1. In recent years, a large number of intellectual property infringement cases have emerged. I heard that blockchain can be used to store evidence and collect evidence. Does the country recognize blockchain-related evidence?

Recognized of. The State Intellectual Property Office made it clear in its reply to the "Request for Instructions on the Effectiveness of Blockchain Electronic Evidence in Patent Administrative Adjudication Cases" submitted by the Zhejiang Provincial Intellectual Property Office: In administrative adjudication, if a party submits blockchain and other related electronic evidence , can refer to relevant regulations for identification. Recently, Feiluoyin, a one-stop data value protection platform under Qulian Technology, officially launched the only official blockchain certificate in the field of intellectual property in the country, "Zhejiang Province Intellectual Property Blockchain Certificate". The certificate is based on the most influential one in the Yangtze River Delta. The judicial service alliance chain "Imprint Chain" is jointly issued by the Zhejiang Provincial Intellectual Property Research and Service Center and the notary nodes on the chain to provide open, convenient and authoritative blockchain intellectual property certificate confirmation services to the society.

2. Is blockchain a pyramid scheme? Is blockchain a disguised pyramid scheme?

Blockchain is a new technology and is not a disguised pyramid scheme. It is just claimed by many pyramid schemes to be "district schemes". "Blockchain" actually does not have any technology, it is just a pyramid scheme in the name of "blockchain". The country has issued multiple announcements to crack down on this type of pyramid scheme. The following is Xinhuanet's report on blockchain MLM:

Blockchain is not equivalent to virtual currency, and there are also security risks. Behind the popularity, there are exaggerated publicity campaigns with "ulterior motives". Only by removing the flashiness can the blockchain return to its true application value.

Invest 80,000 yuan and it will become 800,000 yuan in three months? Shenzhen police uncovered a huge fund-raising fraud case. Under the guise of blockchain concepts and 10 times earnings, thousands of investors have fallen into it, with the amount involved reaching 307 million yuan. Under the "mysterious veil" of the blockchain, criminals have taken advantage of the opportunity to use their tricks, and the blockchain has become a "signature" for economic crimes such as fraud and pyramid schemes.

Why has the blockchain been repeatedly “misused” by illegal activities such as pyramid schemes and fraud? Apart from being “unclear”, what is the “function” of blockchain technology itself? Since the beginning of this year, with the intensification of supervision and the cooling of the trend of currency speculation, new opportunities have been brought to the development of blockchain. How is the implementation of blockchain commercial "applications" now? Reporters from "Lookout" News Weekly recently conducted an investigation into this.

When the three-month "fund release period" promised by the trading platform expired and the staff started "kicking" people in the QQ group, Tang Haiyan, who lives in Bao'an District, Shenzhen, realized that she might have been cheated. .

Previously, Tang Haiyan invested 80,000 yuan to buy a virtual currency called "Puyin Coin" under the introduction of a classmate. "The other party said that this currency is the most advanced blockchain technology at the moment, with Tibetan tea as collateral, and he also showed me a 'technical white paper'. I didn't understand blockchain, so I didn't read it carefully."

Although he doesn’t know much about blockchain or virtual currencies, Tang Haiyan is full of expectations for the high investment returns. She told reporters that the company that issued the "common silver coin" would regularly press 1 for the virtual currency.Split at a ratio of 10, which means that each split will increase the value of the "common silver coins" in the hands of investors by 10 times. As long as it is split once, the 80,000 yuan she invested is equivalent to buying "common silver coins" worth 800,000 yuan, and she can get huge profits by selling them on the trading platform.

According to the rules of the trading platform, the "common silver coins" just purchased cannot be traded immediately. They must be frozen on the platform for three months before the "release period" can begin. However, when three months passed, Tang Haiyan not only failed to double her assets, but also the 80,000 yuan frozen on the platform could no longer be used for transactions.

“Other investors began to question the authenticity of this investment in the QQ group. As a result, the company staff kicked these investors out one by one. I felt bad.” She said.

