It is reported that the performance of bm1385 chip is more than twice that of bm1384
The power supply scheme of S7 is similar to that of S5. The S5 + mode of dense chip arrangement is adopted, which makes the arrangement structure more compact. Under the same space, 60 chips are placed in S5 and 162 chips are placed in S7 The price of S7 is 1823 US dollars, equivalent to 11650 RMB yuan, and the delivery time is from September 21 to September 30. At the same time, the official announced the parameters of ant mining machine S7. The chip adopts bm1385, a 28nm fully customized chip independently developed by bitcontinental, with a computing power of 4.86t and a power consumption of 1201w. Ant miner S7 is the best miner with the best power consumption ratio so far, and the power per T is about 250Wofficial website is not open for sale at the moment. Users of early adopters can place their orders in overseas official website. The delivery address is 17% of the Chinese mainland tax and the purchase price is 13630 yuan. p>

Cryptocurrency is not a tangible currency that can be carried with you, but a digital asset that can be exchanged“ The "encryption" part comes from using encryption technology for security and authentication ring a transaction
when using cryptocurrency for exchange instead of legal tender, crypto owners do not have to rely on banks to facilitate transactions, and can successfully avoid the costs of using financial institutions
generally, cryptocurrency transactions are processed and completed through the blockchain network. The blockchain is designed to be decentralized, so each computer connected to the network must successfully confirm the transaction before it can process it. Ideally, this would create a more secure transaction for all involved. It can also cause you to wait for a while; One of the big complaints about bitcoin is how long it takes to complete the transaction
domestic cryptocurrencies include bitcoin, Ethernet, Leyte and e-dinarcoin
extended data:
bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. It is a P2P form of digital currency. Bitcoin is generated through a large number of calculations according to specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation
ether coin: ether coin (a digital token of Ethereum, regarded as "bitcoin version 2.0"), can be bought and sold on the trading platform
lightcoin: lightcoin is a kind of network currency based on "point-to-point" technology, which can help users pay to anyone in the world immediately. At present, it is the second virtual currency after bitcoin's global circulation market value

the high housing prices destroyed the post-80s and post-90s
and then the world came back. Today's virtual currency
the post-80s also pulled back a round. Whether it is worth buying is not to see whether its current price is high or low
but to see whether it has value in the future and whether it will be useful for everyone's life There must be only a few bitcoins in total.
bitcoin has become a kind of value preservation proct corresponding to gold
decentralized anonymity advantage
bitcoin comparable to gold
moreover, more and more businesses have accepted bitcoin transactions
some institutions have also accepted bitcoin donations, and bitcoin ATM has become a hot topic Put into use
the second is
Ethereum (ETH)
it can be said that it is an evolutionary version of bitcoin
bitcoin is gold, Ethereum is silver
Ethereum's technology can be applied to real world applications
JPMorgan Chase, Microsoft, etc. are all optimistic about Ethereum technology
In my opinion, the most stable return is the twoand the other multifarious currencies have gone up and down sharply. Ordinary people's hearts can't stand
at present, domestic users can buy through this website

it's not the price rise of the currency but the price rise of the currency through the bar The number of coins is rising

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.
System). In this system, the concept of single miner no longer exists, but the concept of mole cluster
taking Avalon 40 nm mole as an example, each mole has 295g computing power. According to the actual situation of the mine site, power supply and heat dissipation, users can freely choose to stack 1-40 moles (corresponding to about 0.3t-12t computing power) into a computing power cluster unit, which can be controlled by one terminal, one network cable and one IP address. Revolutionary technological innovation has raised the flexibility and simplicity of mine layout to an unprecedented level.
Matlab neural network toolbox can be used to extract samples first, normalize them with mapminmax function, then establish the network with newff function, set training parameters, train them with train function, and finally see the prediction results with SIM function
in the process of training, there is a performance that can be observed, and its training goal is the goal you set. In the process of training, it will automatically separate a part of the samples as validation verification, which can ensure the fitting. In order to evaluate the effect, the accuracy of the final prediction should be considered
