Introduction to sea digital currency

1. Block eye analysis: digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions). In short, it is the electronization of RMB, which is equivalent to paper currency, but more flexible than paper currency. It can track the flow of your money and pay without the Internet
digital currency has the main characteristics of network packet. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital money, the direct benefit of digital money to the central bank is not only saving the cost of paper money issuance, circulation and settlement, but also enhancing the central bank's ability to control funds.

2. Here's a brief introction to several mainstream digital currencies to give you a rough idea. After that, I will talk about the specific currency from time to time

bitcoin is the originator of digital currency and the most valuable virtual currency. Because blackmail virus only takes bitcoin, it has entered the public view. The soaring price of bitcoin in 2017 has attracted a large number of investors to enter the digital money market. Because the number is small, it is only 21 million, which has a strong deflationary attribute
of course, I am extremely optimistic about the future of bitcoin. Of course, many people are not optimistic about digital currency. Here, it is most pertinent to quote Krugman's view:
"at least for now, buying bitcoin is still a good investment. But that doesn't mean the experiment was successful. The original intention of establishing a monetary system is not to make those who hold money rich, but to make transactions convenient and benefit the whole economy. And none of these bitcoins came to us. "
reborn currency
a protocol currency issued by reborn, which is the base currency of reborn network. It can circulate in the whole reborn network, with a total amount of 100 billion, and graally decreases with the increase of transactions. Reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system, Ripple labs (formerly known as opencoin) is the operating company of ripple coin
unlike bitcoin, reborn is a kind of transaction protocol, which is called smart contract in technical terms. It supports people to pay in any currency, and does not need a central data exchange center, so the transaction confirmation time of ripple is only 35 seconds, while that of bitcoin is 10-40 minutes

Ethereum
Ethereum is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer
there is a key difference between the blockchain technologies used by Ethereum and bitcoin. Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
unlike bitcoin, the value of Ethereum depends on whether the applications on the platform of Ethereum are prosperous or not, just like the price of oil will rise with more machines using oil

bitcoin cash
bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block
strictly speaking, however, there are different opinions on whether this is a new branch of bitcoin or another kind of "counterfeit currency". But now the offer of bitcoin cash is nearly 20000 yuan, so it's not too much to use it as a kind of "Shanzhai coin" to divide bitcoin traffic

IDA coin, ADA in English, is a proct of Cardano project. The total amount of Aida is 4.5 billion yuan, and 3 billion yuan will participate in the subscription. Among them, 2.5 billion ADA will be used for platform subscription, 500 million for the financial support of the development company's operating company, and 1.5 billion ADA coins will continue to be issued in the form of block awards
Cardano is a project started in 2015 to change the way cryptocurrency is designed and developed. This project is aimed at technical reformers, technical improvements to bitcoin and existing platforms. If bitcoin, Ethereum and other projects have many other shortcomings, Cardano can solve them<

lightcoin
a currency based on bitcoin protocol, but it does not require very high computing power, and it can also be mined by ordinary computer. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
for a long time, there has been a voice that "lightcoin will replace bitcoin", which is impossible. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin<

stellar currency
stellar currency, a digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and legal tender. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
star is a diversified team. The board members include Keith rabois, former COO of square, Patrick collison, CEO of stripe, Jackson Palmer, co-founder of dogcoin, and naval Ravikant, co-founder of angellist, who will be the consultant of the project< New economy movement, or NEM, was founded on January 19, 2014. The founder is a mysterious person in bitcointalk.org forum called utopianfuture. The original intention of utopian future was to build a second-generation digital currency NXT. He then realized that NXT's distribution model was unreasonable, so he devoted himself to NEM with egalitarian distribution
as a kind of cryptocurrency, new coin does not need much computing resources to maintain the operation of nodes. The proof of importance (POI) engine of NEM reces the threshold of computing resources to participate in non-traditional blockchain<

dascoin
formerly known as black coin, is a kind of counterfeit currency of bitcoin, which focuses on anonymous function. There are many innovations, such as master node network, fast payment, mixed currency anonymous technology, proposals can vote, and developers have fixed budget support. The core consists of a unique incentive P2P network. Miners are rewarded for maintaining blockchain security; The main node holders are rewarded for verifying transactions, storing data and providing a variety of services
the feature of anonymity meets the needs of some investors for absolute privacy. Although bitcoin is also widely used in money laundering and other illegal transactions e to its anonymity, it is only "pseudo anonymity", and the transaction of bitcoin can still be traced back to the traders themselves.

