Nodes with more tokens and a longer holding period have a higher chance of obtaining accounting rights. Compared to PoW, PoS has lower energy consumption and is more friendly to the environment. However, it is less decentralized and may lead to centralization due to the concentration of tokens in a few hands."}]}],"pr":"4c03657e9a590096bf34889c1ce35248c4d677cc8dd9a47695421c232408e228"}
