1. What is the development trend of blockchain?

Since 2018, the blockchain industry has been booming. Blockchain-related exploration and application are no longer limited to the underlying platform. Internet giants and financial giants have strengthened the use of blockchain in the fields of finance, public welfare, commodity traceability, etc., especially in the financial field, with blockchain technology as the core. Applications are being implemented faster.
The blockchain industry is in a stage of rapid development
my country’s blockchain industry is currently in a stage of rapid development. According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, as of the end of March 2018, the number of blockchain companies in my country with blockchain business as their main business reached 456 From upstream hardware manufacturing, platform services, and security services, to downstream industrial technology application services, to industry investment and financing, media, and talent services to ensure industrial development, companies in various fields are basically complete.
Judging from the application scenario classification of the TOP20 companies on the ranking list, in addition to 13 companies focusing on blockchain infrastructure and platform construction such as underlying platforms and blockchain hardware, the application scenarios of blockchain have gradually become richer. . Judging from the distribution of industry subdivisions, there are 7 industry application companies, mainly Internet companies (Alibaba, JD.com, Tencent) applied to public welfare and product traceability, as well as innovations in the evolution of financial companies (Ping An, China Merchants Bank, Bank of China) Fintech applications such as supply chain finance, bill and transaction clearing.
Since blockchain can make information non-tamperable and eliminate the possibility of data falsification from the root, the financial industry, especially those with higher requirements for real data, will embrace blockchain more actively.
Analysis of blockchain development trends

Technological innovations such as blockchain are of great significance to the financial industry and are expected to accelerate the process of "credible digitalization" and continue to drive finance "from virtuality to reality."

2. What are the service applications that use blockchain technology?

Blockchain technology has a distributed ledger that cannot be tampered with, ensuring the transparency and sharing of information, thereby making business activities between midpointsThe cost of building trust and reaching consensus has dropped significantly. This article provides an in-depth interpretation of four typical business scenarios: supply chain finance, commodity traceability, technology and medical care, and industrial Internet.
1. Blockchain adds supply chain finance. Today, the supply chain of most commodities, from the provision of raw materials to the manufacturing of finished products, involves several upstream and downstream small and medium-sized enterprises; and these enterprises are faced with the challenge of unlocking supply chain working capital. pressure. Supply chain finance refers to banks and other financial institutions making systematic financing arrangements for all member companies of the supply chain, thereby forming a win-win situation for core buyer companies and suppliers: the buyer optimizes working capital, and the supplier generates additional operating cash flow, thus Minimize risk throughout the supply chain. There are three pain points in traditional supply chain finance: 1. Information cannot be shared, efficiency is low, and credibility is poor; 2. Bill circulation is inconvenient, contract settlement is slow, and there are often financial risks; 3. Credit cannot be transferred and financing is difficult. The blockchain can realize the following functions: 1. Sharing transaction data, receivables and payables data among core enterprises, multi-level suppliers, and financial institutions while protecting commercial privacy; 2. Transfer of corporate claims and automatic settlement of funds, accelerating corporate recovery. Payment and repayment; 3. The core enterprise's payment commitments flow among multi-level suppliers and financial institutions to convey the core enterprise's credit.
2. Blockchain traceability In the field of commodity traceability, blockchain and Internet of Things technology are combined to trace the entire process of commodity circulation to prevent unscrupulous traders from taking advantage of the information asymmetry in the commodity chain to produce counterfeit and inferior commodities. Shoddy goods. This prevents certain participants from tampering with data or falsely claiming that information is lost when circumstances are detrimental to them, making it difficult to provide evidence and pursue accountability. In addition, blockchain traceability can open up information islands in different links of the supply chain and improve the collaboration efficiency of the supply chain.
3. Blockchain helps medical services Blockchain technology can open up multiple links such as hospital prescription issuance, pharmacist review, drug distribution, drug payment, and process supervision. Through blockchain distributed storage and accurate matching of information on the chain with patients, the one-time dispensing effectiveness of prescriptions is ensured, prescription modification or abuse is prevented, and supervision is facilitated. In the future, patient information, prescription information, drug circulation information, etc. will be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios.
4. Integration of Blockchain and IoT Industrial Internet At the 5th World Internet Conference, the supET Industrial Internet platform, which integrates Internet of Things and blockchain technology, was selected as the world's leading Internet scientific and technological achievement and became the only The award-winning industrial Internet platform.

In addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content copyright services, etc. In industries such as government, finance, industry and logistics, healthcare, retail and the Internet, blocks have a wide range of business application scenarios.

3. How is blockchain used in the legal field?

Using blockchain technology to deposit and issue electronic evidence is blockchain technology.Fundamentals of application in the legal field.

Blockchain technology can be used to securely protect electronic data, prevent tampering, and conduct data processing throughout the entire life cycle of electronic data generation, collection, transmission, and storage. Traces of operation.

Use blockchain technology to preserve electronic evidence, record the electronic data that needs to be deposited in the form of transactions, stamp it with a timestamp, and record it in the block, thereby completing the process of data preservation and evidence depositing. process. During the data storage process, multiple participating nodes jointly witness and jointly maintain a distributed ledger, thus greatly reducing the possibility of data loss, tampering, and attack.

The combination of blockchain and electronic data storage can reduce the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve litigation efficiency.

4. Re-understand the blockchain: Enlightenments brought by more than 1,550 application cases

Author: Ran Wei

(This article is excerpted from "2021 Global Blockchain Application Market Report")

When we talk about blockchain, anyone who knows something about blockchain can express themselves more or less on related topics. opinion. For example: from the perspective of technical system, blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm; from the perspective of functional attributes, blockchain is decentralized, non-tamperable, and full-process. Features such as leaving traces, traceability, collective maintenance, openness and transparency.

Looking back at the history of blockchain, there is no way around Bitcoin. On January 3, 2009, the Bitcoin genesis block with serial number 0 was born. A few days later, on January 9, 2009, Bitcoin block number 1 was born. When two blocks are connected, the blockchain is "born."

The inventor of Bitcoin, whose pseudonym is “Satoshi Nakamoto”, may find it difficult to imagine: In the past 12 years, with Bitcoin as the center, a huge “cryptocurrency family” has spread all over the world. The financial market set off a "big wave" that continues to this day. During this period, innovation and risks related to cryptocurrency are intertwined, progress and bubbles coexist, and pursuit and criticism coexist, and it drives government departments of various countries to continuously improve the monetary and financial systems, social governance and supervision systems.

At the same time, the blockchain that accompanies Bitcoin is also evolving rapidly, and has long gone beyond the scope of "Bitcoin's underlying technology" and has been applied to every corner of social and economic development.

So, what mechanism does blockchain work through? What are its advantages compared to traditional technologies and models? What is its application effect? In the "2021 Global Blockchain Application Market Report" jointly released by Capital Lab and Yuanwang Think Tank, we analyzed more than 1,550 global applications in 2020 and the first quarter of 2021.Case studies attempt to provide empirical answers to the above questions. At the same time, based on the study of these cases, we can establish a new understanding of blockchain: blockchain is trust, blockchain is sharing, blockchain is transaction, blockchain is substitution, and blockchain is efficiency.

In the Bitcoin creation paper "Bitcoin: A Peer-to-Peer Electronic Currency System", "Satoshi Nakamoto" repeatedly emphasized that Bitcoin has the characteristics of not relying on a "trusted third party". That is the characteristic of “decentralization”.

On the other hand, the underlying technology of Bitcoin, the blockchain, is precisely designed for "trust." In other words, reshaping "trust" in the digital age is the most basic function of the blockchain, but this trust has been transformed from trust between people and legal entities to trust between machines and machines. Trust between blocks and between nodes. Interestingly, the subsequent “smart contract” function has further strengthened this trust through its integration with the blockchain.

Identity coding and authentication are the first steps to achieve the above-mentioned trust mechanism, and the distributed identity (Decentralized Identity, DID) system is the core of it. With DID applications, everyone from individuals to organizations to IoT devices, from physical items to virtual products, can be given digital "identities" and achieve trusted interactions. It is precisely because of this that blockchain-based certificate storage, empowerment, verification, circulation, and transactions can be realized, and only then can blockchain be implemented in various industries.

Application cases from around the world show that new trust mechanisms provide new rules and motivation for social and economic operations:

l China is comprehensively promoting blockchain electronic certificates Applications such as "one fish, one code", "one fruit, one code", "one tea, one code" and other applications are driving the global Anti-counterfeiting traceability of agricultural products and upgrading of food safety systems;

l Through the combination of blockchain, big data, and artificial intelligence, the credit "portrait" of an enterprise is more accurate and can be obtained faster and more accurately. Lower-cost financing services;

l Charitable charity organizations have put charity funds "on the chain" to form a more transparent and standardized charity tracking and management system;

l Relevant cities in China have launched a blockchain-based gas cylinder product traceability management system, and the credibility of the source of gas cylinder file information and the level of gas cylinder safety management have been greatly improved;

l Germany is developing its distributed energy resources Assets establishes a digital registration system based on identity authentication to promote the development and trading of renewable energy and cope with the arrival of the digital energy era...

