⑴ What are the application examples of blockchain?

1. Judicial deposition

On September 18, 2018, the Hangzhou Internet Court officially chain, becoming the world’s first court to use blockchain for trials.

It is understood that the complainant can submit electronic evidence such as the contract, rights protection process, service process details, etc. online through the online complaint portal to nodes on the chain such as notary offices, judicial appraisal centers, CA/RA institutions, and courts. Come and witness and endorse together to provide one-stop service for the prosecutor. The Internet Court of Hangzhou, Zhejiang Province made a public judgment on a dispute over infringement of the right to disseminate work information online, and for the first time confirmed the legal validity of electronic data stored using blockchain technology.

2. Logistics field

In early 2018, Cainiao and Tmall International jointly announced that they have used blockchain technology to track, upload, and verify the logistics of cross-border imported goods. Link information.

After all nodes of the logistics chain are connected to the blockchain, the goods will be traceable from the manufacturer to the consumer, forming a complete chain; the more links the goods are missing, the more fake they will be exposed. Product probability is greater.

3. Electronic invoices

On August 10, 2018, Shenzhen Guomao Revolving Restaurant issued the country’s first blockchain electronic invoice. It is understood that this issued block The chain electronic invoice is led by the Shenzhen Municipal Taxation Bureau and Tencent provides underlying technology and capabilities.

Different from traditional electronic invoices and simple electronic invoices uploaded to the chain, this blockchain electronic invoice combines "fund flow and invoice flow" into one, integrating invoice issuance and The combination of online payment simplifies the entire process of invoice application, invoicing, reimbursement, and tax filing.

⑷ What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the price difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

⑸ [One of the top ten blockchain government cases] Ant Blockchain-Hangzhou Internet Court Judicial Chain Case

According to Hangzhou Daily, in September 2018 On March 18, the Hangzhou Internet Court announced that the judicial blockchain was officially launched online, becoming the first court in the country to apply blockchain technology to resolve disputes. The judicial blockchain makes the entire process of electronic data generation, storage, dissemination, and use trustworthy.
Plaintiffs can submit electronic evidence such as contracts, rights protection processes, and service process details online through the online complaint portal, which will be submitted by notary offices, judicial appraisal centers, CA/RA institutions, courts, Ant Financial and other on-chain nodes. Joint witness and joint endorsement provide one-stop service for the prosecutor. The judicial chain has greatly reduced the cost of offline evidence storage and collection, and improved the efficiency of the judgment process, thus enabling many cases that were previously unworthy of prosecution due to the high cost of rights protection to be able to achieve better rights protection through the blockchain; Judicial The chain solves the problem of low judicial service efficiency, realizes the integration and sharing of judicial data, and breaks down data silos; the judicial chain promotes the construction of a social credit system, reduces judicial costs, uses technology as an engine, promotes innovative development, and leads the transformation, upgrading and reduction of judicial services.

Citing the analysis of the "Blockchain Judicial Evidence Application White Paper" from the Trusted Blockchain Promotion Plan, with the rapid advancement of informatization, a large amount of evidence in litigation is presented in the form of electronic data. The specific manifestations of electronic evidence in judicial practice are becoming increasingly diverse, and the frequency of use and data volume of electronic data storage have increased significantly. Different types of electronic evidence are formed in different ways, but they generally have the characteristics of being easy to perish, easily tampered with, and highly dependent on technology. Compared with traditional physical evidence, it is more difficult to determine the authenticity, legality, and relevance of electronic evidence in judicial review. .

In judicial practice, parties generally lack the ability to produce evidence, and the electronic evidence provided to the court is of poor quality. There are a large number of problems such as improper evidence collection procedures, incomplete evidence, and poor pointing to the facts of the case, which directly affects the electronic evidence. The proportion of evidence admitted in litigation.

The traditional storage method of electronic evidence is essentially a centralized storage method, which may easily cause the storage data to be lost or be compromised. .

At the same time, electronic data relies on electronic media for storage. For storage security, multiple backups and other methods are often needed. In addition, electronic media have a long service life, which makes storage costs higher.

(2) Problems in evidence collection

Currently, when some locally generated electronic data is collected for evidence, the originals are intelligently retained in the device that generated the electronic data, and the original evidence and Devices are indivisible. Once the original evidence leaves the device, it becomes a copy and cannot become the basis for a final verdict. This leads to lawsuitsThere are many restrictions in the software.

In addition, the Internet software service provider cannot give a definite answer as to whether the so-called original is the real, original and complete data at the time when the time occurred. It is also doubtful whether the evidence obtained is the original.

