The decentralized exchange of coin an investment

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. Going to the center means that there is no country, just like bitcoin. Now the country has banned bitcoin, as you can imagine

3. The core difference between centralization and decentralization is whether the private key is in the hands of the user. The decentralized platform can protect the user, such as celletf (celletf. IO), which solves the security problem of the user's assets, but the operation is relatively simple.

4. Coin an decentralized trading platform is the fastest trading engine on the chain, and all transactions are completed on the blockchain. Through decentralized operation, it can handle more than enough transactions of binance.com. Users use the private key for transactions, and no one else can modify the transaction. Currency security chain uses the blockchain consensus protocol BFT based on tendermint, under which transactions only need to be confirmed once. The block time of the transaction is less than 1 second, that is, the time required for the completion of the whole transaction is less than 1 second
there are a large number of user interfaces on coin an decentralized trading platform. Anyone can create an interface, and many people have already done so.

5. Coin an, like bat and faamg, is highly subversive and pioneering. If we say that building a public chain and a decentralized exchange is a self revolution, Yuan'an is already at the head of a centralized exchange, and has invested a lot of energy in building a decentralized exchange and launching an open platform, many people may not understand. In fact, coin safety has been in the process of decentralization and never stopped. Complete decentralization is the ultimate form of coin safety.

In July 2017, Zhao CHANGPENG founded coin an. It took him six months to build it into the top three in global digital asset trading, with 6 million registered users. More than 30% of us digital currency players are users of coin an, which is now the largest virtual currency trading in the world

extended information:

value and repurchase mechanism:

1. Preferential dection of transaction fees of coin security platform

for users who participate in transactions on coin security platform, no matter what token they trade, if they hold enough BNB, the system will discount the transaction fees, According to the market value at that time, the equivalent amount of BNB is converted, and BNB is used to complete the payment of handling charges. Discount rate 50% 25% 12.5% 6.75% no discount

2. Buy back mechanism:

after the launch of the coin security platform, we will buy back 20% of the net profit of the current quarter of the coin security platform for BNB every quarter. The bought back BNB will be destroyed directly, and the buyback record will be published at the first time. Users can query through the blockchain browser to ensure transparency until the total number of BNB is 100 million

3. Decentralized trading "fuel"

in the future, BNB will also be the fuel of coin an's decentralized trading platform on the chain. BNB is needed when using coin an decentralized trading platform. It includes various functions such as dection of service charge and reward

7. Bittok is not a decentralized exchange. It is a centralized exchange just like Huo coin, OK, and coin an.

8. Zhao CHANGPENG said that currency security is promoted by both DEX and CEX. In the future, if the DEX increment is faster, the center of gravity will be adjusted accordingly.

Shanghai Aegean shopping park is a commercial complex of cultural experience and a new commercial landmark in Shanghai. With a total construction area of 550000 square meters, it is a cultural, emotional, ecological and modern business center. Its completion is of great significance to improve the grade of the whole Wuzhong Road business district

the "sea world" music fountain has more aestheticism There are six performances in the music fountain of the world every day
10:00 / 12:00 / 15:00
18:00 / 19:00 / 20:00
each performance lasts for 10 minutes ~

10. Coin security intelligent chain is open source, and the nodes have been open for a long time. It is a real public chain. Backed by coin security ecology, it may not be so decentralized.
