Expand description

Contains a variant per dispatchable extrinsic that this pallet has.

Variants§

§

set_invulnerables

Set the list of invulnerable (fixed) collators. These collators must do some preparation, namely to have registered session keys.

The call will remove any accounts that have not registered keys from the set. That is, it is non-atomic; the caller accepts all AccountIds passed in new individually as acceptable Invulnerables, and is not proposing a set of new Invulnerables.

This call does not maintain mutual exclusivity of Invulnerables and Candidates. It is recommended to use a batch of add_invulnerable and remove_invulnerable instead. A batch_all can also be used to enforce atomicity. If any candidates are included in new, they should be removed with remove_invulnerable_candidate after execution.

Must be called by the UpdateOrigin.

Fields

§new: Vec<T::AccountId>
§

set_desired_candidates

Set the ideal number of non-invulnerable collators. If lowering this number, then the number of running collators could be higher than this figure. Aside from that edge case, there should be no other way to have more candidates than the desired number.

The origin for this call must be the UpdateOrigin.

Fields

§max: u32
§

set_candidacy_bond

Set the candidacy bond amount.

If the candidacy bond is increased by this call, all current candidates which have a deposit lower than the new bond will be kicked from the list and get their deposits back.

The origin for this call must be the UpdateOrigin.

Fields

§bond: <<T as Config>::Currency as Currency<<T as SystemConfig>::AccountId>>::Balance
§

register_as_candidate

Register this account as a collator candidate. The account must (a) already have registered session keys and (b) be able to reserve the CandidacyBond.

This call is not available to Invulnerable collators.

§

leave_intent

Deregister origin as a collator candidate. Note that the collator can only leave on session change. The CandidacyBond will be unreserved immediately.

This call will fail if the total number of candidates would drop below MinEligibleCollators.

§

add_invulnerable

Add a new account who to the list of Invulnerables collators. who must have registered session keys. If who is a candidate, they will be removed.

The origin for this call must be the UpdateOrigin.

Fields

§who: T::AccountId
§

remove_invulnerable

Remove an account who from the list of Invulnerables collators. Invulnerables must be sorted.

The origin for this call must be the UpdateOrigin.

Fields

§who: T::AccountId
§

update_bond

Update the candidacy bond of collator candidate origin to a new amount new_deposit.

Setting a new_deposit that is lower than the current deposit while origin is occupying a top-DesiredCandidates slot is not allowed.

This call will fail if origin is not a collator candidate, the updated bond is lower than the minimum candidacy bond, and/or the amount cannot be reserved.

Fields

§new_deposit: <<T as Config>::Currency as Currency<<T as SystemConfig>::AccountId>>::Balance
§

take_candidate_slot

The caller origin replaces a candidate target in the collator candidate list by reserving deposit. The amount deposit reserved by the caller must be greater than the existing bond of the target it is trying to replace.

This call will fail if the caller is already a collator candidate or invulnerable, the caller does not have registered session keys, the target is not a collator candidate, and/or the deposit amount cannot be reserved.

Fields

§deposit: <<T as Config>::Currency as Currency<<T as SystemConfig>::AccountId>>::Balance
§target: T::AccountId
