⑴ Only the new generation of infrastructure can create blockchains of various ages
The new generation of infrastructure is the most important opportunity for the current blockchain industry
In society In the field of economic and life, infrastructure is simply understood as the system that provides core public services for social production and residents' lives. These infrastructures are often advanced and basic. Without these, it would be difficult to carry out our daily production and life activities.
When the infrastructure usually reaches a certain scale, effective services can be provided. Objectively speaking, the blockchain industry is still in a very early stage, and the infrastructure is not yet mature. Therefore, based on Blockchain services, applications and business models often face difficulties in developing.
Although the new era of value Internet is coming, the pace of arrival is far from as fast as imagined. Blockchain is an industry that combines deeply to bring about changes. Finance and economy can currently be used in this field. The most important opportunity to have a huge impact is undoubtedly the construction of infrastructure, and the core issue that infrastructure needs to solve is the establishment of "standard issues." Rubber Band
In the early days of the Internet, there would have been no push for standards establishment by organizations such as IEEE and W3C. Internet protocols are difficult to unify, and the Internet will not develop rapidly around the world. In the future, the standard of blockchain will be similar to the Internet. It is not a protocol, but a set of protocols, and continuous improvements will be made. This kind of technology can be well applied in many industries and fields. As long as the information related to value has a natural affinity with the blockchain, it can be combined to develop new ways to better Meet the needs of different industries.
When it comes to the specific content of blockchain infrastructure, it is mainly divided into two categories:
One is the research and development and construction of blockchain. The blockchain here refers to are used for different purposes or in different industries. Various types of blockchain.
The other type is the connection facilities between blockchains. These facilities can realize the interconnection between different blockchains and allow the free flow of value.
Since the application scenarios of blockchain are very wide and different, with different needs, we cannot expect that one blockchain can solve all problems.
If a blockchain carries too many functions, it will become complex and unmaintainable, thus seriously reducing efficiency and reliability. In the same way, if a blockchain contains various types of data, the amount of data will be too large and decentralization will be seriously limited. Therefore, diversified blockchains will be an inevitable trend in future development.
The future complexity of blockchain,It is not reflected in any public chain, but in the hierarchical structure composed of blockchains. The infrastructure, refraction, and key point side chain technology that the hierarchical structure relies on are a typical connection facility. .
This concept was first proposed by Brax for the company, with the goal of building technology that allows digital assets to be freely transferred between different blockchains. They released a white paper on sidechain technology in 2014, and in The first commercial sidechain was released in early 2016.
Just like diversified blockchains, with the evolution and development of technology, the technical concepts and operating methods of future inter-blockchain connection facilities will also be diversified, diversified, and different. Various forms of connection facilities to meet different types of connection needs and build a true blockchain ecosystem.
⑵ What disruptions does blockchain bring and why can it become a national strategy?
The disruptive characteristics of blockchain lie in the following four aspects: 1. Transparency. The data records of the blockchain system are transparent to the entire network nodes, and the update operations of the data records are also transparent to the entire network nodes. This is the basis for the trust of the blockchain system. Since the blockchain system uses open source programs, open rules and high participation, blockchain data records and operating rules can be reviewed and traced by nodes throughout the network, with high transparency.
2. Openness. The blockchain system is open. Except for the private information of the parties directly related to the data, which is always encrypted, the blockchain data is open to everyone (except for blockchain systems with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the public interface, so the entire system information is highly transparent.
3. Information cannot be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for systems such as private blockchains with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high
4. Decentralization. Decentralization is the most basic feature of blockchain, which means that blockchain no longer relies on central processing nodes and realizes distributed recording, storage and updating of data. In a traditional centralized network, attacking a central node can destroy the entire system. However, in a decentralized blockchain network, attacking a single node cannot control or destroy the entire network or more than 5% of the nodes in the network. It's just the beginning of gaining control. 2019 is the first year of commercial application of blockchain technology, and favorable policy incentives will make the development of blockchain technology more stable.
As the application of blockchain technology gradually penetrates into many fields such as digital finance and the Internet, everyone has a clearer understanding of the value of blockchain.
Blockchain has formed a global competition situation, and all countries are seizing development opportunities, let alone China.can fall behind; therefore, it is understandable that blockchain has become a national strategy.