Among the three types of blockchain (public chain,Among the alliance chain and private chain), the alliance chain has been the most widely used. In addition to considerations of technical performance, operational efficiency, operability, expected results, etc., this is mainly because all parties in the alliance already have a certain foundation of trust. This also shows from another perspective that in blockchain applications beyond cryptocurrencies such as Bitcoin, "multi-centralization" rather than complete "decentralization" is a more realistic option.

In addition, it is undeniable that unlike the proof-of-work mechanism that Bitcoin “mining” relies on, the blockchain cannot completely ensure the integrity of the on-chain data from the source in the actual application process. Authenticity. In other words, a certain alliance member or node may provide false data intentionally or unintentionally. However, with the help of blockchain's non-tampering, traceability, multi-party consensus and other characteristics, the alliance can identify counterfeiting behavior and impose corresponding punishments, such as "kicking" the counterfeiting members from the node. Therefore, in a sense, blockchain-based trust largely establishes alliance members’ awe for the authenticity of data and deters data fraud.

If "trust" is the foundation of blockchain applications, data sharing is the core of blockchain applications. Without data sharing, there will be no cooperation, and the practical application of blockchain will be impossible.

l The State Administration of Foreign Exchange's "Cross-border Financial Blockchain Service Platform" pilot has been fully launched, promoting foreign trade exports through information exchange between foreign exchange bureaus, taxation, banks and enterprise-related market entities. Business development;

l The "Insurance/Claims Alliance Chain" jointly established by 11 insurance companies in Taiwan has been put into operation, and each company has achieved "single application and common documents" on this platform;

l Blockchain platforms such as Contour and TradeLens are reshaping the global supply chain and providing impetus for the digital transformation of international trade through data collaboration among enterprises, financial institutions, shipping companies, terminals, customs and other institutions... .

l In China, through data collaboration, various government departments have realized "one data, one source, one source for multiple uses, one network, and full network operation";

l Through The "Judicial Chain" platform allows all types of electronic evidence to be seamlessly connected with judicial institutions such as notarization, arbitration, judicial appraisal, and courts, which improves the efficiency of the judicial system while reducing costs;

l Targeting grassroots nationwide The court's "cross-domain collaboration mechanism for trial auxiliary matters" can realize "cross-domain service and cross-domain evidence collection" between courts in different regions, effectively improving the efficiency of trial auxiliary matters and trial quality and efficiency, and reducing judicial operation costs... ….

l China's "Guangdong-Hong Kong-Macao Greater Bay Area Combination Port" project was officially launched, which can support the interconnection and interoperability of trade parties among the five major customs jurisdictions of the Greater Bay Area and become the first connected port in the Greater Bay Area , customs, logistics,An interconnected and shared blockchain network for the entire process of enterprise, finance and other trade;

l Japan's KDDI Telecom, Hitachi, Kansai Electric Power, Sekisui Construction and other large enterprises have established the blockchain alliance NEXCHAIN ​​to Form a cross-industry real estate information sharing and management model, and promote cross-industry innovation;

l The French Renault Group completed the test of its blockchain project "XCEED" for use in parts suppliers and automobiles Share compliance information among manufacturers and streamline compliance certification….

Although the above application cases in finance, government affairs and various industries are only a few typical cases, they are enough to illustrate that: on the one hand, data sharing is an inherent requirement of blockchain applications. In terms of specific implementation, everything must start from breaking "data islands" and "information asymmetry"; on the other hand, the application practice of blockchain has in turn promoted cross-level, cross-department, cross-industry, cross-region, and cross- Data sharing and unprecedented cooperation across national borders.

It can also be seen from the above cases that based on the transparency, security, trustworthiness and other characteristics of the blockchain, data sharing allows cooperation that originally seemed impossible to be achieved, and more Open innovation results; data sharing can effectively improve the operating efficiency of business systems, financial systems and social governance systems; various organizations promote their own organizational changes and process changes while sharing and cooperating with external institutions.

