How to issue currency in blockchain exchange system

1. Currency transaction
currency transaction is mainly aimed at the transaction between digital currency and digital currency, in which one currency is used as the pricing unit to purchase other currencies. The currency transaction rule is also to complete the matching transaction according to the price priority and time priority
C2C transaction
both sides of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the Seller shall make payment according to the reservation. When the transaction is completed offline, the platform, as an intermediary, charges a certain percentage of the handling fee from each successful transaction
OTC OTC trading
is a set of offline purchase digital currency platform independent of the exchange. Anyone can publish purchase / sale advertisements on the platform. The purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer.

2. Similar to the stock exchange, blockchain exchange is the website platform for digital currency trading. Xrv522 can develop blockchain exchanges. These trading platforms generally only provide functions such as recharge, transfer and cash withdrawal. In other words, they will only tell you the collection address of your wallet, while the key, keysore and mnemonic words of your wallet will not be provided. Identity authentication is completed through login user name, password, verification email, mobile phone and other ways
(1) introction to price limit trading mode:
price limit buying / selling refers to that the user sets the price and quantity of a buying / selling currency to generate an order. The system will automatically match the buying and selling orders in the market. Once the price set by the user is reached, the transaction will be automatically executed according to the price priority time priority
(2) introction to market price transaction mode:
market price purchase refers to that the user sets a total amount and generates a commission order, from the beginning of selling to the completion of the total amount transaction. Selling at market price means that the user sets the total number of currencies to be sold, generates a commission document, and matches it from the beginning of buying to the completion of the total number of currencies transaction
(3) introction to currency transaction mode:
currency transaction is mainly aimed at the transaction between virtual digital assets and virtual digital assets, in which one currency is used as the pricing unit to purchase other currencies, and the currency transaction rule is also to complete matching transaction according to price priority and time priority< (4) introction of C2C transaction mode:
both parties of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the seller complete the transaction offline according to the agreed payment method, and the platform, as an intermediary, charges a certain proportion of the handling fee from each successful transaction< (5) introction to OTC OTC trading mode:
it is a set of platform for offline purchase of digital currency independent of the exchange. Businesses can publish purchase / sale advertisements on the platform, and purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer, The technical construction problems of the exchange can be found on the Internet
(6) introction to trading mining mode:
the exchange platform returns a certain proportion of the commission income to the platform users, and the platform coin is returned. According to the principle of distribution proportion, the exchange platform takes a certain proportion as the mining reward. Mining refers to trading on the platform to graally unlock the platform coin until all the platform coins are fed back. This kind of play has a strong attraction to attract users< (7) introction to futures / contract trading mode:
futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price. The designated r period in which both parties have to trade in the future is called the settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter"< (8) introction to the trading mode of perpetual contract:
perpetual contract is a new and unique contract. The goal of the contract is to allow high leverage to the market conditions of the spot market. The contract will not be delivered and can follow the reference price index through various mechanisms. The contract evolved from the traditional futures contract, but the perpetual contract has more obvious advantages and greater risks than the traditional futures contract, supporting long short two-way trading, opening a 100 times leverage, permanent position, premium and so on.

3. We know that the state has always advocated "no money" blockchain. That is to say, don't use the chain&# 8204;&# 8204;&# 8204; Currency, support technology development, do not support issuing currency

of course, the coin here is what we often call token, which originally means token (temporary) in computer identity authentication. With the popularity of blockchain and digital currency, people have a variety of translations for token, including token, integral, certificate, logo, indicator, etc

the understanding of token in the market can be divided into two categories

in the first category, 99% of the people think token means token, because 99.9% of the projects do the same thing. Set up a foundation, build a website, write a white paper, and then go to ICO. Because most of the projects are still in the conceptual stage, token itself has no other meaning except trading, so people call it token, which performs the function of currency to some extent

in the second category, professionals and institutions are more willing to translate token into proof of equity, or token. For example, a person's identity certificate, academic certificate, equity, bonds, points, bills, etc., are authentic and tamperable because of the proof of rights and interests. Every proof of interest becomes more secure and reliable through the protection of cryptography

therefore, blockchain is not only a technology, but also a new mode of proction and organization, even a new thinking

so, the question now is, does the blockchain project have to issue currency

answer: you may not issue currency. Not all blockchain projects need to be issued with currency, and it is not necessarily blockchain projects that issue currency

for example, the alliance chain does not need to issue coins. For example, Tencent's q-coin, in principle, is also a kind of currency, but it is not a blockchain project

therefore, the two are not related, but if they are public chains, they need to issue coins. Why

