What is bitcoin instruction
{rrrrrrr}
bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct
related concepts:
1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address
with the key, you can control the money in the bitcoin address and pay to anyone. The key should be absolutely safe. The lost or deleted key can never be found, and the money in the corresponding bitcoin address can never be used
the key needs to be kept absolutely secret. Anyone who knows the key can steal all your bitcoin
4. Wallet
the transaction process of bitcoin will involve a lot of complex calculations. In order to simplify the operation, we have made wallets. The wallet has client software on the computer, and also has an online web version. The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
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
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. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you 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
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost.
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
currency characteristics
Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: the private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform Mining: users can explore the computing power of different hardware on many platforms.
