Decentralized financial Oracle project

1. 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<

2. 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!

4. The main incement of financial ecological theory is the deterioration of financial ecological environment and the imbalance of financial ecological system. If this state is not changed decisively, it will threaten the stability of the financial instry and cause huge losses to economic development
performance
there are still some problems and deficiencies in the theory and practice of financial ecology, mainly as follows:
① the concept and connotation of financial ecology are not well understood. The concept of financial ecology lost the direction of financial ecology theory and the accuracy of financial ecology practice, which made the macro sector unable to start and the micro sector at a loss< (2) the basic principles of financial ecology are unclear. Many people use financial ecology, financial environment, financial mechanism and financial laws in combination, which leads to unclear objectives and channels of financial ecology, and it is easy to become a hodgepodge
③ the working mechanism and mode of protecting the financial ecology are unclear, and there is no standard for evaluating the state of the financial ecology, which makes the basis for specific research and investigation unclear< (4) e to the lack of knowledge and understanding of the scientific and forward-looking nature of financial ecology, many people do not know enough about the significance of the theory and practice of financial ecology, and some even think it is a kind of hype and catching up with the trend. This paper analyzes these four aspects in order to promote the development and unification of financial ecological theory
research
financial ecology is a bionic concept, and it is difficult to find similar terms in economic dictionaries. In China, Dr. Zhou Xiaochuan (2004) first extended the concept of ecology to the field of finance, and emphasized the use of ecological methods to study financial development. Shanghai Securities News exclusively launched the core content of the general report "China's urban financial ecological environment assessment" - the analysis framework of urban financial ecology
generally speaking, ecological environment is mainly a biological concept, which refers to the whole composed of various ecosystems composed of biological communities and abiotic natural factors, and has indirect, potential and long-term impact on human survival and development
according to this expression, the ecology of general things includes the sum of various relationships within and between systems, and is a dynamic and systematic organic chain. If we regard finance as a subsystem of social economic system, then financial ecology is an ecological chain composed of financial subsystem and other related systems, which is closely related to the sustainable development of financial instry
just as the survival and development of any creature in nature are determined by its own conditions and external environment, financial institutions, as a member of the social and economic system, on the one hand, the realization of its survival and sustainable development depends on its own system construction and management level

5. There was a voice on the radio: please stand up for three minutes of silence to mourn the victims of the Sichuan earthquake. Time seems to flow back to that terrible time...
on the afternoon of May 12, 2008, when people are all immersed in the joy of work and study, who knows that a disaster is quietly brewing, At 14:28 a.m., a devastating disaster came down from the sky. The 8.0 magnitude earthquake in Wenchuan, Sichuan Province, devoured people's beautiful dreams. The earthquake destroyed people's homes and affected many provinces, cities and regions. All of a sudden, power was cut off, traffic was paralyzed, mountains collapsed and rivers flooded. People in the disaster area fell into deep water, This little-known place on the map, a place rarely talked about by people, became the focus of attention of people at home and abroad in an instant. At that time, people carried forward the spirit of love, extended a helping hand to the people in the disaster area, and made the country prosperous

6. There are calculation formulas, but in general, the vertical load is about half of the horizontal load, which is a little more than half. If you choose a simple model, you can calculate by half, and there will be no problem
guide rail is a groove or ridge made of metal or other materials, which can bear, fix, guide and rece the friction of mobile devices or equipment.

7. Normal use has never hurt the hard disk. Only abnormal use can hurt the hard disk. For example, when the hard disk is working, you touch it, knock it, move the chassis, plug and plug the data cable, etc

SSD will be much faster in running system or virtual machine, and it is not afraid to touch, and its performance will be much better

don't consider that reading and writing files will damage the hard disk. The hard disk is not used to read and write data. Why is it used

however, the hard disk has an average fault free service life, which refers to the natural loss of mechanical parts. Generally, you don't have to worry about this. As long as the power quality is good, the hard disk can run for 24 hours, 3 to 5 years, or even longer.

8. According to the acceleration a = △ V / △ t △ v = V △ θ< br />a=△v/△t=v△ θ/ △t=v ω ω= v/R
a=v^2/R= ω^ 2R
force F = ma = MV ^ 2 / r = m ω^ 2R
