What is the area of the mine with 10000 mining machines

1. The mine is a place for centralized management of mining machinery, which is generally located in a relatively cheap and stable place. In the early days, the operation of the mine was extensive, that is to build a shelf, and then put the mining machine on it, and then it can start to operate. Later found that this mode of operation, mining machine damage rate is high, maintenance costs are too high
later, there were ventilation and st isolation schemes, and later, there were strict control of indoor temperature and humidity. Now the operation scheme of the whole mine is still upgrading and evolving
because the running noise of the mining machine is relatively high, when one mining machine is running, the test noise is about 73db (a) at one meter, and the impact of thousands of mining machines on the surrounding environment can be imagined, so some places have been designed and renovated, and there are silent mines.

2. bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly 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. No radiation, even smaller than some densely populated super cities! It's about power! Electromagnetic wave and electromagnetic radiation are different! Although long-term contact has an impact on the body, standing outside the house basically has no impact!

4. Direct code solution

A: first, block height does not refer to the capacity of the blockchain

Second, the connotation of block height

block height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain

Block height is the indicator of block

2. The block has two identifiers, one is the hash value of the block head, the other is the block height

3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm

The

block hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head

4. Block height refers to the position of the block in the blockchain

The

block height is not a unique identifier

6. Two or three hundred square meters is enough. The power supply should be at least one kilowatt

7. A few days ago, I was called to learn about blockchain, mining machine and so on. They are all pyramid schemes. It is estimated that they are a huge scam. By that time, the company and people will be gone.

8. There is a function called "my wallet" in the wechat mobile phone board. You can click to open it to find "wallet" and "transfer". Then click "wallet" to find "change" and "add bank card". Click "add bank card" to add your bank card to open the payment function.
