Blockchain distributed certificate storage technology
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
however, in view of the characteristics of electronic data, such as reprocible, easy to tamper, difficult to confirm, difficult to provide evidence and so on, electronic evidence urgently needs a professional, reliable and judicial credible technology to effectively solve the trust problem of electronic evidence
blockchain has the advantages of decentralization, distributed accounting, encryption and traceability, which can ensure the integrity and authenticity of data on the chain. Once it is tampered or forged, it can be found. At the same time, because the blockchain has the characteristics of Distributed Accounting, even if the data on indivial nodes are deleted, other nodes can still save the data completely, ensuring the normal operation of the whole blockchain storage system
in 2018, the supreme law of the people's Republic of China clearly pointed out in the provisions on Several Issues concerning the trial of cases by Internet courts that the electronic data submitted by the parties can be verified by electronic signature, trusted time stamp, hash value verification, blockchain and other technical means of evidence collection, fixation and tamper proof, or by electronic forensics storage platform authentication, The Internet court should confirm. This is the first time that the legal effect of blockchain technology in electronic data is affirmed from the judicial level
based on the above advantages, blockchain is naturally suitable for electronic data storage. The introction of blockchain can effectively solve the authenticity and legitimacy of electronic evidence and make the process of electronic data storage more reliable. By using blockchain technology, easyprotection can solve the whole link trustworthiness problems of electronic data, such as generation, certificate storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the credibility and security of the data; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection.
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.
In order to meet the growing demand for litigation services of the people in the process of regional collaborative development between Sichuan and Chongqing, our blockchain certificate keeping technology will play a series of roles such as certificate keeping, authentication and evidence collection in cross domain case filing, petition joint control, online litigation, joint conference and other cooperation between Sichuan and Chongqing, making long-distance and contactless cooperation more standardized, convenient and efficient. To provide assistance for Sichuan Chongqing high court to achieve inclusive, equal, convenient, efficient, intelligent and accurate litigation services
this paper briefly introces the application of blockchain evidence storage -- "real hammer" trusted electronic evidence platform
Real hammer "trusted electronic evidence platform, through cooperation with forensic authentication institutions, notary offices, arbitration institutions, Internet courts, etc., realizes the storage, retrieval and issuance of evidence on the chain, and reces the cost of electronic data evidence preservation, It is convenient for electronic data collection and evidence identification, and improves the litigation efficiency in the field of judicial evidence preservation
at present, the evidence traceability mode of "real hammer" trusted electronic evidence platform has been recognized by many courts in Beijing, Xiamen, Guangzhou and Shenzhen, and some banks and state-owned enterprises have begun to use "real hammer" trusted electronic evidence platform
Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
it is an important feature of electronic contract system, which can not be tampered with and forged, and effectively improve the security of electronic contract
in 2016, we, together with Microsoft (China) and onchain, jointly launched the establishment of "French chain", which deeply integrates electronic contract and blockchain technology. Digital fingerprint information such as signing time, signing subject and file hash value of electronic contract will be broadcast to the respective nodes of all members of "French chain". Once all the information is stored, no party can tamper with it, so as to realize the anti tampering of electronic evidence and ensure its objective authenticity
We mainly apply blockchain technology to the field of electronic data distributed storage, including contract storage, e-mail storage, file storage, structured data storage, etc
the specific forms of electronic evidence in judicial practice are becoming more and more diversified, and the frequency and amount of electronic data are increasing significantly. Different types of electronic evidence have different forms of formation, but they are easy to die out, easy to tamper with, and highly dependent on technology. Compared with traditional physical evidence, it is more difficult to determine the authenticity, legitimacy, and relevance of electronic evidence through judicial review
in the whole life cycle of the generation, collection, transmission and storage of electronic data, blockchain technology can be used to protect electronic data, prevent tampering, and leave traces of data operation, so as to provide effective means for relevant institutions to review. Using blockchain technology to preserve electronic evidence, the electronic data that needs to be preserved 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 preservation. 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 the litigation efficiency in the field of judicial storage
The unique characteristics of blockchain technology, such as non tampering, non repudiation and multi-party participation, are naturally consistent with the requirements of electronic data storage. Electronic data storage is an important application field of potential blockchain technology
in the face of the growing demand for electronic data, the traditional way of certificate keeping graally shows some shortcomings, such as high cost, low efficiency and difficulty in obtaining information. In addition, in judicial practice, the parties generally lack the ability to adce evidence, the quality of electronic evidence submitted to the court is poor, there are a large number of improper evidence collection proceres, incomplete evidence, poor directivity to the facts of the case and other problems, which directly affect the proportion of electronic evidence in litigation
the combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate the evidence identification of electronic data, and improve the litigation efficiency in the field of judicial storage
therefore, we have been committed to integrating blockchain technology into procts to provide users with financial level security: for example, through the joint establishment of a judicial deposit chain with multiple parties (including forensic identification center), we can realize the permanent solidification and preservation of decentralized evidence, and simplify the process of traditional evidence collection and issuance. That is to use the distributed blockchain storage technology to ensure that the contract evidence is not tampered
