Constants

const (
	Addr_Length uint8 = 4
	Data_Length uint8 = 4
)

A transaction is defined as a json including:

{
	tx_type uint32
	from	[20]byte
	to		[20]byte
	value	uint32
	data	[20]byte
}

e.g., sent by user as: "type=0,from=ABCD,to=DCBA,value=0,data=NONE"

const (
	Type_Num              uint8 = 5
	IntraShard_TX         uint8 = 0
	InterShard_TX_Verify  uint8 = 1
	InterShard_TX_Execute uint8 = 2
	InterShard_TX_Commit  uint8 = 3
	InterShard_TX_Update  uint8 = 4
)
