What are the characteristics of blockchain?

Blockchain has the following characteristics:

Decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-checking, transmission and management of information through distributed charging and storage. Decentralization is the most prominent and basic feature of blockchain.

The technical basis of open blockchain is open source code. In addition to the encrypted private information of all parties to the transaction, the blockchain data is open to everyone, and anyone can query the blockchain data through the open interface and develop related applications, so the whole system information is highly transparent.

Independence. Based on the agreed specifications and protocols (similar to various mathematical algorithms such as hash algorithm adopted by Bitcoin), the whole blockchain system does not depend on other third parties, and all nodes can automatically and securely verify and exchange data in the system without any human intervention.
