TotalScore set total score.

func (*Builder) Transaction

func (b *Builder) Transaction(tx *tx.Transaction) *Builder

Transaction add a transaction.

type GasLimit

type GasLimit uint64

GasLimit to support block gas limit validation and adjustment.

func (GasLimit) Adjust

func (gl GasLimit) Adjust(delta int64) uint64
