Storage

The following sections contain Storage methods are part of the default Kusama runtime. On the api, these are exposed via api.query.<module>.<method>.

(NOTE: These were generated from a static/snapshot view of a recent default Kusama runtime. Some items may not be available in older nodes, or in any customized implementations.)


assetRate

conversionRateToNative(PolkadotRuntimeCommonImplsVersionedLocatableAsset): Option<u128>

  • interface: api.query.assetRate.conversionRateToNative

    E.g. native_amount = asset_amount * ConversionRateToNative::<T>::get(asset_kind)


auctions

auctionCounter(): u32

  • interface: api.query.auctions.auctionCounter
  • summary: Number of auctions started so far.

auctionInfo(): Option<(u32,u32)>

  • interface: api.query.auctions.auctionInfo

  • summary: Information relating to the current auction, if there is one.

    The first item in the tuple is the lease period index that the first of the four contiguous lease periods on auction is for. The second is the block number when the auction will "begin to end", i.e. the first block of the Ending Period of the auction.

reservedAmounts((AccountId32,u32)): Option<u128>

authorVrfRandomness(): Option<[u8;32]>

  • interface: api.query.babe.authorVrfRandomness

  • summary: This field should always be populated during block processing unless secondary plain slots are enabled (which don't contain a VRF output).

    It is set in on_finalize, before it will contain the value from the last block.

currentSlot(): u64

  • interface: api.query.babe.currentSlot
  • summary: Current slot number.

epochConfig(): Option<SpConsensusBabeBabeEpochConfiguration>

  • interface: api.query.babe.epochConfig
  • summary: The configuration for the current epoch. Should never be None as it is initialized in genesis.

epochIndex(): u64

  • interface: api.query.babe.epochIndex
  • summary: Current epoch index.

epochStart(): (u32,u32)

  • interface: api.query.babe.epochStart
  • summary: The block numbers when the last and current epoch have started, respectively N-1 and N. NOTE: We track this is in order to annotate the block number when a given pool of entropy was fixed (i.e. it was known to chain observers). Since epochs are defined in slots, which may be skipped, the block numbers may not line up with the slot numbers.

genesisSlot(): u64

  • interface: api.query.babe.genesisSlot
  • summary: The slot at which the first epoch actually started. This is 0 until the first block of the chain.

initialized(): Option<Option<SpConsensusBabeDigestsPreDigest>>

lateness(): u32

  • interface: api.query.babe.lateness

    Security

    This MUST NOT be used for gambling, as it can be influenced by a malicious validator in the short term. It MAY be used in many cryptographic protocols, however, so long as one remembers that this (like everything else on-chain) it is public. For example, it can be used where a number is needed that cannot have been chosen by an adversary, for purposes such as public-coin zero-knowledge proofs.

segmentIndex(): u32

  • interface: api.query.babe.segmentIndex

  • summary: Randomness under construction.

    We make a trade-off between storage accesses and list length. We store the under-construction randomness in segments of up to UNDER_CONSTRUCTION_SEGMENT_LENGTH.

    Once a segment reaches this length, we begin the next one. We reset all segments and return to 0 at the beginning of every epoch.

skippedEpochs(): Vec<(u64,u32)>

  • interface: api.query.babe.skippedEpochs

  • summary: A list of the last 100 skipped epochs and the corresponding session index when the epoch was skipped.

    This is only used for validating equivocation proofs. An equivocation proof must contains a key-ownership proof for a given session, therefore we need a way to tie together sessions and epoch indices, i.e. we need to validate that a validator was the owner of a given key on a given session, and what the active epoch index was during that session.

underConstruction(u32): Vec<[u8;32]>

  • interface: api.query.babe.underConstruction
  • summary: TWOX-NOTE: SegmentIndex is an increasing integer, so this is okay.

balances

account(AccountId32): PalletBalancesAccountData

  • interface: api.query.balances.account

  • summary: The Balances pallet example of storing the balance of an account.

    Example

    nocompile impl pallet_balances::Config for Runtime { type AccountStore = StorageMapShim<Self::Account<Runtime>, frame_system::Provider<Runtime>, AccountId, Self::AccountData<Balance>> }

    You can also store the balance of an account in the System pallet.

