Digital currency in Sweden

1. 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.

2. The central bank's digital currency is the legal digital currency approved by the State Council. The central bank organizes market institutions to engage in the corresponding work of the central bank's digital currency research and development

2019 August 21st, the official account of WeChat central bank released two articles on digital currency.

3. There are more than a few kinds of real digital currencies in the world, but there are thousands of them, among which the well-known ones are bitcoin, Leyte coin, Ruitai coin, Qianjin card, doggy coin, Ruibo coin, dark coin, diandianbi, apple coin, Yuanbao coin, prime currency, bitstock, bityuan, etc.

4. Sweden does not issue digital currency
in Sweden, money is not issued by the government, but by private companies. At present, 80% of transactions in Sweden are made through electronic payment. Generally speaking, this means that the crime rate will be reced because the robbers have no way to get cash from someone or from the bus or even the bank
the cost of capital management is reced because there is no cash to transport and store
privacy is reced because e-payment companies are familiar with what their customers need
with the increasing dependence on technology, when the trading system is offline, people take other trading means
in the past few decades, the fraud rate in Sweden has continued to rise, which may provide a reason for adopting electronic payment measures
Digital cryptocurrency can bring many benefits to the electronic payment of private enterprises, such as increasing privacy and security. Compared with traditional electronic payment, digital currency is anonymous, but the ownership can be deciphered by a third party
here are several good methods: coinjoin can integrate multiple transactions; Coinswap can carry out very complex transactions, including two third-party transaction information, adding security protection on the blockchain. These methods can prevent privacy from being attacked. The whole system can be built on digital currency to improve its security
another advantage not mentioned above is that digital currency cannot be forged, which means there will be no counterfeit currency. However, there are risks in digital currency, such as the recent price fluctuations of Ruitai and Weimeng currencies.

5.

Sweden has been ahead of the world in the exploration of e-money. Although many countries are shouting slogans about digital currency, there is no movement in practical action. Sweden not only attaches importance to the research of digital cryptocurrency, but also makes practical action. In May of this year, Sweden already concted the pilot test of e-krona. Sweden is really interested in digital currency. It is also reasonable for Sweden, which is active in digital cryptocurrency, to become a cashless country ahead of China

because a slight error will affect the operation of the whole financial system, when you give up cash payment and completely rely on digital cryptocurrency, it means that there is no plan B when the system encounters a bug

8. Holding or managing securities

the most important point of bidding for a digital currency company and holding a license is to ensure the real operation of the company for a long time in the future. This is also the hope of the Swiss government that all digital currency business companies established in Switzerland will have a long-term and stable development. The real operation of the company includes an office building rented by an entity and stable employees

1

4

5. In addition to directors, 1-3 employees should be employed

6

7. The total processing time of Swiss digital currency is 7-10 months.

8. Countries are studying and analyzing the feasibility of digitizing their own currencies. Maybe Sweden will become the first country without cash flow< p> Sweden, the Nordic country, has always been regarded as a very conservative country. In fact, as early as many years ago, the proportion of people in their own countries using cash continued to decline. For example, if you buy a snack or a newspaper in a private store such as a buffet, the owner will directly display a card reader connected to his bank card, that is, the account of the bank card to which the money is remitted. In the absence of electronic payment terminals such as Alipay and WeChat, they use this way to avoid using cash. p>
