Blocks

Blocks are the building blocks of blockchains and rollups.

A block contains transactions which will alter the state of an EVM system incrementally. Transaction within a block can only be executed one after the other, not in parallel.

Table Columns

Column Name	Description
timestamp	The unix timestamp for when the block was collated.
number	The length of the chain, in blocks.
hash	Unique identifier for that block.
parent_hash	Unique identifier of the block preceding this block, also known as the parent block.
nonce	Nonce value.
sha3_uncles	An array of uncle hashes.
logs_bloom	The bloom filter for the logs of the block.
transactions_root	The root of the transaction trie of the block.
state_root	The root of the final state trie of the block.
receipts_root	The root of the receipts trie of the block.
miner	Proof of Stake Address receiving fees from transactions in this block Proof of Work Address of the miner that mined this block.
difficulty	The integer of the difficulty for this block.
total_difficulty	The integer of the total difficulty of the chain until this block.
size	The size of the block, in bytes, as determined by the gas_limit.
extra_data	The "extra data" field of this block.
gas_limit	Gas limit of the current block.
gas_used	Total gas used in the block.
transaction_count	Number of transactions included in this block.
base_fee_per_gas	Post London Upgrade (EIP1559), this represents the minimum gas_used required for a transaction to be included in a block. Represented in wei.