(3) Problems in demonstration

Electronic data display and fixation are important aspects of data use. Since electronic data exists in the form of electronic information stored in electronic hardware, To obtain its content, you need to use responsive software to read and display it, which makes it difficult to demonstrate. It may also increase the burden of proof on the parties due to the need for notarization, and waste social judicial resources.

(4) Issues in Evidence

In litigation, both parties will submit their own electronic data as evidence. When the parties individually control their own data, it is easy for the evidence submitted by both parties to be inconsistent or even contradictory. In the absence of other supporting evidence, it is very difficult to determine the authenticity of the evidence, and the electronic data submitted by both parties cannot be used as the basis for deciding the case. In this situation where the facts of the case cannot be determined, the judge is likely to have to rely on assigning the burden of proof to decide the case. The general principle of allocating the burden of proof is that whoever makes the claim must provide evidence. If he cannot provide evidence, he will bear the consequences of losing the case. In this case, a party that actively tamperes with its own data can benefit from this burden of proof arrangement.

(5) Problems in evidence identification

All evidence "must be verified to be true before it can be used as the basis for finalizing a case", which is the most important and universal evidence in the world. One of the principles of justice. The identification of evidence is usually a process of identifying the "three properties" of evidence, namely the authenticity, legality and relevance of the evidence. Electronic data used as evidence also needs to pass the "three characteristics" judgment. Due to the large amount of data, strong real-time nature of electronic data, high storage costs, and difficulty in identifying the originals, it is still difficult to identify the "three properties" of evidence. Electronic data often cannot support the case because it is difficult to identify, which is detrimental to the case. Both the judge and the parties caused greater pressure.

Quoting from the sharing by Li Zhiguo, head of Ant Financial’s judicial evidence deposit products, on the theme of “Ant Blockchain’s Exploration in the Field of Judicial Evidence”, he believes that in the past 20 years, the Internet industry has The key word is connection. In the PC Internet era, terminals were connected through PC interconnection. At that time, companies that discovered this trend seized huge business opportunities such as portals and search engines. In 2013, we entered the era of mobile Internet. In this era, many smart terminals and personal devices are connected together through the mobile Internet. The number of terminal devices and online time have been greatly improved. Those who seized the opportunity at this stage created super applications such as Weibo, WeChat, and Alipay. A very important change that we are currently paying attention to is that as the changes in connections continue to expand, the quality of connections has also undergone very large changes. This is called the thirdThe two curves originally connected information, but now they are likely to become assets.

So what is the difference between assets and information? There are three main differences.

First, assets are unique, while information can be copied infinitely. In the Internet era, the cost of information transmission can be minimized through copying. However, when the connected object is an asset, there is a fatal flaw, that is, it cannot be transmitted through copying. After the asset is given to a person, It cannot be given to anyone else.

The second point is that assets are more fragile and precious than information. Assets are money. In the process of information digitization, it is easy to put information on the Internet, but for assets, this does not work, because behind the assets are real interests.

The third point: Compared with assets and information, assets have very high security requirements, and many problems must be faced, including attacks by hackers, competitors, fraud, etc. These are all linked assets. issues that need resolving. This is the third difference between assets and information. If there is a dispute over assets, they need to be resolved. In reality, it can be resolved by the court, but if it is on the Internet, it is difficult to deal with it.

The three characteristics of assets mentioned above are difficult to solve through traditional Internet methods. At the same time, the development of the Internet has made people lazier and lazier. If 10 years ago, many people could accept that asset connection would take a long time, but now it is difficult for people to accept it. For example, in order to sign a contract, it takes two to three days. It takes weeks to mail, and it costs a lot to go in and out of many traditional institutions frequently in order to make a cross-border payment. And compared with the connection method 20 years ago, the current Internet connection has become much more difficult, because many people find that after information is connected, the data becomes very valuable. What to do if it is valuable? The only way is to sink the value. When it sinks, it becomes a deep well of value. The larger the scale, the deeper the value. At the same time, another problem will be formed called data island. These issues need to be considered and resolved by the judicial chain.

Now, the court is standing at a historical opportunity node and has the opportunity to become a basic component of data generation and completion of connections. Disputes will inevitably occur over assets, and after a dispute occurs, the court will conduct a full-link review. This is a unique value, the value of the last mile of the Internet. By connecting assets, breaking data islands and value wells, this is the real value completion. This model actually belongs to small and medium-sized enterprises, including For individual users, the above is the value basis of the judicial chain.

If an island of value appears and needs to be connected, there must be various connection methods. There are four main ways to connect.

