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 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 VerifyForkHashes

func VerifyForkHashes(config *params.ChainConfig, header *types.Header, uncle bool) error

VerifyForkHashes verifies that blocks conforming to network hard-forks do have the correct hashes, to avoid clients going off on different chains. This is an optional feature.

func VerifyGaslimit

func VerifyGaslimit(parentGasLimit, headerGasLimit uint64) error

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