Dei decentralized financial lending

1. Defi, also known as open finance, refers to the financial application ecosystem created with the help of blockchain network (especially Ethereum)
users in the defi ecosystem have complete control over the assets and participate in the defi with the help of P2P network and DAPP
advantages of defi
the popularity of defi is inseparable from its unique advantages. Defi mainly includes:
1. Open loan agreement
compared with the traditional credit structure, open and decentralized loans have many advantages, including integration of digital asset lending, digital asset mortgage, real-time transaction settlement and novel secured loan methods, no credit check, standardization and interoperability. The purpose of secured lending using open protocols such as maker and Dharma is to rece the risk of counterparties without intermediation by relying on the minimum amount of collateral provided by Ethereum
2. Issuance platform and investment
famous securities issuance platforms such as polymath and harbor provide the framework, tools and resources for issuers to issue marked securities on the blockchain. They have prepared their own standardized token contracts for securities (i.e. st-20 and r-token), which are unique in terms of automatic compliance and customizable transaction parameters and can meet regulatory requirements. Similarly, they are integrated with service providers (e.g., broker dealers, custodians, legal entities, etc.) to assist issuers in issuing
3. Decentralized forecasting market
decentralized forecasting market is one of the most attractive components of open finance, which is highly complex but has great potential. August launched the anti censorship forecast market last year, and other platforms like gnosis began to follow suit. Forecasting market has long been a popular financial tool for avoiding risks and speculating on world events, and decentralized forecasting market can also do this
4 exchanges and open markets
exchanges in open finance mainly consider decentralized exchange (DEX) protocol and P2P market. First of all, DEX is a P2P asset exchange between two parties on Ethereum, in which no third party acts as an intermediary, such as coinbase or other centralized exchanges. DEX also uses some highly innovative methods to exchange tokens, such as atomic exchange and other unmanaged methods, to exchange one asset for another with minimal settlement time or risk. The most popular DAPP in Ethereum is the decentralized exchange IDEX. Although many "DEX" claim that they are indeed decentralized or unmanaged, be careful before using them. The P2P market on Ethereum has great long-term potential, and may eventually cover the market of local digital assets and marked real-world assets
5. Stable currency
stable currency is booming in the digital asset market by issuing warrants, auditing its reserves and managing its price linked new model. Stable currency is just a token issued by the blockchain, which aims to keep a stable link with external assets (mainly US dollars, gold or other assets). The stable currency of encrypted mortgage includes Maker & # 39; S Dai, where the underlying asset (e.g., ETH) is over mortgaged relative to the borrowing asset (DAI) according to the current mortgage rate. So far, stable currencies backed by legal tender are the most popular because of regulatory compliance and no audit risk, such as tether, usdc and Gemini dollars
disadvantages of defi
on the one hand, the development of defi is restricted by the performance of the underlying public chain. The current defi project is mainly built on the Ethereum network. At present, the performance bottleneck of Ethereum is relatively prominent, and there is still a long way to go to break through the bottleneck. Under such a situation, those projects with high performance requirements will be in an embarrassing situation. On the other hand, compared with traditional financial procts, decentralized financial projects are much more difficult to use and have higher cognitive requirements for users, which will also greatly affect the development speed of defi. In addition, the roller coaster like ups and downs of defi projects (sushi, yam, yfii, etc.) also make people wary of its security. How to continuously accumulate user trust is also the focus of attention in the future.

2. 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
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%<

3. 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<

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!

With the expansion of the imagination boundary of the combination of blockchain technology and finance, the emergence of decentralized Finance (referred to as "defi") may bring some enlightenment. According to the latest data of the graph, a blockchain data index company, the number of defi monthly queries exceeded 1 billion in June. In the previous few months, the daily query volume of the graph hosting service was 20 million to 30 million, but in June, the daily query volume reached 40 million to 60 million
according to the report of dapppreview, the information and analysis platform of dapps based on blockchain, in the second quarter of 2020, the total transaction volume of Ethereum profi increased by 403% compared with the same period last year, and the market value of several Ethereum profi projects more than doubled in the second quarter. Under the frenzied pursuit of capital, it needs cold thinking to treat defi
defi
defi is still in its infancy, facing three major challenges:
first of all, code loopholes. Programmable finance represents the power of science and technology, but the loopholes after code stacking are always difficult to avoid
the second is the systemic risk. Whether it is traditional finance or programmable finance, we must consider the systemic risk, such as whether the defi ecosystem can carry it in the face of extreme market fluctuations
the third is the asset on the chain. The complexity and uncertainty of the asset on the chain is a great challenge for the whole defi instry, which needs to be tried by the pioneers
the defi application faces the risk of hacker attack. According to media reports, only from February to march in 2020, there were six security incidents in the field of defi, with a loss of more than $1.5 million

7. India bit focuses on the official quality maintenance. At present, it has won the official authorization of Shenma and Xindong. Avalon and yibit are also applying for the official authorization. They have five years of ant mining machine maintenance experience. Their team has more than 40 licensed maintenance engineers who have received the official training of mining companies. This kind of strength is very competitive in the mining instry, and the materials used for maintenance are all original materials, It will greatly rece the secondary failure rate.
8. 1、 What is defi
defi is decentralized finance. With the rapid development of blockchain, its application scenarios are constantly enriched, and the financial instry is one of the most promising instries. At present, defi is mainly active in the Ethereum network ecosystem. After two or three years of exploration and development, it has derived a variety of financial innovation methods, such as stable currency, lending platform, derivatives, forecast market, insurance, payment platform, etc
in short, defi is to move the traditional finance to the blockchain network, but compared with the traditional finance, it realizes decentralization through the blockchain, that is, it removes the role of middleman, thus recing the huge cost brought by the intermediate link
the ultimate goal of defi is to realize asset securitization, using smart contracts to replace the traditional privileged institutions in the financial field, so that users can enjoy financial services at a lower cost, improve the operation efficiency of the whole financial system, and rece the operation cost< 1. Maker
there is no doubt that maker is the leader in the field of defi, and what is maker to defi is just like bitcontinent to the mining circle. According to the data of defi pulse, the total market value of defi lock has reached 957.5 million US dollars, and maker accounts for 544.7 million US dollars, accounting for 56.89%< Established in 2014, maker is an automated mortgage platform on Ethereum and a provider of stable currency Dai
Dai and the US dollar are anchored 1:1. Like other stable currencies, Dai also has price fluctuations. Unlike other stable currencies, Dai gains value by over mortgaging encrypted digital currencies. For centralized stable currencies such as usdt, trueusd and GUSD, there is a reserve of $1 behind every $1 token issued, while the reserve of $1 Dai is a reserve of more than $1 digital assets
unlike usdt and trueusd, Dai's operating mechanism is open and transparent, which is one of Dai's advantages. Not only Dai itself is transparent, but also the value fluctuation and quantity of Ethereum, the collateral in exchange for Dai, are also transparent and visible to the public.

Maker
there is no doubt that maker is the leader in the field of defi, and what is maker to defi is just like bitcontinent to the mining circle.

Dai and the US dollar are anchored 1:1. Like other stable currencies, Dai also has price fluctuations. Unlike other stable currencies, Dai gains value by over mortgaging encrypted digital currencies. For centralized stable currencies such as usdt, trueusd and GUSD, there is a reserve of $1 behind every $1 token issued, while the reserve of $1 Dai is a reserve of more than $1 digital assets
