Is block chain capital safe

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. There must be risks, and they are high risks, because high returns are always bound with high risks. You are a little rookie who doesn't know anything. Can you make money like other people's old birds? If you are just interested in the coin circle, I suggest you don't be reluctant to spend a small amount of money to add a pay circle of the coin circle. For example, the group of Li Xiaolai, the big money in the coin circle, once cost as much as 5 million yuan. There are also some old cats and baoerye groups, but they are too far away from us ordinary people. But if you have a lot of money, it's a good deal. If it's only tens of thousands, it's suggested to add some groups with high cost performance, such as the payment group of fire chain blockchain, Zhongshen blockchain club, which are reliable, and there is a free trial period.

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. Easy chip EAS blockchain insurance can guarantee its own security, and you can rest assured. It is also transparent and automatic.

7. It's useless to just delete, because there is no solution to the vulnerability
the suggestion is to redo the system, and then find the guardian God to reinforce the system security for you, so as to completely plug the loopholes.

8. Blockchain is just a technology, not safe or insecure. It still depends on the platform technology. The current blockchain is just a cover. In fact, there are not many places to use the blockchain
bitcoin, Ethereum, decent and other projects only use blockchain technology.

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.

10. The more you spend, the more platform you have. Is blockchain safe for consumers' money. I don't think it's reliable
