1. 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

"Gold and silver are not money naturally, but money is gold and silver naturally." this is a sentence Marx said about money
How to understand? In fact, it is very simple that money is the inevitable proct of the development of human life. In the earliest stage, gold and silver were only used as a kind of metal or a kind of ordinary commodity to exchange things. However, with the development of society, people find that gold and silver are easy to separate, easy to preserve, easy to carry and other advantages, so the suitability of gold and silver as currency is reflected, and naturally evolved into currencyWhat about bitcoin
3. Bitcoin is a kind of digital currency. Bitcoin can only be regarded as an electronic commodity in China. Bitcoin has become a legal currency in Germany. Bitcoin can be regarded as a collection. Collectors regard bitcoin as priceless, while non collectors regard bitcoin as worthless characters.
4. Bitcoin home: it is a bitcoin Chinese portal, which has most of the information users need. Bitcoin home has a wide range of reports, which is more suitable for general investors and Xiao
btc123: it's a bitcoin related navigation website, but it has become a commercial website under the management of Er Bao. It's not as popular as Lao Mo when he was in business. Lao Mo is more idealistic and less commercialized
Xigu and Wanyuan are Shanzhai coin trading platforms, which can be used by those who play Shanzhai coin.

5. 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.
