clear top jewelry boxes wholesale Blockchain --- distributed finance (DEFI)

jewelry bulk wholesale Defi is an abbreviation of the term Finance (distributed finance), usually refers to the digital assets and financial intelligent contracts, protocols and distributed applications (DAPPS) based on Ethereum.
It simply speaking, DEFI is to move traditional finance into the blockchain network, but compared to traditional finance, it realizes decentralization through the blockchain, that is, remove the role of the middleman, thereby reducing the middle in the middle The huge cost brought by the link.
DEFI to finally realize assets token, replace traditional centralized financial institutions with smart contracts, enjoy financial services at lower costs, and improve the operating efficiency of the entire financial system, reduce Operating costs. At the same time, build a global open -minded financial system to create an open, transparent, and secure new decentralized system, so that everyone can freely trade.

With the rapid development of the blockchain, the application scenarios of DEFI are also continuously enriched, and the financial industry is the most promising industry.

is similar to the bank. Users can save money and get interest from other users who borrow their assets. However, in this case, the assets are numbers. Smart contracts associate the lenders with the borrower, execute the loan terms and allocate interest. All this happened, and there is no need to trust each other or the middle bank. Moreover, due to the transparency provided by the blockchain, by reducing the middlemen, the lenders can earn higher returns and understand the risks more clearly.

The decentralized exchange, referred to as DEX, DEX is a cryptocurrency exchange that uses smart contracts to execute trading rules, execute transactions and handle funds securely when necessary. When using DEX for transactions, there is no centralized exchange operator, no registration, no identity verification or withdrawal fee.

DEX can be traded with thin order. For example, you need to use 10 A to change 15 B, then I write it down. Then there was another person who said that I wanted to use 15 B to change 10 A. I said it was great, and it was exactly pairing. So, I generated a transaction on the chain to exchange each other's currency. At this time, the exchange rate is actually used for the two parties of the transaction -it is recommended that you use this exchange rate to find a pairing. In this way, the decentralized exchange only matches the needs of both parties to put on the chain, and there is no problem with smart contracts to read chain foreign exchange rate information.
This there are many defects. No matter how friendly this DEX is doing, it must be very poor compared to the centralized exchange. First of all, it is difficult to find matching when the currency price fluctuates. Small. But compared to the central exchange, it still has the only advantage -reliable.

DEX can also use AMM (automatic city merchants) transactions, that is, calculate the exchange rate based on your own supply and demand relationship to ensure that the coins in your hands will not be bought short at low prices. The easiest way is to always ensure that the number of A coins and B coins is a fixed value, so that even if it sells short, the loss is limited, and the market will always adjust the price to the right level -because if the exchange rate is low anyway, if the exchange rate is low, Someone will buy it, and someone will sell when the exchange rate is high.
In this simple method, a market that can automatically adjust according to the supply and demand relationship without obtaining exchange rate information from outside the chain. Of course, the weakness of this thing is also obvious -if the exchange rate at the beginning is not near the market exchange rate, it will bear a lot of losses. And there are "free losses" in AMM.

The stable currency is a tokens that are aimed at maintaining specific values, and are usually linked to legal currencies such as the US dollar.
For example, DAI is a stable coin linked to the US dollar and mortgaged the Ethereum (ETH) chain. Its issuance is achieved through a loan smart contract: everyone can use a certain number of ETH (Ethereum) to exchange the 1: 1 anchor DAI by mortgaging a certain amount of ETH (Ethereum). Here, DAI uses an excess mortgage form. For each DAI, it locks $ 1.50 in the MakerDao smart contract as a mortgage.
It if you mortgage to $ 150, then you can only get DAI worth $ 100. Then, this smart contract was written that if you return the $ 100 DAI and pay a part of the interest within a certain time, then you can take it back to the Ethereum you mortgaged.
but there is a problem here -the price of Ethereum will change. Moreover, the price change of virtual currencies is quite violent. What if the Ethereum plummeted when it encounters Ethereum? Then the original value of $ 150 may be less than $ 100 in an instant. At this time, the mortgage assets are not as more as the assets I have loaded, and the price of DAI can no longer anchor the US dollar because everyone can see: DAI does not not see: DAI does not do not. It's worth so much money.
Os how to solve this problem? The role of over -mortgaging is revealed -even if the price fluctuations in Ethereum are large, it will take some time to fall from $ 150 to $ 100. And this is room for asset liquidation: First of all, we stipulate that the mortgage must not be less than 150%of the loan, that is, if Ethereum rises, it does not matter, but once it falls, you have to make up the position to 150%immediately, otherwise your mortgage will be your mortgage. Smart contracts that will enter the liquidation.

The virtual assets used to install DEFI can be used for transfer.

A asset management tools (also known as the view board) are specially provided wallet scanning services. You can view the details of the wallet and historical records.
The most important asset management tools are Debank, Zerion, and Zapper.

In general, there will be many opportunities for mining in the market, which is also the opportunity for everyone to make money. At this time, there are asset management or financial services that provide financial services that provide financial services and say that I will help you make money business. As long as you give me money, I will go to the market to find a chance to make money. Help you make money.
YFi is the most important financial management tool.

