Quantum digital currency

1. 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.

2. Cloud quantum coin is a compound interest disk, in fact, there is no value, it is just speculation. At the same time, compound offer is also known as the four typical Ponzi schemes. There is no relationship between quantum coin and quantum satellite. This trick is too bad
if you are interested in digital currency, it is suggested that you pay more attention to bitcoin, Leyte, decent, Ethereum and other mainstream digital currencies.

3. Buy a computer, quantum computing digital currency, in fact, you need to have a certain understanding before you decide

4. Most of the existing cryptocurrencies use elliptic curve cryptography, and elliptic curve cryptography may be cracked by quantum computer in 5-10 years. In order to resist quantum attack, Abe / ABI upgraded the existing encryption algorithm, and upgraded elliptic curve cryptography to lattice cryptography. Abe proposes lattice based linkable ring signature, and lattice based cryptography is one of the most effective methods against quantum computing attacks..

5.
investment in bitcoin is not so profitable now. All the financial procts I know belong to usury, and those with an annual rate of more than 24% are generally not protected by the state. As far as I know, the monthly profit of 30% are all pyramid schemes, such as BBT mint

of course, maybe you will refute me, because you do get the benefits, but if you don't get the benefits, will you invest more money, will you go to the top? This can go to the network about the Ponzi scheme.

6. Digital money qtum is a kind of quantum money.

7. Introction: quantum blockchain technology is a professional Internet technology service provider integrating computer software and hardware research and development, digital currency proction and asset management. Its main business is to mine the most core value digital currency in the world, especially bitcoin. It belongs to quantum blockchain Technology (Guangzhou) Co., Ltd
legal representative: Xu Rong
time of establishment: April 28, 2018
registered capital: RMB 10 million
enterprise type: limited liability company (invested or controlled by natural person)
address: 205, building 3, No. 6, Jiapin third Street, Shatou street, Panyu District, Guangzhou City

8. Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. 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)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin

based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior

6. Novacoin

another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities

the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward

7, infinitech

published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.

9. Domestic mainstream exchanges all support the purchase of RMB, but it's better to go to the larger exchange like okex, so as to have some protection. Secondly, it is suggested that before purchasing bitcoin, we should have a deep understanding of the market and some price fluctuations of bitcoin. Bitcoin has many problems in the market economy environment, which will affect the price of bitcoin. If you are satisfied with my answer, please accept it
