How to check that the exchange is decentralized

1. Centralized exchange and decentralized exchange have their own advantages and disadvantages, and the difference is very obvious. Let's take a look at the centralized exchange first. To put it bluntly, the trading mechanism of the centralized exchange is actually similar to our traditional stock trading
the first step is to register (open an account) and set the password. The second step is user authentication (KYC). The third step is to recharge. Here comes the key. The third step is the most important. Because you need to charge money to your address in the exchange before you can trade money in the exchange. The address of the exchange is actually a wallet address, but the ownership of the wallet is not the user, but the exchange, that is to say, the private key of the address, you don't have it!!! Do you understand the meaning

well, after recharging, the transaction is finished. The user submits the instruction (hanging order) to the server, and then the exchange will be responsible for matching the transaction, which is exactly the same as the stock. The last is cash withdrawal (withdrawal of currency). Users can send instructions to transfer the currency from the exchange address to their wallet address. The above is the trading mechanism of the centralized exchange. In these steps, all actions will have costs. No matter you recharge, trade or withdraw money, gas and handling charges can't escape
then let's look at the decentralized exchange. The trading mechanism is different from the centralized exchange. The first step is to register (open an account) and set the password. It doesn't make any difference. But then it's a little different. KYC is not used. But because there is a private key, the ownership of this address is completely controlled by the user. The second step is recharging. This is not very different from the centralized exchange. You still have to make your own gas
after recharging, we can also trade in the decentralized exchange. Users can also register orders, and exchanges will also be responsible for matching transactions, but the matching is done by smart contracts. Finally, cash withdrawal (withdrawal of currency) is initiated. After withdrawing currency, users can directly transfer the currency from the address of the exchange to their wallet address. This step is the same as that of the centralized exchange
the above is the trading mechanism of centralized and decentralized exchanges, and the difference between them is also obvious. Because all currencies in the central exchange are under its control, the trading efficiency is very high, and it is similar to the stock trading process, convenient and suitable for most users. Conversely, the risk lies in this. If the exchange itself loses its integrity or is attacked by hackers, the user's capital (currency) is not guaranteed
all the transaction processes of decentralized exchanges are completed by smart contracts, so the transaction efficiency is relatively low (TPS of blockchain technology has always been a soft rib), but relatively, the capital (currency) is completely in the hands of users, so the security is relatively high. In addition, there are also KYC, where KYC is needed for centralization, but not for decentralization, and the security of personal information is relatively high. Compared with the decentralized exchange, the advantages of the centralized exchange lie in the trading depth and the number of users, which are unmatched by the decentralized exchange
therefore, centralization and decentralization have their own advantages and disadvantages. It depends on the user's own choice. They like convenient, centralized, secure and decentralized.

2. Decentralized exchange refers to the virtual currency exchange. Investors are expected to choose carefully. First of all, there is no formal virtual digital currency exchange or formal trading platform in China, so the state does not recognize virtual digital currency. If investors are involved, they may lose everything.

3. Compared with centralized trading platform, what are the advantages and disadvantages of decentralized trading platform
since 2013, many decentralized trading platforms have emerged. Different from the centralized trading platform, the decentralized trading platform does not need to register an account, and can participate in the transaction by using the personal digital asset account
secondly, every transaction of the decentralized trading platform is carried out through the blockchain, and it needs to wait for the confirmation of the blockchain before the transaction is successful. At the same time, the decentralized trading platform is not responsible for keeping users' assets and private key information. On the one hand, it avoids the moral hazard of the trading platform, on the other hand, it requires you to keep your private key well
e to the low liquidity and slow transaction processing of decentralized trading platforms, the total transaction volume only accounts for 0.03% of the global total transaction volume of digital assets. At present, the tokens of airswap, kyber, 0x and omisego can be traded on huobi.pro.