The first is not to connect.Connect it and put it in a bank safe;

The second way is a bad connection, that is, through technological leadership and inequality, depriving the ownership of data assets through hacking technology, when there is no When connecting legally, bad connections must exist;

The third type is a connection that seems to be a good connection, but is actually a fragile connection. Nowadays, there are many ways to connect. When the market situation is relatively good, When the bubble is relatively large, it has a certain market, but once it encounters real value, it bursts;

The fourth type is the judicial chain, which can be summarized in 15 words, that is, the whole process is recorded, the whole process is recorded, and the whole process is recorded. The link is trusted and witnessed by all nodes.

How can the judicial chain be technically credible and institutionally credible at a low cost?

First of all, the first problem is that assets are fragile, so when connecting assets, they must have the basic characteristics of real security. Security includes privacy protection, which is not a simple matter. The first day Alipay was born started with secured transactions, solving the problem of the authenticity of previous transactions between buyers and sellers. Later, based on Alipay, Sesame Credit was proposed, and many Everyone has Zhima Credit points, and through past credit records, big data and artificial intelligence are provided as a reference for whether the user can fulfill the contract, making real security a step further. Next comes the blockchain. The blockchain provides a very important capability, that is, the truth cannot be tampered with, which makes trust a big step forward in the level of real security. Therefore, the first problem solved by the judicial chain is to ensure that the bottom connector is real and safe when connecting assets. This real safety is not something you talk about in words, nor is it a technology in a laboratory, but a technology in a laboratory. It has been recognized by users, tested by the market and tested by large-scale business volume.

The second question is very critical. When everyone is connected through a real and secure connector, once the data assets are compromised, how to deal with disputes? The judicial blockchain has been moving in this direction in the past two years. By bringing notary offices, judicial appraisal centers, and courts to the bottom of the judicial chain, the data is authenticated accordingly, ensuring that once a dispute arises about data assets, it can be be dealt with fairly and effectively. This is a very powerful system, which is the fundamental reason why the judicial chain is the real solution to the last mile problem of the Internet. So far, the judicial chain has ensured technical credibility and institutional credibility.

The third problem is that in the interconnection of assets, the cost of connection cannot be too high. Users have developed the habit of obtaining countless information with just a click of the mouse and a search button. Blockchain has been popular for many years, but so far there are less than 20 million real users, and the daily activity is very low. The first reason is that it is too difficult to use, and the second reason is that the cost of use is too high. Therefore, when connecting assets, it must be very simple, very easy to use, and cost-effective.Very low. Just like when Alipay first implemented real-name authentication, it could quickly complete user payments through face scanning, and at the same time, the security level was very high. Therefore, real connectors must have the characteristics of low cost and high applicability.

The judicial chain has achieved technical credibility and institutional credibility, and the cost of connection is not high, opening a new era of blockchain for asset connection.

The Hangzhou Internet Court’s judicial blockchain makes the entire process of electronic data generation, storage, dissemination, and use trustworthy. Through the overall complete structure, it can solve the entire life cycle of electronic data generation, storage, dissemination, and use on the Internet, especially the whole-process trust issue at the generation end.

The blockchain consists of a three-layer structure:

1). The first is the blockchain program. Users can directly record the entire process of operation behavior in the blockchain through the program. , such as online submission of electronic evidence such as electronic contracts, rights protection processes, service process details;

2), The second is the full-link capability layer of the blockchain, which mainly provides real-name authentication, electronic signature, time Stamping, data storage and trusted services throughout the blockchain process;

3), the third is the judicial alliance layer, which uses blockchain technology to integrate notary offices, CA/RA institutions, forensic identification centers and The courts are connected together in the alliance chain, and each unit becomes a node on the chain.

The electronic evidence platform launched on the judicial chain of Hangzhou Internet Court directly establishes a special data channel between evidence and trial, making the collection, fixation, transmission and use of evidence more convenient and efficient.

In the past, when going to the Internet Court for litigation, evidence was submitted electronically and then uploaded to the "Hangzhou Internet Court Litigation Platform" (www.netcourt.gov.cn). For example, notarized documents are usually uploaded by scanning. The electronic evidence platform launched today first has a long "tentacle", and it can achieve seamless connection with other electronic data, such as notary offices. Then the notarized documents can be uploaded to the electronic evidence platform with one click and used directly as litigation evidence. For another example, when involving transaction disputes on e-commerce platforms such as Taobao and JD.com, mutual financial platforms, and wealth management platforms, third-party data service providers (such as operator platforms, electronic contracting platforms, and certificate depository institution platforms) can also directly transmit electronic data. The electronic evidence platform effectively solves the difficulties faced by parties in collecting electronic data evidence on their own and greatly saves the economic and energy costs of producing and cross-examining evidence in court trials.

