Service charge for blockchain bookkeeping

2. That's a good question. Let me give you an example. For example, when I deposit 100 yuan in the bank, the data of this deposit is only recorded in the bank's database, which can't be obtained by others, namely "central bookkeeping". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data does not exist in a center, but is stored once on the computer of the whole network. For example, if I transfer 100 yuan to you, I will shout to all the computers in the whole network. Let's record the accounts together, that is, "Distributed Accounting".

3. The transaction fee will be dected from your total transaction amount. If BTC assets are acquired after the transaction, BTC transaction fee will be paid; On the contrary, if the digital assets are acquired after the transaction, the transaction fee of digital assets will be paid

if you sell 10eth with 1btc, 0.2% eth Commission will be dected, and 9.98eth will be obtained from the sale
if you buy 1btc with 10eth, you will get 0.998btc by decting 0.2% BTC handling charge.

4. bitcoin transfer fee is a fee paid by traders to miners, which is used to encourage miners to compete for bookkeeping and provide enough computing power for bitcoin, so as to ensure the security of bitcoin network. In some places, it is also called miners' fee
when users initiate a transfer in bitcoin network, they usually need to pay a certain transfer fee to the bookkeeper. The transfer service charge is generally 0.001-0.0015 bitcoins. Due to the limited capacity of the block to hold transaction records, miners will give priority to the transaction with high service charge, so the overpaid service charge can be recorded faster
the existence of bitcoin transaction fees can improve the transfer threshold, effectively prevent the blockchain from being full of junk information, and ensure that the miners still have the motivation to maintain the bitcoin network after bitcoin is g up.

5. Blockchain is a decentralized distributed record book and a credit data system. Its advantages are obvious
1. What the Internet changes is the acquisition and transmission of information, while what blockchain does is the transmission of value
for example, on the Internet, we can easily and quickly generate information and it to any place. All information can be spread efficiently, but some valuable information that can only be transferred but cannot be shared often needs credit endorsement
for example, we can't the payment directly to the other party, but we need to subtract some money from the payment account and add some money to the collection account to complete the payment process. The current Internet protocol does not support the function of value transfer. The current value transfer is not direct transmission. Instead, it is endorsed by a centralized third party, such as Alipay, such as banks.
now these centralized organizations put all the calculation of value transfer in a centralized server, which will certainly involve the participation of people, which will cause many problems, such as some "finite theory" and "opportunistic behavior", which will make the whole behavior less credible. So there is a basic question, how to reach a credit consensus
this is how blockchain technology came into being. It can be said that blockchain can build a pure point-to-point value transfer system. Without the mutual trust of each node, blockchain can ensure the integrity and security of data records in the system, and can be separated from the endorsement of third-party organizations, effectively recing the complexity and risk of transactions
2. It is open and transparent, and can not be tampered with
all data of the blockchain can not be tampered with or deleted, and the information of the whole system is open and transparent. If someone owes you a sum of money, and now the data has been put on the blockchain, if he doesn't want to return it to you and play a rogue with you, you can go to the court to protect your rights through the data forensics on the blockchain, so as to get back your legitimate funds. Because the data on the blockchain is open to the whole network, the users of the whole network will know his rogue behavior, which will greatly increase his credit cost. Dishonesty will make him have an important impact in the next life.

7. It's not just the pyramid selling that you said. In the current social environment, there are actually many organizations suspected of pyramid selling, and their operation is very hidden and can run for many years. The main thing is that it's not so easy to remove such organizations, it takes a lot of energy to investigate, and it often takes a lot of time and energy, In the end, only one part of it was removed, so it makes many people seem that the government does not care about this matter. In fact, the government does not care about it, but does not blame the public. Some things are not so simple

8. Bank of China can conct foreign exchange trading. You can open an account at the branch

it's convenient to buy and sell on the phone and online

9. 1. By judging the length of the file, request the length of the file from the server, and then download it back for comparison
2. The best thing is to verify the MD5 code of the file. The server needs to send an MD5 code of the downloaded file to match with the MD5 code of the local file.

10. There are many digital currency trading platforms. Generally, I would recommend okex, and the transaction fee is only 0.1%. If you are going to invest for a long time or have a large amount of money, you can put the money in a cold wallet, which is safer than the exchange. If you don't understand, you can ask me directly
