The BlockHeader contains all the metadata for the block, including proof of work, a link to the previous block and the transaction kernels.

Fields

hash: Vec<u8>

The hash of the block

version: u32

Version of the block

height: u64

Height of this block since the genesis block (height 0)

prev_hash: Vec<u8>

Hash of the block previous to this in the chain.

timestamp: u64

Timestamp at which the block was built.

output_mr: Vec<u8>

This is the UTXO merkle root of the outputs in the blockchain

block_output_mr: Vec<u8>

This is the merkle root of all outputs in this block

kernel_mr: Vec<u8>

This is the MMR root of the kernels

input_mr: Vec<u8>

This is the Merkle root of the inputs in this block

total_kernel_offset: Vec<u8>

Total accumulated sum of kernel offsets since genesis block. We can derive the kernel offset sum for this block from the total kernel offset of the previous block header.

nonce: u64

Nonce increment used to mine this block.

pow: Option<ProofOfWork>

Proof of work metadata

kernel_mmr_size: u64

Kernel MMR size

output_mmr_size: u64

Output MMR size

total_script_offset: Vec<u8>

Sum of script offsets for all kernels in this block.

validator_node_mr: Vec<u8>

Merkle root of validator nodes

validator_node_size: u64

Validator size
