This article mainly introduces "what are the characteristics of the block chain". In the daily operation, I believe that many people have doubts about the characteristics of the block chain. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "what are the characteristics of the block chain?" Next, please follow the editor to study!

1. Openness

This is for the block chain common chain, because the information of the common chain can be read and written by anyone, as long as it is the node of the entire network system and the node with accounting rights. The technical foundation of blockchain is open source. In addition to the private information of all parties involved in the transaction, the data of blockchain is open to everyone, and anyone can query blockchain data and develop related applications through open interfaces. Therefore, the information of the whole system is highly transparent.

2. Independence

Based on the consensus specifications and protocols, the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention. It is precisely because the blockchain adopts consensus-based specifications and protocols that all nodes in the whole system can exchange data freely and safely in an untrusted environment, and the trust in "people" is changed to trust in machines. Any human intervention won't work.

3. Anonymity

Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information transmission can be carried out anonymously. Its anonymity is based on its algorithm that addresses are addressed by address rather than personal identity, which is also a concern for the government. There are two uncontrollable ones in the whole blockchain, one of which is identity uncontrollable anonymity. I don't know who initiated the deal.

4. Decentralization

All the nodes running in the whole blockchain network can be accounted for and have an accounting right, which completely avoids a malpractice of operation centralization. It is not a centralization, it is a disintermediation. Centralization means that, for example, 40% of bitcoin is now in American hands, and it can graft a white glove to stir up the market. This actually has a centralized operating system; the etheric place is heavily held by Jews; and the EOS is concentrated in 21 super nodes. They can only be called weak centralization; due to the use of distributed accounting and storage, there is no centralized hardware or management organization, and the rights and obligations of any node are equal. the data blocks in the system are jointly maintained by the nodes with maintenance functions in the whole system. Any node that stops working will not affect the operation of the system as a whole.

5. Anti-usurpation modification

This feature means that anyone who wants to change the information in the blockchain must attack 51% of the nodes in the network to change the data, which is very difficult. Once the information is verified and added to the blockchain, it will be stored permanently, and unless more than 51% of the nodes in the system can be controlled at the same time, the modification to the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high.

6. Traceability

Its mechanism is to set the latter block to have a hash value of the previous block, just like a hook, which can be hung only if the previous hash value is identified, which is a complete chain. Another good feature of traceability is that it is convenient for data query, because this block is uniquely identified. for example, if you go to the database to query something, there are many algorithms to find it in blocks. in this block chain network, it is more convenient to find the block of this time period by the time node.

At this point, the study of "what are the characteristics of the blockchain" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