Based on trust and sharing, "transaction" is the most intuitive and deepest manifestation of the value of blockchain applications. Currently, blockchain is opening a new chapter in the transformation of transaction models in various industries around the world.

From the perspective of functional architecture, blockchain-based transactions are by no means just a change in the transaction process. Instead, they integrate various unique functions of the blockchain. Integrated integration of blockchain applications such as logistics, payment/settlement, supply chain financing, insurance, and network security.

From the perspective of application form, blockchain-based transactions transcend the traditional concept of product or service transactions and represent the realization of the value of a wider range of data in circulation.

From the perspective of application scenarios, transactions based on blockchain involve the upgrading of the physical industry, the digital advancement of the financial industry, and the innovative application of the "token economy".

In the physical industry, take the application of agricultural blockchain as an example: on the one hand, supply chain traceability based on blockchain has become an important barrier to food safety; but on the other hand, for growers or For farmers, the supply chain traceability function is far from enough. How to help them expand the sales of agricultural products and obtain more income as much as possible is the "hard truth" for blockchain technology to continue to promote agricultural development. In other industries, the same applies.

Against the above background, the global real industryNew trading platforms continue to emerge:

l The Indian government uses blockchain platforms to help farmers in remote areas sell agricultural products to earn higher incomes while reducing intermediate fees;

l Swiss company Cerealia builds a blockchain-based agricultural product trading and financing platform to promote agricultural product exports in emerging market countries around the world;

l The world’s largest independent refined sugar producer, Al Khaleej Sugar in the United Arab Emirates The company launched DigitalSugar.io, a blockchain-based sugar product trading platform, to realize spot-based international raw sugar trading;

l Jiangxi Ganzhou launched a blockchain-based international timber electronic trading platform to facilitate timber trading. Carry out full-process on-chain management, and will provide full industry chain services such as regulatory cloud warehouses, logistics, finance, and insurance for the timber market;

l Shandong Province has launched the Shandong Internet Chinese Medicinal Materials Trading Platform, which will be implemented through the district Blockchain and other technologies realize online integrated services of quality control, trading, payment, settlement and supervision;

l Weitang Town, Xiangcheng District, Suzhou released a blockchain-based pearl online trading platform to Core parameters and test reports will be uploaded to the chain for certification, and functions such as supply chain management, trade finance, smart contracts, payment settlement, and incentive mechanisms will also be added;

l Honeywell launches new aircraft parts GoDirect Trade, an online trading platform for spare parts and second-hand parts, provides a valuable reference for large manufacturers on how to apply blockchain to parts trading and circulation...

In the financial industry, blockchain is promoting the digital advancement of financial transaction business in aspects such as securities trading, asset securitization, trade financing, and cross-border settlement:

l The Australian National Stock Exchange has launched ClearPay, a digital securities trading platform based on distributed ledger technology, which can provide multi-currency, real-time DVP settlement on the same day and will replace the original exchange settlement system;

l Switzerland The company Finka has launched a related securitization token investment platform based on livestock from organic pastures in Bolivia to promote the development of the local livestock industry;

l The American company Securitize has established a Japanese real estate investment platform based on digital securities , aiming to revitalize idle real estate in rural Japan and enhance the vitality of the rural economy;

l China Postal Savings Bank and China Construction Bank completed the first cross-blockchain platform forfaiting transaction, Hua Xia Bank Kunming Branch’s first Realize forfaiting resale business in the secondary market;

l Nanjing Iron and Steel completed blockchain-based iron ore transactions with Rio Tinto of Australia and Vale of Brazil respectively;

l Baosteel Co., Ltd. and Australia's Rio Tinto completed the first blockchain-based RMB cross-border settlement transaction...

Of course, while blockchain promotes the advancement of financial transaction business, dark sides such as hype, scams, money laundering, and cyber attacks related to blockchain and cryptocurrency continue to follow. How to continue to promote financial innovation while also carrying out efficient risk prevention and control and effectively cracking down on illegal crimes is an important issue that requires long-term response. From a global perspective, China has responded with clear attitudes, strict measures, and effective measures in this regard.

The transaction changes realized by the blockchain in the real industry and financial industry are only the initial stage of the blockchain changing the traditional transaction method. The "Token Economy" is the blockchain "transaction" A higher level of functionality.

