It can maintain decentralization better than any other coin because it has zpos zerocoin stakers as well as masternode governance. The zerocoin stakers are UNTRACEABLE which means that the network can basically never be shut down by tracking the stakers. The masternode system has many many masternodes like Dash and these serve to vote on new code in proposals. The coin can not change or do anything without these 2 governance systems working in coordination.
