Functions

func ApplyDAOHardFork

func ApplyDAOHardFork(statedb *state.StateDB)

ApplyDAOHardFork modifies the state database according to the DAO hard-fork rules, transferring all balances of a set of DAO accounts to a single refund contract.

func CalcBaseFee

func CalcBaseFee(config *params.ChainConfig, parent *types.Header) *big.Int

CalcBaseFee calculates the basefee of the header.

func CalcBlobFee

func CalcBlobFee(excessDataGas uint64) *big.Int

CalcBlobFee calculates the blobfee from the header's excess data gas field.

func CalcExcessDataGas

func CalcExcessDataGas(parentExcessDataGas uint64, parentDataGasUsed uint64) uint64

CalcExcessDataGas calculates the excess data gas after applying the set of blobs on top of the excess data gas.

func VerifyDAOHeaderExtraData

func VerifyDAOHeaderExtraData(config *params.ChainConfig, header *types.Header) error

VerifyDAOHeaderExtraData validates the extra-data field of a block header to ensure it conforms to DAO hard-fork rules.

DAO hard-fork extension to the header validity:

• if the node is no-fork, do not accept blocks in the [fork, fork+10) range with the fork specific extra-data set.
• if the node is pro-fork, require blocks in the specific range to have the unique extra-data set.

func VerifyEIP1559Header

func VerifyEIP1559Header(config *params.ChainConfig, parent, header *types.Header) error

VerifyEIP1559Header verifies some header attributes which were changed in EIP-1559, - gas limit check - basefee check

func VerifyEIP4844Header

func VerifyEIP4844Header(parent, header *types.Header) error

VerifyEIP4844Header verifies the presence of the excessDataGas field and that if the current block contains no transactions, the excessDataGas is updated accordingly.

func VerifyGaslimit

func VerifyGaslimit(parentGasLimit, headerGasLimit uint64) error

VerifyGaslimit verifies the header gas limit according increase/decrease in relation to the parent gas limit.