Facts also proved Tang Haiyan’s intuition. At the end of March 2018, Shenzhen police uncovered a huge fund-raising fraud case, with the amount of fraudulent funds reaching 307 million yuan. In this case, the Shenzhen Puyin Blockchain Group Co., Ltd. involved in the case used the "blockchain + Tibetan Tea" model to issue virtual currency and defraud public deposits. Tang Haiyan was one of thousands of victims. .

An investigation by the Shenzhen police found that the company claimed that investors could trade "common silver coins" on the virtual trading platform "Jubi.com" to earn the price difference

. In fact, the change in its buying and selling price was caused by the company using investors' investment funds to perform behind-the-scenes operations, and once raised the price of "common silver coins" from 0.5 yuan to 10 yuan, allowing investors to taste some sweetness. When a large number of investors entered the market, the company continued to cash out by maliciously manipulating the price trend of "Common Silver Coins", which eventually resulted in the "Common Silver Coins" in the hands of investors being worthless.

Since 2018, engaging in fraud and pyramid schemes under the banner of blockchain has become a commonly used "routine" in new criminal methods. In April 2018, Jinan police busted a pyramid scheme gang under the guise of "western development", "national poverty alleviation", "original stocks", "blockchain" and "e-commerce", arrested more than ten main suspects, and froze the funds involved in the case There were more than 100 accounts, and more than 300 million yuan of funds involved were seized.

Jinan police said that Huileyi e-commerce company designed fake virtual disks on the Internet and released so-called "treasure coins" and "precious coins" on the grounds that the country is vigorously developing the big data industry. and other virtual currencies.

They first use the gift as a guise to give a certain amount of virtual currency to newly joined MLM personnel, with the price of each coin being tens of yuan, and then through artificial manipulation, the virtual currency will rise to more than 100 yuan or even hundreds of yuan. Yuan, attracting people who do not know the truth to join, and finally "cut leeks" through the cyclical fluctuations of the so-called "devaluation" of virtual currencies, repeated over and over again, and ultimately achieve the purpose of seeking illegal benefits.

In Xi'an, the local police also successfully cracked a huge online pyramid scheme under the banner of blockchain. According to the police, the criminal suspect Zheng paid a high salary to organize network platform administrators Zhang, Li and other 9 people to commit suicide.Starting from March 28, 2018, through collective pyramid schemes and online pyramid schemes, virtual "Datang Coins" were sold on the "Consumption Era" online platform at a price of 3 yuan each, and the appreciation rate was manipulated;

< p> At the same time, promotion meetings were held in many cities at home and abroad to attract members, and 28 levels of agents were set up according to the development of members and offline. In just 18 days, the group developed a total of more than 13,000 registered members. It has been identified that the case is involved 31 provinces, municipalities and autonomous regions across the country, involving more than 86 million yuan in funds.

The "Tencent 2017 MLM Situation Awareness White Paper" released by Tencent Security Joint Laboratory stated that in recent times, various overseas capital disks, virtual currencies, ICO (blockchain project initial public offering of tokens) Financing) projects emerge in an endless stream, which hide many risks such as illegal issuance, false projects, cross-border money laundering, fraud, pyramid schemes, etc., causing a large amount of funds to flow overseas. Once they collapse, run away, or lose contact, investors often have no way to complain and lose money. recover. For example, Baichuan Coin, Mark Coin, Beta Coin, Dark Coin, etc.

Reporters from "Lookout" News Weekly conducted interviews in Guangdong, Shandong, Shanghai and other places and learned that most people know that the concept of blockchain is very popular, but they are "uninformed" about the specific functions of blockchain. There are different opinions: some people think it is used for "investment and financial management" and "buying and selling currency", while others think it is "a major invention of the same magnitude as the steam engine". Some entrepreneurs are gearing up to seize this "once-in-a-lifetime opportunity to get rich."

Many people in the industry said that it is precisely because people have many misunderstandings about blockchain that criminals have the opportunity to fish in troubled waters and mislead investors.

First, blockchain is not equal to virtual currency. As of the end of last year, the number of domestic ICO participants and total transaction volume had doubled. A large number of digital currency exchanges have fled overseas, and the agency investment model has involved more ordinary people in high-risk investments.

Many industry self-media and famous speakers have formed interest alliances with issuers, digital exchanges, etc. to endorse the "Air Coin" project platform and create public opinion. In December last year, the People's Bank of China and nine other departments characterized ICOs as "suspected of illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities."

