The difference between decentralized algorithm and traditional p

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. Yes, decentralization: no domain name, no server, no central account, no operator, open fund pool, never shut down the network, with chain contract, no real name registration, automatic distribution of benefits, no tampering with the system, no hacker attack
centralization: to apply for a domain name, you need a server, you need a central account, you need an operator, the fund pool is not open, you can close the network at any time, you have no contract on the chain, you need to register your mobile phone number, you need to apply for cash withdrawal, and hackers can attack.

3. E-money: the current e-money
traditional e-money: the e-money left by traditional ancestors in the past

4. Compared with the traditional centralized financial system, the decentralized financial platform has three advantages:
A. indivials with asset management needs do not need to trust any intermediaries, and the new trust is rebuilt on the machine and code
B. everyone has access, no one has central control
C. all protocols are open source, so anyone can cooperate on the protocols to build new financial procts and accelerate financial innovation under the network effect
defi is a relatively broad concept, including currency issuance, currency transaction, loan, asset transaction, investment and financing, etc
we regard the birth of BTC and other cryptocurrencies as the first stage of decentralized finance. However, the decentralization of currency issuance and storage only provides a point-to-point settlement solution, which is not enough to support the rich financial business. The rapid development of decentralized lending agreements in the past two years will have the opportunity to further open the financial system of the blockchain world and bring decentralized finance into the second stage<

5. Hello, it's a great honor to be here to answer your question. The following are some of my views on this issue. If there are any mistakes, please point them out. Start all
and enter the column
almost every supporter of encryption start-ups has a trend, that is, to use the decentralized value of blockchain technology to sell their business fundamentals
in this paper, we will explain the differences between decentralized financial agreement business and traditional business:
we will mainly discuss two aspects:
1) what is the real meaning of defi
2) what are the types and main differences of defi platforms< Users of traditional financial systems often want to build a system that is easier to access, more transparent, lower transaction costs and less dependent on intermediaries. To build such a more equitable financial system, banks, loans and derivatives must undergo fundamental changes. In addition, a decentralized ecosystem, such as defi, is needed. It promotes P2P lending, eliminates centralized control, and provides users with financial freedom
recently, in the field of cryptocurrency, there are many discussions about defi. It provides financial services to the world: loans, derivatives and other procts. Moreover, the role of traditional financial intermediaries has weakened, or even failed to play a role. Proponents of a decentralized financial system see defi as a good alternative to traditional lending. Some have called it the future of borrowing
defi is built on public blockchains such as bitcoin network and Ethereum. It has become one of the "core drivers" on the Ethereum network. By using unlicensed distributed networks, the defi platform converts financial procts into untrusted protocols that can be accessed by anyone anywhere in the world. People who don't have an account in the bank can also use the defi solution to loan and borrow assets, as well as to trade with financial instruments
open source platforms provide users with great benefits, including transparency, cheap cross-border transactions, no credit checks and less censorship. Anyone can carry out financial activities because there is no geographical restriction<
the degree of decentralization of defi
in recent months, the introction of defi solutions has proliferated. They have different models and their degree of decentralization is also different. Compared with other models, some defi models have poor dispersion. This is because only a few of their components are decentralized, while the rest are still centrally controlled by the company
the establishment of agreement, non trust, price supply, determination of interest rate, provision of liquidity of margin call and start-up of margin call are the key components of defi agreement. They determine the degree of decentralization
if there are a large number of decentralized components, then the defi protocol is more decentralized than other models. Such a protocol will give users complete control over their digital assets and get rid of centralized control. So far, there is no single defi protocol that disperses all components
each defi protocol is assigned a category according to the number of distributed components:
centralized finance (cefi)
defi solutions are usually unmanaged, which means that users can control their funds and be responsible for their security. Instead, cefi is hosted. The central system is responsible for keeping the assets of users and ensuring the safety of users' funds
when it comes to loans or loans, users can't control any aspect of funds. The interest rate is determined by the central government, and the liquidity of margin call is provided by the central system or authorities. Cefi procts use centralized price supply, and it is also permitted to issue margin call. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!

6. Centralized cloud service is a large amount of data concentrated on a unified cloud platform. Decentralized cloud service is that data storage is not in a center, but scattered in all nodes around the world. Decentralized cloud services derive more decentralized applications. In terms of decentralized cloud technology, China's Amway cloud is in the forefront of the world. Its decentralized cloud platform xnmatrix, which combines the resources of top universities such as Oxford and Berkeley, as well as downstream enterprises such as global miners and AI robots, is building the world's largest decentralized cloud platform.
