Is LBA blockchain secure

1. Sharing source: DTV
the centralized trading platform covers the whole trading process including account opening, recharge, automatic transfer and transaction withdrawal. That is to say, when we put our digital assets into the address of the trading platform, the trading platform becomes the trustee of our digital assets, and the control of the actual assets is in the hands of the trading platform
different from the centralized trading platform, the decentralized platform does not need to register an account. It only needs to undertake the responsibilities of asset custody, matching transaction and asset clearing, and does not need to provide non trading function, account system, kcy and legal currency exchange functions like the centralized exchange; On the other hand, in the decentralized trading platform, all operations are realized through smart contracts, and this transaction needs to wait for the confirmation of the blockchain before it is successfully completed

based on the above attributes, the decentralized platform avoids the moral hazard of the trading platform and the centralized attack of hackers to a certain extent. However, in this trading mode, the security of assets depends on the users themselves.

2. Because each block contains its own hash value and the hash value of the previous block, changing a hash value will invalidate the rest of the blockchain
if you have problems with blockchain, you are welcome to chat in private~~~~~

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. Tencent must be the security leader of the blockchain, with security guaranteed, and refine the public components of the city level blockchain application to meet the landing needs of the trusted blockchain instry in different scenarios.

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. If the use of the characteristics of blockchain, such as decentralization, open sharing, authenticity, reliability and non tampering, is applied to proct traceability, it will undoubtedly be a great cause of benefiting the people and realizing China's integrity in a society where fake and shoddy procts are rampant. The emergence of traceability chain mall only sells authentic procts with traceability anti-counterfeiting technology as the core. By giving each proct a unique "China traceability chain. Com" traceability anti-counterfeiting certificate, the procts are added with the nature of traceability to protect the quality and safety of authentic procts and the legitimate rights and interests of consumers.

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. At present, many friends are in asproex (Apollo). The management of their family is composed of blockchain elites, bank executives and blockchain technology teams. They have rich experience in the blockchain instry and can learn more about it.

9. It can be said that it is very unsafe. The technology related to blockchain wallet has lost its original technical meaning in China. Now it has been reced to a means of money. Therefore, we must be very vigilant in this aspect. Anyway, I personally don't believe it.

The investment value of blockchain

1. blockchain is considered to be the most disruptive technological innovation since the invention of the Internet. Blockchain integrates cryptography, economics, game theory, computer science and other disciplines. It has the characteristics of irreversible transaction and data tampering. It has commercial value in many fields. Its application research has expanded to finance, energy, logistics, ecation, culture and social services

2. blockchain technology will create opportunities for the development of cloud computing, big data, Internet of things, artificial intelligence and other new generation information technology, which can comprehensively promote the upgrading of information technology and realize the leapfrog development of information instry

3. Privacy Protection cryptography ensures that the unauthorized person can access the data, but it cannot be resolved

4. the following business features include trustworthiness: blockchain can provide a natural and feasible distributed ledger platform without the need for additional third-party intermediaries

5. enhance security: blockchain technology is concive to safe and reliable audit management and account clearing, recing the possibility of crime and various risks
