@ethereumjs/vm / RunBlockOpts

Interface: RunBlockOpts

Defined in: vm/src/types.ts:260

Options for running a block.

Properties

block

block: Block

Defined in: vm/src/types.ts:264

The Block to process

---

blockAccessList?

optional blockAccessList?: Uint8Array<ArrayBufferLike> | BlockLevelAccessList | BALJSONBlockAccessList

Defined in: vm/src/types.ts:340

Block-level access list supplied with the block (e.g. from an execution payload). When set and EIP-7928 is active, runBlock validates structure and header hash before execution and RLP equality against the generated list after execution.

Remarks

Experimental (Amsterdam): may change on patch releases. See @ethereumjs/vm README section Amsterdam hardfork (experimental) for release ↔ spec tracking.

---

clearCache?

optional clearCache?: boolean

Defined in: vm/src/types.ts:276

Clearing the StateManager cache.

If state root is not reset for whatever reason this can be set to false for better performance.

Default: true

---

generate?

optional generate?: boolean

Defined in: vm/src/types.ts:283

Whether to generate the stateRoot and other related fields. If true, runBlock will set the fields stateRoot, receiptTrie, gasUsed, and bloom (logs bloom) after running the block. If false, runBlock throws if any fields do not match. Defaults to false.

---

reportPreimages?

optional reportPreimages?: boolean

Defined in: vm/src/types.ts:324

If true, adds a hashedKey -> preimages mapping of all touched accounts to the RunTxResult returned.

---

root?

optional root?: Uint8Array<ArrayBufferLike>

Defined in: vm/src/types.ts:268

Root of the state trie

---

setHardfork?

optional setHardfork?: boolean

Defined in: vm/src/types.ts:318

Set the hardfork either by timestamp (for HFs from Shanghai onwards) or by block number for older Hfs.

Default: false (HF is set to whatever default HF is set by the @ethereumjs/common!Common instance)

---

skipBalance?

optional skipBalance?: boolean

Defined in: vm/src/types.ts:311

If true, checks the balance of the from account for the transaction and sets its balance equal equal to the upfront cost (gas limit * gas price + transaction value)

---

skipBlockValidation?

optional skipBlockValidation?: boolean

Defined in: vm/src/types.ts:290

If true, will skip “Block validation”: Block validation validates the header (with respect to the blockchain), the transactions, the transaction trie and the uncle hash.

---

skipHardForkValidation?

optional skipHardForkValidation?: boolean

Defined in: vm/src/types.ts:295

If true, skips the hardfork validation of vm, block and tx

---

skipHeaderValidation?

optional skipHeaderValidation?: boolean

Defined in: vm/src/types.ts:302

if true, will skip “Header validation” If the block has been picked from the blockchain to be executed, header has already been validated, and can be skipped especially when consensus of the chain has moved ahead.

---

skipNonce?

optional skipNonce?: boolean

Defined in: vm/src/types.ts:306

If true, skips the nonce check

---

validateBlockSize?

optional validateBlockSize?: boolean

Defined in: vm/src/types.ts:330

If true, will validate block size limit (EIP-7934) when validating block data. Defaults to false.
