
At present, blockchain is cross-innovating with new technology infrastructure such as cloud computing and artificial intelligence. More and more vertical fields of the real economy are showing the development pattern of "blockchain" and the "elimination trend". "real" good momentum.
In order to avoid turning reality into fiction, in addition to continuing to severely crack down on speculation, we must also guide the deep integration of blockchain technology with practical application scenarios. Therefore, various industrial application scenarios of "blockchain" have become one of the inevitable trends in the development of blockchain.
According to the "Blockchain White Paper (2020)" recently released by the China Academy of Information and Communications Technology, as of October 2020, more than 262 listed companies have been involved in the blockchain field, each from insurance , real estate, commercial department stores, security equipment, packaging materials, telecommunications operations and other 39 fields. In the blockchain information service registration list released by the State Internet Information Office, there are 45 blockchain projects of listed companies.
Among them, finance is the most explored scenario among blockchain technology application scenarios, with specific projects implemented in subdivisions such as supply chain finance, trade finance, payment and settlement, and fund management. The white paper shows that as of November 2020, among the domestically registered blockchain information services, the number of projects in the financial (including supply chain finance) field ranks first, accounting for as high as 36%.
As the implementation of blockchain applications accelerates, "blockchain" business has become the focus of development for Internet backbone enterprises to enter the blockchain industry. In addition to financial business, they actively deploy the Internet, traceability, and supply. Applications in chain & logistics, digital assets, government affairs and public services, intellectual property, law, medical and other fields.
At the same time, the industry is gradually understanding that blockchain is the basic component of trusted transactions, but this does not mean that blockchain can conquer the world. Blockchain needs to be combined with other technologies such as artificial intelligence, Internet of Things, big data, 5G, etc. to use synergy to form integrated solutions to jointly promote digital transformation.
According to relevant data, the current application of blockchain is mainly in the field of certificate storage. Blockchain has entered into how to make it better from an engineering perspective, more credible, more stable, and more scalable. Well, a stage that can accommodate more nodes. He Baohong, director of the Institute of Cloud Computing and Big Data of the China Academy of Information and Communications Technology, believes that this process will continue for some time or longer. In the next step, blockchain technology competition will shift from engineering optimization and improvement to technology ecology and business ecology..
In addition, it is understood that the blockchain industry is improving in the long term, and industry cognition has returned to rationality. With the central government's planning and guidance for the development of blockchain technology, my country's blockchain has clarified the development ideas based on the alliance chain, focusing on serving the real economy and optimizing public services, and the direction of industrial development has become clearer. At this stage, the confidence of the majority of practitioners in blockchain continues to improve, and the long-term strategic value of blockchain is generally recognized.
What is the prospect of “blockchain” in 2021?
As my country’s blockchain industry chain gradually improves, most blockchain companies not only focus on one aspect, but also show a trend of coordinated development in multiple fields. According to statistics, among the 801 blockchain information service registration lists released by the Cyberspace Administration of China, Beijing, Guangzhou, Shanghai, Zhejiang, Jiangsu, and Shandong are the provinces and cities with the most registered companies.
The core role of blockchain corresponding to its technical characteristics is mainly reflected in the three aspects of certificate storage, automated collaboration and value transfer. As its value potential is constantly being explored, application scenarios have evolved from the breakthrough point of finance. , and gradually expanded into many fields such as the real economy, government affairs and people's livelihood.
The core value of blockchain for the real economy is to promote efficient collaboration between upstream and downstream industries and improve the efficiency of industry-finance integration. In the early stages of development, the blockchain application model mainly focused on the storage of documents, contracts, etc. At this stage, blockchain industry applications are gradually moving towards automated collaboration and value interconnection such as government data sharing, supply chain sales collaboration, and cross-border trade.
2020 is the warm-up for 2021. In 2021, the use of blockchain, distributed ledgers, and smart contract tools will continue to grow as it did in 2020. With the continuous deepening of blockchain technology, the foundation of the blockchain industry will become better and better, the industrial ecology will also develop rapidly, and the industrial chain will become increasingly widespread.
From the perspective of industrial structure, the blockchain industry is mainly divided into four parts: underlying technology, platform services, industrial applications, and peripheral services.
The first three parts show a relatively obvious upstream and downstream relationship. The underlying technology part provides the necessary technical products and components of the blockchain respectively. The platform service part builds an area that can run corresponding industry applications based on the underlying technology. The industrial application part of the blockchain platform mainly uses blockchain technology to develop industry applications based on the actual scenarios of various industries and realize the innovation of business collaboration models within the industry.
The peripheral services part provides supporting services to the industry, including industry organizations, market research, standard formulation, system evaluation and certification, industry media, etc., to provide impetus for the development of industrial ecology.
