Judicial application of blockchain certificate storage technolog
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. It is decentralized, tamper proof, traceable, collective maintenance, open and transparent. These features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on blockchain, which can solve the problem of
blockchain technology can protect electronic data, prevent tampering, and leave traces of data operation in the whole life cycle of electronic data generation, collection, transmission and storage, so as to provide an effective means for relevant institutions to review. Using blockchain technology to store and issue electronic evidence is the basis of the application of blockchain technology in the legal field
in the early stage, we took the lead in the instry to set up a blockchain team, invested in the research of cryptography, distributed ledger storage structure, consensus mechanism and other core underlying technologies of blockchain, and explored the application scenarios of blockchain technology in the legal science and technology instry. At present, we mainly apply blockchain technology in the field of electronic data distributed deposit, including contract deposit, e-mail deposit, e-mail deposit, e-mail deposit, etc Document storage, structured data storage, etc
in the future, we will also make use of blockchain technology to better serve the already mature electronic contract business and the rapidly developing network arbitration business, and try more blockchain for legal science and technology, so as to promote the application of blockchain technology in the field of judicial or legal services on the premise of protecting the security and confidentiality of all parties' systems
since 2018, with the establishment of the Internet court and the development of electronic evidence platform institutions following the development of blockchain technology, and with the development and improvement of alliance chain technology, some innovative electronic evidence platform enterprises have taken the lead in applying blockchain technology to the field of electronic evidence, such as blockchain electronic evidence platforms such as easy security
easy preservation has been included in the "typical cases of blockchain electronic evidence platform" by the supreme law research group, which indicates that the blockchain technology and access evidence of easy preservation are widely recognized by the judiciary. Before that, easy security has been included in the "typical cases of blockchain intellectual property rights" by the Inner Mongolia high court and Wuxi intermediate people's court, selected in the "typical cases of blockchain platform" by the law experts' lecture hall, and selected in the "2020 China blockchain enterprise investment map" by the China business intelligence network, and its actual qualification has been recognized
blockchain electronic evidence is by no means a simple legal logic and theoretical framework of "using blockchain technology is blockchain electronic evidence". Only by using blockchain technology to ensure the authenticity, legitimacy and relevance of electronic evidence before, ring and after the chain, can we ensure the conversion of ordinary electronic data into judicial credible blockchain electronic evidence
at the technical level, blockchain, CA, time stamp, encryption algorithm and other technologies are used to authenticate the real name of platform users, and block chain store the user's signed data, so as to form a full evidence chain recording the key details of the whole process, and generate tamperable hash encrypted files, so as to ensure the authenticity and reliability of the data before being chained and the integrity of the data when being chained
after being linked, easy security stores relevant data synchronously on the servers of notary office, Arbitration Commission, Internet court, right protection center, judicial appraisal institute and other institutions through the open platform of security chain; It can also conct visual blockchain inspection on the official websites of notary office, Arbitration Commission, judicial appraisal institute, Capital Intellectual Property Association, etc. Ensure that the whole process can be traced, the whole data can be verified, and the whole link can be trusted.
