Struct tendermint::block::Id

pub struct Id {
    pub hash: Hash,
    pub parts: Option<Header>,
}

Block identifiers which contain two distinct Merkle roots of the block, as well as the number of parts in the block.

Fields

hash: Hash

The block's main hash is the Merkle root of all the fields in the block header.

parts: Option<Header>

Parts header (if available) is used for secure gossipping of the block during consensus. It is the Merkle root of the complete serialized block cut into parts.

PartSet is used to split a byteslice of data into parts (pieces) for transmission. By splitting data into smaller parts and computing a Merkle root hash on the list, you can verify that a part is legitimately part of the complete data, and the part can be forwarded to other peers before all the parts are known. In short, it's a fast way to propagate a large file over a gossip network.
