The digital currency of the central bank is DCEP

the name of the digital currency developed by the central bank is DCEP (digital currency electronic payment). DC is digital currency. EP is electronic payment. Payment transmits digital things through a certain way, not paper currency. Therefore, electronic payment itself has the attribute of digital currency

The characteristics of digital currency are: low transaction cost; Fast trading speed; Highly anonymous

Application of digital currency

I. fast, economic and safe payment and settlement

cross border payment helps RMB internationalization. In 2015, the settlement volume of cross-border payment involving current account is about 8 trillion yuan. To accelerate the internationalization of RMB, cross-border payment and settlement procts and solutions with low cost, high efficiency and low risk are needed

At present, there are still a lot of repetitive human work in the bank's electronic loan process and processing process, and as the basic support of loan issuance, many of the collateral has the situation of false pricing or multiple or even no collateral. We can consider using digital currency to price and track bank collateral:

3. Bill finance and supply chain finance

in recent years, various bill market businesses based on commercial bills have grown rapidly, and bill financing procts have become a hot area of Internet financing. However, about 70% of the current bill businesses in China are still paper transactions, Supply chain finance is also highly dependent on labor costs

2. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Fire coin network, okcoin and coin security network are the three major bitcoin trading platforms in China. Due to the high risk of bitcoin trading, it is recommended to choose carefully for users with immature investment experience

There are four different definitions of EOS, specifically as follows:

1, EOS: electronic and electrical

electrical over stress (EOS) is a common cause of damage to components, which is manifested by overpressure or over-current to proce a lot of heat, so that the internal temperature of components is too high to damage components (commonly known as burn out), It is a common way to damage electronic devices caused by pulse in electrical system

Embedded operating system (EOS) refers to the operating system used for embedded system. Embedded operating system is a kind of widely used system software, which usually includes hardware related underlying driver software, system kernel, device driver interface, communication protocol, graphical interface, standardized browser and so on

embedded operating system is responsible for the allocation of all software and hardware resources, task scheling, control and coordination of concurrent activities. It must reflect the characteristics of the system in which it is located and be able to achieve the functions required by the system by loading and unloading some moles

(3) EOS: Ethernet based on SDH

POS (packet over SDH) and EOS are two different ways to implement IP services in SDH network. POS technology appeared earlier, EOS appeared later, and some technical evolution has been made

The main difference between

and POS is that the Ethernet frame is encapsulated first, then mapped to the VC (virtual container) of SDH / SONET, and then the information is processed according to the cross mapping system of SDH

4, EOS: blockchain

EOS can be understood as enterprise operation system, which is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture, which aims to extend the performance of distributed applications. Note that it is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

extended materials:

the characteristics of block chain (EOS)

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of block chain, it supports multiple applications to run at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers. When you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value

