Calls

heartbeat

Namespace

api.tx.imOnline.heartbeat

Type

function heartbeat(
  heartbeat: PalletImOnlineHeartbeat,
  signature: PalletImOnlineSr25519AppSr25519Signature
)

Storage

authoredBlocks

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

Namespace

api.query.imOnline.authoredBlocks

Type

function authoredBlocks(
  u32,
  SeedPrimitivesSignatureAccountId20
): u32

heartbeatAfter

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.

Namespace

api.query.imOnline.heartbeatAfter

Type

function heartbeatAfter(

): u32

keys

The current set of keys that may issue a heartbeat.

Namespace

api.query.imOnline.keys

Type

function keys(

): Vec<PalletImOnlineSr25519AppSr25519Public>

receivedHeartbeats

For each session index, we keep a mapping of SessionIndex and AuthIndex to WrapperOpaque<BoundedOpaqueNetworkState>.

Namespace

api.query.imOnline.receivedHeartbeats

Type

function receivedHeartbeats(
  u32,
  u32
): Option<WrapperOpaque<PalletImOnlineBoundedOpaqueNetworkState>>

Events

AllGood

At the end of the session, no offence was committed.

Namespace

api.events.imOnline.AllGood

Type

type AllGood = {

}

HeartbeatReceived

A new heartbeat was received from AuthorityId.

Namespace

api.events.imOnline.HeartbeatReceived

Type

type HeartbeatReceived = {
  authority_id: PalletImOnlineSr25519AppSr25519Public
}

SomeOffline

At the end of the session, at least one validator was found to be offline.

Namespace

api.events.imOnline.SomeOffline

Type

type SomeOffline = {
  offline: Vec<(SeedPrimitivesSignatureAccountId20,PalletStakingExposure)>
}

Errors

DuplicatedHeartbeat

Duplicated heartbeat.

Namespace

api.errors.imOnline.DuplicatedHeartbeat

InvalidKey

Non existent public key.

Namespace

api.errors.imOnline.InvalidKey

Constants

unsignedPriority

A configuration for base priority of unsigned transactions.

This is exposed so that it can be tuned for particular runtime, when multiple pallets send unsigned transactions.

Namespace

api.consts.imOnline.unsignedPriority

Type

type unsignedPriority = u64
