1.
The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
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. 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 a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. 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. 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
on December 17, 2017, bitcoin reached an all-time high of $19850. On July 27, 2020, bitcoin broke the $10000 mark again

bitcoin is a kind of network virtual currency, which is similar to Tencent's q-coin. You can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items
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<

bitcoin is a kind of electronic currency proced by open source P2P software. Bitcoin has also been paraphrased as "bitgold". The concept of virtual currency bitcoin was first proposed by Satoshi Nakamoto in 2009. Now bitcoin is also used to refer to bitcoin's open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution, but uses a distributed database throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses the ownership of the bitcoin
features
bitcoin is designed to allow anonymous ownership and use rights. Bitcoin can be stored in personal computers in the form of computer files (wallet) or in third-party hosting services. No matter how it is saved, bitcoin can be sent to anyone on the Internet through its address

8. The reason why blockchain ledger can be decentralized is that all nodes of the network synchronize the ledger with each other and keep consistent. Therefore, blockchain does not need a centralized bookkeeping institution, so what is the node
bitcoin is a kind of point-to-point e-cash system, more directly, node to node. Each transaction is broadcast by the originator to the nodes around it, and then broadcast to the nodes around it after receiving it, and finally spread to the whole network
every bitcoin wallet is a node, and the node with a complete blockchain ledger is called the whole node. In October 2017, there were about 9300 nodes in the bitcoin network, which were responsible for broadcasting and verifying bitcoin transfer transactions. After the transfer transaction occurs, all nodes broadcast to the whole network. After the mining node verifies that the transaction is correct, it will be recorded in the blockchain ledger. The United States, Germany and France have the largest number of bitcoin nodes, with China accounting for about 5% of the world's total nodes Data source: bitcodes. 21. CO) running bitcoin node does not provide any reward, and it does not need the whole node to transfer bitcoin, so the total number of bitcoin nodes only accounts for a small part of the node number.
