A. In the information age, what are the advantages of Shiduoli blockchain + copyright?

(1) Improve copyright registration efficiency and reduce copyright registration costs. According to relevant data , the fee for copyright of works starts from 100 yuan, and 300 yuan for works with more than 10,000 words. For short video works, the cost is obviously higher. The use of Shidoli's blockchain technology greatly reduces time costs and certification fees are relatively low.
(2) Safe, reliable and efficient rights protection At present, the use of blockchain technology to confirm the rights of cultural and creative works and as evidence in infringement lawsuits has gradually begun to be applied in my country’s judicial practice, because blockchain effectively guarantees the authenticity of evidence. Authenticity, legality and relevance, and the Shiduoli platform has patented authentication technology, which is more professional and reliable.
(3) Improve the value of cultural enterprises and help cultural enterprises in financing the confirmation of original works on the blockchain. While helping people establish copyright awareness, it also increases society’s recognition of the value of cultural enterprise copyrights and enhances corporate value. . In addition, for cultural enterprises with fewer fixed assets, the increase in the value of the copyright owned by the enterprise will help financial institutions recognize the enterprise's assets and promote the financing of cultural enterprises.
(4) Facilitate judicial evidence and reduce copyright disputes. Based on the copyright platform on the public chain, whether it is the submission of the author's work, subsequent transactions, or user purchases, there are corresponding timestamp certificates and are recorded on the chain. Open and transparent. In the case of copyright disputes, the judicial department only needs to trace the copyright based on the digital identity ID, and easily retrieve the historical transaction information of the copyright of the work, making it simple to provide evidence. On an open and transparent public chain copyright platform, copyright disputes will be greatly reduced. In the context of vigorously developing the digital economy, an environment with copyright protection can better attract the release of high-quality original visual content, thus driving the improvement of social value. In the transaction process, it can help multiple participants such as original creators, content providers, content platform distributors, and digital content disseminators to realize automatic distribution of income according to consensus agreements, balance the interests of all parties, and promote the construction of a good video copyright trading ecosystem.
Shiduoli better realizes the flow and realization of the value of video content copyright, and realizes the maximum value of originality. In the future, we will make its video copyright system more perfect.

B. How to define blockchain and what are the application scenarios of blockchain?

Many people now think that blockchain is a universal technology that can do anything. Blockchain technology is a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.

Definition of Blockchain: Narrow VS Broad

As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.

Blockchain technology features include:

Blockchain is a network distributed around the world. A database storage system that can operate collaboratively is different from traditional database operations - read and write permissions are in the hands of a company or a centralized authority (centralization characteristics). Blockchain believes that anyone with the ability to set up a server can participate. . Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).

At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.

At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.

As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.

Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.

Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.

Digital currency

After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the advantages of easy portability and storage, low circulation cost,It is convenient, easy to prevent counterfeiting and management, breaks geographical restrictions, and can be better integrated.

Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.

my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.

Financial asset transaction settlement

Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track on-chain transactions and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance processes are long, costly and complex. Blockchain technology can weaken the role of underwriting institutions and help all parties establish a fast and accurate information exchange and sharing channel. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Digital Government Affairs

Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. Tax department launches blockchain electronic issuanceWith the "Tax Chain" platform for invoicing, the tax department, invoice issuer, and payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing upon transaction" and "immediate reimbursement upon invoicing" - invoicing in seconds and reimbursement in minutes. , significantly reducing tax collection and administration costs, and effectively solving problems such as data tampering, over-reporting of one vote, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.

Evidence-based anti-counterfeiting

Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.

Data services

Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.

The three words "blockchain" were completely ignited during the Spring Festival that just passed. The limelight overshadowed everything. Some people said that this was the arrival of a new era. The past It has become a classic, and some people say that it is all hype and is ultimately a bubble.

In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, third-party electronic signatures haveTaiwan eShanbao revealed the latest progress of blockchain applications to NewSeed.

Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.

Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.

eShanbao’s new intellectual property protection solution based on timestamp + blockchain starts from the user’s real-name authentication and solidifies the information generated during the real-time solidification process. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.

Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.

Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.

From a technical perspective, blockchain is not a brand-new technology, but a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.

Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. Data authenticity, security and openness issues in the fieldBy establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Share

Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.

The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered can ensure the data flow process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness

"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.

Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding enterprises

Promote the rationalization of electronic guarantee rates

At present, the electronic bidding deposit guarantee guarantee letter It has been used to some extent in the field of bidding and bidding, and has solved the problem of capital occupation in bidding deposits for bidding companies. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.

