Crate pallet_identity

Expand description

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.