The "electronic" evidence that was originally just scanned or typed has truly transformed into "electronic evidence". Through the third-party storage platform, "electronic data" is easily lost and tampered with. The magic spell forms a unique “data ID card” that cannot be tampered with, and is synchronized and backed up to the electronic evidence platform in real time. After entering the proceedings, it has been saved in the electronicThe "data ID card" of the sub-evidence platform will also automatically compare with the original electronic data to determine whether the electronic evidence has been tampered with in the later period, thereby ensuring the authenticity of the electronic evidence.

These electronic data have coded ID cards, which become the "elements" of each case. The platform classifies these elements and then matches them to each case. In this way, the system automatically matches The key element is to import electronic evidence into each case to form a system that automatically files cases without a judge. We can imagine that we will soon be able to achieve a case filing speed of tens or hundreds per minute.

Finally, when these evidences become electronic data and are stored on the platform, in addition to the Hangzhou Internet Court, which can carry out judicial use on the platform during the trial of the case, other relevant institutions (such as other people with permission) Courts, judicial appraisal agencies, notary agencies, filing agencies) can all retrieve relevant evidence from the platform in accordance with procedures, and the co-construction and sharing of resource data will also be achieved.

Taking the Shanghai Pudong Notary Office’s data storage platform that has opened up the Hangzhou Mutual Judicial Chain as an example, we will introduce the complete closed-loop process from the data protection platform to judicial litigation.

1. Register the business platform and perform real-name authentication

Enterprise A, a design company, opens the Shanghai Pudong Notary Office data storage platform page and completes real-name identity authentication after registration.

2. Original data storage

When design company A completes the design of a work and archives the original work data, it initiates a remote storage call through its own business system Interface, call the RESTful API of the notary office's data storage platform to complete the storage of the design work file HASH and related elements. The deposit certificate will also be sent to the Judicial Blockchain, Pudong Notary Chain and China Time Service Center simultaneously. After all are successful, a certificate of deposit with the corresponding LOGO will be obtained. The HASH fingerprint data of the work files that are completely consistent on each chain and platform shows the validity and non-tamperability of this certificate.

5. Log in to Hanghu Court to submit a complaint and verify the legality of the evidence

The judicial chain is a specific application case of Ant Blockchain BaaS. Ant Blockchain BaaS (Blockchain as a Service) is an open "blockchain as a service" platform based on the Ant Financial Alliance blockchain technology and Alibaba Cloud. It outputs blockchain as a cloud service, supports numerous business scenarios and on-chain data traffic, and is the foundation of industry blockchain solutions. Ant Blockchain BaaS is committed to building an open and collaborative platform to provide convenient services to enterprises and individuals around the world.

The picture above is the product map of Ant Blockchain, in which the technical architecture of BaaS is mainly divided into three layers:

1. The bottom layer is BaaS Core

The BaaS Core layer is based on A cloud resource management platform that provides flexible support for hosts and containers, enabling convenient cross-platform operation and deployment. For trusted hardware, Alibaba Cloud's Shenlong server provides corresponding hardware services and can provide a trusted execution environment with high reliability and high privacy protection. In addition to the certificate deposit platform and smart contract platform, heterogeneous chain cross-chain services will be launched soon on the basis of homogeneous chain cross-chain services. In the current market, a single chain or a single chain has its own limitations. In the future, cross-chain technology will become a very important part of establishing trust infrastructure and a mutual trust ecosystem. At present, the BaaS platform has achieved internal interconnection through cross-chain services. It can also access trusted data sources on the external Internet through smart contracts and cross-chain services. In addition, BaaS Core has corresponding functions and support for other basic capabilities, such as alliance management, security and privacy, certificate key management, etc. While providing the self-developed Ant blockchain system, the BaaS platform also supports open source systems to better meet the diverse needs of customers, including enterprise Ethereum Quorum and Hyperledger Fabric.

2. The upper layer is BaaS Plus

The BaaS Plus layer encapsulates and services the underlying services and capabilities, and opens them into standardized interfaces to provide partners with access and use. This can greatly reduce customers' investment in basic resources and significantly shorten the time it takes to access services. So far, the platform has launched services such as trusted certificates, universal traceability, real person certification, and enterprise certification, and will gradually launch more services in the future.

3. The top layer is the BaaS Marketplace and solutions

Ant’s many partners can provide their capabilities in the marketplace. At the same time, practical applications implemented in different scenarios will precipitate a set of standard application solution templates, making it easier for customers to learn from the platform capabilities of other similar scenarios in their own applications. The Pudong Notary Office data storage platform can become a member of the BaaS Marketplace.

