Expand description

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

Required methods

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

Verify warp proof against current set of authorities.

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