3. Digital currency platform development needs professionals to be responsible for, but now digital currency technology has matured, the difficulty of development has become very simple, has become a standardized technology. Today's digital currency technology is not the highlight, but the application scenario of this kind of digital currency
the birth and popularity of bitcoin all over the world depends on the concept, which is in the foreword of the times. However, bitcoin has been preconceived and cannot be replaced by other digital currencies. Although some counterfeit currencies were popular for a while later, they slowly went down in the end, only bitcoin strengthened. Puyin is another shortcut, as a standard system of digital currency appears, behind the endorsement of related tea assets, its value is recognized by the society.

4. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digital currency (digiccy)
digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by central banks or authorities, nor linked to legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded electronically

5. First of all, if we want to develop digital currency, we must have a comprehensive understanding. Since the governor of the central bank proposed the concept of digital currency, many small partners are eager to try, looking for digital currency development tutorials everywhere on the Internet, hoping to keep up with the pace of the times. This is a good thing. However, we need to know clearly what the purpose of developing digital currency is. If it's out of interest, OK, you can study the online course yourself until you can develop digital currency yourself. But if it's for long-term development, it can't be so sloppy. We must clearly know what matters needing attention in the development of digital currency, including the way to solve the problems encountered in the development is the most effective

secondly, we should be careful in the development process. Digital currency development course can only give us a general guidance, and the specific operation should be carried out by special personnel. Compiling mining tools is to understand the use of norms, and then operate. Now if the ready-made code on the general network does not support our algorithm, we have to re-examine the code, and then try again and again. If there is a problem in any step, all previous achievements may be wasted, so caution is the key

finally, in fact, the advantages of specially assigned R & D outweigh the disadvantages. Because the digital currency development course is not so easy to master. Even if it is a simple algorithm modification, the general experts need to spend more than a month! If we really want to develop digital currency for long-term development, we suggest that you find professional institutions. Although it costs a little money, it saves time and avoids loopholes. Only in this way can we safely develop digital currency!

6. We should focus on three aspects: popularity, innovation, operation mode and team

popularity: there is no doubt that bitcoin and lightcoin have the highest popularity in the cryptocurrency circle. Even though they have many shortcomings, they still have the largest number of players and the highest amount of money. They have large plates and are not easy to be controlled by the makers. Of course, the relevant infrastructure is relatively perfect

Innovation: dog coin is popular because it caters to the western small reward culture. The reason why Fuyuan coin can become the leader of the new generation of cryptocurrency is that it mainly focuses on the currency business circle, which is an applied cryptocurrency

operation mode: for example, the operation mode of Vicat coin has been exposed as pyramid selling. Although Yuanbao coin has been criticized before, the operation team will not give up, and Yuanbao coin is still the leader of domestic currency.

7. Pishon is OK, volume and price fly together, get the biggest bonus in the coin circle, the platform is formal, many people know it

8. Careful investment, if you are in some stock exchange group to see other people's earnings, you must pay attention, it is likely to be a fraud. Generally, there are two forms of digital currency scams. One is air currency, which is issued first. As you say, just like new shares, how rare and how many relationships do you need to buy, how many times do you need to buy it, and how many times do you need to buy it, and so on. Some people will print screenshots. These are all analog forms. Moreover, there is a lock up period for buying, so the basic money can't be put forward. There is also a form of trading with leverage, which is the same as futures. You can make a lot of money, or you can burst your position in an instant, making you lose all your money. If you don't invest more than one million assets, don't dream of making a fortune, or you won't even know what's going on.
