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 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:

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