Expand description
Bitcoin block header.
Contains all the block’s information except the actual transactions, but including a root of a merkle tree commiting to all transactions in the block.
Bitcoin Core References
Fields§
§version: Version
Block version, now repurposed for soft fork signalling.
prev_blockhash: BlockHash
Reference to the previous block in the chain.
merkle_root: TxMerkleNode
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: CompactTarget
The target value below which the blockhash must lie.
nonce: u32
The nonce, selected to obtain a low enough blockhash.
Implementations§
§impl Header
impl Header
pub fn block_hash(&self) -> BlockHash
pub fn block_hash(&self) -> BlockHash
Returns the block hash.
pub fn target(&self) -> Target
pub fn target(&self) -> Target
Computes the target (range [0, T] inclusive) that a blockhash must land in to be valid.
pub fn difficulty(&self) -> u128
pub fn difficulty(&self) -> u128
Computes the popular “difficulty” measure for mining.
pub fn difficulty_float(&self) -> f64
pub fn difficulty_float(&self) -> f64
Computes the popular “difficulty” measure for mining and returns a float value of f64.
pub fn validate_pow(&self, required_target: Target) -> Result<BlockHash, Error>
pub fn validate_pow(&self, required_target: Target) -> Result<BlockHash, Error>
Checks that the proof-of-work for the block is valid, returning the block hash.
pub fn work(&self) -> Work
pub fn work(&self) -> Work
Returns the total work of the block.
