How to calculate the bitcoin node

1. In fact, the mining calculation of bitcoin is to do math problems together. The problem stem is the transaction that needs to be recorded. By doing the problem, everyone grabs the bookkeeping right, and the miners can get system rewards and transaction fees
the feature of sha256 algorithm used in bitcoin is that it's easy to verify the known answers correctly, but it's very troublesome to get the answers, and you need to try them one by one. The miner who got the answer first was recognized by everyone as having snatched the right to keep accounts, and the reward was given to him. Let's continue to grab the bookkeeping right of the next question
simply speaking, the significance of these calculations only lies in ensuring the stability and security of the whole system, and has no more significance. It is not comprehensive to regard bitcoin as a by-proct of computing. The generation and issuance of bitcoin, all the transactions and circulation in the bitcoin chain, and the stability of the bitcoin system are all the purposes of computing. Of course, in addition to maintaining the system, it does not proce other value and procts. This is also a black spot where bitcoin is accused of not being environmentally friendly and wasting resources
in general, bitcoin, as a milestone blockchain digital currency, comes from the huge value of a large amount of computing power investment and user trust. There is no doubt about that.

2. So what are nodes
a node is a network node in the blockchain distributed ledger system. By connecting servers, computers and other devices through the network, different types of blockchains have different ways to become nodes. For example, bitcoin participates in trading and mining, and EOS participates in election campaign to become a node
the following is what is a bitcoin full node
bitcoin full node is the node that downloads and preserves complete blockchain data by loading bitcoin clients (including bitcoin unlimited and bitcoin)
because of the congestion of the blockchain transaction network, the author solves the problem by adjusting the broadcast communication, information encryption and decryption, consensus mechanism and transaction verification mechanism. In the whole bitcoin network, from miners to ordinary users can be regarded as a node in the bitcoin network, but because bitcoin has the characteristics of multi centralization, In the whole network, its important role is "bitcoin all nodes."

3. The bitcoin node is the host that downloads the bitcoin core
bitcoin nodes constitute the bitcoin network and become a member of the network. To be able to trade with other nodes is to verify the transactions on the network (consensus mechanism).

4. The nodes of bitcoin are software running on the computers of millions of bitcoin users, and millions of bitcoin nodes are interconnected to form a bitcoin network. Bitcoin node software usually includes the following functions:
1) wallet. It's used to store your bitcoin balance. In principle, as long as you have the private key of your own bitcoin address, you can use your own bitcoin
2) verify the transaction or payment. After receiving the transaction, the bitcoin node will use certain algorithms to verify the validity of a transaction. If you only change the balance of bitcoin in your computer, others will not recognize it. Similarly, your wallet will not recognize the transaction changed by others
3) mining. Core wallet can start mining function through a command to join the mining army, while SPV wallet usually can't (SPV is just passing by). However, it is not the node type that hinders home computer mining, but the rapid development of professional mining machines. Compared with ordinary computers, the computing power of ordinary computers is very small. Mining by ordinary computers is like digging your own backyard with a hoe, and then expecting to dig out gold
because of the demand of bitcoin users, bitcoin exchange was born. The exchange provides a place for centralized trading. People put money on the exchange, and the exchange will match and trade together, similar to stocks and securities. Therefore, banning exchanges does not mean banning bitcoin. Bitcoin network cannot be banned. Bitcoin is sent to the exchange's wallet, and all you see is a balance given to you by the exchange. In fact, you no longer have your own bitcoin. Bitcoin network is global. Where there is a network, there will be bitcoin. After the exchange closes, bitcoin will not disappear, but will return to where it should be.

5. The essence of bitcoin is an account book, which keeps all the transaction records of history. Bitcoin client is responsible for interacting with other clients in the form of P2P, so it is also called P2P node. If the client has downloaded all the ledgers, the node is the full node.
6.
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