In Internet cases, electronic evidence has become a difficult problem in Internet trials because it is difficult to store evidence, collect evidence and notarize. By using blockchain technology, easyprovision can solve the whole link trustworthiness problems of electronic evidence, such as generation, storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the data's trustworthiness and security; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection
easy preservation since 2014, we have been deeply engaged in the R & D and application innovation of the underlying technology of blockchain . By expanding the judicial service channels, we have successfully taken the notary office, judicial authentication center, Internet court, Arbitration Commission, right protection center and other authoritative institutions as the important nodes of the preservation chain, so that electronic data can be saved from the aspects of generation, certificate storage, right protection To the final use, the relevant judicial institutions do synchronous supervision and notarization to enhance the credibility of the blockchain certificate data
1. Financial services
the application of blockchain in the financial field has already spread out, which is not a new thing. The application of blockchain in financial technology has been widely concerned and highly valued all over the world
in mainland China, China UnionPay signed a strategic cooperation agreement on mobile payment with Bank of China in early 2018, explored cooperation in the field of blockchain, and then cooperated with Jingdong to jointly launch the "Internet financial payment security alliance risk information sharing (distributed query) platform" based on blockchain
in Hong Kong, China, the Hong Kong Monetary regulatory authority is one of the earliest regulators to launch sandbox, supporting financial innovation experiments including blockchain technology; The HKMA has also joined hands with the banking instry to launch etradeconnect, which is the first large-scale trade financing information sharing platform for Hong Kong banking instry to apply blockchain technology< On September 18, 2018, Hangzhou Internet court officially launched the chain and became the first court in the world to use blockchain for trial
it is understood that prosecutors can submit electronic evidence such as contract, rights protection process and service process details online through online complaint portal, and notarization office, forensic identification center, CA / RA organization, court and other chain nodes can witness and endorse together to provide one-stop service for prosecutors. Hangzhou Internet court of Zhejiang Province made a public judgment on a case of infringement on the right of network dissemination of works' information, and confirmed the legal effect of electronic data with blockchain technology for the first time
3. Intellectual property
blockchain and related distributed ledger technology provide the possibility for the protection and registration of intellectual property, as well as evidence in the registration stage or court litigation stage. These technologies can also speed up the above intellectual property protection and registration process in a cost-effective way
4. Logistics
in early 2018, rookie and tmall global jointly announced that blockchain technology has been used to track, upload and verify the logistics full link information of cross-border imported goods
after all nodes of the logistics chain are connected to the blockchain, the goods can be traced from manufacturers to consumers, forming a complete chain; The more links the commodity is missing, the more likely it is to be a fake proct
5. Electronic invoice
on August 10, 2018, Shenzhen International Trade revolving restaurant issued the first electronic invoice of blockchain in China. It is understood that this electronic invoice of blockchain was led by Shenzhen Taxation Bureau and provided by Tencent with underlying technology and capability
different from traditional e-invoice and simple e-invoice on the chain, this blockchain e-invoice integrates "capital flow and invoice flow", combines invoice issuing with online payment, and opens up the whole process of invoice application, invoice issuing, reimbursement and tax declaration
in addition to the above fields, the application of blockchain has broad blue ocean prospects. In the future, new technology application and development will emerge in all walks of life, and blockchain will flourish.

there are still many practical applications of blockchain. You can learn more about relevant information
there are many applications of blockchain technology, such as blockchain traceability, blockchain electronic invoice, blockchain judicial deposit, blockchain loan and so on. Now the blockchain technology is developing rapidly, which is far beyond our imagination. Detailed applications can be understood in cryptography finance.
- original title: market analysis of China's blockchain instry in 2019: enabling various instries to accelerate the application landing, there will be two opportunities for future applications
2019 - blockchain "mainstream application year"
since August 2018, the electronic invoice of blockchain was issued for the first time in Shenzhen. So far, it has issued more than 6 million electronic invoices, with an amount of 4 billion yuan, and has access to more than 5300 enterprises, Covering more than 110 detailed instries. In addition to the field of electronic invoice, blockchain has also been successfully implemented in many project scenarios, such as supply chain finance, legal deposit, cross-border payment, etc.
