Comparison of decentralized exchanges

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. 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.

3. 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.

4. First of all, the decentralized exchange mainly carries out transaction matching, asset clearing and settlement on the chain. User assets are managed by smart contracts and controlled by users. The exchange does not touch user assets
secondly, the biggest value of the decentralized exchange is that users have absolute control over their own assets, and all transaction data and records will be linked through the blockchain smart contract, so as to ensure the openness and transparency of transactions and greatly rece the trust cost of users to the exchange
thirdly, it is very difficult for hackers to steal user assets unless they can get each user's private key. Even if the exchange's private key is leaked, the user's assets cannot be transferred without the user's private key, so it is very safe. With decentralized exchanges, you no longer have to worry about the risk of losing or stealing money
for this reason, with the graal maturity of the underlying technology of blockchain, decentralized exchange has great development potential, which is the trend in the future.

5. I think it's similar. I've seen i-swap recently. I'm going to get to know it.

6. To tell you the truth, it's very slow. It's also related to the development of the instry. After all, the underlying public chain TPS is so slow, let alone the above applications. However, everything is not absolute. Whaleex, a decentralized exchange based on EOS, is very fast and not slow at all. They have independently developed the matchmaking engine under the million TPS chain, and the transaction efficiency is very fast. They can complete the transaction quickly from the order registration to the transaction, which also reflects that their transaction depth is very good and the liquidity is very good.

7. For example, the decentralized OTC trading platform of gotc is very good. Many friends around me, including me, especially like to play currency. Recently, they have been playing on this platform. Gotc platform is not owned by any company, and a third party will assist in platform updating and answering related problems. Gotc implements strict risk control management and operates stably.

8. Centralized trading platform, because the transaction data is not on the chain, so as long as there is a matching opponent single, the transaction speed is extremely fast. At the same time, the operation steps of the centralized trading platform are simple, the threshold of use is low, and it can provide rich trading pairs, so more users will choose the centralized trading platform, and more users will have better trading depth, which further promotes the transaction speed of orders on the centralized trading platform
e to the need to link transaction data and wait for miners to pack and broadcast transaction confirmation, the transaction speed of decentralized transaction is slow. The operation steps of decentralized trading platform are relatively complex, and the use threshold is higher. When it comes to the transaction of different blockchain assets, such as bitcoin and Ethereum, it needs more complex cross chain technology, and many decentralized trading platforms can't realize it, so the supported transactions are less than the centralized trading platform
celletf is a comprehensive application platform for defi (celletf. IO), which relies on the deployment of Ethereum public chain, including a number of smart contracts / protocols, passive bidding mechanism and ETF primary and secondary al market architecture. With only one site, it can embrace the unlimited possibilities of defi.

9. Jp110 bar

get a ruler shield, add a blue bottle synthesis is the jeweler's preference

clothing and red bottle is the jeweler's whale

attention is the choice of your own materials, you should be able to make 4 holes

for example, you throw a blue bottle with a troll hole, although it is a jeweler's preference, However, the maximum number of holes in the item itself is 3

so it's 3 holes

if the jeweler is stable, he should add yellow bottles. Anyway, if you want to gamble with super high defense clothes, get an ancient armor, use white bottles, make it super strong, make it 15ed all the time, then throw poison bottles, make it transparent, and then put 4 "Rune" to get 4S, If you want 3S, put 3#

if you can't say 4S, it should be your choice of materials, and you should choose clothes that can get 4S, but the essence of all the clothes can be 4S. Do you choose the Mage Armor of ETH?

10. The precious metal exchange is only a company, and the precious metal exchange center belongs to a region including the precious metal exchange.
