① What is the concept of blockchain

Literally understood, blockchain includes two concepts: block and chain. The blockchain itself is composed of blocks, and the network built by linking different nodes together is the blockchain. The main function of the blockchain is to store information. Any information that needs to be saved can be written to the blockchain or read from it.

Each block stores: some valid record or transaction; information involving the block; links to the previous block and the next block through the hash of each block - which can be considered a block The unique code of the fingerprint.

Each block therefore has a specific and immovable position within the chain, as each block contains information from the hash of the previous block. The entire chain is stored in every network node that makes up the blockchain, so an exact copy of the chain is stored among all network participants.

Uses

Essentially, blockchain can be used to store any type of information that must remain intact and be more secure than going through a middleman. , decentralized and cheaper ways remain available. Additionally, since the stored information is encrypted, its confidentiality is guaranteed as only those with the encryption key can access it.

Using blockchain in healthcare. For example, health records can be consolidated and stored on the blockchain. This means that every patient's medical history is secure and, at the same time, available to every authorized doctor, regardless of the health center where the patient received treatment. Even the pharmaceutical industry could use this technology to authenticate medicines and prevent counterfeiting.

Blockchain is also very useful for managing digital assets and documents. The problem with digitization so far has been that everything is easily copied, but Blockchain allows you to record purchases, deeds, documents or any other type of online asset without it being counterfeited.

② How Life Chain uses blockchain technology to ensure data security

Through chain entities like neural unit networks, blockchain can achieve practical health application scenarios ( Life chain system), including offline physical health stations, rehabilitation hospitals and other medical and nursing institutions and online medical and nursing data + Internet of Things system

③ SHS uses blockchain to further explore the development of medical insurance

Insurance has high risks, strong dispersion and high sensitivity, which are naturally consistent with the attributes of blockchain. The traceability feature of blockchain technology can make the medical insurance service process more transparent; the security capabilities of blockchain can well solve the privacy protection and commercial information security issues in data transmission; and the consensus mechanism of blockchain can The credibility of the transaction is further guaranteed from the source. Due to the above-mentioned characteristics of blockchain, it can largely help the medical insurance industry to realize information sharing and connection of a large number of dispersed nodes within the industry, between industries and between users, thereby greatly accelerating the space and speed of medical insurance innovation.

With the help of blockchain technology, everyone participatingAuthors can now individually and digitally load information relevant only to their shared contracts. This way, when a transaction is being executed, everyone involved can view the status, history, and process of being authorized. Peer-to-peer (P2P) transmission and open and transparent blockchain technology are becoming very potential value propositions in the industry.

Because blockchain permanently records all transactions between its participants, it is able to provide a level of transparency that current paradigms in the insurance sector do not offer.

SHS (Smart Health Sandbox) selects the SHA-256 encryption mechanism to encrypt the data in the chain. The transaction data and trader information between users are only available to the transaction parties and users with corresponding permissions. Can be viewed. Medical insurance based on blockchain smart contracts will provide a more optimized insurance model. Users do not need to pay expensive insurance management costs, but directly establish intelligent insurance contracts on the blockchain, with management costs close to zero, allowing users to Insurance funds are completely managed and controlled by the user. Medical institutions on the chain can also seamlessly connect with mutual medical insurance, data connectivity, and economic connectivity, allowing people to obtain better medical insurance services.

The third level of blockchain technology development is the process of common development and mutual promotion. Especially for the insurance industry, the application of blockchain technology will greatly improve business efficiency and reduce business risks.

④ What are the application fields of blockchain?

