}

Expand description

An consensus log item for GRANDPA.

Variants

ScheduledChange(ScheduledChange<N>)

Schedule an authority set change.

The earliest digest of this type in a single block will be respected, provided that there is no ForcedChange digest. If there is, then the ForcedChange will take precedence.

No change should be scheduled if one is already and the delay has not passed completely.

This should be a pure function: i.e. as long as the runtime can interpret the digest type it should return the same result regardless of the current state.

ForcedChange(N, ScheduledChange<N>)

Force an authority set change.

Forced changes are applied after a delay of imported blocks, while pending changes are applied after a delay of finalized blocks.

The earliest digest of this type in a single block will be respected, with others ignored.

No change should be scheduled if one is already and the delay has not passed completely.

This should be a pure function: i.e. as long as the runtime can interpret the digest type it should return the same result regardless of the current state.

OnDisabled(AuthorityIndex)

Note that the authority with given index is disabled until the next change.

Pause(N)

A signal to pause the current authority set after the given delay. After finalizing the block at delay the authorities should stop voting.

Resume(N)

A signal to resume the current authority set after the given delay. After authoring the block at delay the authorities should resume voting.
