Digital currency software construction

1. The proction of virtual currency needs a professional team, but if you make a direct currency, there is no wallet, there is no maintenance, and it's just a pure number, it's much simpler, the cost is very low, and a trading platform is thousands of yuan. However, there are serious loopholes in this platform and it is easy to be attacked
if you want to create a virtual currency like bitcoin, Ruitai coin and Qianjin card, you need to make some efforts. First of all, these coins need card method and a downloadable wallet. The application scenarios of this kind of currency have been determined. At the same time, you need to create a secure and reliable trading platform.

2. As for the business process and technology of digital asset trading system development, we thought for a long time that 80% of blockchain implementation needs business process changes, and 20% needs to find the technology behind it. In fact, a good project and a good market need the support of a strong technology research and development company. At the same time, you also need to have enough ambition to deal with the bottlenecks in the process of changing the business process. This month, the Hong Kong Securities Regulatory Commission (SFC) issued a new rule on digital assets, including the digital asset portfolio under the supervision of the SFC, and launched a "regulatory sandbox" plan for the digital asset exchange to study whether the digital asset trading platform can be regulated. The exchange development company believes that this news has a clear direction for those in the instry who need to manage digital assets and establish exchanges, and explore the sustainable development of digital assets and blockchain ecosystem. In the instry, doubts about digital assets and blockchain technology have been rising and falling, but the combination of blockchain and various applications has never stopped. Especially in Hong Kong, more market participants believe that this distributed network consensus mechanism is a disruptive technology. In view of the future development of exchanges, the key points of licensing adaptability are very beneficial to the global joint governance of the global market of digital assets. The entry of Wall Street tycoons such as the New York stock exchange means that the main force and "regular army" of professional level are running to enter the market to lay out digital assets, which indicates that bitcoin is more and more valued by professional financial investment institutions, and bitcoin will become more and more popular and be recognized and accepted by more people. The financial instry first embraces blockchain technology. This is mainly e to the high degree of centralization of traditional financial instry. There are a large number of centralized credit intermediaries and information intermediaries in the chain of traditional financial instry, which slow down the operation efficiency of the system and increase the cost of capital flow. Any "exchange" should be a big data company. In essence, it should be a data analysis company. It must know what time and space, what driving force, what transaction frequency, what expectation and what path users obtain information to decide the transaction
the foreign currency trading platform is built, and the blockchain digital currency exchange develops the following trading forms of blockchain exchange: 1. Price limiting transaction: price limiting buy / sell refers to that the user sets the price and quantity of a buy / sell currency, generates a commission order, and the system will automatically match the buy order and sell order in the market, Once the price set by the user is reached, the transaction will be executed automatically according to the priority of price and time. Yuanzhongrui exchange system development 2. Market price trading: market price buying refers to that the user only sets a total amount, generates the order, matches from the beginning of selling to the completion of the total amount. Selling at market price means that the user only 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. Currency transaction: currency transaction is mainly aimed at the transaction between virtual currency and virtual 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. 4. C2C transaction: both sides of the transaction release the transaction information of buying or selling coins 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. OTC OTC trading: it is a set of platform for offline purchase of digital currency 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
What are the characteristics of digital currency trading system 1) Digital currency trading system has rich functions, powerful and practical. The unique full interface functions of fast recharge, cash withdrawal, cash charging and cash withdrawal can provide customers with the most convenient means of fund transfer 2) Using the blockchain technology, and in-depth running safe and reliable price limit, market price, plan three transaction modes, a variety of free combination of transaction modes, fully covering the needs of users, using exclusive advanced algorithm to complete the transaction automatically 3) Digital currency trading system platform back office proprietary accounting mechanism to monitor the funds of all users, as well as multi-dimensional exclusive reports, to ensure that the funds are accurate. The so-called development of digital currency trading system can also be called a development project with blockchain technology as the core and other technologies as the auxiliary. You should also understand this sentence. In fact, blockchain technology is the most important technology in the development of trading system 4) Proprietary powerful log management to fully grasp the system state, to ensure the stability and security of the system 5) Digital currency trading system features user-defined settings, free and flexible system configuration and dynamic management of the foreground website, which brings great convenience to the use of the platform 6) Procts can use the existing virtual digital currency in the market, or can be customized according to their own needs, and then issue a variety of different algorithms of virtual digital currency, using the unique hot and cold wallet multiple encryption storage technology to ensure the security of virtual digital currency.

3. Compliance --- relevant qualification license plate
Technology Construction --- can be outsourced to the technical team
follow up maintenance --- publicity, market value management, etc.
if you are not clear, you are welcome to make friends

4. This is true, but it is small in scale in China. Just like ether and the Dao, it is very popular abroad, but it has no reputation at home. Explain the difference between China and foreign countries, just as bit will have the attributes of storage and investment later, similar to gold. Therefore, foreigners will hold it for a long time and invest stably. However, it is different in China. Everything can be speculated just like buildings and stock markets. And this currency seems to be relatively stable, and the platform has growth restrictions. It may be more like a platform, or similar to the bank's exchange currency and foreign transfer, but it is very convenient to exchange the core currency of their platform.

