• blobGasUsed: bigint = BIGINT_0
The cumulative blob gas used by the blobs in a block
• gasUsed: bigint = BIGINT_0
The cumulative gas used by the transactions added to the block.

• get transactionReceipts(): TxReceipt[]
▸ addTransaction(tx, __namedParameters?): Promise<RunTxResult>
Run and add a transaction to the block being built. Please note that this modifies the state of the VM. Throws if the transaction's gasLimit is greater than the remaining gas in the block.

▸ build(sealOpts?): Promise<Block>
This method returns the finalized block. It also:
- Assigns the reward for miner (PoW)
- Commits the checkpoint on the StateManager
- Sets the tip of the VM's blockchain to this block
For PoW, optionally seals the block with params
nonceandmixHash, which is validated along with the block number and difficulty by ethash. For PoA, please passblockOption.cliqueSignerinto the buildBlock constructor, as the signer will be awarded the txs amount spent on gas as they are added.
