The network composed of all nodes of bitcoin is a kind of networ

1.

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

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

2. Bitcoin is a kind of virtual currency, which 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 in the world

3. 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."

4. Bitcoin blockchain is a bitcoin blockchain? No, the block stores the transaction. In the early stage, you will get a coin if you successfully build a block. In the later stage, you can only get the fees paid by the exchange. A currency is a string of digital signatures. It is a digital signature sent by the last owner to the receiver. Everyone can see who owns the currency from the transaction
does each node have complete blockchain data? You mean a user node? A user node needs to keep the of the block head of the longest workload proof chain, so it knows the data of all the block heads. It can move forward to know all the data on the block chain, but not all of them are saved. A block header is very small, only 80 bytes, which can be saved completely, because the generation of nodes is very slow. Even with the passage of time, the amount is not too large now.

5. Qube exchange answers for you:
1) new transactions broadcast to the whole network
2) each node brings the received transaction information into a block
3) each node tries to find a workload proof with enough difficulty in its own block
4) when a node finds a workload proof, it broadcasts to the whole network
5) if and only if all the transactions contained in the block are valid and have not existed before, other nodes agree with the validity of the block
6) other nodes indicate that they accept the block, and the method of indicating acceptance is to follow the end of the block, create a new block to extend the chain, and regard the random hash value of the accepted block as the random hash value that is faster than the new block
hope to help you.

6. Bitcoin adopts the Internet-based P2P (peer-to-peer) network architecture. P2P means that each computer in the same network is peer-to-peer, each node provides network services together, there is no "special" node. Each network node is connected with each other in a "flat" topology. There is no server, centralized service and hierarchical structure in P2P network. P2P network nodes interact and cooperate: each node provides services to the outside world, but also uses the services provided by other nodes in the network. P2P network is reliable, decentralized and open
the P2P network structure adopted by bitcoin is not just the choice of topology. Bitcoin is designed as a point-to-point digital cash system, and its network architecture is the reflection and cornerstone of this core feature. Decentralized control is the core principle of design, which can only be achieved by maintaining a flat and decentralized P2P consensus network
each node in bitcoin P2P network is peer-to-peer, but according to the different functions provided, the division of labor of each node is not the same. Each bitcoin node is a functional set of routing, blockchain database, mining and wallet services. A bitcoin network node includes four functions: wallet, miner, complete blockchain and network routing node
some nodes keep a complete and up-to-date of the blockchain, which is called "all nodes". The whole node can independently verify all transactions without any external reference. In addition, some nodes only retain part of the blockchain, and they complete transaction verification through a method called "simple payment verification (SPV)". Such a node is called "SPV node", also known as "lightweight node"
mining nodes create new blocks in a competitive way through proof of work (POW) algorithm running on special hardware devices. Some mining nodes are also full nodes, keeping a complete of the blockchain; There are also some nodes involved in the mining of the mine pool, which are lightweight nodes, and they must rely on the whole node maintained by the mine pool server to work
User wallets can also be used as part of the whole node, which is common in desktop bitcoin clients. At present, more and more users' wallets are SPV nodes, especially bitcoin wallets running on resource constrained devices such as smart phones, which is becoming more and more common.

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 money circulation

bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

bitcoin network generates new bitcoin through "mining".

< H2 > extended data

users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold diggers by repeatedly solving riddles to provide the required numbers for bitcoin network. If the user's computer successfully creates a set of numbers

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. The following table lists some websites that download bitcoin wallets and addresses for free

9. If you download apps, you can download them directly from the app market, but some apps that have not been put on the shelves can be downloaded directly from the browser.