Among them, as far as the industrial application of blockchain is concerned: Blockchain is the innovative development result of information technology, and it is also the main booster for the reconstruction of business processes and the innovation of industrial interaction models in various industries.
Blockchain has gradually expanded from the initial digital finance to supply chain finance, product traceability and other fields. Now it has been explored and applied in government affairs, people's livelihood, industrial management and other industries, and its application scenarios are becoming increasingly rich, presenting It has shown a development trend of deep integration with other industries.
Currently, domestic companies are focusing on the development of applications related to serving the real economy and improving government affairs and people's livelihood. Among them, supply chain finance and product traceability have accounted for half of all applications. Others, such as government affairs and people's livelihood, have become key areas for manufacturers to deploy in the future. There is going to be explosive growth.
After blockchain investment cooled down in 2020, the blockchain industry may begin to gradually become more rational in 2021. However, a relatively complete industrial chain and active market entities provide a good foundation for the integrated development of the blockchain industry. The blockchain industry will also show a positive development trend in terms of policy support, ecological construction, platform services, application implementation, and integrated innovation.
H. What is blockchain_What is blockchain technology
What is blockchain
Blockchain has become quite popular recently. Let’s talk about it People will associate Bitcoin with blockchain, but blockchain is blockchain and Bitcoin is Bitcoin. The two are completely different. Although many people have heard of blockchain, they don’t understand the difference. What is blockchain? What exactly does blockchain mean?
Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. Many people still don’t understand decentralization. Decentralization means that there is no central ledger in the blockchain. Everyone has the opportunity to participate in accounting. Everyone is the center, and everyone in the system has a ledger. When it comes to blockchain, everyone will mention Bitcoin, because blockchain is the underlying technology of Bitcoin and is mainly used in Bitcoin. Blockchain is like a large database ledger that records all transaction records. , and the updated accounting content will be sent to all system class users.
What is blockchain technology
In layman’s terms, blockchain technology is a way for all people to participate in accounting. All systems have a corresponding database. If the database is compared to an account book, then the person who keeps the accounts is very important. These databases currently keep their own accounts. For example, Alibaba is responsible for the Taobao account book, and WeChat is responsible for the accounting. The ledger is kept by Tencent. But in the blockchain system, everyone has the opportunity to participate in accounting. The system will select the person with the best and fastest accounting, record his content on the ledger, and send the content of the ledger to everyone in the system. Personal backup allows everyone to have the same ledger, ensuring that the accounting process is transparent. There is no central ledger, which greatly improves security. In the past, it was difficult for two parties who did not trust each other to conduct transactions. For the security of transactions, a third-party platform was needed, and blockchain technology solved the credit problem of user transactions. People can complete transactions without a third-party intermediary. Bitcoin The underlying technology of currency transactions uses blockchain technology, so many people associate Bitcoin with blockchain. It is precisely because Bitcoin has been very stable for many years that people pay attention to its underlying technology. People abstract the underlying technology of Bitcoin and call it blockchaintechnology.
I. The underlying technology of digital currency
In a nutshell, the underlying technology of digital currency is blockchain technology, which is essentially an electronic contract based on cryptographic algorithms. Whether it is the consensus algorithm, fault-tolerant algorithm, encryption technology, transmission technology, and storage technology that form the core of blockchain technology, they are all built on a complete cryptography foundation, not engineering technology. For this reason, blockchain technology does not rely heavily on physical infrastructure. In the most extreme cases, a simple blockchain network can even be built with the help of simple radio technology. In a broad sense, Bitcoin is only a specific implementation form of blockchain technology. As long as it has the core elements of decentralization, network-wide consensus, anti-tampering, and traceability, it can be regarded as a blockchain technology concept. extension.
J. What are the key points of the underlying technological innovation of the blockchain
Hello, I am very honored to answer your questions here. The following are some of my opinions on this issue. If there are any mistakes, please point them out. 1. The so-called blockchain technology, referred to as BT (Blockchain technology), also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records .
2. Blockchain is an innovative application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm in the Internet era. In recent years, the development and application of blockchain have had a profound impact on technology. Innovation and industrial revolution are of great significance. This experience introduces relevant knowledge of blockchain technology.
3. Blockchain is a distributed ledger that can contain financial and/or non-financial transactions, replicated (distributed) across multiple systems in near real-time through a peer-to-peer network, and each participant "owns" the same Having a copy of the ledger and getting updates as any transactions are added, each participant helps determine the inherent "immutability" of all existing records, using cryptography and digital signatures to prove identity, authenticity and enforce read/ With write access, there are mechanisms that make it difficult to change the history and can easily detect someone trying to change it. Thank you very much for watching patiently. If it helps, please adopt it. I wish you a happy life! Thanks!