    Example

    nocompile impl pallet_balances::Config for Runtime { type AccountStore = System }

    But this comes with tradeoffs, storing account balances in the system pallet stores frame_system data alongside the account data contrary to storing account balances in the Balances pallet, which uses a StorageMap to store balances data only. NOTE: This is only used in the case that this pallet is used to store balances.

freezes(AccountId32): Vec<{"id":"StagingKusamaRuntimeRuntimeFreezeReason","amount":"u128"}>

  • interface: api.query.balances.freezes
  • summary: Freeze locks on account balances.

  • summary: Authorities set scheduled to be used with the next session

setIdSession(u64): Option<u32>

  • interface: api.query.beefy.setIdSession

  • summary: A mapping from BEEFY set ID to the index of the most recent session for which its members were responsible.

    This is only used for validating equivocation proofs. An equivocation proof must contains a key-ownership proof for a given session, therefore we need a way to tie together sessions and BEEFY set ids, i.e. we need to validate that a validator was the owner of a given key on a given session, and what the active set ID was during that session.

    TWOX-NOTE: ValidatorSetId is not under user control.

  • summary: Buffered session changes along with the block number at which they should be applied.

    Typically this will be empty or one element long. Apart from that this item never hits the storage.

    However this is a Vec regardless to handle various edge cases that may occur at runtime upgrade boundaries or if governance intervenes.

hasInitialized(): Option<Null>

  • interface: api.query.initializer.hasInitialized

  • summary: Whether the parachains modules have been initialized within this block.

    Semantically a bool, but this guarantees it should never hit the trie, as this is cleared in on_finalize and Frame optimizes None values to be empty values.

    As a bool, set(false) and remove() both lead to the next get() being false, but one of them writes to the trie and one does not. This confusion makes Option<()> more suitable for the semantics of this variable.


messageQueue

bookStateFor(PolkadotRuntimeParachainsInclusionAggregateMessageOrigin): PalletMessageQueueBookState

  • interface: api.query.messageQueue.bookStateFor
  • summary: The index of the first and last (non-empty) pages.

  • interface: api.query.nis.queueTotals

  • summary: The totals of items and balances within each queue. Saves a lot of storage reads in the case of sparsely packed queues.

    The vector is indexed by duration in Periods, offset by one, so information on the queue whose duration is one Period would be storage 0.

  • interface: api.query.nis.receipts
  • summary: The currently outstanding receipts, indexed according to the order of creation.

    Example

    nocompile impl pallet_balances::Config for Runtime { type AccountStore = StorageMapShim<Self::Account<Runtime>, frame_system::Provider<Runtime>, AccountId, Self::AccountData<Balance>> }

    You can also store the balance of an account in the System pallet.

    Example

    nocompile impl pallet_balances::Config for Runtime { type AccountStore = System }

    But this comes with tradeoffs, storing account balances in the system pallet stores frame_system data alongside the account data contrary to storing account balances in the Balances pallet, which uses a StorageMap to store balances data only. NOTE: This is only used in the case that this pallet is used to store balances.

freezes(AccountId32): Vec<FrameSupportTokensMiscIdAmount>

  • interface: api.query.nisCounterpartBalances.freezes

minCreateBond(): u128

  • interface: api.query.nominationPools.minCreateBond

  • summary: Minimum bond required to create a pool.

    This is the amount that the depositor must put as their initial stake in the pool, as an indication of "skin in the game".

reversePoolIdLookup(AccountId32): Option<u32>

  • interface: api.query.nominationPools.reversePoolIdLookup

  • summary: A reverse lookup from the pool's account id to its id.

    This is only used for slashing and on automatic withdraw update. In all other instances, the pool id is used, and the accounts are deterministically derived from it.

rewardPools(u32): Option<PalletNominationPoolsRewardPool>

  • interface: api.query.nominationPools.rewardPools
  • summary: Reward pools. This is where there rewards for each pool accumulate. When a members payout is claimed, the balance comes out of the reward pool. Keyed by the bonded pools account.

subPoolsStorage(u32): Option<PalletNominationPoolsSubPools>

  • interface: api.query.nominationPools.subPoolsStorage
  • summary: Groups of unbonding pools. Each group of unbonding pools belongs to a bonded pool, hence the name sub-pools. Keyed by the bonded pools account.

totalValueLocked(): u128

  • interface: api.query.nominationPools.totalValueLocked

  • summary: The sum of funds across all pools.

