Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies.

Second, the characteristics

1, 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. ?

2. openness. ?

The technical basis of blockchain is open source. 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.

3. independence. ?

Based on the agreed specifications and protocols, the whole blockchain system does not depend on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention. ?

4. Safety. ?

As long as all data nodes of 5 1% cannot be controlled, network data cannot be manipulated and modified at will, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes. ?

5. anonymity. ?

Unless there is a legal requirement, technically, the identity information of each block node does not need to be disclosed or verified, and the information transmission can be anonymous? . ?
