Digital currency without privacy

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

2. ​ In recent years, the speculation related to virtual currency (such as ICO, IFO, IEO, IMO and STO) has been in vogue. The price has gone up and down, and the risk has gathered rapidly. Relevant financing entities raise funds from investors or virtual currencies such as bitcoin and Ethereum through illegal sale and circulation of tokens. In essence, they are illegal public financing without approval. They are suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal crimes, which seriously disrupt the economic and financial order

on September 4, 2017, the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance", which cleaned up the ICO and virtual currency trading venues. The scale of domestic virtual currency transactions decreased significantly, effectively avoiding the impact of virtual currency prices on China's financial market.

3. There is no risk in the fixed investment of digital currency, which is relatively safe.

4. The anonymity of digital currency market is still there, which is also very popular. Although bitcoin has anonymity, its anonymity is not particularly good. Zcash is similar to bitcoin in many ways. First of all, it is also based on the distributed ledger (blockchain) for transactions. But there is one big difference between zcash and bitcoin: zcash is completely anonymous
according to the introction, zcash uses a technology called zero knowledge proof (known as "ZK snark") to verify the authenticity of the transaction. It uses a public blockchain to display the transaction, but it will hide the amount of the transaction. Viewing the owner of the key (i.e. the owner of the coin) allows others to view the information associated with the key
in short, this method of calculation allows users to prove that they have the currency they want without exposing information about where the currency came from or is going. It's like zero knowledge proof allows you to enter a password on a website and verify it by the website's server without actually transmitting the password
in contrast, although bitcoin and other digital currencies are famous for their concealment of transactions, in real life, they can often track transactions through the records of ordinary bitcoin blockchain, so that people can accurately know the sender and sending location of bitcoin. Nowadays, zcash has realized the transaction of original data in the form of encryption, rather than publishing the transaction data to the public like bitcoin. Snowden also said that the anonymous zcash project can solve the monitoring risk of bitcoin
therefore, zcash, an anonymous function that pursues the ultimate privacy protection, is first considered to have great value in the financial instry. Foreign media pointed out that the traditional financial instry has an extraordinary demand for information protection. Although many people think that the privacy requirements of bitcoin and other blockchain systems come from crypto anarchists and liberals, the fact is that the traditional financial instry is promoting the hiding of transaction information on the blockchain
however, the anonymity of digital currency is also a headache for the regulatory authorities, and it is very difficult to popularize it in the world. At most, it is only a niche proct. However, the platform developed by using blockchain technology has great potential. For example, the blockchain content publishing platform decent, Ethereum's intelligent contract and so on.

The central bank has recently been planning to launch & lt; Digital currency & quot; Now, some people think that since digital currency is going to be launched, does it mean that paper money will be replaced? In fact, paper money still has a place

01. The introction of digital currency conforms to the development trend of the times< p> in daily life, the use of cash is less and less , many of us now go out without cash, and there are more and more payment software. At the beginning, a treasure and a letter occupied half of the country, but now many people also start to use other payment software, and are no longer limited to these two kinds

when I used to go out, I used to go out with a certain treasure and a certain letter, but now I have a UnionPay. Every time I buy something, I can get a little discount. So, as long as conditions permit, I usually use UnionPay to pay. As an old saying goes, & lt; A little makes a lot;, Although each free amount is not much, but can not bear the large number of ah, in school, our school also has this payment software activities, a top ten, equivalent to white whoring a bowl of rice at noon, how good, so, UnionPay now in my heart also occupies a big position

summary:

it is impossible for digital currency to completely replace paper money, because many people still need paper money. I don't want my own capital flow to be clearly controlled by others in the future, and I need some private space

6. You can call 110 or go to the police station nearby
the police will protect your privacy
if you are cheated, you must call the police immediately. So you can recover your losses.

7. The answer is of course not. What the blockchain system needs to preserve is also targeted

8. At present, there are many problems in the application of digital currency, such as the confidentiality of transaction data, privacy and privilege mechanism, calculation and storage efficiency. Among them, operation security risk and privacy leakage risk are the basis of digital currency security. Therefore, it is necessary to study the construction of a new e-money security account model, the research on the key leakage tracking and revocation technology of distributed digital money account, and the research on the privacy and anonymity of e-money account, so as to establish a mechanism to ensure the security and privacy of digital money.
