Decentralization of light assets
the first step is to register (open an account) and set the password. The second step is user authentication (KYC). The third step is to recharge. Here comes the key. The third step is the most important. Because you need to charge money to your address in the exchange before you can trade money in the exchange. The address of the exchange is actually a wallet address, but the ownership of the wallet is not the user, but the exchange, that is to say, the private key of the address, you don't have it!!! Do you understand the meaning
well, after recharging, the transaction is finished. The user submits the instruction (hanging order) to the server, and then the exchange will be responsible for matching the transaction, which is exactly the same as the stock. The last is cash withdrawal (withdrawal of currency). Users can send instructions to transfer the currency from the exchange address to their wallet address. The above is the trading mechanism of the centralized exchange. In these steps, all actions will have costs. No matter you recharge, trade or withdraw money, gas and handling charges can't escape
then let's look at the decentralized exchange. The trading mechanism is different from the centralized exchange. The first step is to register (open an account) and set the password. It doesn't make any difference. But then it's a little different. KYC is not used. But because there is a private key, the ownership of this address is completely controlled by the user. The second step is recharging. This is not very different from the centralized exchange. You still have to make your own gas
after recharging, we can also trade in the decentralized exchange. Users can also register orders, and exchanges will also be responsible for matching transactions, but the matching is done by smart contracts. Finally, cash withdrawal (withdrawal of currency) is initiated. After withdrawing currency, users can directly transfer the currency from the address of the exchange to their wallet address. This step is the same as that of the centralized exchange
the above is the trading mechanism of centralized and decentralized exchanges, and the difference between them is also obvious. Because all currencies in the central exchange are under its control, the trading efficiency is very high, and it is similar to the stock trading process, convenient and suitable for most users. Conversely, the risk lies in this. If the exchange itself loses its integrity or is attacked by hackers, the user's capital (currency) is not guaranteed
all the transaction processes of decentralized exchanges are completed by smart contracts, so the transaction efficiency is relatively low (TPS of blockchain technology has always been a soft rib), but relatively, the capital (currency) is completely in the hands of users, so the security is relatively high. In addition, there are also KYC, where KYC is needed for centralization, but not for decentralization, and the security of personal information is relatively high. Compared with the decentralized exchange, the advantages of the centralized exchange lie in the trading depth and the number of users, which are unmatched by the decentralized exchange
therefore, centralization and decentralization have their own advantages and disadvantages. It depends on the user's own choice. They like convenient, centralized, secure and decentralized.
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 where you can master mnemonics to control your assets on the blockchain. 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.
core wallet, which needs to synchronize all blockchain data and takes up a lot of memory, but it can be completely decentralized. Light wallet relies on other all nodes in bitcoin network, only synchronizes data related to itself, which can basically achieve decentralization. Centralized wallet does not rely on bitcoin network, all data are obtained from its own centralized server, but the transaction efficiency is very high, and it can be received in real time. The account you register in the transaction platform is the centralized wallet.
since 2013, many decentralized trading platforms have emerged. Different from the centralized trading platform, the decentralized trading platform does not need to register an account, and can participate in the transaction by using the personal digital asset account
secondly, every transaction of the decentralized trading platform is carried out through the blockchain, and it needs to wait for the confirmation of the blockchain before the transaction is successful. At the same time, the decentralized trading platform is not responsible for keeping users' assets and private key information. On the one hand, it avoids the moral hazard of the trading platform, on the other hand, it requires you to keep your private key well
e to the low liquidity and slow transaction processing of decentralized trading platforms, the total transaction volume only accounts for 0.03% of the global total transaction volume of digital assets. At present, the tokens of airswap, kyber, 0x and omisego can be traded on huobi.pro.
the third feature of blockchain assets is decentralized bookkeeping
the transfer you give to others will not be delayed for a few days because the bookkeeping agency is on holiday; Not because the bookkeeping institutions want to make profits, so they have to pay high fees; More will not be because of accounting institutions cheating, and suffer losses
because its bookkeeping is carried out by the whole network. The account book that you transfer to others will not be unified because of the loss of the account book data here or there, because the account book is jointly maintained by the whole network, and every node has a backup. If you transfer 0.5 coins to fire coin Niuniu, you two can look at the record data of the whole network together: whether it has arrived, several confirmed, etc., which is very transparent and fair.
