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. 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. 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.

4. 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, cent and other projects are the only ones using blockchain technology.

5. Domestic digital currency wallets are basically not OK. Wallets are the natural enemies of centralized exchanges.
6. Can solve, bit box is a good application proof
7. The core of blockchain + is to graally eliminate all instries that need intermediary to do trust. At present, many central nodes and service platforms of the Internet are essentially trust mediators. Users can do shopping, traveling, ordering, paying and so on through the trust intermediaries such as Taobao, Didi, excellent step, American group, Alipay and WeChat payment.
but the Internet has never been static, and continuous evolution is the norm. In the future, people will have new trust dependence. Because the records of the blockchain can not be tampered with and are authentic, people's trust in the blockchain graally exceeds that of the centralized company. With the joint efforts of many blockchain enterprises and some traditional instries, the world will graally transition from a centralized trust driven to a system driven by algorithms and data. When the centralized trust intermediary is graally weakened, the system represented by blockchain will graally take over the operation mode of the whole world, and finally form the "disintermediated" system trust
therefore, blockchain is not only a technology, but also a story about the paradigm shift of world operation. Although the story is still a little far away, it has sprouted and initially developed
blockchain Internet will start from the instries most closely related to trust and traceability, and graally expand and expand until most instries are blockchain oriented and blockchain +
Puyin is a high-quality Tibetan tea asset, which is stored, identified, evaluated and authorized by three parties. It is a standard digital currency issued through encryption and digitization. Puyin implements the concept of "white paper on standard digital currency" in strict accordance with its operation guidelines, and sets a standard for asset digitization
