3. Proof of Stake disadvantages:
Validators are frequently selected at random from all participants in proof-
of- stake (POS) cryptocurrencies. Users with a greater stake have a better
chance of being selected. This may cause problems, such as the rich
getting richer and dominating the consensus process, which may harm the
network. Proof of Stake protocols may be very complex due to the
numerous factors that game theory has to take into consideration when
creating them, this counts as one of the Proof of Stake disadvantages.
Users compete using a Proof of Stake algorithm to find out who’s the most
secure, but very little energy is consumed in this process, only enough to
keep the CPU running and keep connected to the Internet at all times.
Using a proof of stake mechanism, users receive the same payout,
regardless of how much they have deposited. There is a linear relationship
between profitability and the amount deposited. There is no investmentin
it, another Proof of Stake disadvantages.Crypto money is received by a
staker, and at the same time, his expenses arrive. The result is a positive
cash flow in the short-term.
