Raft is like having a group of friends who take turns being the leader to make sure everyone plays fair and knows what's going on.
Imagine you and your friends are playing a game, but no one is in charge. Sometimes people get confused about what move to make next, or someone might think they're the leader when they're not. That’s where Raft comes in, it helps pick a leader who can keep things organized.
How Raft Works
In Raft, there are different roles:
- The leader is like the person who calls out the moves.
- The followers listen and follow along.
- If the leader gets distracted or leaves, someone else can step up to be the new leader, just like when your friend goes to the restroom, and another kid takes over calling the game.
Everyone in the group agrees on what’s happening at the same time. That way, no one gets left behind or confused. It's a simple but clever system that keeps things running smoothly, just like how you and your friends can keep playing without any fights or confusion.
Examples
- A class of students taking turns leading a discussion so everyone stays on the same page.
- A team of chefs working together to cook a big meal without getting confused.
