Trait Implementations§

Get current account nonce of given AccountId.
Retrieve authority identifiers of the current and next authority set.
Return the configuration for BABE.
Returns the slot that started the current epoch.
Returns information regarding the current epoch.
Returns information regarding the next epoch (which was already previously announced). Read more
Generates a proof of key ownership for the given authority in the current epoch. An example usage of this module is coupled with the session historical module to prove that a given authority key is tied to a given staking identity during a specific session. Proofs of key ownership are necessary for submitting equivocation reports. NOTE: even though the API takes a slot as parameter the current implementations ignores this parameter and instead relies on this method being called at the correct block height, i.e. any point at which the epoch for the given slot is live on-chain. Future implementations will instead use indexed data through an offchain worker, not requiring older states to be available. Read more
Submits an unsigned extrinsic to report an equivocation. The caller must provide the equivocation proof and a key ownership proof (should be obtained using generate_key_ownership_proof). The extrinsic will be unsigned and should only be accepted for local authorship (not to be broadcast to the network). This method returns None when creation of the extrinsic fails, e.g. if equivocation reporting is disabled for the given runtime (i.e. this method is hardcoded to return None). Only useful in an offchain context. Read more

The expected average block time at which BABE should be creating blocks. Since BABE is probabilistic it is not trivial to figure out what the expected average block time should be based on the slot duration and the security parameter c (where 1 - c represents the probability of a slot being empty). Read more
BABE requires some logic to be triggered on every block to query for whether an epoch has ended and to perform the transition to the next epoch. Read more
