Is bitcoin useful without miners

1.

Look, you are an expert

bitcoin mining is the most important source of procing bitcoin and the method of obtaining original bitcoin

the mining of bitcoin refers to the process of generating new blocks and calculating random numbers. The simple understanding is that the computer in the bitcoin network constantly collects transaction data and constantly calculates and verifies the process. Once the verification is passed, a block is generated, and each block rewards a certain amount of bitcoin according to certain rules

therefore, in fact, bitcoin trading platform and bitcoin mining are two different concepts, and mining machine still plays a great role

2. can't. Less miners will only lead to less proction. Repeated payment is a bug that bitcoin cannot tolerate

3. We often hear about B2B, B2C, C2C, etc. What does B2B, B2C, C2C market mean? Maybe many friends don't know much about it. Let's introce it separately
1. B2B (also written as BTB, which is the abbreviation of business to business) refers to the business model in which enterprises exchange and transfer data and information and carry out trading activities through private network or Internet. It combines intranet and procts and services with customers through B2B website or mobile client, and provides better services for customers through rapid response of network, so as to promote the business development of enterprises
2. B2C is the abbreviation of business to customer, and its Chinese abbreviation is "business to customer"“ "Business to customer" is a mode of e-commerce, that is, the retail mode of selling procts and services directly to consumers
3. C2C is actually a professional term of e-commerce, which is the e-commerce between indivials. Where C refers to the consumer, because the English word of the consumer is customer (consumer), so it is abbreviated as C, and because the pronunciation of 2 in English is the same as to, so C to C is abbreviated as C2C. C2C is customer (consumer) to customer (consumer). C2C means the e-commerce behavior among consumers. For example, a consumer has a computer, through the network transactions, it sold to another consumer, this type of transaction is called C2C e-commerce
B2B has three treasures: enterprise, intermediary, communication,
B2C has three treasures: brand, channel, sales,
C2C, there are three treasures: you open, I buy, Alipay
above is a brief introction about B2B, B2C, C2C market what is the meaning of this, through the introction of this article, we should have a certain understanding of these models, and hope to help everyone.

4. In theory, at the last moment of bolt tightening, the stress on the bolt reaches the allowable strength of the bolt (determined by the strength level of the bolt (e.g. grade 8.8, when the tensile stress of the bolt is 800N / mm2). The force on the bolt can be calculated according to the diameter of the bolt. According to the diameter of the bolt (take the pitch diameter of the thread) and the pitch of the bolt, the inclined angle of the bolt is obtained; According to the static friction coefficient between the pressure (i.e. the force acting on the bolt) and the material, the thrust can be obtained. The thrust multiplied by half of the pitch diameter of the thread should be equal to the torque of tightening the bolt. The moment divided by the arm length from the point of action of the force to the center of the bolt is the force required on the wrench. Of course, this is not the preload of the bolt.

5. 1. All transactions can't be free of service charge, but the service charge is not given by percentage, so it's quite cheap for block transactions
2. In order to prevent fraud in a transaction, many nodes need to perform operations to verify. In fact, most of these operations are provided by the miners, so the handling charges go to the miners who are mining. Bitcoin will not be reced either

6. No one mines, no one keeps accounts, and no one keeps accounts in vain. Therefore, there should be a reward mechanism for mining. If the bitcoin price returns to zero one day, the reward will not be worth money, and no one will keep accounts

7. Of course, it's useful. Even if bitcoin has been g up, bitcoin network still needs to run normally. Mining is still essential

mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary

8. Useful should be useful, but it seems illegal in China. It's just a virtual commodity. It can't really be used as currency.
