The concept of bitcoin was founded by Nakamoto
On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank
In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the InternetWhen bitcoin first appeared in 2009, its price was less than 1 cent. One dollar could be converted into 1300 bitcoins, that is to say, seven yuan could be converted into 1300 bitcoins. On May 5, 2017, bitfinex, an overseas digital currency trading platform, quoted a price. Bitcoin once hit US $1700, or about RMB 11737
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all 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 the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

transaction method
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 doesn't need to exchange information online, so it can be offline. There are a lot of bitcoin addresses available
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 is used to record how much bitcoin is stored in the address. You can generate bitcoin address to store bitcoin at will. When each bitcoin address is generated, a corresponding private key of the address will be generated
this private key can prove ownership of the bitcoin at the address. The bitcoin address can be simply understood as the bank card number, and the private key of the address can be understood 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 the address and private key when using bitcoin wallet

Bitcoin is just like the currency in the game, but no one releases bitcoin. Instead, it relies on a specific algorithm to generate , so now people looking for bitcoin also call themselves miners, but they rely on computers to mine
the rise of bitcoin is e to the restructuring of global risk assets , and the widening of investment channels for encrypted assets . Since the beginning of this year, the volatility of securities and foreign exchange markets has intensified, and global investors are looking for safe assets. Traditional safe asset gold is more dependent on the real economy and inflation expectations, Bitcoin is more like a sensitive index, gaining a certain asset hedging advantage
at present, there are two most famous bitcoin miners in the world: ant miner of bitcoin mainland and Avalon miner of Zhang Nangeng. The latter is also the inventor of the first ASIC chip miner in the world
when choosing mining machines, we should first look at computing power, second look at power consumption, and third look at historical reputation
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of mainstream bitcoin mining machines is 14T, that is, 14 * 10 ^ 13C hash collisions per second
power consumption is an indicator of power consumption when the mining machine is running, which is directly related to the cost of mining. Under normal circumstances, the mining machine will operate 24 hours a day, so even if the power consumption of different types of mining machine is very small, the power cost gap is very large
the historical reputation represents the stability of the miner's operation. You can know the overall user evaluation, after-sales service and whether the prepayment miner can deliver on time from different purchase channels
to say that the simplest way is to directly select the latest spot miner model. Because the latest mining machine power consumption will be relatively small, computing power is relatively high, input-output ratio is the most cost-effective
we need to remind you that the noise of the miner is relatively loud, which is also a tough injury of the miner.
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

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.

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
This is a Linux system IP address configuration command. The specific meaning is:
set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0
all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers
The IP address is just like our home address. If you want to write to a person, you need to know his or her address so that the postman can deliver the letter. A computer sending information is like a postman. It must know the only "home address" to avoid sending the letter to the wrong person. But our address is expressed in words, the address of the computer is expressed in binary numbers eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system
On April 18, it was reported that the price of bitcoin had soared for a time, once exceeding US $64000. Today, bitcoin suddenly plummeted, once falling by more than 15%, the price fell below US $52000 / piece
for the sudden collapse of bitcoin, some analysts in the instry believe that it may be affected by the latest news that the US Treasury Department has accused several financial institutions of using cryptocurrency to launder money
affected by the sharp fall of bitcoin, other digital currencies have declined to varying degrees. Ethereum plummeted 20%, coin an plummeted 17%, reborn plummeted 26%, and even Musk's favorite dog coin plummeted 19%
extended data
experts said that the slump is a normal phenomenon:
"in fact, the slump of bitcoin is just a normal phenomenon in the market." First of all, bitcoin itself is a kind of high-risk emerging asset, and its daily price fluctuates a lot, and it is often prone to sudden rise and fall, Li William, chief researcher of Ouyi okex Research Institute, told reporters. Secondly, from an empirical point of view, the withdrawal in the bitcoin bull market is about 33% - 66% of the basic trend direction, lasting for a week or several weeks
according to him, even though bitcoin has entered a bull market since January 2021, with a cumulative increase of nearly 2 times, it often falls sharply, with the biggest daily drop of more than $5000 for at least 7 days, and the biggest daily drop of more than $10000 for two consecutive days on February 22 and February 23
William Lee further said, "from the fundamental point of view, this round of bitcoin slump also has regulatory impact. On Friday, Turkey's central bank banned the use of cryptocurrency and cryptoassets for payments, citing possible "irreparable" damage and trading risks. Shortly after the news, bitcoin fell about 4%. For investors who have entered the market early and hold a large number of bitcoin chips, they have made a lot of profits at this time. In the case of unclear supervision in the future, it may be the best time to choose to sell bitcoin and leave the market, which triggered a subsequent slump. "