During the interview, many people told our reporter that the existence of tokens has built a set of equity mechanisms for the development of blockchain technology. This mechanism is indispensable for stimulating the prosperity of blockchain applications. of. "Market practice in the past five years has proven that blockchain applications without equity mechanisms are like computers without Internet connectivity and a market economy without currency. The application scenarios and development speed are greatly reduced." said an investor in Shanghai. .

In fact, tokens represented by Bitcoin are only one of the earliest products to verify blockchain technology. There is no equivalence between the two, and the existence of tokens has already affected the blockchain technology. The development of the chain has obvious negative effects.

Currently, more and more people in the industry are beginning to think about whether the development of blockchain must rely on the issuance of tokens to achieve incentives.. Guo Dagang, secretary-general of the Beijing Internet Finance Industry Association, told this reporter that the so-called incentive mechanism is just a theoretical basis for project parties to issue tokens.

Secondly, blockchain is not omnipotent and there are risks in its security. Blockchain is generally considered to be able to achieve three functions:

First, the data stored on the blockchain cannot be tampered with or forged, and the data has high credibility and credibility; second, The entire transaction process is traceable, enabling accurate tracking of responsibilities; third, smart contracts embedded in the blockchain can be automatically executed based on the contract, thereby improving work efficiency and reducing the risk of default. The industry generally believes that blockchain has broad application prospects in finance, logistics, trade and other fields.

In fact, blockchain is not omnipotent, and its functions also have many limitations. It is generally believed that based on its cryptographic characteristics, if you want to tamper or forge on the blockchain, you theoretically need to control more than 51% of the nodes to achieve it. When there are enough nodes in the blockchain, this trust creation mechanism with widespread public participation will be difficult to tamper with.

However, in reality, digital currency exchanges are frequently attacked or even stolen. On June 20, 2018, South Korea's Bithumb exchange announced on its official website that the exchange was attacked by hackers and cryptocurrency worth 35 billion won, or approximately US$32 million, was stolen.

Ji Xinhua, known as China's first generation "hacker", said that the blockchain will continue to face attacks, and the process of uploading data to the chain is prone to information leakage. Some people in the industry are also worried that once the super computing power of quantum computing is realized, it will also have a direct impact on the blockchain.

Thirdly, the popularity of blockchain is not entirely true. Data shows that from the end of 2017 to the beginning of 2018, more than 300 self-media companies mainly focused on ICO projects appeared, which became an abnormal phenomenon worth noting.

(2) Extended reading on Bhcv Fish Paradise Blockchain Case:

On August 24, 2018, the China Banking and Insurance Regulatory Commission website released a risk A reminder to remind the general public to guard against illegal fund-raising in the name of "virtual currency" and "blockchain".

The original text is as follows:

"Risk Tips on Preventing Illegal Fund-raising in the Name of "Virtual Currency" and "Blockchain""

China Banking and Insurance Regulatory Commission, Central Network The Office of Information Technology, the Ministry of Public Security, the People's Bank of China, and the State Administration for Market Regulation remind:

Recently, some criminals have issued so-called "virtual currencies" and "virtual assets" under the banner of "financial innovation" and "blockchain". ""Digital assets" and other methods absorb funds and infringe on the legitimate rights and interests of the public. Such activities are not really based on blockchain technology, but are actually hyping up the blockchain concept to conduct illegal fund-raising, pyramid schemes, and fraud. They mainly have the following characteristics:

1. Obvious networking and cross-borderization. Relying on the Internet and chat tools for transactions, and using online payment tools to receive and disburse funds, risks have a wide scope and spread quickly. some don'tCriminals rent overseas servers to build websites, essentially carry out activities for domestic residents, and remotely control and carry out illegal activities.

Some individuals claim in chat tool groups that they have obtained investment quotas for high-quality overseas blockchain projects and can invest on their behalf, which is most likely a fraudulent activity. Most of the funds for these illegal activities flow overseas, making supervision and tracking very difficult.