4. Q: What is blockchain technology? A: Blockchain technology can be understood as a public accounting mechanism. It is a technical solution rather than a specific proct. The basic idea is to establish a set of public account books on the Internet, in which all users in the network keep accounts and check accounts together, so as to ensure the authenticity and non tamperability of information. The reason why it is called "blockchain" is that the structure of blockchain storage data is composed of a chain of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time, and the chain continues to grow over time. Q: What is the relationship between blockchain and bitcoin? A: Bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin. Q: What are the technical features of blockchain? A: Based on open source software and peer-to-peer network, blockchain can bring more advantages than traditional network in currency related fields such as transaction payment. These advantages include: decentralization, no need to trust the system, disintermediation, tamper proof, encryption security. Q: How does blockchain technology improve the authenticity and non tamperability of data? A: The newly added data blocks are linearly added to the end of the original block in chronological order, which constitutes the blockchain. In this process, the data is distributed in each computer. This decentralized storage method improves the authenticity and non tamperability of the data. When a transaction occurs, users all over the world can act as regulators. If we do not recognize the legitimacy of the transaction, the transaction cannot be concluded, and the data on the blockchain is maintained by us collectively. Q: Is there any potential defect in such a brain burning "blockchain"? A: Blockchain also has some defects to be solved, such as security risks, work efficiency and resource consumption. Since the supervision of blockchain depends on all nodes in the network, theoretically speaking, if you master more than 50% of the computing power of the whole network, you will be able to successfully tamper with and forge blockchain data. Secondly, e to the distributed storage, each node in the blockchain needs to keep a database, and any transaction in the network needs to be authenticated and recorded by other nodes, so the efficiency of the system is low. Finally, because the operation of the blockchain relies on the computing power contributed by the network nodes, these computing power do not proce actual social value, so it is generally considered that these computing power resources are "wasted". Application of blockchain in various fields when blockchain technology is published, many people think it is possible to realize DAC. DAC (full name) can be translated into distributed autonomous system, which refers to an organization system that runs autonomously without intervention and management through a series of open and fair rules. DAC has many forms. It may be a digital currency, a system or an entity, or even a driverless car. This kind of organization system can provide valuable services for customers in the form of currency transfer (such as bitcoin), asset transaction, domain name service, or any other business model. Therefore, through the idea of information sharing, blockchain technology is likely to bring profound changes in cost rection and security improvement to various instries. Application scenarios that existing blockchain technology can achieve: proof of existence can be used to confirm rights in the field of Internet finance, that is, blockchain can really realize "proving your mother is your mother". The smart contract guarantees the validity of the contract, such as the generation required by the electronic signature law; Reliability of methods for storing or transmitting data messages; The reliability of the method of maintaining content integrity; The reliability of the method used to identify the sender. The blockchain of the Internet of things can solve the problem of the coding standard interaction interface of the Internet of things. When an e-signature is signed by identity verification, the signature data is only under the exclusive control of the signer. Any changes to the e-signature after signing can be found, and any changes to the content and form of the data message after signing can also be found. The market forecasting community, August, is an example. Anyone can access and use August anywhere in the world, which may bring unprecedented liquidity and trading volume to the market. Asset trading NASDAQ OMX Group Inc is testing blockchain technology, which NASDAQ believes has the opportunity to transform traditional financial trading methods into bitcoin like ones. The bitcoin mode of e-commerce can be applied directly. Is it possible for e-commerce to become a "harmonious" market without supervision? Social news magmavc has invested $400000 in getgems (formerly known as gems), a start-up project for decentralized social communications applications. File storage directly impacts and even subverts the traditional cloud computing architecture. Chain, a data API blockchain API service provider, has received a $9.5 million investment led by Khosla ventures. Wall Street's financial companies are investing in blockchain and seizing the beach. Visa, NASDAQ and Citigroup also invested in chain, an old Jinshan blockchain start-up, with a financing amount of US $30 million. In the financial field, what can blockchain do? Specifically, in the financial field, in addition to providing a trading platform for bitcoin, Jiuding investment believes that blockchain technology can also greatly improve various asset trading systems other than the existing digital currency. For example, it plays an important role in the post transaction market proceres such as the liquidation and settlement of financial derivatives, foreign exchange, private equity, energy credit linked investment procts and other assets. In terms of speed, the time required for settlement audit in the U.S. securities market is 2 to 3 days. The application of blockchain technology is expected to rece the settlement audit time from hour level to minute level or even second level, thus recing the settlement risk by 99%, and recing the capital cost and system risk. In the blockchain, transaction confirmation and settlement are carried out at the same time. After the node transaction is confirmed by the system, it is automatically written into the distributed ledger, and the corresponding distributed ledgers of all other nodes are updated at the same time. The automatic operation mechanism can greatly shorten the settlement cycle. In terms of expenses, under the current settlement mechanism, in order to achieve a shorter settlement cycle, it is necessary to increase the settlement cost and initial investment expenses significantly. The emergence of blockchain technology makes it possible to rece the settlement cycle more efficiently and quickly, and rece the transaction intermediate proceres, so as to save a lot of money, which is the market space of the related blockchain instry. In terms of security, the integration of blockchain technology into smart contract technology can process complex derivatives transactions programmatically, making clearing more standardized and automated. The time linear stacking feature of the block itself can help the regulators identify and discover illegal operations. At the same time, the smart contract can change the compliance inspection into automation and minimize the possibility of violation from the beginning of liquidation. The 24-hour uninterrupted operation of blockchain technology can also make the data exchange processing of Pan state exchange more stable and reliable. In addition to securities transaction settlement, blockchain can also be used to register and issue digital asset ownership. Blockchain technology can greatly enhance program automation, while smart contract can write many complex derivatives trading terms into the registration and issuance program supported by blockchain technology. When a transaction occurs, blockchain network can quickly and correctly execute. In November 2015, LINQ, a new blockchain technology project cooperated by Nasdaq and chain, has completed the first private equity transaction using the blockchain based issuance and trading platform. The application prospect of blockchain in the field of accounting has also attracted the attention of a large number of people in the instry. Accounting, auditing and compilation cost a lot for global enterprises and the four accounting firms. Automatic accounting based on blockchain technology can greatly rece the relevant costs. The company does not need to recruit special auditors to audit the account book, and all transactions can be stored in the internal blockchain. Due to the irreversibility and time stamp function of the blockchain, the external auditors and regulators of the four major accounting firms can monitor the company's account books in real time by tracking these blockchains. At the same time, the institutions can greatly rece the dependence on the auditors to audit financial transactions and make the audit business more efficient. With the increasing maturity and application expansion of blockchain technology, blockchain start-ups in developed countries have sprung up. At present, the world's leading blockchain companies generally focus on transaction, payment, clearing, Internet of things and other pain point businesses. Some companies have achieved a certain scale, and have developed a relatively clear business model. At the same time, many companies have extended their business in the blockchain instrial chain, covering payment, transaction, risk control, etc., making full use of the multi-point coordination effect. At present, Jiuding investment is also focusing on the projects and applications of various blockchain technologies.