1. Account system

All transaction operations on Ant Blockchain are carried out around the account system, so before sending and executing transactions, you need to ensure that you have created a corresponding transaction in Ant Blockchain account, and then you can use the created account to submit transactions, and you can also complete modifications to the relevant account configuration based on the account structure.

The specific account data structure model fields and descriptions are as follows:

Among them, the account contains three types of keys:

Ant Blockchain adopts the method of decoupling the account and the key to prevent the loss of the key to a certain extent. This brings security risks such as data loss on the chain. The main account operations supported by Ant Blockchain include:

2. Privacy protection

Ant Blockchain supports the privacy protection capabilities of sensitive account information data by introducing some features of cryptography. , by extending the relevant command functions at the smart contract level to realize the encrypted storage and addition and subtraction operations of the amount in the smart contract. Only individuals who obtain a valid key can decrypt the sensitive data in the smart contract and view the original amount information.

At present, the cryptographic features introduced by Ant Blockchain include zero-knowledge proof, that is, by introducing zero-knowledge proof, the legality of the transfer amount can be proved under the condition of encrypted ciphertext.

3. Cross-chain services

Ant Blockchain cross-chain service is an on-chain data service provided for smart contracts. This service deploys cross-chain services in the customer's blockchain environment. Contract/chain code, and provides an API interface for user contracts/chain codes to call and use. The cross-link service currently provides two types of services: ledger data access and contract message push, and their corresponding API interfaces. The ledger data access service can help user smart contracts obtain data on other blockchain ledgers, including but not limited to block headers, complete blocks, transactions, etc. The contract message push service can help communicate messages between smart contracts on different blockchains that have deployed cross-chain data services, satisfying scenarios such as cross-chain business association processing.

On May 22, 2019, Shanghai No. 1 Intermediate People's Court, Hangzhou Internet Court, Hefei Intermediate People's Court, Suzhou Intermediate People's Court, and Wuhu, Anhui Province jointly signed a letter of intent for cooperation, and will use the Hangzhou Internet Relying on the court's judicial blockchain platform, the four places are interconnected and jointly build the Yangtze River Delta judicial chain, creating a judicial-level trust mechanism with "full process records, full link credibility, and full node witness" to jointly promote judicial integration in the Yangtze River Delta region. develop. It was introduced at the meeting that the judicial blockchain operating mechanism of the Hangzhou Internet Court has become increasingly mature, and has collected 390 million pieces of electronic data. The dismissal rate of relevant cases has reached more than 96%. In intellectual property protection, financial risk prevention, agricultural product traceability, credit system construction, etc. played an important role.
The technology provider of the judicial chain of Hangzhou Internet Court is Ant Financial Blockchain, which has the world's leading core patented technology, 20,000 TPS high-performance certificate storage capabilities, extremely high privacy security protection capabilities, and top-level security Prevention and control capabilities protect the judicial chain. Its Ant Blockchain trusted certificate storage platform supports third parties to access the judicial chain.

For example, in terms of specific aspects, the judicial chain has greatly improved the effect of users' rights protection. For example, in China, copyright protection is very backward. For example, only 5% of the pictures are genuine, and the rest arePiracy, but the first instance of rights protection takes 8 months from filing to trial, and the compensation obtained is only 500-600 yuan, but the time cost and economic cost far exceed the compensation amount. However, the emergence of the judicial chain can reduce the cost of rights protection by one to two orders of magnitude. Secondly, the judicial chain can enhance the trust of the brand. On the one hand, it allows enterprises to stand together with the judicial chain and the brands and platforms recognized by the government. On the other hand, it allows enterprises to clearly and transparently tell their business models through trust connection. users, giving users a very strong sense of trust. Entrepreneurs, in particular, can have huge traffic in the early stages. Finally, the judicial chain solves the problem of the last mile of the Internet, which greatly reduces the user's cost of use. Therefore, using the judicial chain model really upgrades the traditional business model into a trust business model.

⑹ How to view the blockchain technology combined with Shimai Technology

The core of blockchain lies in consensus. Successful blockchain projects must obtain the recognition of more people, so The development of blockchain ultimately benefits the people. Making people's lives more convenient and simpler is the true meaning of blockchain technology. Hangzhou Shimai Technology is such an innovative company that applies blockchain technology in practical applications to benefit the general public.

⑺ What is blockchain and how to introduce blockchain in a simple and easy-to-understand manner

Blockchain is a term in the field of information technology.

Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". . Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". On October 24, 2019, during the 18th collective study session of the Political Bureau of the CPC Central Committee, General Secretary Xi Jinping emphasized, “use blockchain as an important breakthrough for independent innovation of core technologies” and “accelerate the development of blockchain technology and industrial innovation.” . "Blockchain" has entered the public eye and become the focus of society.

On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Biwenqiezi".

(7) Introduction to Hangzhou Blockchain Project Extended Reading:

Blockchain Financial Application:

Since 2016, Major financial giants have also taken notice and launched blockchain innovation projects one after another to explore its application in various financial scenarios.The possibilities of blockchain technology. In particular, Puyin Group took the lead in pioneering the “blockchain+” standard digital currency.

The standard digital currency is an asset that has been identified, evaluated, confirmed, insured, etc. by a third-party organization and written into the blockchain through rigorous digital algorithms to form a standard correspondence between the asset and the digital currency. relationship, called a standard digital currency.

In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations of people have been striving for, Puyin Group will Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou on the 9th;

At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the relationship between blockchain services and blockchain services will be discussed. The application of social public industries will be discussed. This conference will mark the beginning of the application of blockchain finance and the transformation and development of a new financial ecosystem.

⑻ Charity projects in Hangzhou can be uploaded to the blockchain. What are the benefits of uploading to the blockchain< /p>

The current biggest pain point in social charity and public welfare undertakings is “trust”. The sources and whereabouts of donations from charities lack supervision and independent third-party audits. Problems such as concealment of donation amounts and excessive purchases frequently occur, causing charities to lose public trust over a period of time. The emergence of blockchain is undoubtedly a redemption opportunity for charity work with low credibility. When charity is coupled with traceable blockchain, it can become completely new, fair and transparent.

Applying blockchain technology to charity can play a lot of regulatory roles. A report released by the American Charitable Aid Foundation mentioned that blockchain technology can change the way the public contributes to charity and effectively solve many problems in charity. Blockchain + charity will bring good news to all suffering people, and 100% of all donations will reach the final beneficiaries.

Blockchain technology is quietly changing charitable organizations. Some charities have been exploring this concept with some success. In the future, with the support of gradually improving blockchain technology, perhaps there will no longer be suspicions and disputes in charity work, so that people in need can receive help, and kind people will not be deceived. Charity can truly make people feel true, good, and beautiful. On Tracks. Let more people who need help get out of trouble as soon as possible!

⑼ How can blockchain cover other industries besides finance?

