impl<T: Config> Pallet<T>
sourcepub fn slashable_balance_of(stash: &T::AccountId) -> BalanceOf<T>
pub fn slashable_balance_of(stash: &T::AccountId) -> BalanceOf<T>
The total balance that can be slashed from a stash account as of right now.
sourcepub fn slashable_balance_of_vote_weight(
stash: &T::AccountId,
issuance: BalanceOf<T>
) -> VoteWeight
pub fn slashable_balance_of_vote_weight( stash: &T::AccountId, issuance: BalanceOf<T> ) -> VoteWeight
Internal impl of Self::slashable_balance_of
that returns VoteWeight
.
sourcepub fn weight_of_fn() -> Box<dyn Fn(&T::AccountId) -> VoteWeight>
pub fn weight_of_fn() -> Box<dyn Fn(&T::AccountId) -> VoteWeight>
Returns a closure around slashable_balance_of_vote_weight
that can be passed around.
This prevents call sites from repeatedly requesting total_issuance
from backend. But it is
important to be only used while the total issuance is not changing.
sourcepub fn weight_of(who: &T::AccountId) -> VoteWeight
pub fn weight_of(who: &T::AccountId) -> VoteWeight
Same as weight_of_fn
, but made for one time use.
sourcepub fn trigger_new_era(
start_session_index: SessionIndex,
exposures: BoundedVec<(T::AccountId, Exposure<T::AccountId, BalanceOf<T>>), MaxWinnersOf<T>>
) -> BoundedVec<T::AccountId, MaxWinnersOf<T>>
pub fn trigger_new_era( start_session_index: SessionIndex, exposures: BoundedVec<(T::AccountId, Exposure<T::AccountId, BalanceOf<T>>), MaxWinnersOf<T>> ) -> BoundedVec<T::AccountId, MaxWinnersOf<T>>
Plan a new era.
- Bump the current era storage (which holds the latest planned era).
- Store start session index for the new planned era.
- Clean old era information.
- Store staking information for the new planned era
Returns the new validator set.
sourcepub fn store_stakers_info(
exposures: BoundedVec<(T::AccountId, Exposure<T::AccountId, BalanceOf<T>>), MaxWinnersOf<T>>,
new_planned_era: EraIndex
) -> BoundedVec<T::AccountId, MaxWinnersOf<T>>
pub fn store_stakers_info( exposures: BoundedVec<(T::AccountId, Exposure<T::AccountId, BalanceOf<T>>), MaxWinnersOf<T>>, new_planned_era: EraIndex ) -> BoundedVec<T::AccountId, MaxWinnersOf<T>>
Process the output of the election.
Store staking information for the new planned era
sourcepub fn reward_by_ids(
validators_points: impl IntoIterator<Item = (T::AccountId, u32)>
)
pub fn reward_by_ids( validators_points: impl IntoIterator<Item = (T::AccountId, u32)> )
Add reward points to validators using their stash account ID.
Validators are keyed by stash account ID and must be in the current elected set.
For each element in the iterator the given number of points in u32 is added to the validator, thus duplicates are handled.
At the end of the era each the total payout will be distributed among validator relatively to their points.
COMPLEXITY: Complexity is number_of_validator_to_reward x current_elected_len
.
sourcepub fn get_npos_voters(maybe_max_len: Option<usize>) -> Vec<VoterOf<Self>>
pub fn get_npos_voters(maybe_max_len: Option<usize>) -> Vec<VoterOf<Self>>
Get all of the voters that are eligible for the npos election.
maybe_max_len
can imposes a cap on the number of voters returned;
Sets MinimumActiveStake
to the minimum active nominator stake in the returned set of
nominators.
This function is self-weighing as DispatchClass::Mandatory
.
sourcepub fn get_npos_targets(maybe_max_len: Option<usize>) -> Vec<T::AccountId>
pub fn get_npos_targets(maybe_max_len: Option<usize>) -> Vec<T::AccountId>

.
sourcepub fn do_add_nominator(who: &T::AccountId, nominations: Nominations<T>)
pub fn do_add_nominator(who: &T::AccountId, nominations: Nominations<T>)
This function will add a nominator to the Nominators
storage map,
and VoterList
.
If the nominator already exists, their nominations will be updated.
NOTE: you must ALWAYS use this function to add nominator or update their targets. Any access
to Nominators
or VoterList
outside of this function is almost certainly
wrong.
sourcepub fn do_remove_nominator(who: &T::AccountId) -> bool
pub fn do_remove_nominator(who: &T::AccountId) -> bool
This function will remove a nominator from the Nominators
storage map,
and VoterList
.
Returns true if who
was removed from Nominators
, otherwise false.
NOTE: you must ALWAYS use this function to remove a nominator from the system. Any access to
Nominators
or VoterList
outside of this function is almost certainly
wrong.
sourcepub fn do_add_validator(who: &T::AccountId, prefs: ValidatorPrefs)
pub fn do_add_validator(who: &T::AccountId, prefs: ValidatorPrefs)
This function will add a validator to the Validators
storage map.
If the validator already exists, their preferences will be updated.
NOTE: you must ALWAYS use this function to add a validator to the system. Any access to
Validators
or VoterList
outside of this function is almost certainly
wrong.
sourcepub fn do_remove_validator(who: &T::AccountId) -> bool
pub fn do_remove_validator(who: &T::AccountId) -> bool
This function will remove a validator from the Validators
storage map.
Returns true if who
was removed from Validators
, otherwise false.
NOTE: you must ALWAYS use this function to remove a validator from the system. Any access to
Validators
or VoterList
outside of this function is almost certainly
wrong.

