1. If you buy a miner, you can go to digyi
mining to have a look. I bought one a few days ago, which has high calculation power.
2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.
3. Babbitt has a bitcoin mining income analysis article, which has a figure for reference. According to its calculation, it's 132 days
4. The ant S9 proced by bitmainland is the most mainstream mining machine on the market, which is famous for its low power consumption and high output. Ant mining machine S9 adopts TSMC's 16 nanometer FinFET process. TSMC comes from the agent factory of iPhone chip, and ant also applies the full custom design scheme on S9. So, this makes S9 have super
computing power upgrade, let mining efficiency is higher. S9 adopts the latest generation chip bm1387 (189 chips in total), and the computing power of a single chip reaches 74gh / S. in terms of power consumption, S9 maintains at 0.08w/gh/s. (the power consumption is 0.08w/gh/s at 0.4V core voltage, and the power consumption per T computing power wall is only 100W, which is only 2.4 kwh per day. Rated calculation force: 13.5th/s ± 5%
Xuebao miner A1, miner chip is the core of miner. It is said that bitmine is the source of the whole bitcoin miner instry. Bitmine has its own powerful chip technology as early as the end of 2013. Of course, it also benefits from the joint cooperation and efforts of bitmine and other companies, and Xuebao miner is their own proct. A1 is the world's first customized mining machine, equipped with ASIC chip (bf16btc), the number of chips is as high as 576pcs, the computing power of a single chip is 84.1gh/s, and the overall computing power is as high as 49th / s ± 5%
Z4 adopts Intel al core
[email protected] Cup, mining power is 265mh / S (ETH), equipped with independent graphics card 570x8, has 9 fans, and the radiator adopts Intel original radiator, power supply: station flag 2000W power supply, voltage: 12.4-12.6v.
5. Not long after I started mining, I only used one kind of miner, gym intelligent miner, which was recommended by my friend. He has been mining for a long time and said that the indicators of this miner are perfect, and the computing power of gym titanium crystal chip can absolutely keep up.
6. 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
7. There is a daily normal maintenance cost. Otherwise, people can't drink from the north to the West. No, but this is absolutely normal,
8. A lot of them, because their mining machine operation is really stable, and they are more reliable than many platforms in terms of revenue.. If there's anything you don't understand, ask me again
9. On the whole, it's OK. The technical support of Chia mining machine power area of chi'a Shensuan brand is very strong
