⑴ What is blockchain technology? What exactly is blockchain? What is blockchain?

1. The so-called blockchain technology, referred to as BT (Blockchain technology), is also Called distributed ledger technology, it is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.

Explain in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as an accounting behavior. The principle of blockchain technology is to find out the accounting information within a period of time. The fastest and best person will keep accounts, and then send this page of information to everyone else in the entire system.

2. Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

(1) The characteristics of blockchain are used to develop new business formats. Extended reading:

The blockchain system consists of a data layer and a network layer. , consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms.

The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the The basis of the chain's programmable features; the application layer encapsulates various application scenarios and cases of the blockchain.

⑵ The main features of the blockchain business model are

The blockchain distributed business model has the following characteristics:

1. Dimensionality reduction

The traditional business model is high-dimensional and has extremely asymmetric information. For example, automobile manufacturers shield the cost and technical content of car manufacturing from customers, and companies obtain profits through information asymmetry. The Internet business model is mid-latitude. The platform controls all user information and all stakeholders are related on the platform. The platform seems to be fair to everyone, but in fact different users have different information and permissions.

The blockchain distributed business model is a low-dimensional one, which significantly reduces the dimensionality of the Internet and traditional business models. It is specifically realized as information symmetry, openness and transparency, equal power, removal of centralized platforms, and all users All transactions occur on the same level. For example, Alipay is an Internet business model.The Alipay platform holds the information of hundreds of millions of users, and all transactions must be processed through the Alipay settlement center. Alipay has the right to intervene in abnormal transfers it determines, and has the right to modify the rules and charge relevant fees according to the set rules, while users can only passively obey . The relationship between Alipay and users is one of centralized power and obedience. The Bitcoin network can be understood as the parallel migration of the Alipay system on the blockchain. It is a decentralized point-to-point payment system. In the Bitcoin network, there is no centralized settlement system. Settlement and accounting can only be completed with the participation of all nodes. Its rule transactions are solidified by code, information is open and transparent, and node participation rights, accounting rights, and income rights are all are equal and characterized by high trust. The relationship between the Bitcoin network and each node is complementary and indispensable. If the Bitcoin network leaves node verification, the payment system cannot operate.

2. Distribution

Dimensionality reduction solves the unequal relationship between the original centralized organization and users, but once the dimensionality is reduced, a huge number of users will How (node) relationships are handled is the core of the blockchain business model. In a distributed network where everyone is the center and everyone is a node, obtaining benefits through fair competition on the basis of equal rights and responsibilities is in line with the characteristics of extreme competition in the market. For example, in the Bitcoin network, every node has equal power and competes fairly to obtain Bitcoin rewards based on POW. In the commodity traceability system, every node is an equal member, information is not controlled by any party, power is equal, and responsibilities and interests are clearly divided.

Distribution of power has an motivating effect in business models. Unfair competition is prone to occur in traditional business models and Internet business models, thus damaging the enthusiasm of entities to participate. For example, in the auction market, due to opaque information, it is difficult to avoid power rent-seeking and collusion. In the blockchain network, each node exists in a distributed manner and competes in an information-transparent environment. Therefore, the blockchain distributed business model is a model that conforms to the laws of the market, which can promote the market mechanism and improve the incentive effect of the market.

3. Equity decomposition

Equity decomposition may be the biggest innovation in the blockchain distributed business model. Generally, ownership includes four rights: possession, use, income, and disposal. In the traditional business model, property rights transfer generally includes the transfer of these four rights together, while property rights leasing only transfers the right to use, and the owner retains the rights of possession, income and disposal. Ownership and management rights may or may not be separated, and the separated management rights are in the hands of specific operators. In the Internet business model, ownership has begun to differentiate significantly. Users enjoy the right to use a large number of Internet products, but do not have the right to possess, benefit or dispose of them. Management rights have little to do with users, and only a small number of crowdsourcing products (***) are relevant.