5. The point-to-point transaction mode of digital assets is a safe mode for people who want to develop exchanges. Peer-to-peer, indivial to indivial transactions, there is no illegal fund-raising, which avoids disrupting the market. Due to indivial to indivial transactions, many platforms like bitcoin want to transform!

6. Building a digital currency trading platform requires people's understanding, not everyone can create it. The most important thing of trading platform is security and user experience. These requirements for technology are very high, which is different from a simple display website
at present, the mainstream digital currencies are bitcoin, Ruitai, Laite, dogcoin, ethereum, etc.

7. Just find an outsourcing company. My friend's company does this

8. I haven't heard of it

9. The functions of these two interfaces are exactly the same, without any difference, except that their positions on the switch are different. Generally, the switch with 0 is built-in, and the switch with 1 is expanded, just like the stand-alone display and centralized display on the notebook. The centralized display is always at 0

Why develop digital currency? From the perspective of the central bank, there are six advantages:

first, to improve the convenience and transparency of economic transactions; second, to rece the high cost of the issuance and circulation of traditional paper money; third, to better support economic and social development; fourth, to help the comprehensive realization of Inclusive Finance; fifth, to rece money laundering, to promote the development of the economy and society Sixth, improve the central bank's control over money supply and circulation

steps of digital currency development:

the first step,

first, we need to download the source code of a blockchain system from git, such as choosing the backbone code of bitcoin to download the relevant source code

At the same time, prepare the corresponding compiling environment (c + + is recommended in Linux) and install the corresponding development environment and tools

the second step and

code all need to be compiled, so you need to prepare the compilation environment and tools, download the environment compilation tools, configure

system environment variables, QT environment and other files, and compile commands are described in detail in the files in ITC source code

however, the construction of the system and development environment, program compilation and other processes are cumbersome, so it is not recommended for ordinary users to make their own. For developers, it may take 2-3 days to install and configure for the first time

the third step,

take bitcoin development as an example, it is the development environment of Q. after downloading the source code and configuring the environment, open the source code of the bitcoin core in qtcreator, configure relevant files and compilers, and start to try to compile the client of the bitcoin core

Step 4,

transform into your own digital currency, open each source file, find the corresponding local adjustment parameters, such as adjusting

the number of coins in each block, the total output, the adjustment difficulty, and so on. Then the most critical point is to change the name to your own currency

name as you want, and don't forget to replace the related icons in the resource folder. If all goes well, after re compiling, your new coin will be invented successfully

for the development of this digital currency, the technology is relatively professional, so it is better to have a professional team to assist

framework for digital currency development:

1. Build Ethereum private chain test environment and public chain node environment configuration

2. Ethereum transaction and confirmation principle

3. Ethereum JSON RPC interface

4. Ethereum transfer and withdrawal principle

5. The server connects Ethereum public chain interface, and its own server stores business data, Public chain storage transaction anonymous data

6, private key security processing

the following is the development code example:

for example, the common digital currency wallets in the market are:

app class: kcash Imtokenweb: myethereumwallet Google browser plug-in: metamask

one of the most commonly used is imtoken

blockchain transaction technology concept:

let's take a look at how blockchain transaction is handled with bitcoin as an example. In order to send a certain amount of bitcoin to another wallet, you need the following information: the address to send the funds to your wallet, the amount of cryptocurrency you want to send

the ID of the recipient's wallet

each transaction is signed with a unique confidential private key. Once the payment is signed by the sender, it becomes publicly available. The transaction still needs to be confirmed so that the payee can get the money. In order to confirm the transaction, it is necessary to generate a new chain block

these blocks are generated by complex mathematical calculation to find the unique key. It takes 10 minutes to create a new block, and the person who finds the key gets a certain amount of coins as a reward. Once a new block of the chain is created, it is not possible to remove it from the database or change the information in some way. Therefore, blockchain transaction is final and irreversible

three core advantages of digital currency:

first, digital currency is a fair currency

digital currency has no specific issuing institution, is not issued by a country, only depends on a specific algorithm, which means that digital currency can not be manipulated by manipulating the number of issues, so digital currency is a free, non-state currency

we can see that there are many countries that directly recognize the virtual currency, so if there is a demand, it needs a trading platform

many investors who want to build a virtual currency trading platform now, why can't they go to these areas to build a trading platform? Building a virtual currency trading platform is a good business opportunity, isn't it

Second, the security factor of digital currency is higher.

although the emergence of paper money facilitates the transactions in our daily life, there are risks of being stolen and received. Although e-money can avoid these risks, there will be new problems such as theft and swiping

digital currency can avoid the above problems. And broadcast every transaction record on the network. Yes, all nodes save all the currency circulation information, so that any node can easily find the currency circulation before the transaction

Thirdly, the transaction of digital currency can realize anonymous transaction. Although you can query the flow information of each account according to the local complete transaction records

but we can't know who the owner of this account is, and no one has the ability to manipulate the digital currency on other people's accounts, which protects the privacy of users

if you also hold trading digital currency, foreign exchange gold, crude oil, contract Futures:
