What is the full description of digital currency ADA

1.

digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)

digital currency has the main characteristics of network packets. 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 currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

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. SEC, the next generation of e-commerce blockchain protocol based on social trust, is the first blockchain system in the world to promote the socialization of e-commerce. In essence, SEC establishes the trust foundation of e-commerce indivials through distributed bookkeeping transaction relationship and trust endorsement, and takes it as the basis of consensus. SEC main chain can be used in commodity trading, second-hand commodity trading, virtual commodity trading, commodity equity, commodity crowdfunding and other fields. Under the strong wind of social e-commerce instry, SEC team will focus on the field of social e-commerce based on its own supply chain and user data
after the transfer of user terminals from PC to mobile phone, the e-commerce form has reached a new turning point, and is rapidly moving towards mobility, fragmentation and socialization. In three years, social e-commerce has occupied 14% of the market share of the whole e-commerce, with an annual growth rate of more than 100%. Once the share exceeds 20%, the replacement of traditional e-commerce will accelerate, just as traditional e-commerce will squeeze offline retail
based on WeChat's user volume and user time in China, the Chinese mainland market has been leading the global market in terms of innovation and market size. The main modes of social e-commerce include online Red e-commerce, content e-commerce and wechat circle of friends e-commerce. In essence, the three business models are based on personal brand and circle of acquaintances to establish trust relationship, and then attract users through content display
Social e-commerce has subverted the trust mechanism of traditional e-commerce in form, but there is no new trust solution mechanism to adapt to the P2P business model of social e-commerce, which restricts the growth of social e-commerce and model innovation in a higher dimension.

4.

Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. More generally speaking, digital currency is actually a commodity

just like gold, it took more than 200 years to be graally recognized by the world. In the early days, many people questioned gold's ability to store value. If we take digital currency as a substitute, people's questioning attitude towards gold in the past is equivalent to many people's attitude towards digital currency now

extended data

digital currency is a balance between financial security and innovation ability. Financial instry should have clear access threshold. Digital currency involves finance, so it must have clear access threshold. The enterprise qualification of blockchain and digital currency needs to be reviewed and an access system set. One of the core of supervision is that blockchain enterprises must have qualified technical personnel

for example, enterprises of different levels in the construction instry need different levels and numbers of registered structural engineers to ensure the safety of buildings and bridges, which can also be used for reference in the supervision of digital currency. In addition, investors need to refer to the requirements of the "measures for the appropriateness of securities and futures investors" issued by the CSRC, and only those who meet certain conditions can participate in the investment

5.

Digital cryptocurrency is a kind of currency that is not issued by legal tender institutions and controlled by the central bank. It is based on the open source code of a group of equations calculated by computers all over the world, and is generated by a large number of calculation processing of computer graphics card and CPU. It uses the design of cryptography to ensure the security of all aspects of currency circulation

6. First of all, what ADA does is the concept of smart contract. I think you should be familiar with smart contract, but for some new people, I still want to explain. The so-called smart contract is to write a contract that the computer can understand through the programming language, because there is no need for a third party, and the executor of the contract is a selfless computer, so it solves the problem of trust between people. For details, please refer to GitHub smart contract
Ethereum is a blockchain smart contract. Now Ethereum ranks 2-3 in the market value ranking, with a market value of 25% of bitcoin. However, Ethereum also has some problems, such as slow trading, high fuel costs and the mining mechanism that has been criticized repeatedly. Familiar? All of bitcoin's problems are with Ethereum. Some time ago, the Ethereum cloud cat game developed on Ethereum went online in the first week, directly blocking Ethereum's trading network. I tried to pay a high gas fee of nearly 100 yuan, but I still couldn't transfer it successfully. This can't help but lower my expectation of Ethereum. Ethereum is a great idea of V God, but after all, it is a pioneer, and there is a long way to go from perfection.

7. Miner is composed of high-end graphics card, a miner to use a lot of high-end graphics card composition. There are a lot of loaders, so the price of graphics card will rise naturally. It's all taken to the loader.