In the blockchain distributed business model, ownership, use, and income, The degree of separation of disposal is large, and the degree of separation of ownership, management rights, and decision-making rights is large, and the management rights and decision-making rights (partly) are in the hands of ordinary users. In the Bitcoin network, those who hold Bitcoins enjoy the rights to the future income of Bitcoins, but do not have the right to possess them. The nodes control the settlement rights and accounting rights, and the blockchain network cannot leave the participation rights of the nodes. A more specific example is that investors purchase stocks and enjoy the equity of the listed company, including the rights of possession, use, income and disposal, but they have no operating rights, and most of them have no decision-making rights. When investors purchase currency, they do not have ownership of the project, but they have the right to future income from the currency, as well as the right to use and operate as a node (verification and accounting rights), and voting rights (decision-making rights). Of course, there are still many problems in the current rights, responsibilities and interests system. In many blockchain projects, the rights and interests of many blockchain projects cannot be guaranteed because investors have no ownership rights.

This decomposition of rights and interests leads to changes in the original relationship of rights, responsibilities and interests, thus forming a new business model. In the distributed business model, project owners, operators, decision-makers, users, and beneficiaries are separated from each other and at the same time interdependent. The ideal state may be that the beneficiary (coin holder) takes higher risks and makes profits through the money market, and the owner profits from the project profits, but the beneficiary reduces the income risk by participating in operations and decision-making.

The blockchain distributed business model still has a lot of room for development, the most critical of which is how to build a standardized currency market to protect the interests of the beneficiaries. In this way, in this business model, risks can be transferred, income distribution can be benign, and rights, responsibilities, and benefits can be more clearly defined.

⑶ What industries are blockchain suitable for?

Industries suitable for blockchain include financial industry, copyright protection, traceability and anti-counterfeiting, energy industry, sharing economy, Internet of Things, etc.
my country’s blockchain industry has developed over the past ten years. Basically, a relatively mature industrial chain has been formed. Under the conditions of national policy promotion and increasing demand in downstream application fields, the market size of my country's blockchain industry continues to develop, with high geographical concentration and obvious industrial cluster effects.
With the increasing maturity of blockchain technology, the blockchain industry is entering the 3.0 stage as a whole, with good performance in finance, logistics, copyright protection and other fields. In order to promote my country's digital construction, accelerate The Digital China process has made a huge contribution.

⑷ How to define blockchain and what are the application scenarios of blockchain?

Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. 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 fields of blockchain technologyScenarios naturally need to be combined with the characteristics of blockchain that are different from other technical systems.

Blockchain technology features include:

Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). 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 of the digital economy era.direction. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.

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 transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. 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. BlockchainInvoices are the earliest application of blockchain technology in China. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, 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 developed as early as the past two years.It has begun to be applied to many industries, such as electronic signatures. Recently, the third-party electronic signature platform 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 in the process in real time. 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", "tamper resistance", and "openness and transparency",Blockchain technology can effectively solve the problems of data authenticity, security and openness in the data field. By establishing a trustworthy data management environment, it can prevent and avoid various data management problems such as data fraud, tampering and loss, and promote data efficiency. Share and apply. 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 with can ensure the data circulation 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 bidding corporate financial services and corporate financing

Promote Rationalization of electronic guarantee rates

At present, electronic bidding deposit guarantees have been used to some extent in the field of bidding, solving the problem of capital occupation of 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.

Solving 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 and national enterprises and institutions. The winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a premium.Apply for a loan from a financial institution with pledged assets. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. 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 trustworthiness 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 discountable and financing. 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; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which 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 traffic fraud in digital advertising 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 happens to be able to reallyis doing just that.

If there are any deficiencies, you are welcome to comment and correct me.

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 15.72864 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.

What is the blockchain? Many people have no idea about the blockchain. It is not very clear what the chain is, and some people have even never heard of it. In fact, blockchain is a common one. I have compiled relevant information about what blockchain is for everyone.

What is blockchain 1

Speaking of blockchain, we have to mention its twin brother-Bitcoin.

Time goes back to 11 years ago. On November 1, 2008, the world was shrouded in the huge shadow of the financial crisis. That day, a mysterious geek who called himself "Satoshi Nakamoto" sent a group email.

Attached to the email is a paper titled: “Bitcoin: A Peer-to-Peer Electronic Cash System.”