Blockchain is one of the most challenging innovations in the field of financial technology (Fintech) because blockchain Fundamentally subverting the inherent logic, operating model and business scope of traditional finance, breaking through the limitations of countless conventions, and entering a series of new application fields that were previously unreachable.
Blockchain is called a disruptive technology that will reshape Internet finance and even the entireIt is a key underlying infrastructure of the financial industry, and its value in the financial field is waiting for people to discover. Specific applications are as follows:
1. Applications in the banking industry
Wallet and payment are the first areas where blockchain technology has been involved, but this is also the traditional business scope of the banking industry. What changes can the arrival of blockchain technology bring?
Cross-border payment - application case:
Circle Circle, founded in October 2013, aims to make Bitcoin "simple and easy to operate, similar to Gmail (Google Mail), Skype (Microsoft's Internet phone) and other customers service tools like that” and the company quickly received a large amount of financing. In mid-2014, it received an investment of US$27 million, becoming one of the most well-funded companies in the field of digital cryptocurrency.
In 2015, Goldman Sachs and IDG Capital Partners led the investment, raising $50 million in funding for Circle. In June 2016, Circle received US$60 million in investment led by Chinese investors, and announced that it had established an independent company in China, Circle China, established a local team, and reached strategic cooperation with Internet and Everbright.
Circle utilizes Bitcoin blockchain transactions to provide instant and free fund transfers around the world. Circle hopes to use Bitcoin as a free Internet payment network to enable the smooth flow of national legal currencies around the world without any hindrance. By partnering with overseas companies like IDG, Circle can provide financial services to users using legal currencies in various countries.
Despite the complex regulatory structures of payment systems in various countries, cooperation between these countries has made progress. In April 2016, Circle received the first electronic currency license issued by the British Financial Conduct Authority (FCA), which attracted widespread attention in the industry. Subsequently, Circle announced the establishment of a partnership with Barclays Bank and officially entered the British market. Since then, British consumers can enjoy services such as fast transfer payments and Bitcoin buying and selling like American consumers.
In order to make it more convenient for users, Circle cooperates with Apple. In the iOS 10 system, Apple’s iMessage supports users to use Circle’s Bitcoin payment system. Jeremy Allaire, CEO of Circle, said:
“Consumers will benefit from iMessage allowing payment services to be connected. It would be difficult to install an APP alone for payment and share it with friends. Transfer payments between places also require a complex setup process, but directly connecting to the iMessage service is much simpler.”
On September 13, 2016, Circle announced that users can pay to anyone in the world through iMessage. people.
The advantages of blockchain in cross-border payments: Low cost, real-time transactions, and high security.
Smart Bills—Application Case:
Complex Beauty Blockchain Bill Project Bills and blockchain technology can be well combined. After adopting the decentralized distributed ledger of blockchain, it has changed the current situation. Some system storage and transmission structures have established a more secure operating mode to solve the problem of counterfeit bills.
The process of the bill from its creation to its demise is completely reflected through the timestamp. Its history can be traced, which makes this model have a new continuous endorsement mechanism and truly reflects the transfer process of the rights of the bill.
The domestic Hangzhou Complex Beauty Blockchain Research Center has also initially developed an open source project for a blockchain lending bill exchange based on Ethereum, which integrates multiple segments such as finance, catering, business management, and express delivery tracking. The concept of applying blockchain technology in the field. As shown in the figure, the open source project of the Complex American Blockchain Network Lending Exchange is an online lending exchange that applies blockchain technology and can complete online transactions claiming to be 150,000 per second with no handling fees.
Blockchain-based bill business has four advantages:
From the perspective of moral hazard, "one vote sells more" in paper bills and the payment and endorsement in electronic bills are not synchronized from time to time. However, due to the non-tamperable timestamp and the publicity of the entire network, the blockchain will not cause any defaults once the transaction is made, regardless of whether it is a paper ticket or an electronic ticket.
From the perspective of operational risks, since the electronic bill system is operated in a centralized manner, once there is a problem with the central server, it will have catastrophic consequences for the entire market. At the same time, the access to corporate online banking will transfer more risks to Regarding the bank’s own network security issues, the entire chain of risks will become longer and longer. With the help of distributed high fault tolerance and asymmetric encryption algorithms in the blockchain, the risk caused by human operations will be almost zero.
From the perspective of credit risk, the collection and assessment of the credit of all participants can be achieved with the help of blockchain data, and real-time control can be carried out.
From the perspective of market risk, a large number of asset mismatches in the intermediary market not only lead to their own losses, but also tie up the interests of banks. The programmability of the blockchain can not only effectively control the balance of the assets and liabilities of participants , and can also rely on the characteristics of data transparency to promote the authenticity of the entire market transaction price response to capital demand, thereby forming a more realistic price index, which is conducive to controlling market risks.
Bank settlement - application case: VISA
Bank settlement refers to the act of collection and payment through the transfer of funds in a bank account, that is, the bank accepts the entrustment of the customer to collect and pay on behalf of the customer, and transfers the money from the deposit account of the paying unit , transferred to the deposit account of the receiving unit to complete the settlement of claims and debts between customers or the allocation of funds. In this process, banks serve as both a medium for commodity exchange and an intermediary for clearing funds in social and economic activities.
Unlike domestic banks, which mainly rely on the difference between deposits and loans to make profits, half of the profits of multinational banks come from intermediary settlement business. For them, if they open up new business areas and reasonablyReducing settlement costs is directly related to its fundamentals.
VISA is the world's largest credit card company. There is no doubt that the rise of digital cryptocurrency will inevitably have an impact on its credit card payment business. However, VISA has not always been resistant to electronic currency and blockchain, but has adopted an open attitude.
