Bitcoin uses this consensus  mechanism. Miners compete to solve the puzzle, and the first to solve it adds a new block to the blockchain and receives corresponding rewards. This mechanism prevents fraud such as double spending."}]}],"pr":"f18b461bec8756fbf26034a1cde7c2eeeb1c32a7710a7a7b0bdb75967edb279b"}
