What is PoW? Why Can Mining Make Money? Where Does the Money Come From?
Consensus mechanism is a rule that every nodes in the blockchain must comply to. Generally speaking, everyone needs to agree with the framework they are in. Its value comes from the recognition of each nodes. For example, the money we use in the real world is not only because the government has given “this piece of paper” value, but more importantly, each of us agrees that “this piece of paper” is valuable.
