Dai decentralization
(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
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%<

what is stable currency
stable currency, as its name suggests, is a cryptocurrency with stable value, and its exchange ratio with legal currency remains relatively stable. Because the exchange ratio between legal currency and goods and services is relatively stable, the ultimate anchor of stable currency is goods and services, that is, the actual purchasing power
stable currency originated from usdt (benchmarked US dollar) issued by 2014 bitfinex established tether limited. The opportunity for the birth of cryptocurrency is that the mainstream currency accounts for the vast majority of the market value, but the price fluctuates violently, which makes the liquidity of cryptocurrency market decline. In this case, in order to protect their assets, investors need to find a better way to store value, so the stable currency market arises at the historic moment
the essence of stable currency is a kind of accounting voucher
modern banking system is based on the central bank at the bottom, commercial banks at the top and financial technology companies at the top. Their basic prototype mainly comes from the double entry bookkeeping which was born 500 years ago. Even after so many years, the banking system is constantly developing and changing, but its core is the centralized account system, which depends on the central bank. When we transfer money from one account to another, we are actually making account changes through the bank. When using stable currency for transfer and remittance, it completely transfers from its own account book to another account book. The essence of stable currency is a kind of bookkeeping voucher
some people would say, isn't Alipay also using block chaining technology? On this basis, Alipay upgraded and upgraded the account book, which is two different schemes based on the stable currency issued by block chain technology. You see that money is transferred from a Alipay account to another Alipay account, but it is still operated in the central bank's account system.
why is stable currency the future of blockchain
at present, stable currency is mainly used to provide channels for legal currency to enter the cryptocurrency world, help currency people avoid risks in transactions, and provide payment services for blockchain application projects. Although the current digital currency market is not too optimistic, but the cryptocurrency project is in constant development. The number of stable currencies on the market has already exceeded 50, and is still on the rise. 2019 is bound to be the year of stable currency outbreak. How did stable currency break through in the wave of digital currency? Why is stable currency the future of blockchain? This involves how stable currency affects the blockchain instry
tickets for users to enter the market
after "94" in 2017, China banned the market circulation of cryptocurrency, restricted banks and other financial institutions as payment platforms or channels, and many countries also restricted the circulation of cryptocurrency. But there are still a lot of users who want to enter the market, they will choose over-the-counter trading and trade through the community. But because of the uncertainty, opacity, small scale and other problems, OTC has some trading risks. Usdt, a stable currency anchored to the US dollar at a ratio of 1:1, has become a supplementary scheme for some new funds
the insurance medium of user assets
in the weak market, the price of token fluctuates greatly, and traders do not want to take risks or leave the market. In the case that the trading platform does not support legal currency trading pairs, it is almost the only choice to use "stable currency trading pairs" to exchange for stable currency
the emergence of stable currency is the proct of a special historical stage e to the contradiction between the rapidly developing demand for token investment and the restriction of legal currency admission by regulation. The more serious the price fluctuation of mainstream currency is, the more valuable the existence of stable currency is
"trade as settlement" is an efficient payment and settlement tool
blockchain technology has great value in the field of payment and settlement. With the emergence of JPMorgan JMP, many banks around the world have begun to explore how to use blockchain technology to issue stable currency. The "stable currency" issued by these banking giants is essentially using a convenient and efficient settlement network based on blockchain technology. The more financial institutions and customer groups join the network, the greater the value of the settlement network
as JPMorgan Chase, IBM and Facebook have revealed that they want to issue currency, stable currency has once again set off an upsurge. After the strong fluctuation of usdt in the second half of 2018, it was derided as "unstable stable currency" by many people, so Pax, tusd, GUSD, etc. followed closely. Seizing the market quota of stable currency is very fierce for a time, but the fierce market competition means that there is not much space left in the market, and no matter how much stable currency there is, it seems meaningless. Then the major exchanges began to launch their own platform currency. JPMorgan Chase, IBM and Facebook also entered the market. The situation of stable currency also changed greatly. Facebook and JPMorgan have both broad user base and far-reaching economic impact, and issuing currency will certainly have inherent advantages. Beijing Digital capital technology, which is deeply engaged in the study of the significance of stable currency, has made practical application of stable currency in postal, supply chain finance, lottery and other fields. It is understood that the world's first African blockchain lottery will also be released in the near future. In this way, we can certainly expect to stabilize the currency market.