At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .

Promote financial services for bidding companies

The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.

Solve the financing problems of successful bidders

Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.

Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. There is a risk of order and contract fraud under the traditional paper-based modelThe process is risky and cumbersome, and centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data credibility but also reduces the risk of corruption. The entire system relies on a centralized authority.

Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it possible to discount and finance. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; value transfer through the blockchain has greatly shortened the financing cycle; reducing supplier loan costs will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.

Regarding blockchain, we can imagine a decentralized management model and technical processing method.

Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.

So, you and your family discuss it together and simply use voting to solve the problem.

Then this way of voting to solve problems can be called the most elementary blockchain.

Decentralization solves problems.

What application scenarios can blockchain have?

In fact, many of our families and many organizations use blockchain management forms every day

However, this kind of blockchain application for organizational relationships cannot produce Economic Value.

What are the economic applications of blockchain?

The first type is used for tax deposit certificates, bank transfers, etc.

Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time

The second type is applied to enterprise operation and management

Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.

Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.

The characteristics of blockchain are distributed accounting and decentralization.But the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.

Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.

In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.

At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.

Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.

The most popular application industry at present is the financial industry.

An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since digital advertising traffic fraud causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud

In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode

What is blockchain

If you explain blockchain in non-technical terms, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.

What can the blockchain do?

If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:

Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.

If there are any deficiencies, please comment and correct them..

In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.

The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.

Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.

In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.

1. Cloud storage

This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?

Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15,728.64 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.

2. Medical aspects

Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.

C. How to apply blockchain How to apply blockchain

1. Financial field:

Blockchain It has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby quickly completing transaction payments while greatly reducing costs.

2. Internet of Things and logistics fields:

Blockchain can also be naturally combined in the fields of Internet of Things and logistics. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

3. Public service field:

Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields, but the centralized nature of these fields also brings Some problems can be solved using blockchain. The decentralized, fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network, and can be used to ensure that the operating system and firmware of an important infrastructure are not Tampered, you can monitor the status and integrity of the software, detect bad tampering, and ensure that the data transmitted by systems using IoT technology has not been tampered with.

4. Digital copyright field:

Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the ownership of works. Authenticity and uniqueness. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection. For example, MineLabs, a startup company in New York, USA, has developed a blockchain-based metadata protocol. This system called Mediachain uses the IPFS file system to realize copyright protection of digital works, mainly for copyright protection applications of digital pictures.

5. Insurance field:

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims. A typical application case is LenderBot, which was launched in 2016 by blockchain companies Stratumn, Deloitte and payment service provider Lemonway. It allows people to register customized micro-insurance products through the chat function of Facebook Messenger, providing services between individuals. The high-value items exchanged are insured, and the blockchain replaces the third-party role in the loan contract.

6. Public welfare field:

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

D. Application aspects of blockchain

The main application scope of blockchain includes: digital currency, financial asset transaction settlement, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields . Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain bookIt is essentially a multi-party participation, joint maintenance, and continuous growth distributed database system that applies cryptography technology. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission.Lose and wait. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. Government projectsThere is a certain degree of information opacity in bidding, and companies also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with, and can ensure the transparency of information, forming a shared trust among competitors who do not trust each other. And it can arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

E. If Station B invades the blockchain, can it give birth to a new world for young people?

Yuan Under the cosmic craze, another heavyweight player has entered the game.

Since the concept of the Metaverse has become popular in 2021, AR, AI, big data, cloud computing, games, social networking and other fields have become the intersection to the Metaverse, and Station B has chosen blockchain.

On December 6, Jiemian News learned that Station B is internally testing the Metaverse-related business "High Energy Chain" and has launched a block browser tool to query information on the chain. Bilibili believes that "High Energy Chain" is a digital native community built for new applications, culture, games and digital assets, and will support community governance in the future.

Regarding more specific questions such as "Is the underlying technology of the high-energy chain a public chain or a consortium chain?" and "when will it go online?", Station B stated that there is currently no more information to disclose.

But according to Tech Planet, the screenshots released during the internal testing of Station B’s “High Energy Chain” provide a wealth of information.

First of all, the Chinese name of "High Energy Chain" is easily reminiscent of Station B's classic barrage "High Energy in the Front". However, its English name does not correspond to it, but a new word "Upowerchain", which clearly emphasizes the concept of "empowerment".

