Ranking of blockchain decentralized exchanges
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.
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.
x protocol: a point-to-point open protocol running on Ethereum. The protocol aims to become a general open standard, as a basic mole that can be combined with other protocols to drive more and more complex blockchain applications. However, Ethereum is famous for its congestion, so its current situation is not very good

Road printing protocol: decentralized transaction protocol of class X. The on chain smart contract is responsible for asset custody, matching and transaction, and the off chain smart contract is responsible for order matching. It has an on chain trading loop matching technology, which encourages the exchange to match the transaction path with the maximum discount, so as to save transaction costs for users and make the exchange profitable at the same time. But on the other hand, it also increases the complexity of smart contract and the execution cost of Ethereum transaction, and the effect in practical application remains to be seen
there are also kyber, idex, bitstocks, etc. decentralized exchanges are the trend in the future, so there are still quite a few in the market. But comparatively speaking, I still think whaleex is the most reliable.
At present, there are few blockchain Unicorn companies, and the development of blockchain is still in its infancy, which needs a long-term development process
