Functions ¶
func ApplyDAOHardFork ¶
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:
- 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 VerifyForkHashes ¶
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 ¶ added in v1.0.4
VerifyGaslimit verifies the header gas limit according increase/decrease in relation to the parent gas limit.
