Decentralization and P2P

1. The four well-known decentralized loan agreements are compound, Dharma, dydx and maker, We summarize it into three modes:
(1) P2P matchmaking mode

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system
Dharma and dydx are peer-to-peer agreements to match borrowers and lenders. Therefore, the number of loans and borrowings based on the two agreements is equal
for example, in Dharma, smart contracts act as "guarantors" to evaluate the asset prices and risks of borrowers. The creditor decides whether to loan to the borrower according to the evaluation results provided by the "guarantor". At the same time, when the borrower fails to repay on time, the "guarantor" will automatically carry out the liquidation procere. The maximum borrowing period of Dharma platform is 90 days, and the loan interest is fixed. The lender's funds are locked ring the loan period, and only after matching with the borrower can it start to earn interest
dydx protocol is also a P2P mode, but the main difference between it and other lending platforms is that dydx also supports other transactions besides borrowing and lending, such as futures trading. When a trader opens a position in dydx, he or she will borrow margin and reach an agreement with the lender on the terms through the platform to conct margin trading. Therefore, the target customers of dydx are mainly margin dealers. The interest of the dydx platform is variable, and there is no lock-in period or maximum term for users to borrow money on the dydx platform< The first mock exam mode of BR / > (2) is (3) liquid pool trading
take compound as an example, borrowers and lenders trade through the liquid trading pool instead of matching with counterparties. The interest rate of each loan and loan is determined by the liquidity of the pool, that is, the ratio between the total amount of money provided by the lender and the total amount of money demanded by the borrower. Compound doesn't set a fixed loan term, so the lender can deposit the funds into the loan pool, continuously earn interest, and withdraw the assets at any time. The borrower has an unlimited contract period

according to market research, as of February 20, 2021, the total borrowing volume of the decentralized mortgage market hit an all-time high of US $8 billion for the first time. Decentralized lending market is a network system based on smart contract, where cryptocurrency holders can lend their assets / certificates on the chain to others to make profits.
currently, the top three defi protocols in the total amount of borrowing are:
1, compound: the total amount of borrowing is 4446012599 US dollars, accounting for 55.60%
2. Maker: the total amount of borrowing is 2335968433 US dollars, accounting for 29.21%< 3. AAVE V1: the total amount of borrowing is 643772395 US dollars, accounting for 8.05%<

2. Decentralization is idealism. Although there is no decentralized P2P platform at present, with the development of blockchain technology, there is a high probability of decentralized peer-to-peer lending in the future
centralization has the advantage of centralization, which should not be too one-sided.

3. Decentralization, the distribution and circulation of network gold, through the open-source P2P algorithm. Without issuers, it is impossible to manipulate the number of issues.

4. 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!

5. P2P means peer-to-peer, and P2P network is a peer-to-peer network scene, characterized by decentralization. Blockchain is a technical means for the development of P2P network. It can be simply understood that a block is an account book that records all the information generated by the whole network in a certain period of time. In the P2P network, the data exchange and synchronization between each node need huge computing power, and the block technology is born to solve this problem.

6. There are many stream processors. Just look at the specifications

7. It's no different. You can use digital currency. It has to be said that the difference is that traditional P2P is centralized and has the risk of running away. Defi is decentralized. Smart contracts are executed automatically. There is no risk of running away. The biggest difference is that the intermediary link is removed, and the income is much higher than that of traditional lending procts.

8. Different, popular saying is, thunder is the same place, multithreading plus fast back. Too many people, too slow to connect. P2P, like BT, electric donkey and so on, can be in different computers at the same time under the same file back, so it is more people fast..

9. The concept of P2P

P2P is the abbreviation of peer-to-peer. In English, peer has the meanings of "peer", "colleague" and "partner". In this way, P2P can be understood as "partner to partner", or peer-to-peer networking. At present, people think that it has a bright future in enhancing people's communication, file exchange, distributed computing and so on

in short, P2P directly connects people and enables people to interact directly through the Internet. P2P makes communication on the network easier, more direct sharing and interaction, and truly eliminates middlemen. P2P means that people can directly connect to other users' computers and exchange files, instead of connecting to the server to browse and download as in the past. Another important feature of P2P is to change the Internet's current big website centered state, return to "decentralization", and return power to users. P2P seems to be very new, but just as B2C and B2B transplant common things in the real world to the Internet, P2P is not new. In real life, we communicate face to face or by telephone according to P2P mode every day

even from the perspective of network, P2P is not a new concept. P2P is the foundation of the overall Internet architecture. TCP / IP, the most basic protocol of Internet, has no concept of client and server. All devices are the equal end of communication. Ten years ago, all systems on the Internet had both server and client functions. Of course, the later developed software based on TCP / IP does adopt the client / Server Structure: browser and web server, mail client and mail server. However, for servers, they are still peer-to-peer networking. Take e-mail as an example, there is not a huge and unique e-mail server on the Internet to handle all e-mails, but peer-to-peer e-mail servers cooperate with each other to send e-mails to the corresponding servers. In addition, email between users is always a peer-to-peer communication channel. Of course, but in the past five years, the development of the Internet has at least distanced itself from P2P on the surface, and most of the nodes on the Internet can not communicate directly with other nodes. Napster awakens the peer-to-peer networking that is deeply behind the Internet. Napster's file sharing function is a common thing to share directory in LAN. But Napster's success has made people realize the possibility of extending this "peer-to-peer networking" to the whole Internet. Of course, in the eyes of many people, Napster is not pure P2P, it still needs a central coordination mechanism

in fact, many existing services on the network can be classified as P2P. Instant messaging systems such as ICQ, AOL Instant Messenger, Yahoo pager, MSN Messenger from Microsoft and OICQ in China are the most popular P2P applications. They allow users to communicate and exchange information and files with each other. The information exchange between users is not direct, it needs a server in the center to coordinate. However, these systems do not have such functions as search, which are very important for a large number of information sharing. The lack of this feature may be one of the reasons why instant messaging has appeared for a long time, but it has not been able to proce such an impact as Napster

another thing that can be classified as P2P is auction websites, such as eBay. When people summarize the mode of eBay, they use C2C. Is it a bit similar to P2P? EBay is a community that connects people and trades goods. Users can easily search for goods that other users sell. EBay offers some services to make the transaction go smoothly, but the transaction is directly between users. If the concept of "transaction" is extended, C2C is a special case of P2P, where people exchange goods with each other

but if we look into it carefully, Napster and instant messaging give users the ability to communicate directly and eBay allows users to trade directly. At the same time, they destroy the server-side idea of peer-to-peer networking, which has existed since the advent of the Internet, because they need a central server to coordinate, rather than distributed in different parts of the world Many servers in peer-to-peer networking. This is exactly what Gnutella and Freenet constantly claim that they have created "pure" P2P, without P2P service of central server at all.
