# Identity Module
|
|
|
|
- [`identity::Trait`](https://docs.rs/pallet-identity/latest/pallet_identity/trait.Trait.html)
|
|
- [`Call`](https://docs.rs/pallet-identity/latest/pallet_identity/enum.Call.html)
|
|
|
|
## Overview
|
|
|
|
A federated naming system, allowing for multiple registrars to be added from a specified origin.
|
|
Registrars can set a fee to provide identity-verification service. Anyone can put forth a
|
|
proposed identity for a fixed deposit and ask for review by any number of registrars (paying
|
|
each of their fees). Registrar judgements are given as an `enum`, allowing for sophisticated,
|
|
multi-tier opinions.
|
|
|
|
Some judgements are identified as *sticky*, which means they cannot be removed except by
|
|
complete removal of the identity, or by the registrar. Judgements are allowed to represent a
|
|
portion of funds that have been reserved for the registrar.
|
|
|
|
A super-user can remove accounts and in doing so, slash the deposit.
|
|
|
|
All accounts may also have a limited number of sub-accounts which may be specified by the owner;
|
|
by definition, these have equivalent ownership and each has an individual name.
|
|
|
|
The number of registrars should be limited, and the deposit made sufficiently large, to ensure
|
|
no state-bloat attack is viable.
|
|

## Interface
|
|
|
|
### Dispatchable Functions
|
|
|
|
#### For general users
|
|
* `set_identity` - Set the associated identity of an account; a small deposit is reserved if not
|
|
already taken.
|
|
* `clear_identity` - Remove an account's associated identity; the deposit is returned.
|
|
* `request_judgement` - Request a judgement from a registrar, paying a fee.
|
|
* `cancel_request` - Cancel the previous request for a judgement.
|
|
|
|
#### For general users with sub-identities
|
|
* `set_subs` - Set the sub-accounts of an identity.
|
|
* `add_sub` - Add a sub-identity to an identity.
|
|
* `remove_sub` - Remove a sub-identity of an identity.
|
|
* `rename_sub` - Rename a sub-identity of an identity.
|
|
* `quit_sub` - Remove a sub-identity of an identity (called by the sub-identity).
|
|
|
|
#### For registrars
|
|
* `set_fee` - Set the fee required to be paid for a judgement to be given by the registrar.
|
|
* `set_fields` - Set the fields that a registrar cares about in their judgements.
|
|
* `provide_judgement` - Provide a judgement to an identity.
|
|
|
|
#### For super-users
