bitcoin wallet is a kind of software complying with bitcoin network protocol, which can be used to store, send and receive bitcoin< There are three types of bitcoin wallets:
bitcoin client wallets, bitcoin web wallets, bitcoin mobile phones and pad wallets
5. First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. The form of the address is the form
with the bitcoin address generated in the bitcoin wallet, you can receive bitcoin from others, and you can also transfer the bitcoin in your account to the bitcoin address of others. Bitcoin address, like bank card number, has the functions of payment, transfer and withdrawal. However, when transferring money, you can only transfer money by knowing someone else's bitcoin address
if we simply compare a bitcoin wallet to a bank card account, then the address of the bitcoin wallet can be regarded as a bank card account number. The difference is that bitcoin addresses can not be stored on the network, but also exist independently of your wallet
< H2 > extended data:
bitcoin address is a string of 26 to 34 letters and numbers. It looks like a lot of messy code. To put it bluntly, it's just like your bank card number. All transfer records of each bitcoin address can be checked through blockchain query, which is open and transparent
address generation of bitcoin Wallet: 256 binary digits are randomly selected to form the private key, and then the address is generated by encryption function. This generation direction is unidirectional. That is, you know that the address cannot be decrypted to calculate the private key. At present, the computing power of human computer can't be cracked, so you can publish the address on the Internet with ease

6. Bitcoin is a
virtual currency, the world's general cryptocurrency. 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. But it's going to close soon. Bitcoin is a decentralized and open source
digital currency, which will eventually reach a fixed unit of quantity: 21 million, which will not be reached before 2140. The current rate of money proction is 25 new bitcoins per 10 minutes, and the number will slowly decline. It will be halved in 2017, and then it will be halved every four years until it reaches the upper limit. Now who are the people who get those bitcoins that are proced every 10 minutes? It's a technical process, which is essentially to solve difficult mathematical problems, and hard systematic work will be rewarded. In short,
mining is a process of running a program, which helps to verify transactions on the network. Unlike other transactions, it is completed by solving difficult mathematical problems. This special process also leads to its becoming a kind of free currency. Every few minutes, a new bitcoin finds a miner, so that they can protect themselves. Now mining is becoming more and more difficult. Under the leverage of market economy principle, their prices will be higher and higher. If the utilization rate is higher and higher, the prices will be higher. Using bitcoin, you can buy goods and services, convert them into real currency at any time according to the bitcoin exchange rate at that time, and sell bitcoin to other users. If you want to join the mining team, the early hardware and power costs are inevitable, so you can try various hardware settings and calculate its mining efficiency. Risk the price fluctuation of bitcoin is its biggest risk, because the whole market value has reached 1 billion US dollars, many people are eyeing this market. Last month, the value of a bitcoin rose from $30 to a peak of $75; But in 2011, the exchange rate of US dollar to bitcoin fell from US $33 to US $2.51, and it took a long time to recover. Now its transaction value is 125 dollars, so it is very valuable. Instawallet was closed as a bitcoin hosted wallet on Thursday because of the attack, and it indicates that 90 days later, if no one else claims to have received the same URL, users under 50 bitcoins will recover 50 bitcoins. For indivials, if you pay attention to privacy, want to trade a small amount of money without government regulation, and have a wallet that can be entrusted with the custody of bitcoin, you can have a try. There is still a long way to go before it can replace the existing currency. The infrastructure under it needs to be well constructed to be generally accepted. If you want to buy one or two in the near future, it is absolutely no problem.
7. First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. As long as the address is generated by your client and other people pay to the address, they will remit money to the wallet. Where is your wallet? If you are using the Windows client, please click the start menu, find "run", and then enter% appdata% &; Bitcoin click "OK" and you will find a file called wallet.dat, which is your "wallet". The wallet stores all the keys used to prove that you have the money contained in the wallet. You need to do two aspects of work at the same time: 1. Ensure that the wallet will not be lost; 2. Ensure that the wallet will not be obtained by others. The method is: encrypt the backup. Relatively simple and effective one is: 0, install anti-virus software, thoroughly kill a virus, keep anti-virus software running 1, close bitcoin client 2, use winrar encryption compression. Please remember to use the password with enough security, and the password should not be retarded. Then back up the encrypted file to a secure U disk. 3. Delete the wallet.dat in disk C. when you need to pay bitcoin, 4. Is it troublesome to decompress the backup wallet.dat into the folder mentioned above? Yes, it's so troublesome, because bitcoin currency system is still at an extremely early stage. It's invented and accepted by some technology enthusiasts, and they haven't had time to take care of the feelings of ordinary users. All of this will become easier to use in the future. However, the next version of bitcoin client is ready to build in the integrated wallet encryption function, which will be much easier for ordinary users to back up. As long as you make sure that your computer has no Trojan horse and set a strong enough password, it is largely safe. Gavin also plans to introce a two device authentication mechanism, that is, to divide your wallet into two parts that are encrypted and protected, one part in your computer, and the other part in other devices, such as mobile phones. Just like the SMS verification launched by some online banks, to complete the payment, two devices need to confirm at the same time. This is not troublesome for the actual owner of bitcoin, but for the thieves, they need to steal the files of two devices at the same time to steal the key. In addition to the acquaintances around you (you must also know your password), that is basically an impossible task. It is expected that there will be reliable bitcoin online storage in the future, and even traditional banks may launch bitcoin escrow service, which will be much more convenient at that time
