accumulateParentBlockHash
accumulateParentBlockHash(
vm): (currentBlockNumber,parentHash) =>Promise<void>
This method runs the logic of EIP 2935 (save blockhashes to state)
It will put the parentHash of the block to the storage slot of block.number - 1 of the history storage contract.
This contract is used to retrieve BLOCKHASHes in EVM if EIP 2935 is activated.
In case that the previous block of block is pre-EIP-2935 (so we are on the EIP 2935 fork block), additionally
also add the currently available past blockhashes which are available by BLOCKHASH (so, the past 256 block hashes)
Parameters
• vm: BaseVm
Returns
Function
Parameters
• currentBlockNumber: bigint
• parentHash: Uint8Array
Returns
Promise<void>