Satoshi Nakamoto said in the email that he is working on a new electronic cash system that is completely peer-to-peer and does not require any trusted third party. About half a month later, Satoshi Nakamoto released the source code of the Bitcoin system non-stop.

On January 3, 2009, an interesting invention turned out. Satoshi Nakamoto generated the first Bitcoin block on the server, which is the so-called "Bitcoin genesis block". Since then, the Bitcoin system has officially opened.

Having said that, you might as well stop and think about how we conduct cash transactions in real life.

Suppose you borrow 10,000 yuan from a friend and promise to pay it back in one month. You may choose to repay the loan by bank card transfer. The bank is responsible for deducting 10,000 yuan from your deposit account and adding 10,000 yuan to your friend's deposit account.

Here, the bank is the institution responsible for keeping accounts. The underlying reason why you choose bank transfer is that you believe it is more reliable and will help you transfer 10,000 yuan to a friend.

However, in the digital world, inventing a currency is another matter.

The hero behind the Bitcoin game

First of all, Satoshi Nakamoto hopes to conduct peer-to-peer direct transactions, bypassing the third party of the bank. This problem is easy to solve. Then there will be no banks. Users will issue their own currencies through a unique mechanism and trade directly with each other.

But this brings another problem. There is no bank as a reliable intermediary responsible for accounting, and users do not know each other. How to ensure that no one cheats during transactions?

For example, in the digital world, electronic files can be easily copied. 10 yuan of digital currency turns into 100 yuan by copying and pasting it with the mouse 10 times. Isn’t it a mess?

To solve this problem, we need to provide a mechanism for everyone to trust each other.

The method adopted by the Bitcoin system is to record all transaction processes openly and transparently in chronological order. These records are permanent and cannot be tampered with. This way you won't be able to do anything sneaky.

With these mechanisms, the Bitcoin system operates successfully.

This system stores data in units of data blocks, which are blocks. Approximately every 10 minutes, new blocks will be added. Each block records the detailed transaction process of Bitcoin and is timestamped. Different blocks are connected in chronological order through a certain algorithm, which is a chain.

Together, they are called "Blockchain".

In this way, the blockchain took root with the birth of Bitcoin. If Bitcoin is the star in front of the spotlight, blockchain is responsible for providing trust in the underlying technology.The unsung hero of the mechanism.

Brand new changes in accounting methods

Although behind the scenes, the talent of blockchain was quickly discovered.

In technical terms, blockchain is a distributed ledger technology. To understand it, let’s take the simplest example.

Suppose your family keeps accounts like this: you, your father, and your mother each have an account book. You each record your own expenses, and at the end of each month, you tally the total household expenses together.

But dad likes to buy cigarettes, mom likes to stock up on cosmetics, and you like to buy snacks. You may both miss a few entries intentionally or unintentionally, and sometimes make corrections in the ledger. Therefore, when checking the accounts at the end of the month, there is always a discrepancy with the actual expenditure of the family.

In order to change this situation, you bought a new account book. You, your father, and your mother jointly use a new account book to keep accounts, remind and supervise each other, and check every expense together.

At the same time, you also agreed that once the expenses are clearly recorded, no alteration or deletion is allowed. After trying it for a few months, you found that this joint ledger matched the actual expenses of the family much more closely.

Blockchain is the second accounting method. The little story above tells us that it has at least these major features or benefits.

First of all, it is decentralized. The database that was previously maintained by one party has become jointly maintained by multiple parties. Everyone writes data together based on consensus, and no one can control the data alone.

Secondly, it allows everyone to change from keeping separate accounts to joint accounting, which brings consistency and openness and transparency to the data.

In addition, the blockchain only allows data to be written, not deletion or modification, which prevents data from being secretly tampered with.

Mutual trust between strangers

In reality, many scenarios are much more complicated than how to keep accounts at home. Moreover, many aspects of financial transactions and business processing are mostly operated by strangers. How can we make everyone trust each other?

It’s blockchain’s turn to show its talents. Don’t forget, it can provide a mechanism for everyone to trust each other from the underlying technology.

For example, when you usually go to the wet market to buy things, you may worry about whether fish, shrimp, and vegetables are safe. Some companies see business opportunities and move the data of farmers and fish ponds to the blockchain. In this way, you will know which fish pond the fish you buy comes from, and you will feel more confident when eating.

