Expand description

Essential info extracted from a header.

Fields§

§number: u64

The number of ancestor blocks of this block (block height).

§beneficiary: Address

Beneficiary (Coinbase or miner) is a address that have signed the block.

This is the receiver address of all the gas spent in the block.

§timestamp: u64

The timestamp of the block in seconds since the UNIX epoch

§gas_limit: u64

The gas limit of the block

§base_fee_per_gas: Option<u64>

The base fee per gas, added in the London upgrade with EIP-1559

§excess_blob_gas: Option<u64>

A running total of blob gas consumed in excess of the target, prior to the block. Blocks with above-target blob gas consumption increase this value, blocks with below-target blob gas consumption decrease it (bounded at 0). This was added in EIP-4844.

§blob_gas_used: Option<u64>

The total amount of blob gas consumed by the transactions within the block, added in EIP-4844.

§difficulty: U256

The difficulty of the block

Unused after the Paris (AKA the merge) upgrade and replaced by prevrandao and expected to be 0.

§mix_hash: Option<B256>

The output of the randomness beacon provided by the beacon chain

Replaces difficulty after the Paris (AKA the merge) upgrade with EIP-4399.

Note: prevrandao can be found in a block in place of mix_hash.
