> 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
Other students are paying in bricks? Is that supposed to be transaction fees, mining (that's the sudoku puzzles), or what? And is there any indication that a name on a brick means anything (or can be exchanged for anything)? Is there a limit to the number of names on bricks? Can those names be verified at any instant, anywhere in the world with near 100% confidence?
I know it's a simplification for the purpose of making a point; it's just that the point becomes invalid when the simplification throws out the central characteristics of the thing that's being represented.
