Which layer of blockchain does defi belong to

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. 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.

3. 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.

Defi is the abbreviation of decentralized finance, which refers to rebuilding the ecosystem of protocols, platforms, applications and tools of traditional financial procts outside the traditional financial system

the defi solution is not provided by banks, but is built using open source software and non censored networks. As a result, the defi proct is essentially transparent and open to anyone who can connect to the Internet. Defi procts enable the world to participate in financial activities (such as consumption, borrowing, lending, gambling and trading) in a point-to-point manner without relying on intermediaries such as banks and governments

< H2 > extended data

the value of growth in the field of defi is more than 675 million US dollars, which is locked in the defi agreement. In the past 12 months, many people have been closely following the development of this field. Defi is becoming a parallel financial system with the traditional central bank, Santander bank, Deutsche Bank and pension funds

almost all the defi solutions are built on Ethereum, which is an open blockchain platform and the best in terms of development and active users

the defi solution is supported by blockchain technology, using the most powerful features of the technology: programmable digital assets, such as bitcoin (BTC) and Ethereum (ETH). These digital assets have monetary value, mainly because of the value storage characteristics. Because these assets are programmable, we can lock them into smart contracts as collateral (similar to home mortgages)

5. Defi is short for decentralized finance, also known as open finance. It actually refers to the decentralization protocol used to build an open financial system, which aims to enable anyone in the world to carry out financial activities anytime and anywhere
in the existing financial system, financial services are mainly controlled and regulated by the central system, whether it is the most basic deposit and transfer, or loan or derivative transactions. Defi hopes to establish a set of transparent, accessible and inclusive peer-to-peer financial system through distributed open source protocol, so as to minimize the trust risk and make it easier for participants to obtain financing<

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.

6. 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.

7. Pishon is OK. PIs miners enlarge their computing power by pledging pusd, which drives miners to participate in the initial asset synthesis of pusd

2. Digital electronic control fuel injection is an advanced fuel injection device for gasoline engine without carburetor, which popularizes electronic control gasoline injection technology from gasoline engine, and improves the atomization of liquid fuel in the process of gasoline engine mixture formation, More importantly, the fuel injection quantity can be accurately controlled according to the change of working conditions, so that the combustion will be more sufficient, so as to improve the power, rece the fuel consumption, and meet the requirements of emission regulations

The fuel system is mainly composed of fuel tank, fuel pump, fuel filter, pressure regulator and fuel injector

function: to supply a certain pressure of fuel to the injector, and the injector injects fuel according to the computer instruction

principle: the electric fuel pump sucks gasoline from the fuel tank, filters it through the filter, adjusts the pressure by the pressure regulator, and delivers it to the fuel injector through the oil pipe, which injects fuel to the intake pipe according to the computer instructions. The excess gasoline supplied by the fuel pump flows back to the fuel tank through the return pipe
