Warp sync backend. Handles retrieveing and verifying warp sync proofs.

Required Methods

fn generate(
    &self,
    start: <Block as Block>::Hash
) -> Result<EncodedProof, Box<dyn Error + Send + Sync + 'static, Global>>

Generate proof starting at given block hash. The proof is accumulated until maximum proof size is reached.

fn verify(
    &self,
    proof: &EncodedProof,
    set_id: u64,
    authorities: Vec<(Public, u64), Global>
) -> Result<VerificationResult<Block>, Box<dyn Error + Send + Sync + 'static, Global>>

Verify warp proof against current set of authorities.

fn current_authorities(&self) -> Vec<(Public, u64), Global>

Get current list of authorities. This is supposed to be genesis authorities when starting sync.