2. Strong deception, temptation and concealment. They use hot concepts to create hype and fabricate numerous "high-level" theories. Some even use celebrity V's "platform" propaganda, and use airdrops of "candy" as temptations, claiming that "currency values ​​only rise but not fall" and "the investment cycle is short. "High returns, low risks", which is highly deceptive.

In actual operation, criminals illegally make huge profits by manipulating the price trend of so-called virtual currencies behind the scenes and setting profit and withdrawal thresholds. In addition, some criminals also issue tokens in innovative forms such as ICO, IFO, and IEO, or conduct virtual currency speculation in the form of IMO under the banner of the sharing economy, which is highly concealed and deceptive.

3. There are various illegal risks. Through publicity, criminals use "static returns" (profits from currency appreciation) and "dynamic returns" (profits from offline development) as bait to attract the public to invest funds, and induce investors and development personnel to join in, constantly expanding the capital pool. , with characteristics of illegal fund-raising, pyramid schemes, fraud and other illegal activities.

Such activities use "financial innovation" as a gimmick, but are essentially a Ponzi scheme of "borrowing new and repaying old", making it difficult to maintain long-term capital operations. The general public is requested to view the blockchain rationally, do not blindly believe in promises made by the public, establish correct currency concepts and investment concepts, and effectively improve risk awareness; they can actively report to relevant departments any clues about illegal crimes discovered.

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

According to Hangzhou Daily, on September 18, 2018, 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.

AidQuoting from the analysis of the "Blockchain Judicial Evidence Application White Paper" of 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 role of electronic evidence in judicial practice The specific forms of expression 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 results in many limitations in litigation cases.

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. Who advocates the general principle of allocating the burden of proof?, whoever provides evidence will bear the consequences of losing the case if he cannot provide evidence. 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 original documents, 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 changed greatly. This is called the second curve. The original object of connection was information, but now it is 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 isVery difficult to deal with.

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 methods 20 years ago, the current Internet connection is 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. , 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 legal When connecting, 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, it is a bubble. It has a certain market when it is relatively large, but once it encounters real value, it breaks down;

The fourth type is the judicial chain, which can be summarized in 15 words, that is, the whole process record, the whole chain The road is trustworthy 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 of Alipay's birth started with guaranteed transactions, solving the problem of the authenticity of previous transactions between buyers and sellers. Later, based on paymentBao, proposed Sesame Credit. Many people have Sesame Credit points. Through past credit records, it provides big data and artificial intelligence references for users to fulfill their obligations, 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 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 low cost. 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, using blockchain technologyIt is a consortium chain that connects notary offices, CA/RA institutions, judicial appraisal centers and courts, 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 litigation process, the "data ID card" that has been saved on the electronic evidence platform will be automatically compared with the original electronic data to determine whether the electronic evidence has been tampered with later, thus 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 institutions, notary institutions, filing institutions) 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.

In order to open up the mutual legal chain of HangzhouTaking the Shanghai Pudong Notary Office's data storage platform 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 above picture 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. On offerAt the same time as the independently 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, accounts contain three types of keys:

Ant Blockchain adopts the account It is implemented in a decoupled manner from the key, which to a certain extent prevents security risks such as data loss on the chain caused by key loss. 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. Cross-link service currently providesProvides 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 to jointly build the Yangtze River Delta judicial chain, create 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%. 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 are pirated. However, from the filing of the case to the trial, the first instance takes 8 months, 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 enables 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.

4. Frontier of science and technologyFar more than blockchain

Looking at the future based on actual data is more down-to-earth, rather than some relatively empty discussions. Only by obtaining more forward-looking data can we have a more insightful understanding of future development.

In fact, in addition to blockchain, other technological frontiers are also worthy of our careful observation.
As shown in the picture:

The 3x speed law of technology waves - that is, when the number of blog posts on new technology directions increases by more than 3 times every year, this The technical direction was accepted by the developer community.

For example, the time when deep learning more than tripled was in 2015, Ethereum was in 2017, and the Internet of Things was in 2018. What does it mean? This means that blockchain has indeed made great progress in the past year, and the Internet of Things is likely to be a new trend in the next year.

