Ⅰ Low-carbon consensus, linking the world - global anti-warming, ECO2 in action!
On Saturday, September 5, 2020, the "Global Anti-Warming Blockchain Application Seminar" and the "ECO2 China Community First Anniversary Celebration" were grandly held in Taiyuan, China. This event is hosted by ECO2 Foundation Ltd. (ECO2 Foundation), China Energy Conservation Association Carbon Trading Industry Alliance, National Information Center China Economic Network, International Emissions Trading Association (IETA), Global Energy Internet Development Cooperation Organization, International Trusted Block Supported by international exchange organizations such as the Chain Application Association (INATBA), and strategically supported by 30+ media. This ancient city with a history of more than 2,500 years was once the ancient capital of nine dynasties. Many emperors in history have left their roots in this city. It is the "land of dragon prosperity" in Chinese civilization, so Taiyuan is also called: Dragon City. . Another significance of choosing to hold this conference here is that Shanxi is a major coal-producing province in China and has a profound impact on the development of the coal industry and the "low-carbon economy" advocated by the country.

Guests attending this seminar include: Professor Zhang Juntao, executive deputy secretary-general of the Carbon Trading Industry Alliance of China Energy Conservation Association, Professor Zhu Youping, deputy director of the China Economic Network Management Center of the National Information Center, and founder of ECO2 Mr. Hao Xuanzheng and co-founder Mr. Lin Yuyang. And low-carbon volunteers from all over China have gathered here to discuss how to use blockchain technology to apply to "global anti-warming" measures, and to advocate low-carbon environmental protection, which must be taken into action!
II Which fields are blockchain suitable for?
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 equity proof blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owners of equity can be confirmed.
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.
Ⅲ In the future of carbon neutrality, how can blockchain "go up"
#01
< p> We are serious about achieving carbon neutralityIn recent years, the issue of global warming has received increasing attention, and the issue of climate change has gradually been recognized by everyone.
In order to deal with the global climate crisis, our country is also vigorously promoting the concept of "carbon neutrality". On the one hand, it is a solemn commitment to address global climate issues; on the other hand, energy substitution is also an important engine for economic growth in the post-epidemic era.
Xiaoou’s note: What are carbon peak and carbon neutrality?
"Carbon peak" refers to a certain moment when carbon dioxide emissions reach a historical high and then gradually fall back;
" "Carbon neutrality" refers to offsetting the carbon dioxide or greenhouse gas emissions produced by itself through afforestation, energy conservation and emission reduction, achieving positive and negative offsets, and achieving relatively "zero emissions."
It is understood that China will achieve carbon peak and carbon neutrality goals by 2030 and 2060 respectively.
The global carbon neutrality goals are as follows:
Currently, we choose to adopt a "carbon pricing mechanism" to achieve the goal of carbon neutrality. The so-called carbon pricing, that is, "who pollutes, pays". If you want to emit carbon dioxide and other greenhouse gases, you must first obtain the right to carbon emissions, and then pay for the right.Pay the fee. There are two specific methods: levying a carbon tax and establishing a carbon emissions trading system (referred to as carbon trading).
Carbon tax policy is not difficult to understand. At present, the public discussion is more about carbon trading.
The so-called carbon trading refers to treating carbon dioxide emission rights as a commodity, which can be bought and sold between enterprises through a certain mechanism. This market formation is usually artificially created by the government through emission control of energy-consuming enterprises.
However, from a global perspective, a unified global carbon trading market has not yet been formed, and my country is still in the pilot stage of carbon emissions trading.
Currently, a total of 8 regions are currently carrying out carbon emission trading pilot projects, namely: Beijing, Tianjin, Shanghai, Chongqing, Hubei, Guangdong, Shenzhen and Fujian.
According to ICAP statistics, the total amount of quotas in the world's 21 operating carbon markets in 2020 is approximately 4.782 billion tons. Among them, the eight pilot markets totaled 1.425 billion tons, accounting for 29.8%, second only to the EU.
According to Guosen Securities’ prediction, as the market improves and coverage increases, transactions will become more and more active, and the national carbon trading market transactions may reach more than 100 billion in 2030.

What kind of chemical reaction will blockchain + carbon neutrality produce?
Today, the carbon neutrality movement is in full swing. In addition to energy-saving and emission-reduction measures in real life, some emerging new technologies are also providing more solutions to achieve this goal. Taking blockchain as an example, it trades efficiency for energy saving, thereby reducing carbon emissions, and may speed up the achievement of carbon neutrality.
