How is digital currency destroyed

1.

digital currency is a new technology that can be used to improve transaction efficiency, but now it has been targeted by some lawless elements and carried out marketing and fraud in its name, using ordinary people's ignorance of digital currency to deceive investment and investors

Generally speaking, we investors or cheated people should prepare the following evidence:

1. The chat records between relevant chat records and analysts or agents or order calling personnel are the most basic evidence, because such evidence can fully reflect the whole process of our cheated people being cheated and the illegal places of relevant business personnel in the chat process, Can be fully reflected in the chat record

2. The evidence of relevant deposit and withdrawal records is the deposit and withdrawal of the bank account of the investor or the cheated person, which can reflect the investment and withdrawal of the cheated person, and the difference between the two is basically the total capital loss of the investor. This kind of evidence can be preserved by the cheated basically, just go to the bank and print the bank account

the above evidence is the basic evidence that investors or cheaters should have, but not all the evidence. In the process of power only, if there is no or incomplete basic evidence, then the difficulty of power only will increase, but the light of justice is still willing to take up the weapon of law to help you safeguard your vital interests! Willing to give the most professional legal aid! Promise only right is not successful, do not charge the slightest fee

2. 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 a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. 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
according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

warm tips: the above information is for reference only. Before investing, it is recommended that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

3. 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

4. Hacker attack
bitcoin can exist only because both sides of the transaction recognize its transaction value, so anyone can design virtual currency independently. Ars technica, for example, announced this week that it would create its own cryptocurrency, arscoin[ 2]

Cohen believes that the main threat to digital cryptocurrency is how to keep it safely, and the loss of mt.gox bitcoin once again highlights this problem. Recently, the US Congress has also launched a debate on digital cryptocurrency. Some members believe that the supervision of the bitcoin should be strengthened to avoid risks. Another congressman, Jared polis, believes that the US dollar has similar defects to bitcoin, so if bitcoin is banned, then the US dollar note should also be banned[ 2]

digital currency has a short history of development in the world, but it develops rapidly. Many countries are trying to sum up experiences and lessons through official or non-governmental efforts.

5. With the support of blockchain technology, build the ecosystem of e-invoice, so that data can be exchanged and shared between third-party platforms, self built platforms, and third-party platforms of e-invoice, and bring real benefits to consumers and enterprises.

6. How much did you put in? Are there any records

7. What do you mean, locked or platform locked? The general platform will not easily lock your account. It is recommended that you do not go to some small platforms casually, which are easy to be cheated. If you choose, you should choose some reliable old platforms with a longer service life, such as AEX and fire coin. You can also directly go to AEX financial supermarket for financial management, and the income will be relatively stable
