What is the consensus mechanism of blockchain? Brother Yu will show you how

The consensus mechanism of blockchain is like the rules for a group of people to make decisions together.

Imagine a village where people have to decide a big thing, such as whether to build a road. If there is no good way to make a decision, then everyone may quarrel.

It is the same in the blockchain world. Many nodes (like people in the village) have to agree on something. The consensus mechanism is a method used to ensure that everyone agrees on the same thing.

For example, there is a consensus mechanism called Proof of Work, which is like everyone competing in mining. Whoever mines the mine first has the right to speak, and everyone listens to him. This process is very laborious, just like you work hard to complete a difficult task.

There is also a Proof of Stake, which is like the rich people in the village have more weight in their words. Whoever has more coins (like money) is more likely to be selected to make decisions.

In short, the consensus mechanism is to enable the various nodes on the blockchain to work together harmoniously, jointly confirm transactions and record information, and ensure the stable and secure operation of the entire blockchain system.
