What is the ecological certificate of mine pool

1.

mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion

bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."

Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation before

since miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners

further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining

but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China

whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem

2. The four technology pools are mainly used to dig bitcoin, so we all compare the place where we can get bitcoin to the bitcoin pool.

3. Microservice architecture is a new technology to deploy applications and services in the cloud. Most of the debates about microservices focus on whether containers or other technologies can implement microservices well, and red hat said that API should be the focus
microservices can run in their own programs and communicate with HTTP API through lightweight devices. The key is that the service can run in its own program. Through this, we can distinguish service exposure from microservice architecture (distributing an API in an existing system). In service exposure, many services can be restricted by internal independent processes. If any of these services need to add some function, the scope of the process must be narrowed down. In the microservice architecture, only the required functions need to be added to a specific service without affecting the overall process architecture.

4. Xingke has the world's first digital asset research and evaluation system, and has been deeply engaged in digital asset related services for many years.

Through a series of security technologies such as real name security, Google al authentication, wallet hot and cold isolation, it ensures the safety of users' assets, thus attracting a large number of loyal users.

5. We can not only dig filecoin, but also other currencies of the same model, and serve the Internet Ecology as nodes.

7. 1、 It is suggested that the operation of enterprises should be truthfully reflected and accounted to avoid tax related risks< At present, the sales and transportation voucher of mineral procts has not been directly linked with the tax system.

Effective, electronic invoice only need to print out can be reimbursed. The drawer and the drawee can print the format document of the electronic invoice on their own paper (either color or black and white).

The invoice number adopts the national unified code, adopts the unified anti-counterfeiting technology, and is distributed to the merchants. The electronic invoice is attached with the signature mechanism of the electronic tax bureau

the feature that electronic invoice can be printed repeatedly also makes how to prevent repeated reimbursement a problem faced by enterprise financial personnel. The financial personnel as like as two peas have done the tests. The same electronic invoice is almost identical to the original invoice after plication.

" As consumers print by themselves, there will be differences in paper and printing effect, which is equivalent to canceling the physical anti-counterfeiting performance of the original invoice. The responsibility of identifying the authenticity is all transferred to the financial personnel. This responsibility is really too big& quot;

some financial personnel of enterprises say that they usually advise employees to choose the businesses that issue ordinary invoices as much as possible for consumption, but more and more businesses only provide electronic invoices, which often lead to differences between employees and financial personnel
