How does blockchain guarantee the authenticity of data

1. Private key~

2. The analysis of Chongqing jinwowo network is as follows:
each node on the blockchain can verify the integrity and authenticity of the account book to ensure that all transaction information is not tampered with, true and effective
every node on the blockchain keeps copies of all transaction information. When the number of data and participants on the blockchain is very large, the cost of modifying information will be very high. At least 51% of the computing power of the whole network is needed to modify information, and the modification cost may far exceed the expected revenue
when the information of some nodes is maliciously tampered with, other nodes on the blockchain will find the information that has not formed a "consensus" in a short time and maintain and update it.

3. Jinwowo, Chongqing: artificial intelligence has the ability to analyze massive data at high speed. As the basis of artificial intelligence, data must be accurate and safe, and there must be no forged data
if the blockchain technology is used, the authenticity and security of data can be guaranteed
by combining the two, consciousness chain forms a data pool, creates an efficient data exchange center, and finally constructs a three-dimensional and multi-functional artificial intelligence ecosystem.

4. The distributed architecture and tamper proof features of blockchain technology help to solve the problems of bill authenticity and information opacity. When participants need to check whether the bill has been tampered or transferred, blockchain can provide indisputable proof of consistency
digital currency also makes use of this feature of blockchain. Puyin is a kind of tea standard digital currency developed based on blockchain technology.

5. Laikelib blockchain infrastructure operation team analysis: blockchain technology is a breakthrough in network security, because it can ensure the highest level of data confidentiality, availability and security.

6. Chongqing jinwowo analyzes and solves problems in the following ways:
first of all, by using all data chains in the blockchain for prediction and analysis, the regulatory authorities can timely discover and prevent possible systemic risks. The decentralized characteristics of the blockchain can eliminate the information island in big data risk control, and improve risk control through information sharing

secondly, the distributed database of blockchain can improve the poor quality of big data risk control data, and solve the problems of data format diversification, data form fragmentation, lack of effective data and incomplete data content

finally, blockchain can prevent data leakage. Because the blockchain database is a decentralized database, any node's operation on data will be found by other nodes, thus strengthening the monitoring of data leakage.

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

8. The blockchain adopts one-way hash algorithm, and each newly generated block advances in strict time linear order. The irreversibility of time makes any attempt to invade and tamper with the data information in the blockchain easy to be traced, leading to the exclusion of other nodes, so as to limit the related illegal acts. In the future, jinwowo will continue to tap the value of blockchain technology in the commercial field, give full play to the advantages of big data services, and add value to user behavior.

9. In the blockchain, there is a core technology to do asymmetric encryption and authorization technology. The transaction information stored in the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy.

10. The main thing is the decentralization of blockchain technology. Because the blockchain relies on each node to achieve the maintenance of the system and ensure the authenticity of information transmission, it is based on distributed storage data, and there is no centralized management by a certain center. Therefore, the attack and usurpation of a certain node will not affect the healthy operation of the whole network.
