1. digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form. Digital currency is a kind of venture capital. Some people can make profits in this market, while others can make losses in this market. To make money, digital currency can be invested by mining and trading on the platform. Digital currency has price fluctuation and is investable in theory

2. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis
above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

3. No, only at the beginning of the issue when the price is lower, you can buy as an investment, after appreciation is good, devaluation, their own bad luck.
4. The Internet of things is a general term for an instry, such as the automobile and rice instry.
if someone says that this is the original stock currency to send points and personal information, it can be basically confirmed that it is MLM

5. We should focus on three aspects: popularity, innovation, operation mode and team
popularity: there is no doubt that bitcoin and lightcoin have the highest popularity in the cryptocurrency circle. Even though they have many shortcomings, they still have the largest number of players and the highest amount of money. They have large plates and are not easy to be controlled by the makers. Of course, the relevant infrastructure is relatively perfect
Innovation: dog coin is popular because it caters to the western small reward culture. The reason why Fuyuan coin can become the leader of the new generation of cryptocurrency is that it mainly focuses on the currency business circle, which is an applied cryptocurrency
operation mode: for example, the operation mode of Vicat coin has been exposed as pyramid selling. Although Yuanbao coin has been criticized before, the operation team will not give up, and Yuanbao coin is still the leader of domestic currency.

6. The issue of bitcoin is determined by the block height, that is, the distance from the No. 0 block of Genesis. Now when the number is reached, the total amount of bitcoin should be limited. After this village, there will be no store. If the miners dig a block but don't receive the reward of the block, the bitcoin will be destroyed forever
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block

7. On April 14, a screenshot of the digital currency DCEP personal wallet app spread wildly on the Internet. According to the news, the central bank's digital currency DCEP has been tested in some banks, which means that the central bank's digital currency is about to come out. So how can the central bank buy it after issuing legal digital currency
it is understood that the research and development of legal digital currency in China started in 2014. In order to promote the research and development of digital currency, the central bank has also set up a digital currency Research Institute. The project of the central bank's digital currency is called DCEP, which is also called digital currency and electronic payment tools. In recent years, the research and development of digital currency has accelerated in China. At present, in addition to the internal test concted in Agricultural Bank of China, DCEP has also been concted in several other major commercial banks
Mu Changchun, director of the digital currency Research Institute of the central bank, said that the functional attributes of the digital currency launched by the central bank and paper money are identical, except that the digital currency is a kind of legal tender in digital form
many friends who have invested in bitcoin and other digital currencies want to know how the central bank purchases digital currency after they hear that the central bank is going to issue digital currency, but I'm afraid they will be disappointed. The digital currency issued by the central bank is legal tender, which is equivalent to a substitute for paper currency. Compared with paper currency, digital currency is just a change of trading medium, The functions and properties of the two are the same. Just imagine, who would use a 100 yuan note to buy a 100 yuan digital currency
specifically, the legal digital currency issued by the central bank does not pay interest and can be used in small and high-frequency business scenarios. Because the central bank's legal digital currency uses blockchain technology and has the characteristics of decentralization, the security of using digital currency for transactions will be higher, and the transaction information will be transparent, so the central bank can track the flow of funds, Can effectively combat money laundering and other crimes. When people use the central bank's digital currency, they should abide by all the current cash management regulations
in general, the legal digital currency issued by the central bank is not an investment type digital currency similar to bitcoin, so there is no problem of purchasing the central bank's digital currency for investment
this answer is provided by KangBo finance and economics. KangBo finance and economics focuses on the interpretation of financial hot events and the popularization of financial knowledge. It adheres to the profession and pursues fun. It is a financial content that people can understand and transmits financial value in a variety of vivid ways. I hope this answer will help you.
