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 *big.Int) *big.Int

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

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 VerifyGaslimit

func VerifyGaslimit(parentGasLimit, headerGasLimit uint64) error

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