* HoldReason: Improve usage `HoldReason` was switched recently to use the `composite_enum` attribute that will merge the enums from all pallets in the runtime to `RuntimeHoldReason`. `pallet-nis` was still requiring that the variant was passed as constant to call `hold`. The proper implementation is to use the `HoldReason` from inside the pallet directly when calling `hold`. This is done by adding a `RuntimeHoldReason` as type to the `Config` trait and requiring that `Currency` is using the same reason. Besides that the pr changes the name `HoldIdentifier` in `pallet_balances::Config` to `RuntimeHoldReason`. * Update frame/nis/src/lib.rs Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Review comment * Fixes --------- Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io>
Identity Module
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.

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.
