But PoS can result in Matthew effect and security issues. Since it determines the efficiency by the number of tokens held, the more people who own more tokens, the easier it is to gain more benefits. It will cause the “the stronger becomes stronger, weaker become weaker” phenomenon, meaning smaller users’ would lose their right to speak. Worse, they wouldn’t care about voting governance and ecological construction, contrary to the original intention of decentralisation. Moreover, under the PoS mechanism, if someone wants to counterfeit the tokens, it would be easy to implement by holding a large amount of cryptocurrency. There is no need to invest in any complicated calculations. Compared to PoW, PoS has a lower cost when counterfeiting, and the security of PoS cannot be guaranteed.
