Decentralized loan aggregator
De flow means that all social resources can be aggregated and distributed with one click
in a system with many nodes, each node has a high degree of autonomy. Nodes can connect with each other freely to form a new connection unit. Any node may become the stage center, but it does not have the mandatory central control function. The influence between nodes will form a nonlinear causal relationship through the network
This kind of open, flat and equal system phenomenon or structure is called decentralization
extended materials:
compared with the previous Internet (WEB 1.0) era, today's Internet (Web 2.0) content is no longer proced by professional websites or specific groups, but by the participation of the whole Internet users and the creation of equal power levels. Anyone can express their views on the Internet or create original content to proce information together
with the diversification of network service shape, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together
1. Enjin (enj)
in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers
Cardano (ADA)compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:
scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol
interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol
Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform
With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projectsNash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here
4. Basic attention token (BAT)
bat mainly solves the problem of advertising:
user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users
the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake
in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast
5, chainlink (link)
chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract
companies including Google are supporting the development of chainlink. Here is a list of chainlink partners
one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present
Ethereum (ETH)Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run
(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%<

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
both sides mainly refer to the lender and the borrower, so they are called both sides
the borrower refers to the borrower, and the loan refers to the borrower
decentralized lending refers to matching the borrower and the lender through the past central lending agreement, and then transferring the assets and completing the lending immediately after the confirmation of mortgage and pledge
the decentralized lending protocol provides the platform with the technical basis of standardization and interoperability, and plays the role of security management in the lending process. Compared with the traditional lending model, the decentralized lending model has the following characteristics:
a. the combination of legal currency loan and digital asset loan (stable currency model can be regarded as the combination of legal currency and digital asset)
B. mortgage based on digital assets
C. realize real-time transaction settlement through automation, and rece the actual cost
D. replacing credit review with over mortgage mode also means that it can serve more people who can not use traditional services<
