One of the foremost concerns regarding the Merge is that of centralization. Another potential concern is the risk of scams, as the general public may not be aware of how the Merge works.
A fundamental flaw in the Merge is that it will likely increase the concentration of power within the network. The more valuable a staker’s position is, the more they will be rewarded for validating blocks. This could lead to a situation where a small number of wealthy individuals or groups control the majority of the stake and have disproportionate influence over the network.
