Digital currency migration and destruction

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. The answer is yes
when transferring money, the receiver only needs to send the address of the wallet to the other party, and the other party can transfer the digital currency to the address. When trading in the exchange, the user should also enter the digital currency into the address designated by the exchange, that is, the wallet, to complete the transaction. At the time of withdrawal, the exchange will also enter the digital currency into the user's wallet address accordingly. This is how the money should be transferred to the wallet.
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

5. The dealer chooses your wallet address, transfers it to you, and you pay. This is a complete transaction

Bharath Rao, an American entrepreneur, is looking for the best place to trade his cryptocurrency derivatives in order to raise funds, but this address list does not include the United States. Instead, he chose Seychelles, the island of East Africa, to sell the platform's tokens

since the beginning of this year, there are 34 digital currency start-ups registered in the United States, the number of which is ahead of other countries. However, this only reflects the role of Silicon Valley as a global technology center in the United States and the degree of in-depth development of the U.S. financial market, which does not mean that the regulatory level welcomes digital money“ According to the data provided by "Smith + crown", there are 21 digital currency companies registered in Singapore this year, compared with only one last year; The second is Switzerland, with 19 digital currency registered enterprises this year, compared with only three in Switzerland last year; The number of registered companies in Central Europe this year is 14, compared with only one in 2016; There are 10 companies registered in the Caribbean this year, compared with only two last year“ These data confirm our feeling that Switzerland and Singapore are still the first choice, but the US is still likely to raise a lot of money for those companies, "said Matt chwierut, research director at Smith + crown

7. I'm particularly optimistic about okb on the okex bitcoin exchange. This year, the destruction of 70% of the quantity may bring about a 70% increase in the price. The market performance is also more in line with the model results. On February 10, okex announced the destruction of 70% of okb, as well as the launch of okchain online and the start of internal test of okdex. Okb rose 36% on the same day to US $5.37, and rose to the highest US $7.51 in the following days, Up 90%.
8. Matcha is a trading platform. Non trumpet is just a platform to check market information and query trading platform. It should not be transferred. I really don't know that non trumpet can directly trade bitcoin.