(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%<

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<

With the rapid development of human society, many people find that decentralization is a trend and also represents a new proction relationship. This is a new kind of proction relationship that is suitable for the business or business logic based on the highly developed and market-oriented human society and economy, equality and mutual trust. Since the decentralized trust mechanism blockchain has been established, many intermediaries will also face upgrading and innovation. For example, "Wall Street", a traditional medium which is essentially a financial intermediary, may soon develop into a new model
decentralization has changed more than one financial instry. In the consensus of China's excellent Internet company "Xunlei", science and technology is developing from centralization to decentralization. They are proud that their first P2SP download technology is a kind of decentralized technology. At that time, blockchain was not widely recognized. Xunlei believes that decentralized technology has many advantages. Its solution is light weight and low cost; It respects privacy and doesn't have an intermediate database to know everything; It accords with the development of society; It is a measure of environmental protection and sharing. In 2014, Xunlei made up its mind to do decentralized cloud computing, also known as shared computing, which is to distribute the computing needs to thousands of households and use the idle resources of users
such an attempt has got a very good market response, because the marginal cost of shared computing is lower than that of cloud computing, which can more effectively solve the social contradiction between the shortage of social computing resources and the high cost of computing, and rece the operating costs of enterprises, including Xiaomi, Aiqi and Xiongmao live broadcasting, which have become the customers of thunderbolt shared computing. In fact, the demand for computing in the current society is growing explosively. Whether it is artificial intelligence, big data, 4K, VR, the demand for network is higher and higher, the speed of computing is higher and higher, and the demand for speed is higher and higher. If you want to solve all the needs, you need to prepare sufficient computing resources. The player reward scheme is born to solve this problem
the significance of the player reward program is that in the shared computing ecosystem, Xunlei has joined the blockchain technology to share the bandwidth with the players through the cloud intelligent hardware Users of idle resources such as storage and computing power will issue the digital asset chain gram (original gamer coin) based on blockchain technology. Users participate in this plan for free, and they also voluntarily contribute idle computing resources to the society. Users actively contribute idle resources, Xunlei payment chain rewards users, Xunlei then packages and sells resources to enterprises, and a supply chain based on shared computing is completed. In this process, decentralized blockchain technology plays an important role
of course, complete decentralization lacks supervision, and there is a certain risk of being used. Therefore, the blockchain chosen by chaink is "alliance chain", not a completely decentralized public chain like bitcoin and Ethereum. Therefore, Xunlei still has the right of supervision. In order to rece and avoid the occurrence of malicious events of accounting nodes, and to ensure that users' transactions enter the block as soon as possible, Xunlei is more cautious in selecting accounting nodes. In the initial stage, Xunlei will choose its own servers with good network connectivity and stability, as well as its partners' servers with good network connectivity and stability, After the performance and security of the next generation of gamer cloud hardware are further improved, the gamer cloud node distributed in the user's family will be selected as the accounting node and constantly changed. At the same time, Xunlei united government actively cracked down on speculation, announced the firm no ICO, cracked down on third-party transactions, adopted the real name system, unlimited pre-sale activities and other means to resolutely curb the risk of speculation, so as to ensure the stability and sustainability of the player cloud and chain ecology
with the emergence of blockchain applications such as chaink, we can see that decentralized technology can make the instry no longer become so extreme, and all kinds of opportunities will burst out because of the introction of new mechanisms, which is of positive significance to the instry and the whole society
both sides mainly refer to the lender and the borrower, so they are called both sides
the borrower refers to the borrower, and the loan refers to the borrower
decentralized lending refers to matching the borrower and the lender through the past central lending agreement, and then transferring the assets and completing the lending immediately after the confirmation of mortgage and pledge
the decentralized lending protocol provides the platform with the technical basis of standardization and interoperability, and plays the role of security management in the lending process. Compared with the traditional lending model, the decentralized lending model has the following characteristics:
a. the combination of legal currency loan and digital asset loan (stable currency model can be regarded as the combination of legal currency and digital asset)
B. mortgage based on digital assets
C. realize real-time transaction settlement through automation, and rece the actual cost
D. replacing credit review with over mortgage mode also means that it can serve more people who can not use traditional services<