What are the application fields of blockchain? Introduction to the Blockchain Application Industry
As we all know, blockchain is very popular now. It is a shared distributed database technology. Blockchain technology will have very good results in different industries with its remarkable characteristics. Development prospects, so what are the application areas of blockchain?
Blockchain Applications
1. Digital Currency: At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Since the emergence of Bitcoin, hundreds of digital currencies have appeared one after another, and a relatively large industrial chain ecosystem has been formed around the generation, storage, and transactions of digital currencies. Taking Bitcoin as an example, participating institutions can be mainly divided into four categories: infrastructure, trading platforms, ICO financing services, and comprehensive blockchain services.
2. Financial application: Blockchain has inherent advantages in the financial field. On the Internet, this is determined by the genes of blockchain. From a subjective point of view, financial institutions are the most willing to explore blockchain applications and need new technologies to improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If blockchain is applied in the financial field,If verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to digital currency applications, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.
(1) Insurance business: With the development of blockchain technology, personal health status, accident records and other information may be uploaded to the blockchain in the future, allowing insurance companies to be more timely and timely when customers apply for insurance. Accurately obtain risk information to reduce underwriting costs and improve efficiency. The shared and transparent characteristics of the blockchain reduce information asymmetry and the risk of adverse selection; while its historical traceability characteristics are conducive to reducing moral hazard, thereby reducing the difficulty and cost of insurance management.
(2) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue.
(3) Digital tickets: The pain points in this field lie in three risk issues. Operational risk: Due to the centralization of the system, once there is a problem with the central server, the entire market will be paralyzed; market risk, according to statistics, in 2016, there were seven risk events involving hundreds of millions of dollars, involving multiple banks; moral hazard , there are incidents such as "one ticket selling more" and false commercial bills in the market. Blockchain's disintermediation, system stability, consensus mechanism, and non-tampering characteristics reduce operational risks, market risks, and moral risks in traditional centralized systems.
(4) Cross-border payment: The pain points in this field are long payment cycle, high fees and low transaction transparency. The third-party payment company is the center to complete the accounting, settlement and liquidation in the payment process, and the payment cycle is long. For example, the payment cycle for cross-border payments is more than three days, and the cost is high. The blockchain is deintermediated, transactions are open, transparent and cannot be tampered with. No third-party payment institutions are involved, which shortens the payment cycle, reduces fees and increases transaction transparency.
(5) Credit information management: The pain points in this field are the lack of data sharing, information asymmetry between credit information agencies and users; formal market-oriented data collection channels are limited, and the battle for data sources consumes a lot of costs; data privacy protection issues are prominent , the traditional technical architecture is difficult to meet new requirements, etc. In the field of credit reporting, blockchain has the characteristics of decentralization, trustlessness, timestamps, asymmetric encryption and smart contracts. At the technical level, it ensures that limited and controllable credit can be achieved on the basis of effectively protecting data privacy. Data sharing and verification.
(6) Supply chain finance: The pain points in this field are the long financing cycle and high costs. Supply chain coreWith the enterprise system as the center, it is difficult for third-party credit enhancement agencies to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs. The blockchain's deintermediation, consensus mechanism, and non-tampering characteristics eliminate the need for third-party credit enhancement agencies to verify the authenticity of various relevant certificates in the supply chain, reducing financing costs and shortening the financing cycle.
(7) Asset securitization: The business pain point in this field lies in the fact that the authenticity of the underlying assets cannot be guaranteed; there are many participating entities, multiple operating links, low transaction transparency, and information asymmetry, making it difficult to control risks. The pain point of data lies in the low efficiency of transfers between participants, the clearing and reconciliation of funds between parties’ trading systems often requires a lot of manpower and material resources, and there are multiple online and offline channels for asset repayment, making it impossible to monitor the true status of assets, and there are still assets After the package is formed, the trust of all parties in the transaction chain in the authenticity and accuracy of the underlying asset data is an issue. Blockchain's deintermediation, consensus mechanism, and non-tampering characteristics increase data flow efficiency, reduce costs, monitor the true status of assets in real time, and ensure the trust of all parties in the transaction chain in the underlying assets.
3. Blockchain + Industry Application:
As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain+" is becoming a reality.
(1) Blockchain + Medical: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health records (EHR), DNA wallets, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.
(2) Blockchain + Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things application of blockchain technology will become a very important application field.
(3) Blockchain + IP copyright & cultural entertainment: The Internet is developing better and better, and digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain has the characteristics of disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized Transfer, and ensure that the transfer process is credible, auditable and transparent, effectively preventing piracy and other behaviors.
(4) Blockchain + Public Services & Education: In the fields of public services, education, charity and public welfare, file management, identity (Issues such as qualification) certification and public trust all exist objectively. The traditional method is to rely on a credible third party for credit endorsement, but problems such as fraud and deficiencies still exist. Blockchain technology can ensure the integrity, permanence and unchangeability of all data, and thus can effectively solve the difficulties and pain points in these industries in terms of certificate storage, tracking, association, and backtracking.

⑤ 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 to identify them carefully.

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

Digital currency

After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the 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. digital ticketIn terms of data and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Digital Government Affairs

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

Evidence-based anti-counterfeiting

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

Data services

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

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

In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, 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, eSignBao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage and certification are only superficial applications based on blockchain technology. The first step is to realize the implementation of blockchain technology, and the second step is to realize real smart contracts. "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. Traditional digitalizationDue to the centralized nature of the certification system, the data is easily tampered with, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.

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

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding 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.

Solving the financing problems of successful bidders

Traditional corporate loans mainly evaluate the company's solvency: there are requirements for collateral, audited statements, sustained profits, etc., but most small and medium-sized enterprises Enterprises simply cannot produce these "proofs", and difficult and 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 trustworthiness but also reduces the risk of corruption. The entire system relies on a centralized authority.

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

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

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

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

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

Decentralization solves problems.

What application scenarios can blockchain have?

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

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

What are the economic applications of blockchain?

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

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

The second type is applied to enterprise operation and management

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

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

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

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

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

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

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

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

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

In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creatingA new ecological model based on technological trust

What is blockchain

If you explain blockchain in non-technical terms, blockchain is a place to store data, but the data stored in the blockchain It is safe and reliable and does not require anyone to care about it. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.

What can the blockchain do?

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

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

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

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

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

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

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

1. Cloud storage

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

Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.

2. Medical aspects

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

⑥ What is the application of blockchain technology in the medical industry?

Jinwowo believes that the birth of blockchain technology has made the entire population Databases and health information exchanges become obsolete. Blockchain technology can improve data security and save explicit and implicit costs.
The application of blockchain technology in the medical field is divided into these aspects: electronic health records, DNA wallets, drug anti-counterfeiting and protein folding. In the future, Jinwowo Network Technology will continue to explore the value of blockchain technology in the commercial field.
