Banning? Blacklisting? That doesn’t sound very decentralized. What gives?
DESK is not decentralized, nor does it purport to be. It is not competing with bitcoin or ether.
It’s important to remember that not all blockchain assets are fully decentralized or claim to be so. Ether, the native currency of Ethereum, is completely user-controlled, but ERC-20 tokens built on top of the network may or may not be, depending on how the issuer designs it. For example, a number of regulated stablecoins are ERC-20 tokens, and their issuers have the power to freeze funds of suspect addresses to comply with law enforcement requests.