Under the framework of the "token economy", from electronic certificates to skill certificates, from credit records to public welfare activity participation records, from social media tracks to carbon emission reduction actions, when various data become When an encrypted digital proof of rights is circulated and exchangeable, it is given the function of "token".

Regardless of the investment/speculation craze of "Non-Fungible Token (NFT)", we can already see many early applications of "token economy" around the world:

l The HotCity project supported by the Austrian government uses a crowdsourcing model combined with blockchain and gamification tokens to encourage residents to submit heating waste heat hotspots to meet urban heating needs more efficiently;< br />
l Ford establishes "Green Miles" for commercial and municipal fleets using hybrid vehicles to help improve urban air quality;

l Weibin District, Xinxiang City, Henan Province, in its In the blockchain industrial park project, tokens are issued based on the points system for merchants and enterprises to establish a new commercial service platform;

l Chengdu released a blockchain-based community governance product "Chain Community", Residents can earn "time bank" points on the platform through volunteer services and other activities, and exchange them for benefits and discounts provided by community merchants;

l Global non-profit organization "Mobile Open Blockchain Plan" The Electric Vehicle Charging Network Working Group (EVGI) launches a global standard system for decentralized vehicle charging technology, covering the Tokenized Carbon Credit (TCC) scenario;

l Blockchain reward platform MiL. k cooperates with a Korean retailer to provide blockchain-based points management services to its members. Members can convert existing points into local MLK tokens through the MiL.k platform, or exchange them into other third-party points...

From the aboveCases and more can be seen that the "token economy" has several distinctive features:

The "token economy" gives asset attributes and tradable attributes to a wider range of data, and through cross-domain , cross-platform mutual trust and circulation can improve the operating efficiency of the entire social and economic system;

"Token economy" is a new value creation and realization process, which does not necessarily directly use currency as a transaction media, but more embodied in the exchange, mutual benefit and reconfiguration of various elements and resources;

"Token economy" is often combined with incentive mechanisms, through the exchange of "good people and good deeds", " The incentives of "good enterprises" and "good institutions" will effectively reshape the social value system and social credit system.

Generally speaking, the "token economy" will spawn new production factors, reshape production relations, and greatly liberate social productivity; the "token economy" represents the direction of the "information Internet" The evolution of the "Internet of Value" indicates the most exciting future of the digital economy; the "token economy" based on the blockchain has begun to take shape and has begun to bring changes to economic operations, social governance, and everyone's lifestyle. Continuously visible change. All types of institutions and individuals should be mentally and physically prepared for this change.

Like other new technologies, in the process of application and popularization, blockchain continues to produce substitution effects in terms of platforms, media, models, methods, etc.: physical documents are replaced by electronic documents, and credit records are replaced by electronic documents. Tokens are replaced, manual review is replaced by data verification, and the city management platform is replaced by the "city brain"...

Such substitutions have become the norm:

l Argentina’s central bank has begun a proof-of-concept for a new blockchain clearing system, which may replace the existing clearing system;< br />
l Korea Minting and Security Printing Corporation (KOMSCO) expanded its blockchain digital gift certificate business to replace paper gift certificates and achieved record revenue despite a sharp decline in the issuance of banknotes and coins. Improvement;

l Courts across China have begun to use blockchain electronic seals to replace traditional paper seals in the enforcement of real estate seizures;

l The Shanghai court system is using artificial intelligence , the adoption of new technologies such as blockchain, and explore the use of digital court trial records to replace manual court trial transcripts;

l The Japanese company SUSMED launched a "Clinical Data Monitoring System Demonstration Using Blockchain Technology" pilot, indicating that the drug Or the necessary monitoring process in clinical trials of medical equipment can be replaced by a blockchain system;

l Alipay and Wukong Car Rental have cooperated to launch a "face-swiping" car rental service, which uses blockchain technology and credit-free security mode, tourists only need to “swipe their faces”You can rent a car and return it through mobile phone operations;

l Under the new crown epidemic, local governments in China have intensively launched "no face-to-face, no contact, zero errands" government affairs combined with blockchain technology The service has replaced the traditional offline service method, providing a strong guarantee for the smooth progress of remote bidding, "cloud" customs clearance, financial support, resumption of work and production, etc. during the epidemic...

In addition, we can also see that through the use of blockchain technology, various enterprise-level services are also realizing substitution and evolution: from paper contracts to electronic contracts, to program-based, Blockchain contracts that can automatically execute smart contracts. Blockchain is pushing contract signing into the era of "chain signing"; from offline human resources companies to online human resources platforms to the blockchain-based human resources market , global human resources services have experienced continuous changes from the 1.0 era to the 2.0 era, and then to the 3.0 era.