This is also reflected in the vision of High Energy Chain. According to the screenshot, the vision of High Energy Chain is to "provide digital asset on-chain channels, welcome diversified applications to join the ecosystem, realize cross-application circulation of digital assets, and provide Users provide diverse usage scenarios and display stages. It becomes the 'sovereign identity authentication' + 'asset library' of organizations or individuals."

Corresponding to the concept of the metaverse, the core logic of the high-energy chain is technically To "empower" the residents of the Yuanverse and provide an ecological display platform. That is, blockchain technology is used to provide the identity authentication and asset accounts required by future digital residents (residents in the Metaverse), similar to ID cards and bank accounts in the real world. At the same time, a display platform is provided, corresponding to the "Moments" and "Facebook Home Page" in the real world.

Secondly, according to the screenshots, there are three application scenarios for the high-energy chain of Station B, namely "digital collections", "digital identity" and "digital world".

“Digital Collection” is now a popular “NFT”", a non-homogeneous digital certificate that can technically prove the ownership of digital content and assets. Blockchains owned by Alibaba and Tencent have launched this function this year. "Digital identity" is related to the blockchain It is related to the address of the chain. This is the prerequisite for everyone to use the blockchain, that is, they need an identity certificate and account address to represent themselves. The digital identity, identity information and other data created for users through blockchain technology are permanently stored on the chain. The ownership of the data belongs entirely to the user.

In terms of digital identity, the current mainstream technical solution in the domestic alliance chain ecosystem is to generate a unique string of blockchain hash values ​​based on the real-name information submitted by the user. , thus representing the user's unique address, but the user himself does not control the "private key" of the account (the private key is the proof of ownership of the blockchain address). It is reported that the Bilibili High Energy Chain has also adopted the same solution and will centrally manage it on behalf of the user Private key.

The "digital world" is the space where users can most directly experience the charm of the "metaverse". Station B defines it as a "new generation" digital world and marks "Coming soon." ". This also means that this "digital world" is not the virtual space in "Ready Player One", because current hardware technology is not yet able to realize such science fiction and movie scenes on a large scale.

And including virtual Cats and digital identities are currently mature technology scenarios. It is worth noting that another demonstration scenario of the high-energy chain is to support the interaction between users and idols. It is currently unclear whether it will be a virtual space like the game "Minecraft" Not sure.

The currently known technical information of Bilibili High Energy Chain as a blockchain platform is as above. From the response of Bilibili, it can also be predicted that the more familiar NFT will be the core implementation scenario.

In fact, it is not new for large technology platforms to deploy blockchain. Since 2015, Alibaba’s Ant Chain, Tencent’s Zhixin Chain, JD.com’s Zhizhen Chain, etc. have been launched one after another. has its own application scenarios. But among so many players at present, Bilibili may be one of the most noteworthy.

First of all, Bilibili has laid out the blockchain business "High Energy Chain" from the perspective of the metaverse. ”, whether it is catering to capital needs or media hot spots, when current hardware technology is still unable to realize “realistic” metaverse scenarios on a large scale, some ecological scenarios that have been implemented in the blockchain such as NFT (non-fungible tokens) , DeFi (Decentralized Finance), and DAO (Decentralized Autonomous Organization) may be the scenarios closest to the underlying concept of the Metaverse.

Some of the characteristics of Station B determine that it is the most suitable for China Be one of the technology platforms of the Yuanverse. Chen Rui, chairman and CEO of Bilibili, has a clear understanding of this.

In the phone call after Bilibili released its third quarter financial report for 2021 not long ago At the meeting, Chen Rui emphasized a point of view, “I think that in the concept of the metaverseThere is a very important thing here, that is, it needs a self-circulating content ecology. I think the concept of the Metaverse and the products it talks about cannot be completed by one company, because no company has such content production capabilities that can produce a world. Therefore, in this product system, there must be a large group of people who deeply create content and be able to profit from the content they create in this system. ” Chen Rui said.

There are only a few domestic super-large technology platforms that meet the standards of what Chen Rui calls a self-circulating content ecological platform, including Bilibili, Douyin, and WeChat.

/> First of all, from the perspective of the user scale and composition of Station B, according to the latest quarterly financial report of Station B, in the third quarter of 2021, the monthly active users of Station B reached 267 million, and the daily active users reached 72 million. And the main force of such a large-scale user The members are all from the "Z generation". Chen Rui, chairman and CEO of Bilibili, once said that the average age of Bilibili users is around 21 years old, and the average age of new users is around 20 years old, representing a large influx of post-00s.
< br /> So does such a large young population mean huge potential for "consumption power"? Perhaps what is more important is not the consumption potential, but the dwell time, which is also known as the "attention economy". No matter what it is The form of the metaverse, as a new virtual space, the most common thing between it and the real world is time, that is, everyone only has 24 hours a day. The longer you live in the metaverse, the shorter the time in real life is. Time is Fixed non-renewable resources. At this point, there is a resource conflict problem between the metaverse and the real world.

