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
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

Of course not. The most important thing about bitcoin is its uniqueness

What is the sub address of bitcoin
the wallet of bitcoin is based on the HD (hierarchical certainty) framework, which has the methods of generating different addresses and managing addresses. Each public address of your wallet will be generated from your wallet's xpub (extended public key)
if you use the same address every time you receive a BTC, anyone can easily track all your payment records. This address generation method improves privacy by generating a new address (sub address) when you collect money

public key and private key are terms in asymmetric encryption of modern cryptography. They usually encrypt information with public key and decrypt information with private key. Why? Because when you watch TV dramas, telegrams are encrypted symmetrically. The disadvantages of this encryption method are obvious. If someone knows the key and encryption method, they can decrypt the telegrams according to the encryption method. Until asymmetric encryption, the situation has changed. Public key is the key that can be made public all over the world. For example, when you communicate with Google, you encrypt with the 1024 bit public key given by Google and send it to Google. Only he has the corresponding private key, and only he can decrypt it, so the communication security is ensured
2. Bitcoin mainly uses ECDSA, which is the elliptic curve signature algorithm, This algorithm has two characteristics. Note that these two points are very important to the following
A. as long as you know the private key, you can calculate the corresponding public key
B. If you have signed something with the private key, you can use the public key to calculate whether you signed it or not
3. After knowledge preparation, let's start with the transaction of bitcoin. In fact, bitcoin has no wallet, only transaction bills, and the whole bitcoin is a lot of transaction bills
for example:
bill 1 transfers from a to B to XXX bitcoin
Bill 2 transfers from B to C and D to XXX bitcoin
bill 3 transfers from C to e to XXX bitcoin
.... Anyone who downloads the client can receive all the bills from the day when bitcoin was established, so as long as all the bills are downloaded, they will naturally know how much money should be left on each account (think carefully here)
4. The account of bitcoin is the public key mentioned just now
5, Here is the core part!!! Each bill is a piece of data. After you sign it, it will be sent to the whole network, and the data structure will be reversed into easy to understand Chinese. The explanation is as follows:
from (who sent it, including two parts)
previous TX: the ID of the bill for which you want to spend the money, that is to say, any money you spend should have been transferred to you, You need to show the ID of the bill
scriptsig: your signature for this transaction is to hash the bill with your private key, only you can do this hash
to (who accepts, including two parts)
value: how much to send
scriptpubkey: the public key of the other party, and the bitcoin account is a public key
6, How to send it? Bitcoin communication is not so complicated. You can compare it to IRC channel, but different from ordinary "IRC", any client is an "IRC" server. When you start the client, you will receive the client address with public IP around, that is, the "server" list. This list is constantly refreshed, and it is all other bitcoin users, So when you shout a word in this "IRC", people around you will hear it and spread it all over the world
7. After sending the signature to the whole world, all the clients who receive this list will verify whether your signature is correct, whether you sent it, and whether you have so much money (according to the historical transaction, you can calculate how much money you have to spend)
if you have calculated this transaction, it's OK, Basically, the transfer is successful
8. In fact, the other party has accepted bitcoin, but in order to spend it, he must have the private key corresponding to the address (public key). So he can fill in the from header of a form. Previous TX is the serial number of the transaction just now. Scriptsig fills in the hash signed with his private key...