For another example, links to fundraising for seriously ill patients often appear in Moments. When making a donation, you may have some concerns: Is the patient's condition real? Can donations really be delivered to patients?

In order to eliminate these concerns, some Internet charity organizations use blockchain to allow you to clearly view the steps for using your donation. If the review finds that the patient's condition is not true, the blockchain system will automatically return the donation to your account.

In the future, what changes can blockchain bring to our lives?

It is conceivable that when blockchain is widely used in various fields of society, it will become an important infrastructure in the information age and can solve many of the headaches that currently cause us.

For example, blockchain will allow countless islands of information to be "chained" together. When seeing a doctor, there is no need to repeat the examination just because you change hospitals. Entrepreneurs do not have to go to multiple departments to go through a procedure; many transactions no longer need to be done. Third-party guarantees are required, consumers no longer have to worry about non-refundable deposits, and creators do not have to worry about their works being stolen but getting nothing...

What is blockchain 2

From an academic perspective, blockchain is New application models of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Blockchain is essentially a decentralized database.

Many people still don’t understand this explanation, so let me make a simple metaphor.

Hypothetical situation: Suppose you have a ledger at home and you are asked to keep accounts. In the past, your parents gave you your salary and asked you to record it in your account book. If you are greedy and want to buy something delicious in the meantime, the record in the ledger may be less than ten yuan.

This is just an example. I believe that when we were children, everyone probably wanted to take some money from their parents’ pockets to spend.

Ways to use blockchain to solve problems:

If you use the whole family mobilization method to keep accounts, the above-mentioned problems will not exist, because you are keeping accounts, and your father They are also keeping accounts, and your mother is also keeping accounts. They can all see the general ledger. You can't change it, and neither can your parents. So your father who wants to buy cigarettes and you who want to eat have nothing to do.

Functional "blockchain"

It can not only record every transaction, but also can be programmed to record almost everything of value to mankind. Things: birth and death certificates, marriage licenses, title deeds, degrees, financial accounts, medical history, insurance claims, ballots, food sources, and anything else that can be represented by a code.

Each block is like a hard disk, which saves all the above information and then encrypts it through cryptography technology. The saved information cannot be tampered with.

Every 10 minutes, the blockchain system will check all data generated during the period (such as transaction records and records of when the block was edited or created, etc.) and store these data in a new area. On the block, this block will be connected with the previous block to form a chain. Each block must contain relevant information from the previous block to be effective.

Characteristics of blockchain

1. Exceptionally safe:

Unlike centralized databases owned by companies or government agencies, blockchain is not controlled by anyone. or entity's control, data is replicated (distributed) in its entirety across multiple computers.

And setUnlike Chinese databases, there is no single entry point for attackers, and data security is more guaranteed.

2. Non-tamperability:

Once entered into the blockchain, no information can be changed, and even the administrator cannot modify this information.

Once something appears, it cannot be changed. This attribute is of great significance to the changeable and ever-changing online world that humans currently live in.

3. Accessible:

All nodes in the network can easily access information.

4. No third party:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so whether you are trading or exchanging funds, there is no need for a third party of approval.

Blockchain itself is a platform.

Blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each is keeping its own account.

Since there is no centralized intermediary agency, letting everything run automatically through preset programs can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.

Blockchain technology is the underlying technology of Bitcoin. Without the operation and management of any centralized organization, Bitcoin has been running very stably for many years without any problems, so some people have noticed its The underlying technology abstracts the Bitcoin technology and calls it blockchain technology, or distributed ledger technology.

According to a report released by Santander, Spain's largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.

Cloud computing is usually defined as providing dynamic, easily scalable and often virtualized resources through the Internet, but it is often a centralized organization that provides a cloud computing platform. The network composed of blockchain generally does not have a specific organization, so blockchain is closer to the definition of a distributed computing system and is a type of distributed computing.

The future development and application scenarios of blockchain

1. Digital identity

Many people will encounter "prove that my mother is me" when applying for various certificates. "Mom" dilemma, with blockchain, you no longer have to worry about it.