at the recent "thousands of people watching fire" conference of blockchain instry, the reporter of economic daily learned that in 2019, the technology implementation and application has brought blockchain into the "mainstream application year". On the one hand, many Internet giants have a solid technical foundation, on the other hand, they actively explore more valuable scenarios to find development opportunities in the enabling real economy
"blockchain technology can play the role of anchoring, sharing and increasing trust in the whole social information flow, making the chaotic information credible. Compared with the past, this is a" qualitative leap. " Zhang Kaixiang, chief architect of Weizhong bank's blockchain, said, "risk control and business rules design based on trusted data can improve efficiency, rece risks and rece operating costs." He pointed out that as a connector, it is not meaningful for a single enterprise to operate the blockchain, and it is more meaningful to share it as an open source solution to realize the ecological co construction of the instry
"we have been exploring and practicing open source, starting from the underlying technology platform and combining with the scenes of finance, instry, Internet of things, culture and entertainment, to jointly build an open, transparent and efficient technology and instrial community. Open source ecology helps to activate the creativity of the instry. We will continue to start from the open source community and improve a complete set of systems such as system construction and skills training, so as to benefit more people. "
in 2019, the market scale of China's blockchain instry will exceed 100 million yuan
China's blockchain instry is still in its infancy, but with the continuous support of national policies, the continuous progress of instry technology and the increasing demand of downstream application fields, China's blockchain instry is expected to continue to maintain high-speed growth. According to the statistical data of in depth analysis report on business model innovation and investment opportunities of China's blockchain instry published by foresight Instry Research Institute, the market scale of China's blockchain instry was less than 6 million yuan in 2011, and the market scale of China's blockchain instry increased by 32 million yuan by 2017, By 2018, the market scale of China's blockchain instry has reached 67 million yuan, always maintaining a rapid growth rate of more than 80%. It is predicted that the market scale of China's blockchain instry will exceed 100 million yuan in 2019, and that in 2022, driven by policy support and downstream demand, the market scale of China's blockchain instry is expected to exceed 450 million yuan
market size statistics and growth forecast of China's blockchain instry from 2015 to 2022
data source: the audited enterprise asset confirmation, registration and circulation records, etc., sorted out by foresight Instry Research Institute, are stored on the platform in the form of traceability. Based on this, banks can carry out fast financing and loan business, save the cost of guarantee and other links, greatly improve the efficiency, and make the risk of financing and loan controllable as a whole
electronic data storage is an important application field of blockchain technology.
the provisions of the Supreme People's Court on Several Issues concerning the trial of cases by Internet courts, which came into effect in September 2018, clearly states that electronic data storage can be solved by blockchain and other technical means. Xiang Dan, vice president of bibox digital asset trading platform, said that electronic data deposit is an important application field of blockchain technology“ Blockchain technology has the characteristics of preventing tampering, leaving traces in the event, post audit and security protection, which is concive to improving the credibility and authenticity of electronic evidence. The combination of blockchain and electronic data storage can rece the cost of electronic data storage, improve judicial efficiency and enable judicial business. For example, the contract management based on blockchain has been applied in many Internet courts. "
according to Zhou Jianrui, co founder of coinword, a trusted content community, the application of electronic data storage based on blockchain can also help deepen the reform of "release management and service" and improve administrative efficiency. In Beijing Haidian District and other pilot areas, blockchain technology is playing the role of efficient data sharing, secure transmission and credit support. When applied in the field of government affairs, it can realize real-time data sharing of various departments and effectively assist window personnel and examination and approval personnel to quickly verify the authenticity of materials. For example, the public security, civil affairs, housing management and other departments "on the chain", in dealing with real estate transactions can be fast and accurate, "one key" verification of multi-party information, greatly saving social costs
there will be two opportunities for the application of blockchain
because the social recognition of blockchain is not high, the people who understand and use blockchain are still very limited, and the penetration of blockchain into the real economy still needs a graal process. " Yuan Yuming, CEO of fire coin China, introced that they used the open, transparent and tamper proof characteristics of blockchain to explore a new path of art traceability and anti-counterfeiting by means of high-precision full pixel scanning and archiving; By constructing the trust mechanism in the multi-party cooperation scenario, the integral information platform for multi-party participation and resource sharing is developed“ Next, there will be two opportunities for blockchain application:
one is training. With the entry of enterprise giants one after another and the continuous penetration of the real instry, more people will learn about blockchain through training, which will become a new market demand
the second is to provide consulting and technical solutions to more traditional enterprises to help them penetrate the blockchain into more traditional fields and promote the consumption rection, efficiency enhancement, transformation and upgrading of the real instry. "
Using blockchain technology to store and issue electronic evidence is the basis of the application of blockchain technology in the legal field
in the whole life cycle of electronic data generation, collection, transmission and storage, blockchain technology can protect electronic data, prevent tampering, and leave traces of data operation
