Blockchain grabs nodes

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. It contains complete blockchain and network routing nodes, which are only used to synchronize blocks, participate in verification, and maintain connection with peer nodes.
3. 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.
4. It depends on whether you invest. If you don't invest, you can make money by checking in every day. If you invest in the miner, the income will be higher.
5. View the usage of mod, and add it in mod option (main interface).
6. Beck chain uses two ways to effectively fight against centralization and prevent joint evils among nodes:
first, expand the scope of integrity candidate nodes to 5% of all nodes, and randomly select consensus and accounting nodes from the candidate pool according to the time task. The larger the scope of nodes involved in the consensus, the less likely it is to commit joint crimes< Second, select nodes based on bit-r reputation value. Bit-r reputation value is the behavior portrait and historical transaction record of each user and node, which cannot be merged and transferred like token, so the feasibility of joint evil between nodes is small.
