Why is POS choosen instead of Dpos?
There are pro/cons with either option. afaik, when this came up in discussions with the team, x42 will move to DPoS if there is a strong community push for it.
PoS is not secured, centralised and unfair to smaller players.
Not entirely true, take a look at DPoS coins, and you can see the problems they've been encountering with large holders. They both have their positives and negatives. With PoS, Every transaction must be double-validated by a random staker and master node, and then confirmed 50 consecutive times by random contributors.
