    The `iss` property is a decentralized identifier or `did`. This identifies the user and the user name to the application. The specific `did` is a `btc-addr`.

+## User profiles

+Profile data is stored using Gaia on the user's selected storage provider. An example of a `profile.json` file URL using
+default provided storage:

+
+Follow these steps to create and register a profile for a BNS username (`identifier`):
+
+1. Create a JSON profile object
+2. Split up the profile into tokens, sign the tokens, and put them in a token file
+3. Create a zone file that points to the web location of the profile token file
