Blockchain e-Cert

1. In 2020, with the promotion of online litigation mechanism and the promotion of the application of blockchain electronic evidence by Internet courts, the number of cases involving blockchain electronic evidence will increase significantly. First line Internet companies and leading enterprises in various instries generally use blockchain electronic evidence service in daily legal work because of their sensitivity to new technologies. The Supreme People's court has set up 14 major topics, among which the research group of "Research on electronic litigation rules in the Internet Era" focuses on "basic principles of electronic litigation; The conditions, scope and methods of online case filing, online court hearing and electronic service; In order to provide suggestions for the supreme legal system to formulate judicial policy and issue judicial interpretation, we should study and form a complete and systematic draft of electronic litigation rules
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.

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

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, explored the application scenarios of blockchain technology in the legal science and technology instry, and built a certificate storage alliance chain in parallel with a number of domestic authoritative forensic authentication institutions and notary offices, At present, blockchain technology is mainly used in the field of electronic data distributed storage, including contract storage, e-mail storage, file storage, structured data storage, etc

in the future, we will also make use of blockchain technology to better serve our already mature electronic contract business and the rapidly developing network arbitration business, and make more attempts to blockchain for legal science and technology, so as to promote the application of blockchain technology in the field of judicial or legal services while protecting the security and confidentiality of all parties' systems

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

Taking the micro right of the blockchain intellectual property protection platform of e-baoquan as an example, its forensics technology has the invention patent certificate issued by the State Intellectual Property Office. When users collect evidence through the Internet, they will automatically obtain the current standard time, and calculate the hash digest value of the forensics file according to the standard time, Then the hash summary value and forensics file are uploaded to the Security Center for blockchain preservation, which makes the evidence chain more complete

at the same time, different from other ways of evidence collection, micro right and notary office jointly develop "forensics guarantee v2.0", and have relevant soft work certificates, which ensure that the whole process of evidence collection is carried out under the supervision and operation of notary office, and ensure the cleanness of forensics environment and objectivity of evidence collection. Forensic methods include: Web forensics, screenshot forensics, screen recording forensics and video forensics. Users can choose the forensics methods according to their needs, and complete the forensics in a few seconds at the fastest. They can also apply for the issuance of notarial certificate and notarial custody letter online