⑶ 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 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 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, those 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 data areaBlocks are connected in an orderly manner and are cryptographically guaranteed to be non-tamperable and non-forgeable distributed ledger (database) 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 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 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, IWe can establish an alliance chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers, and the bills can be transferred between suppliers after being digitized on the chain. Level suppliers can obtain financing of the corresponding amount with digital bill certificates.
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. 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 "immediate reimbursement of invoices" - 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").") solution. The combination of blockchain and cloud computing will effectively reduce the cost of enterprise blockchain deployment and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also be used in charity, insurance, energy, logistics, and the Internet of Things It plays an important role in many fields.
The three words "blockchain" were completely ignited during the Spring Festival that just passed, and the limelight overshadowed everything else. Some people said that this is With the arrival of a new era, the past has become classical, and some people say that everything is hype and ultimately a bubble.
In fact, blockchain technology is not a The new concept has been applied to many industries as early as the past two years, such as electronic signatures. Recently, the third-party electronic signature platform eSignBao 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, online contract signing, and web page evidence collection. , telephone recording, email storage, etc.
Taking online works rights protection as an example, since online rights protection generally adopts the method of collecting evidence after the fact, there is no evidence when the evidence is generated. Real-time confirmation of rights is carried out during the process, so the entire rights confirmation process takes a long time, is difficult and costly to obtain evidence, and is extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large number of online works.
< br />
eShanbao’s new intellectual property protection solution based on timestamp + blockchain starts from the user’s real-name authentication, solidifies the electronic data generated in the process in real time, and synchronizes it with the national The time source service of the Time Service Center stamps online works 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 to ensure that all areas 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 distributed trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certificate issuance, as well as the identity credibility of the parties, and reduced the cost of trust. However, It cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, users can be provided with real-time and reliable confirmation solutions.
Next, eSignBao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage and certification are only based on blockchain technology. The relatively superficial application is the first step to realize the implementation of blockchain technology, and the realization of real smart contracts isIt's 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. By 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 process the data generated in each transaction link.The system solidifies the certificate and accurately records the time, content, and data source of data generation through time stamp technology, summary algorithm, and electronic signature technology. 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 companies
Promote the rationalization of electronic guarantee rates
At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. 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 simply cannot produce these “certificates” and find it difficult to obtain financing., Expensive financing has become a problem 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. 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 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. So on the InternetIn a place where data is exploding and information is exploding, having such a place will be like a magical treasure land.
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, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. 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.
⑷ What are the application fields of blockchain
ASSET empowers global entity enterprises
Wall Street Fund Investment Bank provides extensive services to global entity industries. It has been committed to the incubation of small and medium-sized enterprises and has very scientific solutions to promote the rapid development of enterprises. ASSET is issued by Wall Street Fund Investment Bank , a digital token circulating in the global physical industry, ASSET is an open ecosystem based on blockchain technology. It is understood that ASSET has recently empowered blockchain for global alcohol companies. The core concept is to integrate blockchain technology with the real economy. Through product traceability and evidence collection, it integrates the most comprehensive alcohol industry intelligence that can directly affect corporate profits and losses. and market data, to allocate and convert value to alcohol production companies, suppliers, consumers, and potential consumers, subversively creating unprecedented driving force and unimaginable value returns for the industry.
⑸ How blockchain technology empowers real industries
Now there are domestic companies that have implemented blockchain technology into actual industries. For example, Wanglian Technology has put blockchain technology into practice. The blockchain is applied to financial services, medical health, IP copyright, Internet of Things, sharing economy, communications, education,
social management, charity, culture and entertainment and other fields
⑹ What is the development trend of blockchain , the future development trend of blockchain
The blockchain industry has broad development prospects driven by both policy and market.
Double-driven by policy and market, China’s blockchain-related industries are expected to move from reality to reality< br />In the context of the rapid development of blockchain, China complies with the needs of globalization, keeps up with international pace, and actively promotes research, standardization and industrialization development in related fields of domestic blockchain. Compared with the background of increasingly strict supervision of digital currencies such as Bitcoin, support and encouragement for blockchain technology has reached a global consensus, and domestic blockchain technology will also receive national and local policies in the next few years. support. Driven by the dual layers of policy and market, blockchain-related industries are expected to move from reality to reality, and blockchain technology will accelerate the exploration of possible application scenarios.
