Can Tianhe supercomputing dig bitcoin

1. I tell you, the computing power of home PC is too low. According to the difficulty of more than 900 million computing and programming, the computing power of a home PC is generally between 100 m and 600 m. if you dig, the money you earn in a month is not even one tenth of the electricity bill, so you need a mining machine. Now on the market, the machine specially optimized for the calculation algorithm of the generation of bitcoin is the miner. A miner can process 600ghash data operations per second. Without interruption, it can generate a bitcoin in about 10 days, which requires high computer configuration

it's not impossible that you can dig 100 in a day. To be exact, it doesn't take a day. It only takes less than a few seconds to win. The premise is that you can win "Tianhe No.2" which ranks first in the world.

No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

DCC lending chain is not MLM, the specific analysis is as follows:

1. DCC lending chain is a smart lending contract proct based on blockchain technology, which is launched by famous Japanese financial experts and Japanese domestic financial companies. The purpose of loan chain is to give intangible digital assets the same status as real estate, and to carry out mortgage short-term lending and financing lending within the controllable range of value

Second, MLM refers to the illegal act of organizers' development personnel to obtain wealth by developing personnel or requiring the personnel to be developed to obtain the qualification to join in on the condition of paying certain fees. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comers

the new type of MLM: it does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take big classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money, drives luxury cars, wears gold and silver, and uses money to attract your relatives and friends to join, and finally makes you lose all your money

extended data:

Network loan risk

1. The virtuality of network transaction leads to the inability to authenticate the credit status of both sides of the loan, which is prone to fraud and default disputes

2. Among the large amount of information about lenders released by the network platform, many of them issued loans in the name of "loan company" and "financing company". In fact, only financial institutions approved by the state can engage in financial services such as credit financing. Those who engage in financial activities without authorization will be investigated for legal responsibility for "illegal fund-raising" and "illegal attraction of public deposits" and disturbing the order of financial management

3. If the loan is issued on behalf of the network platform, then the network platform is lax in self-discipline, or the internal control proceres are invalid, or it is used by others, then the situation of fabricating loan information and illegal fund-raising may occur

4. Bitcoin is a kind of P2P digital currency. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. 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 currency 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.

5. There is no doubt that it can be surpassed. Although tianhe-2 has super computing power, it is not specially used for bitcoin mining. Bitcoin ASIC miner is specially designed for bitcoin algorithm, with strong computing power. Some netizens calculated a sum of money, and converted the computing power of tianhe-2 into mining efficiency. About two to three bitcoins can be g out in an hour, which is 15000 yuan. That's 360000 yuan a day. Mayor Chen Jianhua said that tianhe-2's daily electricity bill is 300000 yuan, which seems to make a little money. However, if labor costs, depreciation of machinery and other costs are taken into account, "mining" will not make much money. This is the result of last year's calculation. According to the current difficulty of mining, the profit is much less than this

at present, bitcoin mining is a very professional business, which has graally developed into an intensive large mine. The upgrading of bitcoin miner is very fast. Take Avalon miner, the mainstream miner in the market, as an example. At present, three generations of chips have been upgraded, and the fourth generation is expected to come out soon. In the future, it can be predicted that mining will graally move towards concentration, retail investors will graally disappear, and mining will have a large-scale effect.

6. This is last year's news: some netizens calculated a sum of money, and converted the computing power of tianhe-2 into mining efficiency. About two to three bitcoins can be g out in an hour, which is 15000 yuan. That's 360000 yuan a day. Mayor Chen Jianhua said that tianhe-2's daily electricity bill is 300000 yuan, which seems to make a little money. However, if labor costs, depreciation of machinery and other costs are taken into account, "mining" will not make much money

this is the data provided in a press release at the end of November last year. Of course, according to the current computing power, we can't dig so many bitcoins, and the revenue will be lower. Even tianhe-2 mining is a loss

after all, bitcoin mining is a professional business, it needs a professional bitcoin miner. And the update speed of bitcoin miner is amazing. Take the mainstream Avalon mining machine in the market as an example, it has been upgraded to three generations of chips, and the fourth generation will come out soon.

7. Supercomputer has strong computing power because it can not be measured by an ordinary computer, because it is a cluster of computers

supercomputing chip is different from mining machine chip. If we say that the comprehensive operation efficiency is certainly high, but the instructions of supercomputing chip are very complex, and mining machine chip is optimized to only execute bitcoin operation instructions. It costs a lot of electricity, and its efficiency is not as high as mine machinery
supercomputers are not suitable for bitcoin mining. Bitcoin mining machines are loaded with a lot of graphics cards, suitable for large-scale parallel computing, mining efficiency is very high. But supercomputers are different! Supercomputers are not designed for mining, which is less efficient than bitcoin. If we want to compare the computing power of global mines, we need to pay more, which is obviously not cost-effective
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

8. Hehe, the idea is naive. The problem is very simple. At present, the network speed of bitcoin is 1861 petaflops. Tianhe two is 33 PETA flops
less than 2%<

the output of the whole network is about 150 per hour, and Tianhe can dig about 2 BTCs per hour, which is about $200
its power consumption is 24kw. Fifty cents per hour of electricity is 12000 yuan, or two thousand dollars

spend $2000 to generate $200. That's the effect The actual depreciation cost is probably higher than the electricity charge)

9. Well, it must be dominant, but it's just killing ants with a bull's knife
it is said that the cost of tianhe-2 is 2.5 billion yuan, and it is estimated that it will cost at least 3 billion yuan to buy, while the daily electricity cost of tianhe-2 is about 300000 yuan
there are three billion, three hundred thousand a day. Can't you buy Incense directly???

10. The overall principle is that the stronger the computing power is, the larger the proportion of bitcoin can be allocated. However, the speed of bitcoin generation is graally decreasing

technically speaking, it is completely feasible, because the algorithm is not complex and can be transplanted to the mainframe with a little modification. If it can be optimized for parallel computing, it will be more efficient
but in terms of cost, supercomputers are not cheap to use. Only a medium-sized and large-scale computer consumes tens of thousands of power every day, not counting the loss of the whole machine. As for supercomputers like Tianhe-1 and tianhe-2, the research and development costs and rental costs are still relatively high. Whether the excavated bitcoin can recover the cost still needs to be carefully considered.