And "Generation Z" may be the generation that lives online the longest among all current generations. According to According to the latest public data of Station B, the average daily online time of users of Station B has reached 88 minutes, a record high. Obviously, the concept of the metaverse can only be established if users are willing to invest more time.

Secondly, the content creation system of Bilibili is one of the best implementation scenarios for NFT.

According to Yikai Capital’s "Metaverse Report", NFT is the main application of blockchain in the Metaverse world. One of the applications that can effectively support the economic system of the Metaverse. The latest data shows that the current NFT market size has exceeded 40 billion equivalent US dollars, and there are 600,000 users on OpenSea alone. Yikai Capital believes that the scale of the NFT market is unlimited, and in the real world Pan-digitization has taken shape.

At present, Tencent and Alibaba are one of the largest NFT issuance platforms in China. This year, Alibaba’s Alipay launched the mini program Ant Chain Fans, and Tencent launched NFT transactions. The magic core of the platform. But Alibaba’s main business is e-commerce, and Tencent’s core business is social + games. The three core elements of NFT are creators and cultural IP, technical support and platform publishers, community communication andcollector.

But from the actual development point of view, Alibaba and Tencent currently start from the middle technical support side, relying on their communities and users to provide collectors and display platforms. But the most core creators and IPs come from external cooperation. The first phase of Ant Chain NFT came from cooperation with Dunhuang Research Institute, and the first phase of Tencent cooperated with "Thirteen Invitations". When publicly introducing the development of NFT recently, Ant Chain has obviously accelerated its pace of signing creators and acquiring IP.

The main application scenario of Bilibili is the video content platform, and short videos can naturally be made into NFTs, which is a feature that Tencent and Alibaba’s NFT distribution platforms do not have.

Among the core elements needed for NFT, Bilibili itself has a large number of creators and users who love cultural creation, as well as a large number of IP images unique to the two-dimensional culture, such as the avatar characters of Bilibili itself. 22" and "33". The Bilibili community itself is the most active two-dimensional community in China. Among the three core elements of NFT, Station B only lacks blockchain technology support.

In the third quarter of 2021, Bilibili’s PUGV (Professional User Generated Video) playback volume accounted for 93% of the total playback volume on the platform. The average number of active UP owners per month reached 2.7 million, and the average number of video submissions exceeded 10 million in the same month. Every video contribution by these users can theoretically be made into NFT, and NFT itself can also bring additional economic benefits to creators, and players can also unlock new consumption scenarios and participate in social communication, which Chen Rui emphasized The incentives for creators to produce coincide with each other.

Putting aside crypto art, the only products in China that naturally have such large-scale NFT video production resources and creator platforms are Douyin, Kuaishou and Bilibili.

Finally, from the perspective of community economy, Station B also has one of the prototypes of the metaverse. Due to my country's prohibition on virtual currency mining and trading, most domestic blockchains have blocked the economic system of "Token" in blockchain technology. However, Bilibili’s high-energy chain internal test clearly mentioned the words “digital assets” and “personal asset library”.

When it comes to this part, many people will notice the hype of cryptocurrencies led by Bitcoin, but in fact, in the blockchain system, "Token" is also a "token", not just a The economic system is also a governance system. In an online world, after everyone's identity is digitized, how to ensure that everyone has the right to express their personal opinions from a technical perspective? "Token" is a tool for expressing opinions, and each token means the right to vote. Users can express their preferences, opinions, and participate in the construction of the Metaverse itself.

“Coin” is currently the most important virtual currency of Station B.It is one of the fictitious items that can be used to support outstanding video works. This is an affirmation for the UP owner. The more coins the UP owner obtains, the more content creator incentives he can get from Station B. This is a direct economic benefit, and he will receive traffic support, which is a creative incentive. Therefore, coins have become one of the most coveted items for the creators of Bilibili, and the way to obtain them is to create better content to attract viewers to invest coins.

The production method of "coins" is for viewers to participate in the internal ecology of Bilibili, such as logging in every day, purchasing Bilibili members, participating in community activities, etc. B coins can only be purchased directly. It can be used to purchase paid dramas and reward your favorite UP owners.

