How to access digital currency
in the mixed market, how to practice a pair of eyes to identify the authenticity, this paper provides several perspectives for your reference
First, technical basis. The value of bitcoin does not lie in its price, but in its technical basis - blockchain, also known as distributed ledger technology. It is an Internet database technology, characterized by decentralization, openness and transparency, so that everyone can participate in database records. This paper is not a popular science article, and does not do too much entanglement on the technical explanation. But you need to understand the basic characteristics of blockchain. The first is decentralized and intermediary trust. There is no backstage, no manipulation, and no need for a third party. The second feature is its stability, reliability, persistence and security. Because it is a distributed network architecture, no central node can be attacked, so it has stronger stability, reliability and persistence in the overall technical layout. At the same time, the consensus mechanism does not need the entry of a third party, but through a technology, a previously scheled technology to achieve the completion of the whole transaction. The third is the openness, transparency and non tamperability of the transaction. So when we look at digital currency, we must look at its technical basis. Only when the technical basis is in line with the actual digital currency can it have investment value Second, trading platform. Investment in digital currency is inseparable from the trading platform, so it is very important to choose a reliable trading platform. A good trading platform should have the following characteristics. First, it is fair and impartial. All traders are treated equally without any discrimination, regardless of the size of the transaction volume or the geographical location. In particular, as an exchange, it can not issue money. How can it be fair and just to be a referee and an athlete? Second, freedom of advance and retreat, without artificial barriers and obstacles. Free registration, free use (not transaction costs). There are no restrictions on the freedom of deposit and withdrawal. Your own money is up to you. What needs to be pointed out here is that today's exchanges are all unregulated. They are also in a period of barbaric growth. Like digital currency, there will surely be outstanding people who will become the benchmark after the waves, and there will also be runners who will leave behind a lot of chicken feathers Third, monetary characteristics. It refers to the characteristics of a digital currency. A look at scarcity, that is, its circulation. Bitcoin is 21 million. There are many behind it. There are tens of billions and hundreds of billions of bitcoin. If the amount of bitcoin is too large, it is difficult to pry. Second, the theme is the entry point and application basis of a digital currency, from which we can see the social responsibility and existence of the digital currency. Nowadays, there are various themes, such as tips, watching Japanese AV, keeping virtual pets, naming planets, symbiotic economy, and so on. Different people have different opinions, but human society still has common basic values. As an investment, we should firmly grasp this point Team background. The spirit of enterprise is the embodiment of human spirit. What a liar opens can only be a liar company. Therefore, in the face of a digital currency, it is also important to understand the background of its creative team members. What is the common goal of the team? What are the common interests? Which stage of development is currently in? This seems to be a bit difficult, but because we have the Internet, we can still do it, just don't believe what he saiddigital currency investment, in the final analysis, is a technological activity, the key lies in learning and communication. Finally, the value of bitcoin lies in that it has led an era and successfully carried out a popular science ecation for the people on earth. In the future, the dominant digital currency will be the kind of digital currency that covers the world and is endorsed by the common value (such as gold), at least at a certain stage
the Internet will not die out, and digital currency will eventually move towards standardization and orthodoxy. As an investor, are you ready
warm tips: the above explanations are for reference only, without any suggestions. There are risks in entering the market, so investment should be cautious. Before making any investment, you should make sure that you fully understand the nature of the investment and the risks involved in the proct. After a detailed understanding and careful evaluation of the proct, you can judge whether to participate in the transaction

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 toolsthe 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 recordsbut 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