It turns out that our birth certificates, real estate certificates, marriage certificates, etc. need a central node for everyone to recognize them. Once cross-border, contracts and certificates may become invalid because of the lack of a global central node.

The non-tamperable nature of blockchain technology has fundamentally changed this situation. Our birth certificates and real estate certificates, marriage certificates can be notarized on the blockchain and become something trusted by the world. Of course, it can also easily prove that "my mother is my mother."

2. Health care

Simply put, it is to use the blockchain to establish a universal record repository with timestamps, so that different databases can extract data information.

For example, when you go to see a doctor, you don’t have to change hospitals for repeated examinations, and you don’t have to worry about reimbursement for medical insurance, which can save time and expenses.

3. Travel consumption

For example, we often use apps such as Ctrip and Meituan to find and place orders for hotels and other services, and each platform gets commissions from them.

The application of blockchain is to remove middlemen and create a secure, decentralized way for service providers and customers to connect and trade directly.

4. More convenient transactions

Blockchain can make payments and transactions more efficient and convenient. The blockchain platform allows users to create smart contracts that become active when certain conditions are met, meaning that automatic payments can be released when both parties to a transaction agree that their conditions are met.

5. Strictly control product quality

If you buy an apple, with blockchain technology, you can know the entire process from the production of the fruit farmer to the circulation link. Among them are government regulatory information, professional testing data, enterprise quality inspection data, etc. A smart supply chain will make the food we eat and the products we use every day safer and give us more peace of mind.

6. Property rights protection art

The creator puts his work on the blockchain, and if someone uses his work, he can immediately Know. Corresponding royalties are also automatically paid to the creator.

Blockchain technology not only protects copyright, but also helps creators sell their works to consumers better and more directly, without the need for the assistance of distribution companies.

What is blockchain 3

Advantages of blockchain

Decentralized, it does not require the intervention of a third party and enables point-to-point transactions, coordination and collaboration. Because the data is distributed in various nodes through algorithms and has a unique verification mechanism, no one organization or individual can control the global data. Since it is distributed in various nodes, any node stopping work will not affect the entire system. Operation, this decentralized network will greatly improve data security. The data in the system is jointly maintained by various nodes with maintenance functions.

Openness. In addition to the private information of all parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain through the public interface. Data and development related applications, so the entire system information is highly transparent.

The use of blockchain

Blockchain is an open, transparent, decentralized and secure technology. This technological revolution is applied to the Internet. For data-sensitive fields such as medical care, public opinion supervision, and ecological testing, it can prevent data from being tampered with and ensure the authenticity of the data.

In short, blockchain is not just a method of virtual currency, its advantages will play an important role in many industry fields

⑹ Application of blockchain< /p>

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, 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 is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. 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’s impact on the field of information security is reflected in the followingThree points:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of the blockchain will make hackers confused. Some companies have begun to develop distributed Internet domain names based on the blockchain. system, 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. 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 rental car is entered into the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, andThe blockchain updates information synchronously. It’s not just imagination, this type of process could become a reality for car sales and car registrations as well.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easier. Emerging blockchain 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 achieve this through blockchain. Equity transfer of private companies

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision, because blockchain technology can ensure the transparency and immutability of information. , which plays a great role in the implementation of transparent government management. There is a certain degree of information opacity in government project 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

⑺ What is blockchain technology and what areas may it be used for in the future?

What is blockchain technology? Blockchain is a distributed shared accounting technology that allows all parties involved to establish a trust 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 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.
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 the efficiency of the middle, making many of the original substitutes effective.
The third area uses equity, which is a company's equity like some regional equity trading centers. The purpose is to facilitate equity-to-transactions and facilitate relative circulation. At present, the multi-center blockchain system can indeed improve efficiency and reduce costs.
Xinlian is an information platform for news and data mining that is vertical in the field of blockchain. We hope it will be helpful to you.

⑻ In which fields is blockchain suitable for application?

The first one is the information security industry.
The second one is the bill business field
The third one is the payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the Proof of Stake blockchain can obtain a completeData recording, using the characteristics of reliability and collective maintenance of the blockchain, can confirm the rights of the owners of rights and interests.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.
