Real time security of blockchain Technology

1. Chongqing jinwowo analysis: the information security advantages of blockchain technology are as follows:

first, through the application in the field of digital currency, blockchain provides a solution for the flow of capital flow (or capital flow) information on the Internet

secondly, blockchain solves the problem of right confirmation in the transaction process through encryption and reference of distributed ledger

thirdly, blockchain determines the exchange of digital assets through the technology of consensus mechanism.

2. Private key~

3. 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.

4. Improving network security
blockchain is a decentralized and distributed electronic classified accounting method based on the model of providing absolute security and trust. Using encryption technology, transactions are recorded chronologically and publicly, and each block has a timestamp and a link to the previous block. Importantly, these digital "blocks" can only be updated through the consensus of all participants, and data interception, modification and deletion are almost impossible.

5. When it comes to the nature of blockchain, several key words are familiar. For example, decentralization, distrust, consensus mechanism, asymmetric encryption, distributed accounting, tamper proof, absolute transparency, openness and so on. At the same time, some teaching posts also list the structure of blockchain, such as data layer, network layer, consensus layer, incentive layer, contract layer and application layer
however, it's easy for people with an eye to see why there is no security layer? In fact, several key features of blockchain have already solved the security problem. First, the blockchain uses asymmetric encryption technology. In fact, encryption and decryption are different keys, namely public key and private key. In short, the public key is open to the public, while the private key is absolutely confidential
secondly, distributed bookkeeping is a way for blockchain to store data. It can also be understood as distributed storage, which is consistent with the concept of decentralization. In the form of ledger, there is no central ledger in the network, and the ledger is stored in each node. Each node is not only independent, but also can act as the central node. Therefore, the central node will not be attacked, leading to the loss of core books or data, and the whole network will not be paralyzed
moreover, tamper proof is the basic feature of blockchain. As long as the chain can not be modified, and can not be deleted. If it needs to be changed, based on the principle of transparency and openness, the whole network and all nodes need to be informed. Therefore, under the democratic mechanism, the possibility of tampering with data at will is very low. Therefore, blockchain technology is applied in various instries, such as finance, payment, traceability, games, etc., such as the network "universe", Tencent's "come together to catch the demon", and Zhongan Huanyu blockchain "Dr dragon hunt" are the safe and high-quality procts under the blockchain technology.

6. 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.

7. There are patches
this problem is actually very simple
your graphics card is OK! But the vertical synchronization of the graphics card is not off, so the FPS is very low. You can turn off the vertical synchronization in the properties of the graphics card
it must be this problem
the properties of the graphics card can be found by right clicking on the desktop, and then properties - Settings - Advanced<

vertical synchronization is off
in the 3D settings of the graphics card

8. According to its own development experience and technical characteristics, blockchain technology laboratory summarizes the following aspects: 1; 2. Use the relevant principles of cryptography to verify the data to ensure that it can not be tampered with; 3. Multiple private key rules are used to control access rights.

9. The answer to this question is yes, because the blockchain technology has a great feature, that is, the information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, Therefore, the data stability and reliability of blockchain are extremely high. For example, jinwowo group can provide big data services with blockchain as the underlying technology, and its encryption technology can fundamentally ensure the security and storage of data.
