Crown Platform Unique Address Prefix
Motivation
Crown addresses have prefixes 1 and 3 as in Bitcoin now. In order to make Crown addresses unique, new prefixes should be added instead. For example, Trezor wallet cannot distinguish the difference between Crown and Bitcoin now, so it's necessary to build a unique namespace for Crown addresses.
