1. In short, it is an important concept of bitcoin
2. The decentralized nodes in Chongqing jinwowo analysis blockchain technology are as follows:
every central node can generate blocks and write data, so every point is a central node, or the blockchain is decentralized. In order to control the whole system, more than half of the nodes must be controlled in order to control voting, so there is no administrator in this system.

3. A lot of network, or in a group said easy to understand. Teach you to understand with mathematical knowledge (node is a point, block is a line, and blockchain is a surface). Node is the basic unit of information processing in blockchain application technology. After processing information, many nodes will be timestamped, generate data blocks, and connect blocks in time sequence to form blockchain.
4. It contains complete blockchain and network routing nodes, which are only used to synchronize blocks, participate in verification, and maintain connection with peer nodes.
5. Jinwowo analysis: a node is actually a computer (server) connected to the blockchain. Any connected computer can access the blockchain, so there are countless nodes on the blockchain; However, the number of blocks on the blockchain is limited, that is, one block is generated every 10 minutes, and no new blocks will be added after reaching a certain number.
6. A node is a regional server. In the Internet area, all the running data of an enterprise are in a server, then the server is the node
it's like wechat that we use every day, dealing with so many chat messages, transfers and so on. These data are stored and run in Tencent's server. Then the server that processes data can be called "node"
in addition to the world of blockchain, we all know that blockchain is a decentralized distributed database. It does not rely on any centralized server, but is composed of tens of thousands of "small servers". As long as we download a blockchain client, we will become one of the thousands of "small servers"
in this way, if we want to play blockchain, we are equivalent to a node
nodes are also divided into light nodes and full nodes. The whole node is the node that has all the transaction data of the whole network, so the light node only has its own related transaction data node
moreover, the more widely distributed the nodes are, the more decentralized the blockchain network will be, and the more secure and stable the network operation will be. The existence of nodes is the representation of distributed blockchain, and also the charm of blockchain
