Expand description
A block header, which contains all the block’s information except the actual transactions
Fields
version: u32
The protocol version. Should always be 1.
prev_blockhash: Sha256dHash
Reference to the previous block in the chain
merkle_root: Sha256dHash
The root hash of the merkle tree of transactions in the block
time: u32
The timestamp of the block, as claimed by the miner
bits: u32
The target value below which the blockhash must lie, encoded as a a float (with well-defined rounding, of course)
nonce: u32
The nonce, selected to obtain a low enough blockhash
Implementations
sourceimpl BlockHeader
impl BlockHeader
sourcepub fn target(&self) -> Uint256
