Type Alias sc_client_api::client::ForkBlocks

pub type ForkBlocks<Block> = Option<Vec<(NumberFor<Block>, <Block as BlockT>::Hash)>>;

Expected hashes of blocks at given heights.

This may be used as chain spec extension to set trusted checkpoints, i.e. the client will refuse to import a block with a different hash at the given height.
