Ethereum adopts a hybrid consensus mechanism based on Proof of Work (PoW), while Solana uses a more advanced consensus algorithm based on Proof of Stake (PoS).↵↵In Ethereum, due to the presence of the PoW mechanism, nodes need to compete for account rights by solving complex mathematical problems. This mechanism easily leads to wasted computing power and slow  block generation, thus potentially causing duplicate transactions during processing."}]}],"pr":"9fc70a1e3db88fab4d6265ce6d5e8cffc1e25e4e9b1f853ec966361528f45ced"}