A special researcher at Ouke Cloud Chain Research Institute said:
“In terms of helping achieve carbon neutrality goals and industrial transformation and upgrading, the advantages of blockchain-related technologies and models are mainly reflected in the following: Three aspects: First, on the enterprise side, the natural advantages of blockchain data transparency and traceability and supply chain management can effectively improve the overall output efficiency and resource utilization of each link in the industrial chain, and activate low-carbon and zero-carbon related suppliers. and the market value and competitiveness of related processes; secondly, on the management side, carbon accounting standards based on blockchain technology and smart contract execution can be established to achieve unified management of the entire industry, automatic sorting, and carbon emission early warning with clear rights and responsibilities. Rewards and penalties, etc.; thirdly, on the energy side, blockchain technology is deeply involved in energy distribution, trading, recycling and other aspects, such as focusing on energy distribution in low-carbon industries, promoting the transformation of the energy market from centralized to decentralized, reducing waste, etc. Objectively, it also stimulates the vitality of the renewable energy market."
In addition, he also pointed out that in the process of assisting "carbon neutrality", blockchain technology does not exist independently. It can only be integrated with big data. , privacy computing, knowledge graph, Internet of Things and other technologies, only by opening up data islands and analyzing and summarizing data on the chain can the role of blockchain be better utilized, thereby creating a more visible and credible carbon regulatory environment.
Today, the carbon trading market is gradually getting on the right track, and the application of blockchain in this field is also maturing. At present, IBM, State Grid, Huawei, etc. have also joined the practice. As a new generation of disruptive core technology that has emerged after steam engines, electricity, and the Internet, the blessing of blockchain is bound to make my country's carbon trading market more standardized and dynamic.
IV How does the application of blockchain technology in the agricultural field help?
What problems does blockchain solve in agriculture?
1. Traceability of agricultural products
The traceability of agricultural products has always been a pain point in agriculture. Blockchain technology can make records non-tamperable, so there is detailed data from the production end of agricultural products to the circulation end and consumers, which can realize consumers' clear consumption and increase consumers' willingness to buy.
The traceability of agricultural products can improve the safety of agricultural products and food.
2. Information transparency
In addition to traceability in the agricultural field, there is also the problem of opacity in the information between producers and demanders.
Once blockchain technology is applied to agriculture. We can use big data analysis to establish credit rating references for growers and purchasers; use smart contracts to ensure fair transactions between growers and purchasers. At the same time, blockchain technology can improve the contractual spirit between buyers and sellers of agricultural products.
Also, with the advent of blockchain in the food supply chain, this could streamline the process as the data management system integrates a range of brokers, farmers, processors, distributors, regulators, retailers and Data management systems are becoming more transparent for consumers to put on their radar.
3. Reduce costs
After the application of blockchain technology, the costs of production and circulation will be greatly reduced. For example, blockchain technology solves the functions of automatic information storage and database, thus reducing manual investment and investment in other facilities.
In addition, blockchain and applications realize the interconnection of everything, helping manufacturers and distributors reduce various expenses. At the same time, reductions in production and distribution costs will also reduce the prices of agricultural products, ultimately benefiting consumers.
Of course, in addition to the above three reasons, blockchain technology can also be applied in agricultural subsidies, land registration, etc. to solve problems such as corruption and rights and interests.
Therefore, the application of blockchain technology in the agricultural field has to be recognized by people at all levels.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
Application areas of blockchainThere are digital currencies, certificates, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. .
IV 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, 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 toIdentified carefully.
Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.
Digital currency
After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the 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. The current supply chain finance is difficult to benefit the industrial chainBecause they often have no direct trade relations with core enterprises, it is difficult for financial institutions to assess their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.
Digital Government Affairs
Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. 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 significantly 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. For the current stage of blockchain developmentIn order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.
The three words "blockchain" were completely ignited during the Spring Festival that just passed. The limelight overshadowed everything. Some people said that this was the arrival of a new era. The past It has become a classic, and some people say that it is all hype and is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, 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-Shuabao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that dataEvidence storage and issuance are only superficial applications based on blockchain technology. They are the first step to realize the implementation of blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.
From a technical perspective, blockchain is not a brand-new technology, but a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. 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 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. The traditional digital witness system is prone to data tampering due to its centralized characteristics, and the data is easily damaged or lost during the storage and migration process. From the perspective of security and usability,All have certain flaws.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates
Promote financial services and corporate financing for bidding 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 problem of successful bidders
Traditional corporate loans mainly evaluate the companySolvency: There are requirements for collateral, audited statements, sustained profitability, etc., but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. 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 organizations work every dayAll are using blockchain management forms
However, this blockchain application for organizational relationships cannot generate 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 it in layman termsTo explain the blockchain, the blockchain is a place to store data. 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 explode, there can be such a place. It 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 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.