Forecast of global blockchain market size
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, the global blockchain market size is expected to increase from 2017 to 2017. It will increase from US$411.5 million in 2022 to US$7.6837 billion in 2022, equivalent to a compound annual growth rate of 79.6%. Given the wide range of applications for distributed ledgers and the rising market value of cryptocurrencies, there is a strong need to improve transparency, security, efficiency and streamline processes, as well as blockchain as a service (
BaaS). As a hot topic of development, the blockchain market will expand rapidly.

Next, follow CreditEase Puhui to learn about blockchain-related knowledge!
What is blockchain
Blockchain is a chain data structure that combines data blocks in a specific order in chronological order. Records of all transactions since the birth of the system are stored. The data on the blockchain is jointly maintained and stored by nodes across the entire network, while cryptography ensures that the block data cannot be tampered with or forged. So the blockchain is essentially a distributed shared database.
Blockchain is an innovative application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm in the Internet era. It is a way to solve trust problems and reduce trust.Information technology solutions at any cost. The application of blockchain technology can eliminate traditional trust intermediaries, subvert the old centralized model that has existed for thousands of years, solve the trust problem between strangers without the need for centralized trust intermediaries, and significantly reduce the cost of trust. Trust costs.
How blockchain can solve the pain points of supply chain finance
Supply chain finance is based on core customers, based on real trade background, and uses self-reimbursement trade financing. , which provides comprehensive financial products and services to upstream and downstream enterprises in the supply chain through professional means such as accounts receivable pledge registration and third-party supervision to close capital flows or control property rights.
The foundation of supply chain finance is the supply chain. The supply chain involves information flow, capital flow, logistics and business flow, and is naturally a multi-subject and multi-collaboration business model. In this case, if you want to carry out trade financing, you will first encounter many authenticity issues, such as the authenticity of the transaction and the authenticity of the documents, which require confirmation by multiple parties and consume a lot of manpower and material resources; secondly, the multiple entities involved , there is a problem of difficulty in interconnection. For example, the supply chain management system, enterprise resource management system, and even financial system used by each entity are different, making docking difficult. Even if they are connected, it will be difficult to share information due to inconsistent data formats and data dictionaries.
Characteristics of blockchain
1. Decentralization
The distributed structure of blockchain means that data is not recorded and stored in the center. Instead of using a dedicated computer or host, each node participating in the data transaction records and stores all data information. To this end, the blockchain system uses an open source, decentralized protocol to ensure complete recording and storage of data. The blockchain has built a complete set of protocol mechanisms, allowing each node in the entire network to participate in recording data while also participating in verifying the correctness of the recording results of other nodes. Only when most nodes (or even all nodes) in the entire network confirm the correctness of the record will the data be written into the block. In the distributed structure network system of the blockchain, the network nodes participating in the recording will update and store all data in the entire network system in real time. Therefore, even if some nodes are attacked or destroyed, the data update and storage of this system will not be affected.
2. Unforgeable
The principle of blockchain recording requires all nodes participating in the recording to jointly verify the correctness of the transaction record. Since all nodes are recording every transaction in the entire network, once the information recorded by a node does not match that of other nodes, other nodes will not recognize the record, and the record will not be written into the block.
3. Non-tampering
It is almost impossible to change a certain block and the transaction information within the block.If this block is changed, every subsequent block will be changed. Therefore, anyone trying to tamper with the data must simultaneously invade at least 51% of the nodes participating in the global record and tamper with the data.
Mathematical encryption
Each transaction requires a valid signature before it will be stored in the block. Only valid digital keys can generate valid signatures. Keys come in pairs and consist of a private key and a public key. Among them, the public key is public, and the private key is only visible and used by the owner, and is used for transaction signatures to prove digital identity.
What are the advantages of introducing blockchain?
