A mini-code is a 6 letter temporary code that your device can associated with a dedicated invitation twincode. The mini-code is valid for a limited duration, usually 24 hours (but we may reduce this duration in the future). It is intended to be used only to establish a relation.

The mini-code is created on your demand when you want to share your invitation link to someone either by hand writing or by speaking to the person. When it is created, a dedicated twincode is created by copying the information of your profiles and the server associates that twincode to a unique mini-code that it returns to you. The server also records the public key that was used to sign the twincode attributes.

When the peer enters the mini-code, the information is retrieved from the server and the contact relation is established if such mini-code was still valid.
