For users who are converting their Listia credits into XNK, the Listia user account just needs to be a verified account as defined on listia.com right now. This typically includes a verified phone number and/or address. SO it shouldn't be too complicated at all.
For participants in the upcoming pre-sale and crowd sale, their will be a more through KYC process for our whitelist coming soon.
There will be a slight transition period as older credit listings disappear, and all new listings are listed in XNK. However, both currencies will be able to be used on any type of listing
It will last as long as there are still old credit listings that are live.. but basically after a week, almost everything will be in XNK.