The trend chart on the right is based on the number of developers in the community. From 2015 to 2017, the number of developers engaged in artificial intelligence and The number of TensorFlow-related developers has increased by nearly 4 times. This is from a quantitative perspective. We can see that the development of artificial intelligence in the future will be very rapid. We can see that the number of blockchain blogs has increased nearly three times that of last year, while Ethereum has more than six times that of last year. This shows that there is still room for blockchain technology.

Therefore, it is most valuable to find ways to obtain well-founded data to enhance your ability to see through the bubble phenomenon!

First, Bitcoin has its meaning and value.

Because it is the first virtual currency, the first one will allow the public to form a recognized value and credit, it can be anti-counterfeiting, it can be strictly scarce, it can be infinitely divisible, these things When added up, it becomes a real currency. Just like gold, many people actually say why it is valuable because people believe it is valuable. That is, people's confidence in Bitcoin makes it valuable. ***

Second, blockchain is also valuable.

A/First of all, it is distributed and decentralized, which avoids many problems of a centralized system, the biggest of which is unfair problems such as centralized black-box operations.
In addition, because its accounting system can be authenticated, anti-counterfeiting, and traceable, it will also have many uses, the biggest of which isCreate fairness. In fact, blockchain seems to be technology on the surface, but it is actually human nature, and it is actually philosophy.

B/Blockchain is indeed very revolutionary - but it is just like the impetuous period before the emergence of Internet portals. Many people compare blockchain to the Internet era, but even in the Internet era, it was the early stage of the Internet, that is, the BBS period. Those who enter the market during this period may not be future winners. Study with peace of mind and watch the market. There are no opportunities that will directly come to you before you report. The so-called envy of fish in the ocean is better to retreat and build a net.

C/The entrepreneurial opportunities for blockchain projects are actually very small - small innovation does not mean that you can start a business. That's like a hyperlink on the Internet. Hyperlink is an amazing invention, and it is not an exaggeration to say that it created the glory of the Internet today, but no billionaires were born from it, but it only popularized its use and improved the efficiency of information exchange on the Internet.

D/Tulip bulb incident - the subsequent value of digital currency is questionable.

Blockchain entrepreneurs now seem to be full of impetuousness.
On the one hand, I am full of pride and feel that I am on the leading edge of the trend; on the other hand, I am also full of anxiety, hoping to make more money as soon as possible, and I am very eager for quick success and instant benefits. Blockchain entrepreneurs often start to quarrel, dispute, or even disappear after raising enough coins. This is a manifestation of the impetuousness of this industry.

Some people say that is not true. You see, there are still many currencies today that will increase many times in a short period of time, 10 times, 20 times, 100 times. In the famous bubble event "Tulip Ball Incident" that we all know, if you enter early and withdraw early, you will still make money; but human nature is that people who make money in impetuosity often do not make money early. Leave the market; but if you haven't left the market yet, you may encounter the day when the bubble bursts. But what exactly is a bubble? You still need to identify it yourself. If you listen to others, the probability of failure is much greater than if you listen to yourself! *

The embarrassing thing is that most people who think they are here now like to discuss currency issuance instead of discussing what applications are suitable for blockchain.
Here is an idea - online gambling. Due to its decentralized nature, no bookmaker can manipulate it, and the results cannot be faked at all. Moreover, encrypted digital currency is very convenient and hidden during transactions, making it fast and simple compared to existing traditional methods. It makes full use of the decentralized characteristics of the blockchain, so that everyone can be convinced by the results of your application on the blockchain. No matter what the result is, I believe it is completely fair and no one can manipulate it. Yes, I accepted it.

5. The country’s first case of using blockchain contract technology to open a casino was solved. How much effort was wasted in solving the case

The police took many measures in this operation Conducting network control on the ground, collecting criminal evidence, and conducting unified arrest operations, this major criminal gang that used blockchain contract technology to open a casino was uncovered in one fell swoop.

1. The police received an online report and found a suspect who used blockchain contract technology to gamble.

After locking in the criminal gang, the police conducted a thorough investigation of the suspect's relationship network and residence, and conducted covert investigations near the scene to identify the suspects scattered throughout the country. The whereabouts were summarized. After collecting the criminal evidence, in order to successfully arrest all the suspects during the operation and prevent any fish from slipping through the net, the police mobilized police from various places to determine the time for the unified arrest operation and strictly investigated the relevant traffic. At the exit of the main road, all the suspects were finally arrested, and various tools used to commit crimes such as computers, mobile phones, and bank cards were seized.