    This might be lower but never higher than the sum of total_balance of all [PoolMembers] because calling pool_withdraw_unbonded might decrease the total stake of the pool's bonded_account without adjusting the pallet-internal UnbondingPool's.


offences

  • interface: api.query.onDemandAssignmentProvider.paraIdAffinity
  • summary: Maps a ParaId to CoreIndex and keeps track of how many assignments the scheduler has in it's lookahead. Keeping track of this affinity prevents parallel execution of the same ParaId on two or more CoreIndexes.

queueStatus(): PolkadotRuntimeParachainsAssignerOnDemandTypesQueueStatusType

  • interface: api.query.paraInclusion.v1
  • summary: Candidates pending availability by ParaId. They form a chain starting from the latest included head of the para. Use a different prefix post-migration to v1, since the v0 PendingAvailability storage would otherwise have the exact same prefix which could cause undefined behaviour when doing the migration.

paraInherent

included(): Option<Null>

  • interface: api.query.paraInherent.included

  • summary: Whether the paras inherent was included within this block.

    The Option<()> is effectively a bool, but it never hits storage in the None variant due to the guarantees of FRAME's storage APIs.

  • interface: api.query.paras.pastCodePruning
  • summary: Which paras have past code that needs pruning and the relay-chain block at which the code was replaced. Note that this is the actual height of the included block, not the expected height at which the code upgrade would be applied, although they may be equal. This is to ensure the entire acceptance period is covered, not an offset acceptance period starting from the time at which the parachain perceives a code upgrade as having occurred. Multiple entries for a single para are permitted. Ordered ascending by block number.

pvfActiveVoteList(): Vec<H256>

  • interface: api.query.paras.pvfActiveVoteList
  • summary: The list of all currently active PVF votes. Auxiliary to PvfActiveVoteMap.

pvfActiveVoteMap(H256): Option<PolkadotRuntimeParachainsParasPvfCheckActiveVoteState>

  • summary: All currently active PVF pre-checking votes.

    Invariant:

    • There are no PVF pre-checking votes that exists in list but not in the set and vice versa.

  • interface: api.query.paras.upcomingParasGenesis

  • summary: Upcoming paras instantiation arguments.

  • interface: api.query.paras.upgradeGoAheadSignal

  • summary: This is used by the relay-chain to communicate to a parachain a go-ahead with in the upgrade procedure.

    This value is absent when there are no upgrades scheduled or during the time the relay chain performs the checks. It is set at the first relay-chain block when the corresponding parachain can switch its upgrade function. As soon as the parachain's block is included, the value gets reset to None.

    NOTE that this field is used by parachains via merkle storage proofs, therefore changing the format will require migration of parachains.

upgradeRestrictionSignal(u32): Option<PolkadotPrimitivesV7UpgradeRestriction>

  • interface: api.query.paras.upgradeRestrictionSignal

  • summary: This is used by the relay-chain to communicate that there are restrictions for performing an upgrade for this parachain.

    This may be a because the parachain waits for the upgrade cooldown to expire. Another potential use case is when we want to perform some maintenance (such as storage migration) we could restrict upgrades to make the process simpler.

    NOTE that this field is used by parachains via merkle storage proofs, therefore changing the format will require migration of parachains.


paraScheduler

availabilityCores(): Vec<PolkadotRuntimeParachainsSchedulerPalletCoreOccupied>

  • interface: api.query.paraScheduler.availabilityCores

  • summary: One entry for each availability core. The i'th parachain belongs to the i'th core, with the remaining cores all being on demand parachain multiplexers.

    Bounded by the maximum of either of these two values:

    • The number of parachains and parathread multiplexers

sessionStartBlock(): u32

  • interface: api.query.paraScheduler.sessionStartBlock

  • summary: The block number where the session start occurred. Used to track how many group rotations have occurred.

    Note that in the context of parachains modules the session change is signaled during the block and enacted at the end of the block (at the finalization stage, to be exact). Thus for all intents and purposes the effect of the session change is observed at the block following the session change, block number of which we save in this storage value.

validatorGroups(): Vec<Vec<u32>>

  • interface: api.query.paraScheduler.validatorGroups

  • summary: All the validator groups. One for each core. Indices are into ActiveValidators - not the broader set of Polkadot validators, but instead just the subset used for parachains during this session.

    Bound: The number of cores is the sum of the numbers of parachains and parathread multiplexers. Reasonably, 100-1000. The dominant factor is the number of validators: safe upper bound at 10k.

  • interface: api.query.staking.nominators

  • summary: 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 account's [NominationsQuota::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.

    TWOX-NOTE: SAFE since AccountId is a secure hash.
