Function sp_finality_grandpa::check_equivocation_proof

pub fn check_equivocation_proof<H, N>(report: EquivocationProof<H, N>) -> bool where
    H: Clone + Encode + PartialEq,
    N: Clone + Encode + PartialEq, 

Verifies the equivocation proof by making sure that both votes target different blocks and that its signatures are valid.
