When bitcoin nodes connect with each other, they will get transactions they don't have from each other. But because bitcoin has accumulated a large number of transactions for a long time, it is very difficult for two nodes to compare which transactions you are missing / which transactions I am missing one by one

to solve this problem, Nakamoto Tsung invented the important technology of block chain. Nodes use blocks to synchronize transactions, which ensures the data consistency of all nodes, and ensures the uniqueness of the blockchain by competing for block packing rights (that is, mining)

① a block and blockchain
a packet formed by a transaction over a period of time is called a block. On average, bitcoin generates a block every 10 minutes, and each block is linked to the previous block to form a blockchain

② the transaction data is synchronized with the block as a unit
the block is numbered from 1, so after node a connects with node B, it is convenient to synchronize the transaction data as long as the block number height of both parties is checked. For example, if node A's own block height is 100 and node B's block height is 110, all it needs to do is request B to synchronize the 10 blocks 101-110<

③ reward for packed blocks
in order to ensure that there are nodes to pack bitcoin transactions, bitcoin rules stipulate that nodes of packed transactions will receive bitcoin as reward
A. part of the package reward comes from the transaction fee paid by the transaction creator (100-1000 transaction fee per KB)
B. the other part comes from the initial distribution of 21 million bitcoins. At the beginning, the reward is 50 bitcoins for each block. After that, the reward will be halved for every 210000 blocks (about four years). Until about 2140, the reward for each block is less than 1, and the total reward for each block is 21 million bitcoins, This is the source of the total amount of 21 million bitcoins (2099999.97690000 to be exact)
after 2140, the package reward will only come from the transaction fee paid by the transaction creator<

④ competition for block packing right
node packing transaction only needs to consume very low-cost network and computing resources. The existence of packing reward (at present, the packing reward for each block is 25 bitcoin, about 40000 yuan), makes a large number of nodes want to pack transactions. In order to ensure the uniqueness of the blockchain, bitcoin rules stipulate that nodes use a method similar to "coin tossing" to compete for the right of transaction packaging. Nodes constantly toss coins. Whoever first throws the results that meet the rules will get the right to pack the transaction in this block, as well as the package reward of this block

Namo, three water to a unitary, well-known as wine, hey. Du Kang's old son brewed a magic pot, which was full of pride and palatability. Without it, Li Bai and Du Fu's poems would be few. Who is it? Namo, three water to a unitary, three meals a day, nothing to ask for, but not a lack of wine every day, ah Hoo hey.

Among the new forces, Xiaopeng automobile is a good one, especially the Xiaopeng P7, which has been popular recently. This is also because Xiaopeng P7 was launched on April 27. Xiaopeng P7 started as an intelligent proct. Xiaopeng P7 is an intelligent electric vehicle targeting young people. In the current instry, the intelligent level of Xiaopeng P7 is relatively high, which can realize L3 level automatic driving scene experience, including full-automatic high-speed navigation,

L3 level automatic driving assistance. At present, it is relatively rare in China, generally L2 or l2.5, Don't underestimate l2.5 to L3, which is more difficult than you can imagine. It needs accurate algorithms to ensure no accidents. At the same time, xpilot 3.0 on Xiaopeng P7 is also equipped with powerful dedicated hardware, the core of which is drive Xavier from NVIDIA. Xiaopeng P7 is equipped with a Tegra Xavier CPU and a Volta igpu with 512 CUDA core. Its computing power can reach 30 tflops with int8 precision, that is, it can realize 30 trillion operations per second. It can be said that it is another "supercomputing" in the vehicle safety chip. The data change is achieved by overcoming numerous difficulties in the research and development process, It's not just cold numbers. Xiaopeng P7's perception system is mainly based on visual perception and supplemented by a variety of sensors. At present, Xiaopeng P7's perception system is richer and more complex than Tesla's, but the actual operation still needs to wait for the field experience to be clear

4. It's illegal to use platform loopholes for arbitrage, of course. It must be illegal. If he doesn't lend money out of arbitrage, he has to pay a fee to lend money. First of all, you can report the earthquake to the Public Security Bureau, and you can find some reporters to expose him

Bitcoin mining machine is the computer used to earn bitcoin

mining software is the algorithm of bitcoin

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 specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

extended data:

bitcoin has the following six characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Worldwide 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

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. 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

5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

6. Although the salary of mining is high, it's very hard

7. Mining is the most primitive "exploration method" to obtain digital currency. In essence, it is to solve a complex mathematical problem with computer. If blockchain is compared to a large account book, the block in which is a page in the account book, and all miners are bookkeepers, the process of mining is bookkeeping, and also to maintain the normal operation of the whole network
the process of mining is very simple. Take bitcoin as an example. Every 10 minutes, all the miners work out a math problem together. Whoever works out the answer first is equivalent to digging this block and getting the corresponding bitcoin as a reward. Mining equipment is the first to use computers. With the rising price of bitcoin, more and more people participate in mining. CPU mining has graally turned into a professional graphics card. In recent years, it has become a specific mining machine. This evolution is e to the problem of computing power. As I said just now, mining means "all miners work out a mathematical problem together." the higher the computing power, the stronger the hardware computing power and the faster the speed. Suppose that the computing power of the computer is 1, the computing power of the graphics card is 5, and the computing power of the mining machine is 100, then the mining efficiency of the mining machine is 100 times that of the computer, It's almost impossible for computers and mining machines to dig bitcoin together

warm tips: investment has risks, so we should be cautious in choosing. According to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have monetary attributes such as legal compensation and compulsion, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