using blockchain technology to preserve electronic evidence, the electronic data that needs to be deposited is recorded in the form of transaction, stamped with time stamp, and recorded in the block, so as to complete the process of data preservation and deposit. In the process of data storage, multiple participant nodes witness together and maintain a distributed ledger, which greatly reces the possibility of data loss, tampering and attack
the combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate electronic data collection and evidence identification, and improve litigation efficiency
As an E-contract platform that focused on blockchain technology as early as 2015, we have taken the lead in the instry to set up a blockchain team in the early stage, invested in the research of cryptography, distributed ledger storage structure, consensus mechanism and other core underlying technologies of blockchain, explored the application scenarios of blockchain technology in the legal science and technology instry, and cooperated with a number of domestic authoritative judicial appraisal institutions and The notary office has set up a certificate storage alliance chain. At present, the legal department mainly applies blockchain technology to the field of electronic data distributed certificate storage, including contract certificate storage, e-mail certificate storage, document certificate storage, structured data certificate storage, etc
at present, financial management is mainly carried out by information system, including LIS system, PACS system and OA system in addition to his system [5]. At present, except for the hospitals with advanced technology in some developed areas, most hospitals have not yet achieved a high degree of integration between the systems. Therefore, the differences in basic operation algorithms, data collection and feedback methods lead to the poor timeliness of information disclosure of each mole of the financial system, which can not meet the requirements of government departments for financial transparency. With the support of blockchain technology, the hospital's various mole systems can operate in an integrated way, and the system data of different sectors can be extracted and shared in time, which lays a solid foundation for the integration of hospital's financial system accounting, budget implementation, capital revenue and expenditure, financial analysis, etc
2. Deepen the content of financial management
with the continuous deepening of medical reform, the business volume of medical institutions has increased, and the more refined the financial management is required. However, the current hospital financial management is far from enough segmentation. Under the diversified changes of medical insurance and expenditure, the lag of information statistics seriously hinders the accurate and automatic operation of the financial system. Strictly speaking, hospital financial management only includes budget management, cost management and other contents, and subsequent other expenses are easy to be connected in the calculation process, which can not meet the needs of financial function integration process. Therefore, we should sort out the existing financial work, take the financial budget, revenue and expenditure as the source of management, and bring the medical project research funds, operating funds, expenditure approval into the scope of financial management. The introction of blockchain technology into the hospital financial management system can not only realize the above financial management steps, but also investigate and track the use of funds in real time, so as to realize the traceability of the source and the clarity of the direction of funds in the process of investigation. In this way, the horizontal development of financial content can fully improve the efficiency of hospital financial management
3. Improve the efficiency and accuracy of hospital financial management
hospital financial management plays an important role in the daily operation of the hospital, and also determines the accuracy of hospital financial information. The hospital should focus on improving the financial management to prevent and control the economic crisis caused by the financial management failure. In terms of the current enterprise financial management, the application of blockchain technology and AI intelligence is the overall development trend. Therefore, the combination of blockchain technology is an important grasp to upgrade the hospital financial management system. Affected by the characteristics of the hospital instry and the limitations of technical means, in the past, the financial management was mainly based on post inspection accounting, and the financial changes were involved early and the control was relatively lacking. In the face of increasingly detailed cross department financial data, the traditional financial management audit mode needs a lot of manpower in the aspects of evidence query, audit judgment and financial budget. The distributed bookkeeping technology and weak centralization of blockchain technology make it automatic and efficient to record financial transaction data after the verification of blockchain network nodes There are complete and remarkable characteristics in time and space. The hospital financial system built by blockchain technology can collect all kinds of effective financial data in real time and conct dynamic analysis according to the smart contract, which greatly improves the efficiency and precision of hospital financial management_ To ensure the safety of financial management in all departments of the hospital
4. Strengthen financial budget management
traditional hospital financial management is usually based on the past frequency of equipment use and the range of drug use. Some hospital financial managers think that it is only necessary to allocate resources according to the requirements of higher authorities, which leads to the intelligent financial system can not be well implemented in the hospital financial budget management system. The smart contract part in the blockchain technology can effectively enhance the control of hospital funds. The so-called smart contract is a program that automatically processes assets based on blockchain technology according to preset conditions. Blockchain technology is characterized by significant independence from the participation of third parties, so it is only necessary to input the funds allocated to the budget into the blockchain from the source, and the traceability and whereabouts of the budget funds can be presented clearly and transparently [7]. Smart contract mechanism can ensure the reasonable use of budget funds, and obviously eliminate the illegal use. In addition, blockchain technology can monitor the budget execution in real time and give early warning to the budget data changes with different usage. With the help of the self settlement (clearing) function in the smart contract, the transaction settlement (clearing) can be automated and fast, which can significantly rece the error rate of financial personnel and improve the budget implementation effect
