Consensus mechanism

The consensus mechanism is how to reach a consensus among all the accounting nodes to determine the validity of a record. This is both a means of identification and a means of preventing tampering. The blockchain proposes four different consensus mechanisms that apply to different application scenarios and strike a balance between efficiency and security.


The consensus mechanism of the blockchain has the characteristics of “minority to majority” and “everyone is equal”. The “minority of majority” does not refer to the number of nodes, but also the computing power, the number of shares, or other computers that can be compared. Feature amount. "Everyone is equal" is when all nodes have the right to give priority to consensus results, directly recognized by other nodes, and finally become the final consensus result.


Taking Bitcoin as an example, the proof of workload is used. Only when the accounting node of the whole network exceeds 51% is controlled, it is possible to forge a record that does not exist. This is basically impossible when there are enough nodes to join the blockchain, thus eliminating the possibility of fraud.