5. 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!

6. Dodo coin is a decentralized trading platform, which uses the active market maker (PMM) algorithm based on Ethereum and coin safety intelligent chain (BSC) and has a capital efficient liquidity pool, which can support a single token provision, rece permanent losses and minimize traders' sliding point. The platform also provides smarttrade, a decentralized liquidity aggregation service that routes and compares various liquidity sources to quote the best price between any two tokens
in addition, Dodo removes barriers to the creation of liquidity pools for new asset issuance, such as asset ratios, liquidity depth, handling rates, and other parameters that can be customized and configured in real time. Dodo has also launched crowdpooling, an unlicensed equal opportunity liquidity proct, as well as customizable technology solutions for market makers in the professional chain

dodo token is a kind of governance token, which can also provide transaction fee discount and crowdfunding / Ido allocation on the platform to holders. The Dodo token can be mortgaged to mint vdodo, which is a non transferable token and can be used as proof of membership in the Dodo loyalty program. Compared with other AMM platforms, the permanent loss on dodo is reced. On dodo, there is no AMM specific permanent loss e to asset reallocation. Limited partners do need to be wary of market / inventory risks associated with market making<

1. The meaning is different: D is the differential symbol, DX is the differential of X, this concept is not the same, we should pay attention to distinguish when applying

Different objects: D / DX is the differential of a function to x, dy / DX is the differential of function y to X

Different understanding: DX can be understood as the differential of variable x; Since x is usually regarded as an independent variable, it can also be understood as the differential of the independent variable x (that is, the differential of the X axis). Dy / DX represents the derivative of the function y with respect to x with respect to the independent variable x

< H2 > extended data:

D / DX: meaningless, which can be understood as the derivative of a function to the variable x (also known as differential quotient), followed by differential function. For example: (D / DX) (x ^ 2) represents the derivative of function x ^ 2 to variable x

dy / DX: denotes the derivative of the function y of X to the independent variable x, which can also be expressed as y & # 39; without any confusion