It is not difficult to see that the "Token" system of Bilibili has already taken the prototype of the metaverse, that is, on the basis of meeting certain economic needs, it also plays a role as a governance tool. Users use it to express Based on their own preferences, creators can produce better works. Blockchain technology can allow this part to be completely completed by code. For example, Bilibili’s “high-energy chain” technology can fully maximize the community governance function of Bilibili’s coins.

Of course, the current concept of the metaverse encompasses too broad a concept. Each platform has different ideas on how to approach this concept. Facebook chose to change its name to "Meta" after losing money on cryptocurrency, and Microsoft By choosing the "Enterprise Edition Metaverse", Disney placed more emphasis on building its own offline + online super park, while Station B chose to start with the blockchain. With the overheated hype of capital, no one knows whether it is the future of mankind or a "bubble" that will eventually be punctured.

F. What is Blockchain Video

Blockchain is a distributed shared accounting technology. What it wants to do is to allow all parties involved to use the technology. Build a trusting relationship at all levels. 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. What is the core meaning of blockchain? Our understanding is that the core meaning of blockchain is to establish data credit among participants, and through unilateral confrontation, create a complete opportunity for unilateral ecological joint protection under clear regulations. , this is a system. This kind of establishment can end the problems before the blockchain. Before the blockchain, it was impossible to achieve new sharing when sharing data. Even if it was oriented, it would only give you an interface. After the blockchain is created, the participants can realize the sharing of credit.
Blockchain has been applied in several fields. In the first field of digital assets, in addition to some points and check-in cards we have seen, it also includes various other assets, and there is a process of asset digitization. For example, the tokens of different crowdfunding projects on the Biying China platform.

The second area is the field of trade finance. Because the field of trade finance is originally a multi-link and multi-party participation method, blockchain can greatly improve China’sThe efficiency of time makes many original products achieve the effect of substitutes.

The third area uses equity, which is company equity like some regional equity trading centers. The purpose is to facilitate equity-to-transaction and facilitate relative circulation. At present, the multi-center blockchain system can indeed improve efficiency and reduce costs.

G. What are the applications of blockchain technology?

Blockchain has become so popular, so what are the application fields of blockchain?

At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency.

Financial institutions are the most willing to explore blockchain applications and need new technologies to improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If the application of blockchain in the financial field is verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to digital currency applications, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.

As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain" is becoming a reality.

(1) Blockchain medical care: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health (EHR), DNA wallet, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.

(2) Blockchain Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things with blockchain technology Application will become a very important application field.

(3) Blockchain IP copyright & cultural entertainment: Since the Internet became popular, digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain features disintermediation, consensus mechanism, and non-tamperability. Blockchain technology can be used to integrate all aspects of the cultural and entertainment value chain.It can effectively integrate, accelerate circulation, and shorten the value creation cycle; at the same time, it can realize the value transfer of digital content, ensure the credibility, auditability and transparency of the transfer process, and effectively prevent piracy and other behaviors. Blockchain Public Services & Education: In the fields of public services, education, closed-door charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on third parties with credibility. The company makes credit endorsements, but problems such as fraud and deficiencies still exist.

H. The development status of the global blockchain industry in 2021 is based on both the global perspective and the domestic perspective

As an emerging information technology, blockchain will continue to develop in-depth in 2021 , there have been continuations and breakthroughs in regulatory policies and applications, and related NFT, metaverse and central bank digital currencies are ushering in an explosion.

In the era of digital economy, it is particularly important to grasp the development and development trends of blockchain. This article will start from two perspectives: a global perspective and a domestic perspective

(1) Global perspective: the blockchain industry is growing in leaps and bounds, and the track in emerging fields is hot

1. Blockchain has become a multinational strategy, and cryptocurrency policies are polarized

2. Blockchain spending grows, with banking industry spending leading

Blockchain and other distributed ledger technologies have shown great potential in improving the efficiency of business operations and creating new ways of delivering value, across industries and Companies are implementing these technologies and integrating them into existing infrastructure and industry plans. According to Statista, global spending on blockchain solutions is expected to reach $6.6 billion in 2021. Forecasts indicate that spending on blockchain solutions will continue to grow in the coming years, reaching nearly $19 billion by 2024

3. NFT, cryptocurrency, and the metaverse are booming

In 2021, new models and new business formats based on blockchain will continue to emerge. Among the hot words of 2021 announced by Collins Dictionary, NFT ranked first on the hot word list, and the words Metaverse and Crypto were also shortlisted for the list.

