Struct polkadot_sdk_frame::runtime::apis::EquivocationProof

pub struct EquivocationProof<H, N> { /* private fields */ }

Proof of voter misbehavior on a given set id. Misbehavior/equivocation in GRANDPA happens when a voter votes on the same round (either at prevote or precommit stage) for different blocks. Proving is achieved by collecting the signed messages of conflicting votes.

Implementations

impl<H, N> EquivocationProof<H, N>

pub fn new( set_id: u64, equivocation: Equivocation<H, N>, ) -> EquivocationProof<H, N>

Create a new EquivocationProof for the given set id and using the given equivocation as proof.

pub fn set_id(&self) -> u64

Returns the set id at which the equivocation occurred.

pub fn round(&self) -> u64

Returns the round number at which the equivocation occurred.

pub fn offender(&self) -> &Public

Returns the authority id of the equivocator.