sourcepub fn bond(
origin: OriginFor<T>,
controller: <<T as Config>::Lookup as StaticLookup>::Source,
value: BalanceOf<T>,
payee: RewardDestination<T::AccountId>
) -> DispatchResult
pub fn bond( origin: OriginFor<T>, controller: <<T as Config>::Lookup as StaticLookup>::Source, value: BalanceOf<T>, payee: RewardDestination<T::AccountId> ) -> DispatchResult
Take the origin account as a stash and lock up value
of its balance. controller
will
be the account that controls it.
value
must be more than the minimum_balance
specified by T::Currency
.
The dispatch origin for this call must be Signed by the stash account.
Emits Bonded
.
- Independent of the arguments. Moderate complexity.
- O(1).
- Three extra DB entries.
NOTE: Two of the storage writes (Self::bonded
, Self::payee
) are never cleaned
unless the origin
falls below existential deposit and gets removed as dust.
sourcepub fn bond_extra(
origin: OriginFor<T>,
max_additional: BalanceOf<T>
) -> DispatchResult
pub fn bond_extra( origin: OriginFor<T>, max_additional: BalanceOf<T> ) -> DispatchResult
Add some extra amount that have appeared in the stash free_balance
into the balance up
for staking.
The dispatch origin for this call must be Signed by the stash, not the controller.
Use this if there are additional funds in your stash account that you wish to bond.
Unlike bond
or unbond
this function does not impose
any limitation on the amount that can be added.
Emits Bonded
.
- Independent of the arguments. Insignificant complexity.
- O(1).
sourcepub fn unbond(
origin: OriginFor<T>,
value: BalanceOf<T>
) -> DispatchResultWithPostInfo
pub fn unbond( origin: OriginFor<T>, value: BalanceOf<T> ) -> DispatchResultWithPostInfo
Schedule a portion of the stash to be unlocked ready for transfer out after the bond period ends. If this leaves an amount actively bonded less than T::Currency::minimum_balance(), then it is increased to the full amount.
The dispatch origin for this call must be Signed by the controller, not the stash.
Once the unlock period is done, you can call withdraw_unbonded
to actually move
the funds out of management ready for transfer.
No more than a limited number of unlocking chunks (see MaxUnlockingChunks
)
can co-exists at the same time. If there are no unlocking chunks slots available
Call::withdraw_unbonded
is called to remove some of the chunks (if possible).
If a user encounters the InsufficientBond
error when calling this extrinsic,
they should call chill
first in order to free up their bonded funds.
Emits Unbonded
.
See also Call::withdraw_unbonded
.
sourcepub fn withdraw_unbonded(
origin: OriginFor<T>,
num_slashing_spans: u32
) -> DispatchResultWithPostInfo
pub fn withdraw_unbonded( origin: OriginFor<T>, num_slashing_spans: u32 ) -> DispatchResultWithPostInfo
Remove any unlocked chunks from the unlocking
queue from our management.
This essentially frees up that balance to be used by the stash account to do whatever it wants.
The dispatch origin for this call must be Signed by the controller.
Emits Withdrawn
.
See also Call::unbond
.
Complexity O(S) where S is the number of slashing spans to remove NOTE: Weight annotation is the kill scenario, we refund otherwise.
sourcepub fn validate(origin: OriginFor<T>, prefs: ValidatorPrefs) -> DispatchResult
pub fn validate(origin: OriginFor<T>, prefs: ValidatorPrefs) -> DispatchResult

for the origin controller.
Effects will be felt at the beginning of the next era.
The dispatch origin for this call must be Signed by the controller, not the stash.

) -> DispatchResultWithPostInfo
pub fn payout_stakers( origin: OriginFor<T>, validator_stash: T::AccountId, era: EraIndex ) -> DispatchResultWithPostInfo
Pay out all the stakers behind a single validator for a single era.
validator_stash

N is the Number of payouts for the validator (including the validator) Weight:
-
Reward Destination Staked: O(N)
-
Reward Destination Controller (Creating): O(N)
NOTE: weights are assuming that payouts are made to alive stash account (Staked). Paying even a dead controller is cheaper weight-wise. We don’t do any refunds here.
sourcepub fn rebond(

num_slashing_spans: u32
) -> DispatchResultWithPostInfo
pub fn reap_stash( origin: OriginFor<T>, stash: T::AccountId, num_slashing_spans: u32 ) -> DispatchResultWithPostInfo
Remove all data structures concerning a staker/stash once it is at a state where it can
be considered dust
in the staking system. The requirements are:
- the
total_balance
of the stash is below existential deposit. - or, the
ledger.total
of the stash is below existential deposit.
The former can happen in cases like a slash; the latter when a fully unbonded account
is still receiving staking rewards in RewardDestination::Staked
.
It can be called by anyone, as long as stash
meets the above requirements.
Refunds the transaction fees upon successful execution.
sourcepub fn kick(
origin: OriginFor<T>,

