One class ends up playing the game "Proof-of-work": - The class is collectively building a large lego tower - A student is only allowed to add a brick to the tower after they correctly solve a personalized sudoku - Once they complete the sudoku they can add their brick anywhere. They often add it to the top so that they can claim they're a part of the tallest set of bricks - If they add their brick to the top, other students will pay them (in bricks) to write their own names on it with a sharpie If we were to visit this class, we would likely see every student solving sudokus. The other class plays "Proof-of-stake": - They're also contributing bricks to a large lego tower - If a student wants to add a brick to the tower, they first have to put some of their bricks into the center of the room and give each brick a unqiue number - Each student then rolls their own die and they add up all the numbers to get a single number for the class - They choose the brick labeled by that number - The student whose brick is chosen gets to place it anywhere on the tower, but again, they almost always place it at the top - If they add a brick to the top, other students pay them to write their names on it in sharpie What would we see if we visited this class instead? Well, every student would be rolling dice. ### 1 year later Neither of the classes have had any students move on to the next year. This makes sense because they've only been playing games. The lego towers have become quite tall. The class playing Proof-of-work has now solved all the easy sudokus the teacher prepared for the first year and have moved on to advanced sudokus. They've gotten *really* good at solving them. Some students have complained that most of their dreams are now related to sudokus. It's all they think about. The class playing Proof-of-stake has a lot of notebooks filled with doodles. The teacher hasn't provided the children with much else to do and they've become quite bored. Some students have upgraded their dice to fancy custom color dice. Other students haven't changed their dice at all, as it makes no difference. Interestingly, not one student has become better at rolling dice. ### Another year passes Many students have left both classes. The towers pierce the roof of the building. The first class lost the students that simply couldn't keep up with the increasingly difficult sudokus. They ended up transferring schools and getting a real education. New students tried to transfer in, but without 2 years of constantly solving sudoku under their belt, they couldn't compete with the more experienced sudoku-solvers. The second class *also* lost a bunch of students. Rolling dice turns out to be very boring. However, new students were able to transfer in quite easily. All they had to do was go out and buy some dice and some bricks and they were set to join the game. Admittedly, they didn't have as many bricks as some of their more senior classmates, but they still had a shot every round of the game to get their brick in the tower. ### The fourth year begins The principal steps in and fires both teachers, claiming the games they've been hosting for the past three years are no substitution for education. Such games are for computers.
