Compound decentralized lending

1. Chongqing jinwowo: the decentralized trust mechanism means that first of all, blockchain projects need to complete the recognized accuracy of information records. In terms of pure digital business, the purpose and value of blockchain can be achieved by ensuring the recognized accuracy.

2. Centralized wallet, also known as off Chain Wallet, completely depends on the company and server running the wallet. bitcoin stored in the exchange is stored in the centralized wallet (off Chain Wallet). The private key is not owned by the user, but in the wallet project side of the centralized server hosting chain, the fund is usually entrusted to the server
private keys and assets are transferred to the wallet for centralized management. Users don't need to worry about the loss of the private key of this kind of wallet procts, resulting in the loss of funds; However, the capital risk will be more concentrated in the wallet project side and server side. When the centralized wallet is conquered by hackers, users will suffer unnecessary losses
decentralized wallets, commonly known as onchain wallets, have private keys maintained by users and assets stored in blockchains
decentralized wallets are often referred to as onchain wallets. The private key is handed over to the user. If the private key is lost, the wallet will not be able to help the user recover, and the funds will be lost forever. But the decentralized wallet is difficult to be attacked by hackers, and users don't have to worry about the self stealing of the wallet service provider
centralized wallets are where assets are stored, while decentralized wallets are where private keys are stored
except for the exchange, it is not recommended to use the centralized wallet, although losing the private key may help you find it. But there is always a risk that the company will run

a decentralized wallet is equivalent to a channel, a channel to control its own assets on the blockchain by mastering mnemonics. For a decentralized wallet, the most important thing is to protect the security of the [private key]

the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

3. 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 (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%<

4. The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized.

5. HNB community set up a GMH, the policy and decision were voted by decentralized participants, executed by smart contract, without human intervention. Major issues shall be discussed and voted by the general meeting of all community members. The full-time boards (development board, reserve board and arbitration board) authorized by GMH perform their respective ties. It effectively protects the rights and interests of all.

6. 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

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!

7. Of course, we have to take the initiative. If your processing plant has comprehensive technology, it will have enough confidence! Dare to do anything, if the lack of technology, it is estimated that they will be nervous when receiving it! Where to find customers? You should go to a slightly bigger company or a big company. Only a big company will have the need of outsourcing processing. If you can find a big country enterprise, you will be successful. I used to stay in a company, the boss just climbed up to a large state-owned enterprise, specialized in outsourcing processing for them, and the pile of goods was the same as the mountain. Just process the supplied materials and drawings. The benefits are very good. Double the size of the company in one or two years! Small companies rarely need outsourcing processing. Besides, even if there is supply, it is not stable! There is no time

8. I feel that
de averaging is for the covariance behind the aspect. After de averaging, the mean value of each dimension is zero, and the mean value in the covariance is zero, which is convenient to solve
specifically, suppose that matrix A is decentralized to get B, then the covariance of B is the transpose of B * B