) -> DispatchResult
pub fn kick( origin: OriginFor<T>, who: Vec<<<T as Config>::Lookup as StaticLookup>::Source> ) -> DispatchResult
Remove the given nominations from the calling validator.
Effects will be felt at the beginning of the next era.
The dispatch origin for this call must be Signed by the controller, not the stash.
who
: A list of nominator stash accounts who are nominating this validator which should no longer be nominating this validator.
Note: Making this call only makes sense if you first set the validator preferences to block any further nominations.
sourcepub fn set_staking_configs(

Update the various staking configurations .
min_nominator_bond
: The minimum active bond needed to be a nominator.min_validator_bond
: The minimum active bond needed to be a validator.max_nominator_count
: The max number of users who can be a nominator at once. When set toNone
, no limit is enforced.max_validator_count
: The max number of users who can be a validator at once. When set toNone
, no limit is enforced.chill_threshold
: The ratio ofmax_nominator_count
ormax_validator_count
which should be filled in order for thechill_other
transaction to work.min_commission
: The minimum amount of commission that each validators must maintain. This is checked only upon callingvalidate
. Existing validators are not affected.
RuntimeOrigin must be Root to call this function.
NOTE: Existing nominators and validators will not be affected by this update.
to kick people under the new limits, chill_other
should be called.
sourcepub fn chill_other(
origin: OriginFor<T>,
controller: T::AccountId
) -> DispatchResult
pub fn chill_other( origin: OriginFor<T>, controller: T::AccountId ) -> DispatchResult
Declare a controller
to stop participating as either a validator or nominator.
Effects will be felt at the beginning of the next era.
The dispatch origin for this call must be Signed, but can be called by anyone.
If the caller is the same as the controller being targeted, then no further checks are
enforced, and this function behaves just like chill
.
If the caller is different than the controller being targeted, the following conditions must be met:
controller
must belong to a nominator who has become non-decodable,
Or:
- A
ChillThreshold
must be set and checked which defines how close to the max nominators or validators we must reach before users can start chilling one-another. - A
MaxNominatorCount
andMaxValidatorCount
must be set which is used to determine how close we are to the threshold. - A
MinNominatorBond
andMinValidatorBond
must be set and checked, which determines if this is a person that should be chilled because they have not met the threshold bond required.
This can be helpful if bond requirements are updated, and we need to remove old users who do not satisfy these requirements.
sourcepub fn force_apply_min_commission(
origin: OriginFor<T>,
validator_stash: T::AccountId
) -> DispatchResult
pub fn force_apply_min_commission( origin: OriginFor<T>, validator_stash: T::AccountId ) -> DispatchResult
Force a validator to have at least the minimum commission. This will not affect a validator who already has a commission greater than or equal to the minimum. Any account can call this.
sourcepub fn set_min_commission(origin: OriginFor<T>, new: Perbill) -> DispatchResult
pub fn set_min_commission(origin: OriginFor<T>, new: Perbill) -> DispatchResult
Sets the minimum amount of commission that each validators must maintain.
This call has lower privilege requirements than set_staking_config
and can be called
by the T::AdminOrigin
. Root can always call this.

pub fn nominators<KArg>(k: KArg) -> Option<Nominations<T>>where KArg: EncodeLike<T::AccountId>,
The map from nominator stash key to their nomination preferences, namely the validators that they wish to support.
Note that the keys of this storage map might become non-decodable in case the
Config::MaxNominations
configuration is decreased. In this rare case, these nominators
are still existent in storage, their key is correct and retrievable (i.e. contains_key
indicates that they exist), but their value cannot be decoded. Therefore, the non-decodable
nominators will effectively not-exist, until they re-submit their preferences such that it
is within the bounds of the newly set Config::MaxNominations
.
This implies that ::iter_keys().count()
and ::iter().count()
might return different
values for this map. Moreover, the main ::count()
is aligned with the former, namely the
number of keys that exist.
Lastly, if any of the nominators become non-decodable, they can be chilled immediately via
Call::chill_other
dispatchable by anyone.

is a secure hash.

sourcepub fn offending_validators() -> Vec<(u32, bool)>
pub fn offending_validators() -> Vec<(u32, bool)>
Indices of validators that have offended in the active era and whether they are currently disabled.
This value should be a superset of disabled validators since not all offences lead to the
validator being disabled (if there was no slash). This is needed to track the percentage of
validators that have offended in the current era, ensuring a new era is forced if
OffendingValidatorsThreshold
is reached. The vec is always kept sorted so that we can find
whether a given validator has previously offended using binary search. It gets cleared when
the era ends.
