The consensus mechanism can be defined as a series of steps taken by intersections in a blockchain so that all agree on a proposed state or value. Consensus mechanism is popularized with the emergence of blockchain and Bitcoin.
The Leader election-based consensus mechanism can be defined as an arrangement in which nodes are required to face off with each other in leader-election lottery, and the node that will win will get to propose the final value.
