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. 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.

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. Compared with them, HNB has three advantages:
1. HNB is an economic model designed to serve the sustainable development of real economy. HNB has great scalability, which is enough to support the continuous growth of HNB community, including the growth of the number of nodes at the bottom of the blockchain, the access of more merchants, the increase of the number of users, etc. it has reached the forefront in the sustainable development and community capacity
2. It has strong interoperability, supports rapid integration and continuous development with existing systems, facilitates docking with other blockchain systems and application systems, and paves the way for future cooperation with major apps
3. It supports millions of users and concurrent transactions, supports the processing of large concurrent transaction peaks, reces transaction confirmation delay, achieves second level consensus efficiency, has strong security at the application and infrastructure level, and protects the privacy of business data and personal data. It has instry-leading technology and security performance.
