** If the issuer wants the earner to be able to store the badge outside the OBI, they can optionally push it to the [https://github.com/mozilla/openbadges/wiki/Badge-Baking Mozilla Baking Service] where the assertion URL representing JSON blobs is embedded into PNG files. Otherwise badge baking is handled through the Issuer API.
* Displayers pull unpacked badges (JSON) out of the Backpack based on earner action and privacy settings.
* Public badges are discoverable based on earner’s email address.
* Earners can share their badges through their Backpack and grant permission for a particular site to display that collection of badges.
* Displayers authenticate badges with the issuer using a verification check.
