Different consensus algorithms have different requirements for computational resources. For example, the Proof of Work (PoW) consensus algorithm requires nodes to solve a complex mathematical problem, thereby limiting the use of computational resources. However, the PoW algorithm has a significant energy consumption problem because a large amount of computation is needed to solve the mathematical puzzles. To address this issue, some blockchain networks have adopted the Proof of Stake (PoS) consensus algorithm."}]}],"pr":"0576efedbbe39186f1f01f86276a5ba06ccaddfcff5ec65210b6fe55fe99d515"}
