What are the characteristics of blockchain?

Blockchain technology is very popular now, but many people don't know much about blockchain. What are the characteristics of that blockchain?

Mainly includes the following six characteristics:

scatter

Because of distributed computing and storage, there is no centralized hardware and management mechanism, and the rights and obligations of any node are equal. Data blocks in the system are maintained by nodes with maintenance function. If any node stops working, it will not affect the operation of the whole system.

trust

All nodes in the system can conduct untrusted transactions, because the operation of the database and the whole system is open and transparent, and nodes cannot cheat each other within the rules and time range of the system.

make public

The system is open, except the private information encryption of the transaction party, the data of the blockchain is open to everyone, and anyone can query the data of the blockchain through the open interface and develop related applications, so the information of the whole system is highly transparent.

exercise autonomy

The blockchain adopts consensus specification and negotiation, so that all nodes of the whole system can exchange data freely and safely in a trusted environment, and the trust in people becomes the trust in machines, and no one's intervention will work.

Information cannot be tampered with.

After the information is verified and added to the blockchain, it will be permanently saved. Unless the number of nodes in the system exceeds 5 1%, the modification of the database by a single node is invalid, so the data stability and reliability of the blockchain are extremely high.

not reveal one's name

Because the replacement of nodes follows a fixed algorithm, their data interaction does not need trust (the program rules in the blockchain judge whether the activity is effective or not), and the transaction object does not need to trust the object through public identity, which is very helpful for the accumulation of credit.