First, to solve the problem of information islands, multiple stakeholders can set rules in advance to accelerate data interoperability and information sharing;
Second, according to property rights law , Electronic Contract Law, Electronic Signature Law, etc., the accounts receivable certificates of core enterprises can be converted into transferable and bankable confirmation certificates through the blockchain, so that the credit of core enterprises can be transmitted along trusted trade links. Based on mutual confirmation, the entire certificate can derive various operations such as splitting and traceability;
Third, provide credible trade data, such as providing an online basis under the blockchain architecture Tightly structured and complete records of contracts, documents, payments, etc. improve information transparency and achieve penetrable supervision;
Fourth, achieve cost reduction and efficiency improvement. After the credit of the core enterprise is transferred, small and medium-sized enterprises can use the credit line of the core enterprise to reduce financing costs and improve financing efficiency;
Fifth, realize smart liquidation of contracts. Automatic clearing and settlement based on smart contracts reduces manual intervention, reduces operational risks, and ensures the safety of repayment.
CreditEase Puhui believes that blockchain supports commercial applications with high performance, high scalability, and high security, provides financial technology companies with multi-level data security and privacy protection, and supports automatic monitoring and failure Alerts help track all transactions that occur in the system and contribute to the healthy and orderly development of the financial technology industry.
⑻ What is the development trend of blockchain, and what is the development trend of blockchain technology?
The development trends of blockchain are:
01. The long-term direction of the blockchain industry Well, the core value is generally recognized;
02. Technology development is more pragmatic, with engineering and ecological construction becoming the focus;
03. Blockchain and privacy computing develop collaboratively;
04. Blockchain Chain interconnection has become the focus, and the future of value interconnection is promising;
05. The call for blockchain infrastructure is gradually rising, and the construction model still needs to be explored in depth;
06. Blockchain cannot conquer the world, and needs to cooperate with many Technology cooperation completes digital transformation;
07. The application of certificate storage takes the lead and gradually moves toMulti-party collaboration and value transfer are moving forward;
08. The importance of the blockchain alliance business model has become more prominent;
09. Government support will still be an important driving force for industrial development in the future;
10. As the number of blockchain practitioners increases, the relative shortage of talents will continue to exist.
(8) Blockchain connects the world with each other. Extended reading:
Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. thing. Compared with traditional networks, blockchain has two core characteristics: first, data is difficult to tamper with, and second, it is decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.
Blockchain is still mainly used for certificate storage. For example, the application of blockchain in supply chain finance, product traceability, trade finance and other fields has achieved certain results, but its application model is still based on documents, contracts, The main thing is the deposit certificate of the bill. As the industry application of blockchain continues to deepen, in order to further promote the role of blockchain in promoting the development of the real economy, in the future, we will focus on the development of multi-party collaboration and value transfer applications.
Blockchain is not only a technology, but also a concept and a cooperation model. Blockchain will connect all parties in the industry upstream and downstream, and it is necessary to rely on the common interests of the alliance to bring together all participants. At present, there are two main organizational models of blockchain alliances, namely core organization leadership and participating organizations co-governance. Both blockchain alliance business models also have their own advantages and disadvantages. In order to achieve long-term and stable development of the alliance, how to build and which kind to build? The model also requires continued in-depth exploration by the industry.

⑽ How does blockchain achieve distributed consensus?
The entire human society can only constantly find a balance between distribution and consensus. The two have shown an alternating situation in the past. The distribution is constantly iterating, and each new cycle will inherit the results left by the previous cycle. As a result, human beings can continue to reach a larger scope and higher level of civilization.
The distribution period is mainly characterized by the development of individual interests, but this does not mean that there is no centralized decision-making; the consensus period adopts centralized management that prioritizes efficiency, and distribution will be appropriately considered for overall stability and other demands.
The emergence of distribution often occurs at the end of consensus. At this time, due to uneven distribution and lack of incentives, the public has been unable to obtain further benefits, and the development of the entire society has also slowed down significantly. At this time, we prefer to use distribution Overturn the original small-scale consensus.
Significance
The reason why the Internet can play a huge role in social development lies in the establishment of a decentralized and distributed network and the The use of the TCPIP protocol, which promotes equality and realizes resource sharing, eliminates the problem of over-concentration of information and decision-making caused by centralization in the industrial age.
The emergence of blockchain is based on the prosperity created by the Internet. Through the technological innovation brought by the new distributed ledger, there is an opportunity to further promote the transfer of value. This can solve the obstacles encountered by today's Internet in the process of interconnection and interoperability entering deeper areas, and once again enhance the level of human prosperity.
