Defi picture of decentralized Finance

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. Defi, a decentralized trading platform, is more reliable. I think it's a professional platform. It's a better platform because it has a wide range of radiation

3. 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

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< br />

6. First, because the power consumption of mining machinery is amazing 2150 watts, the household electricity consumption is about 50 cents per hour, and the cost is relatively high, while in the mine trusteeship, the cost of electricity is relatively low, which is more than 20 cents<

secondly, the noise of bitcoin miner is very loud, with 90 decibels. A single miner can kill a family. If you play at home, unless you do sound insulation treatment

thirdly, the use of bitcoin mining machine needs to connect the ore pool to set up, etc., and it must have some professional operation knowledge, which is difficult for ordinary people to learn

Fourth, the running status of bitcoin miner needs to be monitored and monitored for 24 hours

fifthly, bitcoin miner will generate a lot of heat in the process of operation, so it is not cost-effective to use air conditioning at home

sixth, cluster mining, single miner output will be higher!

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. The total circulation of qubu candy is 1 billion, and it will never be added. It can be said that every candy is worth cherishing. In the future, with the graal development and being known by the public, the value of candy will soar. Please save it
if it goes up to a few, it's worth it.

9. Foreword: ring my internship, I have deep experience. In the past, I really thought that what I did was enough to be worthy of my own salary, because I was not the only one in the company. Although I was also working hard, the purpose was: if I did more, I would be affirmed by the master or the boss. Now, I feel that all the work I do in the air conditioning company is actually paving the way for my future. Because in air conditioning, I can learn a lot from the people around me to learn their strengths and make up for their weaknesses. There must be a teacher for three people. Choose the good and follow it, and change the bad, so that I can improve myself, look up, step by step, and do better! Only with an open mind can we empty out the bad and receive the good. In the past few months, I have learned what is the spirit of work, which is the inner meaning, not the eight words on my lips. I also try to take these eight words as the criteria of my life, and go to perfection step by step

1. Honesty is honesty, not to do false things, the purpose is to get the recognition of others. In business, we should also be honest. In this business field full of deceit and deception, it is very difficult to make people believe. Maybe sometimes, they will lose their own interests, but over time, honesty will become the best rock for us to stand in the society. It will also give our opponents effective lethality, or a fatal blow; In my opinion, it's a long and cumbersome process to believe that the air-conditioning company has guarantee in equipment, and the customers believe that our company's things are good. But once we do well and we go out, the evaluation of others will surpass that of all peers. This is to strive for the first place in the same instry

2. Dedication is also a psychological problem. A person who takes work as a pleasure must be dedicated. For example, if you like to play games, you will stay up all night and forget to eat and sleep. If you like to work, there will be no difference between weekends and working days, and your attitude towards customers will change greatly. For example, if the air-conditioning engineering department is dedicated, it will clear the relevant information of customers in detail, analyze customers, visit customers frequently, understand their views on us, and explain the details of installation and maintenance of air-conditioning to customers in detail, so as to improve continuously, so as to do better. If the air-conditioning engineering department is dedicated, it will maintain the equipment very well.... We will treat the requirements and attitude of customers positively and correctly, and we will surpass ourselves when we are dedicated. We will meet the differentiated needs of customers with standardized services, and be a little better than others every time, so as to strive to be the first in the same instry

3. One person in a team can't accomplish a big mission, and team is the best way to learn from each other. Not only can private enterprises grow rapidly, but also team members can learn a lot from each other, making the team more inseparable. (Rooster and termite, one will be eaten by rooster, many will be eaten by rooster, the law of nature is not the law of society.) although there are many problems in the team, as long as there is team spirit here, Everything will be solved. Once we cooperate with each other, the attack from outside will be useless. So as to naturally achieve the purpose of creating the same instry excellent

4. Innovation without innovation, we will stand still. The above three prerequisites are needed. Without honesty, he will not think of innovation (some innovations may be the meaning of customers); Without dedication, he is lazy to innovate; Without a team, perhaps his innovation is just a small discovery, which can not be more perfect. The team will make innovation more blameless. Only by continuous innovation can indivials succeed and private enterprises become brilliant. Naturally become the first in the same instry

the above is what I realized in this year, and what I should learn and apply in the future. No matter where I go, it's my homework. Also hope our team can do supervision work, so that I can do better
