Bitcoin is a virtual cryptocurrency based on Internet
1. bitcoin:
also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
2. The origin of bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
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 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 generation principle of bitcoin:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
compared with RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you will have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
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
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items[ 1-2]
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and take action as soon as possible to completely ban the electronic currency[ 3]
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees.
at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions
bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent
bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer

users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold diggers by repeatedly solving riddles to provide the required numbers for bitcoin network. If the user's computer successfully creates a set of numbers
bitcoin is e-cash similar to e-mail. 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
