Security of encrypted digital currency

1.

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

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 />

   

3. There are many advantages of encrypted digital currency. Here are two

1. Secure
transaction of cryptocurrency on the decentralized platform of blockchain, the E-wallet used by it is authorized to send and receive cryptocurrency by the cryptosystem using the unique public key and private key. And the account does not need to be identified by a third party, so outsiders can not know the identity of the trader
2. Tamper proof
after the transaction on the blockchain is confirmed, it is tamper proof, and this kind of data is traceable, so the illegal elements can't cheat by deleting or modifying the records
you can learn about cryptocurrency through some media platforms, so I won't go into details here.

4. 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.

5. 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.

6. The hottest time of encrypted digital has passed, and cryptocurrency was the hottest year in 2015. At that time, shortly after bitcoin entered China, people did not know much about cryptocurrency and worshipped it blindly. Now, people have graally become rational
since 2013, the popular digital currencies are bitcoin, Ethernet, lightcoin, DCT and so on.

7. Bitflyer, the largest bitcoin exchange in foreign countries, is headquartered in Tokyo.

With the advent of digital currency, the encryption algorithm of currency is becoming more and more important. What are the types of passwords

classical cipher types mainly include transposition cipher and rearrangement of alphabetic order messages. For example, "Hello world" becomes "ehlol owrdl"

Diffie Hellman and RSA algorithms have been widely used except for the first public example of high quality public key algorithms. Other asymmetric key algorithms include Cramer schup cryptosystem, ElGamal encryption and various elliptic curve techniques

some well-known cryptosystems include RSA encryption, Schnorr Signature, El Gamal encryption, PGP and so on. More complex password systems include e-cash system, signcryption system, etc. Now more cryptosystems include interactive proof systems, such as zero knowledge proof, which is used for secret sharing

for a long time, information collection and law enforcement agencies have been interested in cryptography. The importance of secret communication is self-evident. Because cryptography promotes privacy protection, it also attracts great interest of cryptography supporters. Therefore, there is a history of controversial legal issues around cryptography, especially since the emergence of cheap computers makes it possible to widely use high-quality cryptography

nowadays, cryptocurrency transactions are semi anonymous, which makes them very suitable for a series of illegal activities, such as money laundering and tax evasion. However, the proponents of cryptocurrency often attach great importance to the anonymity of digital currency and think that it can protect the privacy of users. Some cryptocurrencies are more private than others

Cryptocurrency is a new type of digital asset, which is based on the network distributed on a large number of computers. This decentralized structure enables them to exist outside the control of the government and central authorities. The term "cryptocurrency" also comes from the encryption technology used to protect the network

blockchain is an organization method to ensure the integrity of digital currency transaction data, and it is an important part of many cryptocurrencies. Many experts believe that blockchain and related technologies will subvert many instries, including finance and law. Cryptocurrencies have been criticized for many reasons, including their use for illegal activities, exchange rate fluctuations and the vulnerability of the infrastructure that underpins them. However, digital currency is also praised for its portability, divisibility, anti inflation and transparency
