Data uniqueness of blockchain

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,

in essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness

however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay

2. 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.

3. A timestamp, usually a sequence of characters, uniquely identifies the time of a moment. Digital time stamp technology is a variant of digital signature technology
time stamp refers to the total number of seconds from 00:00:00 GMT on January 1, 1970 (Beijing time: 08:00:00 GMT on January 1, 1970) to now
to put it simply, a time stamp in a blockchain means that whatever happens at a certain time will be recorded on the blockchain. For example, the blockchain content publishing platform decent, when someone publishes some information on it, the information will be recorded from the moment of release, which can't be changed. The time of occurrence is fixed and can't be changed.

4. 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.

5. 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.

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.

7. Blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid. When the concept of blockchain was hot, many related top domain names were registered and used as blockchain platforms.

8. Blockchain is a kind of public and distributed account book. Different from the centralized recording method, its data source is single, and the data records are consistent, so it can create a clearer tracking channel in each link
in the future, jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data.
