Accessors

minerValue

get minerValue(): bigint

Returns

bigint

Defined in

transactionReceipts

get transactionReceipts(): TxReceipt[]

Returns

TxReceipt[]

Methods

addTransaction()

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.

Parameters

• tx: TypedTransaction | ImpersonatedTx

• __namedParameters = {}

• __namedParameters.skipHardForkValidation?: boolean

Returns

Promise<RunTxResult>

packages/vm/src/actions/BlockBuilder.ts:216

build()

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 nonce and mixHash, which is validated along with the block number and difficulty by ethash. For PoA, please pass blockOption.cliqueSigner into the buildBlock constructor, as the signer will be awarded the txs amount spent on gas as they are added.
