Functions

func NewTxVMContext

func NewTxVMContext(vs *validationState, entry bc.Entry, prog *bc.Program, args [][]byte) *vm.Context

NewTxVMContext generates the vm.Context for BVM

func ValidateBlock

func ValidateBlock(b *bc.Block, parent *state.BlockNode) error

ValidateBlock validates a block and the transactions within.

func ValidateBlockHeader

func ValidateBlockHeader(b *bc.Block, parent *state.BlockNode) error

ValidateBlockHeader check the block's header

Types

type GasState

type GasState struct {
	BTMValue   uint64
	GasLeft    int64
	GasUsed    int64
	GasValid   bool
	StorageGas int64
}

GasState record the gas usage status

func ValidateTx

func ValidateTx(tx *bc.Tx, block *bc.Block) (*GasState, error)

ValidateTx validates a transaction.
