[−][src]Struct bitcoin::blockdata::block::BlockHeader
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: Hash
Reference to the previous block in the chain
merkle_root: Hash
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
Methods
impl BlockHeader
[src]
pub fn target(&self) -> Uint256
[src]
Computes the target [0, T] that a blockhash must land in to be valid
pub fn compact_target_from_u256(value: &Uint256) -> u32
[src]
Computes the target value in float format from Uint256 format.
pub fn difficulty(&self, network: Network) -> u64
[src]
Compute the popular "difficulty" measure for mining
pub fn spv_validate(&self, required_target: &Uint256) -> Result<(), Error>
[src]
Performs an SPV validation of a block, which confirms that the proof-of-work is correct, but does not verify that the transactions are valid or encoded correctly.
pub fn work(&self) -> Uint256
[src]
Returns the total work of the block
