  • 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

randomness(): [u8;32]

  • interface: api.query.babe.randomness

    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.

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

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


account(AccountId32): PalletBalancesAccountData

  • interface: api.query.balances.account

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


    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.


    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.

locks(AccountId32): Vec<PalletBalancesBalanceLock>

  • interface: api.query.balances.locks
  • summary: Any liquidity locks on some account balances. NOTE: Should only be accessed when setting, changing and freeing a lock.

  • summary: A mapping between an original code hash and instrumented wasm code, ready for execution.

contractInfoOf(AccountId32): Option<PalletContractsStorageContractInfo>

  • interface: api.query.contracts.contractInfoOf

  • summary: The code associated with a given account.

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

deletionQueue(): Vec<PalletContractsStorageDeletedContract>

  • interface: api.query.contracts.deletionQueue

  • summary: Evicted contracts that await child trie deletion.

    Child trie deletion is a heavy operation depending on the amount of storage items stored in said trie. Therefore this operation is performed lazily in on_initialize.

nonce(): u64

  • interface: api.query.contracts.nonce

  • summary: This is a monotonic counter incremented on contract instantiation.

    This is used in order to generate unique trie ids for contracts. The trie id of a new contract is calculated from hash(account_id, nonce). The nonce is required because otherwise the following sequence would lead to a possible collision of storage:

    1. Create a new contract. 2. Terminate the contract. 3. Immediately recreate the contract with the same account_id.

      This is bad because the contents of a trie are deleted lazily and there might be storage of the old instantiation still in it when the new contract is created. Please note that we can't replace the counter by the block number because the sequence above can happen in the same block. We also can't keep the account counter in memory only because storage is the only way to communicate across different extrinsics in the same block.


      Do not use it to determine the number of contracts. It won't be decremented if a contract is destroyed.

ownerInfoOf(H256): Option<PalletContractsWasmOwnerInfo>

  • interface: api.query.contracts.ownerInfoOf

  • summary: True if the last referendum tabled was submitted externally. False if it was a public proposal.

lowestUnbaked(): u32

  • interface: api.query.democracy.lowestUnbaked

nextExternal(): Option<(FrameSupportPreimagesBounded,PalletDemocracyVoteThreshold)>

  • interface: api.query.democracy.nextExternal

  • summary: The referendum to be tabled whenever it would be valid to table an external proposal. This happens when a referendum needs to be tabled and one of two conditions are met:

    • LastTabledWasExternal is false; or

    • PublicProps is empty.

publicPropCount(): u32

    This is merely incremented once per every time that an upstream elect is called.

signedSubmissionIndices(): Vec<(SpNposElectionsElectionScore,u32,u32)>

  • interface: api.query.electionProviderMultiPhase.signedSubmissionIndices

  • summary: A sorted, bounded vector of (score, block_number, index), where each index points to a value in SignedSubmissions.

    We never need to process more than a single signed submission at a time. Signed submissions can be quite large, so we're willing to pay the cost of multiple database accesses to access them one at a time instead of reading and decoding all of them at once.

signedSubmissionNextIndex(): u32

  • interface: api.query.electionProviderMultiPhase.signedSubmissionNextIndex

  • summary: The next index to be assigned to an incoming signed submission.

    Every accepted submission is assigned a unique index; that index is bound to that particular submission for the duration of the election. On election finalization, the next index is reset to 0.

    We can't just use SignedSubmissionIndices.len(), because that's a bounded set; past its capacity, it will simply saturate. We can't just iterate over SignedSubmissionsMap, because iteration is slow. Instead, we store the value here.

signedSubmissionsMap(u32): Option<PalletElectionProviderMultiPhaseSignedSignedSubmission>

  • interface: api.query.electionProviderMultiPhase.signedSubmissionsMap

  • summary: Unchecked, signed solutions.

    Together with SubmissionIndices, this stores a bounded set of SignedSubmissions while allowing us to keep only a single one in memory at a time.

    Twox note: the key of the map is an auto-incrementing index which users cannot inspect or affect; we shouldn't need a cryptographically secure hasher.

snapshot(): Option<PalletElectionProviderMultiPhaseRoundSnapshot>

  • interface: api.query.electionProviderMultiPhase.snapshot

  • summary: Snapshot data of the round.

    This is created at the beginning of the signed phase and cleared upon calling elect.

snapshotMetadata(): Option<PalletElectionProviderMultiPhaseSolutionOrSnapshotSize>

queueTotals(): Vec<(u32,u128)>

  • interface: api.query.gilt.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.


currentSetId(): u64

  • interface: api.query.grandpa.currentSetId

  • summary: For each session index, we keep a mapping of ValidatorId<T> to the number of blocks authored by the given authority.

heartbeatAfter(): u32

  • interface: api.query.imOnline.heartbeatAfter

  • summary: The block number after which it's ok to send heartbeats in the current session.

    At the beginning of each session we set this to a value that should fall roughly in the middle of the session duration. The idea is to first wait for the validators to produce a block in the current session, so that the heartbeat later on will not be necessary.

    This value will only be used as a fallback if we fail to get a proper session progress estimate from NextSessionRotation, as those estimates should be more accurate then the value we calculate for HeartbeatAfter.

keys(): Vec<PalletImOnlineSr25519AppSr25519Public>

  • interface: api.query.imOnline.keys
  • summary: The current set of keys that may issue a heartbeat.

  • 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 [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.

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.
