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

2. More and more enterprises join the team of digital transformation, how to effectively protect data security will become the core competitiveness of this era. In 2012, the newly revised "Civil Procere Law" and "Criminal Procere Law" officially included electronic data in the legal classification of evidence, the relevant laws and regulations of electronic data began to be promulgated, and electronic data began to move towards the historical stage
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.

Recently, Shenzhen Municipal Bureau of instry and information technology released the "implementation plan for innovation and development of digital economy instry in Shenzhen (2021-2023)". The plan points out that it is necessary to give key support to high-end software, artificial intelligence, blockchain instry and other key fields, explore the application demonstration of blockchain in areas such as certificates, and strive to build a national pilot zone for innovation and development of digital economy

the implementation plan for innovation and development of digital economy instry in Shenzhen includes four parts, including general requirements, key areas, key tasks and safeguard measures. In the key areas, it is divided into 12 sub areas, including: high-end software instry, artificial intelligence instry, block chain instry, big data instry, cloud computing instry, etc. Among them, in the field of blockchain instry, we should strengthen the research and development of technologies such as consensus mechanism, data storage, network protocol, encryption algorithm, privacy protection and intelligent contract, support the development and opening of the underlying platform of blockchain, cultivate and expand the open source community of blockchain technology, and strive to take the lead in breaking through and focusing on the original innovation of basic theory and core technology of blockchain Seize the commanding point of technological development. Strengthen the research on blockchain standardization and enhance the international discourse and rule-making power. Support the promotion of blockchain demonstration applications with high concurrency, high throughput, low latency and high reliability, and explore the application demonstration of blockchain in the fields of smart city, digital government, finance, people's livelihood, deposit, digital property transaction, credit system construction, etc

since the development and Reform Commission incorporated the blockchain into the new infrastructure, all provinces and cities across the country have ushered in the upsurge of blockchain policy. Driven by policy support and technological evolution, the development of the blockchain depository market has accelerated. At present, electronic data storage based on blockchain technology is widely used, providing a perfect solution for electronic contract, intellectual property protection, judicial service, anti-counterfeiting traceability, etc< since 2014, easysaving has been deeply engaged in the research and development of underlying technology and application innovation of blockchain. Based on the electronic data preservation of blockchain, easysaving has launched a number of brands, such as Junzi signature in the field of blockchain electronic signing, micro right in the field of blockchain intellectual property protection, and zhongzhengbao in the judicial field of blockchain Internet. Through the "blockchain + justice + application", we can help more enterprises to realize the transformation and upgrading quickly, enabling and increasing efficiency for the rapid development of digital economy

4. With e-Cert technology, it is still in the stage of science popularization for enterprises. Different service platforms have their own proct characteristics. It takes time for enterprises to understand it. It is difficult to provide technical services and science popularization for enterprises

5. Blockchain technology has the characteristics of decentralization, tamper proof and time stamp proof, which naturally meets the requirements of electronic data storage. 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. Blockchain certificate storage can make data consistent storage, tamper proof and non repudiation proof, and ensure the security of data transmission and access with the help of cryptography. Cipher finance mimacaijing focuses on blockchain information.

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

7. The existing rules of electronic data are
1. The cost of replication is low, and the replication is abrasion free, which can be accurately replicated. The uniqueness of matter in the atomic world is impossible in the bit world
2. Electronic data has no time trace. With the passage of time, the electronic data carrier may change, but the data itself will not change, so it is impossible to compare the time sequence of two electronic data. Compared with the atomic world, the information world lacks a real time dimension
3, electronic time is easy to change, change and lose. There is no "credible" time in bit time, and electronic data can only be a mapping of the information of the atomic world
with the help of blockchain, the security network records the metadata of data preservation on the blockchain, combines encryption algorithm, digital certificate and other technical means, and constructs a more secure and credible trusted mapping from bit world to atomic world, which can prevent hacker attacks< As a result, a complete electronic data link is formed: private certificate + notarization + electronic signature + blockchain = complete electronic data link
development trend of security instry
in the DT era, cloud technology has brought revolutionary changes to electronic evidence, and electronic evidence has been listed in Criminal Procere Law and civil procere law. On January 1, 2013, electronic data as evidence has come into effect in the civil procere law. The demand for electronic data forensics in different regions and instries is growing rapidly, as well as the demand for electronic data preservation and forensics.

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

9.

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
