Does digital currency need quantum encryption

1. It's not illegal to issue digital currency in China. It doesn't need the next three years. Now people have already issued digital currency. For example, Ruitai, bitcoin, Yuanbao and sandcoin are all digital currencies issued by domestic companies. But if not

2.

Differences:

non encrypted currency (enterprise currency):

1, personal behavior

2, company's own currency

3, unable to decentralize

4, unable to trade on international trading platform

5, unlimited issuance

6, no mine website, no original code

7, controllable price, mostly one-way relationship (dining ticket of an enterprise, Qmoney and so on)

open source digital cryptocurrency:

1. Decentralization -- not regulated by indivials, companies and national banks

2. Limited issue

3. Free trade on international trading platform

4. Original code

5. Not taxed, not frozen, uncontrollable price

cryptocurrency advantages:

1. Compared with paper money, Save the cost of printing, data audit, anti-counterfeiting, escort circulation, safe keeping and so on

2. It is impossible to control the number of issues without issuing institutions

3. Borderless. If you use cryptocurrency transaction, directly enter the account address, click the mouse, wait for the network to confirm the transaction, a lot of money will pass

4. Using cryptocurrency in any store can save the cost of tax and capital supervision

5. It is not controlled by the central bank and the quantity is limited, so it can completely resist the pressure of inflation. Let the wealth of the common people keep its value and increase its value The cryptocurrency other than bitcoin is also known as counterfeit currency and competitive currency (English: altcoin). Part of it is a virtual currency similar to bitcoin, which is based on the ideas, principles and source code of bitcoin. At present, more than 800 cryptocurrencies are in circulation

because bitcoin itself does not have an authoritative issuing institution and state power to maintain its authority and uniqueness, bitcoin and its imitators can only get along equally. It is not absolutely exclusive

3. One of the key technologies of digital currency is elliptic curve encryption, which is the core technology of digital signature of cryptocurrency. It can ensure the ownership, non plication and transaction integrity of cryptocurrency. But with the advent of quantum computers, it will no longer be secure. The quantum attack of quantum computer can solve the underlying mathematical problems, and the digital signature based on elliptic curve encryption can be forged. This is fatal for cryptocurrency, because the records of distributed ledger can not be tampered with and reversed. If elliptic curve encryption can be broken, then the security foundation of cryptocurrency will no longer exist.

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

1. definition of digital currency:

   digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy< br />

   

6. Cryptocurrency is legal in China. Encrypted digital currency is a part of digital assets, and QQ, game accounts, game equipment are protected by law in China
encrypted digital currency generally refers to bitcoin, Ethereum, lightcoin, DCT and other open source currencies.

7. Different people have different opinions on this issue! A lot of people and the media questioned it. But there are still a lot of people playing. The yield of this kind of currency may be relatively high, but it is unreliable. It is suggested to invest in digital currencies such as bitcoin, Ruitai coin and Qianjin card.

8. Network gold is called network gold integral, or EGD for short. It can also be called global general business integral. EGD is a virtual currency born with the Internet. It can act as the characteristic of currency. The virtual currency that can land and connect with entities is virtual currency. EGD will soon be split to buy by gram. The company will issue international visa cards to every enthusiast who purchases and holds online gold. They can swipe cards to withdraw cash internationally. The Prime Minister of Thailand, the Prime Minister of Russia and Mr. Li Ka Shing have all purchased the collection, and Cheung Kong instry, which is 100% controlled by Li Ka Shing, has designed a dedicated consumption POS machine for EGD, which can be used to swipe savings card, credit card and EGD. This year, it will be fully launched. At present, the dedicated single ATM is placed in Shanghai and Chongqing. Princeton University of the United States has signed a training program with Peking University and Nanjing University. Upon completion, it will issue a digital asset certificate recognized by the American market!
