1. 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.

2. 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<
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.

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!

4. What I trust more is the coin letter wallet. Since 17 years ago, I have been trading bitcoin on it. Risk control has done very well and never had any problems. Moreover, there are many kinds of digital currencies available on it.
5. Different from the general forward transaction, NDF is that the customer and the bank agree on the forward exchange rate and transaction amount, and settle the difference between the previously agreed exchange rate and the spot market exchange rate on a specified date in the future, without the need to deliver the principal. It is a financial means derived by international trade enterprises to avoid exchange rate risk for countries or regions with foreign exchange control
the market turnover of NDF is more than US $10 million, generally about US $50 million, and less than US $100 million; The margin is about 10% of the contract amount. The core concept of the financial derivatives is that the two sides of the transaction have different expectations for the future trend of a certain exchange rate, which can only be undertaken by overseas banks
corresponding to this is the domestic forward foreign exchange settlement and sales, also known as DF (foreign exchange forward contract) by the instry. The online publicity materials of Bank of China describe forward foreign exchange settlement and sale as follows: financial procts that lock in the current foreign exchange cost and keep the value and avoid risks for enterprises. The specific method is that the customer and the bank sign a forward agreement on settlement and sale of foreign exchange, and agree on the currency, amount, term and exchange rate of the future settlement of foreign exchange (the enterprise sells foreign exchange to the bank) or sale of foreign exchange (the bank sells foreign exchange to the enterprise)
the difference between NDF and DF is that the former is a long-distance exchange contract without principal, while the latter needs spot delivery after maturity.

6. 1. ADF is the present value coefficient of annuity, which is the value converted from one yuan received and paid in each period according to the interest rate. That is to say, knowing the present value coefficient, we can get the sum of the present value of a certain amount of annuity
2. DF is the present value coefficient of compound interest. It is the symmetrical concept of compound interest terminal value, which refers to the present value of a specific fund at a certain time in the future calculated by compound interest, or the principal and interest required to obtain a certain compound interest present value coefficient in the future.

9. As a wholly-owned subsidiary of China UnionPay, a classmate of mine works there. The welfare is quite good. It's more humanized, the work pressure is relatively low, and the recruitment requirements are very high. The company, from the company's boss to ordinary employees, is a contract system. Only non core positions are dispatched. The recruitment requirements are relatively low, but there are also many benefits. What kind of contract you sign depends on your strength and the position you apply for. However, compared with other companies, the salary is pretty good.