The robots of the blockchain world are decentralized, that is, it is not clear who belongs to. In this case, if the robot fails, who should we look for? What should I do? Who is responsible for losses? In this case, the insurance robot is needed. It is specifically insured for other robots.

The robots of the blockchain world are decentralized, and are open and transparent, and automatically execute. What should these robots be upgraded and maintained? How to ensure the decentralization of the robot?
Generally, many people negotiate around the same robot and vote to decide how to let the robot upgrade and provide services. The DAO robot is a robot that helps these people to form a decentralized governance relationship with the robot.

The robot specifically provided asset prices. For example, when the small C robot just given an example receives a bitcoin, it needs to know how much a bitcoin is worth it. Otherwise, there is no way to calculate how much it should be loaned to Xiaoming. At this time, it is predicted that the machine robot will go to Xiao C, enter a price, and tell the Little C robot that Bitcoin is now worth $ 10,000.

Ethereum is a blockchain network that maintains digital value sharing. The person replaced the central power agency and controlled the distribution of local cryptocurrency Ether (ETH) in a decentralized manner.

DEFI ranking published by DEFIPULSE, which tracks the real -time value in the global DEFI smart contract.
MakerDao is an undoubted leader in the field of DEFI. MakerDao is like a mining circle of Bitmain.
MakerDao was established in 2014. It is an automated mortgage loan platform on Ethereum and a provider of stablecoin DAI. MakerDao is a decentralized financial system built on Ethereum. It uses a dual currency model, one is stable currency DAI, and the other is equity tokens and management tokens MKR. DAI was online in December 2017. Through the dual currency mechanism, MakerDao enables the entire decentralized pledge loan system to operate.
DAI and the US dollar are anchored 1: 1. Like other stablecoins, DAI also has price fluctuations. Unlike other stable currency, DAI is valuable through over -mortgaged encrypted digital currencies. The centralized stable coins such as USDT, TrueUSD and GUSD have $ 1 fiat currency behind $ 1 to the tokens of each US dollar as a reserve, and behind the 1 DAI is a digital assets exceeding 1 US dollars as a reserve.
. Different from USDT, TrueUSD, etc., the operating mechanism of DAI is open and transparent, which is one of the advantages of DAI. Not only is the DAI itself transparent, but the value fluctuations and quantities of DAI's mortgage Ethereum are also transparent, and it is publicly visible to the outside world.

ComPound protocols create an intermediary loan platform. (First-class notes: Usually we deposit tokens into the borrowing pool as the debit, and the party of the tokens from the borrowing pool is the loan party.)
Compound's new ERC-20 tokens referred to as CTOKEN, the user is used by the household It can be easier to perform loan operations. For example, supporting CDAI exchange with DAI, DAI holders can lend tokens to CDAI users. Not all wallets support exchanges, but in the Eidoo wallet, users can easily exchange DAI with CDAI to borrow DAI for interest. Today, Compound supports a total of 8 CTOKEN, which locks up to about $ 200 million in assets: CDAI, CETH, CUSDC, CBAT, CWBTC, CSAI, CREP, CZRX.
The debit can withdraw token from Compound at any time, automatically and instantaneous calculation of interest. If it is through non -hosting wallets like Eidoo, no intermediary (because Ethereum's decentralized agreement can be done).
The loan party must lock the tokens as mortgages, and obtain 50-75%credit according to the strong and weakness of basic assets.
Compound protocols also have 10%interest as the reserve, and the remaining 90%interest is attributed to the borrower. No cost, no protocol tokens. Based on Ethereum's credit market, a real decentralized flow pool is formed, which is issued and obtained in a non -agency, autonomous, and fast way.
Synthetix is ​​based on Ethereum's synthetic asset issuance protocol. Synthetix currently supports issuance assets including fiat currency, cryptocurrency, and commodities. Among them, the fiat currency mainly includes USD (SUSD), the euro (SEUR), and the yen (SJPY), but it is basically SUSD. There are Bitcoin (SBTC) and Ethereum (SETH) in cryptocurrencies. In addition, there are reverse cryptocrete assets, such as IBTC. When the price of BTC fell, IBTC prices rose, thereby profitable. In terms of commodities, it is currently dominated by SXAU and SXAG.
The transaction on Synthetix is ​​performed by decentralized mode, and there is no need to transaction to the existence of the opponent, nor do they have to worry about liquidity and slide points. The transactions on its exchange are executed through smart contracts, and transactions to smart contracts, not order book transactions. These have its unique trading experience and some advantages.
Synthetix Like other asset issuance agreements, asset mortgage is required to issue it. For example, the MakerDao protocol needs to generate DAI and needs to mortgage ETH. Synthetix is ​​similar, but it mortgage its native currency SNX. As long as the user locks a certain amount of SNX in its smart contract, synthetic assets can be issued. Among them, its pledge rate is very high, which is 750%of its issuance assets. Only when the target values ​​reach 750%have the opportunity to get a reward for transaction fees and SNX new token.

tvl is the total value of the locking of each DEFI protocol. The higher the better.
dex is the transaction volume, the higher the better.
The number of active addresses represents the number of DEFI users on Ethereum, the more the better.
The lower the handling fee, the better.
Itta as an infrastructure, its market value can be very high. However, when it comes to the proportion of the market value of DEFI, the market value of Ethereum should be lower the better, and the higher the market, the more mature this market.
