pezpallet-identity
Identity Pezpallet
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.
Usernames
The pezpallet provides functionality for username authorities to issue usernames, which are independent of the identity information functionality; an account can set:
- an identity without setting a username
- a username without setting an identity
- an identity and a username
The username functionality implemented in this pezpallet is meant to be a user friendly lookup of accounts. There are mappings in both directions, "account -> username" and "username -> account".
To grant a username, a username authority can either:
- be given an allocation by governance of a specific amount of usernames to issue for free, without any deposit associated with storage costs;
- put up a deposit for each username it issues (usually a subsidized, reduced deposit, relative to other deposits in the system).
Users can have multiple usernames that map to the same AccountId, however one AccountId can only
map to a single username, known as the primary. This primary username will be the result of a
lookup in the UsernameOf map for any given account.
