Knowledge about bitcoin

1.

The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar

< H2 > extended information:

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

starting from the essence of bitcoin, the essence of bitcoin is actually a 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

many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin

2. 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 a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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 money 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

3. So far, no institution can consult bitcoin. Besides, bitcoin is no longer available to indivials.

4. You can negotiate with each other and use it in turn!

5. Do you have QQ
if the thing that proces bitcoin is analogous to a software, such as QQ, then bitcoin is QB. The only difference is that QB is controllable, and there are as many Tencent as you want. Bitcoin is uncontrollable and the total amount is fixed. The more you dig, the less you dig. This is why bitcoin is more and more valuable than bitcoin. What bitcoin and QB have in common is that they are both virtual currencies
if you can't understand it, you can call the one that proces bitcoin gold mine, and bitcoin is the gold in the gold mine.

6. After the face-to-face signature is successful, the review status will be updated in 2 working days. After the review, the card printing and mailing will take 3 working days, and you can receive it in about 10 days. During the mailing period, there will be a short message notice, and you can check the sending situation by the following ways:
first, the postal website (mail tracking query system), which is dedicated to checking the registered credit of the postal service.

second CCB wechat, China Construction Bank, select "application for card / progress query" in "credit card" tab

Third, CCB mobile banking, select "card mailing progress query" in "I want to do card" in "credit card"

7. New people to buy money must choose, simple operation

8. Don't use the computer to dig. Now it's almost impossible to dig. It costs electricity and damages the computer. In addition, the computing power of GPU and CPU is not at the same level. The GPU is too high.

9. The concept of virtual currency bitcoin was first proposed by Satoshi Nakamoto in 2009. Bitcoin is also used to refer to bitcoin's open source software designed and released according to Nakamoto's ideas and its P2P network. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses the ownership of the bitcoin.

10. Bitcoin knowledge and bitcoin system you don't need to know too much, just know a little bit, just like you don't understand Alipay's run away, but most people will use Alipay. Bitcoin home has some news about bitcoin

bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system

bitcoin is proced by mining. Mining is the process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