In October 2015, VISA and DocuSign jointly launched a "proof of concept" project using the Bitcoin blockchain to record and store car rental data. The project combines DocuSign’s digital transaction management (DTM) platform and electronic signature solutions with VISA’s secure payment technology. It allows consumers to configure rental, insurance and other daily purchases in the car, such as parking fees and tolls, and users can pay directly with VISA cards.
Peripheral applications do not satisfy VISA. In the same year, VISA cooperated with Coinbase to launch the first Bitcoin debit card that can be used in the United States. On November 30, at the UnBound conference in London, the VISA European Innovation Laboratory demonstrated a "proof of concept" remittance application through which people can remit money on the Bitcoin blockchain.
In September 2016, VISA launched Interbit, an inter-bank settlement and payment system based on blockchain technology in cooperation with digital payment startup BTL Group, to evaluate whether blockchain technology can facilitate international transfers between banks. Reduce costs, settlement time and credit risk.
A series of major actions in the past two years can be seen: VISA has begun to realize the value of blockchain technology and is working hard to make blockchain technology a powerful tool to expand its sphere of influence.
The advantages of blockchain in bank settlement: safe, convenient and intelligent.
In addition to using blockchain technology to transform existing businesses, major banks around the world have also launched their own encrypted digital currency plans to reduce their operating costs.
Advantages of blockchain in banking digital currency: reducing costs.
2. Securities investment market application
Securities trading - application case: Linq
The securities trading market is an important application field of blockchain. The application of blockchain technology can not only speed up clearing and settlement, but also reduce the number of books that financial institutions need to maintain and ensure more accurate audit trails.
NASDAQ is the earliest pioneer in the securities exchange market. In the second half of 2015, it launched Linq, a trading platform based on Bitcoin trading technology for trading of primary market companies. As shown in the figure below, Linq can record equity transactions before a company's IPO. It can track corporate equity transactions, shareholder and investor information, etc., and is very valuable for asset analysis in the private equity market.
Nasdaq Blockchain Strategy Leader FuFredrik Voss is convinced that the high efficiency provided by blockchain technology will greatly enhance Linq’s advantages as a private equity trading platform. So far, there is no technology that can truly keep people away from paper work, and blockchain technology will make it a big step forward, significantly reducing the possibility of errors compared to manual processing.
The advantages of blockchain in securities transactions: speed up settlement, simplify accounts, and facilitate tracking and auditing.
Equity Crowdfunding - Application Case: Xiaoyi
Funding has always been a gap between creative ideas and entrepreneurship, and it was this gap that gave birth to the world's first crowdfunding platform - Kickstarter. The way Kickstarter works is a typical platform business model. The users of the platform are on one side people who are eager to create and create, and on the other side are people who have some funds and are willing to fund new ideas. Both parties share the same desire. They all hope that new ideas will become reality and achieve continuous promotion.
Crowdfunding platforms based on blockchain technology can raise funds by creating their own digital cryptocurrency or digital assets, and by distributing their own "digital equity" to early backers, investors receive support for startups. Certificate of shares.
Blockchain crowdfunding platforms usually have a three-layer structure:
The lowest layer is the blockchain network, which builds a decentralized distributed ledger;
The middle layer is business logic Combined with the blockchain, we jointly establish an account center, equity registration, equity certificates, equity transactions, equity management and other functions;
The top layer provides services to customers of various crowdfunding platforms.
In China, Xiaoyi is the first company to use blockchain technology to register company equity. Although this is an innovation, it is not easy to achieve compliance with Chinese laws and connect with the physical world in terms of underlying logic and various details. After in-depth research and analysis of my country’s current legal environment, Xiaoyi has the potential to become a practical blockchain application.
Xiaoyi is a blockchain protocol based on blockchain technology that registers, issues, manages, and trades various equity shares through a peer-to-peer network. In the early stage, the equity of unlisted companies will be used as the entry point to provide digital share incentive solutions for startups and equity management solutions for equity crowdfunding companies. In the future, it will transition to tradable equity, that is, "blockchain IPO", which will gradually become blurred. The boundary between unlisted companies and listed companies.
The advantages of blockchain in equity crowdfunding: transcending time and space constraints, optimizing crowdfunding organization, and rational distribution of equity and interests.
3. Application in Insurance Industry
Policy Sales—Application Case: Bubi Aviation Accident Insurance
Traditional aviation accident insurance has always had problems such as insurance fraud and price hikes by intermediaries. As the saying goes, "the wool comes from the sheep", it is ultimately passed on to consumers. Blockchain technology can provide effective means to solve these problems.
On July 29, 2016, Bubi Blockchain cooperated with Sunshine Insurance to launch the "Blockchain + Aviation Accident Insurance Card", which is the first domestically placed mainstream financial assets on the blockchain. circulation.
Most aviation accident insurance will only make claims when an aircraft accident occurs, so in most cases it is not easy to detect when customers buy fake insurance. In order to prevent the purchase of "fake insurance policies", Bubi Blockchain relies on its multi-party data sharing characteristics to trace the entire process of card slips from the source to the customer. All parties can not only check the authenticity of the card slips, but also ensure that the card slips are authentic. The authenticity of the order can also facilitate subsequent processes, such as claims settlement, etc.
In order to prevent middlemen from raising prices and passing them on to consumers, aviation accident insurance cards are set up on the Bubi blockchain. Without middlemen, the price of insurance cards will drop significantly. According to data, this product can be purchased for 60 yuan per copy and can be used by 20 people. Each time, you can get aviation accident protection of up to 2 million yuan, which is equivalent to spending 3 yuan each time to get 2 million yuan of protection.
The advantages of blockchain in the insurance industry: authenticity and transparency, information security, traceability, clear claims process, and low cost.