Starting in March 2021, NFT has experienced explosive growth. The full name of NFT is Non-Fungible Token, and the Chinese expression is non-fungible token. NFT is a data unit stored on the blockchain. It uses photos, videos, audios and other types of digital files as underlying assets, and supports the verification of the authenticity and uniqueness of the underlying assets.

4. More than 90% of the world’s economies are exploring central bank digital currency

(2) Domestic perspective: The blockchain industry is making steady progress, and the digital renminbi has achieved gratifying results

1. Promote the development of blockchain technology and rectify virtual currency transactions and "mining" activities

2. The number of registered blockchain companies continues to rise, and the industry is about to enter a "steady recovery period"

3. The digital renminbi is in full bloom, and three major challenges need to be overcome

I. What is blockchain technology What is blockchain in a popular explanation

Since the end of October, blockchain has been in On the cusp of the storm.

What is blockchain technology

Although blockchain has been around for more than ten years, many people still don’t know much about this technology.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. From an application perspective, blockchain is a distributed ledger.

So, why is the blockchain called the blockchain?

Because the blockchain itself is a series of linked blocks, these blocks are filled with transaction records. The blocks are much like the records of a database. Every time data is written, it is Create 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 technology?

Simply put, blockchain has the characteristics of decentralization, openness, non-tampering, and anonymity.

1. Decentralization:

In the blockchain system, there is no center.

In the blockchain model, it is distributed accounting and storage. Each node self-verifies, transmits, and manages information. Each node is the center, which is decentralization.

2. Openness:

The blockchain system has the characteristics of openness, the data is open, and anyone can query the blockchain data and data through the public interface. Develop related applications.

3. Information cannot be tampered with:

In the blockchain system, once the data is written, the tampering cannot be undone unless 51% of all data nodes are controlled. Forge a record that does not exist. Therefore, blockchain technology has a certain degree of security.

4. Privacy and anonymity:

The cryptography technology in the blockchain can effectively achieve identity concealment.

The identity information of each node does not need to be disclosed or verified, and information transfer can be done anonymously. It can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.

Xiao Li lent 10,000 yuan to Xiao Wang, and Xiao Li found twoWhat everyone has in common is Xiaobai to prove it. This accounting model is a centralized accounting model, and Xiaobai is the center.

However, a year later, when Xiao Li wanted to get the money back, Xiao Wang Shikou denied that he had lent him the money. It turned out that Xiao Wang introduced Xiao Bai's girlfriend to his company. a job.

This is the disadvantage of centralized accounting.

Xiao Li learned a lesson and gained wisdom. In the future, when someone asked him to borrow money, he said on WeChat in the village that I would lend so-and-so how much money. In this way, everyone in the village knew that Xiao Li How much money did Li lend to whom?

In this way, when Xiao Li asks for debt again in the future, the other party will not deny the issue, because a consensus mechanism has been established in the minds of the people in the village: How much did you borrow from Xiao Li? .

This is the advantage of decentralized accounting.

Because after all, there are many people to testify about this transaction. If it seems to be a fraud, it will be unless more than half of the people in the village are bought. However, the price is very high.

In fact, these characteristics of the blockchain are all to solve the problem of "trust". The rich application scenarios of the blockchain are also based on the blockchain's ability to solve the problem of information asymmetry. At the same time, Blockchain also helps achieve collaborative trust and consistent action among multiple entities.

What are the applications of blockchain?

In addition to digital currency, there are many application scenarios of blockchain.

1. Medical field

Blockchain helps realize smart medical care, such as going to the hospital to see a doctor. Through the blockchain model, the patient’s medical status, cases, treatment status, etc. are all Clearly visible, saving a lot of medical resources.

2. Copyright field

Blockchain can prove the authenticity and uniqueness of the copyright of works, from the birth to the transfer of audio, video, pictures, text and other works. Can be tracked and recorded, and form tamper-proof information.

3. Logistics field

After applying blockchain in the logistics field, goods can be traced from production to consumption.

4. Food safety

Is blockchain used for food safety? Through blockchain traceability, one can easily trace the past and present life of their food.

5. Securities trading

For example, traditional securities trading requires the coordination of multiple institutions to complete, while the blockchain system can independently complete one-stop transactions. This service can make securities trading simpler and faster.

However, many people have big misunderstandings about blockchain, and the biggest misunderstanding isYes: Blockchain = Bitcoin

In fact, blockchain and Bitcoin are not the same thing. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the third layer of blockchain. an application.
