In a blockchain system, the consensus mechanism is the core part that ensures the security and stability of the network. Currently, the most commonly used consensus mechanisms are Proof of Work (PoW) and Proof of Stake (PoS).\n\nUnder the Proof of Work (PoW) mechanism, miners in the blockchain network need to obtain a difficult-to-generate but easy-to-verify proof through calculation. This process consumes a large amount of computing resources. To compete for block rewards, miners continuously increase their computing power, leading  to a rapid rise in energy consumption. In addition, due to the inherent characteristics of PoW, a large amount of electricity is wasted in the process of mining, which is not environmentally friendly."}]}],"pr":"6269a5b9d59e30f76c17a9766f893670bb18ded9f604a4cdfc6ffdbf1a9fbaec"}
