区块链证据是什么意思?,区块链技术在什么证据领域主要有两个应用优势

『一』 Micro-copyright screen recording evidence collection, blockchain on-chain storage, how to help the entire evidence chain to provide credible evidence

With the widespread application of "Internet +" in various industries In various industries, the issue of intellectual property protection in the Internet environment has become increasingly prominent. According to the China Judgment Documents Network, as of December 2022, as many as 74,560 judgment documents on "electronic evidence" can be retrieved. Electronic evidence has increasingly become an important weapon for safeguarding rights.
Article 11 of the "Regulations of the Supreme People's Court on Several Issues Concerning the Trial of Cases in Internet Courts" clearly states: Early defense evidence collection through electronic signatures, trusted timestamps, hash value verification, blockchain, etc. If its authenticity can be proven by fixed and tamper-proof technical means or through electronic evidence collection and storage platform certification, the Internet Court shall confirm it.
Microcopyright pioneered the "blockchain + judicial + intellectual property protection" model. It developed screen recording and evidence collection functions in response to frequent infringements on the Internet. , audio, chat records on social software, pictures, articles, etc.) to conduct screen recording and evidence collection at the first time, and use the block chain technology to solidify and preserve the electronic data containing infringing content to generate undeniable and tamper-proof electronic evidence. , to facilitate the production of evidence and rights protection.

『二』How to use blockchain to solidify, access, and verify evidence and improve the effectiveness of evidence

Using blockchain to solidify, access, and verify evidence can Improve the effectiveness of evidence and prevent evidence from being tampered with or lost. The following are the specific steps:

1. Evidence solidification: record the hash value of the evidence on the blockchain, and use the non-tamperability and decentralization characteristics of the blockchain to ensure the integrity of the evidence sex and authenticity. For example, a public chain or a private chain can be used to solidify evidence. The public chain can better ensure the fairness and transparency of the evidence, while the private chain can better protect the privacy of the evidence.

2. Evidence access: Utilize the distributed storage characteristics of the blockchain to store evidence on multiple nodes to ensure the reliability and durability of the evidence. For example, decentralized storage protocols such as IPFS (InterPlanetary File System) can be used to store evidence, and smart contracts can be used to control access rights to evidence.

3. Evidence verification: Taking advantage of the decentralized and open and transparent features of the blockchain, the authenticity and integrity of the evidence can be easily verified. For example, you can use a blockchain browser to view the hash value or transaction record of the evidence, or you can use smart contracts to verify the authenticity and integrity of the evidence.

It should be noted that the use of blockchain for evidence solidification, access, and verification needs to comply with relevant laws, regulations, and privacy protection principles. At the same time, the security and reliability of the blockchain technology itself need to be considered.

『三』What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each block of data contains a The information of batches of Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

(3) Extended reading of blockchain evidence chain

Characteristics of blockchain:

1. Deposit certificate

The "non-tamperable" feature of blockchain provides a solution to the problem of "certificate storage" in economic and social development. As long as the authenticity of the on-chain information and data can be ensured, the blockchain can solve the problem of "storage" and "certification" of information.

For example, in the field of copyright, blockchain can be used to store electronic evidence, which can ensure that it is not tampered with, and can link original platforms, copyright bureaus, judicial agencies and other parties through distributed ledgers. The banquet greatly improves the efficiency of Yinxin Bank in handling infringements.

2. Sharing

The "distributed" characteristics of the blockchain can break through the "data barriers" between departments and achieve information and data sharing. Different from centralized data storage, the information on the blockchain will be distributed to each node through point-to-point broadcasting, and all information can be "truthfully recorded" through "whole network witness".

『四』How does Junzi Sign create a closed loop of the electronic contract evidence chain to make contract signing more reliable and secure

Electronic contracts are a major change in the habit of making traditional paper contracts. Reliable electronic contracts Contracts have more advantages than paper contracts in terms of simplified conditions for conclusion, standardized storage and anti-tampering risks.
An effective electronic contract includes four elements: generation (time stamp), storage (third-party storage), extraction (Gonglu age certificate) and identity authentication (electronic signature). It is necessary to form a certified electronic contract. A closed electronic evidence chain with valid signing identity and untampered content.
Since electronic data has the characteristics of real-time generation and easy loss, the Junzisign blockchain electronic signing platform uses real-name authentication, blockchain, timestamps, full evidence chain and other technical means to create electronic contract data authentication and certificate storage , evidence collection, verification/evidence and other evidence chain closed loop to ensure that the contract signing party is trustworthy, the signing behavior is valid, the results cannot be tampered with and the whole process is notarized in real time, improving the evidence effectiveness of electronic contracts.
1. Authentication: multiple authentication methods, the signing subject is trustworthy
Junzisign connects with multiple CA institutions, adopts CA digital authentication technology, and provides a variety of identity authentication methods, such as liveness detection and face recognition , SMS verification, etc., to ensure the true identity and intention of the contract subject, and use blockchain certificates and timestamps to solidify the data of the entire signing process, ensuring that the contract data is not tampered with, while preserving the entire signing evidence chain.
2. Evidence deposit: pre-intervention, real-time data preservation and preservation
Intervention before the contract signing occurs, and real-time data preservation and preservation. Through the "preservation chain", the key data of the electronic contract uploaded by the user is generated as a unique digital fingerprint at the first time, synchronously participates in the node consensus, stores independently, and backs up each other. At the same time, key details of the entire process of contract signing and operation are protected by the full evidence chain. Open it early and form a complete evidence chain to ensure data security and traceability.
3. Evidence collection: online evidence collection, real-time notarization throughout the entire process
For the extraction of electronic contract data, Junzizhuan realizes the simultaneous supervision and coordination of notary offices, arbitration committees, judicial appraisal institutes, courts and other institutions through the "preservation chain" Notarize, verify and display evidence online, and issue notarization deeds, notarized custody letters and other judicial documents online to improve the validity and credibility of evidence.
4. Verification/evidence: verify evidence in real time and provide evidence in court
After the contract is signed, an "electronic data storage certificate" can be generated for each electronic contract data, and users can scan the code in real time Inspect and compare evidence, including contract documents, preservation subjects, timestamps, HASH values ​​and other data information to ensure the uniqueness and authenticity of the original electronic data. Relevant evidence can also be displayed to the judge in court to reduce the burden of proof on the parties and improve Efficiency in rights protection and accelerated dispute resolution.
Junzi Sign is based on blockchain certificate storage and full evidence chain technology, which can ensure that every electronic contract data signed by users on the platform can be witnessed by all nodes, the entire process can be traced, all data can be verified, and all links can be verified Proof of trust makes contract signing safer and more reliable!