let's take bitcoin as an example. Bitcoin system as a public chain must rely on the existence of bitcoin. Public chain obtains the stability and non tamperability of its system through the nodes distributed all over the world, and these properties are the basis for the existence of public chain

imagine that if the bitcoin system is unstable or can be easily tampered with, bitcoin will be worthless. These nodes are not set up by one or several companies, otherwise they are equivalent to private chain or alliance chain. These nodes must be built dynamically by many participants. And the existence of these nodes must need some kind of incentive, otherwise why do the builders of these nodes want to participate in your system. And this kind of incentive must be integrated with the blockchain system, and it must be money

then why is it currency, not legal currency, such as RMB, as an incentive

if RMB is used as incentive, because RMB should be stored in the RMB account, and the account itself is centralized, so it's easy to be controlled. Just think about why domestic bitcoin exchanges are so afraid of the central bank, and they are afraid of being weaned. In addition, RMB can't react with smart contracts within the blockchain

the electronic currency issued by the central bank can not be used as the original currency and incentive of a blockchain system. Why

if the central bank or a rich person wants to destroy a project, they just need to take out enough e-money to do enough nodes and attack 51%. Therefore, it is impossible to use the e-money issued by the central bank as the original currency and incentive blockchain system. However, blockchain projects with independent native currency and incentives have no such worries

If a person or organization wants to get enough nodes to carry out 51% attacks, it must first get more than 50% enough coins, and the amount of coins in the market is certain, so before it gets enough coins, the soaring price will make it hard for him to bear

therefore, a public chain project must have money. A public chain project without money is like a castrated person

in addition, only through the token and reasonable stimulation of output, can the proction relationship be changed and the value of blockchain be brought into play. Therefore, the project must have token, which can promote the development of the project faster. Token solves the problem of incentive and consensus, and incentive solves the problem of autonomy. The positive autonomous economic ecosystem and the underlying technology of blockchain are a perfect combination.

4. Stolen currency and being attacked should be a headache for the exchange and it is difficult to avoid. Large exchanges usually set up their own technical team to develop the transaction payment system. Small and medium-sized exchanges can dock with third-party technical service providers, so the cost of R & D and operation and maintenance is relatively low
the exchange I am familiar with uses the currency payment enterprise version, which is a digital asset security payment system. The general principle is to store the private key locally, bind the exchange's unique client with multiple encryptions, and the system itself does not save the private key, so as to prevent the possibility of digital currency theft from the source. It is also convenient to operate, with unified management of Multi Chain and multi currency and convenient reconciliation
hope to adopt.

5. In short, the current ICO is based on the currency issued by Ethereum, as long as a smart contract is established on it, and financing needs to publicize your contract address, so that others can automatically exchange your currency when they call eth. Finally, it is said that domestic ICO is prohibited

6. You can log in to the official websites of digital currency exchanges such as fire coin, coin security, biter, etc. Recently, the price fluctuation of bitcoin market is very small, basically in a horizontal state. Experts predict that bitcoin is bottoming out, so we might as well wait and see. If you learn to fry coins, acetoken, a quantitative robot, can learn about it.

7. I don't know much about this. If it's just the newly issued currency, I think it's quite unstable. I always feel that investing in Singapore dollar is a bit risky, so I don't know much about it. However, generally, there are multiple currencies on a platform. If it is good, it should also be on the platform, but it still depends on what platform you are looking at.

8. Aichichain wallet allows indivials or companies to issue their own digital assets. For each asset issued, a certain amount of TCC needs to be handed over to the system. All the paid TCCS will return to the public mine pool and be distributed to each node of the maintenance system through dpos.

9. Domestic virtual currencies are collectively known as "Shanzhai coins" in the instry. At present, few enterprises have the ability to develop Shanzhai coins. The role of blockchain in virtual currency is like a smart contract, which ensures the transaction security of virtual currency and solves the trust problem. Among the known enterprises, Yingtang Zhongchuang, which has strong application and development ability of blockchain, has developed many trading systems. Its development scheme for Shanzhai coin can be referred to.

10. Blockchain (English: blockchain) is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value of the previous block, which is connected to the current block from the original block to form a blockchain. Each block is guaranteed to be generated after the previous block in chronological order, and a distributed ledger Technology (DLT,
distributed
ledger
Technology) can also be understood. Its basic principle is to establish a public account book on the Internet, and the users in the P2P network will jointly keep accounts on the account book (the process of accounting is "mining"), and each miner will proce an account book. The problems of any miner in the blockchain network will not have any impact on the account book in the whole network, and no one can change or forge the account book.
