2. Now it's very difficult to download the program from the official website and do it yourself, but it may take several years. The second way is to buy it. Now it's about 18 dollars, less than 100 yuan. Mt.gox, bitcoin's largest trading website. On the official website of bitcoin, there is a paper by Nakamoto Tsung, which details the technical principles of bitcoin. In short, bitcoin is based on a set of cipher codes and generated by complex algorithms; Anyone can download and run bitcoin software to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P network
by 2140, the total number of bitcoins was 21 million. I suggest you buy it< In 2009, a mysterious hacker named Satoshi nakomoto first proposed the concept of bitcoin, and described a method of using computer networks to create an unmanaged "secret currency". Unlike other virtual currencies, bitcoin is not issued by a company or a central bank, nor linked to any real currency, but can be used to buy goods and services in the real world. In essence, it can be seen as a small string of encrypted code quickly transmitted and stored in the electronic wallet on the Internet. Just as the P2P networks such as Napster and Skype once made the record instry and telephone instry into a mess, bitcoin, which challenges the modern monetary and financial science, is also based on P2P - the same as our commonly used BT download technology. The advantage of P2P is to ensure that no institution can manipulate the value of bitcoin or increase the supply to create inflation. In a huge P2P network, bitcoin has a special algorithm, which proces about 300 bitcoins per hour. This output is automatically adjusted by the network. Because you can't control most of the network nodes, you can't modify the algorithm of each user to speed up the money proction. Figuratively speaking, bitcoin is "mined" by computers all over the world. If you want to get bitcoin, you just need to install mining software, and your computer will start to do a lot of calculations, which is mining. No matter which computer is used to mine, it is easy to get 50 bitcoins in the early days of bitcoin. As early as January this year, 50 bitcoin was not worth $15, but on June 9, a bitcoin was worth as much as $29.55. If you trade them, you can get back $1500 of real gold and silver. Now, however, mining requires high-performance computers, and some developers involved say that it is estimated that an ordinary laptop will work for five years to get a bitcoin. Why is that? We have to start with the currency itself. Economics tells us that money exists because of transactions. The value of bitcoin lies in the transaction itself. In order to transfer bitcoin from one account to another, there must be a secure channel. To create a secure channel, a lot of energy will be consumed. Therefore, the whole bitcoin user group should reward the mint (50 bitcoin). In other words, he succeeded in mining. Mining, in essence, is the process of creating new blocks (each block contains 50 bitcoin) on P2P network. In short, the software algorithm determines that it is difficult to create a new block that is recognized by the whole network. If there are more participants, the new block will be generated more slowly. Just like mining, with the depletion of the most accessible resources (assuming no newly discovered mineral deposits), the supply will graally decrease. According to the algorithm, each block can only generate 25 bitcoins by 2013, 12.5 bitcoins by 2017, and so on. By 2030, the total number will stay at a platform, about 21 million. Graphically, this will be a flat curve. Reality also proves this point. As the value of bitcoin rises and the number of participants increases, mining becomes more and more difficult. At the forum, miners discussed how to use dry ice and liquid nitrogen to cool computers, increase CPU frequency and speed up mining software, or customize top computer graphics cards and improve network speed to proce more bitcoin. According to the guardian, someone was mysteriously mining at home, and even was suddenly attacked by the police, who mistook him for drug trafficking. Recently, Symantec, a digital security company, discovered a new trojan virus. This malicious program, coinbit, is used to steal numbers, so that hackers can easily break into users' bitcoin wallets and steal their contents. Before the June 19 incident, members of the lulzsec hacker group and anonymous team had discovered that there was a better way to mine - to use someone else's computer. These hacker groups are famous for their server attacks mainly relying on botnets. Some members found that some miners actually use their botnets to mine. The miners are also said to be hackers, who have used botnets to control more than 100000 computers. With the scale of the current network, the efficiency of mining can be greatly improved. It is estimated that 400 to 500 bitcoins can be proced every day, and the current value is more than 8000 US dollars (as of June 28, 2011, 1 bitcoin = 16.9 US dollars). There are two groups of people in the bitcoin community. One group denies that someone is using botnet to mine. The other group says that this is a fact and admits that botnet computing has dropped dramatically. An anonymous person said it was clear that there were people who thought that participation in mining would be more rewarding than attacking mining.

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

4. 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

Bitcoin core wallet is the most complete and secure wallet on the market, and it is also the earliest bitcoin client. However, e to the huge volume of blockchain data file (blockchain) that needs to be loaded in the proct and slow startup, it will be troublesome for novices to start

bitcoin wallet

a wallet usually has multiple private keys, and many bitcoin investors also have multiple wallets. Wallets can be placed on computers and / or mobile devices, on physical storage devices, or even on paper

e-wallet - e-wallet can be downloaded software or hosted in the cloud. The former is just a format file that exists on your computer or device to facilitate transactions. Hosted (cloud based) wallets usually have a more user-friendly interface, but you will trust a third party with a private key

software Wallet - installing a wallet directly on your computer can provide you with the security of your control key. Most have relatively simple configurations and are free. The disadvantage is that they do require more maintenance in the form of backup. If your computer is stolen or damaged, and your private key is not stored elsewhere, you will lose bitcoin

Mobile Wallet - mobile wallet can be used as an application for smart phones, especially if you want to pay with bitcoin in the store or buy and sell on the road. All of the online wallets mentioned above and most of the desktop wallets have mobile versions, while others (such as Abra, airbitz and bread) are created with mobility in mind

Hardware wallets - hardware wallets are small devices that are sometimes connected to the network for bitcoin transactions. They are very secure because they are usually offline and therefore cannot be hacked. However, they may be stolen or lost along with bitcoin belonging to the stored private key. Some large investors keep their hardware wallets in secure locations, such as bank vaults. Trezor, keepkey and ledger and the case are obvious examples

paper wallets - perhaps the simplest of all wallets, these are all paper with the private key and public key of the bitcoin address printed on it. These wallets are ideal for long-term storage (obviously, away from fire and water) or as a gift of bitcoin, because they are not connected to the network, so they are more secure. However, they are more likely to be lost

with services like walletgenerator, you can easily create new addresses and print your wallet on the printer. Fold, seal, and you're done. Send some bitcoin to the address and store or distribute it safely
