Profiles
Profile is essential part of the application. Profile is used to create your onchain identity.
The Profile is used to enrich the AccountID information with user specific metadata such as personal interests, name, reputation, etc. Each User can create a single user profile per AccountID.
By creating a profile, you are broadcasting to the network your self-assigned username and interests.
Anyone is allowed to create a profile.
Keys
Before creating a profile, first you must create your own set of keys.
The public/private key pair is how you authenticate your identity with the application. For more information on how to generate your keys, please refer to our wallet section.
We recommend the use of the polkadot.js chrome extension which automatically loads your keys into the application. An example of how your keys look like within the application is shown below.

Profile Reputation
To ensure that every user acts with integrity, the system keeps track of reputation. Reputation is rewarded each time user contributes to a task, organization. Reputation is taken away when the user negatively contributes to previously established contracts.
The following formula is used to calculate profile reputation when interacting with tasks.
where Reputation(sj) - the assessed reputation of sj as calculated by the service consumer and Cr(x) is the credibility of the service rater x as viewed by the service consumer.
The credibility of a service rater lies in the interval [0,1] with 0 identifying a dishonest rater and 1 an honest one.
