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. Judging from the currency price and market value of BNB and eth, there is still some gap, but the gap is narrowing with naked eyes. The only sad thing is that after BNB rises, the handling charges become more expensive. I regret that I didn't stock more when BNB was cheap.
3. 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.

4. Xpot is a coin ring artifact jointly launched by win GC group of Thailand and pundix of Indonesia. Xpot is a powerful combination of xpot and ipchain. All applications of xpot are developed based on IP chain of intellectual property chain. It will open up the last kilometer of digital asset circulation. It is matched by a card similar to a bank card - xpass
5.
The total number of atomic coins issued was 100 billion, and the total number of atomic coins was 1; 10 mapping
token is a tool to measure the transmission and transformation of value. As the parties participating in the construction of the system, token is the qualification basis for the distribution of rights and interests. Atomic chain will issue endogenous currency, which we call ATOS. In the initial stage of the system, it will be released based on erc20. In the medium-term stage, the 1:1 smooth migration to the main network of the atomic chain. Erc20 is a standard protocol on Ethereum network. It uses the protocol interface to create a token, which is used as the basis of warrant and qualification of each role. ATOS is the basic circulation value of the whole ecosystem. Through ATOS, users can realize transaction, value transfer, enjoy value preservation and increase, and vote. Atos is also the basic reward condition for each role to participate in. Through the reward, the enthusiasm among the roles can be stimulated, and the virtuous cycle of the ecosystem can be promoted. In order to fight against inflation and maintain and increase the value of contracts, we will issue a fixed number of ATOS. Through ecological operation, ATOS will maintain a certain minimum value. We use push in the ecosystem to push the ecological event report according to a certain period< ATOS is divided into circulation pool and lock pool. Under the condition of constant total amount, the total amount of market circulation and lock pool will maintain a certain proportion, so as to achieve the balance point within the pool
6. First, because the power consumption of mining machinery is amazing 2150 watts, the household electricity consumption is about 50 cents per hour, and the cost is relatively high, while in the mine trusteeship, the cost of electricity is relatively low, which is more than 20 cents<
secondly, the noise of bitcoin miner is very loud, with 90 decibels. A single miner can kill a family. If you play at home, unless you do sound insulation treatment
thirdly, the use of bitcoin mining machine needs to connect the ore pool to set up, etc., and it must have some professional operation knowledge, which is difficult for ordinary people to learn
Fourth, the running status of bitcoin miner needs to be monitored and monitored for 24 hours
fifthly, bitcoin miner will generate a lot of heat in the process of operation, so it is not cost-effective to use air conditioning at home
sixth, cluster mining, single miner output will be higher!

7. 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.
