Expand description

Representation of a step request.

Fields§

§pre_state_hash: Digest

State root hash.

§protocol_version: ProtocolVersion

Protocol version for this request.

§slash_items: Vec<SlashItem>

List of validators to be slashed.

A slashed validator is removed from the next validator set.

§reward_items: Vec<RewardItem>

List of validators that will be rewarded.

§evict_items: Vec<EvictItem>

List of validators to be evicted.

Compared to a slashing, evictions are deactivating a given validator, but his stake is unchanged. A further re-activation is possible.

§next_era_id: EraId

Specifies which era validators will be returned based on next_era_id.

Intended use is to always specify the current era id + 1 which will return computed era at the end of this step request.

§era_end_timestamp_millis: u64

Timestamp in milliseconds representing end of the current era.