Generally speaking, when the blockchain "invades" various industries, it will "mercilessly" delete all unnecessary links and processes, all unnecessary manual operations, and accelerate the The era of paperless, unmanned and automated is coming.

In the process of our analysis of more than 1,550 blockchain application cases around the world, words like "improve", "accelerate", "shorten", "lower", "reduce", "save", " Words such as "save" appear frequently in front of our eyes. These words show that the improvement of efficiency is the common pursuit of all parties involved in blockchain applications and is also the most direct result of the substitution effect of blockchain.

Numerous application practices are contributing to this:

l Kenyan company Shamba Records provides blockchain traceability, transaction and financing services to farmers in the country, currently covering more than 6,000 Small farmers and helped them increase their income by at least 40%;

l TradeWaltz, a blockchain trading platform invested by NTT DATA, Mitsubishi and other companies, completed a trial run, and the results showed that the platform can reduce traditional 50% of the workload of the trade process;

l Walmart Canada has significantly reduced invoice disputes with carriers by 97% through the application of the DL Freight blockchain platform;

l The State Grid Corporation of China’s power transaction certificate traceability inquiry platform has been put into operation, automating the entire authenticity review process for registered users and saving 99% of trusted manual review time;

l COSCO Shipping Lines and Shandong Port Group Qingdao Port have cooperated to launch a blockchain paperless import and delivery model, which can save customers nearly 24 hours on average per container;

l Taizhou, Zhejiang uses "materials" Internet + Blockchain” backThe recycling system solves the problem of marine pollution control. Compared with traditional treatment methods, this recycling system can save 94% of labor costs and 84% of operating costs...

In summary, through the joint action of trust mechanism, sharing mechanism and transaction mechanism, blockchain has formed an obvious substitution effect, improved the operational efficiency of finance, government affairs and various industries, and will Continue to create systemic change. This change is reshaping the relationship between people and machines, people and society, and people and the environment, and clearly points to three ultimate goals: efficiency, well-being, and environmental protection.

5. How to make good use of the judicial blockchain and eliminate "official copying"

Starting from 2020, blockchain technology is gradually moving from concept to implementation, with many application scenarios blooming, and products Traceability, supply chain finance, electronic certificates, copyright protection, etc. are all popular aspects of blockchain applications. In 2021, industries related to credit reporting, digital assets, data tracing and other aspects will accelerate the use of blockchain technology and benefit from it.
The work report of the Supreme People's Court proposes to open the judicial blockchain platform to support online copyright holders in uploading works, preserving evidence, and preventing and punishing online plagiarism. Data stored in blockchain technology cannot be tampered with, and is particularly suitable for online copyright protection. Make good use of the judicial blockchain as a tool to expose the "official plagiarism", which will effectively solve the difficulties of preventing and controlling online plagiarism and help create a creative environment that respects originality and advocates innovation.
Since 2018, with the establishment of Internet courts and electronic evidence platform institutions closely following the development of blockchain technology, and with the development and improvement of alliance chain technology, some innovative electronic evidence platform companies have taken the lead in applying blockchain technology. To the field of electronic evidence
The Yibaoquan blockchain electronic evidence platform uses blockchain technology to ensure the authenticity, legality and relevance of electronic evidence before, during and after it is uploaded to the chain. At the technical level, technologies such as blockchain, CA, timestamps, and encryption algorithms are used to authenticate platform users in real-name ways, and to certify user-signed data on the blockchain, thus forming a full evidence chain that records key details of the entire process and generates The HASH encrypted file cannot be tampered with to ensure the authenticity and reliability of the data before uploading to the chain and the integrity during uploading without being tampered with.

6. The main image of an online store has been stolen. How to prevent the image from being used?

E-commerce has always been the hardest hit area for intellectual property infringement. For original merchants, only by protecting intellectual property rights in advance can they take the initiative in rights protection. The first step in protecting intellectual property rights is to determine the ownership of the work and then apply for a copyright certificate.

