Why bitcoin computing power

1. From the user's point of view, bitcoin is a mobile application or computer program, which can provide a personal bitcoin wallet with which users can pay and receive bitcoin. This is how bitcoin works for most users

behind the scenes, the entire bitcoin network shares a public ledger called "blockchain.". This general ledger contains every transaction processed, so that the user's computer can verify the validity of each transaction. The authenticity of each transaction is protected by the electronic signature corresponding to the sending address, which enables users to have complete control over the bitcoin transferred out from their own bitcoin address. In addition, anyone can use the computing power of specialized hardware to process transactions and get a bitcoin reward for it. This service is often referred to as "mining."

bitcoin mining has gone through three stages of development. When bitcoin was just born, the price of bitcoin was very low. People just took bitcoin as a game and used their ordinary computers to mine. However, in 2012, with the rise of bitcoin price, people found that the mining speed of graphics cards was fast, so, People began to buy a large number of graphics cards and assemble them for mining, commonly known as "burning graphics cards"; The third stage is the well-known ASIC miner mining. Since Avalon proced the world's first ASIC bitcoin miner, bitcoin mining has been completely subverted, and mining has become a special professional thing.

2. 1. It's bitcoin itself. This calculation process is the issue process of bitcoin. 2. For the above reasons, I think it can be understood as having no practical significance. 3. Are you talking about the number of money packages? That is the number of other clients you connect to (P2P after all), which is very important! This value must reach a certain level before the account can operate normally. Just keep it on.

renrenfu financial and business school tells you that every bitcoin node will collect all unconfirmed transactions and gather them into a data block, which will be integrated with the previous data block. The miner node will attach a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node keeps trying again and again until it finds the random adjustment number so that the generated hash value is lower than a specific target

because hash operation is irreversible, it is very difficult to find the required random adjustment number, which requires a continuous trial and error process that can predict the total number. At this time, the workload proof mechanism will play a role. When a node finds a satisfactory solution, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it meets the specification. If other nodes do meet the requirements by calculating the hash value, then the data block is valid, and other nodes will accept the data block and attach it to their own chain

bitcoin mining uses SHA-256 hash value operation. This algorithm will carry out a large number of 32-bit integer circular right shift operations

exhaustive verification until it finds a data that meets the requirements. This meaningless data is a dollar

4. Is there only bitcoin in Jifu? Bitcoin can't mention bank card. Need to sell first, get RMB, and then mention the bank card.

5. Hello, the total amount of bitcoin is composed of a series of complex codes generated by the computer, and the new bitcoin is made by preset programs

that is to say, when bitcoin was invented, there was a set of mechanism that set so many artificial rules.

6. No, bitcoin is generated by P2P nodes. The reason why it is calculated is that it uses cryptography instead of being generated casually. Because P2P is limited, so the number will not be very large, the operation is not created, but found.

7. Computing doesn't proce any value. It's just that some people use bitcoin to launder money. Only useful things have value. The function of bitcoin is to launder money. Once this function is blocked, it's worthless.

8. In order to dig bitcoin, hardware needs to have very strong parallel data processing capacity and large bandwidth storage capacity. CPU belongs to traditional serial computing processing equipment, and its computing capacity is far less than that of GPU. Moreover, the cache capacity of CPU is far less than that of GPU. Therefore, it is more appropriate to dig this kind of virtual currency with GPU than with CPU

9. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Bitcoin is not issued by 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. 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. Bitcoin is a kind of network virtual currency with limited quantity, similar to Tencent's q-coin, but can be used for cash: it can be converted into the currency of most countries. 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 has no more than 10.5 million in the first four years, and the total number after that will be permanently limited to 21 million. Another point is that you can use computers to make bitcoin