6. Shaoxing, Zhejiang sentenced the country’s first criminal case involving blockchain evidence

Between January 2017 and March 13, 2019, the defendant Wang Moumou was in Jiangsu Province , Zhejiang Province, Jiangxi Province and other places, they made up excuses such as "cannot find fellow villagers, lost their wallets" and other places, and used "borrowing" to defraud other people's property 176 times, totaling RMB 9,993.

There are many victims in this case, scattered across the country, and the single crime amount is small and large. If the relevant evidence is recorded in the form of traditional CD-ROMs and transferred between the police, prosecutors, and law, it will be possible Data loss occurs due to disc damage, or data in the disc is tampered with.

How to effectively encrypt and store electronic evidence has become the key to solving such problems. During the case handling process, the Shangyu District Judicial Authority teamed up with the Ant Blockchain team to encrypt the data with blockchain technology and ensure the authenticity of the evidence through later hash value comparison.

It is worth mentioning that the circulation and comparison of evidence in this case ran through the entire process of investigation, prosecution, and trial, and was unanimously recognized by the public security and prosecutorial agencies.

The relevant person in charge of the Criminal Division of Shangyu Court said, “Blockchain is a tamper-proof, traceable, and shared distributed ledger technology. The use of blockchain for encrypted certificate storage has been available as early as 2018. It has been confirmed by the Supreme People’s Court, and has been used in judgments in civil and commercial cases, but its application in criminal cases is the first in the country.”

The successful judgment of this case is a key to the use of blockchain. Technology for electronic data storage and review is of great significance. In the next stage, Shangyu Court will also actively explore "IOT+blockchain" technology with Ant Blockchain to build trusted data collection equipment and upload the data calculated by the equipment to the chain in real time to ensure storage and transmission.Ensure the authenticity, safety and reliability of the transmission link, and promote the authenticity of electronic data to extend to the source.

7. What happens when the court mediator terminates the mediation and uploads the mediation agreement of the case to the judicial blockchain?

Legally speaking, the mediation should be ended and the case should be heard in court. I mean, just consult a local professional lawyer to find out.

8. Fraud in the name of blockchain, and blockchain has become the "signature" of pyramid schemes.

Recently, fraud in the name of blockchain technology has been on the rise. potential. Some self-media and illegal coin issuance companies in the currency circle have become active again, using social software to promote tokens in an attempt to fish in troubled waters. Investing 100 yuan can earn 1 million. Have you ever seen this kind of profit return? What is talked about every night has been packaged as a "hen that lays golden eggs" because of the lofty concept of "blockchain". In real life, it has been exploited by criminals and succeeded repeatedly.

Blockchain has become the “signature” of MLM fraud

The popularity of blockchain technology has also led to some criminals who use the name of blockchain to commit MLM fraud. The line is back from the ashes. Guo Yuhang, chairman of the China Blockchain Application Research Center, told reporters that when he was conducting research in a province in central China recently, officials from the financial department of the province revealed that more than 40 illegal fund-raising cases under the banner of blockchain have been investigated and dealt with locally. The amount involved in one case was as high as more than 2 billion yuan.

Not long ago, a sports APP that claimed to be “developed based on blockchain technology” was investigated by relevant departments in Changsha City, Hunan Province. This software has been accused of being a "typical pyramid marketing model" and is the result of combining traditional MLM methods with new concepts such as "blockchain" and "big health".

Similar cases have occurred frequently this year. Fraud cases implemented in the name of blockchain have been uncovered in Suzhou, Yancheng and other places in Jiangsu Province. The police in Hengyang City, Hunan Province uncovered a fraud case in May this year. The criminal gang used blockchain as a gimmick to issue worthless "air coins" and raised nearly 350 million yuan worth of Ethereum.