Protecting the value of works is our original intention, and protecting every work is our mission. Microcopyright is a blockchain intellectual property protection platform under Yibaoquan. Through "blockchain + judicial + intellectual property", it provides users with services such as work rights confirmation, infringement monitoring, infringement analysis, infringement evidence collection, and agency rights protection. At present, Micro Copyright has signed contracts with many leading companies in the photography industry, relying on judicial blockchain, pre-notarization, digital copyright, and infringement data analysis.As well as strong judicial implementation capabilities, it helps companies successfully safeguard their rights in major provinces and cities across the country.

7. Can blockchain technology be applied in the judicial field?

On October 13, the Supreme People’s Court answered a question at a press conference on the “Effectiveness of the People’s Court’s Smart Court Construction Work” Mentioned: At present, there are more than 2.6 billion certificates stored on the People's Court blockchain platform, and application scenarios such as electronic evidence, electronic delivery storage verification, and tamper-proofing have been implemented. At the same time, the Supreme People's Court focuses on promoting the breakthrough application of key technologies such as judicial blockchain evidence verification, smart contracts, and cross-chain collaboration, and using blockchain technology to improve judicial credibility and efficiency!
Yibaoquan uses the technical characteristics of blockchain such as "decentralization, distributed storage, effective anti-tampering, full traceability, and traceability" to create a judicial blockchain evidence storage system to help notaries, arbitration committees, The Forensic Laboratory realizes the storage and solidification of the entire chain of electronic evidence, making the evidence verifiable, the process traceable, and the results credible. It improves the efficiency of judicial services, reduces judicial costs, and helps judicial services develop towards intelligence.
Zhongzhengbao, a brand of Yibaoquan, can build a one-stop Internet notarization system for notary offices. It uses the underlying technology of blockchain to solidify the key data uploaded by users in the notary office system and put it on the chain as evidence, which can be checked online in real time. , avoid disputes arising from the process of data uploading and storage, improve the legal quality and efficiency of notarization business data storage, and apply for online notarization services such as intellectual property rights and electronic contracts, and issue notarization certificates and notarization custody letters online. Effectively reduce the cost of notarization electronic data storage, facilitate the identification of electronic data evidence, and improve the litigation efficiency of notarization blockchain storage.
E-Baoquan can help forensic laboratories to be included in the Alliance Blockchain "Preservation Chain Open Platform" and become one of the member nodes, using the blockchain to be "decentralized, non-tamperable, full-process traceable, traceable", etc. Features: Put case information, case handling step information, appraisal opinion information and other data information on the chain, provide technical support for evidence preservation, enhance the accuracy, authenticity and traceability of forensic appraisal data, and at the same time, Realize the confirmation and preservation of digital assets, issue judicial appraisal custody letters online, conduct notarization and appraisal of blockchain data online, and improve the credibility of electronic evidence.

8. [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 greatly reduces the cost of offline evidence storage and collection, and improves the judgment process.The efficiency enables many cases that were previously unworthy of prosecution due to the high cost of rights protection to be better protected through the blockchain; the judicial chain solves the problem of low judicial service efficiency, realizes the integration and sharing of judicial data, and breaks down data islands; The judicial chain promotes the construction of the social credit system, reduces judicial costs, uses technology as the 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 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. WhenWhen parties 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 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, titled “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 requirements for linking assets. solved problem. 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 there is an island of value and it 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 does the judicial chain achieve technicalWhat about one that is technically credible and institutionally credible, and the cost is not high?

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 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 directlyThe program records the entire process of operational behavior in the blockchain, such as online submission of electronic evidence such as electronic contracts, rights protection processes, service process details, etc.;

2), the second is the full-link capability layer of the blockchain , mainly provides real-name authentication, electronic signatures, timestamps, data storage and trusted services for the entire blockchain process;

3), the third is the judicial alliance layer, which uses blockchain technology to Notary offices, CA/RA institutions, judicial appraisal centers and courts are connected together in a consortium chain, with each unit becoming 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 example, in transaction disputes involving 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, the platform canIn addition to judicial applications in Taiwan, other relevant institutions (such as other people's courts, judicial appraisal institutions, notary institutions, and filing institutions with permission) can retrieve relevant evidence from the platform in accordance with procedures, and the co-construction and sharing of resource data will also 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 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 chain has its own limitations. In the future, for the establishment of trust infrastructure and mutual trust ecology,Cross-chain technology will become a very important part of it. 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 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.

Currently, the cryptographic features introduced by Ant Blockchain include zero-knowledge proof, that is, by introducing zero-knowledgeIdentification proof is used to prove the legality of the transfer amount 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%. 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 received 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.