Ethereum ushered in 2019 with a price of $130 and ended 2019 with a price of $130. In this year, Ethereum has gone through ups and downs, but in the end, it has returned to its starting point
(the price trend of bitcoin in 2015)
in that year, bitcoin finally went out of the way near the end of the year, and for most of the year, it performed mediocre. Although it rose and fell, its price remained at the same level
so, will Ethereum go out of the 2016 bitcoin market in 2020
these two years are similar. They are both "halved" years, two years after the last high point, and also expected to walk out of the soaring market
besides, Ethereum has the same illusion as bitcoin in 2015. Just as bitcoin experienced the failure of payment demand in those years, the ic0 project on Ethereum became a burden ring the bear market, and the project parties could sell the ETH that got from ic0 without any worry
like Nakamoto's bitcoin, v-god's vision of network scalability has been stuck for years rather than months, but in other areas, they are becoming more and more attractive
first, the external is blockchain, and the internal is defi
blockchain rose in 2014, but it rose at a faster speed in 2016, which is also a major reason why bitcoin can take off in 2017
the launch of Ethereum may also drive bitcoin, because initially you need to buy BTC to get eth
However, because Ethereum is Turing complete, it does not need a new blockchain network to realize a new invention. On the contrary, anything that can be coded can be coded with eth, including some primitive but fully automated banks
for example, one case is the stable currency Dai issued by the decentralized bank maker, which provides a demand interest rate of 10 times that of the bank (generally speaking, the bank's demand interest rate is about 3%)
it can be said that traditional banks lack advantages in this respect, because they have costs such as offices, employees who want rich bonus, and so on, which are obviously paid by bank users. And all of these are replaced by extremely cheap code on Ethereum
at present, this invention is still very young and has great development space, and the concept of DEI (decentralized Finance) has been generally proved to be feasible
2. From defi to technological revolution
some smart contracts are very complex. For example, to create Dai contracts, you need to put into eth to manage collateral, hedge, arbitrage, and create code price management strategies. Basically, you need to be your own bank
but from the perspective of end users, you don't have to care so much. All you need to know is: is the contract hacked? If not, how long has it been running
this is not a perfect way to measure safety, but relatively speaking, it is an effective way to quantify risk with technical level. You don't have to worry about managing collateral, you just need to exchange eth for Dai to earn savings
suppose you have a deposit of $100000, you think the stock price may be too high, or you think the dollar will strengthen, or you just want to have some quick and convenient financial savings
the last way is to put it in the survival period of the bank, but if you do, you will lose money because of inflation, because the bank interest rate in many places is very low, and the interest on the current savings account is basically 0%
but if you put it in a decentralized banking system such as Dai, you can get 4% deposit interest. All people have to do is buy eth first and then switch to Dai
let's imagine that if more people do this, it will indirectly push up the price of Ethereum. Therefore, it is wise to keep a part of eth, not all of them become Dai. Through this example, you may be able to imagine the development direction of Ethereum in the future
3. Will eth rise in 2020
if you regard Ethereum as the gateway to the new field of defi, then its value may be underestimated at present
just as bull sentiment is high, it will be divorced from reality, so will bear. Bears can often give a lot of reasons for the decline, but at present, in addition to some common reasons, we still don't know what negative aspects Ethereum will have in the future
Yes, the upgrade is always delayed, because it's too complicated, or for other reasons, you're not even sure whether it will be released in the end
Yes, like bitcoin developers, Ethereum developers will become arrogant because of their poor communication skills and contempt for "investors". Some of them have even left, thus slowing down the progress
Ethereum lacks a clear monetary policy - that said, Ethereum aims to rece inflation to near zero
ic0 projects are sold and sold. Many projects are fruitless, and the progress is delayed again and again. It is not too much to say that they are semi decentralized
in the bear market of the past two years, these shortcomings have surfaced, and there are more than these, but in the end, Ethereum still has a price of $130
this may mean that all the negative factors have been digested, and the market still believes, or even stubbornly believes, that it is worth at least $130
if there is no further decline, it probably means that it must rise, because ring the bear market, many potential positive factors and upgrading development have been ignored
Although defi seems to be only a field, it can slowly and graally automate more financial services through a large number of applications, and ultimately promote the development of banks and other financial entities
in addition, the delay of upgrade has been reflected in the price, although it is not clear whether other established factors have also been reflected in the price
for example, does the market really believe that the inflation rate of Ethereum will drop to near zero or even negative
has the potential demand for interest through POS been reflected in the price of digital assets? Once POS exits the market, what will happen to the locked eth? What's the new plan to convert eth 1. X (the name of the existing Ethereum platform protocol upgrade set) into POS fragmentation mechanism
we can list a lot of problems, but you know, Ethereum was declared dead earlier last year, but it has come to this day
therefore, it still has the opportunity to rise again, because it has achieved many goals, and there are more goals to achieve. At the same time, it has created a lot of new ideas (such as defi), some of which have been implemented, and some of which have just started
as for valuation, if we only talk about one aspect, such as replacing some banking services, even if there is only 20% chance, even if only 1% market share, it is still a thing worth trillions
as Darwin once said, "the species that can survive in the end are not the strongest or the smartest, but the ones that can adapt to change best."
