1. Nodes are the places where the blocks are connected, and the blocks need to be chained to be useful
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
1. In a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
2. Broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code.

2. In short, it is an important concept of bitcoin
3. What are the categories of wallets
previously, we learned the various forms of wallets, and we also learned that wallets are actually "management tools for private key, address and blockchain data". According to the maintenance mode of blockchain data and the degree of decentralization of wallets, we can divide wallets into full node wallets, light wallets and centralized wallets
the representative of all nodes is bitcoin core wallet, which needs to synchronize all blockchain data and takes up a lot of memory, but it can be completely decentralized. Light wallet relies on other all nodes in bitcoin network, only synchronizes data related to itself, which can basically achieve decentralization
centralized wallet does not rely on bitcoin network. All data are obtained from its own centralized server, but the transaction efficiency is very high, and it can be received in real time. The account you register in the transaction platform is the centralized wallet.

4. 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.

5. 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.
6. It contains complete blockchain and network routing nodes, which are only used to synchronize blocks, participate in verification, and maintain connection with peer nodes.