In the exposed cases of pyramid schemes and fund-raising fraud under the guise of blockchain, the characteristics of "pulling people's heads" are very obvious. They often take advantage of the mentality of the public who are not familiar with blockchain but have heard of Bitcoin’s “wealth-making myth”, and put a “fashionable” cloak on illegal activities, promising low investment, high returns, and higher returns for offline development. Those who do not know the truth It’s easy to be fooled.

Industry experts said that although "Air Coin" may actually use blockchain technology, the purpose of issuance is too grand, such as "human health" and "reconstructing business models", and is almost useless. possible. Once investors are trapped and funds accumulate to a considerable amount, the project issuer will have a high probability of running away, and investors will lose their money. The resonance model that is popular in the currency circle in 2019 is a typical example. Typical projects with resonance models such as CXC and VDS have appeared in many places in my country, and many users have not recovered their own costs of funds invested. Next followsRegulation, it is only a matter of time before these projects are liquidated.

With this phenomenon of bad money driving out good money, we have to look beyond the appearance to see the essence

“There cannot be an equal sign between blockchain and Bitcoin, obviously it is not the same. It is not the same as 'getting rich.'" Many industry insiders emphasized to reporters that blockchain is an underlying technology, relying on which a number of digital currencies such as Bitcoin were born, but they cannot be confused together because of this. Discovering the truth requires penetrating the fog. In addition to increasing the popularization of blockchain knowledge so that the public can understand and identify pyramid schemes disguised as "blockchain", more importantly, supervision must also keep pace with the times. Although the supervision of digital currency speculation, spam issuance, and pyramid schemes has never been relaxed in recent years, traditional supervision methods currently face considerable difficulties due to the complexity of the blockchain concept and its legal blankness.

Experts pointed out that it is necessary to strengthen the application of regulatory technology. Most MLM projects in the name of blockchain will frequently spread and leave traces on the Internet. With the help of existing financial technology supervision methods, it is possible to detect and investigate in time.

Of course we can’t kill them all with one stick. We also need to learn how to distinguish the pros and cons of blockchain projects

There are good and bad in blockchain, and there are good and bad, so We must also be good at discovering high-quality projects and passing inferior projects. How to spot spam projects?

Significant characteristics of junk projects: For example, CXC, VDS, and the investigated Qubu Bao make money without losing money, attracting people to develop offline. Although many normal cryptocurrencies also need marketing and promotion, they also need publicity. The project has advantages and hopes to be known and used by more people, but publicity is publicity, and we will never promise to make a profit without losing any money, let alone promote it in a way that attracts people's hair to grow offline. But for empty shell MLM coins, the purpose is to make money, so we must paint you a beautiful money-making situation, and then directly or in disguised way, use the method of pulling people's hair to get offline to gather funds.

Of course, we must maintain high-quality projects, because in the early stages of an industry, high-quality projects can easily be inadvertently trampled by users with lower costs and unawareness, so we must maintain high-quality projects. , such as 2019 rookie SBO. Through the Star Leap Plan, SBO has created a stable ecosystem and built a complete closed-loop underlying infrastructure to contribute to the development of the digital economy and help the economy and society. The original SBO ecosystem has begun to be compatible with all DAPPs on the chain and facilitates development. Or transplant DPAA on other chains. At another investment level, SBO opens up the built-in trading function. Although SBO is not completely online now, based on this function, users can invest in SBO in advance, enjoy the blockchain dividends together, and explore future blockchain application models with SBO. There are already many users making money through SBO, so SBO has gathered very strong community forces to protect the development of SBO.

For the sake of users, SBO will also be delayed in listing on the exchange at this stage. With the tightening of national policies, there are many problems with the project currently being listed on the exchange. One is the "selling pressure problem", and a large number of users have The market will lead to the collapse of the project, and the other is "exchanges absconding with funds." Currently, many exchanges have problems. Under the heavy attack of the state, many exchanges have begun to swallow up user assets and transfer them overseas, so currently SBO cannot Listing on the exchange is a way to save the country. Usually from a long-term perspective, it protects the project value and user benefits.

In the beginning of the industry, keep your original intention

When the business model of blockchain applications is not yet mature, we must keep our eyes open, rationally invest in innovative projects with potential, and reject junk projects , while closely following national policies, jointly support the development of blockchain technology and the integration of life application scenarios, and jointly welcome the new era!