4. Yes

5. Many people are optimistic about the decentralized exchange. The private key is in their own hands and they enjoy complete control over the user's assets. However, e to the congestion of Ethereum's public chain, the trading experience of the decentralized exchange on Ethereum is not very good and slow. At present, the most promising is the X protocol, but if the problem of Ethereum is not solved, its application problems can not be started at all
in comparison, the decentralized exchange based on EOS is much better, because its TPS is fast enough to handle the decentralized application at the present stage, and its speed is much better than that on Ethereum. Whaleex, in particular, is very smooth in use, with fast transactions. It is not inferior to those centralized exchanges. Among all decentralized exchanges, whaleex is excellent
therefore, I think the decentralized exchange on EOS may break out faster than that on Ethereum, especially the whale exchange, which will be a dark horse. The smart contract of their home is also the only one that has passed the slow fog security audit. The security is particularly high and the use is assured.

No

all transactions of European Union are virtual currency transactions

in a decentralized exchange, users' assets are directly held in their wallets, which greatly reces the risk of loss of users' assets caused by theft or running away from the exchange. Matchmaking transactions completed through smart contracts and settlement and clearing completed on the chain not only enhance transparency, but also greatly rece dependence on central media

decentralized exchanges include all the decentralized value and asset exchange methods. Due to the lack of trust, in many existing trading scenarios, various forms of centralized exchanges are needed to provide trust guarantee, and blockchain technology will rece the cost of trust by building shapeless decentralized exchanges, Graally reshape the old value exchange system

extended materials:

precautions:

1. The real holder of digital assets is the user himself. He has absolute ownership and control over his own digital assets. He will not lose his own assets e to the theft of the exchange, which ensures the security of digital assets

2. Through open source smart contracts, asset custody, matchmaking and asset clearing are all put on the blockchain

3. Using smart contract to realize the trading mechanism of decentralization and distrust solves the internal operational risk, business moral risk, asset embezzlement and other risks that seriously affect the user's asset security caused by human factors in the centralized exchange

4. Because the user's account key is controlled in their own hands, the hacker attack is technically changed from centralized attack to decentralized attack on personal accounts, resulting in the decline of profit margin and the improvement of relative security

7. If it is truly decentralized, there will be only one dotc.pro, and the others are not truly decentralized. Dotc.pro, from transaction to transfer currency, is settled on the smart contract chain, not on other platforms

8. With the advent of the Internet of things, the number of Internet devices will increase several times. In the era of mobile Internet, mobile phones are the main networking devices, and the number of networking devices is about 4 billion. It is estimated that by 2020, the number of networking devices is expected to reach more than 25 billion. In addition, according to Alibaba cloud, the number of Internet of things connected devices will reach more than 20
billion in 2020. Overall, with the acceleration of the development of the Internet of things, the number of networking devices will be several times more than the existing mobile Internet
according to the data of the analysis report on market demand and investment opportunities of China's Internet of things instry segments issued by foresight Instry Research Institute, the scale of the global Internet of things market will reach US $200 billion in 2025; The number of Internet of things will reach billions, benefiting the whole value chain; The application of the Internet of things in various instries is deepening, giving birth to new technologies, which is concive to the transformation and upgrading of traditional instries
at present, the Internet of things application scenarios have formed a large particle (annual demand is more than 10 million) market, mainly in the fields of intelligent meter, mobile payment, smart car, smart grid and so on. Growth in these areas has led to major growth in the instry
the Internet of things extends the service scope of mobile communication, from people to people communication to things and people to things intelligent interconnection, which makes mobile communication technology penetrate into a broader instry and field. Facing 2020 and the future, mobile medical, Internet of vehicles, smart home, instrial control, environmental monitoring, etc. will promote the explosive growth of Internet of animals applications, and hundreds of billions of devices will be connected to the network to realize the real interconnection of everything;, And create an unprecedented scale of emerging instries, for mobile communications to bring infinite vitality. At the same time, massive device connections and diversified Internet of things services will also bring new technical challenges to mobile communications.