at present, the most popular bank is ICBC, which handles etc free of charge
at present, ICBC handles the preferential activities launched by etc.
1, and the toll is reced to 10% discount, which will last until the end of 2019, and then there will be a 9.5% discount
2, payment discount: when you shop on ICBC e-life platform, you can enjoy the great benefit of random rection
3, free equipment: one OBU on-board equipment free of charge
(1) strengthen organizational leadership. A leading group for deepening the reform of toll road system and canceling provincial boundary toll stations on expressways, led by the Ministry of transport and participated by the national development and Reform Commission, the Ministry of instry and information technology, the Ministry of public security, the Ministry of justice, the Ministry of finance, the Ministry of human resources and social security, the people's Bank of China, the state owned assets supervision and Administration Commission, and the China Banking and Insurance Regulatory Commission, will be set up to coordinate relevant worksummarize and analyze the work progress regularly, and report major problems to the State Council in time Under the leadership of the Ministry of transport, a leading group led by the provincial people's government and participated by relevant departments will be set up in all localities to simplify the infrastructure construction proceres and accelerate the project construction in accordance with the emergency engineering The provincial people's government is responsible for (2) refining the work plan. Adhere to the people-centered, more from the user's point of view, in-depth investigation and research, find out the basic situation, improve policies and measures. It is necessary to clarify the timetable and road map, consolidate responsibilities at all levels, actively and steadily promote various work, and ensure smooth and orderly local debt management Relevant departments of the State Council and provincial people's governments shall be responsible for it)
you can apply for free or pay 99 yuan for membership service through credit card
most of the bank's etc equipment is bound with the credit card. When handling the credit card, the bank will give the etc equipment free of charge. The application process is similar to that of the ordinary credit card, but the driver's license of the bound vehicle needs to be added and copied. After the application is successful, the bank will mail the credit card and etc equipment, and users can go to the designated outlets for installation. Etc card and customer credit card binding, automatic dection, no recharge. In addition, in terms of online acceptance, ICBC recently took the lead in supporting the whole process of online processing of national etc label application, card binding, inquiry and activation business
therefore, from the perspective of convenience, wechat etc is definitely the most convenient. You can apply directly through wechat app, and wechat etc devices will be sent to users by express delivery. Relatively speaking, the processing proceres of bank etc are relatively troublesome, so you have to go to the bank in person
although wechat is better in terms of convenience, some banks have lower prices in terms of equipment fees and tolls than wechat, while bank etc has more preferential activities! So I think bank etc will be more cost-effective
I hope it can help you, please accept it!
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.
bitcoin is the first currency to realize the concept of "secret currency". In 1998, Wei Dai first expounded the concept of "secret currency" in cypherpanks mailing list, that is, a new form of currency that uses cryptography principles to control the issuance and transaction of currency, rather than relying on the central management organization. In 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto left the project and did not disclose much about his identity. Since then, many developers have devoted themselves to bitcoin projects, and the bitcoin community has grown rapidly
Nakamoto's anonymous identity often leads to groundless worries, many of which are related to the misunderstanding of bitcoin's open source features. Bitcoin's protocol and software are published publicly. Any developer around the world can view its code or develop their own modified version of bitcoin software. Just like current developers, Nakamoto's influence is limited to the changes he makes that are adopted by others. Therefore, Nakamoto does not control bitcoin. So, today, the question of the identity of the inventor of bitcoin may be the same as that of the inventor of paper
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
bitcoin home also has more introctions. I suggest you take a look.
